Loading a Flat File to a MySQL Table</h3>
The default format of a file to load into a MySQL table is as follows:
the fields must be separated by tabs, the input lines terminated by
'\n', and backslashes(\), newlines (\n), and tabs (\t) escaped by a
backslash. The MySQL documentation explains how to change these
defaults.
<P> This example loads a flat file called <code>infile.txt</code> to a MySQL
table named <code>mysql_2_table</code> with an INT and a VARCHAR(20) column.
<pre>
try {
// Create the statement
Statement stmt = <font color="#0066ff"><i>connection</i></font>.createStatement();
// Load the data
String filename = <font color="#0066ff"><i>"c:\\\\temp\\\\infile.txt"</i></font>;
String tablename = <font color="#0066ff"><i>"mysql_2_table"</i></font>;
stmt.executeUpdate("LOAD DATA INFILE \"" + filename + "\" INTO TABLE " + tablename);
// If the file is comma-separated, use this statement
stmt.executeUpdate("LOAD DATA INFILE \"" + filename + "\" INTO TABLE "
+ tablename + " FIELDS TERMINATED BY ','");
// If the file is terminated by \r\n, use this statement
stmt.executeUpdate("LOAD DATA INFILE \"" + filename + "\" INTO TABLE "
+ tablename + " LINES TERMINATED BY '\\r\\n'");
} catch (SQLException e) {
}
</pre>
An example of the contents of infile.txt
(\t represents an invisible tab character):
<pre>
123\tString1
234\tString2
