Usage: mysqldump [OPTIONS] database [tables]
OR     mysqldump [OPTIONS] --databases [OPTIONS] DB1 [DB2 DB3...]
OR     mysqldump [OPTIONS] --all-databases [OPTIONS]Default options are read from the following files in the given order:
C:\Windows\my.ini C:\Windows\my.cnf C:\my.ini C:\my.cnf C:\Program Files\MySQL\MySQL Server 5.5\my.ini C:\Program Files\MySQL\MySQL Server 5.5\my.cnf J:\Workspace\TKA项目\TKA软件安装包实施方案\ref\Mysql_8.0.17_安装\Mysql_8.0.17_安装\my.ini J:\Workspace\TKA项目\TKA软件安装包实施方案\ref\Mysql_8.0.17_安装\Mysql_8.0.17_安装\my.cnf
The following groups are read: mysqldump client
The following options may be given as the first argument:
--print-defaults        Print the program argument list and exit.
--no-defaults           Don't read default options from any option file.
--defaults-file=#       Only read default options from the given file #.
--defaults-extra-file=# Read this file after the global files are read.-A, --all-databases Dump all the databases. This will be same as --databaseswith all databases selected.-Y, --all-tablespaces Dump all the tablespaces.-y, --no-tablespaces Do not dump any tablespace information.--add-drop-database Add a DROP DATABASE before each create.--add-drop-table    Add a DROP TABLE before each create.(Defaults to on; use --skip-add-drop-table to disable.)--add-locks         Add locks around INSERT statements.(Defaults to on; use --skip-add-locks to disable.)--allow-keywords    Allow creation of column names that are keywords.--apply-slave-statements Adds 'STOP SLAVE' prior to 'CHANGE MASTER' and 'STARTSLAVE' to bottom of dump.--character-sets-dir=name Directory for character set files.-i, --comments      Write additional information.(Defaults to on; use --skip-comments to disable.)--compatible=name   Change the dump to be compatible with a given mode. Bydefault tables are dumped in a format optimized forMySQL. Legal modes are: ansi, mysql323, mysql40,postgresql, oracle, mssql, db2, maxdb, no_key_options,no_table_options, no_field_options. One can use severalmodes separated by commas. Note: Requires MySQL serverversion 4.1.0 or higher. This option is ignored withearlier server versions.--compact           Give less verbose output (useful for debugging). Disablesstructure comments and header/footer constructs.  Enablesoptions --skip-add-drop-table --skip-add-locks--skip-comments --skip-disable-keys --skip-set-charset.-c, --complete-insert Use complete insert statements.-C, --compress      Use compression in server/client protocol.-a, --create-options Include all MySQL specific create options.(Defaults to on; use --skip-create-options to disable.)-B, --databases     Dump several databases. Note the difference in usage; inthis case no tables are given. All name arguments areregarded as database names. 'USE db_name;' will beincluded in the output.-#, --debug[=#]     This is a non-debug version. Catch this and exit.--debug-check       Check memory and open file usage at exit.--debug-info        Print some debug info at exit.--default-character-set=name Set the default character set.--delayed-insert    Insert rows with INSERT DELAYED.--delete-master-logs Delete logs on master after backup. This automaticallyenables --master-data.-K, --disable-keys  '/*!40000 ALTER TABLE tb_name DISABLE KEYS */; and'/*!40000 ALTER TABLE tb_name ENABLE KEYS */; will be putin the output.(Defaults to on; use --skip-disable-keys to disable.)--dump-slave[=#]    This causes the binary log position and filename of themaster to be appended to the dumped data output. Settingthe value to 1, will printit as a CHANGE MASTER commandin the dumped data output; if equal to 2, that commandwill be prefixed with a comment symbol. This option willturn --lock-all-tables on, unless --single-transaction isspecified too (in which case a global read lock is onlytaken a short time at the beginning of the dump - don'tforget to read about --single-transaction below). In allcases any action on logs will happen at the exact momentof the dump.Option automatically turns --lock-tables off.-E, --events        Dump events.-e, --extended-insert Use multiple-row INSERT syntax that include severalVALUES lists.(Defaults to on; use --skip-extended-insert to disable.)--fields-terminated-by=name Fields in the output file are terminated by the givenstring.--fields-enclosed-by=name Fields in the output file are enclosed by the givencharacter.--fields-optionally-enclosed-by=name Fields in the output file are optionally enclosed by thegiven character.--fields-escaped-by=name Fields in the output file are escaped by the givencharacter.-F, --flush-logs    Flush logs file in server before starting dump. Note thatif you dump many databases at once (using the option--databases= or --all-databases), the logs will beflushed for each database dumped. The exception is whenusing --lock-all-tables or --master-data: in this casethe logs will be flushed only once, corresponding to themoment all tables are locked. So if you want your dumpand the log flush to happen at the same exact moment youshould use --lock-all-tables or --master-data with--flush-logs.--flush-privileges  Emit a FLUSH PRIVILEGES statement after dumping the mysqldatabase.  This option should be used any time the dumpcontains the mysql database and any other database thatdepends on the data in the mysql database for properrestore. -f, --force         Continue even if we get an SQL error.-?, --help          Display this help message and exit.--hex-blob          Dump binary strings (BINARY, VARBINARY, BLOB) inhexadecimal format.-h, --host=name     Connect to host.--ignore-table=name Do not dump the specified table. To specify more than onetable to ignore, use the directive multiple times, oncefor each table.  Each table must be specified with bothdatabase and table names, e.g.,--ignore-table=database.table.--include-master-host-port Adds 'MASTER_HOST=<host>, MASTER_PORT=<port>' to 'CHANGEMASTER TO..' in dump produced with --dump-slave.--insert-ignore     Insert rows with INSERT IGNORE.