Using GREP in IF Statement

Hello All,
I have 2 different pieces of code, I am confused why the Code1 is giving me the correct result where as the Code2 is not giving me correct result. It gives me always result as "Failure" irrespective of the "ERROR" word exists in logfile or not. may I know the reason why? I am using Bash shell in Linux OS.

Code1:

Code:

#!/bin/bash
sqlplus -s FCSDWH_STG/FCSDWH_STG@dwdev <<EOF > /home/infrmtca/bin/logfile
exec today_is;
EOF
        if `grep -q "ERROR" /home/infrmtca/bin/logfile` ;
        then
                echo "Success"
        else
                echo "Failure"
        fi

Code2:

Code:

#!/bin/bash
sqlplus -s FCSDWH_STG/FCSDWH_STG@dwdev <<EOF > /home/infrmtca/bin/logfile
exec today_is;
EOF
        if [ `grep -q "ERROR" /home/infrmtca/bin/logfile` ]
        then
                echo "Success"
        else
                echo "Failure"
        fi

My content of "/home/infrmtca/bin/logfile" is below

Code:

BEGIN today_is; END;

      *
ERROR at line 1:
ORA-06550: line 1, column 7:
PLS-00905: object FCSDWH_STG.TODAY_IS is invalid
ORA-06550: line 1, column 7:
PL/SQL: Statement ignored

Thank you

RBASH(1)						      General Commands Manual							  RBASH(1)

NAME

       rbash - restricted bash, see bash(1)

RESTRICTED SHELL

       If  bash  is  started with the name rbash, or the -r option is supplied at invocation, the shell becomes restricted.  A restricted shell is
       used to set up an environment more controlled than the standard shell.  It behaves identically to bash with the exception that the  follow-
       ing are disallowed or not performed:

       o      changing directories with cd

       o      setting or unsetting the values of SHELL, PATH, ENV, or BASH_ENV

       o      specifying command names containing /

       o      specifying a file name containing a / as an argument to the .  builtin command

       o      specifying a filename containing a slash as an argument to the -p option to the hash builtin command

       o      importing function definitions from the shell environment at startup

       o      parsing the value of SHELLOPTS from the shell environment at startup

       o      redirecting output using the >, >|, <>, >&, &>, and >> redirection operators

       o      using the exec builtin command to replace the shell with another command

       o      adding or deleting builtin commands with the -f and -d options to the enable builtin command

       o      using the enable builtin command to enable disabled shell builtins

       o      specifying the -p option to the command builtin command

       o      turning off restricted mode with set +r or set +o restricted.

       These restrictions are enforced after any startup files are read.

       When a command that is found to be a shell script is executed, rbash turns off any restrictions in the shell spawned to execute the script.
