For the JPA console to be fully functional, you should associate your persistence unit with the corresponding data source, see Associating persistence units and session factories with data sources.
Opening the JPA console
Open the Persistence tool window (e.g. ).
Expand the JPA facet node.
Select the persistence unit for which you want to open the console or any node within that persistence unit.
Do one of the following:
Click on the title bar.
Select Console from the context menu.
If asked to choose the console, select JPA Console.
The input pane of a query console opens as a separate editor tab. The input pane is where you compose your SQL statements.
When you execute a statement, the Services tool window opens. The Services tool window displays available connection sessions, Output and Result tabs. For more information about the Services tool windows, see Services tool window.
If the executed statement retrieves data (for example,
SELECT), results are displayed in the Result tab that has a title of a qualified table name. For more information about creating custom titles for result tabs, see Use custom titles for tabs with results.
Before execution of a parametrized statement, you see the Parameters window where you can specify values for the parameters.
Running the console with custom JVM options
The JPA console is a Java process. If necessary, you can start it with custom JVM options:
Create an Application run configuration:.
In the VM options field, specify the options that you want to pass to the JVM at its start. The rest of the run configuration settings don't matter and you don't need to specify them.
When starting the console, IntelliJ IDEA will now display an additional Configurations popup with the following options:
<default>. This option corresponds to an ordinary way of starting the console.
<YourRunConfigurationName>. Select this option to start the console with the VM options you have specified.
Modify console settings
Open a console and click the Open Database Settings icon ().
Composing JPQL queries
When composing your queries in the input pane, use auto-completion and highlighting of JPQL 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 usefrom 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:
Click on the toolbar.
Running parameterized queries
If you have parameters in your statement, you must specify the values of the parameters before you execute the statement.
To execute a parameterized statement, click the Execute button on the toolbar and enter values in the second column. Alternatively, to open the Parameters dialog, click the View Parameters button .
Running auto-memorized queries
IntelliJ IDEA stores history of all statements that you have run.
To open the History dialog, click or press Ctrl+Alt+E.
To filter information, start typing your search query.
To paste the query from the History dialog to the console, double-click the query in the left pane of the History dialog.
To delete a record from history, select the record and press Delete.
Terminating query execution
To terminate execution of the current statement or statements, click the Disconnect button or press Ctrl+F2.
Generating SQL statements and DDL SQL scripts
You can generate SQL statements for your JPQL queries and DDL SQL scripts for your persistence unit:
- To generate an SQL equivalent of the current query, do one of the following:
Click on the toolbar.
- To generate DDL SQL statements
DROP TABLEfor all the objects (classes) associated with the corresponding persistence unit, do one of the following:
Click on the toolbar and select Generate DDL.
The generated SQL statements are shown in the output pane.
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.
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).
To change this limit, open settings settings Ctrl+Alt+S and navigate to Limit page size to field, specify a new number. To disable the limitation, clear the Limit page size to checkbox.. In the
Also, you can click the Change page size list in the editor, and select a predefined value.
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
To sort table data in a column, click the corresponding cell in the header row. You can click several header row cells to sort table data on multiple columns.
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.
Hiding and showing columns
To hide a column, right-click the corresponding header cell and select Hide column.
To show a hidden column:
- Do one of the following:
Right-click any of the cells in the header row and select Column List.
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 in which they were defined initially, 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:
Right-click a cell in the table header row and select Column List.
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.
Export a table to a file
Open a table or a result set, click the Export Data icon () and click Export To File.
Export a table to a clipboard
On the toolbar, click the Export Data icon () and select Copy To Clipboard.
Configure data output format and options
You can configure how extracted data is converted into text using predefined output formats, customized formats, and scripts. To configure the output for extracted data, right-click any cell in the table and select Choose Data Extractor.
In this menu, you can select the output format (for example, as SQL
INSERT statements, HTML table, or in CSV format) or a script that converts data into a specific format.
Additionally, you can configure the following parameters:
Configure CSV Formats. Opens the CSV Formats dialog that you can use to manage your delimiter-separated values formats (for example, CSV or TSV).
Go to Scripts Directory. Opens a directory with the scripts that convert table data into various output formats.
Saving a LOB in a file
You can save a binary large object (BLOB or LOB) from a cell into a file.
Right-click the cell that contains the LOB and select Save LOB.
In the save dialog, specify the name and location of the file and click OK.
Reload data for the table view
You need to reload data for the table view if you want to synchronize the data that you see in the editor with the contents of the database. Or, when you want to apply the page size limit setting after its change.
Click the Reload Page icon on the toolbar.
Right-click the table and select Reload Page from the context menu.
View the query that generated the result set
To see the query that was used to generate the result table, click the Show Options Menu icon () and select View Query. If necessary, you can select the query text and copy it to the clipboard by pressing Ctrl+C.
To close the pane where the query is shown, press Escape.
