Posted
Updated 22-Aug-22 1:26am

Conversion failed when converting from a character string to uniqueidentifier.
This error message appears when you try to convert an invalid character string to uniqueidentifier.

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

Resolution:
Error of the Severity level 16 are generated by the user and are corrigible by the user. The statement cannot be run this way. Only valid character strings can be converted to uniqueidentifier.

Provide your code where you got this error to resolve it.

Select MediaAlbumId from dbo.MediaAlbums where Guid='0f86759f-db8d-47dd-b862-8500afc1bf7e666'

When i enter anything wrong in Guid like i put vvvv in Guid than it gives error
"Conversion failed when converting from a character string to uniqueidentifier."

Thank you Manas!
'0f86759f-db8d-47dd-b862-8500afc1bf7e666' is not a valid Guid, that's easy to see: bytes are encoded as hexadecimal numbers, hence every byte takes up two characters. And now count the characters in each block: the last block has an odd number.

0f86759f-db8d-47dd-b862-8500afc1bf7e666 is an unconditional statement. Try different and valid GUID.

You have essentially just said exactly the same thing that Bernhard Hiller said 10 years ago. Please take care that you are adding something new to a thread if you are going to revive it
