Im trying to complete a list of jobs using SQL Querries and some "if else"
commands but im stucked in some steps. Could any of you give me some help?
-in COLUMN1 change the format 20JAN2000:00:00:00 to 20JAN2000 and exclude
every row that date is different from 20.
-extract the first character in COLUMN2 and creat COLUMN3 with that value
-in every row in which COL3=5, value in COLUMN4=value in COLUMN5
-create COLUMN7 where if COLUMN6="north" then COLUMN7 value="N" else COLUMN7
Ill be grateful for any help, thnks
