NAME
Win32::SqlServer::DTS::Package - a Perl class to access Microsoft SQL Server 2000 DTS Packages
SYNOPSIS
use Win32::SqlServer::DTS::Package;
# $OLE_package is an already instantied class using Win32::OLE
my $package = Win32::SqlServer::DTS::Package->new( $OLE_package );
# prints the custom task name
print $custom_task->get_name, "\n";
DESCRIPTION
Win32::SqlServer::DTS::Package
is an class created to be used as a layer that represent a package object in DTS packages.
EXPORT
Nothing.
METHODS
execute
Execute all the steps available in the package.
Requires that the _sibling
attribute exists and is defined correctly, otherwise method call will abort program execution.get_connections
Returns a array reference with Win32::SqlServer::DTS::Package::Step::Result
objects for error checking.
get_steps
Returns an iterator to get all steps defined inside the DTS package. Each call to the iterator (that is a code reference) will return a Win32::SqlServer::DTS::Package::Step
object until all steps are returned.
log_to_server
Returns true or false (in Perl terms, this means 1 or 0 respectivally) if the "Log package execution to SQL Server" is set.
auto_commit
Returns true or false (in Perl terms, this means 1 or 0 respectivally) if the "Auto Commit Transaction property" is set.
new
Expects a DTS.Package2 object as a parameter and returns a new Win32::SqlServer::DTS::Package
object.
Not all properties from a DTS.Package2 will be available, specially the inner objects inside a DTS package will be available only at execution of the respective methods. These methods may depend on the _sibling
attribute, so one should not remove it before invoking those methods. The documentation tells where the method depends or not on _sibling
attribute.
use_explicit_global_vars
Returns true if the property "Explicit Global Variables" is set. Otherwise returns false.
use_event_log
Returns true if the property "Write completation status to event log" is set. Otherwise returns false.
fail_on_error
Returns true if the property "Fail package on first error" is set. Otherwise returns false.
add_lineage_vars
Returns true or false (1 or 0 respectivally) if the Add Lineage Variables property is set.
is_lineage_none
Returns true if provide no lineage (default) or false otherwise.
is_repository
Returns true or false if the package will write to Meta Data Services if available.
is_repository_required
Returns true or false if writing to Meta Data Services is required.
to_string
Returns a string will all properties from the package, separated with new line characters. Each property also has a text with a sort description of the property.
This method will not fetch automatically the properties from objects inside the package, line connections and tasks. Each object must be fetched first using the apropriated method and them invoking the to_string
from each object.
get_connections
Returns an iterator (code reference) that will return a Win32::SqlServer::DTS::Connection
object at each invocation until there are no more objects available.
This method depends on having the _sibling
attribute available, therefore is not possible to invoke this method after invoking the kill_sibling
method.
count_connections
Returns an integer that represents the total amount of connections available in the package object.
Besides the convenience, this method is uses less resources than invoking the respective get_
method and looping over the references in the array reference.
This method depends on having the _sibling
attribute available, therefore is not possible to invoke this method after invoking the kill_sibling
method.
get_tasks
Returns an iterator. At each iterator (which is a code reference) call, one subclass object of Win32::SqlServer::DTS::Task
will be returned.
This method depends on having the _sibling
attribute available, therefore is not possible to invoke this method after invoking the kill_sibling
method.
Warning: get_tasks
method will abort with an error message if the DTS package has tasks that are not available as subclasses of Win32::SqlServer::DTS::Task
class. In doubt, use the available methods to fetch only the supported tasks. This should be "fixed" in future releases with the implementation of the missing classes.
count_tasks
Returns a integer with the number of tasks available inside the package.
Besides the convenience, this method is uses less resources than invoking the respective get_
method and looping over the references in the array reference.
This method depends on having the _sibling
attribute available, therefore is not possible to invoke this method after invoking the kill_sibling
method.
_get_tasks_by_type
_get_tasks_by_type
is a "private method". It will return an iterator (which is a code reference) that will return Win32::SqlServer::DTS::Task
subclasses objects at each call depending on the type passed as a parameter. It will not return and will complete ignore any Task class that is not returned by Win32::SqlServer::DTS::TaskTypes::get_types()
.
