Enhanced SQL Support
The SQL Procedural Language feature of the RDM database system allows for a SQL database developer to access full programming constructs purely in SQL. They can create conditional statements, for and while loops, declare and use variables, all while using only SQL. There is even error handling support for custom error situations. Additionally, these statements are compiled and executed on the server-side, greatly improving the performance of the overall system.
SQL triggers are a form of SQL PL that lets the SQL developer create custom events to occur when certain conditions are met in a normal create/insert/update/delete SQL statement. They can be simple things like returning an error if an insert is out of the bounds of a column, or more complicated things, like updating a further table/row if certain conditions are satisfied.
