I have 2 tables

1) tm_Customer(custId,CName,address,contactNo)
2) tm_booking(bID,Amount,CustID)

data in table
1) tm_customer

1, jagdish,asdf,122334
2, ghi,    qwert,34455
3, jkl,    asdfgh,34521
4, iuy,    lkjff,3434

2) tm_booking

1, 12000,  1
2, 123000, 2
3, 2345,   3
4, 1234,   1
5, 123,    4

I am executing query as following:

select bid,cName,address,contactno,amount from tm_booking b,tm_customer c where b.custID=c.custId and bid=2;

so result should be

2 ,ghi, qwert, 34455, 12300

I am getting this result in Datatable but when i am assigning this datatable to crystall report. It shows me like this:

2 ,Jagdish, asdf, 122334, 12300
2 ,ghi, qwert, 34455, 12300
2 ,jkl, asdfgh, 34521, 12300
2 ,iuy, lkjff, 3434, 12300

error is single record of booking table assigned to all record of customer table in crystal report.

can any one suggest me solution???
Thanx in advance.
