Code:
SELECT table2.id
, t1_1.ad_data AS ad_data_1
, t1_2.ad_data AS ad_data_2
, t1_3.ad_data AS ad_data_3
, t1_4.ad_data AS ad_data_4
, t1_5.ad_data AS ad_data_5
, t1_6.ad_data AS ad_data_6
FROM table2
INNER
JOIN table1 AS t1_1
ON t1_1.ad_id = table2.column_ad1
INNER
JOIN table1 AS t1_2
ON t1_2.ad_id = table2.column_ad2
INNER
JOIN table1 AS t1_3
ON t1_3.ad_id = table2.column_ad3
INNER
JOIN table1 AS t1_4
ON t1_4.ad_id = table2.column_ad4
INNER
JOIN table1 AS t1_5
ON t1_5.ad_id = table2.column_ad5
INNER
JOIN table1 AS t1_6
ON t1_6.ad_id = table2.column_ad6
it doesn't have to be this ugly, if table2 were normalized

Actually
i need to extract the data from script column from advertisement table..
notes: column_id_1,....column_id_9 from column_ads table holds advertisement table ad_id data.
i need to extract the script from advertisement table by column_id_1---column_id_9 where page_id = (example:1)
o/p
column_id_1-->2 means i want to extract <script typefghf="text/javascript>\r\nhi</script> bec ad_id is 2
likewise i have to get upto column_id_9

I am sure there is a question in there somewhere but I can't find it. So instead of answering I'll just comment that your column_ads table looks wrong to me - would you do better with :
Code:
CREATE TABLE IF NOT EXISTS column_ads (
id int NOT NULL AUTO_INCREMENT,
page_id int NOT NULL,
column_no tinyint NOT NULL,
add_id int NOT NULL,
PRIMARY KEY (id)
);
Not sure how useful the id column is either - I would just use page_id, column_no and add_id but it depends on your application.
