|Example: lrd_col_data||Retrieval Handling Functions|
Sets a pointer indicating the location of data.
LRDRET lrd_col_data( LRD_CURSOR *mptCursor, unsigned int muiColNum, long mliOffset, LRD_VAR_DESC *mptVarDesc, unsigned long *mpuliFetchedLen, int miDBErrorSeverity);
|mptCursor||A pointer to an LRD_CURSOR structure.|
|muiColNum||The column number of the requested data (one-based).|
|mliOffset||The offset from the beginning of the column data.|
|mptVarDesc||A pointer to the descriptor of a variable which contains the fetched data.|
|mpuliFetchedLen||A pointer to the variable indicating the length of the fetched data.|
|miDBErrorSeverity||The Error Severity Levels of a failure in a database routine.|
The lrd_col_data function sets a pointer to the data of a specific column. This function accesses data without performing a bind operation. Note that to reference data (through pointers) you must cast it to its appropriate type. lrd_col_data only appears in the print.inl file located in the script directory.
When you retrieve data using lrd_col_data, you must convert the character strings into printable data using lrd_to_printable.
For more details refer to the Function Header File lrd.h in the include directory.
See LRD Return Values.
You cannot use standard parameterization for any arguments in this function.
