PyCharm 2016.3 Help

Table Editor

From the Database tool window (for any table within a DB data source):

  • /help/img/idea/2016.3/DataTables.png on the toolbar (if the toolbar is not currently hidden)
  • Table Editor from the context menu
  • F4

Use the Table Editor to manipulate the table data, and to perform other, associated tasks.

There are two tabs in the Table Editor:

  • Data. On this tab, the table you are working with is shown.
  • DDL. Initially, the CREATE TABLE statement used to create the table is shown on this tab. You can edit the statement and then run it (/help/img/idea/2016.3/run.png on the toolbar or Ctrl+Shift+F10). Use /help/img/idea/2016.3/refresh.png or Ctrl+F5 to regenerate the CREATE TABLE statement for the current state of the table in the database.

Below, the features of the Data tab are discussed.

Toolbar controls, context menu commands for data cells and keyboard shortcuts

Most of the functions on the Data tab are accessed by means of controls on the toolbar, context menu commands for the data cells, and associated keyboard shortcuts.

ItemShortcutDescription
/help/img/idea/2016.3/dataSourceTableEditorFirstPage.png, /help/img/idea/2016.3/dataSourceTableEditorPreviousPage.png, /help/img/idea/2016.3/dataSourceTableEditorNextPage.png and /help/img/idea/2016.3/dataSourceTableEditorLastPage.png These icons and corresponding commands are for switching between the result set pages, i.e. the pages that show the table data.

A fixed number of rows shown simultaneously is referred to as a result set page. If this number is less than the number of rows in the table, only a subset of all the rows is shown at a time.

In such cases, you can use /help/img/idea/2016.3/dataSourceTableEditorFirstPage.png, /help/img/idea/2016.3/dataSourceTableEditorPreviousPage.png, /help/img/idea/2016.3/dataSourceTableEditorNextPage.png and /help/img/idea/2016.3/dataSourceTableEditorLastPage.png to switch between the subsets. (If all the rows are currently shown, these icons and the corresponding commands are inactive.)

The result set page size is set on the Database page of the Settings dialog.

/help/img/idea/2016.3/dataSourceTableEditorFirstPage.png First Page Use this icon or command to switch to the first of the result set pages to see the first series of rows.
/help/img/idea/2016.3/dataSourceTableEditorPreviousPage.png Previous Page Ctrl+Alt+Up Use this icon, command or shortcut to switch to the previous result set page to see the previous series of rows.
/help/img/idea/2016.3/dataSourceTableEditorNextPage.png Next Page Ctrl+Alt+Down Use this icon, command or shortcut to switch to the next result set page to see the next series of rows.
/help/img/idea/2016.3/dataSourceTableEditorLastPage.png Last Page Use this icon or command to switch to the last of the result set pages to see the last series of rows.
/help/img/idea/2016.3/refresh.png Reload Page Ctrl+F5 Use this icon, command or shortcut to refresh the current table view. Use this function to:
  • Synchronize the data shown with the actual contents of the database.
  • Apply the Result set page size setting after its change.
/help/img/idea/2016.3/DBAddRow.png Add New Row Alt+Insert Use this icon, command or shortcut to add a new row to the table.

Complete entering a value into a cell by pressing Enter. To save the new row, select Submit New Row from the context menu or press Ctrl+Enter.

See also, Adding a row.

/help/img/idea/2016.3/DBDeleteRows.png Delete Selected Rows Ctrl+Y Use this icon, command or shortcut to delete the selected row or rows.

Rows are selected by clicking the cells in the column where the row numbers are shown. To select more than one row, use mouse clicks in combination with the Ctrl key.

Auto-commit Use this check box to turn the autocommit mode for the database connection on or off.

In the autocommit mode, each SQL statement is executed in its own transaction that is implicitly committed. Consequently, the SQL statements executed in this mode cannot be rolled back.

(Each change of a value in the table, or adding or deleting a row - when submitted to the database server - results in executing an SQL statement.)

If the autocommit mode is off, transactions are committed or rolled back explicitly by means of the commit or rollback command. Each commit or rollback starts a new transaction which provides grouping for a series of subsequent SQL statements.

In this case, the data manipulations in the transaction scope are committed or rolled back all at once when the transaction is committed or rolled back.

/help/img/idea/2016.3/DBCommit.png Commit If the autocommit mode is off, use this icon or command to commit the current transaction.
/help/img/idea/2016.3/DBRollback.png Rollback If the autocommit mode is off, use this icon or command to roll back the current transaction.
/help/img/idea/2016.3/stop.gif Cancel Query Ctrl+F2 Use this icon or shortcut to terminate execution of the current query.
/help/img/idea/2016.3/DataExtractorButton.png Data Extractor Use this button or command to open a menu in which you can select an output format for your data. The Configure CSV Formats command in that menu opens the CSV Formats Dialog that lets you manage the delimiter-separated values formats (e.g. CSV, TSV).
View Query Use this button to view the query which was used to generate the current table view. To close the pane where the query is shown, press Escape.
/help/img/idea/2016.3/IconDBToolbarMenu.png This icon provides access to the following commands:
  • Transpose. Use this command to turn the transposed table view on or off. (In the transposed view, the rows and columns are interchanged. So, the rows are shown as columns and vice versa.)
  • Reset View. Use this command to restore the initial table view after reordering or hiding the columns, or sorting the data.
  • Sort via ORDER BY. Use this command to turn the corresponding option on or off.

    If the Sort via ORDER BY option is on, all the sorting operations that you perform are reflected in the corresponding SELECT statement (an ORDER BY clause is added or modified) which is executed immediately. As a result, the data for the whole table is sorted by the corresponding database system.

