6 mysqlimport - a data import program
7
9 mysqlimport [options] db_name textfile1 ...
10
12 The mysqlimport client provides a command-line interface to the LOAD
13 DATA SQL statement. Most options to mysqlimport correspond directly to
14 clauses of LOAD DATA syntax. See Section 13.2.7, “LOAD DATA Syntax”.
15 Invoke mysqlimport like this:
17 shell> mysqlimport [options] db_name textfile1 [textfile2 ...]
19 For each text file named on the command line, mysqlimport strips any
21 extension from the file name and uses the result to determine the name
22 of the table into which to import the file's contents. For example,
23 files named patient.txt, patient.text, and patient all would be
24 imported into a table named patient.
25 mysqlimport supports the following options, which can be specified on
27 the command line or in the [mysqlimport] and [client] groups of an
28 option file. For information about option files used by MySQL programs,
29 see Section 4.2.7, “Using Option Files”.
30 · --help, -?
32 Display a help message and exit.
34 · --bind-address=ip_address
36 On a computer having multiple network interfaces, use this option
38 to select which interface to use for connecting to the MySQL
39 server.
40 · --character-sets-dir=dir_name
42 The directory where character sets are installed. See
44 Section 10.14, “Character Set Configuration”.
45 · --columns=column_list, -c column_list
47 This option takes a list of comma-separated column names as its
49 value. The order of the column names indicates how to match data
50 file columns with table columns.
51 · --compress, -C
53 Compress all information sent between the client and the server if
55 both support compression.
56 · --debug[=debug_options], -# [debug_options]
58 Write a debugging log. A typical debug_options string is
60 d:t:o,file_name. The default is d:t:o.
61 · --debug-check
63 Print some debugging information when the program exits.
65 · --debug-info
67 Print debugging information and memory and CPU usage statistics
69 when the program exits.
70 · --default-character-set=charset_name
72 Use charset_name as the default character set. See Section 10.14,
74 “Character Set Configuration”.
75 · --default-auth=plugin
77 A hint about the client-side authentication plugin to use. See
79 Section 6.3.10, “Pluggable Authentication”.
80 · --defaults-extra-file=file_name
82 Read this option file after the global option file but (on Unix)
84 before the user option file. If the file does not exist or is
85 otherwise inaccessible, an error occurs. file_name is interpreted
86 relative to the current directory if given as a relative path name
87 rather than a full path name.
88 For additional information about this and other option-file
90 options, see Section 4.2.8, “Command-Line Options that Affect
91 Option-File Handling”.
92 · --defaults-file=file_name
94 Use only the given option file. If the file does not exist or is
96 otherwise inaccessible, an error occurs. file_name is interpreted
97 relative to the current directory if given as a relative path name
98 rather than a full path name.
99 Exception: Even with --defaults-file, client programs read
101 .mylogin.cnf.
102 For additional information about this and other option-file
104 options, see Section 4.2.8, “Command-Line Options that Affect
105 Option-File Handling”.
106 · --defaults-group-suffix=str
108 Read not only the usual option groups, but also groups with the
110 usual names and a suffix of str. For example, mysqlimport normally
111 reads the [client] and [mysqlimport] groups. If the
112 --defaults-group-suffix=_other option is given, mysqlimport also
113 reads the [client_other] and [mysqlimport_other] groups.
114 For additional information about this and other option-file
116 options, see Section 4.2.8, “Command-Line Options that Affect
117 Option-File Handling”.
118 · --delete, -D
120 Empty the table before importing the text file.
122 · --enable-cleartext-plugin
124 Enable the mysql_clear_password cleartext authentication plugin.
126 (See Section 6.5.1.4, “Client-Side Cleartext Pluggable
127 Authentication”.)
128 · --fields-terminated-by=..., --fields-enclosed-by=...,
130 --fields-optionally-enclosed-by=..., --fields-escaped-by=...
131 These options have the same meaning as the corresponding clauses
133 for LOAD DATA. See Section 13.2.7, “LOAD DATA Syntax”.
134 · --force, -f
136 Ignore errors. For example, if a table for a text file does not
138 exist, continue processing any remaining files. Without --force,
139 mysqlimport exits if a table does not exist.
