ALTER TABLE SWITCH statement failed. Target table '%.*ls' has an XML index '%.*ls' on it. Only source table can have XML indexes in the ALTER TABLE SWITCH statement.

Error Message:
Msg 4983, Level 16, State 1, Line 4
ALTER TABLE SWITCH statement failed. Target table ‘%.*ls’ has an XML index ‘%.*ls’ on it. Only source table can have XML indexes in the ALTER TABLE SWITCH statement.

Severity level:
16.

Description:
This error message appears when you try to execute an ALTER TABLE SWITCH command, for which the target table has an XML index.

Consequences:
The T-SQL statement can be parsed, but causes the error at runtime.

Resolution:
Errors of the Severity Level 16 are generated by the user and can be fixed by the SQL Server user. The statement cannot be executed this way. The target table cannot have an XML index.

Versions:
This error message was introduced with SQL Server 2005.

Example(s):
USE Pubs
GO
CREATE PARTITION FUNCTION myPartFunction (int)
    AS RANGE LEFT FOR VALUES (1, 10, 100);
GO

CREATE PARTITION SCHEME myPartScheme
    AS PARTITION myPartFunction
   ALL TO ([PRIMARY]);
GO

CREATE TABLE myPartTable
(
 c1 int PRIMARY KEY,
 myXML xml
)
ON myPartScheme (c1);

GO
CREATE TABLE myNonPartTable
(
 c1 int PRIMARY KEY,
 myXML xml
)
ON [PRIMARY];
GO
CREATE PRIMARY XML INDEX ix_XML_myNonPartTable_myXML
    ON myNonPartTable(myXML);

ALTER TABLE myPartTable SWITCH PARTITION 1 TO dbo.myNonPartTable ;
GO

DROP TABLE myNonPartTable, myPartTable;
DROP PARTITION SCHEME myPartScheme;
DROP PARTITION FUNCTION myPartFunction;

Remarks:
In the above example we try to execute an ALTER TABLE SWITCH command. Because the target table has an XML index defined on it, the error is raised.
