I am completely new in Postgres commands.
I have the following DB2 commands to create tables and table spaces:
CREATE USER TEMPORARY TABLESPACE MYSPACE MANAGED BY AUTOMATIC STORAGE#
CREATE TABLESPACE SYSTOOLSPACE MANAGED BY AUTOMATIC STORAGE#
CREATE SEQUENCE REVISION AS BIGINT START WITH 1 INCREMENT BY 1 MAXVALUE 4611686018427387903 CYCLE CACHE 1000#
Now i want to run these commands in postgresql , I have tried with
my_db=# CREATE USER TEMPORARY TABLESPACE MYSPACE MANAGED BY AUTOMATIC STORAGE;
ERROR: syntax error at or near "TABLESPACE"
LINE 1: CREATE USER TEMPORARY TABLESPACE MYSPACE MANAGED BY AUTO...
my_db=# CREATE TABLESPACE SYSTOOLSPACE MANAGED BY AUTOMATIC STORAGE;
ERROR: syntax error at or near "MANAGED"
LINE 1: CREATE TABLESPACE SYSTOOLSPACE MANAGED BY AUTOMATIC STORAGE;
I also have this DB2 CREATE TABLE statement:
CREATE TABLE USER (
ID BIGINT GENERATED BY DEFAULT AS IDENTITY (START WITH 1 INCREMENT BY 1 NO MAXVALUE NO CYCLE CACHE 100),
E_VER BIGINT NOT NULL,
NAME VARCHAR(38) NOT NULL UNIQUE,
EMAIL_ADDRESS VARCHAR(255) NOT NULL,
PASSWORD VARCHAR(32) NOT NULL,
SUPER_ADMIN SMALLINT NOT NULL,
MAIN_ADMIN SMALLINT NOT NULL,
SERVER_ADMIN SMALLINT NOT NULL,
GROUP_ADMIN SMALLINT NOT NULL,
CLIENT_ADMIN SMALLINT NOT NULL,
ENABLED SMALLINT NOT NULL,
HIDDEN SMALLINT NOT NULL,
PRIMARY KEY (ID)
)#
and I have tried to convert this to Postgres:
CREATE SEQUENCE USER_seq START WITH 1 INCREMENT BY 1;
CREATE TABLE USER (
ID BIGINT DEFAULT NEXTVAL ('USER_seq'),
E_VER BIGINT NOT NULL,
NAME VARCHAR(38) NOT NULL UNIQUE,
EMAIL_ADDRESS VARCHAR(255) NOT NULL,
PASSWORD VARCHAR(32) NOT NULL,
SUPER_ADMIN SMALLINT NOT NULL,
MAIN_ADMIN SMALLINT NOT NULL,
SERVER_ADMIN SMALLINT NOT NULL,
GROUP_ADMIN SMALLINT NOT NULL,
CLIENT_ADMIN SMALLINT NOT NULL,
ENABLED SMALLINT NOT NULL,
HIDDEN SMALLINT NOT NULL,
PRIMARY KEY (ID)
)#
by http://www.sqlines.com/online this online site. After running this command i am getting error like
my_db=# CREATE SEQUENCE USER_seq START WITH 1 INCREMENT BY 1;
CREATE SEQUENCE
my_db=#
my_db=#
my_db=# CREATE TABLE USER (
my_db(# ID BIGINT DEFAULT NEXTVAL ('USER_seq'),
my_db(# E_VER BIGINT NOT NULL,
my_db(# NAME VARCHAR(38) NOT NULL UNIQUE,
my_db(# EMAIL_ADDRESS VARCHAR(255) NOT NULL,
my_db(# PASSWORD VARCHAR(32) NOT NULL,
my_db(# SUPER_ADMIN SMALLINT NOT NULL,

my_db(# SERVER_ADMIN SMALLINT NOT NULL,
my_db(# GROUP_ADMIN SMALLINT NOT NULL,
my_db(# CLIENT_ADMIN SMALLINT NOT NULL,
my_db(# ENABLED SMALLINT NOT NULL,
my_db(# HIDDEN SMALLINT NOT NULL,
my_db(# PRIMARY KEY (ID)
my_db(# );
ERROR: syntax error at or near "USER"
LINE 1: CREATE TABLE USER (
^
Anything wrong this conversion? Any suggestion solve this error?
USER is a reserved word, you need to escape it as CREATE TABLE "USER".
As for your CREATE USER and CREATE TABLESPACE commands, that's just wrong syntax. There's no MANAGED BY in Postgres for example.

