PRB: Proper Handling of the Escape Sequence \<cr><lf> (164291)

SYMPTOMS

Microsoft SQL Server identifies a Transact-SQL command containing the backslash (\) followed by the carriage return (0x0d) and line feed (0x0a) as an escape sequence.

The following example demonstrates the behavior:

   use pubs
   go
   drop table tblTest
   go
   create table tblTest
   (
      strData varchar(30)
   )
   go
   insert into tblTest values ("c:\ 
   X")
   go
   insert into tblTest values ("c:\\ 
   X")
   go
   select * from tblTest
   go
				

   strData
   ------------------------------
   c:X
   c:\ 
   X
				

The first insert contains the \<cr><lf> sequence, and when returned from SQL Server, is c:X. The escape sequence is scanned out by the SQL Server.

However, replacing the \<cr><lf> with \\<cr><lf><cr><lf>, as in the second insert, yields the expected results.
