Example #1 mssql_min_error_severity() example
<?php
// Connect to MSSQL and select the database
mssql_connect('KALLESPC\SQLEXPRESS', 'sa', 'phpfi');
mssql_select_db('php');
// Set the minimum error severity to not include SQL
// syntax errors by setting it to something greater than
// or equal to 1.
mssql_min_error_severity(1);
// Send a query we know that will cause an syntax error, in
// this case we use the MySQL quote signs instead of wrapping
// square brackets around the field and table names.
$query = mssql_query('SELECT `syntax`, `error` FROM `MSSQL`');
if (!$query) {
// Custom error handler ...
}
?>
If you have not worked with MS SQL, severity is based on 5 levels.
Level 0:
The code contains a genuine error, and if executed, may not run as expected. For example, a syntax error or a reference to a non-existent method will cause a Level 0 error.
Level 1:
The code is syntactically correct, and has some defined meaning, but it may not be what the programmer was expecting. For example, a statement with no side effects such as x+1 will generate a Level 1 warning.
Level 2:
The code is correct but may cause problems in the future. For example, using deprecated features will generate a Level 2 warning.
Level 3:
The code is correct but may result in bad performance. For example, if type inferencing fails for a variable, a Level 3 warning will be issued.
Level 4:
The code is correct but there may be a better way to accomplish the same thing. For example, using a non-Common Language Specification (CLS) compliant method signature will generate a Level 4 warning.
