<p class="MsoNormal"><span style="color:#1F497D">The problem stems from the column being altered from an integer4 to an integer1. Sadly there was some data which exceeded the limit of an integer1 item.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="color:#1F497D">The alter table alter column should have picked this up … but didn’t. Strangely this appears to be also related to the size of the table. If I do a simple test on a table with 1 row the alter table does pick
up the offending integer overflow.<o:p></o:p></span></p>
