COPY PENDING status
A state in which, an image copy on a table needs to be
taken, In this status, the table is available only for
queries. You cannot update this table. To remove the COPY
PENDING status, you take an image copy or use REPAIR
utility.

CHECK PENDING
When a table is LOADed with ENFORCE NO option, then the
table is left in CHECK PENDING status. It means that the
LOAD utility did not perform constraint checking.

SET is the ANSI standard for variable assignment, SELECT is not. SET can only assign one variable at a time, SELECT can make multiple assignments at once. If assigning from a query, SET can only assign a scalar value. If the query returns multiple values/rows then SET will raise an error. SELECT will assign one of the values to the variable and hide the fact that multiple values were returned (so you'd likely never know why something was going wrong elsewhere - have fun troubleshooting that one) When assigning from a query if there is no value returned then SET will assign NULL, where SELECT will not make the assignment at all (so the variable will not be changed from it's previous value) As far as speed differences - there are no direct differences between SET and SELECT. However SELECT's ability to make multiple assignments in one shot does give it a slight speed advantage over SET.
