How can I dump a MySQL database without using mysqldump in Python [closed]

Answer 1

I have solved this problem.

import MySQLdb
import os
import datetime

con = MySQLdb.connect(host='localhost', user='root', passwd='password', db='test')
cur = con.cursor()

cur.execute("SHOW TABLES")
data = ""
tables = []
for table in cur.fetchall():
    tables.append(table[0])

for table in tables:
    data += "DROP TABLE IF EXISTS `" + str(table) + "`;"

    cur.execute("SHOW CREATE TABLE `" + str(table) + "`;")
    data += "\n" + str(cur.fetchone()[1]) + ";\n\n"

    cur.execute("SELECT * FROM `" + str(table) + "`;")
    for row in cur.fetchall():
        data += "INSERT INTO `" + str(table) + "` VALUES("
        first = True
        for field in row:
            if not first:
                data += ', '
            data += '"' + str(field) + '"'
            first = False


        data += ");\n"
    data += "\n\n"

now = datetime.datetime.now()
filename = str(os.getenv("HOME")) + "/backup_" + now.strftime("%Y-%m-%d_%H:%M") + ".sql"

FILE = open(filename,"w")
FILE.writelines(data)
FILE.close()

Seem to work well from a little testing.

I would advise MySQLdb - it provides a MySQL API for Python.

However, most probably the API does an indirect call to mysqldump. You don't want to call mysqldump directly or at all?

You might also want to check out Dump tables and data where the exact procedure to dump the table structure and data (down the page) without MySQLdb is shown.
