An interesting problem I was facing was adding CLRF on a string in SQL Server. The solution was to add a combination of chars ( CHAR(13) + CHAR(10) ) where the string should break the line. The follwing example will add CLRF in the string being updated.
UPDATE NM196 SET
OSNOVANIE =
'Вал. превод Реф.@@500' + char(13) + char(10) +
