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,
执行
sqlite3 your.db .dump | python dump_for_MysqL.py > dump.sql
之后联接数据库过程中需要设置联接以后编码为utf-8
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)
