[cfaussie] Re: queryAddRow

[Dale Fraser]

Cool,

Thanks again, I need to write a modified version to handle my situation.

You should put it on cflib

I think I understand Andrews question, but they way you did it adds the
extra ability to insert lots of extra rows to the end of a query and then
fill them later.

Yes that's right dale.

With this function also, all the columns don't have to be passed in either.
If it finds the column it the "rowData" param it populates it otherwise it
is just left empty.

Using the array function is going to be faster than looping over recordsets
also.

Thanks Steve,

I think I understand that.

You are converting each column to an array inserting a row into that array
and adding that column back to a new query, correct?
