altering the column of a table

edited Jan 16, 2014 3:54AM in Database Administration (MOSC) 6 commentsAnswered

version of the database is 11.2.0.2

i have one table "M1_TASK_TYPE" and  in that one of the column is "M1_SCHED_PRIORITY".

the column M1_SCHED_PRIORITY whose datatype length is  NUMBER(13,4)

I need to change the data type length  to (NUMBER(13,2).<--So we would be reducing the decimal precision by two places.

--->Since there is already data in this column

Do you know the best way to go about this?  Could you please provide me the steps to perfom it.

Howdy, Stranger!
