I've got a table with two columns, ID
and Value
. I want to change a part of some strings in the second column.
Example of Table:
ID Value
---------------------------------
1 c:\temp\123\abc\111
2 c:\temp\123\abc\222
3 c:\temp\123\abc\333
4 c:\temp\123\abc\444
Now the 123\
in the Value
string is not needed. I tried UPDATE
and REPLACE
:
UPDATE dbo.xxx
SET Value = REPLACE(Value, '%123%', '')
WHERE ID <= 4
When I execute the script SQL Server does not report an error, but it does not update anything either. Why is that?
You don't need wildcards in the REPLACE
- it just finds the string you enter for the second argument, so the following should work:
UPDATE dbo.xxx
SET Value = REPLACE(Value, '123\', '')
WHERE ID <=4
(I also added the \
in the replace as I assume you don't need that either)
