如何查询MySQL错误代码

  作者:zhanhailiang 日期:2013-03-08

MySQL专门为错误代码提供perror工具来查询错误代码的含义。

如下：

zhanhailiang@linux-06bq:/usr/local/services/mysql/bin> ./perror --help
./perror Ver 2.11, for linux2.6 (i686)
This software comes with ABSOLUTELY NO WARRANTY. This is free software,

Print a description for a system error code or a MySQL error code.
If you want to get the error for a negative error code, you should use
-- before the first error code to tell perror that there was no more options.
 
Usage: ./perror [OPTIONS] [ERRORCODE [ERRORCODE...]]
  -?, --help          Displays this help and exits.
  -I, --info          Synonym for --help.
  -a, --all           Print all the error messages and the number.
  -s, --silent        Only print the error message.
  -v, --verbose       Print error code and message (default).
                      (Defaults to on; use --skip-verbose to disable.)
  -V, --version       Displays version information and exits.
 
Variables (--variable-name=value)
and boolean options {FALSE|TRUE}  Value (after reading options)
--------------------------------- ----------------------------------------
all                               FALSE
verbose                           TRUE
zhanhailiang@linux-06bq:/usr/local/services/mysql/bin> ./perror -s 1677
Column %d of table '%-.192s.%-.192s' cannot be converted from type '%-.32s' to type '%-.32s'
