I have a field called Batch_No. with values like HOU-014583 and CAR-012334
I need to be able to select the last value with the first 3 of HOU and get the last number, then add one. So I need to make a value like HOU-014584

You can do it like this (assuming your column name is x). However, something about this makes me uneasy, and leads me to believe that there may be opportunities to improve the design, if you have the ability to do so.SELECT
'HOU-'+RIGHT(CAST(MAX(CAST(RIGHT(x,6) AS INT)) + 1 AS VARCHAR(32)),6)
FROM
YourTable
WHERE
x LIKE 'HOU-%' |

SELECT LEFT(batch_no,LEN(batch_no) - 1) +CAST(right(batch_no,1) +1 AS varchar)
FROM tablename |

CREATE TABLE #abc
(batch_no VARCHAR(20))
INSERT INTO #abc
(batch_no)
VALUES ('HOU-014579' -- batch_no - varchar(20)
)
SELECT LEFT(batch_no,LEN(batch_no) - 1) +CAST(right(batch_no,1) +1 AS varchar)
FROM #abc
This is what I got
(No column name)
HOU-0145710
Should not be this as a result.Please advise |

I think the OP is trying keep the length of the string the same and get the next number - so it would be HOU-014580 |

In that case,,
SELECT LEFT(batch_no,LEN(batch_no) - 1) + CAST(CASE WHEN LEN (RIGHT(batch_no,1) + 1 )>1 THEN (RIGHT(batch_no,2) + 1 ) ELSE (RIGHT(batch_no,1) + 1 ) END AS VARCHAR)
FROM #abc |

FROM #abc
Wouldn't that be deferring the same issue to the 100th place? Fo r example, if the input value was HOU-014699. I think it might be easier if we convert it to a number and added 1. Of course, if we do that, what happens if the input is HOU-999999 is left unanswered. |

And that brings us back to your point of changing the design.

Haha, I knew I was on to something, although I couldn't put my finger on it. |
