Hi,
I need to do this where condition:

WHERE model.field IS NULL

I have tested this code on the "Where conditions" section:

model.field/is:NULL

but this doesn't work because in the script put NULL value between two apexes (i.e. 'NULL') as in the following code:

wrong mysql condition: WHERE model.field IS 'NULL'

Someone could help me please?

Thanks
Francesco

Hi Francesco,

Please try:

model.field/is

Or

model.field/is:{value:null}

Best regards,
Max

They don't work. I have this error:

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ''' AND `ISCR`.`id_user` IS ''' at line 1 SQL=SELECT COUNT(`USRS`.`id`) AS `USRS.count` FROM `#__users` AS `USRS` LEFT JOIN `#__chronoforms_iscrizione_gara` AS `ISCR` ON `USRS`.`id` = `ISCR`.`id_user` WHERE `ISCR`.`id_gara` IS '' AND `ISCR`.`id_user` IS '';

I tested also:

model.field:

This code run but doesn't give back Null fields.

I ran the sql string on phpmyadmin, with the right condition IS NULL and it give me the attended results

Hi Francesco,

What about the 2nd code block, what error does it return ?

You may try this code in the where conditions:

<?php
return array("Model.field", null, "is");

Hi Max,

the code

model.field/is:{value:null}

give back this error:
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ''' AND `ISCR`.`id_user` IS ''' at line 1 SQL=SELECT COUNT(`USRS`.`id`) AS `USRS.count` FROM `#__users` AS `USRS` LEFT JOIN `#__chronoforms_iscrizione_gara` AS `ISCR` ON `USRS`.`id` = `ISCR`.`id_user` WHERE `ISCR`.`id_gara` IS '' AND `ISCR`.`id_user` IS '';

i tested your last code:

<?php
return array("Model.field", null, "is");

but this give me back something as:
WHERE `Model`.`field` = '' AND `Model`.`` = '' AND `Model`.`is` = '';
so CCv6 read the 3 parameters of return array as fields of db table.

CCv6 seem to insert always the parameter between two apexes and the last format of return array is wrong.

Thanks again
Francesco

Hi Francesco,

Ok, the last code I posted has a small problem, please test this one:

<?php
return [["Model.field", null, "is"]];

Best regards,
Max

Hi Max,
also with this code I have always the same error about the apexes:

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ''' AND `ISCR`.`id_user` IS ''' at line 1 SQL=SELECT COUNT(`USRS`.`id`) AS `USRS.count` FROM `#__users` AS `USRS` LEFT JOIN `#__chronoforms_iscrizione_gara` AS `ISCR` ON `USRS`.`id` = `ISCR`.`id_user` WHERE `ISCR`.`id_gara` IS '' AND `ISCR`.`id_user` IS '';

I have always back

WHERE model.field IS ''

but i need of

 WHERE model.field IS NULL

.

Could be a bug?

thanks
Francesco

With the patch file and this code in where condition section work perfectly!

model.field/is:{value:null}

thx
Francesco
