In postgresql I have a table which I need to add a new column. the original table ddl is belowing:
CREATE TABLE survey.survey_response (
id uuid NOT NULL DEFAULT uuid_generate_v4(),
survey_id uuid NOT NULL,
survey_question_id uuid NULL,
user_id varchar(256) NULL,
device_id varchar(256) NULL,
user_country varchar(100) NULL,
client_type varchar(100) NULL,
product_version varchar(100) NULL,
answer text NULL,
response_date timestamptz NOT NULL DEFAULT now(),
survey_category varchar(100) NULL,
tags varchar(250) NULL,
tracking_id uuid NULL,
CONSTRAINT survey_response_pkey PRIMARY KEY (id)
)
WITH (
OIDS=FALSE
) ;
Then I alter the table to add a new column:
alter table survey.survey_response add column system_tags varchar(30) ;
But after that I found my instert statement cannot make change to this new column, for all the original columns it works fine:
INSERT INTO survey.survey_response
(id, survey_id, user_id, tags, system_tags)
VALUES(uuid_generate_v4(), uuid_generate_v4(),'1123','dsfsd', 'dsfsd');
select * from survey.survey_response where user_id = '1123';
The "tags" columns contains inserted value, however, system_tags keeps null.
I tested the above scenario in my local postgreSQL 9.6, any ideas about this strange behavior? Thanks a lot
-----------------update----------
I found this survey.survey_response table has been partitioning based on month, So my inserted record will also be displayed in survey.survey_response_y2017m12. but the new system_tags column is also NULL
CREATE TABLE survey.survey_response_y2017m12 (
id uuid NOT NULL DEFAULT uuid_generate_v4(),
survey_id uuid NOT NULL,
survey_question_id uuid NULL,
user_id varchar(256) NULL,
device_id varchar(256) NULL,
user_country varchar(100) NULL,
client_type varchar(100) NULL,
product_version varchar(100) NULL,
answer text NULL,
response_date timestamptz NOT NULL DEFAULT now(),
survey_category varchar(100) NULL,
tags varchar(250) NULL,
tracking_id uuid NULL,
system_tags varchar(30) NULL,
CONSTRAINT survey_response_y2017m12_response_date_check CHECK (((response_date >= '2017-12-01'::date) AND (response_date < '2018-01-01'::date)))
)
INHERITS (survey.survey_response)
WITH (
OIDS=FALSE
) ;
If I run the same scenario in a non-partition table then the insert works fine.
So do I need any special settings for alter table for partition table?
Old thread but you need to drop and create again the RULE to fix the issue.

I'm executing below query in postgres 12.11
Table structure as below:
CREATE TABLE pdb_interface.schedule (
id uuid NOT NULL DEFAULT uuid_generate_v4(),

update schedule
set daily_frequency = 12
where id = 'f2f0ba60-f8b1-49ae-a82c-aaddb1a1834b'
The column "id" is of uuid and value is present in the table . However while executing above query, it is giving below error
SQL Error [XX000]: ERROR: no conversion function from character varying to uuid
Is there any work around for the same
My question is similar to the one posted earlier in the Community. questions/62936399/error-sql-state-42703-while-trying-to-insert-data-into-my-table
In PostgreSQL, I'm trying to run CREATE Table Statement so that I can continue with inserting values. Although my CREATE statement fails so I can't get on with INSERT statement. The error message that keeps coming up ERROR: relation "eventrequest" does not exist
SQL state: 42P01
I have re-did the entire CREATE Statement twice although the error message does not change.

I need Help with implementing a database in SQL Developer. I tried to implement date constraints but it doesn't work the way I want to.
Here is Office Table:
CREATE TABLE Office (
Office_ID varchar2(7) PRIMARY KEY NOT NULL,
Office_AddressLine varchar2(50) NOT NULL,
Office_PostCode varchar2(8) NOT NULL,
Office_Telephone varchar2(11),
Office_Email varchar2(30), PRIMARY KEY(Office_ID),

Here is Employee Table:

Emp_AwardingBody varchar2(30) NOT NULL,

CONSTRAINT Emp_Gender_CK CHECK (Emp_Gender in ('M','F')),
CONSTRAINT Emp_Email_CK CHECK ( Emp_Email like '%_#__%._%')
);
It works this way, but what I want is this:
CREATE TABLE Employee (

CONSTRAINT Hire_Date_CK CHECK (Hire_Date <= curdate()),
CONSTRAINT Emp_Gender_CK CHECK (Emp_Gender in ('M','F')),
CONSTRAINT Emp_Email_CK CHECK ( Emp_Email like '%_#__%._%')
);
I don't know why sysdate function or getdate doesn't work and I also don't know how to implement the Constraint about the Hire_Date (I cannot do it with <= relationship). As it is now I have to give up in implementing them even if I will lose points.
Any help will be much appreciated.
You'll need a trigger to enforce such a constraint. Here's an example:
SQL> create table test
2 (
3 employee_id varchar2 (10),
4 hire_date date
5 );
Table created.
SQL> create or replace trigger trg_hd_biu
2 before insert or update of hire_date
3 on test
4 for each row
5 begin
6 if :new.hire_date not between date '1900-01-01' and sysdate
7 then
8 raise_application_error (-20001, 'Hire date out of range');
9 end if;
10 end;
11 /
Trigger created.
SQL> insert into test values ('1', date '2018-01-15');
1 row created.
SQL> insert into test values ('2', date '2018-05-25');
insert into test values ('2', date '2018-05-25')
*
ERROR at line 1:
ORA-20001: Hire date out of range
ORA-06512: at "SCOTT.TRG_HD_BIU", line 4
ORA-04088: error during execution of trigger 'SCOTT.TRG_HD_BIU'

I have done it already using another approach (because our teacher doesn't want us to create triggers. We have to make use of constraints only) and it works. Thanks for help any way.

You are single quoting your INT values in the WHERE clause → '5' & '2'.
Also, try JOINs.
SELECT M.msg_id,
M.uid_fk,

U.lname,

FROM messages M
INNER JOIN users_friends F ON F.friendID = M.uid_fk
