I want to use the loop index "i" in the result of my select statement in order to insert it into another table. Is is like:
set i=0;
while i<25 do
insert into a (x,y,z)
select a,b,i
from table1;
set i= i+1;
end while;
What is the way to do it?

The simplest possible looping construct is the LOOP statement. The syntax for this statement is as follows: [ label :] LOOP statements END LOOP [ label ]; The statements between the LOOP and END LOOP statements will be repeated indefinitely, until the LOOP is terminated.
LOOP implements a simple loop construct, enabling repeated execution of the statement list, which consists of one or more statements, each terminated by a semicolon ( ; ) statement delimiter. The statements within the loop are repeated until the loop is terminated. Usually, this is accomplished with a LEAVE statement.
foreach() acts on server side only, and does not require shell access nor the mysql command line client, although it may be spawned from within the mysql client. foreach() accepts several types of collections. They are automatically recognized by their pattern.

I have just created variable i as @i and it is all solved.
Like this:
set @i=0;
while @i<25 do
insert into a (x,y,z)
select a,b,@i
from table1;
set @i= @i+1;
end while;
thx anyway :)
