1) Here are a list of terms/words that I think should be fixed in the translation: statement 语句 prepared statment 预处理语句 partitioning/partition function 分区函数 reference 引用 table 表 table type 表类型 underlying table 底层表 derived table 衍生表 native 本地 key 键 schema 数据库 (synonym for database) schedule/scheduler 调度/调度器 syntax 语法 context 上下文 collation 排序规则 grant 授予，授权 constrain 约束 truncate 截短 abort 中止 specify/specified 指定(的) incorrect 错误(的) count 个数 packet 数据包 clause 子句 checksum 校验和 relay log 中继日志 backup progress log 备份进度日志 creation contex 创建上下文 group function 分组函数 2) I think it's better to not translate commands, variable, arguments, options or data types, such as CREATE TABLE, ALTER VIEW, BLOB, TEXT, DATE, 'max_binlog_cache_size', --skip-name-resolve, etc. Just leave them as they are. As a simple rule, I think every thing that's in all upper cases, do not need to be translated. For example: ER_TRANS_CACHE_FULL eng "Multi-statement transaction required more than 'max_binlog_cache_size' bytes of storage; increase this mysqld variable and try again" chs "多语句的事务需要超过 'max_binlog_cache_size' 字节的存储空间，请增加该变量后重试" ER_SLAVE_MUST_STOP eng "This operation cannot be performed with a running slave; run STOP SLAVE first" chs "该操作不能在从服务器运行时执行，请先运行 STOP SLAVE" ER_BAD_SLAVE eng "The server is not configured as slave; fix with CHANGE MASTER TO" chs "该服务器未配置为从服务器，请使用 CHANGE MASTER TO" ER_READ_ONLY_TRANSACTION 25000 eng "Update locks cannot be acquired during a READ UNCOMMITTED transaction" chs "无法在 READ UNCOMMITTED 的事务中取得更新锁定" 3) Here are some sentences that I'd prefer to be translated something as following: ER_EMPTY_QUERY 42000 eng "Query was empty" chs "查询为空" ER_MULTIPLE_PRI_KEY 42000 S1009 eng "Multiple primary key defined" chs "定义了多个主键" ER_UPDATE_TABLE_USED eng "You can't specify target table '%-.192s' for update in FROM clause" chs "不能在 FROM 子句中指定用于更新的表 '%-.192s'" ER_NO_UNIQUE_LOGFILE eng "Can't generate a unique log-filename %-.200s.(1-999)\n" chs "无法生成唯一的日志文件名 %-.200s.(1-999)\n" # Please note the '.' is the separator of file name and extension ER_TOO_BIG_SELECT 42000 eng "The SELECT would examine more than MAX_JOIN_SIZE rows; check your WHERE and use SET SQL_BIG_SELECTS=1 or SET SQL_MAX_JOIN_SIZE=# if the SELECT is okay" chs "该 SELECT 将检查超过 MAX_JOIN_SIZE 行，请检查 WHERE 条件，如果该 SELECT 没有问题，并使用 SET SQL_BIG_SELECTS=1 或 SET SQL_MAX_JOIN_SIZE=#" ER_TOO_MANY_TABLES eng "Too many tables; MySQL can only use %d tables in a join" chs "表过多，MySQL 在一个连接中最多只能使用 %d 个表" ER_TOO_BIG_ROWSIZE 42000 eng "Row size too large.
