Get Indicator Function (Array-Based Mode)

Get Indicator Function (Array-Based Mode)

Use the get indicator function when you want the procedure to verify if the input port has a null value.
Use the following syntax:
INFA_INDICATOR INFA_CTAGetIndicator( INFA_CT_INPUTPORT_HANDLE inputport, INFA_INT32 iRow );
The following table describes the arguments for this function:
Argument
Datatype
Input/
Output
Description
inputport
INFA_CT_INPUTPORT_HANDLE
Input
Input port handle.
iRow
INFA_INT32
Input
Index number of the row in the block. The index is zero-based.
You must verify the procedure only passes an index number that exists in the data block. If you pass an invalid value, the Integration Service shuts down unexpectedly.
The return value datatype is INFA_INDICATOR. Use the following values for INFA_INDICATOR:
  • INFA_DATA_VALID.
    Indicates the data is valid.
  • INFA_NULL_DATA.
    Indicates a null value.
  • INFA_DATA_TRUNCATED.
    Indicates the data has been truncated.
