.set stored_query_result command
Applies to: ✅ Microsoft Fabric ✅ Azure Data Explorer
Sets a mechanism that stores a query result on the service for up to 24 hours.
If a stored query result name already exists, .set fails. Instead, use .set-or-replace, which deletes the existing stored query result and creates a new one with the same name.
Permissions
You must have Database Viewer permissions to run these commands.

Parameters
| Name | Type | Required | Description |
|---|---|---|---|
async |
string |
If specified, the command will return and continue ingestion in the background. Use the returned OperationId with the .show operations command to retrieve the ingestion completion status and results. |
|
| StoredQueryResultName | string |
✔️ | Stored query result name that adheres to entity names rules. |
| PropertyName, PropertyValue | string |
One or more supported properties. | |
| Query | string |
✔️ | The text of a query whose results will be stored. |
Supported properties
| Property | Type | Description |
|---|---|---|
expiresAfter |
timespan |
Determines when the stored query result expires. Maximum is 24 hours. |
previewCount |
int |
The number of rows to return in a preview. Setting this property to 0 (default) makes the command return all the query result rows. The property is ignored when the command is invoked using async mode. |
Returns
A tabular subset of the records produced by the query, referred to as the "preview", or all records. Regardless of how many records are shown on return, all records are stored.
Character limitation
The command fails if the query generates an entity name with the $ character. The entity names must comply with the naming rules, so the $ character must be removed for the ingest command to succeed.
For example, in the following query, the search operator generates a column $table. To store the query results, use project-rename to rename the column.
.set stored_query_result Texas <| search ['State']:'Texas' | project-rename tableName=$table
Examples
The following example creates a stored query result named Numbers.
.set stored_query_result Numbers <| range X from 1 to 1000000 step 1
Output
| X |
