Hi PHPR community,
Is it ok to use SQL variables on creating SQL on the Query page? It is a Custom View named: formdetail_subcat

SELECT s1.id

FROM subcategory AS s1

WHERE (s1.id NOT IN(SELECT formdetail.subcategory_id FROM formdetail WHERE formdetail.formhf_id=':formhf_id' AND formdetail.category_id=':category_id'))

AND (s1.category_id = ':category_id')

UNION

SELECT s2.id

FROM subcategory AS s2

WHERE s2.id = ':subcategory_id'


NOTE: Forums suggest to use views to use UNION since it is not compatible with PHPR.
The return is just single column with IDs. Example:



3

17

73

26


And, then, I used it on the WHERE of the Lookup Wizard:



WHERE subcategory.id IN (SELECT * FROM formdetail_subcat)


But, it gives the following error:



Technical information

Error type 256

Error description Table 'wtmc.formdetail_subcat' doesn't exist

URL localhost/formdetail_edit.php?

Error file ...\output\connections\Connection.php

Error line 611

SQL query SELECT `id`, `name`, `category_id` FROM `subcategory` WHERE ( ( subcategory.id IN (SELECT * FROM formdetail_subcat) ) and ( (category_id=3) ) )

Hi PHPR community,
I still want to know why the Custom View created does not exist when application is run.
I did create a custom view from within MySQL. PHPR can see it. But the Custom View I created from within PHPR are not showing in MySQL. Thus probably making PHPR pop an error message: "Table ... not existing".
For now, I did a little twist on the SQL query without the use of UNION or even a Custom View.



subcategory.id NOT IN(SELECT formdetail.subcategory_id FROM formdetail

WHERE formdetail.formhf_id=':formhf_id'

AND formdetail.category_id=':category_id'

AND formdetail.subcategory_id NOT IN(':subcategory_id'))

You are confusing database views and custom views. Custom Views are PHPRunner thing, just merely a named SQL Query.
If you need to work with something like UNION you need to create a view in the database itself.

Hi Sergey,
Thank you for your reply. But how come the Custom View "does not exist" when I ran my application?
I will figure out how to pass SQL variables from the SQL statement to the MySQL database view.
You think I will require procedure for this?
You have examples somewhere on PHPR website, forums or blog so I can see how its use?

First create the view in MySQL without using any variables. Then add this view to the project and use those variables in WHERE clause.
But formdetail_subcat needs to be a real view in MySQL and not a custom view.

Hi Sergey,
Noted and thank you for the instruction. I will give them a try.
