Function

Description

Examples

ADDXML(String xml)

This function adds XML structure to the present element. This function is used when the source application doesn't expose their fields in their API then a user can map the field by modifying the XML structure to post back. This will add the XML on the root node of the target XML structure.

Mapping: <TargetField> = { ADDXML("<xml element>" + VALUE("sourcefield") +  "</xml element>");return "";}

Example: Database fields 
Trigger: select id,firstname from contact.

The above query fetches id, firstname from contact table of the database. The table also has a field of "contactaddress" and so query will not populate the "contactaddress" field in the target schema.

Name = {ADDXML("<address>" +VALUE("ContactAddress") + "</address>");return VALUE("Firstname");}

However i can map the source field and the populate the source field data in to contactaddress column of database and this contactaddress field is written to the target application

ADDXML(String xPath, String xml)

This function appends XML structure to the XPath passed. This function is used when the source application doesn't expose their fields through their API then a user can do the mapping for the field and parse the data

Let us take an example of custom field SalesRep__c  on Opportunity in Salesforce.

We have to map this field to SalesRep custom field on QuickBooks online.To map this field, type custom field name(SalesRep) in the target area(QuickBook online) and add below given query in the source field.

Mapping: <TargetField> = { ADDXML("<CustomField><DefinitionId>2</DefinitionId><Name>SalesRep</Name><Type>StringType</Type><StringValue>"+VALUE("SalesRep__c")+"</StringValue></CustomField>");

return "";

}

Where:
<DefinitionId>2</DefinitionId> :Position of custom field in QuickBooks online.

<Name>SalesRep</Name> : The custom field name in QuickBooks online.

  <StringValue>"+VALUE("SalesRep__c")+"</StringValue> : The custom field in Salesforce.

AND (boolean booleanExp1, boolean booleanExp2)

Mapping: <TargetField> = AND(booleanExp1,booleanExp2) 

Example : <TargetField> = AND(VALUE("Stage")=="Closed Won", VALUE("Type")=="Key Account") 

From the above example, The function returns true for all the records which are having "stage" as "Closed Won" and Type as "Key Account".

ASNUMBER(String value)

This function checks if a supplied value is a number and returns the actual number passed; else returns zero.

MAPPING: <TargetField> = ASNUMBER("String")

<TargetField> = ASNUMBER("123")

If the value for the number of employees is null or empty it will return zero. In this example, it will return 123 as a number.

CLEAN(String s1, String s2)

This function removes all non-printable characters from a supplied string value.

Mapping: <TargetField> = CLEAN("String VALUE")

Example: Salesforce object fields
Trigger: select Id, name from account

The above query will select Id and name from the account object of Salesforce. You can use the CLEAN() function to get the first character of the name field and set it to the target field.

<TargetField> = CLEAN (VALUE("Name"))

Mapping: <TargetField> = DATE(VALUE("source field"), "format string")

<TargetField> = DATE(VALUE("lasttransferdate"),"MM-DD-YYYY HH:MM:SS")
The value of lasttransferdate is Mar-12-2010 12:33:21, then the DATE() function will return value as 03-12-2010 12:33:21

This function reads a date string and returns the date string as per user specified date output format.

If the user specified date input format is not passed then it returns date string as "yyyyMMdd-HHmmssZ".

Mapping: <TargetField> = DATE(VALUE("source field"), "source format", "target format string")

<TargetField>= DATE(DATE(VALUE("createddate"),"yyyy-MM-ddhh:mm:ss"),"yyyy-MM-dd'T'HH:mm:ss'Z'")

The value of createddate is 03-12-2010 12:33:21, then the DATE() function will return value as 2010-12-03'T'12:33:21.

LINK(String colName, String value)

Note: This function is deprecated and an alternative function could be MEMLOOKUP orTLOOKUP functions.

Mapping: <TargetField> = LINK(VALUE("SourceField1"), VALUE("SourceField2"))

LINK(String colName, String query, String fieldName, String refValue, String objectName)


Note: This function is deprecated and an alternative function could be MEMLOOKUP orTLOOKUP functions.

