Column and table names
In the Database Schema Configurator, invalid column names are disabled in the column list table. The tooltip is a reminder of these disabled column names to ensure you clear the state.
The tooltip is similar to: "Cloverleaf does not support special characters, including spaces, for table/column names even though they are supported by the SQL standard syntax."
In table and column names, CIS only supports letters, digits, and underscores.
