Hi Guys
Hope everyone is well, i have a field called NAME with some data as shown below
Name
RECA-AA-3-CCC-1
RECA-AB-31-abc-1
RECA-C-3-T
I am trying to write a select statement ( or a script) to remove the Characters 'RECA-' from the names ( shown above) so the output result should be as below
Name
AA-3-CCC-1
AB-31-abc-1
C-3-T
can anyone help me with this?
Thank you

Look at the REPLACE function, and replace with '' (2 quotes, without space between them)

hi
thank you for the reply
Does the replace , replace the data in the original table?
As i dont want that

This will replace the values (overwrite them):
use tempdb;
go
CREATE TABLE Vals(Val VARCHAR(20));
GO
INSERT INTO Vals VALUES
('AAAB-AA-43-DDD-2')
,('RECA-AA-3-CCC-1')
,('RECA-AB-31-abc-1')
,('RECA-C-3-T');
UPDATE Vals
SET Val = REPLACE(Val,'RECA-','')
WHERE Val LIKE 'RECA-%';
If you just want to find them, use something like
SELECT * FROM Vals WHERE Val LIKE 'RECA-%'

If you are running SELECT it is only for display.
UPDATE will change the data in the table.

You can also use Substring() to return a part of the string only.

Thank you
i dont want to replace or ovewrite them.
I just want to pull the data without 'RECA-' at the start

A few choices:
CREATE TABLE Vals(Val VARCHAR(20));
GO
INSERT INTO Vals VALUES
('AAAB-AA-43-DDD-2')
,('RECA-AA-3-CCC-1')
,('RECA-AB-31-abc-1')
,('RECA-C-3-T');
GO
SELECT
REPLACE(Val,'RECA-','') AS Option1
, CASE WHEN SUBSTRING(val, 1, 5) = 'RECA-'
THEN SUBSTRING(val, 6, LEN(val))
ELSE val
END AS Option2
FROM dbo.Vals AS v
you can also use CHARINDEX to find spots in a string to drive substring if there are other patterns you need.

SELECT
STUFF(NAME, 1, CASE WHEN LEFT(NAME, 5) = 'RECA-' THEN 5 ELSE 0 END, '') AS NAME
FROM dbo.table_name
A potential problem with REPLACE is that it will affect the entire string, not just the leading chars. For example, this:
RECA-001-abc-qztb-RECA-LL
would become:
001-abc-qztb-LL
While not at all likely to affect this code, if you only want leading chars changed, it's better to specify that explicitly.

WHERE NAME NOT LIKE 'RECA-%'

WHERE NAME NOT LIKE 'RECA-%'
That will eliminate them from results. The request was to remove the characters 'RECA-' but keep the remaining characters.
