When working with dates, the odds are pretty good that you will need access to today’s date. I have several books and have looked all over the IBM site, finally I have found the correct statement to access the current date. Thank you for publishing what should be so much easier to find.

Daniel: That’s OK, I was busy too.

No, I have not contacted IBM. My thought was that being so new to PHP, that I was making a rookie mistake. I will send this question on to them now.

Thanks.

Ray,

Sorry for the delayed reply, have you contacted the IBM maintainers of the ibm_db2 PECL extension about this?

Attempting to insert or update a row in a table for credit cards that has the card number as varchar and expiration date as DATE. Both may be NULL. When db2_execute is passed NULL as the parameter as in “expdate = NULL”, I get an SQL0180N error “The syntax of the string representation of a datetime value is incorrect.” The SQL statement can be cut and pasted into the Command Center and it is valid. Setting both columns to actual values works so that leaves me wuth the question, How do you set a nullable column to NULL using db2_* functions from PHP ? I know I can change the string and parameters being passed, but NULL is a valid keyword and it should be processed as such.

Thanks in advance.

Hi Fakhre,

You have an error in your SQL syntax. You’re missing a condition after the third LIKE clause: “com.comp_id like [missing ‘%$txtFind%’ here] or”

Hi Mike,

Yes, that DB2 insert will fail, whereas the MySQL one will succeed with unexpected results. :)
