Ошибка 208 sql server

In this article we explain about ERROR 208, why it occurs and how to deal with it.

We often come across situations which seem to be very complicated and challenging but are actually very easy to get out of; provided we think logically. One such situation a lot of SQL Server DBA’s come across is the SSMS error 208, i.e. the ‘Invalid Object Name’ error. This is a very commonly occurring error which ends up confusing a lot of DBAs. So today, we will not only provide you with a solution to this problem, but also suggest you ways to avoid it from occurring in future.

What is Error 208 in SSMS

A lot of us or those DBAs who are not very experienced with using SQL Server, usually opt for exploring the software with the help of SQL Server Management Studio (SSMS). And while you are at it, you might click at a given object to know more about it, and suddenly come across a pop up stating ERROR 208! This is a point where a lot of you might get stuck. But after reading this article we hope things would get better as you would get a greater understanding of the subject.

What is most perplexing about this error to majority of DBAs is the fact that the object is visible to them in SSMS Object Explorer window but when they attempt to select it using T- SQL, they witness the error. This is the point where a lot of DBAs switch to extreme and desperate measures like restarting SSMS multiple times to furiously refreshing queries, restarting databases, etc. But to their sorrow, none of this will provide them with the solution they are looking for.

These practices fail to work because none of these is addressing the root cause of the error which is nothing but simple mismatch in database context.

How to Solve Error 208 in SSMS

Now that you know what is causing the error, finding the solution should not take long. The most common reason for this context mismatching error to occur is the fact that the default database context has been set to master. Well in 99 out of 100 cases, this ends up being the cause. And if this really is what is causing the error to appear in your system, then a very basic thing for you to do is changing the context of the database. And while you are at it, change it in a way that the context becomes similar to the current database object that is in use.

Once you perform this step, you will be glad to see that the error will appear no longer, and all other functions will also happen smoothly. This is one of those errors that almost every single DBA would have experienced, but few would actually know a way out of this situation without considering a repair sql action. This article would hopefully be of help to all of them. Apart from the solution given above, there is one more option that DBAs can try out; this involves prefixing multipart database name to the database that is in use. Or you might also want to change the database that opens by default once you login SSMS.

If you encounter error Msg 208, Level 16 “Invalid object name ‘OPENJSON’.”, you are probably trying to use the OPENJSON() function on a database with a compatibility level of less than 130.

OPENJSON() is only available under compatibility level 130 or higher.

To fix this, either increase the compatibility level of your database to 130 or higher, or change to a database that already has the appropriate compatibility level.

Example of Error

Here’s an example of some basic code that will cause this error.

USE Pets;
SELECT * FROM OPENJSON('["Cat","Dog","Bird"]');

Result:

Msg 208, Level 16, State 1, Line 1
Invalid object name 'OPENJSON'.

When your database compatibility level is lower than 130, SQL Server can’t find and run the OPENJSON() function.

In my case, the database I was trying to run this on had a compatibility level of 120.

Check the Compatibility Level of the Database

You can query sys.databases to check the compatibility level of the database (or all databases if you prefer).

SELECT compatibility_level
FROM sys.databases
WHERE name = 'Pets';

Result:

+-----------------------+
| compatibility_level   |
|-----------------------|
| 120                   |
+-----------------------+

As suspected, this database has a compatibility level of less than 130.

Solution 1

The most obvious solution is to increase the compatibility level of the database for which you’re trying to run OPENJSON() against.

ALTER DATABASE Pets  
SET COMPATIBILITY_LEVEL = 150;

Running that code will increase the database’s compatibility level to 150, which is more than high enough to support the OPENJSON() function.

If we check the compatibility level again, we can see that it’s increased to 150.

SELECT compatibility_level
FROM sys.databases
WHERE name = 'Pets';

Result:

+-----------------------+
| compatibility_level   |
|-----------------------|
| 150                   |
+-----------------------+

Now we can run the original code without error.

