Bash ending the variable after first space? - bash

Question

I'm building a string in Bash in a loop. The data processed by the loop from the lines in two files which are looking like this:
FIRST part of the string is a line in file 1 looking like:
SOME_PACKAGE
SECOND PART is a line of a file 2 looking like:
someFunction('some',parameters,here)
The final output has a dot between the two strings:
1 SOME_PACKAGE.someFunction('some',parameters,here)
The 1 is important here. Explaination in a second.
The string is formed in a double while loop
while read line1 ; do
while read line2 ; do
stringArray=($line2)
string=$line1.${stringArray[1]}
sqlplus -s /nolog > /dev/null 2>&1 <<EOF
connect user/password#db_instance
variable rc refcursor;
SPOOL ${line1}_${stringArray[0]}.DATA
exec :rc := $string;
print rc;
spool off
exit
EOF
done < file2.txt
done < file1.txt
This string is then passed to SQLPlus, and SQLPlus should exit a command like this:
SQL> variable rc refcursor;
SQL> exec :rc := SOME_PACKAGE.someFunction('some',parameters,here);
SQL> print rc;
Until now, everything was working fine. But I got a more complicated parameters next to the someFunction. Now it looks like this:
SOME_PACKAGE.someFunction('some',parameters,here,'and 2 more',NULL)
It seems that the variable passed to SQL*Plus ends on the first space... So it looks like:
SOME_PACKAGE.someFunction('some',parameters,here,'and
From what I know I shouldnt pass spaces in variables, or if I want to do this, I should wrap them in quote signs: "" but where should I put those quote signs to pass the final vatiable to SQL*Plus WITHOUT those quote signs? Or what other solution do You guys propose?

The answer was simple thanks to #arco444.
The reason all this happened was the Internal field separator, which was set to default.
What I did was the following:
I've changed the look of file2 from
1 SOME_PACKAGE.someFunction('some',parameters,here,'and 2 more',NULL)
to
1§SOME_PACKAGE.someFunction('some',parameters,here,'and 2 more',NULL)
And I added some ILS changes before and after the loop, so the final code looks like this:
oldifs=$IFS
IFS="§"
while read line1 ; do
while read line2 ; do
stringArray=($line2)
string=$line1.${stringArray[1]}
sqlplus -s /nolog > /dev/null 2>&1 <<EOF
connect user/password#db_instance
variable rc refcursor;
SPOOL ${line1}_${stringArray[0]}.DATA
exec :rc := $string;
print rc;
spool off
exit
EOF
done < file2.txt
done < file1.txt
IFS=$oldifs
Everything is working like a charm now.
