Dear All, I have converted a DB from SQL to Oracle through Oracle SQL Developer Migration tool. After this I have checked the table values, there is no records found has been declared. But table structure has been created. can anyone guide me to solve this issue. Previously in this same mannar I have converted three SQL DB's to Oracle it all works fine, Only this DB having this problem. The only difference is DB size has been greater, when compared to the previous three DB's sizes. Can anyone please guide me to solve this issue. Thanks in advance.