140 · --get-server-public-key
142 Request from the server the public key required for RSA key
144 pair-based password exchange. This option applies to clients that
145 that authenticate with the caching_sha2_password authentication
146 plugin. For that plugin, the server does not send the public key
147 unless requested. This option is ignored for accounts that do not
148 authenticate with that plugin. It is also ignored if RSA-based
149 password exchange is not used, as is the case when the client
150 connects to the server using a secure connection.
151 If --server-public-key-path=file_name is given and specifies a
153 valid public key file, it takes precedence over
154 --get-server-public-key.
155 For information about the caching_sha2_password plugin, see
157 Section 6.5.1.3, “Caching SHA-2 Pluggable Authentication”.
158 · --host=host_name, -h host_name
160 Import data to the MySQL server on the given host. The default host
162 is localhost.
163 · --ignore, -i
165 See the description for the --replace option.
167 · --ignore-lines=N
169 Ignore the first N lines of the data file.
171 · --lines-terminated-by=...
173 This option has the same meaning as the corresponding clause for
175 LOAD DATA. For example, to import Windows files that have lines
176 terminated with carriage return/linefeed pairs, use
177 --lines-terminated-by="\r\n". (You might have to double the
178 backslashes, depending on the escaping conventions of your command
179 interpreter.) See Section 13.2.7, “LOAD DATA Syntax”.
180 · --local, -L
182 By default, files are read by the server on the server host. With
184 this option, mysqlimport reads input files locally on the client
185 host. Enabling local data loading also requires that the server
186 permits it; see Section 6.1.6, “Security Issues with LOAD DATA
187 LOCAL”
188 · --lock-tables, -l
190 Lock all tables for writing before processing any text files. This
192 ensures that all tables are synchronized on the server.
193 · --login-path=name
195 Read options from the named login path in the .mylogin.cnf login
197 path file. A “login path” is an option group containing options
198 that specify which MySQL server to connect to and which account to
199 authenticate as. To create or modify a login path file, use the
200 mysql_config_editor utility. See mysql_config_editor(1).
201 For additional information about this and other option-file
203 options, see Section 4.2.8, “Command-Line Options that Affect
204 Option-File Handling”.
205 · --low-priority
207 Use LOW_PRIORITY when loading the table. This affects only storage
209 engines that use only table-level locking (such as MyISAM, MEMORY,
210 and MERGE).
211 · --no-defaults
213 Do not read any option files. If program startup fails due to
215 reading unknown options from an option file, --no-defaults can be
216 used to prevent them from being read.
217 The exception is that the .mylogin.cnf file, if it exists, is read
219 in all cases. This permits passwords to be specified in a safer way
220 than on the command line even when --no-defaults is used.
221 (.mylogin.cnf is created by the mysql_config_editor utility. See
222 mysql_config_editor(1).)
223 For additional information about this and other option-file
225 options, see Section 4.2.8, “Command-Line Options that Affect
226 Option-File Handling”.
227 · --password[=password], -p[password]
229 The password to use when connecting to the server. If you use the
231 short option form (-p), you cannot have a space between the option
232 and the password. If you omit the password value following the
233 --password or -p option on the command line, mysqlimport prompts
234 for one.
235 Specifying a password on the command line should be considered
237 insecure. See Section 6.1.2.1, “End-User Guidelines for Password
238 Security”. You can use an option file to avoid giving the password
239 on the command line.
240 · --pipe, -W
242 On Windows, connect to the server using a named pipe. This option
244 applies only if the server supports named-pipe connections.
245 · --plugin-dir=dir_name
247 The directory in which to look for plugins. Specify this option if
249 the --default-auth option is used to specify an authentication
250 plugin but mysqlimport does not find it. See Section 6.3.10,
251 “Pluggable Authentication”.
252 · --port=port_num, -P port_num
254 The TCP/IP port number to use for the connection.
256 · --print-defaults
258 Print the program name and all options that it gets from option
260 files.
