Shell script - use variable in loop

Question

I use following command for grant postgres db. It is working.

for tbl in `psql -qAt -c "select sequence_name from information_schema.sequences where sequence_schema = 'public';" performanceeyedev` ; do  psql -c "alter table $tbl owner to prodteam" performanceeyedev ; done

I write following script for grant postgres db. But it isn't working.

DB = 'performanceeyedev';
OWNER = 'prodteam';

for tbl in `psql -qAt -c "select sequence_name from information_schema.sequences where sequence_schema = 'public';" $DB` ;
do  psql -c "alter table $tbl owner to $OWNER" $DB ; done

for tbl in `psql -qAt -c "select table_name from information_schema.views where table_schema = 'public';" $DB` ;
do  psql -c "alter seq $tbl owner to $OWNER" $DB ; done

It make following result

./grant.sh: line 1: DB: command not found
./grant.sh: line 2: OWNER: command not found
