方法详细资料

getPageSQL

public String getPageSQL(String sql)

getPageSQLStatement

public String getPageSQLStatement(String sql,
                                  long offset,
                                  long pageSize)

把正常sql转换成分页sql, 参数是 ?

 正常sql: select * from tb_bee

 假设 offset = 2
 假设 pageSize  = 9
 (mysql示例) 出来的sql:

sql - 正常查询sql

offset - offset

pageSize - pageSize

返回:

分页sql

initPagePara

                         long start,
                         long size)

getIdType

public int getIdType(Class c,
                     String idProperty)

指定者:

getIdType 在接口中 DBStyle
