ctdbSetFieldAsCurrency

Set field as a currency value.

Declaration

CTDBRET ctdbSetFieldAsCurrency(CTHANDLE Handle, NINT FieldNbr,

CTCURRENCY Value)

Description

ctdbSetFieldAsCurrency() sets a field as currency value. Use ctdbGetFieldAsCurrency() to retrieve a field as a currency value.

Handle [in] the record handle.
FieldNbr [in] the field number to be set. To retrieve the field number given the field name, use ctdbGetFieldNumberByName().
Value [in] the currency value.

Truncation of Values (behavior before V12.5)

The SetFieldAs family of functions behave differently for fixed-length fields vs. variable-length fields:

Variable-length Fields - If the value passed to the SetFieldAs function exceeds the size of the field, it will be stored in the field in its entirety without truncation. Variable-length fields are allowed to exceed the declared field size. If truncation is desired, it will be necessary to check the size of the value and truncate it before passing it to the function. Because SQL cannot handle string fields that are longer than the set limit, your application will need logic to enforce the limit if the table will be opened with SQL.

Fixed-length Fields - If the value passed to the SetFieldAs function exceeds the size of the field, it will be truncated to the length of the field. The following types of fields are truncated at the FairCom DB API level:

SQL type: CHAR
CTDB types: CT_FSTRING, CT_FPSTRING, CT_F2STRING, CT_F4STRING

Returns

ctdbSetFieldAsCurrency() returns CTDBRET_OK if successful, or the c-tree error code on failure.
