• SET ANSI NULLS OFF
• Ability to insert null values into timestamp columns
• TEXT, NTEXT and IMAGE datatypes 
• CREATE TABLE, ALTER TABLE or CREATE INDEX syntax without parenthesis around the option
• Lot of options of procedure sp_configure 
• Specifying the SQLOLEDB provider for linked servers
• USER_ID function 
• Specifying NOLOCK or READUNCOMMITTED in the FROM clause of an UPDATE or DELETE statement.
• Specifying table hints without using the WITH keyword.
• Three-part and four-part column references.
• A string enclosed in quotation marks used as a column alias for an expression in a SELECT list:
