Write Queries
On the Write Queries page, you can write and run custom queries with GSQL.  
The Write Query page is horizontally divided into two parts:
Query Editing Panel
Result, Log and Visualization Panel
Query Editing Panel
The Query Editing panel is divided into two sub-panels: the left sub-panel is used to select a query to edit, and the right, larger sub-panel displays the selected query for editing. Here you can edit, save, delete query and/or its draft, install and run the query. The query editor features syntax highlighting customized for the GSQL language.  Also, the query editor performs real-time semantic checking.
Above the query editing pane is a toolbar, with the following buttons, from left to right:  
Expand/Collapse : Expand or collapse the Query Editing panel to or from full page mode. The icon changes depending on whether the panel is currently expanded or collapsed.
Save : Save the current query draft.
Install : Install the query into the database.
Run : Run the query. If the query is not installed, it will run the query in interpreted mode. Note there is performance penalty to run queries in interpreted mode.
Run Configuration: Set the query runtime configurations.
Delete : Delete the selected query and its draft.
Show query endpoint: Show the RESTFul endpoint to execute the query. Only installed queries can see their RESTFul endpoints.
Download: Download the query as a gsql file.
Discard query draft : Delete the selected query draft.
Add Or Edit Query
To create a new query, simply click on the "New GSQL Query" button
at the bottom-right corner of the left sub-panel, and type in the name of the new query in the popup window:  
A query draft will be created with a template:   
To edit an existing query, click on the query name in the list in the left sub panel:   
Save Query Draft
Once you made some changes to the query code and want to save it as a query draft, click on the "save" button
in the toolbar.
Run Query in Interpreted Mode
If you have saved the query and there is no errors in the query, you can run the query in interpreted mode. Click the run query button
. Together with the query execution result, a warning message will appear to notify user of the performance concerns running the query in interpreted mode. To speed up the query performance after you are satisfied with the GSQL query developed in interpreted mode, you can follow the instructions in the next section "Install Query". 
Install Query
If you saved a query, the "install query" button
will be enabled. Click it to install the query. The installation process may take about 1 minute:  
After the installation, the run query button changes from
to
.
Run Query
To run the query, click on the "run" button
in the toolbar. If the query has no parameters, it will run directly and the result will be shown in the Result panel.
If the query requires parameters, the Enter Query Parameters panel will appear. Enter your parameter values and then click the "Run Query" button
at the bottom of the panel. If there are several parameters, you might need to scroll the panel to the bottom to find the Run Query button.
The query will be executed, and the results will be shown in the Result Panel.   
Run Configuration
You can set runtime configurations of the GSQL query by clicking the small 
button to the right of run query button, then a drop-down menu will appear.
Click the "Run configuration" item, and the Run Configuration panel will be opened.
You can set GSQL query timeout here. By default it uses the timeout of TigerGraph configuration (specified by gadmin commands). You can change it by unchecking the "Use default timeout" label, and then set a new timeout:
Click the submit button 
 to apply your changes.
Delete Query
Choose the query you want to delete and click on the "delete" button
. The query will be deleted permanently.
Show Query Endpoint
After finishing writing the GSQL queries and installing the queries, you can access the queries via REST endpoints. By clicking the "show query endpoint" button
, you can see the format of the endpoint to access this query, so that you can integrate the query with your applications.
Download
You can download your query by click 
, or download all your queries as a tarball by click 
 

Delete query draft
You can delete your query draft by clicking ​
.
Install All Queries
If you want to install all queries that you haven't installed yet, you can click "Install all queries" button
in GSQL Queries list. After some verification time, a pop up window listing all queries to be installed will show:
Click INSTALL button, then the listed queries will be installed:
Result Panel
The Result panel shows the result of the last run query. Each query generates up to three types of result: visualized graph, JSON text, or log messages. On the left is a toolbar with buttons for changing the the panel size or for switching to a different type of result. The buttons, from top to bottom, are the following:
menu option
functionality
​
 
Expand/Collapse: Expand or collapse the Result panel. 
​
 
View schema: Show the graph schema.
​
 
Visualize graph result: Show the visual result of the last run query. 
​
 
View JSON result: Show the raw text result in JSON format of the last run query. 
​
 
View logs: Show the log for the last run query.
View schema:
Viewing graph schema makes it more convenient for developers to refer to the schema topology logic and easier to write correct GSQL queries.
Visualize graph result
If the query execution result contains a graph structure, the result will be visualized in this panel as a graph. The panel is the same as the Explore Graph panel. Please refer to the documentation for the Explore Graph panel. The only difference is that each time you run a query, the previous result will be erased. In Explore Graph the results are added incrementally.   
You can switch to the JSON Result panel to see the result in JSON format.
View JSON result
If there is no graph structure in the result, the result will be displayed in this panel as a JSON object.   
You can learn about the JSON format in the GSQL Language documentation , and integrate it with your applications. In this fashion, the TigerGraph system can serve as a backend or embedded graph data service.
View logs
If a query ran successfully, the Query Log message will be "query ran successfully" or something similar. If there was anything wrong when executing your query, such as invalid parameters or runtime errors, an error message will be shown in the Query Log panel:  
Expand Panels
If you just want to focus on developing your query, or want to have more space to view your result, click the Expand button 
 in either the Query Editing panel or the Result panel.
If you expand the Query Editing panel, it looks like this:   
If you expand the Result panel, it looks like this:   
When the panel is expanded, the Expand button becomes the Collapse button
. Clicking it will return the display to the split panel view.
