Example

The following expression uses SYSDATE to find orders that have shipped in the last two days and flag them for insertion. Using DATE_DIFF, the

Data Integration Service

subtracts DATE_SHIPPED from the system date, returning the difference between the two dates. Because DATE_DIFF returns a double value, the expression truncates the difference. It then compares the result to the integer literal 2. If the result is greater than 2, the expression flags the rows for rejection. If the result is 2 or less, it flags them for insertion.

IIF( TRUNC( DATE_DIFF( SYSDATE, DATE_SHIPPED, 'DD' ), 
0 ) > 2, DD_REJECT, DD_INSERT
