Cannot find a database object in Database tool window
If you see no objects below the schema level, cannot find changes in objects, experience broken tables or any other visualization problems, try the following steps to resolve the problem.
Step 1. Refresh the database state
If someone changed the remote database data or view, the local view of the database might differ from the actual state of the database.
To synchronize the database state automatically, in the Database tool window ( ), click the Data Source Properties button
and select the data source that you want to change. On the Options tab, select the Auto sync checkbox.If the Auto sync checkbox is cleared, the view of the data source in the Database tool window ( ) is synchronized with the actual state of the database only when you click the Refresh icon
or press Ctrl+F5.
Step 2. Verify that the necessary schemas are selected
When you create a data source, the data source is created with no schemas selected. You need to select schemas with which you plan to work.
To select the schemas, do one of the following:
In the Database tool window ( ) , right-click a data source and navigate to . Select or clear checkboxes of schemas that you want to display or hide. Press Enter.
Click the N of M link near the data source name. In the database and schema selection window, select or clear checkboxes of schemas that you want to display or hide. Press Enter.
The Default schema or Default database is a schema or a database that will be current in connection to a data source. The current schema is a schema that is current in a session. You can change the current schema by using SET CURRENT_SCHEMA. The default schema depends on database settings and data source settings that you set in the JDBC URL.
You can change this default in connection settings of a data source. To change the default, click the Data Source Properties icon in the Database tool window ( ). From the list of data sources, select your data source. In the Database field, type the name of a schema or a database that you want to use as a default.
Step 3. Verify that the tree filter is off
If the items of the object kind are filtered out from the view, the objects wil be hidden in the Database tool window.
To make sure the database object is not filtered out from the view, do the following:
In the Database tool window toolbar, click
View Options.Select
Filter.Navigate to the database object kind and make sure that the checkbox is ticked.
The green dot in the corner of filter icon indicates that the filter is on and some objects are filtered out.
Step 4. Force refresh schema information
The Force Refresh action clears the data source information from cache and loads it again from scratch.
In the Database tool window ( ) , right-click a data source and select .
Step 5. Clear and synchronize the schema cache
Clear the DataSpell schema cache (right-click a data source and select ). Synchronize the view (refer to Step 1. Synchronize the database state).
Collect information by using Diagnostic tools
To profile the introspection and diagnose possible issues, DataSpell can generate three files that include information about the following:
dataSource.txt: the data source.
introspector.txt: a module that was used to load the metadata from the database.
model.xml: a part of the database model.
This information might be helpful when introspection works incorrectly. For example, when you see something outdated or do not see new objects.
Right-click a data source and navigate to .
DataSpell will generate three files with the introspector diagnostic info.
Click the link in the Diagnostic information collected notification message to navigate to the directory with generated files.
The following screenshots show the example output of these three files.
dataSource.txt
introspector.txt
model.xml
Switch to the JDBC-based introspector
Consider this step as a temporary workaround. If you cannot see objects in the Database tool window, you might have a bug. Collect troubleshooting materials and send them to our support team.
Temporarily enable introspection with JDBC metadata
Open data source properties. You can open data source properties by using one of the following options:
In the Database tool window ( ) , click the Data Source Properties icon
.Press Shift+Enter.
On the Data Sources tab, select the data source that you want to modify.
Open the Advanced tab.
From the Expert options list, select the Introspect using JDBC metadata checkbox.
Synchronize the view (see Step 1. Synchronize the database state).
