FNC_TblOpGetHashByDef Function | C Library Functions | Teradata Vantage - FNC_TblOpGetHashByDef - Analytics Database - Teradata Vantage

Retrieves the HASH BY clause information of the input stream for a table operator.

Syntax

void
FNC_TblOpGetHashByDef(int           streamno,
                      FNC_Names_t  *out_colname);

Syntax Elements

streamno

the input stream number.

out_colname

a pointer to the location where the column names will be stored.

For details about the FNC_Names_t structure, see Table Operator Data Structures.

Usage Notes

Before calling FNC_TblOpGetHashByDef, you must allocate memory for the out_colname buffer:

FNC_Names_t *out_colname = FNC_malloc(TblOpSIZEHASHBY(
                               FNC_TblOpCountHashByDef(streamno)) );

You must release the allocated memory when out_colname is no longer needed. If you used FNC_malloc to allocate the memory, use FNC_free to release it.
