SQLNextResult - Process the next result set

Purpose

SQLNextResult() determines whether there is more information available on the statement handle that has been associated with a stored procedure that is returning result sets.

Syntax

SQLRETURN   SQLNextResult   (SQLHSTMT          StatementHandle,
                             SQLHSTMT          NextResultHandle);

Function arguments

Table 1. SQLNextResult arguments
Data type Argument Use Description
SQLHSTMT StatementHandle Input Statement handle.
SQLHSTMT NextResultHandle Input Statement handle for next result set.

Usage

This function is used to associate the next result set from StatementHandle with NextResultHandle. This differs from SQLMoreResults() because it allows both statement handles to process their result sets simultaneously.

If all the result sets have been processed, SQLNextResult() returns SQL_NO_DATA_FOUND.

If SQLFreeStmt() is called with the SQL_CLOSE or SQL_DROP option, all pending result sets on this statement handle are discarded.

Return codes

  • SQL_SUCCESS
  • SQL_SUCCESS_WITH_INFO
  • SQL_ERROR
  • SQL_INVALID_HANDLE
  • SQL_NO_DATA_FOUND
