SqlDescriptionExecutes a series of SQL statements via JDBC to a database. 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. Parameters
Parameters specified as nested elementstransactionUse nested
filesetYou can specify multiple source files via nested fileset elements. Each file of the fileset will be run in a transaction of its own, the order by which the files of a single fileset will be executed is not defined. classpath
The Examples<sql driver="org.database.jdbcDriver" url="jdbc:database-url" userid="sa" password="pass" src="data.sql" /> 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 <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> Connects to the database given in url 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 Note that you may want to enclose your statements in
<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> 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 some_other_table. <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> The following example does the same as (and may execute additional
SQL files if there are more files matching the pattern
<sql driver="org.database.jdbcDriver" url="jdbc:database-url" userid="sa" password="pass"> <fileset dir="."> <include name="data*.sql"/> </fileset> <transaction> truncate table some_other_table; </transaction> </sql> 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. <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> The following will only execute if the RDBMS is "oracle" and the version starts with "8.1." <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> Copyright © 2000-2002 Apache Software Foundation.
