Use the listTables JSON API action to list tables in the specified database that the logged-in user is allowed to see
The "params"
property is an object that contains an action's parameters. Each action defines its own required and optional properties.
Properties summary
"params"
properties summaryProperty | Description | Default | Type | Limits (inclusive) | ||
---|---|---|---|---|---|---|
specifies the name of a database | Defaults to the | string | 1 to 64 bytes | |||
includeSystemTables | includes the system tables in the list of tables when |
| Boolean |
| ||
specifies the maximum number of records to return from an action. |
| integer |
| |||
specifies the unique name of a schema in a database |
| string | 1 to 64 bytes | |||
filters the returned databases by applying partial matches to database names |
| string | 0 to 64 bytes | |||
specifies the number of records to skip over in the results before returning records |
| integer |
| |||
lists table names to return in the response message |
| array | 1 to 64 bytes |
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.
A zero-length
"databaseName"
is invalid.Its limits are from 0 to 64 bytes.
If the
"databaseName"
property is omitted or set tonull
, 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 theservices.json
file.
The "maxRecords"
is an optional integer from -1
to 65,535
that sets the maximum number of records to return from an action. It is used in query actions to paginate the query results when returning records directly. The default for most actions is to return 20
records.
Important
-1
returns all records and should be used very carefully because a large query can return so many records that it eventually times out and wastes server and client resources.
When present,
"maxRecords"
works in conjunction with the"skipRecords"
(and, when applicable,"reverseOrder"
) properties to paginate results."maxRecords"
returns an error when"returnCursor"
istrue
.Note
This does not apply to the actions where
"returnCursor"
is not present.When returning a cursor, retrieve records using the
"getRecordsFromCursor"
action.A value of
0
for"maxRecords"
is not useful because it causes the action to return no records."maxRecords"
is ignored by the"getRecordsByIds"
action.
The "ownerName"
property is an optional string from 1 to 64 bytes that specifies the account that owns an object.
The "partialTableName"
property is an optional string from 0 to 64 bytes that filters the returned databases by applying partial matches to database names. It defaults to an empty string.
The
"listTables"
action uses"partialTableName"
to return all tables whose table names start with these same characters.A zero-length string matches all table names.
The "skipRecords"
property is an optional integer from 0
to 9,223,372,036,854,775,807
. It is used in query actions to paginate the query results when returning records directly. It defaults to 0
.
It specifies the number of records to skip over in the results before returning records.
It works with
"maxRecords"
and"reverseOrder"
.It is ignored when
"returnCursor"
istrue
.Note
This does not apply to the actions where
"returnCursor"
is not present.
The "tableNames"
property is a required array of strings. Each string is from 1 to 64 bytes.
Contains at least one string.
Each string is the name of a table.
A zero-length
"tableName"
is invalid.A client should force the uniqueness of items in the array because the server ignores duplicate items.
Properties summary
"result"
properties summaryProperty | Description | Type | Limits (inclusive) | |||
---|---|---|---|---|---|---|
data | specifies an array or object that the server returns, such as records returned by a query. It is an empty array when no results are available. | array | Its contents are determined by the action | |||
specifies the format of the data in the | string |
|
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"
.
"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.
