EXEC SQL and errors

Question:
I am using the EXEC SQL command to insert some data into a database on the CommitForm() method of a form, but the data is not showing up in the database. What's wrong?

Answer:
It could be anything, but my suspicion is that the SQL being used with the EXEC SQL command is not working properly.

The EXEC SQL command does not inform an application if an error occurs with the command. The only way you can determine if there has been an error is to use the SqlErrCode() method after the command is executed. The SqlErrCode() will return the error number of the error from the most recent EXEC SQL command, while the SqlErrText() method will return the text of any errors that occurred with the last EXEC SQL command.

If you don't explicitly check the outcome of the EXEC SQL command, you will never know if an error has occurred. Check the outcome — you might have a mistake there.
