Data Service Block: Repeat for All Rows

In a business rule designed in the Configurator, you can add a Repeat for All Rows component block to perform actions in relation to each row in the result of a query of a JDBC data service. You can specify a list of component blocks to be run each time a row is processed.

Tip: Before you can add a component block to a business rule, you must create a component set by specifying a trigger that controls when component blocks in the component set are run.

Property	Description
Data Service	The fully-qualified path to an existing data service in Loftware Enterprise SP. Tip: You can use the Relative Path check box to control whether the path is represented as an absolute path or a relative path. Using a relative path may be helpful if an object is likely to be transferred to a different Loftware Enterprise SP instance A Loftware Application Server and a Loftware Database Server that are associated with each other by a Loftware Enterprise - SP License.. The check box is available to select after the object has been saved for the first time. For more information, see Relative Paths.
Use Parameters?	Whether to add parameters for use in the data service. Note: This functionality is comparable to editing the data service in Data Services and adding parameters. However, the parameters exist only when this business rule is used to run the data service. Tip: You can use a parameter to define the query to be run by the data service. Tip: You can add or remove parameters by clicking or .
Parameter Name	The name (key) of a parameter that can be used in the data service defined in Data Services . For a list of built-in parameters, see the section following this table.
Parameter Value	A print job property or the name of a data map entry to be used in the data service. Also, whether to interpret it as a literal value or as a data map entry. If the data map entry does not already exist, it is created. You can select from the following for a data ref. Manually Entered A property that allows a Designer or administrator to type in the value for a property rather than select it from a list. For a data ref, value must be the fully-qualified name of a data map entry. Job Detail Name A digital representation of a label generated by a print job. Job details can be altered during the print job by using Formula data sources, Script data sources, and business rules. Job Name What is submitted for processing. A job is separated into print jobs and print job details based on the processing rules. A job defines which processes to use. Label Template A digital representation of a label that can be combined with variable data and used by print jobs to generate print job details. Number of Duplicates The number of times to reprint a label by using the same data and without changing the value in any incrementing or decrementing field. Each duplicate printed label is identical. Pages of Labels The number of times to print the content for the labels in a layout. Each page is identical, including the value in any incrementing or decrementing field. Printer A physical printer, print queue, or other target for output, such as an image file or a PDF file. Printer Tray To which output tray to direct printed labels or documents. If a printer has only one output tray or otherwise does not support this feature, this is ignored. For Windows drivers the tray is the name of the tray that supplies the paper. The name corresponds to the configured tray name in the driver setup (not case sensitive). For PCL 5e drivers the tray is the ID number of the tray that supplies the paper. The ID corresponds to the configured tray number in the driver setup. Quantity of Labels The number of times to print a label by using the same data. Each printed label produced is identical except for any incrementing or decrementing field.
Rule Action	The list of component blocks to be run when a row returned by the data service is processed. You can add a component block by dragging it from the Insert tab dropping it onto a Drop block here marker within this component block.

The following built-in parameters exist for an HTTP data service A connection to plain text data or image data that is external to Loftware. A File data service or an HTTP data service drives Alternate data sources used in documents.. The accepted values for a parameter or whether the parameter is valid may vary depending on whether the value of fileRequestMethod is GET or POST.

Parameter	Description

SOAP Web Service Data Service Parameters

The following built-in parameters exist for a SOAP Web Service data service.

Parameter	Description
ADD_JSON_TO_MAP	Whether to allow JSON data to be added to the data map. Tip: If you set this parameter to true, you can set ADD_XML_NODES_TO_MAP to false so that only JSON data is added to the data map.
ADD_RAW_XML_TO_MAP	Whether to allow raw XML data to be added to the data map. Tip: If you set this parameter to true, you can set ADD_XML_NODES_TO_MAP to false so that only raw XML data is added to the data map.
ADD_XML_NODES_TO_MAP	Whether to allow XML nodes to be added to the data map.
ADDRESS	Web Service Address. The link for connecting to a web service.
authType	Authentication Type. The authentication type for connecting to the web service. None: Do not require authentication. Basic: Require a user name and password to connect to the web service.
ENVELOPE	Envelope. The XML for the SOAP envelope element. This is the root element of a SOAP message and defines the XML document as a SOAP message.
HTTP_HEADERS	HTTP Headers. The names and values that define the operating parameters of the HTTP transaction.
password	Password. The password of the credentials to use when connecting to the web service.
RESULT_PATH	Result Path. The path to the subset of data that you want returned from the web service. If XPATH_OVERRIDE is true, this is the XPath expression of the subset of data that you want returned from the web service. For more information, see Example: Result Path and XPath Override below. If XPATH_OVERRIDE is false, this value is not used.
resultMap	Result Name. The name of the XML Data business rule component to be used. The default name is WS_RESULT.
SECURITY_HEADER	Security Header. A security header that provides credentials for connecting to the web service.
username	User Name. The user name of the credentials to use when connecting to the web service.
WSDL_URL	WSDL URL. The link to a Web Services Description Language (WSDL) that you can use to communicate with a web service. A WSDL is an XML-based language for defining an interface. A WSDL describes how a service can be called, what arguments can be used, and what type of data is expected to be returned.
XPATH_OVERRIDE	XPath Override. Whether to define the subset of data that you want returned from the web service by the XPath expression entered as the Result Path. For more information, see the example that follows. true: The value of RESULT_PATH is the XPath expression of the subset of data that you want returned from the web service. false: The entire data set is returned.

Example: Result Path and XPath Override

If the configuration of the web service in Data Services contains the following values:

Result Path	/getCountryResponse/country
XPath Override

Result Path	/[local-name()='Envelope']/[local-name()='Body']/[local-name()='getCountryResponse']/[local-name()='country']
XPath Override

and the SOAP response from the web service is the following:

<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">

<SOAP-ENV:Header/>

<SOAP-ENV:Body>

<ns2:getCountryResponse xmlns:ns2="http://spring.io/guides/gs-producing-web-service">

<ns2:country>

<ns2:name>Spain</ns2:name>

<ns2:population>46704314</ns2:population>

<ns2:capital>Madrid</ns2:capital>

<ns2:currency>EUR</ns2:currency>

</ns2:country>

</ns2:getCountryResponse>

</SOAP-ENV:Body>

</SOAP-ENV:Envelope>

Then the following data map entries result:

/Body/name/!TEXT! Spain

/Body/population/!TEXT! 46704314

/Body/capital/!TEXT! Madrid

/Body/currency/!TEXT! EUR
