Query library

Query Library lets you store, reuse and share data queries for data sourced across your workspace. Create and run queries in query library, and call them from any Lowcoder app.

Features

The main function of the query **** library is to create and manage reusable queries:

• Writing queries based on data sources, with the ability to define Inputs variables.\

• Importing and triggering queries from query library in apps and modules.\

• Referencing different versions of queries.\

Create a new query

1. Click + New and select a data source.

2. Rename the query on demand.

3. Write code and click ▶ Run to get results. The results will display in the bottom pane of the window.

Input parameters

There are cases where you want to pass dynamic parameters to a query. Lowcoder supports that by introducing input configuration of a query.

Click Add in the Inputs tab in the right pane to add input parameters. Reference them using {{}} in the query, then you can input test values to test execution of the query.

You can only reference variables instead of writing JavaScript code in {{}}.

To edit the name and description of the input variables, click ... and select Edit or directly click the title of the variable.

Version management

Queries may be updated on demand. You can make an adjustment to a query to a newer version and at the same time maintain the older version. Such version management is achievable in query library. Click ··· in the top right corner to publish different versions of queries, and you can view and restore history versions.

Publish

When you finish writing a version of the query, you can publish it. Click ··· > Publish. Use semantic versioning (also known as SemVer) to name your version.

History version

To view and restore the history versions, go to ··· > History version.

You can restore your current draft to a history version by selecting the target version from the history version list and clicking Restore this version. Click Exit to return to edit mode.

Import a query

1. In an app or module, Click + New in the Query editor in the bottom pane, then select Import from Query Library.

2. Select a query from the library from the dropdown list, choose your desired version and pass in corresponding input parameters.
