To show the record count here, we actually go physically query the database with a row count type query.Īll we know is that the query has finished executing, and that there are rows available to go fetch. We don’t know how many records are in this result set actually. So if I run a query that returns MORE than 50 rows: There’s more than 50 records in this resultset, but we have 50 in the grid to start with. ctrl-enter : executes the current statement (s) F5 : executes the current code as a script ( think SQLPlus) ctrl-space : invokes code insight on demand.
