Alter Table Add Column Syntax Ask Question

I'm trying to programmatically add an identity column to a table Employees. Not sure what I'm doing wrong with my syntax.

ALTER TABLE Employees
  ADD COLUMN EmployeeID int NOT NULL IDENTITY (1, 1)

ALTER TABLE Employees ADD CONSTRAINT
    PK_Employees PRIMARY KEY CLUSTERED 
    (
      EmployeeID
    ) WITH( STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, 
    ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]

What am I doing wrong? I tried to export the script, but SQL Mgmt Studio does a whole Temp Table rename thing.

UPDATE: I think it is choking on the first statement with "Incorrect syntax near the keyword 'COLUMN'."

Just remove COLUMN from ADD COLUMN

ALTER TABLE Employees
  ADD EmployeeID numeric NOT NULL IDENTITY (1, 1)

ALTER TABLE Employees ADD CONSTRAINT
        PK_Employees PRIMARY KEY CLUSTERED 
        (
          EmployeeID
        ) WITH( STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, 
        ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