The Link function is used to update Salesforce (Target) field with a source value based on the source identifier that remains unique across Salesforce (Target) as well as Source (Ex: Quickbooks) application

The function creates an internally cached table querying the target (Salesforce) database with two columns, first column being the primary key for the table, second for the other column name.
 
It then looks for a string that is same across both Source and Target system before updating the Target LOOK-UP(Salesforce) field with the Source field value.

LINK(String colName, String query, String fieldName, String refValue, String objectName, String valueField)

Note: This function is deprecated and an alternative function could be MEMLOOKUP orTLOOKUP functions.

LOG()

This is not in function2base

Mapping: <TargetField> = LOG(VALUE("SourceField"))

Example : <TargetField> = {LOG("********ChainId"+LEFT(VALUE("Udf_Pa_Pricing"),20));return LEFT(VALUE("Udf_Pa_Pricing"),20);}

The log function gets the value of the target field "udf_pa_pricing" to while performing write operation and can be viewed in logs section for debugging whenever there is an error.

LOOP

This function is different from the conventional '=' operator to map source and target.

<SourceField "loop" TargetField> is used in
scenarios where a grouping the Line Items are required based on the target identifier. It can also be used when the identifier is unique and same across both source and target systems.

Example1:  Salesforce Oppotunity LineItems to QuickBooks Invoice LineItems

Mapping <TargetField> : InvoiceAddRq/InvoiceAdd/InvoiceLine Add [dbsync:loop] "OpportunityLineItems/records"

In the above example for every opportunity Line Item, the loop will create a corresponding Invoice Line Item.

Example2:  Source - Database ; Target - Quickbooks
Database Query : select invoice_no,customerid,item,itemdesc from InvoiceTable
Mapping : InvoiceAddRq/InvoiceAdd/InvoiceLineAdd [dbsync:loop]  "invoice_no/list"

In the above example, we are using "invoice_no" column from the database as an identifier. Based on this identifier we are grouping each row as a line item and then mapping it with Quickbooks Invoice Line Item.

For instance, if the database Invoice table has four rows with "invoice_no" being the same for all the four rows, then the mapping will create one Invoice in Quickbooks with four Line Items rather than creating one Invoice for each row.

LOOKUP(String adapterName, String queryString)

Mapping: <TargetField> = LOOKUP("sourceconnector" , "querystring")

Example:<TargetField> = LOOKUP("Salesforce","select Id from Account where Name='Test'")

Theabove example with fetch the Id from account object of Salesforce from the source application and assigns it to the target field whenever the name field has a value of "Test"

LOWER (String var)

LPAD(String text, String pattern, int pad)

This function is used to pad left side of a string with the specific set of characters. The integer is the total length of the string returned after padding.

Mapping: <TargetField> = LPAD(VALUE("SourceField"), "string", Int)

Example1: <TargetField> = LPAD("tech on the net", "0", 15)

The function would return result as "tech on the net"

Example2: <TargetField> = LPAD("tech on the net", "0", 18)

The function would return result as "000tech on the net"

LSPLIT(String text, String splitter)

This function returns the split value of the string starting from left side of a string till the splitter value.

Mapping: <TargetField> = LSPLIT(VALUE("SourceField"), "string")

Example: <TargetField> = LSPLIT ("tech-on-the-net", "-")

The LSPLIT() would return result as "tech"

MAP(String key, String...mapEntries)

This function returns the value against the key passed from the key-value pair(s) passed via second parameter of the function.

Mapping: <TargetField> = MAP(VALUE("string1", "string2", string3, string4)

Example: <TargetField> = MAP("myKey", "a=b", "c=d", "myKey=myValue")

The MAP function will return "myValue". If key is not present in any of the key-value pairs then function will return empty string.

MEMLOOKUP(String cacheIdentifier, String query)

This function uses unique identifier of a query i.e cacheIdentifier which would load up the dataset for a lookup.This function creates a table in memory for returning the value of a lookup.

Mapping: <TargetField> = MEMLOOKUP(StringCacheIdentifier, StringKey)

Example1: Salesforce object

<TargetField> = MEMLOOKUP("AccountID",VALUE("SourceField") ) 

In this example, AccountID is the memory table created on Account object of Salesforce using MEMTABLE() function. 

