| If you need to connect to Mapr, Hortonworks, or Cloudera distributions of Hive, you must remove the Apache Hive JDBC Drivers that come preinstalled in <ADS_INSTALL>/lib/drivers. Replace them with drivers from your distribution before you choose a new distribution type in the Distribution drop-down within the General Tab. Follow the steps to connect to Hortonworks, Cloudera, or MapR Distributions of Hive on the Apache Hive JDBC Drivers page. |

Edit the Server Properties, to use FILTER options for a Server in Aqua Data Studio:
- Locate the Server in the Server Browser
- Right-click on the Server - A Popup Menu Appears
- Click on the Item which displays Server Properties.
- Go to the Filter Tab and make changes in the Options.
- Filter Databases/Schemas: Allows the user to specify the main schema browser filter for databases or schemas, on whether to include or exclude all.
- Include Databases/Schemas: A list of databases/schemas to include after the main filter is applied.
- Exclude Databases/Schemas: A list of databases/schemas to exclude after the main filter is applied.
- Filter Objects: Allows the user to specify the main schema browser filter for object types, on whether to include or exclude all.
- Include Objects: A list of objects to include after the main filter is applied.
- Exclude Objects: A list of objects to exclude after the main filter is applied.
Features
- You can Create, Edit or Delete Object Folders. Default Folders are Tables, System Tables, Views, Indexes, Triggers, Procedures, Functions.
- Sometimes you would like to view only specific Schemas. Use options to INCLUDE or EXCLUDE all Schemas and Folders.
- Enter the Schema or Folder name in the specified text area and click OK. The current Connection will be terminated. Reconnect to see the changes.
- Filters are case sensitive
- Filter Databases works on the list of databases inside the "Databases" folder.
- Filter Folders works on the list of folders inside a particular database. Example folders: Tables, View, Procedures, etc.
- Object Folder filter works on individual folders inside a particular database. The user can define filters for each of the Tables, Views, etc. folders.
...
If your intention is to show only the tables that start with XXPKD, then you need to change your main filter to "Exclude All", and the secondary filter to "+XXPKD*". Note the "+" in front of the XXPKD pattern. Also, note that the filter pattern is case-sensitive.
The filter shown below is set to exclude all databases except those that start with "aq". This is similar to the above example where all schemas, except the XXPKD schema, are excluded. Then, there is an "Object Folder" filter on the Tables folder, which excludes everything except those that start with "forum".
