I'm trying to create a date field from a numeric field and can't seem to get the syntax correct and can't find any help on line.

Thanks. We'll let you know when a new response is added.

Let’s say that we have a numeric field, where July 26, 2007 would be 20070726.

DB2 for Linux/Unix/Windows: DATE(TRIM(CHAR(numericField/10000)) || TRIM(CHAR(MOD(numericField/100),100)) || TRIM(CHAR(MOD(numericField),100)))

DB2 for iSeries/zSeries: DATE(VARCHAR(numericField/10000) || VARCHAR(MOD(numericField/100),100) || VARCHAR(MOD(numericField,100))

Oracle: TO_DATE(TO_CHAR(numericField),’YYYYMMDD’)

Another interesting way to do it in DB2: DATE(’0001-12-31′) + (numericField/10000 – 2) YEARS + MOD(numericField/100,100) MONTHS + MOD(numericField,100) DAYS
