"binaryFormat"

The "binaryFormat" property designates how binary values are formatted in the JSON request and JSON response message. The default value is "base64".

Note

Typically, response options apply only to the server’s response, but the "binaryFormat" property applies to both the request and the response.

Things to know:

  • The "binaryFormat" property may occur inside "params",  "responseOptions", "defaultResponseOptions" , and "result".

  • When "binaryFormat" occurs in "params" it specifies how the sender represents binary values.

    For example, when  "binaryFormat" is set to "hex", the FairCom server expects the binary values of fields and keys to be represented in strings with hexadecimal format.

  • When "binaryFormat" occurs in "responseOptions" or "defaultResponseOptions" it specifies how the FairCom server should represent binary values in responses.

    For example, when "binaryFormat" is set to "hex", the FairCom server represents binary values in strings with hexadecimal format.

  • When "binaryFormat" occurs in "result" it signifies how binary values are represented.

    For example, when "binaryFormat" is set to "base64", the FairCom server represents binary values in the response in base64 format.

  • The following are the possible values for each format.

    • "base64"

      When the server reads and writes from a binary field, it represents the binary value as a base64 string.

      • This is the default

      • "base64" strings contain the following characters:

        • 0-9

        • A-Z

        • a-z

        • +

        • /

        • =

    • "hex"

      When the server reads and writes from a binary field, it represents the binary value as a hexadecimal string.

      • Hexadecimal is easier for people to read and convert to binary.

      • Hexadecimal creates a larger payload than "base64", which makes it less efficient for data transmission.

      • Hexadecimal strings contain the following characters:

        • 0-9

        • A-F

    • "byteArray"

      When the server reads and writes from a binary field, it represents the binary value as an array of bytes.

      • An array of bytes is easiest for a program to manipulate.

      • An array of bytes creates a larger payload than "base64" and "hex", which makes it less efficient for data transmission.

      • An array of bytes returns a JSON array containing one integer number between 0 and 255 for each byte in the binary value:

        • "aBinaryField": [ 255, 0, 255 ]

Examples

Create a "binary_test" table

This example creates a table containing one binary field named "bin" with a fixed length of 5 bytes.

{
  "api": "db",
  "action": "createTable",
  "params": {
    "tableName": "binary_test",
    "fields": [
      {
        "name": "bin",
        "type": "binary",
        "length": 5
      }
    ]
  },
  "authToken": "replaceWithValidAuthtoken"
}
Insert a record into the "binary_test" table using an array of bytes format

This example inserts a record with the ASCII characters "123" in the "bin" field. The value of "bin" is represented as an array of bytes.

{
  "api": "db",
  "action": "insertRecords",
  "params": {
    "tableName": "binary_test",
    "dataFormat": "objects",
    "binaryFormat": "byteArray",
    "sourceData": [
      {
        "bin": [49,50,51]
      }
    ]
  },
  "authToken": "replaceWithValidAuthtoken"
}
Insert a record into the "binary_test" table using hexadecimal format

This example inserts a record with the ASCII characters "123" in the "bin" field. The value of "bin" is represented as a string in hexadecimal format.

{
  "api": "db",
  "action": "insertRecords",
  "params": {
    "tableName": "binary_test",
    "dataFormat": "objects",
    "binaryFormat": "hex",

      {
        "bin": "313233"
      }
    ]
  },
  "authToken": "replaceWithValidAuthtoken"
}
Insert a record into the "binary_test" table using base64 format

This example inserts a record with the ASCII characters "123" in the "bin" field. The value of "bin" is represented as a string in base64 format.

{
  "api": "db",
  "action": "insertRecords",
  "params": {
    "tableName": "binary_test",
    "dataFormat": "objects",
    "binaryFormat": "base64",
    "sourceData": [
      {
        "bin": "MTIz"
      }
    ]
  },
  "authToken": "replaceWithValidAuthtoken"
}
Retrieve a record with "binaryFormat" as an array of bytes

This example requests the first record in the "binary_test" table with the value of "bin" represented as an array of bytes.

