Working with Query Results
When you run a query in the console, you receive results in the table format. Each statement appears in a separate tab in the Database Console tool window. For example, if you have two SELECT statements in the query, you will see two tabs in the tool window.
Open a new tab for each query
By default, RubyMine updates the same tab with results each time you run a query. You can change this behavior and create a tab each time you run a query.
In the IDE settings (Ctrl+Alt+S), go to.
Select the Open results in new tab checkbox and click OK.
Edit values in the result set
In the result set, click a cell value that you want to edit.
Specify a new value and press Enter.
To submit changes to a database, click the Submit icon (), or press Ctrl+Enter.
Export to a file
Right-click a, select.
Right-click a query, click Execute to File and select the file type that you want to use for export (for example, Comma-separated (CSV)).
On the toolbar, click the Dump Data icon () and select To File.
Export to a clipboard
Select data in the result set or in the editor and press Ctrl+C.
On the toolbar, click the Dump Data icon () and select To Clipboard.
Compare two result sets
Select a result set.
Click the Compare with icon (), and select another result set.
If needed, change a value of the Tolerance parameter in the comparison dialog. The Tolerance parameter defines a maximum number of differences that are allowed between two result sets. For example, if you want to consider two rows as equal if their data differs in a single column, enter
1in the Tolerance field.
Pin the tab with query results
If one and the same tab is used to show your query results, and you get the result that you want to keep, you can pin the tab to the tool window. Do one of the following:
Right-click the tab and select Pin Active Tab.
Click on the toolbar.
Navigate between subsets of rows
Depending on the value of the Limit page size to parameter, the result set might be divided into several pages. For example, you set the Limit page size to parameter to 100, but your query returned 200 rows. You will have two pages of rows, with 100 rows on each page. To navigate between pages, use the following controls:
: Navigates to the first page of the result set.
: Navigates to the previous page of the result set. ( Ctrl+Alt+Up )
: Navigates to the next page of the result set. ( Ctrl+Alt+Down )
: Navigates to the last page of the result set.
Set a number of rows in the result set
By default, when you issue a query, the number of returned rows is limited to 500. This limitation is introduced to avoid an overload (for example, when your SELECT statement returns one million rows).
Go to Settings/Preferences (Ctrl+Alt+S) and navigate to .
Specify a new number in the Limit page size to field. To disable the limitation, clear the Limit page size to checkbox.
Go to the specified row
To navigate to a row with a specified number, right-click the table and select Go to row dialog, specify the row number and click OK.(Ctrl+G). In the
Navigate to a related object
You can retrieve rows from the table for the selected object, and move the focus to the object. For example, select a field in the project tree and press Ctrl+Alt+B. The focus moves to the corresponding column in the new tab.
To navigate to the object in the result set, select an object and go to Navigate | Related Symbol (Ctrl+Alt+B).
Navigate between related data
You can navigate between different types of related data:
Referenced data: data that is referenced by the current object.
Referencing data: data that is referencing the current object.
Right-click the column in the table and navigate to Go To | Referenced Data (Ctrl+B) or (Ctrl+Alt+B).
If the Choose target popup appears, select the table and what rows to show:
First Referencing Row: all rows in the table. The first row that references the current row is selected.
Referencing Rows Only: only rows that reference the current row.
To sort table data in a column, click the cell in the header row.
Indicates that the data is not sorted in this column. The initial state of the sorting marker.
The data is sorted in the ascending order. The number to the right of the marker (1 on the picture) is the sorting level. You can sort by more than one column. In such cases, different columns will have different sorting levels.
The data is sorted in the descending order.
To reorder columns, use drag-and-drop for the corresponding cells in the header row.
To hide a column, right-click the corresponding header cell and select Hide column.
Alternatively, you can right-click any of the cells in the header row and select Column List (Ctrl+F12). In the Column List window, select a column name and press Space. You can hide all columns. To search through the column list, just start typing a column name in the Column List window.
Select the hidden column (a strikethrough column name) and press Space.
Reset the initial table view
Click the settings icon () and select Reset View. As a result, the data becomes unsorted, the columns appear in the order they were defined initially, and all the columns are shown.
Operations with columns in the structure view
The structure view displays you a list of all the columns in the selected table. The structure view is available in the Structure tool window ( ) or in the popup window (Ctrl+F12).
Sort the data in the ascending (Shift+Alt+Up) or the descending order (Shift+Alt+Down).
Reset the state of sorting (Ctrl+Shift+Alt+Backspace )
Hide a column or show a hidden column (Space). The names of hidden columns are shown struck-through.
Using the quick documentation view
The quick documentation view provides details about values in the selected cell or cells. For example, if a cell contains long text, you will see the whole text. If a cell contains an image, you will see a preview of the image. Also, you can see records that are referenced in the current record as well as the records that reference the current one.
If a cell contains long text, you will see the whole text.
If a cell contains an image, you will see a preview of the image.
The quick documentation view for records displays records that are referenced in the current record and records that reference the current one.
You can switch to the transposed view. In the transposed view, rows and columns are interchanged.
To switch to the transposed view, click Transposed View. For more information about the transposed view in tables, see Transpose a table.§

Submit changes by using database transactions
You can select to commit transactions automatically or manually. To change the commit mode, use the Tx drop-down menu on the toolbar.
If you submit a change to the database server and the commit mode is set to Auto, each change of values, rows, or columns is implicitly committed and cannot be rolled back.
If the commit mode is set to Manual, you can explicitly commit or roll back submitted changes by means of the Commit icon () or the Rollback icon (). Otherwise, select Commit (Ctrl+Shift+Alt+Enter) or Rollback commands from the context menu.
The Tx switch can also be used for selecting the isolation level for the transactions.
Before you submit the changes, you can revert them.
The scope of the revert command is defined by the current selection in a table: the command is applied only to the changes within the selection. So you can revert an individual change, a group of changes or all the changes. If nothing is currently selected, the revert command is applied to the whole table.
To revert non-submitted changes, select and right-click a cell or a number of cells. Select Revert Selected (Ctrl+Alt+Z).
You can compare the current table with any other table that is open in a data editor or shown in the Database Console tool window.
