Number of Rows Functions

Number of Rows Functions

Use the number of rows functions to determine the number of rows in an input block, or to set the number of rows in an output block for the specified input or output group.
PowerCenter provides the following number of rows functions:
  • INFA_CTAGetNumRows().
    You can determine the number of rows in an input block.
    Use the following syntax:
    INFA_INT32 INFA_CTAGetNumRows( INFA_CT_INPUTGROUP_HANDLE inputgroup );
    The following table describes the argument for this function:
    Argument
    Datatype
    Input/
    Output
    Description
    inputgroup
    INFA_CT_INPUTGROUP_HANDLE
    Input
    Input group handle.
  • INFA_CTASetNumRows().
    You can set the number of rows in an output block. Call this function before you call the output notification function.
    Use the following syntax:
    void INFA_CTASetNumRows( INFA_CT_OUTPUTGROUP_HANDLE outputgroup, INFA_INT32 nRows );
    The following table describes the arguments for this function:
    Argument
    Datatype
    Input/
    Output
    Description
    outputgroup
    INFA_CT_OUTPUTGROUP_HANDLE
    Input
    Output port handle.
    nRows
    INFA_INT32
    Input
    Number of rows you want to define in the output block. You must enter a positive number. The Integration Service fails the output notification function when specify a non-positive number.
