syntax structure: 1. Cast Syntax structure: CAST (expression as data_type [(length)]) 2. Convert Syntax structure: CONVERT (data_type [(length)], expression [, style]) 3. Parse Syntax structure: PARSE (string_value as data_type [USING culture]) Where Parse is a new feature of SQL Server expression must be a string form of the converted Type Performance Analysis: Summarize: 1. The difference between
