That's right, you must inspect feedback codes to determine the success or failure of each and every SQL statement.

One way to deal with SQL states and codes is with 'whenever' SQL statements.  These are pre-processor directive that can relieve the burden of inspecting feedback for specific state- and code-value, like -901 in your example.  Unfortunately they are GOTO-based and so may not smoothly integrate with your beautifully and rigorously structured-programming coding style.
