# SQL and PPL

OpenSearch SQL lets you write queries in SQL rather than the [OpenSearch query domain-specific language (DSL)]({{site.url}}{{site.baseurl}}/opensearch/query-dsl/full-text/).

## Next steps

- Learn about the [SQL and PPL API]({{site.url}}{{site.baseurl}}/search-plugins/sql/sql-ppl-api/).
- Learn about [using SQL within OpenSearch]({{site.url}}{{site.baseurl}}/search-plugins/sql/sql/index/).
- Learn about [using PPL within OpenSearch]({{site.url}}{{site.baseurl}}/search-plugins/sql/ppl/index/).
- Learn about [using Query Workbench for SQL and PPL queries within OpenSearch Dashboards]({{site.url}}{{site.baseurl}}/dashboards/query-workbench/). 
- Learn more about OpenSearch SQL in the [Developer Guide](https://github.com/opensearch-project/sql/blob/main/DEVELOPER_GUIDE.rst).
