Hi All.

I have written an application that will read a number of CSV files and insert the data from them into a table (roughly 60column).  And in total there will eventually be 46million records.

Now, i want to apply a clustered index to an int field but i dont know whether to apply it to the empty shell PRE-insert, or to apply it in bulk when the insertions have finished.

I know that it will take a long time either way, if i do it during insertion it will take longer to finish the insert processes, if i do it at the end it will take about 10 hours to index, i just want to make sure the integrity of the table remains 100% - im worried that if the indexes are written during insertion that something might go wrong - paranoia

Any suggestions?
