<p>
Jackcess is a pure Java library for reading from and writing to MS
Access databases (currently supporting versions 2000-2007). It is part of the <a href="http://openhms.sourceforge.net/">OpenHMS</a> project from <a href="http://www.healthmarketscience.com/">Health Market Science, Inc.</a>. It is not an application. There is no GUI. It's a
library, intended for other developers to use to build Java
applications. Jackcess is licensed under the
<a href="http://www.gnu.org/licenses/old-licenses/lgpl-2.1.txt">GNU Lesser General Public License</a>.
Take a look
at our <a href="faq.html">Frequently Asked Questions</a>
for more info.

<section name="Sample code">
<p>
Here are a few snippets of code to whet your appetite. For more
extensive examples, checkout the <a href="cookbook.html">cookbook</a>. And, since Jackcess is heavily
unit tested, you can find even more example code in the <a href="xref-test/index.html">unit tests</a>.
</p>
<ul>
<li>Displaying the contents of a table:
<source>System.out.println(Database.open(new File("my.mdb")).getTable("MyTable").display());
</source>
</li>
<li>Iterating through the rows of a table:
<source>Table table = Database.open(new File("my.mdb")).getTable("MyTable");
for(Map<String, Object> row : table) {
System.out.println("Column 'a' has value: " + row.get("a"));
}
</source>
</li>
<li>Searching for a row with a specific column value:
<source>Map<String, Object> row = Cursor.findRow(table, Collections.singletonMap("a", "foo"));
if(row != null) {
System.out.println("Found row where 'a' == 'foo': " + row);
} else {
System.out.println("Could not find row where 'a' == 'foo'");
}
</source>
</li>
<li>Creating a new table and writing data into it:
<source>Database db = Database.create(new File("new.mdb"));
Table newTable = new TableBuilder("NewTable")
.addColumn(new ColumnBuilder("a")
.setSQLType(Types.INTEGER)
.toColumn())
.addColumn(new ColumnBuilder("b")
.setSQLType(Types.VARCHAR)
.toColumn())
.toTable(db);
newTable.addRow(1, "foo");
</source>
</li>
<li>Copying the contents of a JDBC ResultSet (e.g. from an
external database) into a new table:
<source>Database.open(new File("my.mdb")).copyTable("Imported", resultSet);</source>
</li>
<li>Copying the contents of a CSV file into a new table:
<source>Database.open(new File("my.mdb")).importFile("Imported2", new File("my.csv"), ",");</source>
</li>
</ul>
