Problem in passing IFS array to SQL Query
Hi,

I have created a shell script that reads line from text file and insert into DB table. I have used IFS to separate the line text. Looks IFS is splitting text properly but while passing one of the values that has special characters in it to query, it is giving weird issue. Below is my script looks like

Code:
IFS.OLD=$IFS
IFS='#'
while read line
do
read -r -A a <<< "$line"
echo "flag is- ${a[0]}"
if [ "${a[0]}" = "Flag" ];
then
echo "Header"
elif [ "${a[0]}" = "NU" ];
then
echo "User - Insert"
echo "company is- ${a[4]}"
sqlplus -s $DB_PATH  <<EOF
set head off feedback off
INSERT INTO USERS (EMAIL, FULL_NAME, CONTACT_PHONE_NUMBER,COMPANY, USER_ID) VALUES ( '${a[1]}', '${a[2]}','${a[3]}','${a[4]}',999527 );
commit;
exit;
EOF
fi

Below is my text file data
Code:
Flag#NEW#EMAIL#Name#Phno#Comp#***
NU#john@gmail.com#John Mathew#1122333#A&N Services, Inc.

when I run the script, output is coming as below

Code:
flag is- Flag
Header
flag is- NU
User - Insert
company is- A&N Services, Inc.
 Enter value for n: old   1: INSERT INTO USERS (EMAIL, FULL_NAME, CONTACT_PHONE_NUMBER,COMPANY, USER_ID) VALUES ( 'john@gmail.com', 'John Mathew','1122333','A&N Services, Inc.',999527 )
 new   1: INSERT INTO USERS (EMAIL, FULL_NAME, CONTACT_PHONE_NUMBER,COMPANY, USER_ID) VALUES ( 'john@gmail.com', 'John Mathew','1122333','Acommit; Services, Inc.',999527 )

I really do not understand why it is showing output like this but I investigated and found that this issue is coming due to the parameter COMPANY in the query. It has special characters. If I remove and change to simple text then it is not giving this issue and record is inserting successfully. Please suggest if any solution.

data::phrasebook::sql::query

Data::Phrasebook::SQL::Query(3pm)			User Contributed Perl Documentation			 Data::Phrasebook::SQL::Query(3pm)

NAME

       Data::Phrasebook::SQL::Query - Query Extension to the SQL/DBI Phrasebook Model.

SYNOPSIS

	   my $q = $book->query( 'find_author' );
	   my $q = $book->query( 'find_author', 'Dictionary' );

DESCRIPTION

       An extension to the SQL class to specifically handle the DBI interface for each query requested.

CONSTRUCTOR

   new
       Not to be accessed directly, but via the parent Data::Phrasebook, by specifying the class as SQL.

METHODS

   sql
       Get/set the current "sql" statement, in a form suitable for passing straight to DBI.

   sth
       Get/set the current statement handle.

   args
       Return list of arguments that will be used as bind parameters to any placeholders. Any given arguments will replace the whole list.

       Returns list in list context, arrayref in scalar.

   order
       As for "args", but regarding the corresponding list of argument names.

       The assorted "order_XXX" methods are supported as for "args_XXX".

   dbh
       Get/set the database handle.

PREPARATION 
/ EXECUTING METHODS
   execute
       Executes the query. Returns the result of "DBI::execute".

       Any arguments are given to "order_args" with the return of that method being used as arguments to "DBI::execute". If no arguments, uses
       those already specified.

       Calls "prepare" if necessary.

   order_args
       Given a hash or hashref of keyword to value mappings, organises an array of arguments suitable for use as bind parameters in the order
       needed by the query itself.

   prepare
       Prepares the query for execution. This method is called implicitly in most cases so you generally don't need to know about it.

   rebind
       Rebinds any bound values. Lets one pass a scalar reference in the arguments to "order_args" and have the bound value update if the original
       scalar changes.

       This method is not needed externally to this class.

DELEGATED METHODS

       Any method not mentioned above is given to the statement handle.

       All these delegations will implicitly call "prepare".

SEE ALSO

       Data::Phrasebook, Data::Phrasebook::SQL.

SUPPORT

       Please see the README file.
