General Tab

Tab Coloring

To Identify Server Environments, whether it is a Production, Development or Test, use Tab Coloring feature:

• Locate the Server in the Server Browser.
• Right-click on the Server - A Popup Menu Appears.
• Click on the Item which displays Server Properties.
• Based on the Server Type, you can edit the Tab Coloring option to identify your environments.

Using the Keyboard combination "CTRL + SHIFT + P", you may quickly access Server Properties and edit Tab Coloring options.

Using Filters Options in Registration (Filter Tab)

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 Projects: Allows the user to specify the main schema browser filter for projects, on whether to include or exclude all.
• Include Filter Projects: A list of Projects/datasets to include after the main filter is applied.
• Exclude Filter Projects: A list of Projects/datasets 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, Views.
• 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 Press OK. Current Connection will be terminated. Reconnect to see the changes.
• Filters are case sensitive.
• Filter Projects works on the list of projects inside the "Projects" folder.
• Filter Folders works on the list of folders inside a particular dataset. Example folders: Tables, Views.
• Object Folder filter works on individual folders inside a particular dataset. The user can define filters for each of the Tables, Views folders.

Using the drop-down at the top of the Filter Tab, quickly change your Schema or Folder View.

Filter Examples:

If your intention is to show only the tables that start with XXPKD, then you'll need to change your main filter to "Exclude All", and 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 projects 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".

Using Advanced Properties (Advanced Tab)

Edit the Server Properties to use Advanced Properties 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 Advanced Tab and make changes in the Options.

  With options in Advanced properties of a Server, you can:

• Manage Driver Parameters.
• Enable Project Filters in Query Analyzer.
• Change Read Only / Read- Write Mode.
• Change Object Folder Display.

• Transaction Isolation Level: Support for setting Transaction Isolation Level - TRANSACTION_NONE - A constant indicating that transactions are not supported.
  - TRANSACTION_READ_COMMITTED - A constant indicating that dirty reads are prevented; non-repeatable reads and phantom reads can occur.
  - TRANSACTION_READ_UNCOMMITTED - A constant indicating that dirty reads, non-repeatable reads, and phantom reads can occur.
  - TRANSACTION_REPEATABLE_READ - A constant indicating that dirty reads and non-repeatable reads are prevented; phantom reads can occur.
  - TRANSACTION_SERIALIZABLE - A constant indicating that dirty reads, non-repeatable reads, and phantom reads are prevented.
• JDBC Escape Processing: Allows JDBC driver to perform escape sequence before sending the SQL code to the server.
• Display System Folders: Allows to show/hide System Tables in Tables.
• Always Display Column Name in Results: Allows to show/hide column names in query results.
• Enable DB Filters for Query Window: Enables/Disables db filters for query windows using this connection.
• Only Display Databases that User has Access to: Displays only the databases the current user (from the Login Name on the General tab) has access to within the schema browser.
• Fetch Size: Determines the Fetch Size (number of rows physically retrieved from the database at one time by the JDBC driver).
• Connections Pooled: Enables connection pooling. Read more about connection pooling here.
• Force Auto-Commit: When this option is selected, it sets auto-commit to TRUE for any Query Window to this server and disables the icons on the toolbar.
• List of Additional Project IDs: Specify the project ID of shared datasets.
• Destination Table - Project ID: Specify the project ID for destination table.
• Destination Table - Dataset ID: Specify the dataset ID for destination table.
• Destination Table - Table ID: Specify the table ID which should work as a destination table.
• Destination Table - Write Preference: Specify the write preference on the resultant table.
  - Write if empty - Writes the data if the table already exists and contains data otherwise returns an error.
  - Append to table - Appends the data to the table if the table already exists. 
  - Overwrite table - Overwrites the data to the table if the table already exists. 
• Destination Table - Results Size - Allow Large Results: Allows you to create large result tables randomly for the selected destination table. 
• Destination Table - Results Size - Flatten Results: Allows you to flatten all nested and repeated fields in the single query results.
• Query Caching - Use Cached Results: Allows you to use results from a previously executed query as long as the referenced tables are not modified. You can cache results for approximately 24 hours. The results of the executed query will not be cached if the destination table is selected.  
• SQL Version - Use Legacy SQL: Allows you to run the query using Legacy SQL.
• Data Warehouse Mode: Read Only or Read/Write.
• Data Warehouse "Read Only" Warning Message: Allows you to set a customized warning message when "Read Only" mode is selected.
• Object Folder Display: [Default], [Name], [Schema].[Name] or [Name]([Schema]) sets how the Schemas will be displayed.
• Dataset Folder Grouping: Default, Yes or No. Dataset Folder Grouping makes finding tables much easier because it groups them instead of showing each object individually.

Using the drop-down at the bottom of the Advanced Tab, quickly change your Object Display in the Server Browser. Also, if the 'Destination Table - Result Size - Allow Large Results' is checked, then it is must to specify the first three options in Query Options section.

Server Permissions (Permissions Tab)

• This allows the user to cd (change directory) for a server connection. (Example: cd /scripts)

Server Connections (Connection Monitor Tab)

• Set a ping operation that allows activity on the connection to prevent the connection from being terminated.
• Set an execute operation that executes the Query Window on a periodic basis.
• Set an auto-commit operation that checks how long the auto-commit has been disabled and whether the idle threshold has been exceeded. A warning threshold can also be configured so users can turn on auto-commit before it happens.
