From the TSQLQuery.ExecSQL documentation:

ExecDirect indicates that the query does not need to be prepared before it is executed. This parameter can be set to true if the query does not include any parameters.

So if the code uses

SQLQuery2.ExecSQL(true);

this means that there will be no support for parameters.

But because you use parameters, just use

SQLQuery2.ExecSQL;

and also remove the quotes around parameters.
