What is SQL Commands?
You can use SQL Commands to create, edit, view, run, and delete SQL commands. A SQL command can contain SQL statements or PL/SQL blocks.
When using SQL Commands, remember the following:
SQL commands created in the Query Builder can be accessed in SQL Commands.
Saved SQL commands must have names unique within a given workspace.
There is no interaction between SQL Commands and SQL Scripts.
You can cut and paste a SQL command from SQL Commands to run in the SQL Script Editor.
Accessing SQL Commands
To access SQL Commands:
Log in to the Workspace home page.
The Workspace home page appears.
To view the SQL Commands home page you can either:
Click SQL Workshop and then SQL Commands to drill-down to the SQL Commands home page.
Click the down arrow on the right side of the SQL Workshop icon to view a drop down menu. Then select the SQL Commands menu option.
Description of the illustration sql_commands.gifNote:
For the purposes of consistency, this document uses the primary navigation path (or drill-down approach) when explaining navigation.
About the SQL Commands Home Page
The SQL Commands home page is divided into two sections: a command editor and a display pane. You use the command editor to execute SQL commands and the display pane to view output, saved command lists, and history lists.
Description of the illustration sql_com_top.gif
The top of the SQL Commands home page features a command editor and the following controls:
Autocommit. If available, click the Autocommit check box to enable autocommit and disable transactional commands. See 'About Transactions in SQL Commands'.
Display. Make a selection from the Display list to specify the number of rows of output to display simultaneously up to a maximum of 100,000. All rows of DBMS Output are displayed regardless of the Display list setting.
Clear Command icon. The Clear Command icon resembles a pencil with an eraser. Use this icon to clear the text in the command editor.
Find Tables icon. The Find Tables icon resembles a flashlight. Click this icon to view tables and views. See 'Using the Find Tables Icon'.
Save. Click the Save button to save the contents of the command editor, or the currently highlighted content to a file. You are prompted to enter a name and an optional description. The command appears in the Saved SQL list. See 'Saving a SQL Command'.
Run. Click the Run button (or press Ctrl+Enter) to run the command in the command editor, or the currently highlighted command in the command editor. See 'Running a SQL Command'.
Selecting a Schema
A schema is a logical container for database objects. To access objects in another schema, make a selection from the Schema list in the upper right side of the page.
Switching to Another SQL Workshop Component
You can navigate to another SQL Workshop component by making a selection from the Component list located on the upper right side of the page:
Object Browser. See 'Managing Database Objects with Object Browser'.
SQL Commands. See 'Using SQL Commands'.
SQL Scripts. See 'Using SQL Scripts'.
Query Builder. See 'Building Queries with Query Builder'.
About the Display Pane
A display pane displays at the bottom of the SQL Commands home page.
Description of the illustration sql_com_bottom.gif
The display pane features five tabs:
Results. Click the Results tab to see the results from the last successfully executed SQL command. Click DBMS Output at the bottom of the displayed results to display lines of DBMS output. This control only appears when there is DBMS output to display. Click Download to export results to a comma-delimited file on your local file system. See 'Viewing Results'.
Explain. Click the Explain tab to examine the execution plan used by the optimizer for statements that make changes to the database. Objects in the output are linked to the Object Browser. Click the linked object to view its properties in the Object Browser. See 'Using Explain Plan'.
Describe. Enter Describe object_name and click Run to display column definitions for a table or view, or specifications for a function or procedure in the Describe tab. Select links in the Describe results to write that information into the command editor. For example, click a table name to add owner.table, click a column name to add the column name, click a procedure or function name to add the object call with parameters, or click a package name to add the package call.
Saved SQL. Click the Saved SQL tab to display a list of all SQL commands saved in the current workspace. Click the command title to load it into the command editor. See 'Using Saved Commands'
History. Click the History tab to list your recently executed commands. Your last 200 executed commands are saved. See 'Using SQL Command History'.
