 ## Security: SQL Injection
 SQLE uses the database/sql‘s argument placeholders to build parameterized SQL statement, which will automatically escape arguments to avoid SQL injection. eg if it is PostgreSQL, please apply [UsePostgres](use.go#L5) on SQLBuilder or change [DefaultSQLQuote](sqlbuilder.go?L16) and [DefaultSQLParameterize](sqlbuilder.go?L17) to update parameterization options.
