Syntax

Root documentation

• Create Table
• Alter table (second block)
• Function
• Table as select

Primary Key

Actually, you can't define a primary key in a create table or alter table column statement (for now 20180219, you can only define a default constraint). You still can define a primary key if you add a column.

• Add (ALTER TABLE column_definition (Transact-SQL))

ALTER TABLE dbo.DimAccount 
   add columnNamePK int 
   CONSTRAINT PK_DimAccount PRIMARY KEY NONCLUSTERED NOT ENFORCED;

• Delete

ALTER TABLE dbo.DimAccount drop constraint PK_DimAccount;
ALTER TABLE dbo.DimAccount drop column columnNamePK;
