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

addText

public void addText(java.lang.String sql)

Set an inline SQL command to execute. NB: Properties are not expanded in this text.

addFileset

public void addFileset(FileSet set)

Adds a set of files (nested fileset attribute).

createTransaction

public SQLExec.Transaction createTransaction()

Add a SQL transaction to execute

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

For example, set this to "go" and delimitertype to "ROW" for Sybase ASE or MS SQL Server.

setDelimiterType

public void setDelimiterType(SQLExec.DelimiterType delimiterType)

Set the delimiter type: "normal" or "row" (default "normal").

The delimiter type takes two values - normal and row. Normal means that any occurrence of the delimiter terminate the SQL command whereas with row, only a line containing just the delimiter is recognized as the end of the command.

setPrint

public void setPrint(boolean print)

Print result sets from the statements; optional, default false

setShowheaders

public void setShowheaders(boolean showheaders)

Print headers for result sets from the statements; optional, default true.

setOutput

public void setOutput(java.io.File output)

Set the output file; optional, defaults to the Ant log.

setAppend

public void setAppend(boolean append)

whether output should be appended to or overwrite an existing file. Defaults to false.

Since:

Ant 1.5

setOnerror

public void setOnerror(SQLExec.OnError action)

Action to perform when statement fails: continue, stop, or abort optional; default "abort"

setKeepformat

public void setKeepformat(boolean keepformat)

whether or not format should be preserved. Defaults to false.

Parameters:

keepformat - The keepformat to set

setEscapeProcessing

public void setEscapeProcessing(boolean enable)

Set escape processing for statements.

Since:

Ant 1.6
