The syntax differences between MySQL and SQL Server are mainly reflected in database objects, data types, SQL statements and other aspects. Database object differences include the storage engine and how filegroups are specified, and the creation of indexes and constraints. Data type differences involve differences in numeric types, character types, and date and time types. SQL statement differences are reflected in result set limitations, data insertion, update and delete operations, etc. Other differences include how identity columns, views, and stored procedures are created. Understanding these differences is important to avoid errors when using different database systems.
