Here is the SQL I'm using to create my table:
create table LAB_REQUESTS_REQUREMENTS
(
id INTEGER not null,
request_id INTEGER not null,
test_id INTEGER not null,
requrement VARCHAR2(30) not null,
assistant_id INTEGER,
measured_result VARCHAR2(50),
measured_condition VARCHAR2(50),
price_id INTEGER not null,
single_price NUMBER(15,2) default 0 not null,
measured_date DATE,
measure NVARCHAR2(30),
metric_tolerance NVARCHAR2(30)
)
tablespace VIK
pctfree 10
initrans 1
maxtrans 255
storage
(
initial 64K
next 1M
minextents 1
maxextents unlimited
);
How should I go about inserting those characters inside 'MEASURE' for example without going through conversion when inserting and then reading from the table?

I am currently trying to convert a postgres query to be compatible with Snowflake and work the same way.
Postgres
CREATE SEQUENCE IF NOT EXISTS public.etl_jobs_delta_loading_id_seq
START WITH 1
INCREMENT BY 1
NO MINVALUE
NO MAXVALUE
CACHE 1;
CREATE TABLE IF NOT EXISTS public.etl_jobs_delta_loading
(
id INTEGER DEFAULT nextval('public.etl_jobs_delta_loading_id_seq'::regclass) NOT NULL,
job_name VARCHAR(500) NOT NULL,
loaded_until TIMESTAMP,
etl_execution_time TIMESTAMP,
execution_status VARCHAR(30)
);
I translated the sequence to Snowflake, but keep getting errors while trying to get the nextVal in snowflake.
Snowflake
CREATE OR REPLACE SEQUENCE etl_jobs_delta_loading_id_seq
START = 1
INCREMENT = 1
CREATE TABLE IF NOT EXISTS public.etl_jobs_delta_loading
(
id INTEGER DEFAULT nextval('public.etl_jobs_delta_loading_id_seq'::regclass) NOT NULL, -- statement that needs to be converted
job_name VARCHAR(500) NOT NULL,
loaded_until TIMESTAMP,
etl_execution_time TIMESTAMP,
execution_status VARCHAR(30)
);
I have tried various approaches on creating the etl_jobs_delta_loading table but no luck till now. Any ideas on how to implement this in snowflake?
The correct syntax to get value from sequence is <seq_name>.NEXTVAL:
CREATE OR REPLACE SEQUENCE PUBLIC.etl_jobs_delta_loading_id_seq
START = 1
INCREMENT = 1;
CREATE TABLE IF NOT EXISTS public.etl_jobs_delta_loading
(
id INTEGER DEFAULT public.etl_jobs_delta_loading_id_seq.NEXTVAL NOT NULL,
job_name VARCHAR(500) NOT NULL,
loaded_until TIMESTAMP,
etl_execution_time TIMESTAMP,
execution_status VARCHAR(30)
);
Related: Sequences as Expressions
Alternatively using IDENTITY/AUTOINCREMENT property:
CREATE OR REPLACE TABLE public.etl_jobs_delta_loading
(
id INTEGER NOT NULL IDENTITY(1,1),
job_name VARCHAR(500) NOT NULL,
loaded_until TIMESTAMP,
etl_execution_time TIMESTAMP,
execution_status VARCHAR(30)
);
First of all can I give Varchar for primary key? Here is my create table;
CREATE TABLE appinfo (
app_id VARCHAR (30) PRIMARY KEY,
app_secret VARCHAR ( 500 ) NOT NULL,
app_name VARCHAR ( 255 ) NOT NULL,
app_type VARCHAR ( 255 ) NOT NULL,
prog_lang VARCHAR ( 255 ) NULL,
description VARCHAR ( 255 ) NULL,
created_on TIMESTAMP NOT NULL DEFAULT NOW()
);
And I am trying to insert below value
INSERT INTO appinfo (app_id, app_secret, app_name, app_type)
VALUES ('ABC1', 'aaaaaaabbbbbbccccccccc', 'AccountInfoAPI', 'API');
but this shows below error;
ERROR: invalid input syntax for type integer: "ABC1"
LINE 2: VALUES ('ABC1', 'aaaaaaabbbbbbccccccccc', 'AccountInfoAPI...
I am very new to Postgres and I am not sure where is this Integer coming from. Or is that because Primary key is always Integer in Postgres?
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 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(# );
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 have the following tables :
CREATE TABLE public.participant_audit

How can I fix this issue ??
The problem is in your trigger. Count the columns that you are trying to insert into the audit table here.
insert into participant_audit
(participant_audit_id, participant_id , shared_asset_id , asset_role_type , user_external_ref_uuid,
user_first_name , user_last_name , user_email_address , deleted_timestamp, row_updated_timestamp,
row_created_timestamp , row_created_by_db_user , row_updated_by_db_user , created_by_client,
updated_by_client
)
select NEW.* ;
That's quite a few more than what's contained in NEW because your insert statement has only 10 columns in it. I believe some of your columns maybe taking NULL values. Pass nulls explicitly in the SELECT part of your statement inside the trigger.