{
  "api": "db",
  "action": "getRecordsByTable",
  "params": {
    "tableName": "binary_test",
    "maxRecords": 1

    "binaryFormat": "byteArray",
    "dataFormat": "objects",
    "numberFormat": "number"
  },
  "authToken": "replaceWithValidAuthtoken"
}
Response

Note

Our examples insert only 3 bytes into "bin" . Because the "bin" field has a fixed-length if 5 bytes, the server pads unused bytes with 0x00 and stores the result. When a record is retrieved, the server returns all 5 bytes.

}

"databaseName"

The "databaseName" property is an optional string that specifies the database that contains the tables. It defaults to the database name supplied at login.

Note

In the API Explorer, "defaultDatabaseName" is set to "ctreeSQL" in the "createSession" action that happens at login.

Things to know:

  • A zero-length "databaseName" is invalid.

  • Its limits are from 0 to 64 bytes.

  • If the "databaseName" property is omitted or set to null, the server will use the default database name specified at login.

  • If no default database is specified during "createSession", "defaultDatabaseName" will be set to the "defaultDatabaseName" value that is specified in the services.json file.

"dataFormat"

The "dataFormat" property is an optional, case-insensitive string enum that defines the format of the response in the "data" property. The default format is an array of arrays. The alternative is an array of objects. The default for "dataFormat" can be changed during a "createSession" action by assigning a different value to the "dataFormat" property in "defaultResponseOptions".

There are three different (but similar) versions of the "dataFormat" property:

Two of those versions occur in a request and another occurs in a response. They all indicate how data is formatted.

  • "dataFormat" in the request inside "responseOptions" determines how the "data" property in the response is formatted.

    Possible values include:

    • "arrays"

      This is the default and causes the server to return results as an array of arrays, which is the most efficient.

    • "objects"

      This returns results as an array of objects. This is less efficient but is simpler to generate, read, and troubleshoot.

  • "dataFormat" in the request in the "params" object notifies the server how the "sourceData" property is formatted in the request. This version is rarely used because of the default "autoDetect" behavior.

    Possible values include:

    • "arrays"

      This causes the server to return results as an array of arrays, which is the most efficient.

    • "objects"

      This returns results as an array of objects. This is less efficient but is simpler to generate, read, and troubleshoot.

    • "autoDetect"

      This is the default and causes the server to automatically detect the format of the data in the "sourceData" property.

  • "dataFormat" in the response shows the client how the server formatted the "data" property.

    Possible values include:

    • "arrays"

      This is the default and causes the server to return results as an array of arrays, which is the most efficient.

    • "objects"

      This returns results as an array of objects. This is less efficient but is simpler to generate, read, and troubleshoot.

"fieldNames"

The "fieldNames" property is an optional, case-sensitive array of strings where each string is the name of a field. It defaults to an empty array.

Things to know:

  • "fieldNames" is required in two possible cases:

    • When "dataFormat" is set to "arrays".

    • When "dataFormat" is set to "autoDetect" and the value in "sourceData" is an array of arrays.

  • It is recommended to create tables with all lowercase "fieldNames".

"ownerName"

The "ownerName" property is an optional string from 1 to 64 bytes that specifies the account that owns an object.

Things to know:

  • The "ownerName" property is optional and has a dynamic default value.

  • If the "ownerName" property is omitted or set to null, the server uses the value of the "defaultOwnerName" property supplied during the "createSession" action.

  • If the "defaultOwnerName" property is not defined, the server uses the "admin" as the owner name.

  • The owner of an object has administrative rights over that object.

  • The "ownerName" property is a namespace for an object. You can think of it as a container of objects.

    The "ownerName" allows users to use any name for the objects they create — for example, a QA engineer may copy tables into their owner space to run a set of tests.

    It is common for a user to create their own copies of objects from other accounts for testing, troubleshooting, and fixing data. The copied objects can retain the same name because the "ownerName" distinguishes between them.

  • The fully qualified name of an object is the "databaseName", "ownerName", and the object's name, such as "tableName" meaning a FairCom server may contain many tables with the name "mytable" as long as each one is in a different database or in a different owner space.

