Re: LEFT OUTER JOIN

Hi Yigit,

please see if you are using left outer join between two tables say table TAB1 having 10 sets of data and TAB2 with  15 sets of data,

if you will use LEFT INNER JOIN in tab1 and tab2, then it will see only the entries in tab1,

so you will have a set of 10 records, but you will loose the additional 5 records which are present in tab2

so for such type of conditions we uses LEFT OUTER JOIN, in which it tooks in consideration for both the tables on which you have taken a outer join, in this way you will get all the from both the tables,

without loosing any data.
