<p>
Jackcess is a pure Java library for reading from and writing to MS
Access databases (currently supporting versions 2000-2010). 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.apache.org/licenses/LICENSE-2.0.txt">Apache License</a> (as of version 2.1.0).
Take a look
at our <a href="faq.html">Frequently Asked Questions</a>
for more info.
</p>
<subsection name="Brand New License!">
<p>
Due to the generosity of Health Market Science and the efforts of
the <a href="https://tika.apache.org/">Apache Tika project</a>, the
OpenHMS projects have been relicensed under the <b>Apache License,
Version 2.0</b> (Jackcess versions 2.1.0 and higher).
</p>
</subsection>
<subsection name="All New: Jackcess 2.0">
<p>
<b>New crunchy outside, same yummy filling!</b>
</p>
<p>
The Jackcess project has gotten a facelift. A long-overdue overhaul
of the public API has been completed, and the major version number
of the Jackess APi has been changed to 2.0 in order to indicate the
non-backwards compatible nature of the changes (although the
underlying functionality remains unchanged). Read the
<a href="jackcess-2.html">Upgrade Guide</a> for full details.

<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>Iterating through the rows of a table:
<source>Table table = DatabaseBuilder.open(new File("my.mdb")).getTable("MyTable");
for(Row 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>Row row = CursorBuilder.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 = DatabaseBuilder.create(Database.FileFormat.V2000, new File("new.mdb"));
Table newTable = new TableBuilder("NewTable")
.addColumn(new ColumnBuilder("a")
.setSQLType(Types.INTEGER))
.addColumn(new ColumnBuilder("b")
.setSQLType(Types.VARCHAR))
.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 db = DatabaseBuilder.open(new File("my.mdb"));
new ImportUtil.Builder(db, "Imported").importResultSet(resultSet);
db.close();</source>
</li>
<li>Copying the contents of a CSV file into a new table:
<source>Database db = DatabaseBuilder.open(new File("my.mdb"));
new ImportUtil.Builder(db, "Imported2").setDelimiter(",").importFile(new File("my.csv"));
db.close();</source>
</li>
</ul>
