Use the T-SQL Replace keyword to change subsets of string values.  Will probably want to do this a couple of times to handle all the upper case / lower case scenarios.

UPDATE dbo.Company
SET 
   ACCTdirect = REPLACE (ACCTdirect, 'C:\DataMasons' , 'D:\'), 
   EDIdirect = REPLACE (EDIdirect , 'C:\DataMasons' , 'D:\'), 
   vpEDIdirect = REPLACE (vpEDIdirect, 'C:\DataMasons' , 'D:\'), 
   vpSharedirect = REPLACE (ACCTdirect, 'C:\DataMasons' , 'D:\')

Open in new window

You don't need to execute the command several times:
UPDATE dbo.Company
SET 
   ACCTdirect = REPLACE (ACCTdirect, 'C:\DataMasons' COLLATE Latin1_General_CI_AS , 'D:'), 
   EDIdirect = REPLACE (EDIdirect , 'C:\DataMasons' COLLATE Latin1_General_CI_AS , 'D:'), 
   vpEDIdirect = REPLACE (vpEDIdirect, 'C:\DataMasons' COLLATE Latin1_General_CI_AS , 'D:'), 
   vpSharedirect = REPLACE (ACCTdirect, 'C:\DataMasons' COLLATE Latin1_General_CI_AS , 'D:')

Open in new window

Of course, if your columns are case insensitive already then the COLLATE is not necessary.

Try below

UPDATE dbo.Company
SET
   ACCTdirect = REPLACE (ACCTdirect, 'C:\DataMasons' COLLATE Latin1_General_CI_AS , 'D:'),
   EDIdirect = REPLACE (EDIdirect , 'C:\DataMasons' COLLATE Latin1_General_CI_AS , 'D:'),
   vpEDIdirect = REPLACE (vpEDIdirect, 'C:\DataMasons' COLLATE Latin1_General_CI_AS , 'D:'),
   vpSharedirect = REPLACE (ACCTdirect, 'C:\DataMasons' COLLATE Latin1_General_CI_AS , 'D:')

Thanks for the accept.  Good luck with your project.  -Jim

@pcelba and pawan - I'm glad you guys posted, as I didn't know you can combine REPLACE with COLLATE.  I can predict sitting for a SQL 2016 T-SQL exam and getting that as a question, and not answering it correctly if it were not for reading your posts.

BTW, I wouldn't say Jim's solution works best it was just faster but it also produces double backslashes on output...  :-)
