Hi,

One way is to do the following:

1. Export the table for backup purposes
2. Create a temp table containing the primary key and column to be altered.
3. update original_table set number_column=null;
4. alter original_table <table_name> MODIFY (column(3,2));
5. Update column from temp table. (Assuming all the data in temp table will go in number(3,2) format.

Hi,

i have a column set to number(3). However this needs to be changed to number (3,2). But i cannot do a straight alter table as there is data in the column.

how can i get round this?

cheers
