| <h2><a name="sql">Sql</a></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 <i>src</i> attribute or from |
| between the enclosing SQL tags.</p> |
| |
| <p>Multiple statements can be provided, separated by semicolons (or the |
| defined <i>delimiter</i>). Individual lines within the statements can be |
| commented using either --, // or REM at the start of the line.</p> |
| |
| <p>The <i>autocommit</i> attribute specifies whether auto-commit should be |
| turned on or off whilst executing the statements. If auto-commit is turned |
| on each statement will be executed and committed. If it is turned off the |
| statements will all be executed as one transaction.</p> |
| |
| <p>The <i>onerror</i> attribute specifies how to proceed when an error occurs |
| during the execution of one of the statements. |
| The possible values are: <b>continue</b> execution, only show the error; |
| <b>stop</b> execution and commit transaction; |
| and <b>abort</b> execution and transaction and fail task.</p> |
| |
| <p> |
| <b>Proxies</b>. Some JDBC drivers (including the Oracle thin driver), |
| use the JVM's proxy settings to route their JDBC operations to the database. |
| Since Ant1.7, Ant running on Java1.5 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 <code>-noproxy</code> option. |

| <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 border="1" cellpadding="2" cellspacing="0"> |
| <tr> |
| <td valign="top"><b>Attribute</b></td> |
| <td valign="top"><b>Description</b></td> |
| <td align="center" valign="top"><b>Required</b></td> |
| </tr> |
| <tr> |
| <td valign="top">src</td> |
| <td valign="top">File containing SQL statements</td> |
| <td valign="top" align="center">Yes, unless statements enclosed within tags</td> |
| </tr> |
| </table> |
| <p>The <code><transaction></code> element supports any <a |
| href="../CoreTypes/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="../CoreTypes/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> |
| |
| <h3>Examples</h3> |
| <blockquote><pre><sql |
| driver="org.database.jdbcDriver" |
| url="jdbc:database-url" |
| userid="sa" |
| password="pass" |
| src="data.sql" |
| /> |
| </pre></blockquote> |
| |
| <p>Connects to the database given in <i>url</i> as the sa user using the |
| org.database.jdbcDriver and executes the SQL statements contained within |
| the file data.sql</p> |
| |
| <blockquote><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></blockquote> |
| |
| <p>Connects to the database given in <i>url</i> as the sa |
| user using the org.database.jdbcDriver and executes the two SQL statements |
| inserting data into some_table and truncating some_other_table. Ant Properties |
| in the nested text will not be expanded.</p> |
| |
| <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> |
| |
| <blockquote><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></blockquote> |
| |
| 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. |
| |
| <blockquote><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></blockquote> |
| |
| |
| <p>The following connects to the database given in url as the sa user using |
| the org.database.jdbcDriver and executes the SQL statements contained within |
| the files data1.sql, data2.sql and data3.sql and then executes the truncate |
| operation on <i>some_other_table</i>.</p> |
| |
| <blockquote><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></blockquote> |
| |
| <p>The following example does the same as (and may execute additional |
| SQL files if there are more files matching the pattern |
| <code>data*.sql</code>) but doesn't guarantee that data1.sql will be |
| run before <code>data2.sql</code>.</p> |
| |
| <blockquote><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></blockquote> |
| |
| <p>The following connects to the database given in url as the sa user using the |
| org.database.jdbcDriver and executes the SQL statements contained within the |
| file data.sql, with output piped to outputfile.txt, searching /some/jdbc.jar |
| as well as the system classpath for the driver class.</p> |
| |
| <blockquote><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></blockquote> |
| |
| <p>The following will only execute if the RDBMS is "oracle" and the version |
| starts with "8.1."</p> |
| |
| <blockquote><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></blockquote> |
