# Pydbclib

Pydbclib is Python Database Connectivity Lib, a general database operation toolkit for **Python 3.6+**

## Installation:

```shell script

pip3 install pydbclib

```

## Example:

```python

from pydbclib import connect

# 使用with上下文，可以自动提交，自动关闭连接

with connect("sqlite:///:memory:") as db:

    db.execute('create table foo(a integer, b varchar(20))')

    # 统一使用':[name]'形式的SQL的占位符

    db.execute("insert into foo(a,b) values(:a,:b)", [{"a": 1, "b": "one"}]*4)

    print(db.read("select * from foo").get_one())

    print(db.read("select * from foo").get_all())

    print(db.read("select * from foo").to_df())

    

    # 对表常用操作的封装

    table = db.get_table("foo")

    table.insert([{"a": 2, "b": "two"}]*2)  # 插入两条记录

    table.find({"b": "two"}).get_all()  # 查出b='two'的所有记录

    table.update({"a": 2, "b": "two"}, {"b": "2"})  # 将a=2 and b='two'的所有记录的b字段值更新为'2'

    table.find({"a": 2}).get_all()  # 查出a=2的所有记录

    table.delete({"a": 2})  # 删除a=2的所有记录

```

#### 常用数据库连接示例  

Common Driver  

    # 使用普通数据库驱动连接，driver参数指定驱动包名称

    # 例如pymysql包driver='pymysql',connect函数其余的参数和driver参数指定的包的创建连接参数一致

    # 连接mysql

    db = pydbclib.connect(user="user", password="password", database="test", driver="pymysql")

    # 连接oracle

    db = pydbclib.connect('user/password@local:1521/xe', driver="cx_Oracle")

    # 通过odbc方式连接

    db = pydbclib.connect('DSN=mysqldb;UID=user;PWD=password', driver="pyodbc")  

    # 通过已有驱动连接方式连接

    import pymysql

    con = pymysql.connect(user="user", password="password", database="test")

    db = pydbclib.connect(driver=con)

Sqlalchemy Driver

    # 使用Sqlalchemy包来连接数据库，drvier参数默认为'sqlalchemy'

    # 连接oracle

    db = pydbclib.connect("oracle://user:password@local:1521/xe")

    # 连接mysql

    db = pydbclib.connect("mysql+pyodbc://:@mysqldb")

    # 通过已有engine连接

    from sqlalchemy import create_engine

    engine = create_engine("mysql+pymysql://user:password@localhost:3306/test")

    db = pydbclib.connect(driver=engine)
