.SH "NAME"
mysqldbimport \- Import Object Definitions or Data into a Databases
.SH "SYNOPSIS"

\fBmysqldbimport [\fR\fB\fIoptions\fR\fR\fB] \fR\fB\fIimport_file\fR\fR\fB \&.\&.\&.\fR
.SH "DESCRIPTION"
.PP
This utility imports metadata (object definitions) or data or both for one or more databases from one or more files\&.
.PP
If an object exists on the destination server with the same name as an imported object, it is dropped first before importing the new object\&.
.PP
To skip objects by type, use the
\fB\-\-skip\fR
option with a list of the objects to skip\&. This enables you to extract a particular set of objects, say, for importing only events (by excluding all other types)\&. Similarly, to skip creation of
\fBUPDATE\fR
statements for
BLOB
data, specify the
\fB\-\-skip\-blobs\fR
option\&.
.PP
To specify the input format, use one of the following values with the
\fB\-\-format\fR
option\&. These correspond to the output formats of the
\fBmysqldbexport\fR
utility:
.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.sp -1
.IP \(bu 2.3
.\}
\fBsql\fR
(default)
.sp
Input consists of SQL statements\&. For definitions, this consists of the appropriate
\fBCREATE\fR
and
\fBGRANT\fR
statements\&. For data, this is an
\fBINSERT\fR
statement (or bulk insert if the
\fB\-\-bulk\-insert\fR
option is specified)\&.
.RE
.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.sp -1
.IP \(bu 2.3
.\}
\fBgrid\fR
.sp
Display output in grid or table format like that of the
\fBmysql\fR
monitor\&.
.RE
.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.sp -1
.IP \(bu 2.3
.\}
\fBcsv\fR
.sp
Input is formatted in comma\-separated values format\&.
.RE
.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.sp -1
.IP \(bu 2.3
.\}
\fBraw_csv\fR
.sp
Input is a simple CSV file containing uniform rows with values separated with commas\&. The file can contain a header (the first row) that lists the table columns\&. The option
\fB\-\-table\fR
is required to use this format\&.
.RE
.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.sp -1
.IP \(bu 2.3
.\}
\fBtab\fR
.sp
Input is formatted in tab\-separated format\&.
.RE
.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.sp -1
.IP \(bu 2.3
.\}
\fBvertical\fR
.sp
Display output in single\-column format like that of the
\eG
command for the
\fBmysql\fR
monitor\&.
.RE
.PP
To indicate that input in
\fBcsv\fR
or
\fBtab\fR
format does not contain column headers, specify the
\fB\-\-no\-headers\fR
option\&.
.PP
To turn off all feedback information, specify the
\fB\-\-quiet\fR
option\&.
.PP
By default, the utility creates each table on the destination server using the same storage engine as the original table\&. To override this and specify the storage engine to use for all tables created on the destination server, use the
\fB\-\-new\-storage\-engine\fR
option\&. If the destination server supports the new engine, all tables use that engine\&.
.PP
To specify the storage engine to use for tables for which the destination server does not support the original storage engine on the source server, use the
\fB\-\-default\-storage\-engine\fR
option\&.
.PP
The
\fB\-\-new\-storage\-engine\fR
option takes precedence over
\fB\-\-default\-storage\-engine\fR
if both are given\&.
.PP
If the
\fB\-\-new\-storage\-engine\fR
or
\fB\-\-default\-storage\-engine\fR
option is given and the destination server does not support the specified storage engine, a warning is issued and the server\*(Aqs default storage engine setting is used instead\&.
.PP
You must provide connection parameters (user, host, password, and so forth) for an account that has the appropriate privileges to access all objects in the operation\&. For details, see NOTES\&.
.PP
If you attempt to import databases on a server with GTIDs enabled (GTID_MODE = ON), a warning will be generated if the import file did not include the GTID statements generated by mysqldbexport\&.
.PP
The utility will also generate a warning if you import databases on a server without GTIDs enabled and there are GTID statements present in the file\&. Use the
\fB\-\-skip\-gtid\fR
option to ignore the GTID statements\&.
.PP
To make the most use of GTIDs and export/import, you should export all of the databases on the server with the
\fB \-\-all\fR
option\&. This will generate an export file with all of the databases and the GTIDs executed to that point\&. Importing this file on another server will ensure that server has all of the data as well as all of the GTIDs recorded correctly in its logs\&.
      OPTIONS
.PP
\fBmysqldbimport\fR
accepts the following command\-line options:

