三、数据库语句（MySQL）

一、生成数据库sql语句

from prestool.PresMySql import SqlStr

sql = SqlStr()

查询语句

target不传时，为全部字段，即*，where={'key':'value'}

sql.select_sql_str(table='table1', where={'id': 1, 'name': '张三'})

select * from table1 where id = 1 and name = '张三';

target=[i1,i2,i3]时，为相应字段

sql.select_sql_str(table='table1', target=['a', 'b', 'c'], where={'id': 1, 'name': '张三'})

select a, b, c from table1 where 1=1 and id=1 and name='张三';

limit=10 limit='10,1000' 为筛选限制字段

sql.select_sql_str(table='table1', target=['a', 'b', 'c'], order={'age': 'desc', 'score': 'desc'}, limit=20)

select a, b, c from table1 where 1=1 order by age desc, score desc limit 20;

where条件中有的字段为null或者not null时

sql.select_sql_str(table='table1', target=['a', 'b', 'c'], where={'id': 1},is_not_null={'age': True, 'name': None})
select a, b, c from table1 where 1=1 and id=1 and age is not null and name is null;

支持排序语句

sql.select_sql_str(table='table1', target=['a', 'b', 'c'], order={'age': 'desc', 'score': 'desc'})

select a, b, c from table1 order by age desc, score desc;

支持查询 in语句

sql.select_sql_str(table='table1', target=['a', 'b', 'c'], select_in={'orders': [123121312, 123123445, 213123]})

select a, b, c from table1 where 1=1 and orders in (123121312, 123123445, 213123);

支持like语句

sql.select_sql_str(table='table1', target=['a', 'b', 'c'], like={'name': '%光', 'address': "中国%"})

select a, b, c from table1 where 1=1 and name like '%光' and address like '中国%';

支持between语句

sql.select_sql_str(table='table1', target=['a', 'b', 'c'], between={'age': (10, 20), 'year': (2021, 2022)})

select a, b, c from table1 where 1=1 and age between 10 and 20 and year between 2021 and 2022;

支持大于、小于语句

sql.select_sql_str(table='table1', target=['a', 'b', 'c'],
                       compare={'age': {'>': 10, '<': 20}, 'year': {'>=': '2021'}})
                       
select a, b, c from table1 where 1=1 and age > 10 and age < 20 and year >= 2021;

更新语句

target为要更新的数据，为字典结构(支持大于、小于语句、between语句、like语句、in语句)

sql.update_sql_str(table='table1', target={'name': '李四', 'age': 15}, where={'id': 1, 'name': '张三'}) 

update table1
set name='李四',
    age=15
where id = 1
  and name = '张三';

删除数据

支持大于、小于语句、between语句、like语句、in语句

sql.delete_sql_str(table='table1', where={'id': 1, 'name': '张三'})

delete
from table1
where id = 1
  and name = '张三';

插入数据

sql.insert_sql_str(table='table1', target={'id': 1, 'name': '张三'})

insert into table1 (id, name)
values (1, '张三');

二、执行数据库语句

from prestool.PresMySql import PresMySql

pres = PresMySql()

初始化数据库信息

pres.mysql_host = ''
pres.mysql_port = 3306
pres.mysql_user = ''
pres.mysql_pwd = ''
pres.mysql_db_name = ''
pres.mysql_charset = 'utf8mb4'

执行相应语句即可，执行的方法参数等同于第三节所述的sql语句，如

pres.to_query(table='table1', target=['a', 'b', 'c'], between={'age': (10, 20), 'year': (2021, 2022)})

pres.to_insert(table='table1', target={'id': 1, 'name': '张三'})

pres.to_delete(table='table1', where={'id': 1, 'name': '张三'})

pres.to_update(table='table1', target={'name': '李四', 'age': 15}, where={'id': 1, 'name': '张三'})
