Class SQLExec

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

Method Detail

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

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.

addText

public void addText(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.

createTransaction

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

Returns: a Transaction to be configured.

execSQL

protected void execSQL(String sql, PrintStream out)
Exec the sql statement.

Parameters: sql the SQL statement to execute out the place to put output

Throws: SQLException on SQL problems

execute

public void execute()
Load the sql file and then execute it

Throws: BuildException on error.

getExpandProperties

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

Returns: true if properties are to be expanded.

Since: Ant 1.7

printResults

protected void printResults(PrintStream out)

Deprecated: since 1.6.x. Use the two arg version instead.

print any results in the statement

Parameters: out the place to print results

Throws: SQLException on SQL problems.

printResults

protected void printResults(ResultSet rs, PrintStream out)
print any results in the result set.

Parameters: rs the resultset to print information about out the place to print results

Throws: SQLException on SQL problems.

Since: Ant 1.6.3

runStatements

protected void runStatements(Reader reader, PrintStream out)
read in lines and execute them

Parameters: reader the reader contains sql lines. out the place to output results.

Throws: SQLException on sql problems IOException on io problems

setAppend

public void setAppend(boolean append)
whether output should be appended to or overwrite an existing file. Defaults to false.

Parameters: append if true append to an existing file.

Since: Ant 1.5

setDelimiter

public void setDelimiter(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.

Parameters: delimiter the separator.

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.

Parameters: delimiterType the type of delimiter - "normal" or "row".
