mysql problem

[Jorgen Andersson]

The message can't be much clearer than that. You're trying to insert a null value into a key column. To help you further we need more info, such as the table structure, the stored procedure and how it's used.

Put a break point in the code and check each objcom_reg. value, see if a string value is not initialised and is therefore null.

Hasn't really worked out the array thingy yet!

<edit>You are setting dbparamcoll twice but with different parameters. The first setting is never used.</edit> Ok, it's official, I'm blind like a bat.

actually there are two arrays with different casing, and it is the second one that isn't used. :)

Crap, That's a sign that I need to go home now.

I suspect your insertreg procedure is not providing a value for a key column.
