Thought I would try my hand at some SQL programming with Python, I was stuck using a Windows machine(BLAH) I wanted to setup a MySQL database and 1 table for testing. I am on a Windows machine so I installed WAMP which is a Windows Apache Mysql Php server. You can get the installer for Windows here:
\nhttp:\/\/www.wampserver.com\/en\/<\/a><\/p>\n

You can get the python library \/ module here:<\/p>\n

Mysql Python<\/a>
\nUsing PhpMyAdmin I setup a database and added the table.<\/p>\n

\"mysql\"<\/p>\n

As you can see I created a function that added data into my new database. I pass it 4 parameters, id-name-dept-salary, when you execute this script the database gets populated with the correct data. Pretty cool!!<\/p>\n

#!\/usr\/bin\/python\r\nfrom mysql import connector\r\nimport optparse\r\n\r\nparser = optparse.OptionParser()\r\nparser.add_option('-i', action=\"store\", help=\"Enter Job ID#\", type=\"int\")\r\nparser.add_option('-n', action=\"store\", help=\"Enter Employee Name\", type=\"string\")\r\nparser.add_option('-d', action=\"store\", help=\"Enter Department\", type=\"string\")\r\nparser.add_option('-s', action=\"store\", help=\"Enter Salary\", type=\"int\")\r\noptions, args = parser.parse_args()\r\n\r\ndef databaseAdd(id,name,dept,salary):\r\n    con = connector.Connect(user='jason',\r\n                            password='password',\r\n                            database='jason',\r\n                            host='localhost')\r\n    c = con.cursor()\r\n    table_name = \"employee\"\r\n    insert = \"INSERT INTO \" + table_name + \" (id,name,dept,salary) \\\r\n    VALUES (%s, %s, %s, %s)\"\r\n    data_value = (id,name,dept,salary)\r\n    c.execute(insert, data_value)\r\n    con.commit()\r\n    c.close()\r\n    con.close()\r\n\r\ndatabaseAdd(options.i ,options.n,options.d,options.s)\r\n\r\n\r\n<\/pre>\n
Here is how you can see the help and call the command properly:
\n\"help<\/p>\n
Here is what you can see when performing a select * from the table.
\n\"database<\/p>\n
Here is the awesome IDE pyCharm and the results from running the code.
\n\"pycharm\"
\nHere is an example of how to query that database from the table.<\/p>\n
from mysql import connector\r\nimport sys\r\nimport optparse\r\n\r\n\r\nparser = optparse.OptionParser()\r\nparser.add_option('--id', action=\"store\", help=\"Enter ID number\", type=\"int\")\r\noptions, args = parser.parse_args()\r\n\r\n\r\ntry:\r\n    cnx = connector.Connect(user='jason',\r\n                        password='password',\r\n                        database='jason',\r\n                        host='localhost')\r\nexcept connector.Error as err:\r\n    print \"Connection to Database Failed\"\r\n    print err\r\n    sys.exit(1)\r\n\r\n\r\ncursor = cnx.cursor()\r\nquery = \"SELECT * from employee WHERE id='%s'\" % options.id\r\ncursor.execute(query)\r\nfor row in cursor:\r\n    print row\r\n\r\n<\/pre>\n
Here is the output of the fetch command using ID as a parameter:
\n\"database<\/p>\n
Took me a while to figure out the syntax, so hopefully this helps someone.
