类 IDbQueryBuilder

IDbQuery

net.jkcode.jkmvc.query.IDbQueryBuilder

所有已实现的接口:

IDbQueryBuilderAction, IDbQueryBuilderDecoration, IDbQueryBuilderQuoter

直接已知子类:

DbQueryBuilderQuoter

public class IDbQueryBuilder
extends IDbQuery
implements IDbQueryBuilderQuoter, IDbQueryBuilderAction, IDbQueryBuilderDecoration

sql构建器 1 作用 依次继承 DbQueryBuilderAction 处理动作子句 + DbQueryBuilderDecoration 处理修饰子句 提供select/where等类sql的方法, 但是调用方法时, 不直接拼接sql, 而是在compile()时才延迟拼接sql, 因为调用方法时元素可以无序, 但生成sql时元素必须有序

2 CharSequence接口 为了适配 DbQueryBuilder 中的查询方法的查询参数类型, 如 select() / where() 否则要重载很多方法来接收 DbExpr 参数
