 1、首先创建表结构：
 CREATE TABLE a_biz_situ_tab(
      "org_id" character varying(15),
     "row_id" character varying(15),
     "frequency_code" character varying(15),
     "currency_code" character varying(15),
     "acct_id" character varying(15),
     "acct_name" character varying(1000),
     "begin_balance_dr" numeric,
     "begin_balance_cr" numeric,
     "period_net_dr" numeric,
     "period_net_cr" numeric,
     "end_balance_dr" numeric,
     "end_balance_cr" numeric,
     "acct_id1" character varying(15),
     "increase_dr" numeric,
     "increase_cr" numeric,
     "rpt_dt" character varying(10)
 );
 2、导入insert语句
 ./cockroach sql --certs-dir=certs  --host=localhost --database=zybdb < a_biz_situ_tab.sql3、创建索引
 root@localhost:26257/zybdb> create index idx_org_id_rpt_dt on a_biz_situ_tab(org_id,rpt_dt);
 CREATE INDEXTime: 619.260155ms
root@localhost:26257/zybdb> show index from a_biz_situ_tab;
 +----------------+-------------------+--------+-----+--------+-----------+---------+----------+
 |     Table      |       Name        | Unique | Seq | Column | Direction | Storing | Implicit |
 +----------------+-------------------+--------+-----+--------+-----------+---------+----------+
 | a_biz_situ_tab | primary           |  true  |   1 | rowid  | ASC       |  false  |  false   |
 | a_biz_situ_tab | idx_org_id_rpt_dt | false  |   1 | org_id | ASC       |  false  |  false   |
 | a_biz_situ_tab | idx_org_id_rpt_dt | false  |   2 | rpt_dt | ASC       |  false  |  false   |
 | a_biz_situ_tab | idx_org_id_rpt_dt | false  |   3 | rowid  | ASC       |  false  |   true   |
 +----------------+-------------------+--------+-----+--------+-----------+---------+----------+
 (4 rows)Time: 2.529234ms
root@localhost:26257/zybdb> drop index idx_org_id_rpt_dt;
 DROP INDEXTime: 545.150951ms
4、业务状况表执行计划
 创建索引前：
 root@localhost:26257/zybdb> explain select
                          ->         row_id,
                          ->         acct_id,
                          ->         acct_name,
                          ->         begin_balance_dr,
                          ->         begin_balance_cr,
                          ->         period_net_dr,
                          ->         period_net_cr,
                          ->         end_balance_dr,
                          ->         end_balance_cr,
                          ->         acct_id1,
                          ->         increase_dr,
                          ->         increase_cr
                          ->     from
                          ->         a_biz_situ_tab
                          ->     where
                          ->         org_id =  '000000'
                          ->         and FREQUENCY_CODE=   'MON'
                          ->         and currency_code= 'CNY'
                          ->         and rpt_dt = replace( '20180701','-','')
                          ->     order by
                          ->         row_id,acct_id;
 +----------------+-------+------------------------+
