Detailed Description

The TQSqlSelectCursor class provides browsing of general SQL SELECT statements.

TQSqlSelectCursor is a convenience class that makes it possible to display result sets from general SQL SELECT statements in data-aware TQt widgets. TQSqlSelectCursor is read-only and does not support INSERT, UPDATE or DELETE operations.

Pass the query in at construction time, or use the TQSqlSelectCursor::exec() function.

Example:

    ...
    TQSqlSelectCursor* cur = new TQSqlSelectCursor( "SELECT id, firstname, lastname FROM author" );
    TQDataTable* table = new TQDataTable( this );
    table->setSqlCursor( cur, TRUE, TRUE );
    table->refresh();
    ...
    cur->exec( "SELECT * FROM books" );
    table->refresh();
    ...
