  7. <h2><a name="sql">Sql</a></h2>
  8. <h3>Description</h3>
  9. <p>Executes a series of SQL statements via JDBC to a database. Statements can
  10. either be read in from a text file using the <i>src</i> attribute or from
  11. between the enclosing SQL tags.</p>
  12. <p>Multiple statements can be provided, separated by semicolons (or the
  13. defined <i>delimiter</i>). Individual lines within the statements can be
  14. commented using either --, // or REM at the start of the line.</p>
  15. <p>The <i>autocommit</i> attribute specifies whether auto-commit should be
  16. turned on or off whilst executing the statements. If auto-commit is turned
  17. on each statement will be executed and committed. If it is turned off the
  18. statements will all be executed as one transaction.</p>
  19. <p>The <i>onerror</i> attribute specifies how to proceed when an error occurs
  20. during the execution of one of the statements.
  21. The possible values are: <b>continue</b> execution, only show the error;
  22. <b>stop</b> execution and commit transaction;
  23. and <b>abort</b> execution and transaction and fail task.</p>

  107. <h3>Parameters specified as nested elements</h3>
  108. <h4>transaction</h4>
  109. <p>Use nested <code>&lt;transaction&gt;</code>
  110. elements to specify multiple blocks of commands to the executed
  111. executed in the same connection but different transactions. This
  112. is particularly useful when there are multiple files to execute
  113. on the same schema.</p>

  125. </table>
  126. <h4>fileset</h4>
  127. <p>You can specify multiple source files via nested <a
  128. href="../CoreTypes/fileset.html">fileset</a> elements. Each file of
  129. the fileset will be run in a transaction of its own, the order by
  130. which the files of a single fileset will be executed is not
  131. defined.</p>
  132. <h4>classpath</h4>
  133. <p><code>Sql</code>'s <em>classpath</em> attribute is a <a
  134. href="../using.html#path">PATH like structure</a> and can also be set via a nested
  135. <em>classpath</em> element. It is used to load the JDBC classes.</p>

  139. <h3>Examples</h3>
  140. <blockquote><pre>&lt;sql
  141. driver=&quot;org.database.jdbcDriver&quot;
  142. url=&quot;jdbc:database-url&quot;
  143. userid=&quot;sa&quot;
  144. password=&quot;pass&quot;
  145. src=&quot;data.sql&quot;
  146. /&gt;
  147. </pre></blockquote>
  148. <p>Connects to the database given in <i>url</i> as the sa user using the
  149. org.database.jdbcDriver and executes the SQL statements contained within
  150. the file data.sql</p>
  151. <blockquote><pre>&lt;sql
  152. driver=&quot;org.database.jdbcDriver&quot;
  153. url=&quot;jdbc:database-url&quot;
  154. userid=&quot;sa&quot;
  155. password=&quot;pass&quot;
  156. &gt;
  157. insert
  158. into table some_table
  159. values(1,2,3,4);
  160. truncate table some_other_table;
  161. &lt;/sql&gt;
  162. </pre></blockquote>
  163. <p>Connects to the database given in <i>url</i> as the sa
  164. user using the org.database.jdbcDriver and executes the two SQL statements
  165. inserting data into some_table and truncating some_other_table </p>
  166. <p>Note that you may want to enclose your statements in
  167. <code>&lt;![CDATA[</code> ... <code>]]&gt;</code> sections so you don't
  168. need to escape <code>&lt;</code>, <code>&gt;</code> <code>&amp;</code>
  169. or other special characters. For example:</p>
  170. <blockquote><pre>&lt;sql
  171. driver=&quot;org.database.jdbcDriver&quot;
  172. url=&quot;jdbc:database-url&quot;
  173. userid=&quot;sa&quot;
  174. password=&quot;pass&quot;
  175. &gt;&lt;![CDATA[
  176. update some_table set column1 = column1 + 1 where column2 &lt; 42;
  177. ]]&gt;&lt;/sql&gt;
  178. </pre></blockquote>
  179. <p>The following connects to the database given in url as the sa user using
  180. the org.database.jdbcDriver and executes the SQL statements contained within
  181. the files data1.sql, data2.sql and data3.sql and then executes the truncate
  182. operation on <i>some_other_table</i>.</p>
  183. <blockquote><pre>&lt;sql
  184. driver=&quot;org.database.jdbcDriver&quot;
  185. url=&quot;jdbc:database-url&quot;
  186. userid=&quot;sa&quot;
  187. password=&quot;pass&quot; &gt;
  188. &lt;transaction src=&quot;data1.sql&quot; /&gt;
  189. &lt;transaction src=&quot;data2.sql&quot; /&gt;
  190. &lt;transaction src=&quot;data3.sql&quot; /&gt;
  191. &lt;transaction&gt;
  192. truncate table some_other_table;
  193. &lt;/transaction&gt;
  194. &lt;/sql&gt;
  195. </pre></blockquote>
  196. <p>The following example does the same as (and may execute additional
  197. SQL files if there are more files matching the pattern
  198. <code>data*.sql</code>) but doesn't guarantee that data1.sql will be
  199. run before <code>data2.sql</code>.</p>
  200. <blockquote><pre>&lt;sql

  209. truncate table some_other_table;
  210. &lt;/transaction&gt;
  211. &lt;/sql&gt;
  212. </pre></blockquote>
  213. <p>The following connects to the database given in url as the sa user using the
  214. org.database.jdbcDriver and executes the SQL statements contained within the
  215. file data.sql, with output piped to outputfile.txt, searching /some/jdbc.jar
  216. as well as the system classpath for the driver class.</p>
  217. <blockquote><pre>&lt;sql
  218. driver=&quot;org.database.jdbcDriver&quot;

  228. &lt;/classpath&gt;
  229. &lt;/sql&gt;
  230. </pre></blockquote>
  231. <p>The following will only execute if the RDBMS is &quot;oracle&quot; and the version
  232. starts with &quot;8.1.&quot;</p>
  233. <blockquote><pre>&lt;sql
