Re: [Squirrel-sql-users] SQL 101

[Tyrone B. <tyr...@ho...>]

I will get help from the DBA on that query listed earlier.  The one listed 
below works.  Now, what is it doing:

select * from MGD_REQ_HOLDG m inner join AUTH_REQ_ITEM_HDR a on 
m.REQ_ITEM_HDR_ID = a.REQ_ITEM_HDR_ID
where a.auth_req_id

Do I need to change the MGD_REQ_HOLDG in the first line to look at another 
table?

What is the lower case "m" and "a" for?

Why do you need to add a "a" to a.REQ_ITEM_HDR_ID instead of doing it 
without the "a"?

Sorry... This is SQL for dummies questions.