Example2: DATABASE TABLE

<TargetField> = MEMLOOKUP("AccountID", VALUE("SourceField") )

In this example, AccountID is the memory table created on dbAccount table of database using MEMTABLE() function.

MEMLOOKUPREGEX(String cacheIdentifier, String key, String regex)

A variant of the MEMLOOKUP function which takes an additional parameter i.e. regex, returns the value of only those key which matches with regex.

The value whose key starts with prefix, or null if not available

This need to be fixed

MEMTABLE(String cacheIdentifier, String query)

This function creates a memory table in the system with key-value pair of the query passed through this function.


You can append the MEMTABLE() at the end of any other mapping.

MAPPING: <TargetField> = VALUE("SourceField") + MEMTABLE(StringCacheIdentifier, StringQuery)

Example : Database Table

<TargetField> =VALUE("SourceField") +MEMTABLE("AccountID","Select ID, Name from dbAccount")

In this example, select ID and name value from dbAccount table for all records in dbAccount Table.

 This need to be fixed.

MID(String text, Int startNum, Int numChars)

This function extracts a substring from the string and returns the substring.

Mapping: <TargetField> = NOTEQUALS("string1","string2")

Mapping: <TargetField> = OR(Boolean, Boolean)

Example : <TargetField> = OR(VALUE("FirstName")==VALUE("LastName"), VALUE("Id")=="123")

In the above function the firstname has a value "Alan" and last name has a value "Chris" and Id field has a value of 456 which is not equivalent to 123 and hence, the function returns false.

This function PARAM extract the values from session which is in the format PARAM.SOURCE_Object.Variable=PARAM.TARGET_Object.Variable and returns the variable value.

Mapping: <TargetField> = PARAM(''string'')

Mapping: <TargetField> = PARAM_PARENT(''string'')

Example: <TargetField> = PARAM_PARENT(VALUE("Description"))

If the value of "Description" starts with "PARAM" and the value is present in the session, then the second text literal is concatenated with "/" and third text literal and returned.

So character 's' will be ignored.

Note: If the search string exists more than once in the second string, the function returns the position of first existence.

Mapping: <TargetField> = SESSION_GET("KEY")

Example: Retrieving the "key" stored in the session

CustomerAddRq/CustomerAdd/Name = SESSION_GET("Account_Name")

In the above example, we are retrieving the KEY ie. "Account_Name" of Salesforce opportunity object stored in the session and value that is being parsed internally in that of what was stored in the session, "Avankia".

SESSION_PUT(String name, String value)

This function stores the key/value pair in the session of that particular process or workflow which is active. This function can only work active workflows within DBSync.

This condition will execute a row only if the field of "opportunityid" has a value and returns true; else false. In the above example the opportunitydid has a value of null and returns false.

VALUE(String xPath)

This function converts the input parameter to be read as string and returns the passed value as string.

MAPPING: TargetField = VALUE("SourceField")

Example: <TargetField> = VALUE("Name")

In the above example the "Name" field is read as string by the system. The "Name" field has a value of "John" which in itself is returned as string.

MAPPING: TargetField = VALUE("SourceField", true)

Example XML Sample : Salesforce object fields
Trigger : select Id, name, account.name from opportunity
The above query will retrieve ID, name and account name from opportunity object of Salesforce. Use VALUE () function to map the lookup field account name to the target field.

<person gender = "female">

<firstname>Alan</firstname>

</person>

<TargetField> = VALUE("Accountperson/Namefirstname", true)

In the above example as the "firstname" attribute has a value of "Alan" so the function will return "Alan" as example. For better understanding lets assume if the firstname has no value in the attribute so the function returns the string as empty string as second parameter is set to true.

Mapping: TargetField = VALUEATTR("xpath","name")

XML Sample :

<person gender = "female">

<firstname>Alan</firstname>

</person>

<TargetField> = VALUEVALUEATTR("CustomerRefperson", "Namegender")

In this example the the CustomerRef object has a Name field in the form of the XML and will return the value of the Name field to the mapped target fieldthe above example the function returns second passed attribute value i.e. female from the xml sample.
