Java Assign SQL result in shell variable
Hi

im trying to assign the result of the db2 command to a variable inside a shell script...
: tab_cnt=`db2 "select count(*) from syscat.tables where tabname = 'ABC' and tabschema = 'MATT01'" |head -4|tail +4|cut -c 11`

: echo $tab_cnt

when i echo im getting a blank value.. im expecting value 0...

if i try the same command outside the script
: db2 "select count(*) from syscat.tables where tabname = 'ABC' and tabschema = 'MATT01'" |head -4|tail +4|cut -c 11
: 0 (i get 0... expectd)

I found that if i remove the " |head -4|tail +4|cut -c 11" from the db2 command im getting an output of
tab_cnt=
1
-----------
0

1 record(s) selected.


can smbdy explain why is this happening ..n what can be done for getting the query results in a variable...


thanks in advance...

This may work for you:
Code:
 
tab_cnt=`db2 "select count(*) from syscat.tables where tabname = 'ABC' and tabschema = 'MATT01'" | awk '/=$/ { getline; print; }'`
