ADO Query or ADOCommand Error

[Ginka]

Query->Close();
Query->SQL->Clear();
Query->SQL->Add("SELECT *");
Query->SQL->Add("INTO MyTable");
Query->SQL->Add("FROM OriginalTable");
Query->ExecSQL();

It doesn't work!!

Also I put the SQL code into a ADOCommand
if I double click the command in design time it works (put the query into MyTable), but if I execute the command in run time it doesn't work

Why??!!!!!!

I've used ADO only in a limited context so take my advice for what's its worth (probably useless .) My understanding is a query must return a record set. If is does not, you get an error.

If you want to execute a SQL statement that does not return a record set you have to use the command set. Having said that, I notice that in the book it says you can get around this via a try...catch statement and catch the ENoResultSet exception.

I've not used the ADOCommand so I can't say how it works. Are you getting a specific error or does the command just fail?

ExecSQL() only works with commands that don't return a result set eg. update, delete, etc
If you are using a statement that returns a result set (eg select), you must use Open() instead of ExecSQL()

The same applies to stored procedures (Open()/ExecProc())

Hope that helps
