  20. </head>
  21. <body>
  22. <h2><a name="sql">Sql</a></h2>
  23. <h3>Description</h3>
  24. <p>Executes a series of SQL statements via JDBC to a database. Statements can
  25. either be read in from a text file using the <i>src</i> attribute or from
  26. between the enclosing SQL tags.</p>
  27. <p>Multiple statements can be provided, separated by semicolons (or the
  28. defined <i>delimiter</i>). Individual lines within the statements can be
  29. commented using either --, // or REM at the start of the line.</p>
  30. <p>The <i>autocommit</i> attribute specifies whether auto-commit should be
  31. turned on or off whilst executing the statements. If auto-commit is turned
  32. on each statement will be executed and committed. If it is turned off the
  33. statements will all be executed as one transaction.</p>
  34. <p>The <i>onerror</i> attribute specifies how to proceed when an error occurs
  35. during the execution of one of the statements.
  36. The possible values are: <b>continue</b> execution, only show the error;
  37. <b>stop</b> execution, log the error but don't fail the task
  38. and <b>abort</b> execution and transaction and fail task.</p>
  39. <p>
  40. <b>Proxies</b>. Some JDBC drivers (including the Oracle thin driver),
  41. use the JVM's proxy settings to route their JDBC operations to the database.
  42. Since Ant1.7, Ant running on Java1.5 or later defaults to
  43. <a href="../proxy.html">using
  44. the proxy settings of the operating system</a>.
  45. Accordingly, the OS proxy settings need to be valid, or Ant's proxy
  46. support disabled with <code>-noproxy</code> option.
  47. </p>

  369. The following command turns property expansion in nested text on (it is off purely for backwards
  370. compatibility), then creates a new user in the HSQLDB database using Ant properties.
  371. <blockquote><pre>&lt;sql

  383. <p>The following connects to the database given in url as the sa user using
  384. the org.database.jdbcDriver and executes the SQL statements contained within
  385. the files data1.sql, data2.sql and data3.sql and then executes the truncate
  386. operation on <i>some_other_table</i>.</p>

  400. <p>The following example does the same as (and may execute additional
  401. SQL files if there are more files matching the pattern
  402. <code>data*.sql</code>) but doesn't guarantee that data1.sql will be
