If I m not wrong, you are trying to execute same query for 25 column ids on a customer table at a single time.
For that your following qeury will list out column ids in abc.txt file. Correct?
Code:
sqlplus -s $ORA_CONN <<EOF
SET SERVEROUTPUT ON
SET FEED OFF
spool abc.txt
BEGIN
FOR i IN (SELECT ID FROM customer)
LOOP
DBMS_OUTPUT.put_line ( 'value ' || i.ID);
END LOOP;
END;
/
spool off
EOF
abc.txt will look like
Quote:
1
2
3
4
5
..
..
25
Now to execute same query as follows on all listed column ids, you can write a script like
Code:
#!/bin/ksh
# First list out Column ids in abc.txt file
sqlplus -s $ORA_CONN <<EOF
SET SERVEROUTPUT ON
SET FEED OFF
spool abc.txt
BEGIN
FOR i IN (SELECT ID FROM customer)
LOOP
DBMS_OUTPUT.put_line ( 'value ' || i.ID);
END LOOP;
END;
/
spool off
EOF
# Now for each data in abc.txt, execute second query in background
for myID in `cat abc.txt | xargs`
do
sqlplus -s $ORA_CONN <<EOF!
SPOOL ${rep_name}report_${rep_part}_${sysdate1}.txt;
SELECT * FROM customer WHERE col1="$myID"
AND ( col2='sumthing')
UNION
SELECT * FROM customer WHERE col1="$myID"
AND (condition);
Spool off;
exit
EOF! &
done

pdostatement.fetchcolumn
PDOSTATEMENT.FETCHCOLUMN(3) 1 PDOSTATEMENT.FETCHCOLUMN(3)PDOStatement::fetchColumn - Returns a single column from the next row of a result set
SYNOPSIS
public mixed PDOStatement::fetchColumn ([int $column_number])
DESCRIPTION
Returns a single column from the next row of a result set or FALSE if there are no more rows.
Note
PDOStatement.fetchColumn(3) should not be used to retrieve boolean columns, as it is impossible to distinguish a value of FALSE from
there being no more rows to retrieve. Use PDOStatement.fetch(3) instead.
PARAMETERS
o $column_number
- 0-indexed number of the column you wish to retrieve from the row. If no value is supplied, PDOStatement.fetchColumn(3) fetches
the first column.
RETURN VALUES PDOStatement.fetchColumn(3) returns a single column in the next row of a result set.
Warning
There is no way to return another column from the same row if you use PDOStatement.fetchColumn(3) to retrieve data.
EXAMPLES
Example #1
Return first column of the next row
<?php
$sth = $dbh->prepare("SELECT name, colour FROM fruit");
$sth->execute();
print("Fetch the first column from the first row in the result set:
");
$result = $sth->fetchColumn();
print("name = $result
");
print("Fetch the second column from the second row in the result set:
");
$result = $sth->fetchColumn(1);
print("colour = $result
");
?>
The above example will output:
Fetch the first column from the first row in the result set:
name = lemon
Fetch the second column from the second row in the result set:
colour = red
