# Query A Only

### ![](/files/zHpn0Kr3JoqcJh6Texsw)

### 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.
