一、实现功能
将需要执行sql语句写入脚本，然后，使用psql.py执行。
二、步骤
1.脚本内容
（1）us_population.sql
CREATE TABLE IF NOT EXISTS us_population (
"state" CHAR(2) NOT NULL,
"city" VARCHAR(18) NOT NULL,
"info"."population" BIGINT,
CONSTRAINT my_pk PRIMARY KEY ("state", "city")
);（2）us_population_queries.sql
SELECT "state" as "State",count("city") as "City Count",sum("population") as "Population Sum" FROM us_population GROUP BY "state" ORDER BY sum("population") DESC;2.执行脚本
（1）创建表
bin/psql.py localhost /opt/datas/phoenix_sql/us_population.sql（2）phoenix中向表中插入数据
upsert into "US_POPULATION"("state","city","population") values('NY','New York',8143197);
upsert into "US_POPULATION"("state","city","population") values('CA','Los Angeles',3844829);
upsert into "US_POPULATION"("state","city","population") values('IL','Chicago',2842518);
upsert into "US_POPULATION"("state","city","population") values('TX','Houston',2016582);
upsert into "US_POPULATION"("state","city","info"."population") values('PA','Philadelphia',1463281);
upsert into "US_POPULATION"("state","city","info"."population") values('AZ','Phoenix',1461575);
upsert into "US_POPULATION"("state","city","info"."population") values('TX','San Antonio',1256509);
upsert into "US_POPULATION"("state","city","info"."population") values('CA','San Diego',1255540);
upsert into "US_POPULATION"("state","city","info"."population") values('TX','Dallas',1213825);
upsert into "US_POPULATION"("state","city","info"."population") values('CA','San Jose',912332);（3）查询表
bin/psql.py localhost /opt/datas/us_population_queries.sql结果：
