SQLExecute

Description

If a statement contains a parameter marker, the SQLExecute function uses the current value of the parameter marker to execute a prepared SQL statement.

Prototype

1
 
SQLRETURN SQLExecute(SQLHSTMT    StatementHandle);

Parameters

Table 1 SQLExecute parameter

Keyword

Description

StatementHandle

Statement handle to be executed.

Return Values

  • 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.
