Hi,
Here i am giving the procedure , how to make the table into
half..... using program... I dont know whether any direct
SQL command is there or not. This is just for ur idea what
i know.
1) Find the total number of rows in a table using count(*)
2) Declare two variable in working storage section.
eg: 02 A pic 9(4) .
02 B pic 9(2).
store the count no into one variable .assume u stored that
in A.
then divide that by 2. so u will get half of the rows in a
table. strore that value in B.
3) Take another variable name C .
eg: 02 c pic 9(4) value 0.
perform para1 until B =C
para1:
Retrive the row from the table.
move to corresponding host variables ( use table to store
muliple rows ).
insert into table(u can insert multiple rows at a time ...)
do the same for storing the other half into the another
table.
means here 1 st half rows were stored in one temp
table .... the other in the one table.
