Answer / mehdee
That is correct, Alias is an alternate name of the table
and it is used so that application programs will always be
right accessing these DB2 tables, for example:
table name alias name
- - - - - - - -
TABLE_A DATA_FOR_MON_0 (current mon)
TABLE_B DATA_FOR_MON_1 previous
TABLE_C DATA_FOR_MON_2
> now at the end of the month we want to purge the 3rd
month data and start fresh to add or load data for the
duration of the new cuurent month, so what DBADM does is
they simply EMPETY the last month DB2 table and reALIAS the
other two as:
table name alias name
- - - - - - - -
TABLE_C DATA_FOR_MON_0 (current mon)
TABLE_A DATA_FOR_MON_1 previous
TABLE_B DATA_FOR_MON_2
So the application programs using alias name will always
be right about which table is for which month.