    For example, an organization often creates different databases for different phases of the development lifecycle, such as dev, test, stage, ua, and prod. Each of these databases contains the same set of objects with the same names. Applications leave the "databaseName" out of their JSON actions and use the "defaultDatabaseName" property to specify the target database.

  • Queries and scripts are often written without specifying "databaseName" and/or "ownerName", allowing queries and scripts to work properly when run in different databases or in different schemas.

"tableName"

The "tableName" property is an optional string that contains the name of an integration table or MQTT topic that holds the topic's messages. It defaults to an empty string.

Things to know:

  • You can use a topic name for an MQTT table because FairCom automatically generates a table name for each topic.

  • A "tableName" cannot begin with a number.

  • It refers to the name of the integration table that stores a topic’s messages and is used to rename that table or assign a new topic to an existing integration table.

  • MQTT automatically creates an integration table for each new topic it receives. Thus, when a message is sent to a topic, FairCom Edge automatically creates a table to hold it.

  • As you refine your integration processes, you may want to rename an integration table to better label the data it holds. You can use the "tableName" property of the "configureTopic" action to rename an integration table.

  • The "alterIntegrationTable" action can also be used to rename an integration table, but it is less convenient because you must know the original name of the integration table.

"binaryFormat"

The "binaryFormat" property designates how binary values are formatted in the JSON request and JSON response message. The default value is "base64".

Note

Typically, response options apply only to the server’s response, but the "binaryFormat" property applies to both the request and the response.

Things to know:

  • The "binaryFormat" property may occur inside "params",  "responseOptions", "defaultResponseOptions" , and "result".

  • When "binaryFormat" occurs in "params" it specifies how the sender represents binary values.

    For example, when  "binaryFormat" is set to "hex", the FairCom server expects the binary values of fields and keys to be represented in strings with hexadecimal format.

  • When "binaryFormat" occurs in "responseOptions" or "defaultResponseOptions" it specifies how the FairCom server should represent binary values in responses.

    For example, when "binaryFormat" is set to "hex", the FairCom server represents binary values in strings with hexadecimal format.

  • When "binaryFormat" occurs in "result" it signifies how binary values are represented.

    For example, when "binaryFormat" is set to "base64", the FairCom server represents binary values in the response in base64 format.

  • The following are the possible values for each format.

    • "base64"

      When the server reads and writes from a binary field, it represents the binary value as a base64 string.

      • This is the default

      • "base64" strings contain the following characters:

        • 0-9

        • A-Z

        • a-z

        • +

        • /

        • =

    • "hex"

      When the server reads and writes from a binary field, it represents the binary value as a hexadecimal string.

      • Hexadecimal is easier for people to read and convert to binary.

      • Hexadecimal creates a larger payload than "base64", which makes it less efficient for data transmission.

      • Hexadecimal strings contain the following characters:

        • 0-9

        • A-F

    • "byteArray"

      When the server reads and writes from a binary field, it represents the binary value as an array of bytes.

      • An array of bytes is easiest for a program to manipulate.

      • An array of bytes creates a larger payload than "base64" and "hex", which makes it less efficient for data transmission.

      • An array of bytes returns a JSON array containing one integer number between 0 and 255 for each byte in the binary value:

        • "aBinaryField": [ 255, 0, 255 ]

This example inserts a record with the ASCII characters "123" in the "bin" field. The value of "bin" is represented as a string in base64 format.

{
  "api": "db",
  "action": "insertRecords",
  "params": {
    "tableName": "binary_test",
    "dataFormat": "objects",
    "binaryFormat": "base64",
    "sourceData": [
      {
        "bin": "MTIz"
      }
    ]
  },
  "authToken": "replaceWithValidAuthtoken"
}
Retrieve a record with "binaryFormat" as an array of bytes

This example requests the first record in the "binary_test" table with the value of "bin" represented as an array of bytes.

