You can do the same thing in Oracle as you did in Informix. Create range partitions for 0-9 and use your mod 10 on the key. I believe you will have to add a column in the table to hold the mod number and make that the partitioning column.

HTH,

We have a table with around 80 million rows. The table has been partitioned by hash as there is no clear way of partitioning depending on range etc.. The data is very unevenly distributed in these partitions. Some of them even have 3 times the number of rows as compared to the other partitions. This application is being ported from Informix to Oracle (9i R2). In informix the dba's had partitioned the table based on a function . He was taking the mod of the number ( dividing by 10 ) . The values were then placed in either of the 10 partitions ranging from 0 - 9. This really gave us very good distribution of data .Can we achieve something similar in 9i with list partitioning.

TIA Rishi
