SQL Query Results Data Grid

Code Editor > SQL Query Results > SQL Query Results Data Grid

Browse the results of an executed SQL query in a dynamic grid with options for viewing, sorting and navigating. There can be multiple results displayed, one per statement executed. Each result set is displayed in a separate tab.

Note:

  • When a result tab is selected, the SQL query statement that generated the result is focused.
  • If the data is LOB, XML or Array then double click on the data cell for more information. For more information, see Viewers: LOB, XML, Array.
  • The Data Grid supports National Language Support (NLS). Display and edit multi byte data.

Edit (Updateable Queries)

Turn ON Updateable in the SQL Editor Toolbar (Code Editor SQL) before you execute the SQL query. The status panel at the bottom of the Code Editor window says "Updateable" if the results can be edited. It says "Read Only" if the results cannot be edited.

  • Right click on the data grid for more options.

Requirements

  • The SELECT statement must be a simple SELECT statement (no joins, subqueries in select clause, calculated fields, group by, having, count(), substr or DISTINCT). If you get an error message such as TOKEN:.(12121,2) then your query does not conform to the restrictions for updateable queries.
  • You must have the appropriate privileges to update the table or view.
