Yes, mysql correctly treats an empty string "" and null as separate
values. When you put nothing in a insert field, in witango, it inserts
an empty string.

To insert a “NULL” in a field in MySQL?
Seems like a lot of extra work, but I will do it if I need to.
Thanks

This works in a NON Quoted field. You will have to experiment. I
have done it before but don't have time to look up old code at the
moment.

Hi Robert,
That would be a great idea, but I only see the “Include Empty”
option in the READ action. I don’t see it in the WRITE or UPDATE
action. I also see it in the “Select Rows Matching These Criteria”
part of the UPDATE action.
I only see “Quote Value” in the WRITE and UPDATE action.
Maybe I am missing something.

I believe you can check to NOT INCLUDE if empty. If you put an empty
arg in there, witango will write an empty string "". if the field is
NOT included, it will be null.

Hi,
I am completing work adjusting an app that was originally written to
work with R:Base to now work with MySQL as well. Whenever I write or
update a record in R:Base, all empty text fields are written with a
NULL. It appears that this is not happening in MySQL, I can set a
MySQL text field to <@arg xxxxx> where <@arg xxxxx> is empty, but
MySQL doesn’t write a NULL to the field.
Is this correct?
If so, is my only option to write a \N in the field if I am using
MySQL?
Thanks in advance.
