This condition is saying to join a row from table Dressing to a row in table
inserted if the column Dressing_ID are equal in both tables or
inserted.Day_Dressing_ID is null, so if Dressing.Dressing_ID = 1 and
inserted.Dressing_ID is null those rows are joined.

abt RTRIM/LTRIM ,Null values
Hi
can any one solve my problem; i could not get solution for following
query
I have two tables like tblOrg and tblorgchartreport
so i need to update tblorg for newly inserted rows with
tblorgchartreport, suppose there are firstname, lastname
so i need to update these fields in tblorg by triming two fields like
i need to get firstname + lastname from tblorgchartreport into
firstname of tblorg. so i have few null values in lastname fields .
so can any one tell me how to solve avoid null values while using RTRIM
or LTRIM when inserting values
waiting for reply thank you in advance
*** Sent via Developersdex http://www.codecomments.com ***
Hi
You can use this way:
SELECT LTRIM(RTRIM(ISNULL(FirstName,''))) + LTRIM(RTRIM(ISNULL(LastName,'')))

Hi
You can use this way:
SELECT LTRIM(RTRIM(ISNULL(FirstName,''))) + LTRIM(RTRIM(ISNULL(LastName,'')))
