i am having 3 tables in a day , like 90 tables in a month. But the table structure are same for all table , only table name wil change for day by day like 30MAR12_A , 30MAR12_B , 30MAR12_C , 31MAR12_A ... suppose i have to take data for a day then i will be fetching 3 table of that day. Is it possible to integrate my table structure with iReport , how can i use iReport for my reporting purpose. Suppose i am taking 1month data then i have to fetch all these 90 tables. is there any better way - to fetch thismuch data from table. Because database structure is not possible to change , then how ? Could any one help me
