Python writes sqlserver,oracle,mysql data queries and inserts data

SQL Server Method:

Insert Data Code Demo ( context Manager method ):

Import Pymssql,uuid
From class_area.class_readconf import readdate #导入读取配置文件模块方法
Sql_data=readdate (' sqlserver.conf ', ' DATABASE ', ' Config '). ReadData ()
Read_data=readdate (' area.conf ', ' areas ', ' Config '). ReadData ()
Area_read_2=eval (Read_data)
# Server database servers name or IP
# User Username
# password Password
# database name '
Class SQL Server ():
def insert_sql_server (self):
With Pymssql.connect (eval (sql_data) [' Server '],eval (sql_data) [' User '],eval (sql_data) [' Password '],eval (sql_data) [ ' Database ']) as Conn:
With Conn.cursor () as cursor:
For Data_row in range (len (area_read_2)):
area_code=area_read_2[data_row][' Code ']
area_name=area_read_2[data_row][' Name ']
Center_point= ",". Join ((area_read_2[data_row][' latitude '],area_read_2[data_row][' longitude '))
area_parentcode=area_read_2[data_row][' Parentcode ']
Sql= (' INSERT into T_sys_area (id,area_code,area_name,center_point,area_parentcode) VALUES (%s,%s,%s,%s,%s) '% (' \ ' + STR (UUID.UUID1 ()). Replace ('-', ') + ' \ ', ' \ ' +area_code+ ' \ ', ' \ ' +area_name+ ' \ ', ' \ ' +center_point+ ' \ ', ' \ ' + Area_parentcode+ '))
Cursor.execute (SQL) #执行sql
Conn.commit () #提交数据
Print ("Success")
if __name__ = = ' __main__ ':
Sql_server_data=sqlserver ()
Sql_server_data.insert_sql_server ()

Oracle methods:

To read a data method:

#!-*-Encoding:utf-8-*-
Import Cx_oracle,uuid
From class_area.class_readconf import readdate
Arearead_1=eval (readdate (' oracle.conf ', ' DATABASE ', ' config_1 '). ReadData ())
Area_read=readdate (' area.conf ', ' areas ', ' Config '). ReadData ()
Area_read_2=eval (Area_read)
Class Mysqlquerydata:
def __init__ (self,mysqlsentence):
Self.mysqlsentence = Mysqlsentence
def mysqlconnect (self):
#连接数据库
#strConnection = eval (arearead_1)
#conn = Cx_oracle.connect (' User name/password @ Database IP: Port number/database name ')
#cnn =cx_oracle.connect (' Newleader/[email protected]:1521/orcl ')
data_1=arearead_1[' user ']+ '/' +arearead_1[' password ']+ ' @ ' +arearead_1[' host ']+ ': ' +arearead_1[' Port ']+ '/' + arearead_1[' database '
Cnn=cx_oracle.connect (data_1)
#使用cursor方法获取游标
Cursor=cnn.cursor ()
#cursor =cnn.cursor (buffered=true) #当SQL查询语句是查询所有的, and then call the Fetchone () method, then you need to add buffered=true, otherwise it will be an error.
# Execute SQL statements using the Execute method
Cursor.execute (self.mysqlsentence)
#使用fetchall方法获取所有数据
Data=cursor.fetchall ()
#读取一条数据
#data =cursor.fetchone ()
#关闭游标
Cursor.close ()
#关闭数据库连接
Cnn.close ()
Return data
if __name__ = = "__main__":
Mysqlquerydata = Mysqlquerydata ("SELECT * from T_sys_area")
Print (Mysqlquerydata.mysqlconnect ())

Insert Data method:
Class Oracleinsertdata ():
def oracleconnect (self):
data_1=arearead_1[' user ']+ '/' +arearead_1[' password ']+ ' @ ' +arearead_1[' host ']+ ': ' +arearead_1[' Port ']+ '/' + arearead_1[' database '
Cnn=cx_oracle.connect (data_1)
Cursor=cnn.cursor ()
For Data_row in range (len (area_read_2)):
area_code=area_read_2[data_row][' CODE ']
area_name=area_read_2[data_row][' NAME ']
Center_point= ",". Join ((area_read_2[data_row][' latitude '],area_read_2[data_row][' longitude '))
area_parentcode=area_read_2[data_row][' Parentcode ']
Sql= (' INSERT into T_sys_area (id,area_code,area_name,area_parentcode,center_point) VALUES (%s,%s,%s,%s,%s) '% (' \ ' + STR (UUID.UUID1 ()). Replace ('-, ') + ' \ ', ' \ ' +area_code+ ' \ ', ' \ ' +area_name+ ' \ ', ' \ ' +area_parentcode+ ' \ ', ' \ ' + Center_point+ '))
Cursor.execute (SQL)
Cnn.commit ()
Cursor.close ()
#关闭数据库连接
Cnn.close ()

Print ("Success")
if __name__ = = "__main__":
Oracleinsertdata=oracleinsertdata ()
Oracleinsertdata.oracleconnect ()
