The TQSqlSelectCursor class provides browsing of general SQL
SELECT statements.
< p >
< p > TQSqlSelectCursor is a convenience class that makes it possible to
display result sets from general SQL < tt > SELECT< / tt > statements in
data-aware TQt widgets. TQSqlSelectCursor is read-only and does not
support < tt > INSERT< / tt > , < tt > UPDATE< / tt > or < tt > DELETE< / tt > operations.
< p > Pass the query in at construction time, or use the
< a href = "tqsqlquery.html#exec" > TQSqlSelectCursor::exec< / a > () function.
< p > Example:
< pre >
...
TQSqlSelectCursor* cur = new TQSqlSelectCursor( "SELECT id, firstname, lastname FROM author" );
< a href = "tqdatatable.html" > TQDataTable< / a > * table = new < a href = "tqdatatable.html" > TQDataTable< / a > ( this );
table-> < a href = "tqdatatable.html#setSqlCursor" > setSqlCursor< / a > ( cur, TRUE, TRUE );
table-> < a href = "tqdatatable.html#refresh" > refresh< / a > ();
...
cur-> < a href = "tqsqlquery.html#exec" > exec< / a > ( "SELECT * FROM books" );
table-> < a href = "tqdatatable.html#refresh" > refresh< / a > ();