{
  "api": "db",
  "action": "getRecordsByTable",
  "params": {
    "tableName": "binary_test",

  "responseOptions": {
    "binaryFormat": "byteArray",
    "dataFormat": "objects",
    "numberFormat": "number"
  },
  "authToken": "replaceWithValidAuthtoken"
}
Response

Note

Our examples insert only 3 bytes into "bin" . Because the "bin" field has a fixed-length if 5 bytes, the server pads unused bytes with 0x00 and stores the result. When a record is retrieved, the server returns all 5 bytes.

"dataFormat"

The "dataFormat" property is an optional, case-insensitive string enum that defines the format of the response in the "data" property. The default format is an array of arrays. The alternative is an array of objects. The default for "dataFormat" can be changed during a "createSession" action by assigning a different value to the "dataFormat" property in "defaultResponseOptions".

There are three different (but similar) versions of the "dataFormat" property:

Two of those versions occur in a request and another occurs in a response. They all indicate how data is formatted.

  • "dataFormat" in the request inside "responseOptions" determines how the "data" property in the response is formatted.

    Possible values include:

    • "arrays"

      This is the default and causes the server to return results as an array of arrays, which is the most efficient.

    • "objects"

      This returns results as an array of objects. This is less efficient but is simpler to generate, read, and troubleshoot.

  • "dataFormat" in the request in the "params" object notifies the server how the "sourceData" property is formatted in the request. This version is rarely used because of the default "autoDetect" behavior.

    Possible values include:

    • "arrays"

      This causes the server to return results as an array of arrays, which is the most efficient.

    • "objects"

      This returns results as an array of objects. This is less efficient but is simpler to generate, read, and troubleshoot.

    • "autoDetect"

      This is the default and causes the server to automatically detect the format of the data in the "sourceData" property.

  • "dataFormat" in the response shows the client how the server formatted the "data" property.

    Possible values include:

    • "arrays"

      This is the default and causes the server to return results as an array of arrays, which is the most efficient.

    • "objects"

      This returns results as an array of objects. This is less efficient but is simpler to generate, read, and troubleshoot.

"fields"

The "fields" property is a required array of field-type objects. There is one object for each top-level field in the array. Each object identifies the actual data type of the field as stored in the database.

A field-type object is used when creating a table. It contains one object for each field definition returned in the data.

"fields": 
[
    {
      "name": "name",
      "type": "varchar",
      "length": 50,
      "scale": null,
      "defaultValue": null,
      "nullable": false,
      "primaryKey":1
   }
]

"autoValue"

This property controls when and how the server automatically sets the field value.

Specify only one of these values per field.

  • "none" indicates the server does not automatically set the field's value.

  • "incrementOnInsert" indicates the server automatically increments a field’s value each time the server inserts a new record. It applies to fields that are of the type of decimal or one of the integer types, such as "bigint". Only one field per table can have this attribute. The server returns an error when assigning this attribute to multiple fields. The JSON DB API automatically creates the "id" field as an "incrementOnInsert" field. If you apply this attribute to another field, it becomes the only automatically incremented field in the table. If you want that field to be the primary key, assign  "primaryKey": 1 to it.

  • "timestampOnInsert" indicates the server automatically sets a field’s value to the current date and time of an insert. It applies only to fields with a type of "timestamp".

  • "timestampOnUpdate" indicates the server automatically sets a field’s value to the current date and time of an update. It applies only to timestamp fields.

  • "timestampOnUpdateAndInsert" indicates the server automatically sets a field’s value to the current date and time of an insert and an update. It applies only to fields with a type of "timestamp".

  • "changeId" indicates the server uses the field for optimistic locking. The server automatically sets the field's value to the internal transaction number used during the last update of the record. This value changes each time the server updates the record. A table may only have one change tracking field. The field type must be "bigint".

    The JSON DB API automatically creates a "changeid" field with change-tracking functionality.

    Change tracking is optional in the CTDB and ISAM APIs. The application must create a 64-bit integer field and assign change-tracking functionality to it.

A database is a set of data that is managed by a database server. A database contains data that is organized into tables, records, and fields. A database is a huge composite data type that represents a group of interconnected objects. A database allows records to be joined together for querying, searching, and processing by users, applications, and services.

A database is a security container that controls which accounts have permissions to access specific data.
