Index is another table which contains the column in ascending/descending order.
Unique Index/ Primary index / Non-nique index etc...

To search the table more efficiantly

If you know the SQL statements at compile time it's static SQL, at Runtime it's Dynamic SQL.

Locking row level, page level, table level & table spce level available.

QMF - Query Management Facility
SPUFI - SQL processor Using File Input
In SPUFI you should create two data sets to provide & view I/O
In QMF data sets not necessary. In QMF you can generate & print reports.
in SPUFI not like that. |