Using the Command Editor
You use the command editor in SQL Commands to execute SQL commands within Application Express.
Topics in this section include:
Running a SQL Command
To execute a SQL Command:
On the Workspace home page, click SQL Workshop and then SQL Commands.
The SQL Commands page appears.
Enter the SQL command you want to run in the command editor.
Click Run (Ctrl+Enter) to execute the command.
Tip:
To execute a specific statement, select the statement you want to run and click Run.The results appear in the Results pane.
To export the resulting report as a comma-delimited file (.csv) file, click the Download link.
About Transactions in SQL Commands
To disable transactional SQL commands in SQL Commands, check the Autocommit check box. Attempting to use any transactional SQL commands such as COMMIT or ROLLBACK when transactional mode is disabled returns an error message.
To enable transactional SQL commands, clear the Autocommit check box. Oracle Application Express verifies that the necessary system resources are available before entering the transactional mode. If resources are unavailable, an error message is displayed.
Transactional mode is a stateful transaction mode where you can, for example, perform an update, select data for review, and COMMIT or ROLLBACK changes. It is implemented using DBMS_JOBS.
Consider the following behavior in transactional mode:
Actions are not committed to the database until you enter an explicit COMMIT command.
Exiting SQL Commands terminates and rolls back the current transaction.
A session timeout terminates and rolls back the current transaction.
Note that the Environment Setting,
SQL Commands Maximum Inactivity in minutes, sets the time before an inactive session times out. The default timeout is 60 minutes. See 'Configuring SQL Workshop' in Oracle Application Express Administration Guide.The CSV Export option is not available.
About Unsupported SQL*Plus Commands
SQL Commands does not support SQL*Plus commands. If you attempt to enter a SQL Command Line command such as SET ECHO or DEFINE in SQL Commands, an error message displays.
About Command Termination
You can terminate a command in SQL Commands using a semicolon (;), a slash (/), or with nothing. Consider the following valid alternatives:
The first example demonstrates the use of a semicolon (;), the second example demonstrates using a slash (/), and the final example demonstrates a command with no termination.
Using Bind Variables
Bind variables are supported. You are prompted to enter values for bind variables during command execution. Bind variables are prefixed with a colon.
For example
In earlier versions of Oracle Application Express, you could check your Workspace ID by running the command:
In this release, run the following SQL command to check your Workspace ID:

Visual Studio Code has a powerful command line interface built-in that lets you control how you launch the editor. You can open files, install extensions, change the display language, and output diagnostics through command-line options (switches).
If you are looking for how to run command-line tools inside VS Code, see the Integrated Terminal.
Command line help
To get an overview of the VS Code command line interface, open a terminal or command prompt and type code --help. You will see the version, usage example, and list of command line options.
Command Tab Plus 1 833
Launching from command line
You can launch VS Code from the command line to quickly open a file, folder, or project. Typically, you open VS Code within the context of a folder. To do this, from an open terminal or command prompt, navigate to your project folder and type code .:
Note: Users on macOS must first run a command (Shell Command: Install 'code' command in PATH) to add VS Code executable to the PATH environment variable. Read the macOS setup guide for help.
Windows and Linux installations should add the VS Code binaries location to your system path. If this isn't the case, you can manually add the location to the Path environment variable ($PATH on Linux). For example, on Windows, VS Code is installed under AppDataLocalProgramsMicrosoft VS Codebin. To review platform specific setup instructions, see Setup.
Insiders: If you are using the VS Code Insiders preview, you launch your Insiders build with code-insiders.
