# T-SQL

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

Discover and update the T-SQL-specific [Analysis parameters](/sonarqube-server/analyzing-source-code/analysis-parameters.md) by going to **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.

## In-line suppression of issues <a href="#in-line-suppression-of-issues" id="in-line-suppression-of-issues"></a>

Adding the -- NOSONAR comment at the end of the line will suppress all issues on that line.

{% hint style="warning" %}
Rather than relying on this method, we suggest refining your analysis scope to avoid creating major gaps in your code review. Because the `NOSONAR` comment silences all current and future issues on a line without regard for their severity, it is an imprecise tool. Even if you only intend to hide a minor stylistic point, you could unintentionally obscure a serious security flaw.
{% endhint %}

{% hint style="info" %}
The rules `NoSonar` allows tracking in-line suppression comments in T-SQL code.
{% endhint %}
