## Language-specific properties <a href="#language-specific-properties" id="language-specific-properties"></a>

Discover and update the T-SQL-specific [analysis-parameters](https://docs.sonarsource.com/sonarqube-server/2025.1/analyzing-source-code/analysis-parameters "mention") in **Administration** > **Configuration** > **General Settings** > **Languages** > **T-SQL**

## Important note <a href="#important-note" id="important-note"></a>

With the default configuration, only files with the `.tsql` are analyzed as T-SQL, and files with the `.sql` file extension are analyzed as PL/SQL. This behavior is defined in **Administration** > **Configuration** > **General Settings** > **Languages** > **T-SQL** > **File Suffixes** and **Administration** > **Configuration** > **General Settings** > **Languages** > **PL/SQL** > **File Suffixes**. You can override these properties either at the server level or at the project level.
