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

Does the script threw any error..? If so please post the same. And there is a semicolon miss in your code exit;
Below is a sample code to login to sqlplus and querying by passing a parameter
Code:
#!/bin/bash
line=sysdate
cnt=2

sqlplus -s user_t/user_t@ORADEV <<EOF > $(echo $PWD)/outfile.txt
select $line from dual;
select * from emp where emp_id='$cnt';
exit;
EOF

The mistake I did was:

I created the text file (table_list.txt) from windows. Now I created from UNIX and it works.

The simple mistake costed me a day. Smilie

Thanks for all your help.
