pip install DBUtils --upgrade
快速开始
from easemysql import EaseMySQL
# 配置数据库连接
config = dict(host='localhost', user='username', password='password', database='dbname')
db = EaseMySQL(**config)
# 查询单条记录
result = db.one('table_name', dict(id=1))
# 查询多条记录
results = db.all('table_name', 'status = ?', [1])
# 使用条件列表进行复杂查询
results = db.all('table_name', [
'or',
['in', 'id', [1, 3, 4]],
['and', ['>', 'id', 5], 'id < 8', dict(id=[6, 7])],
dict(id=8),
dict(id=[9]),
])
# 插入记录
db.insert('table_name', dict(name='test', value=123))
# 更新记录
db.update('table_name', dict(value=456), 'id = 1')
# 删除记录
db.delete('table_name', 'id = 1')
