Difference between the querries.

[getmeidea]

I have two tables
1. AccountMaster(AccountID int, Name varchar(20))
2. Transactions(TransID, AccountID int, Amount float)

I have two queries for achieving the same result set. They are

Query1:
Select A.AccountID,A.Name,T.TransID,T.Amount
from AccountMaster A, Transactions T
where T. AccountID=A. AccountID

Query1:
Select A.AccountID,A.Name,T.TransID,T.Amount
from AccountMaster A
inner join Transactions T
on T. AccountID=A. AccountID

Here both will make use of inner join then,
Is there any difference in executing the queries ?
If yes, why SQL Server provides both the option ?

I am not sure but one uses a cross join, the best thing for you is to look up joins, also it is mainly to do with speed issues. In some cases it may actually be nessecary to use a inner join that a cross join can't do or doesn't allow.

this kind of qry may easy for join one or two tables with 1 or 2 fields, but if u go beyond that
you have to write many condition with combination in where clause
for join itself. some more conditions for selecting records after joining...
