Unanswered: different data type
I wonder if the following pair will be considered as same data type or not:
char(15) - char(18)
char(15) - varchar(18)
When I link the two columns char(15) to char(18), would DB2 do casting or not?
They are not the same
char column size is what it is defined as
varchar is data size + 2 bytes I believe
And depending on the version, one will cause a scan, others will not
I believe after V6 it won't...but it's still not a good idea to have the same type of data with different definitions
Why does it?