Core CLI options
Here are optional arguments you can use when starting VS Code at the command line via code:
| Argument | Description |
|---|---|
-h or --help | Print usage |
-v or --version | Print VS Code version (for example, 1.22.2), GitHub commit id, and architecture (for example, x64). |
-n or --new-window | Opens a new session of VS Code instead of restoring the previous session (default). |
-r or --reuse-window | Forces opening a file or folder in the last active window. |
-g or --goto | When used with file:line[:character], opens a file at a specific line and optional character position. This argument is provided since some operating systems permit : in a file name. |
-d or --diff | Open a file difference editor. Requires two file paths as arguments. |
-w or --wait | Wait for the files to be closed before returning. |
--locale | Set the display language (locale) for the VS Code session. (for example, en-US or zh-TW) |
Opening Files and Folders
Sometimes you will want to open or create a file. If the specified file does not exist, VS Code will create them for you along with any new intermediate folders:
Command Tab Plus 1 83 Manual
For both files and folders, you can use absolute or relative paths. Relative paths are relative to the current directory of the command prompt where you run code.
If you specify more than one file at the command line, VS Code will open only a single instance.
If you specify more than one folder at the command line, VS Code will create a Multi-root Workspace including each folder.
| Argument | Description |
|---|---|
file | Name of a file to open. If the file doesn't exist, it will be created and marked as edited. You can specify multiple files by separating each file name with a space. |
file:line[:character] | Used with the -g argument. Name of a file to open at the specified line and optional character position. You can specify multiple files in this manner, but you must use the -g argument (once) before using the file:line[:character] specifier. |
folder | Name of a folder to open. You can specify multiple folders and a new Multi-root Workspace is created. |
Working with extensions
You can install and manage VS Code extensions from the command line.
| Argument | Description |
|---|---|
--install-extension | Install an extension. Provide the full extension name publisher.extension as an argument. Use --force argument to avoid prompts. |
--uninstall-extension | Uninstall an extension. Provide the full extension name publisher.extension as an argument. |
--disable-extensions | Disable all installed extensions. Extensions will still be visible in the Disabled section of the Extensions view but they will never be activated. |
--list-extensions | List the installed extensions. |
--show-versions | Show versions of installed extensions, when using --list-extensions |
--enable-proposed-api | Enables proposed api features for an extension. Provide the full extension name publisher.extension as an argument. |
Advanced CLI options
There are several CLI options that help with reproducing errors and advanced setup.
| Argument | Description |
|---|---|
--extensions-dir | Set the root path for extensions. Has no effect in Portable Mode. |
--user-data-dir | Specifies the directory that user data is kept in, useful when running as root. Has no effect in Portable Mode. |
-s, --status | Print process usage and diagnostics information. |
-p, --performance | Start with the Developer: Startup Performance command enabled. |
--disable-gpu | Disable GPU hardware acceleration. |
--verbose | Print verbose output (implies --wait). |
--prof-startup | Run CPU profiler during startup. |
--upload-logs | Uploads logs from current session to a secure endpoint. |
| Multi-root | |

Opening VS Code with URLs
You can also open projects and files using the platform's URL handling mechanism. Use the following URL formats to:
Open a project
Command Tab Plus 1 830
Open a file
Open a file to line and column
You can use the URL in applications such as browsers or file explorers that can parse and redirect the URL. For example, on Windows, you could pass a vscode:// URL directly to the Windows Explorer or to the command line as start vscode://{full path to file}.
Note: If you are using VS Code Insiders builds, the URL prefix is vscode-insiders://.

Common questions
'code' is not recognized as an internal or external command
Your OS cannot find the VS Code binary code on its path. The VS Code Windows and Linux installations should have installed VS Code on your path. Try uninstalling and reinstalling VS Code. If code is still not found, consult the platform specific setup topics for Windows and Linux.
On macOS, you need to manually run the Shell Command: Install 'code' command in PATH command (available through the Command Palette⇧⌘P (Windows, Linux Ctrl+Shift+P)). Consult the macOS specific setup topic for details.
How do I get access to a command line (terminal) from within VS Code?
VS Code has an Integrated Terminal where you can run command-line tools from within VS Code.
Can I specify the settings location for VS Code in order to have a portable version?
Not directly through the command line, but VS Code has a Portable Mode which lets you keep settings and data in the same location as your installation, for example, on a USB drive.
