function DriverSpecificSyntaxTestBase::testAllowSquareBrackets

Tests allowing square brackets in queries.

This method should be overridden if the SQL syntax of the test queries is not compatible with a non-core database driver. For example, the unquoted 'name' identifier in Oracle is a reserved keyword that would let the test query fail.
