Find Dependencies in SQL Server: sql_expression_dependencies

Posted on by Ian

In SQL Server, you can use the sys.sql_expression_dependencies system catalog view to return all dependencies on a user-defined entity in the current database. This includes dependences between natively compiled, scalar user-defined functions and other SQL Server modules.

You can use this view to:

  • Return entities that depend on a given entity
  • Return entities on which a given entity depends

So for example, you could use it to return all objects that reference a specific table. You could also use it to return all objects that a specific stored procedure references within its code.

Example of SQL Server’s sys.dm_sql_referenced_entities() Returning an Entity that References a Linked Server

Posted on by Ian

One of the things about the sys.dm_sql_referenced_entities() system dynamic management function is that you can use it on cross-database and cross-server entities.

This means you can find referenced entities that are in a different database and even on a different server.

This article provides an example of sys.dm_sql_referenced_entities() returning a stored procedure that queries a database on a linked server.

How to Fix “Server is not configured for DATA ACCESS” in SQL Server

Posted on by Ian

The “Server is not configured for DATA ACCESS” error in SQL Server is a common error when trying to run a distributed query against a server that has its data access setting disabled.

The error will have the name of the server that you’re trying to access. For example, if your server name is SQL01, the error will read something like this:

Msg 7411, Level 16, State 1, Line 1
Server 'SQL01' is not configured for DATA ACCESS.

“Data access” is a setting that enables and disables a linked server for distributed query access.

A common cause of this error is when you try to run OPENQUERY() against the local server. If you really want to run OPENQUERY() against the server, you’ll need to ensure data access is enabled for that server – even if it’s your local server.

2 Ways to Check if Data Access is Enabled in SQL Server (T-SQL Examples)

Posted on by Ian

In SQL Server, there’s a “data access” setting that enables and disables a linked server for distributed query access. If you ever get the “Server is not configured for DATA ACCESS” error, it’s probably because you’re trying to run a distributed query against a linked server that isn’t configured for data access. This can also happen when you try to run OPENQUERY() against your local server.

You can use sp_serveroption to enable or disable data access on a given server. However, you might want to check the existing settings before you start changing them. The following examples show how to do that.

How to Use the ‘sp_server_info’ Stored Procedure in SQL Server

Posted on by Ian

In SQL Server the sp_server_info system stored procedure returns a list of attribute names and matching values for SQL Server, the database gateway, or the underlying data source. It returns a subset of the information provided by SQLGetInfo in ODBC.

Basically, it allows you to see information about SQL Server.

How to Fix Error Msg 7325 in SQL Server: “Objects exposing columns with CLR types are not allowed in distributed queries”

Posted on by Ian

If you’ve encountered error message 7325 in SQL Server “Objects exposing columns with CLR types are not allowed in distributed queries” it’s probably because you’re trying to run a distributed query against a table that contains one or more columns with CLR types.

For example, you could be querying a table that uses a geography or geometry data type in one or more of its columns. These data types are implemented as .NET common language runtime (CLR) data types in SQL Server. And as the error message says, “Objects exposing columns with CLR types are not allowed in distributed queries”.

Fortunately, there’s an easy fix for this issue. And the answer is provided with the full error message.
