That is good idea. Thanks. But...
Can I make one view from those two tables? "Union" of them?

>>For example I have 4 same type tables which contains:
>>1 table 1995 year's invoices
>>2 table 1996 year's invoices
>>3 table 1997 year's invoices
>>4 table 1998 year's invoices
>>
>>And for example user wants to know some information from 96-97 years.
