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

Constructor Detail

SQLExec

public SQLExec()
Method Detail

setSrc

public void setSrc(java.io.File srcFile)
Set the name of the SQL file to be run. Required unless statements are enclosed in the build file

Parameters:
srcFile - the file containing the SQL command.

setExpandProperties

public void setExpandProperties(boolean expandProperties)
Enable property expansion inside nested text

Parameters:
expandProperties - if true expand properties.
Since:
Ant 1.7

getExpandProperties

public boolean getExpandProperties()
is property expansion inside inline text enabled?

Returns:
true if properties are to be expanded.
Since:
Ant 1.7

addText

public void addText(java.lang.String sql)
Set an inline SQL command to execute. NB: Properties are not expanded in this text unless expandProperties is set.

Parameters:
sql - an inline string containing the SQL command.

addFileset

public void addFileset(FileSet set)
Adds a set of files (nested fileset attribute).

Parameters:
set - a set of files contains SQL commands, each File is run in a separate transaction.

add

public void add(ResourceCollection rc)
Adds a collection of resources (nested element).

Parameters:
rc - a collection of resources containing SQL commands, each resource is run in a separate transaction.
Since:
Ant 1.7

createTransaction

public SQLExec.Transaction createTransaction()
Add a SQL transaction to execute

Returns:
a Transaction to be configured.

setEncoding

public void setEncoding(java.lang.String encoding)
Set the file encoding to use on the SQL files read in

Parameters:
encoding - the encoding to use on the files

setDelimiter

public void setDelimiter(java.lang.String delimiter)
Set the delimiter that separates SQL statements. Defaults to ";"; optional

delimiter - the separator.

setDelimiterType
