Passing a string variable from Unix to Sql Plus

Hi Guys,

I am trying to pass a string variable from Unix shell script to sqlplus as a parameter.

I have tried using single quotes with the variable name but it does not work. Please help me with it.

I am using BASH.

My code:

Quote:

for line in $(head -$to_line table_list.txt | tail -$no_lines)
do
echo $line
sqlplus -S -L $from_db >> $sqlscript <<EndSQL1

SELECT LTRIM(MAX(SYS_CONNECT_BY_PATH (col_name,', ')),',') FROM (
SELECT column_id,CASE WHEN data_type LIKE 'TIMESTAMP%' THEN 'TRUNC(' ||column_name || ')'
ELSE column_name END col_name FROM (SELECT * FROM all_tab_columns
WHERE table_name= '$line'
) ORDER BY column_id ) START WITH column_id = 1 CONNECT BY PRIOR column_id = column_id -1;

exit
EndSQL1

Your help is much appreciated.

Thanks,
shil

escapeshellarg - Escape a string to be used as a shell argument

SYNOPSIS

       string escapeshellarg (string  $arg)

DESCRIPTION

       escapeshellarg(3)  adds	single quotes around a string and quotes/escapes any existing single quotes allowing you to pass a string directly
       to a shell function and having it be treated as a single safe argument. This function should be used  to  escape  individual  arguments	to
       shell functions coming from user input. The shell functions include exec(3), system(3) and the backtick operator.

	On Windows, escapeshellarg(3) instead removes percent signs, replaces double quotes with spaces and adds double quotes around the string.

		- The argument that will be escaped.

RETURN VALUES

	The escaped string.
