Thanks, David. With the understanding that I don't know SSIS syntax, would (DT_DATE)((DT_STR,10,1252)SUBSTRING(Date,2,10) do the same thing or do you really have to do the character by character conversion using individual SUBSTRING(pos,1) like you did?
SSIS has no HEX to string conversion functionality, only integer to HEX.
Typical MS :angry:

Ok... thanks for the info, David.

Since you know me, it'll probably come as no surprise to you that I look at this as yet another reason for me to avoid SSIS. 😀

Doesn't have to actually be that long. Once you have the human readable string, here's the SSIS code to get it into a date:
(DT_DATE)((DT_STR,10,1252)REPLACE(REPLACE(REPLACE('0x323031342D30342D3037', '0x', ''), '2D', '-'), '3', ''))

EDIT: you might or might not need the REPLACE that turns 2D into a dash. You can test that...

Heh... even with that, I'm still hating SSIS for this type of stuff. 😉

2014-04-03 is the result string. Why is that a problem?

Because it doesn't, it produces 2014-04-0

Then repeat the (DT_STR,10,1252) between the replace functions until you find which one shortens it.

why not just convert the date to a string on the source select - converting to a format that SSIS knows well will then make the conversion to date straightforward.

And if the source is not a select (where you could change the format) then passing it through a c# script component would make it a lot easier to do the conversion than trying to mess around with a data conversion task - which if it needs to be changed going forward will be another pain to get right.

Or... you could do it in T-SQL and not have to worry about SSIS or C#. 😉 Maybe even a persisted computed column on the table might work, eh?

This was the answer. Thanks to everyone who jumped in with ideas.

After a couple days battling SSIS to get this to work, I looked up data type conversions in MySQL and set the conversion in the source.

Ultimately, this probably should have been the first thing I tried. I appreciate everyone's ideas though, it was helpful and I learned a lot about conversions in SSIS.
