SELECT statement

I am using PHP to query a MySQL database. I want to insert a new record into a table, then retrieve the new record.

My first query inserts the data (since Org_ID is auto_increment/not null, a new ID is created). How should I structure the second query? The way I have it shown does not work since it is an improper use of the Max() function. What else would work?

$query1 = 'INSERT INTO tblorganizations
SET
Name = "$Name",
Address = "$Address",
City = "$City",
State = "$State",
PostalCode = "$PostalCode",
Referral = "$Referral",
Org_Type_ID = "$Org_Type_ID",
Affiliates = "$Affiliates",
Remarks = "$Remarks"
';

$query2 = 'SELECT * FROM tblorganizations
WHERE Org_ID = MAX(Org_ID)
';

First of all, your INSERT statement is not correct, :
$query1 = 'INSERT INTO tblorganizations
SET
Name = "$Name",
Address = "$Address",
City = "$City",
State = "$State",
PostalCode = "$PostalCode",
Referral = "$Referral",
Org_Type_ID = "$Org_Type_ID",
Affiliates = "$Affiliates",
Remarks = "$Remarks"
';

Should be:
INSERT INTO tblorganizations VALUES (NULL, '$Name', '$Address', '$City', '$State', '$PostalCode', '$Referral', '$Org_Type_ID', '$Affiliates', '$Remarks');

for the second query, PHP has a function called mysql_insert_id(), that retrieves the ID of the latest inserted row (see the PHP manual for this function), however, this works only if you use directly after your insert statement.

A workaround:
$query2 = "SELECT MAX(Org_ID) FROM tblorganizations";
$temp = mysql_fetch_row($query2);
$query3 = "SELECT * FROM tblorganizations WHERE Org_ID = ".$temp[0];

MySQL does not support subqueries yet, so that's why I used the query2...
This was done quick, so it probably isn't completely correct, but it should help you get underway....

Thanks!

mysql_insert_id() is exactly what I was looking for. I tested it and it works fine.

By the way, my syntax for query1 was correct. Check it out!

Thanks again.
