searching for a string in an MSSQL db

baranbaran

Nowadays, I am using some other 3rd party solution for the need to find a string in an MSSQL but well, this one might be handy and I can verify it works just fine. Lose the tags and type your db and search str instead of mydbname and I want to find

USE mydbname

      declare @SearchStr nvarchar(100)
      Set @SearchStr = 'I want to find%'
