MS Access Create Table with Autoincrement and default date - sql

I try to create MS Access Table with autoincrement ID and Default Date field, but next query always says "Syntax error in CREATE TABLE statement.":
CREATE TABLE Table1
(
[ID] AUTOINCREMENT,
[Email] TEXT(255),
[ProductID] NUMBER,
[DateCreate] DATETIME,
[DateSend] DATETIME
);
ALTER TABLE Table1
ALTER [DateSend] DATETIME DEFAULT NOW() NOT NULL;
Who can help me to fix that query. Thanks!


There are many NUMBER types in Ms-Access, so you have to be specific. I guess you want Integer.
CREATE TABLE Table1
(
[ID] AUTOINCREMENT,
[Email] TEXT(255),
[ProductID] INTEGER,
[DateCreate] DATETIME,
[DateSend] DATETIME
);
The ALTER TABLE syntax requires ALTER COLUMN :
ALTER TABLE Table1
ALTER COLUMN
[DateSend] DATETIME DEFAULT NOW() NOT NULL;
You could also have those two in one statement:
CREATE TABLE Table1
(
[ID] AUTOINCREMENT,
[Email] TEXT(255),
[ProductID] INTEGER,
[DateCreate] DATETIME,
[DateSend] DATETIME DEFAULT NOW() NOT NULL
);
It's best practise to have a PRIMARY KEY on every table, and you probably intended that for the ID:
[ID] AUTOINCREMENT PRIMARY KEY,

CREATE TABLE Tblcontact
(
contactid AUTOINCREMENT PRIMARY KEY ,
firstname CHAR (60),
lastname CHAR (60),
email VARCHAR (75)
);

Cannot insert the value NULL into column 'Id' although Id is set

I have a strange problem.
I want to insert an item to a table from database. I use Entity Framework.
Although the Id is set, I keep getting the following error:
Cannot insert the value NULL into column 'Id', table 'project_atp.dbo.ShoppingCarts'; column does not allow nulls. INSERT fails.\r\nThe statement has been terminated."}
The table definition:
CREATE TABLE [dbo].[ShoppingCarts] (
[Id] INT NOT NULL,
[Guid] UNIQUEIDENTIFIER NULL,
[Name] NVARCHAR (255) NULL,
[Code] NVARCHAR (255) NULL,
[SupplierNo] NVARCHAR (255) NULL,
[SupplierName] NVARCHAR (255) NULL,
[Price] NVARCHAR (50) NULL,
[Quantity] INT NULL,
CONSTRAINT [PK_ShoppingCarts] PRIMARY KEY CLUSTERED ([Id] ASC)
);
Can you please advise what could be wrong here! Thanks!

By default Entity Framework assumes that an integer primary key is database generated. As the result Entity Framework would not include Primary Key field in the actual INSERT statement.
I would try to either play along and ALTER the table to auto-generate the ID (which judging by your comment you did)
or set StoreGeneratedPattern property of OnlineCarStore.Models.ShoppingCarts Id column to 'None'
or use annotation: [DatabaseGenerated(DatabaseGeneratedOption.None)].

Create table with UNIQUEIDENTIFIER as PK

I have been trying (unsuccessfully) to create a table with a UNIQUEIDENTIFIER as the primary key. The script below will create the table just fine, however there is no PK specified. This is my first time using a UNIQUEIDENTIFIER, however. Any ideas?
T-SQL
CREATE TABLE [dbo].[AgentRelationshipCodes]
(
Id UNIQUEIDENTIFIER NOT NULL DEFAULT NEWID(),
RelationshipId char(3) NULL,
EffectiveDate datetime NULL,
LastChangeDate datetime NOT NULL,
LastChangeId char(6) NOT NULL,
AgtTableId int FOREIGN KEY REFERENCES AgentTransmission(ID)
);
Management Studio

create table [dbo].[AgentRelationshipCodes]
(
Id UNIQUEIDENTIFIER NOT NULL PRIMARY KEY DEFAULT NEWID(),
.
.
.
)
Repeat for the other tables.

