Calling two functions one after other is failing in bash/sqlplus - linux

Question

I have two functions- ABC, XYZ. ABC deletes some rows in table1 as user1 and XYZ drops some users as DB User. First I am calling ABC and then XYZ. ABC function is being executed but at XYZ it is failing- "XYZ: command not found"
function ABC
{
sqlplus -s $ur1/$pwd#$SID << EOF
delete from table1 where row_name = 'A1';
delete from table2 where row_name = 'A2';
exit
EOF
}
function XYZ
{
sqlplus eip_dba/eip_dba$result#${input} << eof
set timing off
set serveroutput on size 10000
set feedback off
spool xyz_$input.out
drop user usr1 cascade;
drop user usr2 cascade;
drop user usr3 cascade;
commit;
exit
eof
}
ABC
XYZ
bash-3.2$ ./db_test.sh
2 rows deleted.
2 rows deleted.
./db_test.sh: line 100: XYZ: command not found
Please let me know what went wrong.
Thanks in advance.

Answer 1

Try removing the whitespace before EOF
function ABC
{
sqlplus -s $ur1/$pwd#$SID << EOF
delete from table1 where row_name = 'A1';
delete from table2 where row_name = 'A2';
exit
EOF
}
I tried this in a sample program and it fixed the problem.

Answer 2

The format of here-documents is:
<<WORD
here-document content ...
here-document content ...
here-document content ...
WORD
WORD can be any label you like, but the end marker must be the only thing on the line, no whitespaces before or after.
In your example functions you are using eof and EOF as labels, you should remove the space characters from in front of them so that they are really at the beginning of the line, like this:
function ABC
{
sqlplus -s $ur1/$pwd#$SID << EOF
delete from table1 where row_name = 'A1';
delete from table2 where row_name = 'A2';
exit
EOF
}
function XYZ
{
sqlplus eip_dba/eip_dba$result#${input} << eof
set timing off
# ... and so on ....
eof
}
That is, the ending EOF and eof are right at the beginning of the line, with no trailing spaces either.
