.SH "DESCRIPTION"
.PP
The
\fBmysqlimport\fR
client provides a command\-line interface to the
LOAD DATA INFILE
SQL statement\&. Most options to
\fBmysqlimport\fR
correspond directly to clauses of
LOAD DATA INFILE
syntax\&. See
Section\ \&12.2.6, \(lqLOAD DATA INFILE Syntax\(rq\&.
.PP
Invoke
\fBmysqlimport\fR
like this:
.sp
.if n \{\
.RS 4
.\}
.nf
shell> \fBmysqlimport [\fR\fB\fIoptions\fR\fR\fB] \fR\fB\fIdb_name\fR\fR\fB \fR\fB\fItextfile1\fR\fR\fB [\fR\fB\fItextfile2\fR\fR\fB \&.\&.\&.]\fR
.fi
.if n \{\
.RE
.\}
.PP
For each text file named on the command line,
\fBmysqlimport\fR
strips any extension from the file name and uses the result to determine the name of the table into which to import the file\'s contents\&. For example, files named
patient\&.txt,
patient\&.text, and
patient
all would be imported into a table named
patient\&.
.PP
\fBmysqlimport\fR
supports the options in the following list\&. It also reads option files and supports the options for processing them described at
Section\ \&4.2.3.3.1, \(lqCommand-Line Options that Affect Option-File Handling\(rq\&.

\fB\-\-replace\fR, new rows replace existing rows that have the same unique key value\&. If you specify
\fB\-\-ignore\fR, input rows that duplicate an existing row on a unique key value are skipped\&. If you do not specify either option, an error occurs when a duplicate key value is found, and the rest of the text file is ignored\&.
