Try:
SELECT column1 FROM [Table A]
"This is ok fine friend but i am sorry friend how to call the Table A column1 value from Table B column2,column3 display Gridview? please help me friend!!!"
Not exactly sure what you want, but...
SELECT b.column3, a.column2 FROM [Table B] b
JOIN [Table A] a
ON b.column2=a.column1
Might be what you want - if not, then try giving an example instead of random example names! :laugh:
