Opening the Hibernate console
- Open the Persistence tool window ( or Persistence in the lower part of the left-hand tool window bar).
- Expand the Hibernate facet node.
- Select the session factory for which you want to open the console or any node within that session factory.
- Do one of the following:
When you run your first query (), the output pane opens above the input pane. Basically, this is the log of operations performed in the console.
If your query retrieves data (e.g.
also the Result pane opens showing the retrieved data in table format.
Viewing and modifying the console settings
Before actually starting to use a console, you may want to take a look at the console settings and adjust them to your needs.
- Query results are to be shown (the Data View section).
- Retrieved table data are converted into CSV, TSV and other formats (the Data Extractors section).
Note that the settings in the Console section are irrelevant to the Hibernate console. For more information, see Database.
Composing HQL queries
When composing your queries in the input pane, use auto-completion and highlighting of HQL keywords, and object and property names.
Navigating to the declaration of a class or field
When composing a query, it's sometimes useful to take a look at the declaration of a class or field for an object or property referenced in the input pane. To navigate to the corresponding declaration, do one of the following:
- Place the cursor within the name of the object or property of interest. Then use Ctrl+B. (Alternatively, you can use from the main menu.)
- Press and hold the Ctrl key, and point to the name of interest. When the text turns into a hyperlink, click the hyperlink.
As a result, the necessary source file opens in the editor and the cursor is placed within the declaration of the corresponding class or the getter method for the corresponding field.
Running a query
To run the current query, do one of the following:
Running parameterized queries
Your queries can contain parameters, however, by the time you run such queries the values of the parameters must be specified. There are the following ways of specifying the parameter values:
Click on the toolbar or press
Ctrl+Enter to run the query.
In the dialog that opens, specify the parameter values and click OK.
( To start editing a value, switch to the corresponding table cell and start typing. To indicate that you have finished editing a value, press Enter or switch to a different cell. To quit the editing mode and restore an initial value, press Escape. )
- Alternatively, you can open the Parameters pane ( on the toolbar) and specify the corresponding values there. (The values are edited in the same way as in the corresponding dialog.) Then run the query ( on the toolbar or Ctrl+Enter).
Running auto-memorized queries
As you run HQL queries in the console, IntelliJ IDEA memorizes them. So, at a later time, you can view the queries you have already run and, if necessary, run them again.
There are two panes in the History dialog. The left-hand pane shows the list of the queries that you have run. For "long" queries, only their beginnings are shown. When you select a query in this pane, the overall query is shown in the pane to the right.
You can filter the information: just start typing. As a result, only the queries that contain the typed text will be shown.
- Double-click the query to be copied.
- Select the query of interest and press Enter.
- Select the query and click OK.
(Once the query is in the input pane, you can run it straight away.)
Terminating query execution
To terminate execution of the current query, do one of the following:
Generating SQL statements and DDL SQL scripts
You can generate SQL statements for your HQL queries and DDL SQL scripts for your session factory:
- To generate an SQL equivalent of the current query, do one of the following:
To generate DDL SQL statements
DROP TABLE) for all the objects (classes) associated with the corresponding session factory, do one of the following:
The generated SQL statements are shown in the output pane.
Hiding or showing the Result pane toolbar
To hide or show the toolbar of the Result pane:
Pinning the Result tab
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. To do that:
See also, Show query results in new tab.
Navigating through subsets of rows
If only a subset of the rows that satisfy the query is currently shown, to switch between the subsets, use:
See also, Making all rows visible simultaneously.
Making all rows visible simultaneously
If you want all the rows that satisfy the query to be shown simultaneously:
- Click on the toolbar of the Hibernate Console tool window.
On the Database page that opens,
0in the Result set page size field, and click OK.
- Click or press Ctrl+F5 to refresh the table view.
Navigating to a specified row
To switch to a row with a specified number:
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: . 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: . 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: .
Finally, when you click the cell for the third time, the initial state is resorted. That is, sorting by the corresponding column is canceled: .
To reorder columns, use drag-and-drop for the corresponding cells in the header row.
See also, Restoring the initial table view.
Hiding and showing columns
To show a hidden column:
Do one of the following:
In the list that appears, the names of hidden columns are shown struck through.
- Select (highlight) the column name of interest and press Space.
- Press Enter or Escape to close the list.
Restoring the initial table view
Click on the toolbar to restore the initial table view after reordering or hiding the columns, or sorting the data. As a result, the data, generally, becomes unsorted, the columns appear in the order they are defined in the corresponding query, and all the columns are shown.
Using the Structure view to sort data, and hide and show columns
When working with the Result pane, the table structure view is available as the corresponding popup.
The structure view shows the list of all the columns and lets you sort the data as well as hide and show the columns.
To open the structure popup, do one of the following:
In the popup, select the column of interest and do one of the following:
- To sort the data by this column in the ascending order, press Shift+Alt+Up.
- To sort the data in the descending order, press Shift+Alt+Down.
- To cancel sorting by this column, press Ctrl+Shift+Alt+Backspace.
- To hide the column (or show a hidden column), press Space. (The names of hidden columns are shown struck through.)
The shortcuts for sorting table data (Shift+Alt+Up, Shift+Alt+Down and Ctrl+Shift+Alt+Backspace) can be used in the Result pane without opening the structure view.
Copying a table to the clipboard or saving table in a file
- Do one of the following:
- If you are saving the table in a file, specify the file name and location.
If only a subset of rows is currently shown, all the rows that satisfy the corresponding query are copied to the clipboard or saved in a file anyway.
See also, Changing table output format.
Changing table output format
Several output formats are available for copying tables to the clipboard or saving them in files. (The output formats, in IntelliJ IDEA are called data extractors.)
To make a different extractor active or to create a new extractor:
- Do one of the following:
Do one of the following:
- To make a different extractor active, click the name of the desired extractor.
- To create a new extractor, or to view or modify the settings for an existing extractor, click Configure Extractors. As a result, the CSV Formats Dialog will open.
Saving a LOB in a file
If a cell contains a binary large object (a.k.a. BLOB or LOB), you can save such a LOB in a file.
Updating the table view
To refresh the table view, do one of the following:
- Click on the toolbar.
- Right-click the table and select Reload Page from the context menu.
- Press Ctrl+F5.
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.
Viewing the query
To see the query that was used to generate the table:
Click View Query on the toolbar.
If necessary, you can select the query text and copy it to the clipboard (Ctrl+C).
To close the pane where the query is shown, press Escape.
Closing a console
To close a console, do one of the following:
