I had the order by just before the into cursor line, I took it out as it was causing the issue. I do normally include table.field name but as I was testing I didn't bother, I was actually building up the select code from a simple 2 fields to try to get to the bottom of it.
order by BTR_link
into cursor temp2

>>I am toying with the idea of a secondary select on the result, but I'd rather do the job in 1 query as I have 5 such queries to do and they are looking at reasonably large data sets, so better off not running commands that I don't have to.
>>The error I get back is "SQL: Order by clasue is invalid", this is for engine behaviour set to 70 or 80. If I set it to 90 I get a syntax error and then this error, however I think that the engine behaviour 90 syntax error is not related to the order by.
