Hi,

I use the following code:

String SQL = "PARAMETERS name Text(255);"
SQL += "SELECT ID FROM tblClient WHERE clientName = name";
qry->SQL->Clear();
qry->SQL->Add(SQL);
qry->Parameters->ParamByName("name") = "Test";

qry->ExecSQL();

When I execute this code I get the following error:
Parameter 'name' not found

What I am doing wrong?

Thanks in advance

ParamByName recognizes parameters in form :paramName - select ID from
tblClient where clientName = :name. Try qry->Parameters->Refresh() after
assigning SQL, you may want to set ParamCheck = false if you do not use
:paramName notation. BTW, your syntax is for MS Jet (MS Access) only.
