有個問題
1、字符集CHARACTER 是<UNKNOWN>。如果想要得到字段字符集設置。還得加上參數連上mysql。
2、由於不知道字符集所以char 長度乘以3
解決
mysqlfrm --help 查看下參數
Options:
--version show program's version number and exit
--license display program's license and exit
--help
--basedir=BASEDIR the base directory for the server
--diagnostic read the frm files byte-by-byte to form the CREATE
statement. May require the --server or --basedir
options to decipher character set information
--new-storage-engine=NEW_ENGINE
change ENGINE clause to use this engine.
--frmdir=FRMDIR save the new .frm files in this directory. Used and
valid with --new-storage-engine only.
--port=PORT Port to use for the spawned server.
-s, --show-stats show file statistics and general table information.
--server=SERVER connection information for the server in the form:
<user>[:<password>]@<host>[:<port>][:<socket>] or
<login-path>[:<port>][:<socket>] (optional) - if
provided, the storage engine and character set
information will be validated against this server.
--user=USER user account to launch spawned server. Required if
running as root user. Used only in the default mode.
--start-timeout=START_TIMEOUT
Number of seconds to wait for spawned server to start.
Default = 10.
-v, --verbose control how much information is displayed. e.g., -v =
verbose, -vv = more verbose, -vvv = debug
-q, --quiet turn off all messages for quiet execution.
--ssl-ca=SSL_CA path to a file that contains a list of trusted SSL
CAs.
--ssl-cert=SSL_CERT name of the SSL certificate file to use for
establishing a secure connection.
--ssl-key=SSL_KEY name of the SSL key file to use for establishing a
secure connection.
--ssl=SSL specifies if the server connection requires use of
SSL. If an encrypted connection cannot be established,
the connection attempt fails. By default 0 (SSL not
required).
需要加上--server參數連上mysql。
mysqlfrm --diagnostic user.frm --server=root:1111aaA_@localhost
如下輸出的表結構語句是完整的。

但是既然能連上mysql服務，我們爲啥要用mysqlfrm 呢？。。。的確這是mysqlfrm 工具的一個問題。
