This article will walk you through the steps to ensure your dataset is compatible with any legacy tools that may depend upon legacy querying functionality (local/Slate Template Library queries). These steps are optional, and are not recommended unless needed for a specific purpose. Completing these steps will require using database tools that are shown in gray text and marked as “(legacy tool)”. > [!TIP] > ⭐ Best Practice > > Local and Slate Template Library queries/query bases are no longer in development and are not supported by Technolutions. Unless absolutely necessary, we advise against following the steps in this article and instead recommend using only Configurable Joins queries and database tools. ## Step 1. Preparation This article assumes you have already completed all steps noted in the [Creating a Custom Dataset article](/v1/docs/creating-a-custom-dataset). ## Step 2. Refresh the Slate Template Library 1. From the main navigation, select **Database.** 2. Under Configurations, select **Slate Template Library (legacy tool).** 3. Click the link to manually refresh the Slate Template Library.

Creating a custom query base allows you to use a new dataset in the areas of Slate that do not yet support Configurable Joins, or where Local or Slate Template Library filters are still in use. If your institution is still using the legacy Lookup tool, this step is required to add your new dataset to that tool. To add the query base for the custom dataset: 1. From the main navigation, select **Database.** 2. Under Configurations, select **Slate Template Library (legacy tool).** 3. In the **Search Library**bar, enter the name of the new dataset. 4. Under **Query Bases**, click **Add.** A popup appears.

Set **Status** to Active. [![Insert_Record_in_Query_Bases_-_Set_Status_and_Read_Permission.png](https://cdn.us.document360.io/cd8ea7a6-07f3-4846-a554-627ac016d3e3/Images/Documentation/9926084873755.png)](https://cdn.us.document360.io/cd8ea7a6-07f3-4846-a554-627ac016d3e3/Images/Documentation/9926084873755.png) 1. In the **Order**field, enter a number. This number determines the position of the new dataset in the Lookup tool relative to other record types. 2. Select a **Read Permission** for the dataset query base. Leave all other settings unchanged. 3. Click **Save**. [![New_Query_Base_-_Lookup_Order.png](https://cdn.us.document360.io/cd8ea7a6-07f3-4846-a554-627ac016d3e3/Images/Documentation/9986335947035.png)](https://cdn.us.document360.io/cd8ea7a6-07f3-4846-a554-627ac016d3e3/Images/Documentation/9986335947035.png) ## Step 4: Creating the Lookup Creating a Lookup for a custom dataset displays it in the Record Lookup tool. The Lookup also determines the columns that display for the Dataset Records in the Record Lookup tool. To create the Lookup: 1. From the main navigation, select **Database.** 2. Under Configurations, select **Slate Template Library (legacy tool).** 3. Click the **refresh the Slate Template Library** link at the top of the page. A system dialog appears. 4. Click **OK.** 5. In the **Search Library**bar, enter the name of the new dataset. 6. Under **Query Custom Exports**, select one of the results from the list (it doesn't matter which) and click **Add.** A popup appears. 7. Configure the following settings: - **Base:**Select your new custom dataset. - **Name:**Enter *Lookup* - **Default:** Yes 8. Click **Save.** [![Create_Custom_Dataset_Lookup_Record.png](https://cdn.us.document360.io/cd8ea7a6-07f3-4846-a554-627ac016d3e3/Images/Documentation/9986591595547.png)](https://cdn.us.document360.io/cd8ea7a6-07f3-4846-a554-627ac016d3e3/Images/Documentation/9986591595547.png) With the Lookup record created, we'll create the **partial match**. ## Step 5: Creating the partial match Partial Match creates a “search box” that can be used in the Record Lookup tool to find specific Dataset Records. To create a partial match: 1. From the main navigation, select **Database**. 2. Under Queries, select **Query Exports/Filters.** 3. Click **Insert.**A popup appears. 4. Configure the following settings: - **Base:** Select your new custom dataset - **Name:** Enter *Partial Match* - **Where Clause:** Enter (contains(d. [index], )) - **#1 Operators:** Enter *CONTAINS* 5. Click **Save**. [![Create_Custom_Dataset_Partial_Match_Record.png](https://cdn.us.document360.io/cd8ea7a6-07f3-4846-a554-627ac016d3e3/Images/Documentation/9986718490267.png)](https://cdn.us.document360.io/cd8ea7a6-07f3-4846-a554-627ac016d3e3/Images/Documentation/9986718490267.png) ## Step 6: Assign the New Record form to the Query Base Locate the New Record form for your custom dataset. This will be needed for the following steps. 1. On the **New Record** form, right-click the **New Registration** link on the registration page, and then select **Copy link address**. 2. Select **Database** on the top navigation. 3. Select **Query Bases (legacy tool)**. 4. Select the Query Base of the new dataset. 5. In the **Create Record URL** settings, paste the **New Registration** link that was previously copied. 6. Select **Save**. ![](https://cdn.us.document360.io/cd8ea7a6-07f3-4846-a554-627ac016d3e3/Images/Documentation/image-KM9UZ55P.png) ![](https://cdn.us.document360.io/cd8ea7a6-07f3-4846-a554-627ac016d3e3/Images/Documentation/image-BCAFZ10G.png) When manually adding a record to the custom dataset, if an error appears that reads "Resource not available," this indicates that the query base has not been properly configured. Go to the **Query Base** with the **Database** tool and complete the **Create Record URL** setting.