.sp
Specify the input format\&. Permitted format values are
\fBsql\fR,

\fBdefinitions\fR\&.
.sp
If you attempt to import objects into an existing database, the result depends on the import format\&. If the format is
\fBdefinitions\fR
or
\fBboth\fR, an error occurs unless
\fB\-\-drop\-first\fR

.RE
      NOTES
.PP
The login user must have the appropriate permissions to create new objects, access (read) the
mysql
database, and grant privileges\&. If a database to be imported already exists, the user must have read permission for it, which is needed to check the existence of objects in the database\&.
.PP
Actual privileges needed may differ from installation to installation depending on the security privileges present and whether the database contains certain objects such as views or events and whether binary logging is enabled\&.
.PP
Some combinations of the options may result in errors during the operation\&. For example, excluding tables but not views may result in an error when a view is imported\&.
.PP
The
\fB\-\-new\-storage\-engine\fR
and
\fB\-\-default\-storage\-engine\fR
options apply to all destination tables in the operation\&.
.PP
For the
\fB\-\-format\fR
and
\fB\-\-import\fR
options, the permitted values are not case sensitive\&. In addition, values may be specified as any unambiguous prefix of a valid value\&. For example,
\fB\-\-format=g\fR
specifies the grid format\&. An error occurs if a prefix matches more than one valid value\&.
.PP
When importing data and including the GTID commands, you may encounter an error similar to "GTID_PURGED can only be set when GTID_EXECUTED is empty"\&. This occurs because the destination server is not in a clean replication state\&. To aleviate this problem, you can issue a "RESET MASTER" command on the destination prior to executing the import\&.
.PP
The path to the MySQL client tools should be included in the PATH environment variable in order to use the authentication mechanism with login\-paths\&. This will allow the utility to use the my_print_defaults tools which is required to read the login\-path values from the login configuration file (\&.mylogin\&.cnf)\&.
      EXAMPLES
.PP
To import the metadata from the
util_test
database to the server on the local host using a file in CSV format, use this command:
.sp
.if n \{\
.RS 4
.\}
.nf
$ mysqldbimport \-\-server=root@localhost \-\-import=definitions \e
  \-\-format=csv data\&.csv
# Source on localhost: \&.\&.\&. connected\&.
# Importing definitions from data\&.csv\&.
#\&.\&.\&.done\&.
.fi
.if n \{\
.RE
.\}
.PP
Similarly, to import the data from the
util_test
database to the server on the local host, importing the data using bulk insert statements, use this command:
.sp
.if n \{\
.RS 4
.\}
.nf
$ mysqldbimport \-\-server=root@localhost \-\-import=data \e
  \-\-bulk\-insert \-\-format=csv data\&.csv
# Source on localhost: \&.\&.\&. connected\&.
# Importing data from data\&.csv\&.
#\&.\&.\&.done\&.
.fi
.if n \{\
.RE
.\}
.PP
To import both data and definitions from the
util_test
database, importing the data using bulk insert statements from a file that contains SQL statements, use this command:
.sp
.if n \{\
.RS 4
.\}
.nf
$ mysqldbimport \-\-server=root@localhost \-\-import=both \-\-bulk\-insert \-\-format=sql data\&.sql
# Source on localhost: \&.\&.\&. connected\&.
# Importing definitions and data from data\&.sql\&.
#\&.\&.\&.done\&.
