Possible Duplicate:
Difference between JOIN and INNER JOIN

I have found some legacy SQL (T-SQL) for MS SQL Server, which has a clause

TableA JOIN TableB

I was just wondering if this is identical to

TableA INNER JOIN TableB

or if there is any difference?

Also, if I were to port this to another database engine, e.g. MySQL, Access, Oracle, would JOIN also always mean the same as INNER JOIN?

Answer 1

Did you try it?

Quoted from palehorse:

They function the same. INNER JOIN can be a bit more clear to read,
especially if your query has other join types (e.g. LEFT or RIGHT)
included in it.
