How to select rows from a table from other table key column value +1


I just went through a situation where there are 2 tables and I need a select rows from first table based on the key column of second table incremented by 1. For example:


1 hari 123

2 hari2 321

3 hari3 432

4 hari4 234

5 hari5 543


1 hari 123

4 hari4 234

The result selection must display 2 and 5 i.e..

2 hari2 321

5 hari5 543

Please share your answers.

Thanks, Ram

1 answer: sort voted first

You can just put that right into the JOIN criteria:

FROM dbo.Table1 AS t1
JOIN dbo.Table2 AS t2
ON t1.ID +1 = t2.ID;
Now, that does act as a function on the column, so it may result in scans. Test it to be sure.

Thanks for your response Fritchey.

My expectation is it should pick 1 nd 4 key values from table 1 and display 2 and 5 from first table.

New code box

There's a new way to format code on the site - the red speech bubble logo will automatically format T-SQL for you. The original code box is still there for XML, etc. More details here.
