Your suggestion is good, but let's first see of we can understand your problem. Is the input data clean: is the origin of your data a source where prepopulated combo-boxes are used? If so, then your query will be a simple INSERT statement where FK relations are observed by default. If the source could be from anywhere, then you are likely to need multiple SQL statements, each checking the presence of the fields which are referenced. Hope this helps

db2_prepare
DB2_PREPARE(3) 1 DB2_PREPARE(3)
db2_prepare - Prepares an SQL statement to be executed
SYNOPSIS
resource db2_prepare (resource $connection, string $statement, [array $options])
DESCRIPTION
db2_prepare(3) creates a prepared SQL statement which can include 0 or more parameter markers ( ? characters) representing parameters for
input, output, or input/output. You can pass parameters to the prepared statement using db2_bind_param(3), or for input values only, as an
array passed to db2_execute(3).
There are three main advantages to using prepared statements in your application:
o Performance: when you prepare a statement, the database server creates an optimized access plan for retrieving data with that
statement. Subsequently issuing the prepared statement with db2_execute(3) enables the statements to reuse that access plan and
avoids the overhead of dynamically creating a new access plan for every statement you issue.
o Security: when you prepare a statement, you can include parameter markers for input values. When you execute a prepared statement
with input values for placeholders, the database server checks each input value to ensure that the type matches the column defini-
tion or parameter definition.
o Advanced functionality: Parameter markers not only enable you to pass input values to prepared SQL statements, they also enable
you to retrieve OUT and INOUT parameters from stored procedures using db2_bind_param(3).
PARAMETERS
o $connection
- A valid database connection resource variable as returned from db2_connect(3) or db2_pconnect(3).
o $statement
- An SQL statement, optionally containing one or more parameter markers..
o $options
- An associative array containing statement options. You can use this parameter to request a scrollable cursor on database servers
that support this functionality. For a description of valid statement options, see db2_set_option(3).
RETURN VALUES
Returns a statement resource if the SQL statement was successfully parsed and prepared by the database server. Returns FALSE if the data-
base server returned an error. You can determine which error was returned by calling db2_stmt_error(3) or db2_stmt_errormsg(3).
EXAMPLES
Example #1
Preparing and executing an SQL statement with parameter markers
The following example prepares an INSERT statement that accepts four parameter markers, then iterates over an array of arrays con-
taining the input values to be passed to db2_execute(3).
<?php
$animals = array(
array(0, 'cat', 'Pook', 3.2),
array(1, 'dog', 'Peaches', 12.3),
array(2, 'horse', 'Smarty', 350.0),
);
$insert = 'INSERT INTO animals (id, breed, name, weight)
VALUES (?, ?, ?, ?)';
$stmt = db2_prepare($conn, $insert);
if ($stmt) {
foreach ($animals as $animal) {
$result = db2_execute($stmt, $animal);
}
}
?>
