Taking information from a postgres sql query and putting it into a shell script array
I have a postgres sql statement that is the following:

select age from students;

which gives me the entries:

Code:
Age
---
10
15
13
12
9
14
10

which is about 7 rows of data.

Now what I would like to do with this is use a shell script to create an array age[]. As a results age[1]=10, age[2]=15, age[3]=13, age [4]=12, age[5]=9, age[6]=14, age[7]=10.

Any ideas on how to create a shell script.

I have been able to do the following:

Code:
Unix_Array=$(psql -h $PSQL_HOST $PSQL_RDB $PSQL_USER << EOFF
BEGIN TRANSACTION;
select age from students;
END TRANSACTION;
\q
EOFF
)
echo $Unix_Array

Unix_Array gives me all the ages at once like this:
Code:
10
15
13
12
9
14
10


but I cannot for example parse Unix_Array into individual variables such Unix_Array[1]=10, Unix[2]=15 and so on like I described above. Any ideas?

Thanks,

Jason
