First.. here are the two tables I\'ve created (sans irrelevant columns)..

Answer 1

If you want to merge to table and you want to select particular column from one table and in another table want to select all.

e.g.

Table name = test1 , test2

query:

SELECT test1.column1,test1.column2, test2.* FROM test1 ,test2

if you want to merge with particular column

query:

SELECT test1.column1,test1.column2, test2.* FROM test1 ,test2 where test2.column3='(what ever condition u want to pass)'
