Query Workbench

Use the Query Workbench to easily run on-demand SQL queries, translate SQL into its REST equivalent, and view and save results as text, JSON, JDBC, or CSV.

Quick start

To get started with SQL Workbench, choose Dev Tools in OpenSearch Dashboards and use the bulk operation to index some sample data:

PUT accounts/_bulk?refresh
{"index":{"_id":"1"}}
{"account_number":1,"balance":39225,"firstname":"Amber","lastname":"Duke","age":32,"gender":"M","address":"880 Holmes Lane","employer":"Pyrami","email":"amberduke@pyrami.com","city":"Brogan","state":"IL"}
{"index":{"_id":"6"}}
{"account_number":6,"balance":5686,"firstname":"Hattie","lastname":"Bond","age":36,"gender":"M","address":"671 Bristol Street","employer":"Netagy","email":"hattiebond@netagy.com","city":"Dante","state":"TN"}
{"index":{"_id":"13"}}
{"account_number":13,"balance":32838,"firstname":"Nanette","lastname":"Bates","age":28,"gender":"F","address":"789 Madison Street","employer":"Quility","email":"nanettebates@quility.com","city":"Nogal","state":"VA"}
{"index":{"_id":"18"}}
{"account_number":18,"balance":4180,"firstname":"Dale","lastname":"Adams","age":33,"gender":"M","address":"467 Hutchinson Court","email":"daleadams@boink.com","city":"Orick","state":"MD"}

Then return to SQL Workbench.

List indexes

To list all your indexes:

SHOW TABLES LIKE %

TABLE_NAME
accounts

Read data

After you index a document, retrieve it using the following SQL expression:

SELECT *
FROM accounts
WHERE _id = 1

account_number	firstname	gender	city	balance	employer	state	email	address	lastname	age
1	Amber	M	Brogan	39225	Pyrami	IL	amberduke@pyrami.com	880 Holmes Lane	Duke	32

Delete data

To delete a document from an index, use the DELETE clause:

DELETE
FROM accounts
WHERE _id = 0

deleted_rows
