- All Implemented Interfaces:
    java.lang.Cloneable

      public class SQLExec
      extends JDBCTask

  Executes a series of SQL statements on a database using JDBC.

  Statements can either be read in from a text file using the src attribute or from between the enclosing SQL tags.

  Multiple statements can be provided, separated by semicolons (or the defined delimiter). Individual lines within the statements can be commented using either --, // or REM at the start of the line.

  The autocommit 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.

  The onerror attribute specifies how to proceed when an error occurs during the execution of one of the statements. The possible values are: continue execution, only show the error; stop execution and commit transaction; and abort execution and transaction and fail task.

  Since:
    Ant 1.2
