Bug description:Null values for insert/update statements
Description:
------------
Actually using PHP 5.4.0.3 but this was not in the drop down list above.
Null is a perfectly valid value for a column. However, PHP fails to submit
the correct values when it builds the SQL query and submits it to the
postmaster.
I don't have this problem with Java and the Postgres jdbc driver.
Consider the following DDL:-
create table table_a (
tablea_id serial not null primary key,
col_a varchar(20),
col_b integer,
col_c boolean default false);
In my class for table_a I have:-
update table_a set col_a = 'this->colA', col_b = this->colB,
col_c = this->colC where tablea_id = $something;
In my action I might set a value -- setcolA('some value');
If this->colB IS NULL, then PHP doesn't detect this fact, generates the
following SQL which fails because of syntax errors.
update table_a set col_a = 'some value', col_b = , col_c = where tablea_id
= 3;
It should generate:-
update table_a set col_a = 'some value', col_b = null, col_c = null where
tablea_id = 3;
The failure to detect boolean's and treat them appropriately is another
pain in the neck. You are using pg_query, you KNOW it's a Postgres
database, you should KNOW that Postgres creates boolean columns as char(1),
and that it uses a 't' to represent "true" and a 'f' to represent "false".
To overcome this failure I had to do the following in my class:-
$my_bool = this->colC? 't' : 'f';
and then use '$my_bool' instead of this->colC in the insert and update
statements.
Imagine if you had dozens of boolean type columns in a table. A nightmare.
It is quite common in applications where users belong to groups and a group
has a set of privileges, and those privileges are usually held as boolean
value's.
