Base on help CPLEX to concatenate string you need to use + , I write  (to get ed1) - should be simple!

string tool_id = "ed"+"1";

I get the error "Operator not available for string + string." - It should be simple!

I got an answer that it is the scripting blocks (thanks for the answer) . But I need it for parameter on SQL query in the modeling part?

Thanks for the answer!