    Don't turn this option on if you want to keep interactions with the database to a minimum (e.g. when the table is very big or the database connection is "slow").

    If this option is off, the data is sorted "locally" by PyCharm and only for the rows currently shown.

  • Row Filter. Use this command to show or hide the box in which you can specify filtering conditions for your table.
  • Settings. Use this command to open the Database page of the Settings dialog to view or edit the settings for the Database console, the Table Editor and the Database tool window.
/help/img/idea/2016.3/TableEditorFilterBox.png Specify filtering conditions for the table. (If the filter box is not currently shown, click /help/img/idea/2016.3/IconDBToolbarMenu.png on the toolbar and select Row Filter.)

The filtering conditions are specified as in a WHERE clause but without the word WHERE, e. g. name LIKE 'a%' AND notes LIKE '%metal%'. Within the LIKE expressions, the SQL wildcards can be used: the percent sign (%) for zero or more characters and underscore (_) for a single character.

/help/img/idea/2016.3/TableEditorFilteredTable.png

To apply the conditions currently specified in the box, press Enter. To cancel filtering, click /help/img/idea/2016.3/clear.png, or delete the contents of the filter box and press Enter.

To reapply a memorized filter, click /help/img/idea/2016.3/find1.png and select the filter in the list. See also, Filter history size.

/help/img/idea/2016.3/DBFilterHistorySize2.png
Clone RowCtrl+DUse this command or shortcut to create a copy of the selected row.
Edit F2 Use this command or shortcut to start editing a value in the selected cell or cells. (Alternatively, you can double-click the cell or simply start typing.)

To enter the modified value, press Enter. To cancel editing, press Escape.

See also, Modifying cell contents and Modifying values in a number of cells at once.

SubmitCtrl+Enter Submit the changes to the database server. See Submitting and reverting changes.
RevertCtrl+Z Revert the changes within the selection. See Submitting and reverting changes.
Quick Documentation Ctrl+Q Use this command or shortcut to open the quick documentation view. To close the view, press Escape. For more information, see Using the quick documentation view.
Go To | Row Ctrl+G Use this command or shortcut to switch to a specified row. In the dialog that opens, specify the row number to go to.
Go To | Related Data F4 Use this command or shortcut to switch to a related record. The command options are a combination of those for Go To | Referenced Data and Go To | Referencing Data.

The command is not available if there are no related records.

Go To | Referenced Data Ctrl+B Use this command or shortcut to switch to a record that the current record references. If more than one record is referenced, select the target record in the pop-up that appears.

The command is not available if there are no referenced records.

Go To | Referencing Data Alt+F7 Use this command or shortcut to see the records that reference the current record. In the pop-up that appears there are two categories for the target records:
  • First Referencing Row. All the rows in the corresponding table will be shown and the first of the rows that references the current row will be selected.
  • All Referencing Rows. Only the rows that reference the current row will be shown.

The command is not available if there are no records that reference the current one.

Filter by Use this command to access quick filtering options. The options include those for the current column name and depend on the value in the current cell.
CopyCtrl+C Copy the selection onto the clipboard. See also, Copying and pasting data: data types are converted if necessary.
PasteCtrl+V Paste the contents of the clipboard into the table. See also, Copying and pasting data: data types are converted if necessary.
/help/img/idea/2016.3/downloadArtifacts.png Dump Data | To Clipboard Use this command to copy the table data onto the clipboard.
/help/img/idea/2016.3/downloadArtifacts.png Dump Data | To File Use this command to save the table data in a file. In the dialog that opens, specify the location and name of the file.
Save LOB Use this command to save the large object (LOB) currently selected in the table in a file.

Using the table header row: sorting data, reordering and hiding columns

Use the cells in the header row (i.e. the row where column names are shown) for:

You can sort table data by any of the columns by clicking the cells in the header row.

Each cell in this row has a sorting marker in the right-hand part and, initially, a cell may look something like this: /help/img/idea/2016.3/TableEditorHeaderCellUnsorted.png. The sorting marker in this case indicates that the data is not sorted by this column.

If you click the cell once, the data is sorted by the corresponding column in the ascending order. This is indicated by the sorting marker appearance: /help/img/idea/2016.3/TableEditorHeaderCellSortAsc.png. 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.)

When you click the cell for the second time, the data is sorted in the descending order. Here is how the sorting marker indicates this order: /help/img/idea/2016.3/TableEditorHeaderCellSortDesc.png.

Finally, when you click the cell for the third time, the initial state is resorted. That is, sorting by the corresponding column is canceled: /help/img/idea/2016.3/TableEditorHeaderCellUnsorted.png.

Here is an example of a table where data are sorted by two of its columns.

/help/img/idea/2016.3/TableEditorSortedTable.png

To restore the initial "unsorted" state for the table, click /help/img/idea/2016.3/IconDBToolbarMenu.png and select Reset View. See also, Sort via ORDER BY.

To reorder columns, use drag-and-drop for the corresponding cells in the header row. To restore the initial order of columns, click /help/img/idea/2016.3/IconDBToolbarMenu.png and select Reset View.

/help/img/idea/2016.3/TableEditorReorderColumns.png

To hide a column, right-click the corresponding header cell and select Hide column.

To show a hidden column:

  1. Do one of the following:
    • Right-click any of the cells in the header row and select Column List.
    • Press Ctrl+F12.

    In the list that appears, the names of hidden columns are shown struck through.

    /help/img/idea/2016.3/TableResultPaneHideColumn.png
  2. Select (highlight) the column name of interest and press Space.
  3. Press Enter or Escape to close the list.

To show all the columns, click /help/img/idea/2016.3/IconDBToolbarMenu.png and select Reset View.
