如何在MySQL中高效对比两个数据库的差异？
MySQL中对比两个数据库，可以使用如下SQL语句：，，“sql，SELECT ‘db1’ as db, table_name, column_name, data_type, column_type，FROM information_schema.columns，WHERE table_schema = ‘db1’ AND table_name = ‘table_name’，UNION ALL，SELECT ‘db2’ as db, table_name, column_name, data_type, column_type，FROM information_schema.columns，WHERE table_schema = ‘db2’ AND table_name = ‘table_name’;，`，，将db1和db2替换为要对比的数据库名称，将table_name`替换为要对比的表名。
