网上找了很多资料。发现都是有问题的。

比较接近要求有的。http://stackoverflow.com/questions/18671/quick-easy-way-to-migrate-sqlite3-to-mysql

在他基础上进行改造。

python代码

import re
import fileinput

def this_line_is_useless(line):
    useless_es = [
            'BEGIN TRANSACTION','COMMIT','sqlite_sequence','CREATE UNIQUE INDEX',]
    for useless in useless_es:
        if re.search(useless,line):
            return True

def has_primary_key(line):
    return bool(re.search(r'PRIMARY KEY',line))

searching_for_end = False
for line in fileinput.input():
    if this_line_is_useless(line): continue

    if re.match(r".*,''\);",line):
        line = re.sub(r"''\);",r'``);',line)
    if re.match(r'^CREATE TABLE.*',line):
        searching_for_end = True

    m = re.search('CREATE TABLE "?([a-z0-9_]*)"?(.*)',line)
    if m:
        name,sub = m.groups()
        line = "DROP TABLE IF EXISTS %(name)s;\nCREATE TABLE IF NOT EXISTS `%(name)s`%(sub)s\n"
        line = line % dict(name=name,sub=sub)
    else:
        m = re.search('INSERT INTO "([a-z0-9_]*)"(.*)',line)
        if m:
            line = 'INSERT INTO %s%s\n' % m.groups()
            line = line.replace('"',r'\"')
            line = line.replace('"',"'")
    line = re.sub(r"([^'])'t'(.)","\1THIS_IS_TRUE\2",line)
    line = line.replace('THIS_IS_TRUE','1')
    line = re.sub(r"([^'])'f'(.)","\1THIS_IS_FALSE\2",line)
    line = line.replace('THIS_IS_FALSE','0')
    if searching_for_end:
        if re.search(r"integer(?:\s+\w+)*\s*PRIMARY KEY(?:\s+\w+)*\s*,",line):
            line = line.replace("PRIMARY KEY","PRIMARY KEY AUTO_INCREMENT")
        line = line.replace('"','`').replace("'",'`')

    if re.match(r".*,``\);",line):
        line = re.sub(r'``\);',r"'');",line)

    if searching_for_end and re.match(r'.*\);',line):
        searching_for_end = False

    if re.match(r"CREATE INDEX",line):
        line = re.sub('"','`',line)
    
    if re.match(r'ANALYZE sqlite_master',line):
        line = ''
    
    if re.match(r'INSERT INTO sqlite_stat1',line):
        line = ''

    if line is not None:
        print line,

sqlite3 your.db .dump | python dump_for_MysqL.py > dump.sql

然后导入dump.sql执行。ok了。

其中可能会出现错误

varchar(64,0)

手工修改为varchar(64)
