SQLExecute

Updated at: Jul 15, 2020 GMT+08:00

Function

The SQLExecute function executes a prepared SQL statement using SQLPrepare. The statement is executed using the current value of any application variables that were bound to parameter markers by SQLBindParameter.

Prototype

1
SQLRETURN SQLExecute(SQLHSTMT    StatementHandle);

Parameter

Table 1 SQLExecute parameters

Keyword

Description

StatementHandle

Statement handle to be executed.

Return Values

  • SQL_SUCCESS indicates that the call succeeded.
  • SQL_SUCCESS_WITH_INFO indicates some warning information is displayed.
  • SQL_NEED_DATA indicates insufficient parameters provided before executing the SQL statement.
  • 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 SQLExecute 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.
