SQL worker objects

[Das Goravani]

Sten, 

HI, and thanks for this. However, I only wanted those two things, really one thing, explained to me, what is in binds1, what is in it, it’s a list I know, what is on the lines of the list exactly…the naming indicates they are. Bind variables, but I don’t know why they need to be in a list there, and how they are syntax formulated, your code is hard to understand, it’s rich, and it’s large, I like the manuals example, it’s understandable, if only I knew what those bind variable lists do, if they have multiple lines or only one, why they are there, how they work into the SQL, all about them I need to understand. They make no sense to me as they appear in the example
