db2

问题 I have a query from mysql that has been running on a table I recently migrated to DB2. The query now fails on DB2 due to the line below, saying that DATEDIFF cannot be found. I'm assuming only because this isn't a valid function on db2. Is there an equivalent to this on DB2 that will maintain performance as well as function? SELECT DISTINCT LEAST(180, DATEDIFF(curdate(), start_date)) as days FROM table2 where expire_date > curdate() 回答1: I use the DAYS() function to convert the dates to

问题 I'm attempting to isolate eight digits from a cell that contains other numbers as well as text and no rhyme or reason to where it is placed. An example return would look something like this: will deliver 11/07 in USA at 12:30 with conf# 12345678 I need the conf# only, but it could be at the end, beginning, middle of the string and I don't know how to isolate it.
