The FIND() function will search the string "arch" in "search" from the second character and will return the place VALUE of "arch" in "search". So it will return 3 as the place VALUE. So characters 's' and 'e' will be ignored.

TargetField = FIND("arch","search",2)

Example2: SALESFORCE OBJECT FIELDS

READER: Select Id, FirstName, LastName from Contacts

The above query will select Id, FirstName and Last Name from contacts object in Salesforce. You can use FIND() function to check whether LastName is already existing in FirstName and If it is not existing in the FirstName it will return 0 else it will return the place VALUE of the LastName in FirstName.

<TargetField> = LEN(VALUE("FirstName"))

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.

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 internal cached table querying the target (Salesforce) database with 2 columns, 1st column being the primary key for the table, 2nd 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.

LOOP this is not coming in UI

This is a DBSync function different than the conventional '=' operator
used to map Source and Targert.

<SourceField "loop" TargetField> is used in
scenarios wheregrouping of Line Item is 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 OppotunityLineItems to InvoiceLineItems

Mapping : InvoiceAddRq/InvoiceAdd/InvoiceLineAdd [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 example, if the database Invoice table has 4 rows with "invoice_no" being the same for all the 4 rows, then the mapping will create 1 Invoice in Quickbooks with 4 LineItems rather than creating one Invoice for each row.

LOWER (String var)

Returns the lowercase value

Mapping: <TargetField> = LOWER(String)

Example1: STRING PARAMETER

In this example, I will pass string as "SEARCH". The LOWER() function will return the string converted to lowercase. So "SEARCH" will be returned as "search" and that VALUE will be placed in target field.

<TargetField> = LOWER("SEARCH")

Example2: SALESFORCE OBJECT FIELDS

READER: Select Id, FirstName, LastName from Contacts

The above query will select Id, FirstName and Last Name from contacts object in Salesforce. You can use LOWER() function to get length of FirstName or LastName. If the VALUE for FirstName is "Avankia" the resulting string returned by function will be "avankia".

<TargetField> = LOWER(VALUE("FirstName"))

Example 3: DATABASE FIELDS

READER: Select Id, FirstName, LastName from dbContacts

The above query will select Id, FirstName and Last Name from contacts in database. You can use LOWER() function to get length of FirstName or LastName.. If the VALUE for FirstName is "DBSync" the resulting string will be "dbsync".

<TargetField> = LOWER(VALUE("FirstName"))

LPAD
(String text, String pattern, int pad)

Left padding of the string with the value passed in for a specified size.

Mapping: <TargetField> = LPAD(VALUE("SourceField1"), "string", Int)

Example1:
LPAD("tech on the net", "0", 15)
would return "tech on the net"

Example2:
LPAD("tech on the net", "0", 18)
would return "000tech on the net"

LSPLIT
(String text, String splitter)

Returns the Split value of the string starting from first character to the splitter specified.

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

Example:
LSPLIT ("tech-on-the-net", "-")
would return "tech"

MAP(String key, String...mapEntries)

This function returns the value against the key passed from the key-value pair(s) passed 2nd parameter onwards.

MAP("myKey", "a=b", "c=d", "myKey=myValue") will return "myValue". If key is not present the any of the key-value pairs it will return empty string.

MEMLOOKUP(String cacheIdentifier, String key)

This function identifies the value against the key stored in memory table created by MEMTABLE() function. 

Parameter1: catcheIdentifier is the name of Catcheidentifier used in MEMTABLE() function

Parameter2: key is against which value will be returned

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

Example1: SALESFORCE OBJECT 
In this example, AccountID is the memory Table created on Account object in Salesforce using MEMTABLE() function. 

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

Example2: DATABASE TABLE
In this example, AccountID is the memory Table created on dbAccount table in database using MEMTABLE() function.
 
<TargetField> = MEMLOOKUP("AccountID", VALUE("SourceField") )

MEMLOOKUPREGEX(String cacheIdentifier, String key, String regex)

A variant of the MEMLOOKUP function which takes an additional paramter regex, returns the value of only those key which matches regex

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

MEMTABLE(String cacheIdentifier, String query)

This Functions creates a memory table in DBSync for Key Value pair for the Query provided.

Parameter 1: StringCacheIdentifier is the memory table where the key and value pair is saved.

Parameter2: String Query is the query to be executed.
The query should have only 2 columns. First column is value and second column is key column.

Select columnName1, columnName2 from object where condition. where condition is optional.

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

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

Example1: SALESFORCE OBJECT 
In this example, I will select Id and Name value from Account Object for all Accounts. 

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

Example2: DATABASE TABLE
In this example, I will select ID and Name value from dbAccount table for all records in dbAccount Table.
 
<TargetField> = VALUE("SourceField") +MEMTABLE("AccountID","Select ID, Name from dbAccount")

<TargetField> = NUMBER(*VALUE("NumberOfEmployees"))*

OR(boolean exp1, boolean exp2)

Returns the Boolean value of the condition of 2 parameters passed in.

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

Example: SALESFORCE OBJECT FIELDS
READER: Select Id, FirstName, LastName from Contacts

The above query will select Id, FirstName and Last Name from contacts object in Salesforce. You can use OR() function to check whether first name and last name have same VALUE or Id is equal to 123.

If both the conditions are true the function will return true.

If first condition is true and second condition is false the function will return true.

If first condition is false and second condition is true the function will return true.

If both the conditions are false the function will return false.

The REPLACE() function will replace three characters from 3^rd character to 5^th character in the string. The resulting string returned by function will be "search".

TargetField = REPLACE("seaaarch",3,3,"a")

Example2: SALESFORCE OBJECT FIELDS

READER: Select Id, FirstName, LastName from Contacts

The above query will select Id, FirstName and Last Name from contacts object in Salesforce. You can use REPLACE() function to replace specified number of characters of FirstName with specified string. If the VALUE for FirstName is "salesforce" as first parameter, VALUE of start number is 2 as second parameter, VALUE for number of characters is 4 for third parameter, and VALUE of Replace String is "f-", then function REPLACE() will return string "sf-force".

TargetField = REPLACE(VALUE("FirstName"),2,4,"f")

Note: VALUE() function is used inside REPLACE() to convert the FirstName VALUE to string.
