Sql null

I have a dataassist update details page linked to a MySql database. The database has all of the columns set as default NULL. But when a user updates their details and still leaves one of the NULL fields blank it it changes it from NULL to NOT NULL, but just with no information.

Is there a way to set a field as NULL if there is no data entered in the update form?? I'm assuming it's all hand coding, but maybe there is an easy string I can type in the update field?

The only reason I'm using it is one of my SQL queries is based on whether a field is NULL.

I think you can adjust the code on the update page to do what you want. Maybe post your update code and I can suggest what you might change.

I have the same issue. I would like an empty form field to be entered as null into the database not an empty string. The reason for this is that I have code elsewhere checking for null values not empty strings.

You would have to change this manually in the code.

The column type array is built with three sections... the third part is the value to insert when blank.... it will look something like:

$WA_columnTypesStr = "',none,''|',none,''|',none,''|none,none,NULL|...

the column types are separated by | and there will be one for each column referenced above like:

$WA_fieldNamesStr = "Column1|Column2|Column3|Column4|...

If I wanted Column2 to insert null when blank I would update it to:


$WA_columnTypesStr = "',none,''|',none,NULL|',none,''|none,none,NULL|...

I don't like changing code manually as this is the reason you buy extensions in the first place (so you don't have to code). I would think that I wouldn't be on my own wanting the ability to enter a null value in the database if no data was entered in the form. Perhaps this option could be considered in future versions of the extension.

Thanks for your assistance Ray.
