ALTER TABLE SWITCH statement failed. Target table ‘%.*ls’ and source table ‘%.*ls’ have different vardecimal storage format values.

Error Message:
Msg 4984, Level 16, State 1, Line 2
ALTER TABLE SWITCH statement failed. Target table ‘%.*ls’ and source table ‘%.*ls’ have different vardecimal storage format values. Use stored procedure sp_tableoption to alter the ‘vardecimal storage format’ option for the tables to make sure that the values are the same.

Severity level:
16.

Description:
This error message appears when you try to execute an ALTER TABLE SWITCH command for which source and target table have different settings for the vardecimal storage format.

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. Source and target table must have identical settings for the vardecimal storage format.

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

Example(s):
USE master;
GO

IF DB_ID (‘test’) IS NOT NULL
    DROP DATABASE test;
GO

CREATE DATABASE test;
GO

EXEC sp_db_vardecimal_storage_format ‘test’, ‘ON’ ;
GO

USE test;
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,
    c2 varchar(10)
) ON myPartScheme (c1);
GO

EXEC sp_tableoption ‘myPartTable’, ‘vardecimal storage format’, 1;

CREATE TABLE myNonPartTable
(
    c1 int,
    c2 varchar(10)
) ON [PRIMARY];
GO

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

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

Remarks:
In the above example we try to execute an ALTER TABLE SWITCH command. Because source and target table have different settings for the vardecimal storage format, the error is raised.
