) -> SqlReturn

Returns the current settings or values of multiple fields of a descriptor record. The fields returned describe the name, data type, and storage of column or parameter data.

Returns

SUCCESS, SUCCESS_WITH_INFO, ERROR, SQL_NO_DATA, or INVALID_HANDLE. SQL_NO_DATA is returned if RecNumber is greater than the current number of descriptor records. SQL_NO_DATA is returned if DescriptorHandle is an IRD handle and the statement is in the prepared or executed state but there was no open cursor associated with it.
