<title>SQL Task</title>
</head>
<body>
<h2 id="sql">Sql</h2>
<h3>Description</h3>
<p>Executes a series of SQL statements via JDBC to a database. Statements can either be read in from
a text file using the <var>src</var> attribute or from between the enclosing SQL tags.</p>
<p>Multiple statements can be provided, separated by semicolons (or the
defined <var>delimiter</var>). Individual lines within the statements can be commented using
either <q>--</q>, <q>//</q> or <q>REM</q> at the start of the line.</p>
<p>The <var>autocommit</var> attribute specifies whether auto-commit should be turned on or off
whilst executing the statements. If auto-commit is turned <q>on</q> each statement will be executed
and committed. If it is turned <q>off</q> the statements will all be executed as one
transaction.</p>
<p>The <var>onerror</var> attribute specifies how to proceed when an error occurs during the
execution of one of the statements. The possible values are: <q>continue</q> execution, only show
the error; <q>stop</q> execution, log the error but don't fail the task and <q>abort</q> execution
and transaction and fail task.</p>
<p><strong>Proxies</strong>. Some JDBC drivers (including the Oracle thin driver), use the JVM's
proxy settings to route their JDBC operations to the database. <em>Since Apache Ant 1.7</em>, Ant
running on Java 5 or later defaults to <a href="../proxy.html">using the proxy settings of the
operating system</a>. Accordingly, the OS proxy settings need to be valid, or Ant's proxy support
disabled with <kbd>-noproxy</kbd> option.</p>

<h3>Parameters specified as nested elements</h3>
<h4>transaction</h4>
<p>Use nested <code><transaction></code> elements to specify multiple blocks of commands to
the executed executed in the same connection but different transactions. This is particularly useful
when there are multiple files to execute on the same schema.</p>
<table class="attr">
<tr>
<th scope="col">Attribute</th>
<th scope="col">Description</th>
<th scope="col">Required</th>
</tr>
<tr>
<td>src</td>
<td>File containing SQL statements</td>
<td>Yes, unless statements enclosed within tags</td>
</tr>
</table>
<p>The <code><transaction></code> element supports
any <a href="../Types/resources.html">resource</a> or single element resource collection as nested
element to specify the resource containing the SQL statements.</p>
<h4>any <a href="../Types/resources.html">resource</a> or resource collection</h4>
<p>You can specify multiple sources via nested resource collection elements. Each resource of the
collection will be run in a transaction of its own. Prior to Ant 1.7 only filesets were supported.
Use a sort resource collection to get a predictable order of transactions.</p>
<h4>classpath</h4>
<p><code>Sql</code>'s <em>classpath</em> attribute is a <a href="../using.html#path">path-like
structure</a> and can also be set via a nested <em>classpath</em> element. It is used to load the
JDBC classes.</p>
<h4>connectionProperty</h4>
<p><em>Since Ant 1.8.0</em></p>
<p>Use nested <code><connectionProperty></code> elements to specify additional JDBC properties
that need to be set when connecting to the database.</p>
<table class="attr">
<tr>
<th scope="col">Attribute</th>
<th scope="col">Description</th>
<th scope="col">Required</th>
</tr>
<tr>
<td>name</td>
<td>Name of the property</td>
<td>Yes</td>
</tr>
<tr>
<td>value</td>
<td>Value of the property</td>
<td>Yes</td>
</tr>
</table>
<h3>Examples</h3>
<p>Connect to the database given in <var>url</var> as the <q>sa</q> user using
the <code>org.database.jdbcDriver</code> and execute the SQL statements contained within the
file <samp>data.sql</samp></p>
<pre>
<sql driver="org.database.jdbcDriver"
url="jdbc:database-url"
userid="sa"
password="pass"
src="data.sql"/></pre>
