Because our modeling layer, LookML, builds on top of the in-database features available, some dialects allow for a more powerful implementation than others.\n\nSupport levels and JDBC installation\n------------------------------------\n\nLooker has two support levels for dialects based on a dialect's built-in feature set and the level of demand by Looker users:\n\n- **Supported**: A dialect that is fully supported by Looker. Looker is committed to improving this dialect implementation and will fix issues based on severity and demand. Looker runs exhaustive tests against this dialect at least weekly to ensure quality.\n\n- **Integration**: A dialect that is partially supported. Looker is able to connect to this dialect, but there are no commitments to improve implementation, fix issues, or regularly run tests against the dialect.\n\nFor the dialects whose value of **JDBC Driver Included?** is **No** , the needed JDBC JAR file is not bundled with the Looker JAR files. For [customer-hosted installations](/looker/docs/customer-hosted-installation-steps) of Looker, you must configure the driver for use with Looker as described on the [Unpackaged JDBC drivers](/looker/docs/unpackaged-jdbc-drivers) documentation page.\n| **Note:** The following table applies to Looker (original). For a list of dialects that Looker (Google Cloud core) supports, see the [Looker (Google Cloud core) documentation](/looker/docs/looker-core-dialects#supported_dialects_for).\n\nLooker (original) supports the following SQL dialects as of Looker 25.14:\n\nDatabase configuration instructions\n-----------------------------------\n\nInstructions are available for these SQL dialects:\n\nLooker does not support new connections for the following dialects. Existing connections will continue to function as expected. For Looker instances with existing connections to these dialects, the following links to documentation are provided for reference:\n\n- [IBM DB2 on AS400](/looker/docs/db-config-ibm-db2-on-as400)\n- [IBM DB2 on LUW](/looker/docs/db-config-ibm-db2-for-luw)\n\nLooker also connects with the following dialects. Reach out to your Looker contact for assistance.\n\n- IBM Netezza\n\nNext steps\n----------\n\nAfter you configure your database to work with Looker, you're ready to [connect Looker to your database](/looker/docs/connecting-to-your-db)."]]
