Question

Hello all and thanks for the help,
I need to write every row from one of my t-sql table columns into an xml file as a child. my current code OVER writes the last entry as it loops. The result should look like

(desired result)
<array> 
<element>data1</element>
<element>data2</element>
<element>data3</element>
<element>data4</element>
<element>data5</element>
</array>

Not (currently)

<array>
<element>data5</element> (the last entry in table column)
</array>

What am I missing ?
Thanks Again your time is much appreciated.

You code is creating the file at the start of each iteration of the while loop (as well as closing an flushing it at the end of the while loop). Move that code outside the while loop and you’ll have better results.
