Group Multiple Lines on SINGLE line matching pattern

Hi Guys,

I am trying to format my csv file. When I spool the file using sqlplus the single row output is wrapped on three lines.

Somehow I managed to format that file and finally i am trying to make the multiple line on single line.

The below command is working fine but I need to pass the DBNAME as dynamic variable in shell script ... I tried this but it is not working any help ?

Code:
sed ':a;N;/\n\"ORCL \"/!s/\n/ /;ta;P;D' infile.csv

I need to pass the DB name ORCL as dyanamic variable

Code:
export DBNAME=ORCL

sed ':a;N;/\n\"$DBNAME \"/!s/\n/ /;ta;P;D' infile.csv

- but this is not working

There are umpteen ways to skin a cat ...
The single quotes prevent the expansion of the shell variable - use double quotes instead. You could also write the script incl. the expanded variable to a file, and then have sed execute that.
For me, the best way would be to tell sqlplus NOT to break the lines but print the entire row output to one line.

I tried double quotes like below
Code:
sed ":a;N;/\n\"$DBNAME \"/!s/\n/ /;ta;P;D" infile

But the script process this code as below


Code:
++ sed ':a;N;/\n"
ORCL "/!s/\n/ /;ta;P;D' infile
sed: -e expression #1, char 9: unterminated address regex
