ALTER TABLE ALTER COLUMN DROP ROWGUIDCOL failed because a column does not exist in table ‘%.*ls’ with ROWGUIDCOL property.

Error Message:
Msg 4926, Level 16, State 0, Line 1
ALTER TABLE ALTER COLUMN DROP ROWGUIDCOL failed because a column does not exist in table ‘%.*ls’ with ROWGUIDCOL property.

Severity level:
16.

Description:
This error message appears when you try to alter a column and drop the ROWGUIDCOL property from that column of a table but the table does not have a column with that property.

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. You cannot drop the ROWGUIDCOL property from a table that does not have a column with the ROWGUIDCOL property.

Versions:
All versions of SQL Server.

Example(s):
USE tempdb;
GO
IF OBJECT_ID(‘tempdb..#t’) > 0
 DROP TABLE #t
GO
CREATE TABLE #t
(
 c1 INT
)
GO
ALTER TABLE #t
 ALTER COLUMN c1 DROP ROWGUIDCOL

Remarks:
In the above example we try to drop the ROWGUIDCOL property from the column c1 of the table #t via ALTER TABLE ALTER COLUMN DROP ROWGUIDCOL command. Because c1 does not have this property defined, the error is raised.
