There are multiple tables, all tables are having same column names with different values, nd I have created one new table with same columns , but I want to put those all data in this new crated single table in SQL. There is no unique id in any of the table. I just want to merge all table data in one sinlge table.

Table names are - Andra Pradesh, Arunachal Pradesh, Assam, Bihar, Chhattisgarh,Delhi,Hariyana,Himachal Pradesh, Karnataka.
      
And all column names are same in all the tables , here is the column names - State, District,Year,January,February,March,April,May,June,July,Aug‌​ust,September,Octobe‌​r,NovemberDecember. And tbl_India this is the new table which I created with the same columns.... I want to add those all data in this new table.

You need to do an insert too:

INSERT INTO blanktable (cola, colb, ...)
SELECT [col_name] FROM tablea
UNION ALL
SELECT [col_name] FROM tableb

Open in new window

you have to insert the query results into the new table:

Select * into new_table  
from  (
SELECT [col_name] FROM tablea
UNION ALL
SELECT [col_name] FROM tableb)

Hi!

Depending on the overall data-size of all the tables you want to merge into the new table.
If the size is over 5 million records then I strongly recommend that you partition the table in such way that you have near-even distribution and the partitioning benefits most or all queries that access the table.
