# SQLOR
SQLOR is a database api for python3, it is base on the python's DBAPI2
## Features
* Multiple database supported(Oracle, MySql, Postgresql, SQL Server
* Both asynchronous API & synchronous API supported
* Connection pools
* Connection life cycle managements
* Easy using API
* Resources(connection object, cursor object) automatic recycled
## requirements
* python 3.5 or above
* asyncio
* Oracle DBAPI2 driver(cx_Oracle)
* MySQL DBAPI2 driver(mysql-connector)
* Postgresql DBAPI2 driver(psycopg2-binrary)
* Asynchronous MySQL driver(aiomysql)
* Asynchronous Postgresql driver(aiopg)
* Other driver can be easy integreated
## Using
```
import asyncio
from sqlor.dbpools import DBPools
dbs={
"aiocfae":{
"driver":"aiomysql",
"async_mode":True,
"coding":"utf8",
"dbname":"cfae",
"kwargs":{
"user":"test",
"db":"cfae",
"password":"test123",
"host":"localhost"
}
},
"stock":{
"driver":"aiopg",
"async_mode":True,
"codeing":"utf-8",
"dbname":"stock",
"kwargs":{
"dbname":"stock",
"user":"test",
"password":"test123",
"host":"127.0.0.1"
}
},
"cfae":{
"driver":"mysql.connector",
"coding":"utf8",
"dbname":"cfae",
"kwargs":{
"user":"test",
"db":"cfae",
"password":"test123",
"host":"localhost"
}
}
}
loop = asyncio.get_event_loop()
pool = DBPools(dbs,loop=loop)
async def testfunc():
@pool.runSQL
def sql(db,ns,callback):
return {
"sql_string":"select * from product",
}
x = await sql('cfae',{},print)
x = await sql('aiocfae',{},print)
loop.run_until_complete(testfunc())
```
## API
### Databases description data(dbdesc)
sqlor uses a dbdesc data(databases description data) which description
how many databases and what database will using, and them connection parameters to create a dbpools objects
dbdesc data is a dict data, format of the dbdesc as follow:
```
{
"aiocfae":{ # name to identify a database connect
"driver":"aiomysql", # database dbapi2 driver package name
"async_mode":True, # indicte this connection is asynchronous mode
"coding":"utf8", # charset coding
"dbname":"cfae", # database real name
"kwargs":{ # connection parameters
"user":"test",
"db":"cfae",
"password":"test123",
"host":"localhost"
}
},
"cfae":{
"driver":"mysql.connector",
"coding":"utf8",
"dbname":"cfae",
"kwargs":{
"user":"test",
"db":"cfae",
"password":"test123",
"host":"localhost"
}
}
}
```
sqlor can using multiple databases and difference databases by using difference database driver
