这是查询

我会适当地建立一个包含字段 ad_org_id、ad_client_id、cs_worker_cont_id 的索引。假设那是他们在熵中的顺序。

一般规则是为您必须执行频繁搜索或排序的所有列创建索引。在您的情况下，这是：

t.cs_work_code_id 
w.cs_work_code_id 
w.ad_checkroll_rates_id 
r.ad_checkroll_rates_id 
iscontract
t.isactive
w.isactive
r.isactive
t.cs_worker_cont_id 
t.ad_client_id 
t.ad_org_id
t.transaction_date