Syntax error on CREATE TABLE with INHERITS

So I'm new to Postgres and am trying to create a table that uses an INHERITS clause.
Can't figure out why I'm getting a syntax error (postgres 9.1):
CREATE TABLE images (
id SERIAL,
description VARCHAR NOT NULL,
filename VARCHAR NOT NULL,
created TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP,
modified TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP,
deleted TIMESTAMP DEFAULT NULL,
PRIMARY KEY(id)
);
CREATE TABLE posts (
id SERIAL,
title VARCHAR(50),
body_text VARCHAR,
image_id INTEGER,
created TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP,
modified TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP,
deleted TIMESTAMP DEFAULT NULL,
PRIMARY KEY(id),
FOREIGN KEY(image_id) REFERENCES images(id)
);
CREATE TABLE events (
date_time DATETIME NOT NULL,
venue VARCHAR(50) NOT NULL,
booking_details VARCHAR NOT NULL,
) INHERITS (posts);
Error
psql:2.sql:30: ERROR: syntax error at or near ")"
LINE 6: ) INHERITS (posts);
^

booking_details VARCHAR NOT NULL,
Remove the comma

Making one of my columns default the DateCreated to current time

I have the following SQL definition:
CREATE TABLE [dbo].[James] (
[JamesID] INT IDENTITY (1, 1) NOT NULL,
[Name] NVARCHAR (255) NOT NULL,
[DateCreated] DATETIME NULL,
CONSTRAINT [PK_dbo.James] PRIMARY KEY CLUSTERED ([JamesID] ASC)
);
How might I make it so new entries have the DateCreated filled out automatically when I create new entries.
What about existing data that has not had that column filled out?

If you are starting from scratch and assuming this is SQL Server:
CREATE TABLE [dbo].[James] (
[JamesID] INT IDENTITY (1, 1) NOT NULL,
[Name] NVARCHAR (255) NOT NULL,
[DateCreated] DATETIME NOT NULL DEFAULT CURRENT_TIMESTAMP,
CONSTRAINT [PK_dbo.James] PRIMARY KEY CLUSTERED ([JamesID] ASC)
);
If you want to update the table you can use this:
ALTER TABLE dbo.James
ADD CONSTRAINT DF_namehere DEFAULT CURRENT_TIMESTAMP FOR DateCreated;
However, any current NULL values will remain NULL with the ALTER TABLE solution. How you want to address this depends if you want to backfill information.

How i can change and run sql file into mssql

I have my database in sqlite .I exported sql file from sqlite manager. Now on executing that file into Microsoft SQL Server 2012 it is giving error on following lines.
DROP TABLE
IF EXISTS "Admin";
CREATE TABLE "AdvancePayments" (
"Id" INT PRIMARY KEY AUTOINCREMENT NOT NULL UNIQUE,
"date" VARCHAR,
"Name" VARCHAR,
"Amount" INT,
"Remarks" VARCHAR);
INSERT INTO "AdvancePayments"
VALUES (
1,
'11/22/2013',
'wqqw',
21,
'fgdsr');
CREATE TABLE "DVouchers" (
"DVid" INT PRIMARY KEY NOT NULL,
"vdate" VARCHAR DEFAULT(NULL),
"Vehiclenum" VARCHAR,
"Coupen" BOOL,
"Saleperson" VARCHAR,
"DVnumber" INT,
"Ares" VARCHAR,
"Ctitle" VARCHAR,
"remarks" VARCHAR,
"mEntry" BOOL,
"Cust_Id" INT,
FOREIGN KEY (Cust_Id) REFERENCES Customer_New(Cust_Id));
What is correct syntax for mssql?

You should write it as:
--DROP TABLE IF EXISTS Admin;
--query to drop a table
IF EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N'[dbo].[TableName]') AND type in (N'U'))
DROP TABLE [dbo].[TableName]
GO
CREATE TABLE [AdvancePayments]
(
[Id] INT IDENTITY(1,1) PRIMARY KEY NOT NULL ,--The MS SQL Server uses the IDENTITY keyword to perform an auto-increment feature
[date] VARCHAR(10),-- best practice is to use datetime datatype to store date feilds.
[Name] VARCHAR(100),
[Amount] INT,
[Remarks] VARCHAR(1000)
);
INSERT INTO AdvancePayments
VALUES (
--1,-- you cannot give an explicit value to identity column untill IDENTITY_INSERT is ON. So comment this.
'11/22/2013',
'wqqw',
21,
'fgdsr');
CREATE TABLE [DVouchers] (
[DVid] INT PRIMARY KEY NOT NULL,
[vdate] VARCHAR(20) DEFAULT(NULL),
[Vehiclenum] VARCHAR(100),
[Coupen] BIT,-- Bit is the datatype used for Boolean values.
[Saleperson] VARCHAR(100),
[DVnumber] INT,
[Ares] VARCHAR(100),
[Ctitle] VARCHAR(100),
[remarks] VARCHAR(100),
[mEntry] BIT,
[Cust_Id] INT,
FOREIGN KEY (Cust_Id) REFERENCES Customer_New(Cust_Id)
);
Note: In MS SQL default length of varchar datatype is 1. so you will have to specify length to each
varchar variable.

TSQL:
IF NOT OBJECT_ID('dbo.TableToDrop') IS NULL
BEGIN
DROP TABLE dbo.TableToDrop
END;
// change dbo. to your schema if necessary
