Assigning multiple column's value from Oracle query to multiple variables in UNIX
Hi All,
I need to read values of 10 columns from oracle query and assign the same to 10 unix variables. The query will return only one record(row).
I tried to append all these columns using a delimiter(;) in the select query and assign the same to a single variable(V) in unix. I thought I could use 'cut' and assign values to all the required 10 variables from V.
But the thing is some of the the columns have special character and it is kind of hard for me to cut out the required details. Sometimes the delimiter(;)itself is present in column value. Also the code is very lengthy.
Is there a better way to assign multiple column values from query to unix variables.?
Also when i read '-e' from query and pass it unix varaible it becomes '?e'. Is there anyway we could solve this.
Thanks.

CUT(1) General Commands Manual CUT(1)
NAME
cut - select out columns of a file
SYNOPSIS
cut [ -b | -c] list [file...]
cut -f list [-d delim] [ -s]
OPTIONS
-b Cut specified bytes
-c Select out specific characters
-d Change the column delimiter to delim
-f Select out specific fields that are separated by the
-i Runs of delimiters count as one
-s Suppres lines with no delimiter characters, when used
EXAMPLES
cut -f 2 file # Extract field 2
cut -c 1-2,5 file # Extract character columns 1, 2, and 5
cut -c 1-5,7- file # Extract all columns except 6
DESCRIPTION
[file...]" delimiter character ( see delim)" with the -f option. Lines with no delimiters are passwd through untouched"
Cut extracts one or more fields or columns from a file and writes them on standard output. If the -f flag is used, the fields are sepa-
rated by a delimiter character, normally a tab, but can be changed using the -d flag. If the -c flag is used, specific columns can be
specified. The list can be comma or BLANK separated. The -f and -c flags are mutually exclusive. Note: The POSIX1003.2 standard requires
the option -b to cut out specific bytes in a file. It is intended for systems with multi byte characters (e.g. kanji), since MINIX uses
only one byte characters, this option is equivalent to -c. For the same reason, the option -n has no effect and is not listed in this man-
ual page.
