<title>Using JDBC batch operations</title>

<h3>JDBC batch operations</h3>
<p>
With JDBC, you can easily execute several statements at once using the addBatch() method. Essentially, there are two modes in JDBC
</p>
<ul>
<li>Execute several queries without bind values</li>
<li>Execute one query several times with bind values</li>
</ul>
<p>
In code, this looks like the following snippet:
</p>
<java><![CDATA[// 1. several queries
// ------------------
Statement stmt = connection.createStatement();
stmt.addBatch("INSERT INTO author VALUES (1, 'Erich Gamma')");
stmt.addBatch("INSERT INTO author VALUES (2, 'Richard Helm')");
stmt.addBatch("INSERT INTO author VALUES (3, 'Ralph Johnson')");
stmt.addBatch("INSERT INTO author VALUES (4, 'John Vlissides')");
int[] result = stmt.executeBatch();
// 2. a single query
// -----------------
PreparedStatement stmt = connection.prepareStatement("INSERT INTO autho VALUES (?, ?)");
stmt.setInt(1, 1);
stmt.setString(2, "Erich Gamma");
stmt.addBatch();
stmt.setInt(1, 2);
stmt.setString(2, "Richard Helm");
stmt.addBatch();
stmt.setInt(1, 3);
stmt.setString(2, "Ralph Johnson");
stmt.addBatch();
stmt.setInt(1, 4);
stmt.setString(2, "John Vlissides");
stmt.addBatch();
int[] result = stmt.executeBatch();]]></java>
<h3>This will also be supported by jOOQ</h3>
<p>
jOOQ supports executing queries in batch mode as follows:
</p>
<java><![CDATA[// 1. several queries
// ------------------
create.batch(
create.insertInto(AUTHOR, ID, NAME).values(1, "Erich Gamma"),
create.insertInto(AUTHOR, ID, NAME).values(2, "Richard Helm"),
create.insertInto(AUTHOR, ID, NAME).values(3, "Ralph Johnson"),
create.insertInto(AUTHOR, ID, NAME).values(4, "John Vlissides"))
.execute();
// 2. a single query
// -----------------
create.batch(create.insertInto(AUTHOR, ID, NAME).values("?", "?"))
.bind(1, "Erich Gamma")
.bind(2, "Richard Helm")
.bind(3, "Ralph Johnson")
.bind(4, "John Vlissides")
.execute();]]></java>
