Suggestion about one new component.

Post by banita » Wed 12 Aug 2009 13:41

Sometimes I need component like 'TPSQLDirectQuery' from MicroOLAP PostgresDAC but not only for postgresql.

description:
"TPSQLDirectQuery component is intended for high-speed (2-3 times faster than with using of TPSQLQuery component) data fetching."

"TPSQLDirectQuery allows to execute SQL queries and retrieve resultsets with very high performance. Meanwhile, it is not TDataset-compatible. This means that it can't be assigned to TDatasource.Dataset property and you can't use it with visual DB-controls. TPSQLDirectQuery is usually used in tasks where data require some processing without displaying it with/within visual DB-controls."

Sometimes I present my data in ListView control, so that component will be very useful for me.

sory for my english.

UniDAC has TUniSQL component for direct SQL execution. But this component does not retrieve resultset.

You can use TUniQuery in your application. The performance difference between TUniQuery and a "direct" component will not be significant (about millisecond). Probably user of your application will not notice any differences.
