SQLFetch

Function

SQLFetch is used to advance the cursor to the next row of the result set and retrieve any bound columns.

Prototype

CSQLRETURN SQLFetch(SQLHSTMT    StatementHandle);

Parameter

Table 1 SQLFetch parameters

Keyword Parameter Description
StatementHandle Statement handle, obtained from SQLAllocHandle.

Return Value

  • SQL_SUCCESS indicates that the call succeeded.
  • SQL_SUCCESS_WITH_INFO indicates that 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. This value may also be returned by other APIs.
  • SQL_STILL_EXECUTING indicates that the statement is being executed.

Precautions

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