<p>Connect to the database given in <var>url</var> as the <q>sa</q> user using
the <code>org.database.jdbcDriver</code> and execute the SQL statements contained within the
file <samp>data.sql</samp>. Also set the property <code>internal_logon</code> to the
value <q>SYSDBA</q>.</p>
<pre>
<sql driver="org.database.jdbcDriver"
url="jdbc:database-url"
userid="sa"
password="pass"
src="data.sql">
<connectionProperty name="internal_logon" value="SYSDBA">
</sql></pre>
<p>Connect to the database given in <var>url</var> as the <q>sa</q> user using
the <code>org.database.jdbcDriver</code> and execute the two SQL statements inserting data
into <samp>some_table</samp> and truncating <samp>some_other_table</samp>. Ant properties in the
nested text will not be expanded.</p>
<pre>
<sql driver="org.database.jdbcDriver"
url="jdbc:database-url"
userid="sa"
password="pass">
insert
into table some_table
values(1,2,3,4);
truncate table some_other_table;
</sql></pre>
<p>Note that you may want to enclose your statements in <code><![CDATA[</code>
... <code>]]></code> sections so you don't need to
escape <code><</code>, <code>></code>, <code>&</code> or other special characters. For
example:</p>
<pre>
<sql driver="org.database.jdbcDriver"
url="jdbc:database-url"
userid="sa"
password="pass"><![CDATA[
update some_table set column1 = column1 + 1 where column2 < 42;
]]></sql></pre>
<p>The following command turns property expansion in nested text on (it is off purely for backwards
compatibility), then creates a new user in the HSQLDB database using Ant properties.</p>
<pre>
<sql driver="org.hsqldb.jdbcDriver";
url="jdbc:hsqldb:file:${database.dir}"
userid="sa"
password=""
expandProperties="true">
<transaction>
CREATE USER ${newuser} PASSWORD ${newpassword}
</transaction>
</sql></pre>
<p>The following connects to the database given in <var>url</var> as the <q>sa</q> user using
the <code>org.database.jdbcDriver</code> and executes the SQL statements contained within the
files <samp>data1.sql</samp>, <samp>data2.sql</samp> and <samp>data3.sql</samp> and then executes
the truncate operation on <samp>some_other_table</samp>.</p>
<pre>
<sql driver="org.database.jdbcDriver"
url="jdbc:database-url"
userid="sa"
password="pass">
<transaction src="data1.sql"/>
<transaction src="data2.sql"/>
<transaction src="data3.sql"/>
<transaction>
truncate table some_other_table;
</transaction>
</sql></pre>
<p>The following example does the same as (and may execute additional SQL files if there are more
files matching the pattern <samp>data*.sql</samp>) but doesn't guarantee that <samp>data1.sql</samp>
will be run before <samp>data2.sql</samp>.</p>
<pre>
<sql driver="org.database.jdbcDriver"
url="jdbc:database-url"
userid="sa"
password="pass">
<path>
<fileset dir=".">
<include name="data*.sql"/>
</fileset>
</path>
<transaction>
truncate table some_other_table;
</transaction>
</sql></pre>
<p>The following connects to the database given in <var>url</var> as the <q>sa</q> user using
the <code>org.database.jdbcDriver</code> and executes the SQL statements contained within the
file <samp>data.sql</samp>, with output piped to <samp>outputfile.txt</samp>,
searching <samp>/some/jdbc.jar</samp> as well as the system classpath for the driver class.</p>
<pre>
<sql driver="org.database.jdbcDriver"
url="jdbc:database-url"
userid="sa"
password="pass"
src="data.sql"
print="yes"
output="outputfile.txt">
<classpath>
<pathelement location="/some/jdbc.jar"/>
</classpath>
</sql></pre>
<p>The following will only execute if the RDBMS is <q>oracle</q> and the version starts
with <q>8.1.</q></p>
<pre>
<sql driver="org.database.jdbcDriver"
url="jdbc:database-url"
userid="sa"
password="pass"
src="data.sql"
rdbms="oracle"
version="8.1.">
insert
into table some_table
values(1,2,3,4);
truncate table some_other_table;
</sql></pre>
