I need to assign default value to column SERVERTIME with datatype TIMESTAMP_NTZ in snowflake.
I have a below query:-
CREATE TABLE STG_ORDER_DETAIL
(
ORDERID NUMBER(38,0) not null,
ORDER_TYPE VARCHAR(3),
AGGRID VARCHAR(20),
AGGRNAME VARCHAR(250),
MERCHANTID VARCHAR(20) not null,
SERVERTIME NOT NULL DEFAULT '1900-01-01'::TIMESTAMP_NTZ(9),
CURRENCY VARCHAR(5),
constraint STG_ORDER_DETAIL_PK primary key (ORDERID, MERCHANTID) not enforced);
getting syntax error.
Please make sure the data type is included and matched with the expression:
CREATE TABLE STG_ORDER_DETAIL
(
ORDERID NUMBER(38,0) not null,
ORDER_TYPE VARCHAR(3),
AGGRID VARCHAR(20),
AGGRNAME VARCHAR(250),
MERCHANTID VARCHAR(20) not null,
SERVERTIME TIMESTAMP_NTZ(9) NOT NULL DEFAULT '1900-01-01'::TIMESTAMP_NTZ(9),
CURRENCY VARCHAR(5),
constraint STG_ORDER_DETAIL_PK primary key (ORDERID, MERCHANTID) not enforced);

So I tried to insert data in the ''customer'' table but I always get this certain error (at the bottom).
Can anyone pinpoint if I miss anything or if it's lacking?
create table rooms
(
roomid int identity(1,1) primary key,
roomNo varchar(250) not null unique,
roomType varchar(250) not null,
bed varchar(250) not null,
price bigint not null,
booked varchar(50) default 'NO'
);
insert into rooms (roomNo, roomType, bed, price) values (010, 'Studio with AC', 'Single', '1000');
create table customer
(
cid int identity(1,1) primary key,
cname varchar(250) not null,
mobile bigint not null,
nationality varchar(250) not null,
gender varchar(50) not null,

idproof varchar(50) not null,
addres varchar(250) not null,
checkIn varchar(250) not null,
checkOut varchar(250),
chekOut varchar(250) not null default 'NO',
roomid int foreign key references rooms(roomid)
);
insert into customer (cname,mobile,nationality,gender,dob,idproof,addres,checkIn,customer.roomid) values ('Kayano Ai', 09238400394, 'Japanese', 'Female', '01-02-1998', '8923giaf', 'Somewhere', 'YES', 20);
the error notif I got is
The INSERT statement conflicted with the FOREIGN KEY constraint "FK__customer__roomid__1F98B2C1". The conflict occurred in database "myHotel", table "dbo.rooms", column 'roomid'.
When you enter row into your customer table, customer.roomid should exist in the rooms table first.
Fist make sure the room exists or insert a new room.
INSERT INTO rooms ( roomid,roomNo, ...) VALUES (1,'room1',...);
Then insert into customer with an custormer.roomid that exists in the room table (1 in the example)
INSERT INTO customer ( cid,cname,roomid ...) VALUES (15,'customer name',1,...);
The ArtistID column in Piece table refers to the ArtistID in the Artist table. Likewise, the LocationID column in Piece refers to LocationID in the GeographicLocation table. However, both foreign key references throw a "not the same data type as referencing column" error. What am I doing wrong?
CREATE TABLE dbo.Artist

LastName VARCHAR(50) NOT NULL,
FirstName VARCHAR(40) NOT NULL,
Nationality VARCHAR(10) NULL,
BirthYear SMALLINT NOT NULL CHECK(BirthYear <= 1980),

Sex CHAR(1) NOT NULL CHECK(Sex = 'F' OR Sex = 'M')

CREATE TABLE dbo.GeographicLocation

I think you missed a table here, which is AppraiserID column in Piece table refers to the AppraiserID in the Appraisertable
So, when I execute your SQL I am getting below error:
Foreign key 'FK__Piece__Appraiser__322C6448' references invalid table 'Appraiser'.
First Create a table called Appraiser, then create Foreign key references for those column.
Below SQL I am able to create all tables and Foreign key references:
CREATE TABLE dbo.Artist
(ArtistID SMALLINT PRIMARY KEY IDENTITY,
LastName VARCHAR(50) NOT NULL,
FirstName VARCHAR(40) NOT NULL,
Nationality VARCHAR(10) NULL,
BirthYear SMALLINT NOT NULL CHECK(BirthYear <= 1980),

CREATE TABLE dbo.GeographicLocation

I'm getting error saying:

CREATE TABLE Test (ID INT not null IDENTITY Primary key,

Try this syntax:
CREATE TABLE Test

CONSTRAINT Test_CreatedBy DEFAULT USER_NAME(),

CONSTRAINT Test_CreatedDate DEFAULT GETDATE(),

CONSTRAINT Test_LastUpdated DEFAULT GETDATE()
);
GO
dbfiddle here
Or if you prefer use ALTER TABLE:
CREATE TABLE Test
(
ID INT not null IDENTITY Primary key,
CreatedBy VARCHAR(20) not null,
CreatedDate DATETIME not null,
UpdatedBy VARCHAR(20) not null,
LastUpdated DATETIME not null
);
GO
ALTER TABLE Test
ADD CONSTRAINT Test_CreatedBy DEFAULT USER_NAME() FOR CreatedBy;
GO
ALTER TABLE Test
ADD CONSTRAINT Test_CreatedDate DEFAULT GETDATE() FOR CreatedDate;
GO
ALTER TABLE Test
ADD CONSTRAINT Test_UpdatedBy DEFAULT USER_NAME() FOR UpdatedBy;
GO
ALTER TABLE Test
ADD CONSTRAINT Test_LastUpdated DEFAULT GETDATE() FOR LastUpdated;
GO
dbfiddle here
You could define the constraint as column level as follow
CREATE TABLE Test (
ID INT NOT NULL IDENTITY(1,1) Primary key,
CreatedBy VARCHAR(20) NOT NULL DEFAULT USER_NAME(),
CreatedDate DATETIME NOT NULL DEFAULT GETDATE(),
UpdatedBy VARCHAR(20) NOT NULL DEFAULT USER_NAME(),
LastUpdated DATETIME NOT NULL DEFAULT GETDATE());

But I'm getting the following error:
Column 'registration.user_id' is not the same length or scale as referencing column 'passport.user_id' in foreign key 'fk_uid'. Columns participating in a foreign key relationship must be defined with the same length and scale.
How to rectify this problem?
cast or convert the user_id in registration to varchar(200) ie same as the one in passport
user_id as CONVERT(VARCHAR(200),
substring(apply_type,1,4) +
convert(char(45),id) )

why is that when i reference to "aircraft" it said invalid table??
what is wrong with my code??
You have to specify which field to reference:
foreign key (mod_code) references model (mod_code),
The foreign key constraint consists of 2 parts:
ALTER TABLE aircraft
ADD CONSTRAINT fk_aircraft_model
FOREIGN KEY (mod_code) -- here you specify the field(s) to reference from in the aircraft table
REFERENCES model (mod_code) -- here you specify the field(s) to reference to in the model table
You are creating the tables in the wrong order. charter references aircraft but create table aircraft doesn't appear until later.
