Validate dates before conversion, aka. ISDATE() equivalent

Question

DB2 version is 9.7.0.7

I have a flat file, and need to validate fully prior to insert into a production table. For analysis, I\'ve parsed it into a table where all

Answer 1

You can do it with the PureXML extension as follows:

SELECT
 XMLCAST(XMLQUERY('string($D) castable as xs:date' PASSING mycolumn as D ) AS INT)
FROM 
 mytable

which will return 1 or 0.
