This function is used to build up a row by adding values for columns of the tables involved in the query. This function requires the data to be passed in using the same data type as the column definition or in any format from which data conversion is supported. Character data can be added by supplying the length or marking the data as null terminated. NULL data is added by specifying the XO_NULL_DATA value flag for the value length.

This function copies data from the user supplied buffer to its internal buffers. The IP can free the memory associated with the input buffer (pColVal).

int damex_addColValToRow(
    DAM_HSTMT  hstmt, 
    DAM_HROW  hRow,
    DAM_HCOL  hCol, 
    int       iXoType,
    void    * pColVal,
    long      lColValLen)

Parameters for damex_addColValToRow

Parameter	Type	Description
IN
hstmt	DAM_HSTMT	The statement handle.
hRow	DAM_HROW	The row handle.
hCol	DAM_HCOL	The column handle.
iXoType	int	The type of the data. The data can be supplied in a format that corresponds to the column's definition in the schema or in any other format and the OpenAccess SDK SQL engine will perform the required conversion.
pColVal	void *	The pointer to the data; the C type of the data should correspond to the iXoType value. See Table SQL Engine Data Types and the Corresponding C Types.
lColValLen	long	The length of the data: XO_NULL_DATA - indicates a null value. For VARCHAR, CHAR and NUMERIC either the length of the string or XO_NTS if the string is null terminated. For all other data types, the length of the data. The length value is required so that OpenAccess SDK can validate that the correct data size is passed in for the iXoType.
RETURN
	int	DAM_SUCCESS - added the value to the row. DAM_FAILURE - error adding the value.
