Optimal SQL Query

Hallo Experts,

i am getting the same result with the following two sql s

1.
---

select a.PONo, a.AMCBy, b.CurrentStickerNo
from AMCEntry a, StickerDetails b where a.StickerNo=b.ActStickerNo
order by a.PONo desc

AND

2.
---
select AMCEntry.PONo, AMCEntry.AMCBy, StickerDetails.CurrentStickerNo
from AMCEntry
inner join StickerDetails
on AMCEntry.StickerNo=StickerDetails.ActStickerNo
order by AMCEntry.PONo desc


my question is, which one is suggested to use and why?

Thanking you,
Soumen

Hello!

these two queries are exactly the same. The last one formally closer to the standard. But really you can use any of them

as OMC2000 says they are functionally the same and looking at the execution plan for each query would show no difference, however I think the second statement is more adherent to what would be expected by most people trying to standardise there SQL code and make it more readable

Although they are the same, you must follow the rules, must specify the exact type of join (so go with the second one)
