Hi,

How can we use multiple values separately in Do...DONE from For Loop which we have fetched from sql script in Shell Script.

For example; We got 2 columns in x ( for x in `sqlplus -s .... ). Now I want to copy both columns to 2 different locations. So How can I do that?


Plz help me....its urgent


Thx a lot,
Immu.

This is not an Unix forum this is an ORACLE forum dedicated to Unix specific issue.
Post your shell question in a Unix forum.

If you have space as delimiter, you can just use "read".

Using KSH:

#Note that there are more tokens in the output than 
#variables, so V2 catches everything till the end of the line.
mybox> echo "one two three" | read V1 V2; echo V1=$V1 V2=$V2       
V1=one V2=two three


mybox> echo "one two three" | read V1 V2 junk; echo V1=$V1 V2=$V2
V1=one V2=two