USE Pets;
SELECT * FROM OPENJSON('["Cat","Dog","Bird"]');

Result:

+-------+---------+--------+
| key   | value   | type   |
|-------+---------+--------|
| 0     | Cat     | 1      |
| 1     | Dog     | 1      |
| 2     | Bird    | 1      |
+-------+---------+--------+

Solution 2

If for some reason you can’t, or don’t want to, change the compatibility level of the database, you could switch to a database that already has the appropriate compatibility level.

Obviously, this may or may not be suitable, depending on whether you need to insert your parsed JSON into the database or not.

Anyway, to do this, you could query sys.databases for a suitable database.

SELECT 
    name,
    compatibility_level
FROM sys.databases;

Result:

+--------------------+-----------------------+
| name               | compatibility_level   |
|--------------------+-----------------------|
| master             | 150                   |
| tempdb             | 150                   |
| model              | 150                   |
| msdb               | 150                   |
| Music              | 150                   |
| Test               | 150                   |
| WideWorldImporters | 130                   |
| World              | 140                   |
| Pets               | 120                   |
+--------------------+-----------------------+

Fortunately in this case, all other databases are 130 or higher. So we could switch to any one of them.

USE World;
SELECT * FROM OPENJSON('["Cat","Dog","Bird"]');

Result:

+-------+---------+--------+
| key   | value   | type   |
|-------+---------+--------|
| 0     | Cat     | 1      |
| 1     | Dog     | 1      |
| 2     | Bird    | 1      |
+-------+---------+--------+

Error 208

Severity Level 16

Message Text

Invalid object name '%.*ls'.

Explanation

This error occurs when an object that does not exist is referenced. If the object exists, you might need to include the owner’s name in the object name.

If the object is not owned by the user attempting to access it, and it is not owned by the database owner, all references to the object must include the owner’s name. For example, if user1 creates a table called test, other users must use the name user1.test when they refer to the table.

The Microsoft® SQL Server™ naming convention for database objects is:

[[[server_name.][database_name].][owner_name].]object_name

The default value for server_name is the current server and the default value for database_name is the current database. The default value for owner_name is the current user. Because owner_name is part of the object name, it is possible for two different users to have tables with the same name in the same database (for example, user1.test and user2.test). For more information about naming conventions, see Transact-SQL Syntax Conventions.

This message can also occur when you reference a temporary table that was created with an EXECUTE statement.

Action

The procedure for handling this error depends on what you know about the object indicated in the error message text.

The appropriate permissions must also be set to allow access to an object. If these permissions are not set, error 229 or 230 occurs.

If you do not know who owns the object

• Execute sp_help with no parameters to display the object owner.

  Or

• Query the Information Schema Views if the object is a table or view to determine the object owner and type. If the object is not a table or a view, query the sysobjects system table to determine the object owner and type.

For example, to determine the owner and type for the object named table_1, execute the following:

USE master
GO
SELECT TABLE_SCHEMA
FROM INFORMATION_SCHEMA.TABLES
WHERE TABLE_NAME = 'table_1'
GO

If no rows are returned from this query, the object either resides in a different database or does not exist.

If you do not own the object in question

• Include the object owner in the object name. For example:

  SELECT * 
  FROM user1.table_1
  

  Although using fully qualified object names eliminates this problem, remember that including the fully qualified object name in an application might complicate the maintenance of the application. For example, if all references to a table include the database name, changing the database name could become difficult.

  Or

• Have the database owner create the object. If the owner creates the object, any user can find the object without specifying the owner. However, temporary tables reside in tempdb and are dropped automatically when the user process or server connection that created them is terminated. Users cannot share temporary tables, even if they are created by the database owner.

If the object does not reside in the database

• Switch context to the correct database using the USE statement. For example:

  USE database_1
  

  Or

• Qualify the object name with the database name. For example:

  SELECT * 
  FROM database_1.user1.table_1
  

  If you own the object or if the object is owned by the database owner, the owner name is not needed. For example:

  SELECT * 
  FROM database_1..table_1
  

If a temporary table created with an EXECUTE statement is referenced

• If you must use the EXECUTE statement to create a temporary table, create it as a global temporary table using the syntax ##tablename.
