SQLExecute
Function
SQLExecute is used to execute 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
SQLRETURN SQLExecute(SQLHSTMT StatementHandle);
Parameter
Table 1 SQLExecute parameters
Return Value
- SQL_SUCCESS indicates that the call succeeded.
- SQL_SUCCESS_WITH_INFO indicates that some warning information is displayed.
- SQL_NEED_DATA indicates that parameters provided before executing the SQL statement are insufficient.
- 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 SQLExecute 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.
