We have requirement to change a column's type (say column CC )from decimal to char. We created an empty table with char data type for the column and the following qurey populates that table
Insert into New
The original table has 86M rows and 5GB in size. I am slightly surprised that it neededs 6G of spool space to do the job even though we are populating an empty table.
Comparing with - creating and populating the table without any change , it donot need any spool space. It runs much much faster that the previous one.
Any idea to avoid spool space utilization other than fastexport and fastload?
Thanks in advance
