System Views Missing in SSMS When Using Devart Connector as a Linked Server
When using the Devart ODBC driver as a linked server in SQL Server Management Studio (SSMS), you might encounter a situation where the System Views section appears but contains no visible data.
How to Access Metadata
The necessary metadata can still be obtained by querying the internal views exposed by the Devart driver:
SYS_TABLES – Lists available tables and their parameters
SYS_COLUMNS – Lists table columns, their data types, and positions
SYS_TABLE_CONSTRAINTS – Lists constraints, their types, and associated tables
SYS_REFERENTIAL_CONSTRAINTS – Contains details on foreign keys
Example
To retrieve a list of columns for the Account table, use the following query:
SELECT *
FROM OPENQUERY([LinkedServerName],
'SELECT * FROM SYS_COLUMNS WHERE Table_Name = ''account''')
Replace [LinkedServerName]
with the actual name of your linked server.
