Trim "-" from sql return data-CodePudding

I have a query that is created in sql server that returns data like:

1234-A
2345-BB
3456-C
5678-CC
4567-AA              
6789-B
01234-A
26857-ZZ

This is what I need it display:

A
B
C
C
A
B
A
Z

I need to get the first letter behind the '-'. How do I get this to display?

Try this:

DECLARE @MyTable TABLE (MyCol VARCHAR(255));
INSERT @MyTable (MyCol)
VALUES ('1234-A'),('2345-BB'),('3456-C'),('5678-CC'),
       ('4567-AA'),('6789-B'),('01234-A'),('26857-ZZ');

SELECT SUBSTRING(MyCol, CHARINDEX('-', MyCol, 1)   1, 1)
FROM @MyTable;

CHARINDEX finds where the '-' in the column value is.
SUBSTRING starts at that index 1 and returns, in this case, 1 character.

You can use substr In conjunction with instr to get the output
