  Hello Jeremy,
 You are right about:   char tvi_char[MAXDATEFIELDS];
 I have already tried this and didn't work too, it keeps giving the index
error!

 About:   if (sscanf(str, " ( %s , %s )", tvi_char, tvf_char) != 2)
 I test tvi_char and tvf_char with StringToDateADT(tvi_char). Just date
types are allowed!
 Any other suggestions?? Thanks!

Just glancing at this, a couple things stand out to me:

What are you doing here?  This is completely broken.  I think you meant to
say:

char *tvi_char;

tvi_char = palloc(MAXDATEFIELDS);

Or:

char tvi_char[MAXDATEFIELDS];

and no palloc.

Same as above.

This is asking for trouble if arbitrary input can be fed to this.

Hope this helps.

The ways are fair to his roaming feet,And the skies are sunlit for him.
As sharply sweet to my heart he seemsAs the fragrance of acacia.
My own dear love, he is all my dreams --And I wish he were in Asia.    -- Dorothy Parker
