Getting Started with 3ds Max Plugin Configuration After installing Redshift you shouldn't have to do anything inside of 3ds Max to start using it but you can check to make sure the Redshift plug-in is loaded by going to the Plug-in Manager via the Customize menu. AUTO INCREMENT Field. Auto-increment allows a unique number to be generated automatically when a new record is inserted into a table. Often this is the primary key field that we would like to be created automatically every time a new record is inserted. As SQL Server DBAs we may need to generate a script for the creation of all Primary Keys, Unique and Foreign Key constraints. We know with the SQL Server native tools that there is not a way to meet this need all at the same time. In this tip we look at t.
AUTO INCREMENT Field

Syntax for MySQL
The following SQL statement defines the 'Personid' column to be an auto-increment primary key field in the 'Persons' table:
CREATE TABLE Persons (
Personid int NOT NULL AUTO_INCREMENT, LastName varchar(255) NOT NULL, FirstName varchar(255), Age int, PRIMARY KEY (Personid) );
MySQL uses the AUTO_INCREMENT keyword to perform an auto-increment feature.
By default, the starting value for AUTO_INCREMENT is 1, and it will increment by 1 for each new record.
To let the AUTO_INCREMENT sequence start with another value, use the following SQL statement:
To insert a new record into the 'Persons' table, we will NOT have to specify a value for the 'Personid' column (a unique value will be added automatically):
INSERT INTO Persons (FirstName,LastName)
VALUES ('Lars','Monsen');
The SQL statement above would insert a new record into the 'Persons' table. The 'Personid' column would be assigned a unique value. The 'FirstName' column would be set to 'Lars' and the 'LastName' column would be set to 'Monsen'.
Syntax for SQL Server
The following SQL statement defines the 'Personid' column to be an auto-increment primary key field in the 'Persons' table:
CREATE TABLE Persons (
Personid int IDENTITY(1,1) PRIMARY KEY, LastName varchar(255) NOT NULL, FirstName varchar(255), Age int );
The MS SQL Server uses the IDENTITY keyword to perform an auto-increment feature.
In the example above, the starting value for IDENTITY is 1, and it will increment by 1 for each new record.
Download unix terminal for mac. Tip: To specify that the 'Personid' column should start at value 10 and increment by 5, change it to IDENTITY(10,5).
To insert a new record into the 'Persons' table, we will NOT have to specify a value for the 'Personid' column (a unique value will be added automatically):
INSERT INTO Persons (FirstName,LastName)
VALUES ('Lars','Monsen');
The SQL statement above would insert a new record into the 'Persons' table. The 'Personid' column would be assigned a unique value. The 'FirstName' column would be set to 'Lars' and the 'LastName' column would be set to 'Monsen'.
Syntax for Access
The following SQL statement defines the 'Personid' column to be an auto-increment primary key field in the 'Persons' table:
CREATE TABLE Persons (
Personid AUTOINCREMENT PRIMARY KEY, LastName varchar(255) NOT NULL, FirstName varchar(255), Age int );
The MS Access uses the AUTOINCREMENT keyword to perform an auto-increment feature.
By default, the starting value for AUTOINCREMENT is 1, and it will increment by 1 for each new record.
Tip: To specify that the 'Personid' column should start at value 10 and increment by 5, change the autoincrement to AUTOINCREMENT(10,5).

Virtual dj 8 old version free download. The SQL statement above would insert a new record into the 'Persons' table. The 'Personid' column would be assigned a unique value. The 'FirstName' column would be set to 'Lars' and the 'LastName' column would be set to 'Monsen'.
Syntax for OracleGenerating Primary Keys For Redshift Definition
In Oracle the code is a little bit more tricky.
You will have to create an auto-increment field with the sequence object (this object generates a number sequence).
Use the following CREATE SEQUENCE syntax:
CREATE SEQUENCE seq_person
MINVALUE 1 START WITH 1 INCREMENT BY 1 CACHE 10;
The code above creates a sequence object called seq_person, that starts with 1 and will increment by 1. It will also cache up to 10 values for performance. The cache option specifies how many sequence values will be stored in memory for faster access.
To insert a new record into the 'Persons' table, we will have to use the nextval function (this function retrieves the next value from seq_person sequence):
INSERT INTO Persons (Personid,FirstName,LastName)
VALUES (seq_person.nextval,'Lars','Monsen');
The SQL statement above would insert a new record into the 'Persons' table. The 'Personid' column would be assigned the next number from the seq_person sequence. The 'FirstName' column would be set to 'Lars' and the 'LastName' column would be set to 'Monsen'.
