功能列表

特征	DBR	松鼠	sqrl	戈克
SelectBuilder	+	+	+	+
插入式构造器	+	+	+	+
UpdateBuilder	+	+	+	+
DeleteBuilder	+	+	+	+
PostgreSQL支持		+	+	+
定制占位符		+	+	+
加入支持		+	+	+
查询构建器中的子查询		+	+	+
列的别名		+	+	+
案例表达		+	+	+

这里的一些解释：

Custom placeholders - 不仅可以使用吗?占位符，对PostgreSQL有用
JOINs support - 能够构建连接的能力，例如Select("*").From("a").Join("b")
Subquery in query builder - 当您用一个构建器准备一个子查询时，然后将其传递给另一个构建器。像：

 subQ := Select ( "aa" , "bb" ). From ( "dd" )
qb := Select (). Column ( subQ ). From ( "a" )

Aliases for columns - 轻松使用列的方式，尤其是在列指定列的情况下：

 subQ := Select ( "aa" , "bb" ). From ( "dd" )
qb := Select (). Column ( Alias ( subQ , "alias" )). From ( "a" )

CASE expression - 案例表达的句法糖
