SQLFetch

Function

SQLFetch advances the cursor to the next row of the result set and retrieves any bound columns.

Prototype

1
SQLRETURN SQLFetch(SQLHSTMT    StatementHandle);

Parameter

Table 1 SQLFetch parameters

Keyword

Description

StatementHandle

Statement handle, obtained from SQLAllocHandle.

Return Values

  • SQL_SUCCESS indicates that the call succeeded.
  • SQL_SUCCESS_WITH_INFO indicates some warning information is displayed.
  • SQL_ERROR indicates major errors, such as memory allocation and connection failures.
  • SQL_NO_DATA indicates that the SQL statement does not return a result set.
  • SQL_INVALID_HANDLE indicates that invalid handles were called. Values returned by other APIs are similar to the preceding values.
  • SQL_STILL_EXECUTING indicates that the statement is being executed.

Precautions

If SQLFetch returns SQL_ERROR or SQL_SUCCESS_WITH_INFO, the application can then call SQLGetDiagRec, set HandleType and Handle to SQL_HANDLE_STMT and StatementHandle, and obtain the SQLSTATE value. The SQLSTATE value provides the detailed function calling information.