--lines-terminated-by=name Lines in the output file are terminated by the givenstring.-x, --lock-all-tables Locks all tables across all databases. This is achievedby taking a global read lock for the duration of thewhole dump. Automatically turns --single-transaction and--lock-tables off.-l, --lock-tables   Lock all tables for read.(Defaults to on; use --skip-lock-tables to disable.)--log-error=name    Append warnings and errors to given file.--master-data[=#]   This causes the binary log position and filename to beappended to the output. If equal to 1, will print it as aCHANGE MASTER command; if equal to 2, that command willbe prefixed with a comment symbol. This option will turn--lock-all-tables on, unless --single-transaction isspecified too (in which case a global read lock is onlytaken a short time at the beginning of the dump; don'tforget to read about --single-transaction below). In allcases, any action on logs will happen at the exact momentof the dump. Option automatically turns --lock-tablesoff.--max-allowed-packet=# The maximum packet length to send to or receive fromserver.--net-buffer-length=# The buffer size for TCP/IP and socket communication.--no-autocommit     Wrap tables with autocommit/commit statements.-n, --no-create-db  Suppress the CREATE DATABASE ... IF EXISTS statement thatnormally is output for each dumped database if--all-databases or --databases is given.-t, --no-create-info Don't write table creation info.-d, --no-data       No row information.-N, --no-set-names  Same as --skip-set-charset.--opt               Same as --add-drop-table, --add-locks, --create-options,--quick, --extended-insert, --lock-tables, --set-charset,and --disable-keys. Enabled by default, disable with--skip-opt.--order-by-primary  Sorts each table's rows by primary key, or first uniquekey, if such a key exists.  Useful when dumping a MyISAMtable to be loaded into an InnoDB table, but will makethe dump itself take considerably longer.-p, --password[=name] Password to use when connecting to server. If password isnot given it's solicited on the tty.-W, --pipe          Use named pipes to connect to server.-P, --port=#        Port number to use for connection.--protocol=name     The protocol to use for connection (tcp, socket, pipe,memory).-q, --quick         Don't buffer query, dump directly to stdout.(Defaults to on; use --skip-quick to disable.)-Q, --quote-names   Quote table and column names with backticks (`).(Defaults to on; use --skip-quote-names to disable.)--replace           Use REPLACE INTO instead of INSERT INTO.-r, --result-file=name Direct output to a given file. This option should be usedin systems (e.g., DOS, Windows) that use carriage-returnlinefeed pairs (\r\n) to separate text lines. This optionensures that only a single newline is used.-R, --routines      Dump stored routines (functions and procedures).--set-charset       Add 'SET NAMES default_character_set' to the output.(Defaults to on; use --skip-set-charset to disable.)--shared-memory-base-name=name Base name of shared memory.--single-transaction Creates a consistent snapshot by dumping all tables in asingle transaction. Works ONLY for tables stored instorage engines which support multiversioning (currentlyonly InnoDB does); the dump is NOT guaranteed to beconsistent for other storage engines. While a--single-transaction dump is in process, to ensure avalid dump file (correct table contents and binary logposition), no other connection should use the followingstatements: ALTER TABLE, DROP TABLE, RENAME TABLE,TRUNCATE TABLE, as consistent snapshot is not isolatedfrom them. Option automatically turns off --lock-tables.--dump-date         Put a dump date to the end of the output.(Defaults to on; use --skip-dump-date to disable.)--skip-opt          Disable --opt. Disables --add-drop-table, --add-locks,--create-options, --quick, --extended-insert,--lock-tables, --set-charset, and --disable-keys.-S, --socket=name   The socket file to use for connection.--ssl               Enable SSL for connection (automatically enabled withother flags).--ssl-ca=name       CA file in PEM format (check OpenSSL docs, implies--ssl).--ssl-capath=name   CA directory (check OpenSSL docs, implies --ssl).--ssl-cert=name     X509 cert in PEM format (implies --ssl).--ssl-cipher=name   SSL cipher to use (implies --ssl).--ssl-key=name      X509 key in PEM format (implies --ssl).--ssl-verify-server-cert Verify server's "Common Name" in its cert againsthostname used when connecting. This option is disabled bydefault.--ssl-mode=name     SSL connection mode.-T, --tab=name      Create tab-separated textfile for each table to givenpath. (Create .sql and .txt files.) NOTE: This only worksif mysqldump is run on the same machine as the mysqldserver.--tables            Overrides option --databases (-B).--triggers          Dump triggers for each dumped table.(Defaults to on; use --skip-triggers to disable.)--tz-utc            SET TIME_ZONE='+00:00' at top of dump to allow dumping ofTIMESTAMP data when a server has data in different timezones or data is being moved between servers withdifferent time zones.(Defaults to on; use --skip-tz-utc to disable.)-u, --user=name     User for login if not current user.-v, --verbose       Print info about the various stages.-V, --version       Output version information and exit.-w, --where=name    Dump only selected records. Quotes are mandatory.-X, --xml           Dump a database as well formed XML.--plugin-dir=name   Directory for client-side plugins.--default-auth=name Default authentication client-side plugin to use.--enable-cleartext-plugin Enable/disable the clear text authentication plugin.Variables (--variable-name=value)

问题

使用Workbench导出sql文件，使用脚本导入到数据库，因为默认导出没有设置选项--hex-blob；导出部分乱码，读取出来的数据出错；

mysqldump -h localhost -uYYYYYY -pXXXXXX -t db t1>d:/table.sql

解决办法

十六进制导出

mysqldump --hex-blob -h localhost -uYYYYYY -pXXXXXX -t db t1>d:/table.sql

结果中blob字段为16进制串，比如：0x12563DA5752F;
