mysql--help不可用
1、问题描述:
执行help语句时没有得到相应的返回只是提示检查相关表是不是已经加载:
mysql> help contents; Nothing found Please check if 'help tables' are loaded. mysql>
2、查看mysql官方后发现这些表相关的sql语句在fill_help_tables.sql 这个文件中;只是加载这个文件中的内容到mysql 库就行了
mysql -h127.0.0.1 -uxxxx -pxxxx mysql </usr/local/mysql-5.6.31-linux-glibc2.5-x86_64/share/fill_help_tables.sql
3、加载完成之后help就可用了
mysql> help contents; You asked for help about help category: "Contents" For more information, type 'help <item>', where <item> is one of the following categories: Account Management Administration Compound Statements Data Definition Data Manipulation Data Types Functions Functions and Modifiers for Use with GROUP BY Geographic Features Help Metadata Language Structure Plugins Procedures Storage Engines Table Maintenance Transactions User-Defined Functions Utility
