Return value inside isql to a shell variable in ksh
Hello,
I have a shell script where I am doing an isql to select some records. the result i get from the select statement is directed to an output file. I want to assign the result to a Shell variable so that I can use the retrieved in another routine.
e.g.
"isql -U${USER} -P${PASSWD} -S${SERVER} -D${DBNAME}" <<EOF>> output1
select Names from Book
... some error check from the result above...
declare @CustID varchar (50)
select @CustID = Customer ID from Customer
EOF
The CustomerID I retrieved above needs to be passed to a UNIX variable so that I can use it further down after the end of the isql.
I did look at some threads where this was questioned but most of the answers are to retreive the value from selects when doing the isql... such as
SOMEVARIABLE = `isql....
however in the above case the result from the first select would also be passed to SOMEVARIABLE... and if so then how would u extract the values that are specifically needed.
Any ideas would be much appreciated.
Thanks.

LEARN ABOUT PHP
mysql_result
MYSQL_RESULT(3) 1 MYSQL_RESULT(3)
mysql_result - Get result data
SYNOPSIS
Warning
This extension is deprecated as of PHP 5.5.0, and will be removed in the future. Instead, the MySQLi or PDO_MySQL extension should
be used. See also MySQL: choosing an API guide and related FAQ for more information. Alternatives to this function include:
omysqli_data_seek(3) in conjunction with mysqli_field_seek(3) and mysqli_fetch_field(3)
o PDOStatement::fetchColumn
string mysql_result (resource $result, int $row, [mixed $field])
DESCRIPTION
Retrieves the contents of one cell from a MySQL result set.
When working on large result sets, you should consider using one of the functions that fetch an entire row (specified below). As these
functions return the contents of multiple cells in one function call, they're MUCH quicker than mysql_result(3). Also, note that specifying
a numeric offset for the field argument is much quicker than specifying a fieldname or tablename.fieldname argument.
o $
result -The result resource that is being evaluated. This result comes from a call to mysql_query(3).
o $row
- The row number from the result that's being retrieved. Row numbers start at 0.
o $field
- The name or offset of the field being retrieved. It can be the field's offset, the field's name, or the field's table dot field
name (tablename.fieldname). If the column name has been aliased ('select foo as bar from...'), use the alias instead of the column
name. If undefined, the first field is retrieved.
The contents of one cell from a MySQL result set on success, or FALSE on failure.
Example #1
mysql_result(3) example
<?php
$link = mysql_connect('localhost', 'mysql_user', 'mysql_password');
if (!$link) {
die('Could not connect: ' . mysql_error());
}
if (!mysql_select_db('database_name')) {
die('Could not select database: ' . mysql_error());
}
$result = mysql_query('SELECT name FROM work.employee');
if (!$result) {
die('Could not query:' . mysql_error());
}
echo mysql_result($result, 2); // outputs third employee's name
mysql_close($link);
?>
Note
Calls to mysql_result(3) should not be mixed with calls to other functions that deal with the result set.
mysql_fetch_row(3), mysql_fetch_array(3), mysql_fetch_assoc(3), mysql_fetch_object(3).
