Hi,
I am trying to delete 3 characters from the right in a column. I can't find a function that will easily do that. The length of the string keeps changing. Below is some sample data. Please advise.
CA*461*NN
CA*461*NN
CA*461*NN
CA*463*NN
CA*463*NN
CCABM*100*01
CCART*100*01
CCART*100*01
CCICC*114*Z2
CCICC*Z2*Z2
CCLGA*110*01
CCLNG*100*01
CCLNG*100*01
CCLNG*102*01
CCSTD*103*01
CD*001*1S
CD*329*01
CD*329*31
CD*352*01
CD*352*01
CD*352*01
CD*352*01
CD*352*01
CD*352*01
CD*352*01
CD*352*01
CD*352*01
CS*762*51
CS*630*51
CS*772*61
SC*101D*01
SC*101D*02
SC*101*03
SC*101*04
SC*101D*05

Try this if this works..

UPDATE Table SET Column = REPLACE( Column, RIGHT(Column, 3), '' )

Does this help get you in the right direction?

declare @ TestStr varchar(32); -- to get this to post, I added a space between @ and TestStr, remove that space

set @TestStr = 'SC*101D*05';

select @TestStr = left(@TestStr, len(@TestStr) - 3);

select @TestStr;

Lynn,

Thanks. It worked. Here was the solution.

SELECT left (column_name, len(column_name) -3) FROM Table_Name

DECLARE @v-2 VARCHAR(30)

SET @v-2='CA*461*NN'

SELECT LEFT(@v,LEN(@v)-3)

This won't work if the last 3 characters are used in the same sequence elsewhere in the string. I'd really go with the left(len)) option here.

Actually, it doesn't. It works as long as the last three characters aren't repeated anywhere else in the string, but will not work if the characters are repeated. For example, if the original string is "CH*012*01", Kingston's solution will produce "CH2" whereas the correct solution is "CH*012'

Just for the record, it will also delete the wrong data if the right 3 occurs more than once in the string. Don't use it. 😉

I would point out the obvious that there's a reason you're #1 non employee-poster. But that's been said already :hehe:.

Of course I am. Why would you think otherwise ;-).
