Question

I’m fairly new to SQL, but trying to write quite a complicated query, but it’s failing at the first part. I need to create a new row for a table that auto increments the ID, and immediately extract the ID to use further down the query. Have been googling for hours to try and understand this, but can’t seem to get it to work.
Here is the opening bit (which it is failing on it seems):

DECLARE @point1ID;
INSERT INTO points SET
pointName = "$pointName1",
street = "$street1",
town = "$town1",
city = "$city1",
zip = "XXX",
country = "$country1",
pointDescription = "$pointDescription1";
SELECT @point1ID = scope_identity();

I was hoping that would put the ID of the just-inserted row into the variable @point1ID, so that I could use it later on in the same TRANSACTION / COMMIT block.
What am I doing wrong here?

Thanks!

Given that you’re using the query in PHP, carry out your INSERT, then use

$insert_id = mysql_insert_id();

to get the auto-incremented ID.
