Question

I am looking over some code that another programmer made where he calls a stored procedure. Before calling it, he creates an Array with the parameters needed for the stored procedure to query the table. He creates the array like this:

param = Array("@Name", 3, 8, "Tom", _
            "@Age", 3, 8, 28, _
            "@City", 100, 200, "Toronto)

The stored procedure uses @Name, @Age and @City to query the table.

My question is, what are the numbers in between for?

Answer 1

It looks like:

@Name = parameter name

3 = adInteger

8 = length

“Tom” = value

@Age= parameter name

3 = adInteger

8 = length

28 = value

@City= parameter name

100 = length

200 = adVarChar

“Toronto = value
