# Query A Only

### ![](https://1143774439-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F1ooXfQ2qWGFRh6lihybt%2Fuploads%2Fgit-blob-82a409549d31b8d9fc2afc92887e9262c1cd3f24%2FIcon_TOB_data.png?alt=media)

### Abstract

Generally the query consists of two sections (Data Source A and B) but it can be helpful to switch off the checkbox `☑ Data Source B` in some cases:

* Automate a whole process with generation of [OMrun Parameter lists](/omrun-help/element-details/test-program-object/rtl-generator.md).
* Query data for your information only

The result is shown in a single query return set and is not compared with another data source.