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(),
report varchar NOT NULL,
users varchar NOT NULL,
"hour" int4 NULL,
min int4 NULL,
daily_frequency int4 NULL,
daily_workday bool NULL,
weekly_frequency int4 NULL,
weekly_days varchar NULL,
monthly_sected_days varchar NULL,
last_updated timestamp NULL,
deleted bool NULL,
CONSTRAINT schedule_pkey PRIMARY KEY (id),
CONSTRAINT schedule_report_fkey FOREIGN KEY (report) REFERENCES pdb_interface.report("Id"),
CONSTRAINT schedule_users_fkey FOREIGN KEY (users) REFERENCES pdb_interface.users("Id"));
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
I have a table that is already created with data and I need only modify the schema to add some constraints .
my created tabled schema
CREATE TABLE public.note (
note_id bigint NOT NULL,
confidential boolean NOT NULL,
follow_up_date date,
notification_date date,
priority integer NOT NULL,
recurring_follow_up_interval interval,
status character varying(255) NOT NULL,
create_date timestamp with time zone,
deleted boolean NOT NULL,
last_modified_date timestamp with time zone,
time_spent integer,
title text,
version bigint NOT NULL,
assigned_to_id bigint,
note_category_id bigint NOT NULL,
created_by_id bigint,
last_modified_by_id bigint
);
what I need to match
create table note
(
note_id bigint default nextval('note_id_seq'::regclass) not null,
confidential boolean not null,
follow_up_date date,
notification_date date,
priority integer default 0 not null,
recurring_follow_up_interval interval,
status varchar(255) not null,
create_date timestamp with time zone,
deleted boolean default false not null,
last_modified_date timestamp with time zone,
time_spent integer,
title text,
version bigint default 0 not null,
assigned_to_id bigint,
note_category_id bigint not null,
created_by_id bigint,
last_modified_by_id bigint,
constraint note_pkey
primary key (note_id),
constraint fk_4nrhbn2j8j2vqqh78vleef9xr
foreign key (created_by_id) references admin_user,
constraint fk_eid7x7jfvjoe1h5tnyouhmqpa
foreign key (assigned_to_id) references admin_user,
constraint fk_oi5l4dg3sg5ep5neagmvp9r7o
foreign key (note_category_id) references note_category,
constraint fk_tk8ncyc0hmdi3gfh67b4jyu3l
foreign key (last_modified_by_id) references admin_user
);
as you can see it missing all defaults + all constraint to the other tables
any way to copy the intended schema to the created one without loosing the data
I am using Postgres 12
UPDATE
I know I could use alter to modify some columns but it will be a long process for me as there are many columns and I got more than 300 tables that have the same case
I manually alter one column to add sequence but I need easier way to do that for all columns
ALTER TABLE ONLY note ALTER COLUMN note_id SET DEFAULT nextval('note_id_seq'::regclass);
I'm stumped as to why I'm getting the following error
operator does not exist: character varying = text[]
when the following query is running in production:-
INSERT INTO message_status
(created_datetime,correlation_id,batch_id,entity_type,entity_id,entity_status,entity_message,effective_date)
VALUES
('2020-02-04 10:24:14.291000000','6dc16864-5820-475e-918e-51b15722c08a','34d9c646-9bc2-4389-9789-9c0482ba743e','Benchmark','ABCDEFGH','VALIDATION_ERRORED','{"type":"NO_RESULTS","properties":{}}','2020-01-12');
Not able to reproduce LOCALLY or in DBEAVER. Is there anything obviously wrong with this query? We recently migrated from AWS RDS MySQL to AWS Aurora Postgres
DDL
CREATE TABLE public.message_status (

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 am Migrating my database from MySQL to PostgreSQL.While creating table I got an error which I can't resolve.My MySQL Query is like this.
MYSQL Query
CREATE TABLE `configuration` (
`Name` varchar(300) NOT NULL,
`Value` varchar(300) default NULL,
`CType` char(1) default NULL,
`Size` int(11) default NULL,
`CGroup` varchar(50) default NULL,
`RestartReq` char(1) NOT NULL default 'Y',
`Display` char(1) NOT NULL default 'Y',
PRIMARY KEY (`Name`),
KEY `CType` (`CType`),
CONSTRAINT `configuration_ibfk_1` FOREIGN KEY (`CType`) REFERENCES `conftype` (`CType`)
)ENGINE=InnoDB DEFAULT CHARSET=latin1 COLLATE=latin1_bin`
PostgreSQL Query
CREATE TABLE configuration (
Name varchar(300) PRIMARY KEY,
Value varchar(300) default NULL,
CType char(1) default NULL,
Size integer default NULL,
CGroup varchar(50) default NULL,
RestartReq char(1) NOT NULL default 'Y',
Display char(1) NOT NULL default 'Y',
KEY CType (CType),
CONSTRAINT `configuration_ibfk_1` FOREIGN KEY (CType) REFERENCES conftype (CType)
)
Running File with
psql -h localhost -p 5432 -U postgres -f ps.sql testdb
Error getting
psql:ps.sql:40: ERROR: syntax error at or near "(" at character 287
psql:ps.sql:40: LINE 9: KEY CType ('CType'),
From the MySQL documentation:
KEY is normally a synonym for INDEX.
In PostgreSQL you have to create the index separately from the table:
CREATE TABLE configuration (
name varchar(300) PRIMARY KEY,
value varchar(300),
ctype char(1),
size integer,
cgroup varchar(50),
restartreq boolean NOT NULL DEFAULT true,
display boolean NOT NULL DEFAULT true,
CONSTRAINT configuration_ibfk_1 FOREIGN KEY (ctype) REFERENCES conftype (ctype)
);
CREATE INDEX conf_key ON configuration(ctype);
A few other points:
PostgreSQL identifiers (mainly table and column names) are case-insensitive except when double-quoted. The standard approach is to put identifiers in lower case and keywords in upper case.
Using a varchar(300) as a PRIMARY KEY is usually not a good idea for performance reasons. Consider adding a serial type.
The default value of a column is NULL when nothing is specified, so no need to specify DEFAULT NULL.
PostgreSQL has a boolean data type.
