Process Results (ODBC)
Retrieve result set information.
If bound columns are used, for each column you want to bind to, call SQLBindCol to bind a program buffer to the column.
For each row in the result set:
Call SQLFetch to get the next row.
If bound columns are used, use the data now available in the bound column buffers.
If unbound columns are used, call SQLGetData one or more times to get the data for unbound columns after the last bound column. Calls to SQLGetData should be in increasing order of column number.
Call SQLGetData multiple times to get data from a text or image column.
If it returns SQL_SUCCESS, another result set is available.
If it returns SQL_NO_DATA, no more result sets are available.
If it returns SQL_SUCCESS_WITH_INFO or SQL_ERROR, call SQLGetDiagRec to determine if the output from a PRINT or RAISERROR statement is available.
If bound statement parameters are used for output parameters or the return value of a stored procedure, use the data now available in the bound parameter buffers. Also, when bound parameters are used, each call to SQLExecute or SQLExecDirect will have executed the SQL statement S times, where S is the number of elements in the array of bound parameters. This means that there will be S sets of results to process, where each set of results comprises all of the result sets, output parameters, and return codes usually returned by a single execution of the SQL statement.
When a result set contains compute rows, each compute row is made available as a separate result set. These compute result sets are interspersed within the normal rows and break normal rows into multiple result sets.
Optionally, call SQLFreeStmt with SQL_UNBIND to release any bound column buffers.
If another result set is available, go to Step 1.
