How to Access Oracle Table through bash when it's a new create table - bash

Question

I have a simple script in bash that just return the count of a given table
The trow command through bash its like that
user>bash Bash_Script.bsh -T MyTableTthatAlreadyExists
After the conections parameters it just do that:
SQLSTRING="SELECT COUNT(*) FROM $SYBTAB;"
BATCH_ARGS=`sqlplus -S /nolog <<SQL | tail -1
connect $ORCL_USR/$ORCL_PWD#$ORCL_TNS;
alter session set nls_date_format='YYYYMMDD';
set pagesize 0 long 4096 linesize 32767 feed off head off;
$SQLSTRING
quit;
SQL`
echo "$BATCH_ARGS"
And it works. Yest it works, it returns the nummer of rows of my table.
The problem come when I create a new table MyNewTable
- The table exists in Oracle
so when I do in SQL Developer
select count(*) from MyNewTable;
return the correct nummer.
But when I throw again the unix command. It doesnt work, it doesnt return anything
user>bash Bash_Script.bsh -T MyNewTable --> return nothing
I wonder myself what I m missing, wat I m not taking account.
I thounk about Grant privileges but they both haven the same.
can anyone here help me ?
Thanks in advance, Enrique

Your script is only getting the last line of output from SQL*Plus
BATCH_ARGS=`sqlplus -S /nolog <<SQL | tail -1
If you remove the tail part:
BATCH_ARGS=`sqlplus -S /nolog <<SQL
then you'll see what is actually happening. With a table that exists, with that modification I see:
user>bash Bash_Script.bsh -T MyTableTthatAlreadyExists
Session altered.
1815
and with a table that does not exist I see:
user>bash Bash_Script.bsh -T MyNewTable
Session altered.
SELECT COUNT(*) FROM t43

ERROR at line 1:
ORA-00942: table or view does not exist
It seems you are seeing ORA-01031: insufficient privileges, so the user you are connecting as needs to have select privileges granted for the new table.
As you only want the actual count, if you swap the order of the alter and set clauses the Session altered. message will also be suppressed as feedback will be switched off by then:
BATCH_ARGS=`sqlplus -S /nolog <<SQL
connect $ORCL_USR/$ORCL_PWD#$ORCL_TNS;
set pagesize 0 long 4096 linesize 32767 feed off head off;
alter session set nls_date_format='YYYYMMDD';
$SQLSTRING
quit;
SQL`
and you'd then see, for an existing table, just:
user>bash Bash_Script.bsh -T MyTableTthatAlreadyExists
1815
making the tail unnecessary anyway.
