root@localhost:26257/zybdb> #往数据库导数：
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;
+----------------+-------+------------------------+
| Tree | Field | Description |
+----------------+-------+------------------------+
| sort | | |
| │ | order | +row_id,+acct_id |
| └── render | | |
| └── scan | | |
| | table | a_biz_situ_tab@primary |
| | spans | ALL |
+----------------+-------+------------------------+
(6 rows)Time: 34.108194ms
创建索引后：
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;
+----------------------+-------+-----------------------------------------------------+
| Tree | Field | Description |
+----------------------+-------+-----------------------------------------------------+
| sort | | |
| │ | order | +row_id,+acct_id |
| └── render | | |
| └── index-join | | |
| ├── scan | | |
| │ | table | a_biz_situ_tab@idx_org_id_rpt_dt |
| │ | spans | /"000000"/"20180701"-/"000000"/"20180701"/PrefixEnd |
| └── scan | | |
| | table | a_biz_situ_tab@primary |
+----------------------+-------+-----------------------------------------------------+