261 For additional information about this and other option-file
263 options, see Section 4.2.8, “Command-Line Options that Affect
264 Option-File Handling”.
265 · --protocol={TCP|SOCKET|PIPE|MEMORY}
267 The connection protocol to use for connecting to the server. It is
269 useful when the other connection parameters normally would cause a
270 protocol to be used other than the one you want. For details on the
271 permissible values, see Section 4.2.2, “Connecting to the MySQL
272 Server”.
273 · --replace, -r
275 The --replace and --ignore options control handling of input rows
277 that duplicate existing rows on unique key values. If you specify
278 --replace, new rows replace existing rows that have the same unique
279 key value. If you specify --ignore, input rows that duplicate an
280 existing row on a unique key value are skipped. If you do not
281 specify either option, an error occurs when a duplicate key value
282 is found, and the rest of the text file is ignored.
283 · --secure-auth
285 This option was removed in MySQL 8.0.3.
287 · --server-public-key-path=file_name
289 The path name to a file containing a client-side copy of the public
291 key required by the server for RSA key pair-based password
292 exchange. The file must be in PEM format. This option applies to
293 clients that authenticate with the sha256_password or
294 caching_sha2_password authentication plugin. This option is ignored
295 for accounts that do not authenticate with one of those plugins. It
296 is also ignored if RSA-based password exchange is not used, as is
297 the case when the client connects to the server using a secure
298 connection.
299 If --server-public-key-path=file_name is given and specifies a
301 valid public key file, it takes precedence over
302 --get-server-public-key.
303 For sha256_password, this option applies only if MySQL was built
305 using OpenSSL.
306 For information about the sha256_password and caching_sha2_password
308 plugins, see Section 6.5.1.2, “SHA-256 Pluggable Authentication”,
309 and Section 6.5.1.3, “Caching SHA-2 Pluggable Authentication”.
310 · --shared-memory-base-name=name
312 On Windows, the shared-memory name to use, for connections made
314 using shared memory to a local server. The default value is MYSQL.
315 The shared-memory name is case-sensitive.
316 The server must be started with the --shared-memory option to
318 enable shared-memory connections.
319 · --silent, -s
321 Silent mode. Produce output only when errors occur.
323 · --socket=path, -S path
325 For connections to localhost, the Unix socket file to use, or, on
327 Windows, the name of the named pipe to use.
328 · --ssl*
330 Options that begin with --ssl specify whether to connect to the
332 server using SSL and indicate where to find SSL keys and
333 certificates. See Section 6.4.2, “Command Options for Encrypted
334 Connections”.
335 · --ssl-fips-mode={OFF|ON|STRICT} Controls whether to enable FIPS
337 mode on the client side. The --ssl-fips-mode option differs from
338 other --ssl-xxx options in that it is not used to establish
339 encrypted connections, but rather to affect which cryptographic
340 operations are permitted. See Section 6.6, “FIPS Support”.
341 These --ssl-fips-mode values are permitted:
343 · OFF: Disable FIPS mode.
345 · ON: Enable FIPS mode.
347 · STRICT: Enable “strict” FIPS mode.
349 Note
352 If the OpenSSL FIPS Object Module is not available, the only
353 permitted value for --ssl-fips-mode is OFF. In this case,
354 setting --ssl-fips-mode to ON or STRICT causes the client to
355 produce a warning at startup and to operate in non-FIPS mode.
356 · --tls-ciphersuites=ciphersuite_list
358 For client programs, specifies which TLSv1.3 ciphersuites the
360 client permits for encrypted connections. The value is a list of
361 one or more colon-separated ciphersuite names. The ciphersuites
362 that can be named for this option depend on the SSL library used to
363 compile MySQL. For details, see Section 6.4.6, “Encrypted
364 Connection Protocols and Ciphers”.
365 This option was added in MySQL 8.0.16.
367 · --tls-version=protocol_list
369 The protocols the client permits for encrypted connections. The
371 value is a list of one or more comma-separated protocol names. The
372 protocols that can be named for this option depend on the SSL
373 library used to compile MySQL. For details, see Section 6.4.6,
374 “Encrypted Connection Protocols and Ciphers”.
375 · --user=user_name, -u user_name
377 The MySQL user name to use when connecting to the server.
379 · --use-threads=N
381 Load files in parallel using N threads.
383 · --verbose, -v
385 Verbose mode. Print more information about what the program does.
387 · --version, -V
389 Display version information and exit.