This method creates a cache after first call, so don't expect it will find new tasks after first invocation.
count_datapumps
Returns an integer represents the total amount of DataPumpTask
tasks available in the package.
Besides the convenience, this method is uses less resources than invoking the respective get_
method and looping over the references in the array reference.
This method depends on having the _sibling
attribute available, therefore is not possible to invoke this method after invoking the kill_sibling
method.
get_datapumps
Returns a iterator (code reference) that will return, at each invocation, a the DataPumpTasks
tasks available in the package.
This method depends on having the _sibling
attribute available, therefore is not possible to invoke this method after invoking the kill_sibling
method.
count_dynamic_props
Returns an integer represents the total amount of DynamicPropertiesTask
tasks available in the package.
Besides the convenience, this method is uses less resources than invoking the respective get_
method and looping over the references in the array reference.
This method depends on having the _sibling
attribute available, therefore is not possible to invoke this method after invoking the kill_sibling
method.
get_dynamic_props
Returns a iterator (code reference) that will return a Win32::SqlServer::DTS::Task::DynamicProperty
object at each invocation until there is no more tasks to return.
This method depends on having the _sibling
attribute available, therefore is not possible to invoke this method after invoking the kill_sibling
method.
get_execute_pkgs
Returns a iterator (code reference) that will return a Win32::SqlServer::DTS::Task::ExecutePackage
object at each invocation until there is no more tasks to return.
This method depends on having the _sibling
attribute available, therefore is not possible to invoke this method after invoking the kill_sibling
method.
count_execute_pkgs
Returns an integer with the total of ExecutePackageTask
tasks available in the package.
Besides the convenience, this method is uses less resources than invoking the respective get_
method and looping over the references in the array reference.
This method depends on having the _sibling
attribute available, therefore is not possible to invoke this method after invoking the kill_sibling
method.
get_send_emails
Returns an iterator (code reference) that will return a Win32::SqlServer::DTS::Task::SendEmail
at each invocation until there is no more tasks available.
This method depends on having the _sibling
attribute available, therefore is not possible to invoke this method after invoking the kill_sibling
method.
count_send_emails
Returns an integer with the total of SendMailTask
tasks available in the package.
Besides the convenience, this method is uses less resources than invoking the respective get_
method and looping over the references in the array reference.
This method depends on having the _sibling
attribute available, therefore is not possible to invoke this method after invoking the kill_sibling
method.
save_to_server
Saves the package to a SQL Server. This method must be called if the Win32::SqlServer::DTS::Package was modified (or it's inner object were).
Expectes a Win32::SqlServer::DTS::Credential object as a parameter. If the Package will be saved in the same server from where it was fetched it's useful to use the method get_credential
from the Win32::SqlServer::DTS::Application object.
The optional parameters:
PackageOwnerPassword
PackageOperatorPassword
PackageCategoryID
pVarPersistStgOfHost
bReusePasswords
from the original DTS API are not implemented.
save_to_file
Saves the package to a structured file.
Expects a complete pathname as a parameter. If a DTS structure filename is not passed together with the path, the method will use the package name followed by a '.dts' extension.
The optional parameters:
OwnerPassword
OperatorPassword
pVarPersistStgOfHost
bReusePasswords
from the original DTS API are not implemented.
get_creation_date
Returns a DataTime object with the timestamp of the creation date of the package. When used the to_string
method, it will be returned the equivalent result of the method datetime
from DateTime class.
The timezone of the DateTime object is the float one. See DateTime for more information.
get_creator_computer
Returns a string with the machine name from where the package was created.
get_description
Returns a string with the description of the package.
get_log_file
Returns a string with the filename of the file used to store the log messages from the package execution.
get_max_steps
Returns a integer the maximum number of steps allowed to be executed simultaneously in the package.
get_name
Returns a string with the name of the package
get_id
Returns a string with the unique ID in the database of the package.
get_priority
Returns a string with the priority of the package ('High', 'Low' or 'Normal').
get_version_id
Returns a string with the version ID of the package.
CAVEATS
This API is incomplete. There are much more properties defined in the SQL Server API.
