Salesforce Tips & Tricks

If you wanted to query ‘accountId, account.name’ fields in a query just specify ‘account.name’ which will retrieve ‘accountId’ automatically.
SOQL query can be ORDER BY 32 fields.
SOQL/SOSL statements cannot exceed 10,000 characters.
SOQL query can’t run more than 120 seconds.
For best performance, SOQL queries must be selective, particularly for queries inside of triggers. To avoid long execution times, non-selective SOQL queries may be terminated by the system. Developers will receive an error message when a non-selective query in a trigger executes against an object that contains more than 100,000 records. To avoid this error, ensure that the query is selective.
The maximum number of records that an event report returns for a user who is not a system administrator is 20000; for system administrators is 100000.
Inbound Email Services: Maximum Number of Email Messages Processed (Includes limit for On-Demand Email-to-Case) is number of user licenses multiplied by 1000, up to a daily maximum of 1,000,000.
Inbound Email Services: Maximum Size of Email Message (Body and Attachments) is 10 MB.
Apex Limit: Maximum number of characters for a class is 1 million.
Apex Limit: Maximum number of characters for a trigger is 1 million.
Apex Limit: Maximum amount of code used by all Apex code in an organization1 is 3 MB.
Apex Limit: Default timeout of callouts (HTTP requests or Web services calls) in a transaction is 10 seconds.
Apex Limit: Maximum size of callout request or response (HTTP request or Web services call) is 3 MB.
Apex Limit: Maximum SOQL query run time before the transaction can be canceled by Salesforce is 120 seconds.
Apex Limit: Maximum number of class and trigger code units in a deployment of Apex is 5,000.
Apex Limit: For loop list batch size is 200.

Salesforce where clause of field1 = field2 of same object

You might wanted to bring your records like Select id from Account where Column1 = Column2, which is not possible in Salesforce.
For this you have to create a formula field as Text and then populate this field as TRUE if the column1 = column2 else populate the value as FALSE.
Finally you can write a query as:

select id from Account where formulafield = 'TRUE'

How to show more records in related list in Salesforce?

Biswajeet April 8, 2014 No Comments

When viewing a record detail page (e.g. Contact detail) the related lists (e.g. Cases related list) shows a limited number of related records at a time.

So, if you have more than 5 (by default) Cases tagged to an Contact, in the Contact detail page, you will see Show m more » | Go to list (n+) ». By default a will be 5 and b is total number of the records.

You can scroll down to the bottom of page, and look for Always show me more records per related list or Always show me fewer / more records per related list if you have click more before (even in previous login).
Always show me more records:

Always show me fewer / more records:

Clicking more or fewer increases and decreases the default number 5 (by default) of related list records displayed for all object record detail pages for the logged in user. If you notice, when you click more or fewer link, in the URL, Salesforce will add parameters rowsperlist=m (e.g. https://ap1.salesforce.com/0039000000ojedc?rowsperlist=10), this parameter will show related list up to 10 records for all related list.
Note: This change will be permanent for the logged in user for all tab, and can increase the related list records up-to 100.

SOQL For Loop

Biswajeet March 19, 2014 No Comments

The SOQL for loops iterate over ALL the sObjects returned by a SOQL query. Here is the syntax for the for loop in SOQL:

Option 1 – (Include the SOQL in the loop definition):

for (someVariables : [soql_query])
{
    //Your Code
}

Note: The variables above must be of the same type as the sObject that are returned by the soql_query. Here’s an example below of a simple for loop function that uses the clauses WHERE and LIKE:

String s = ‘Biswajeet Samal’;
For ( Lead a : [SELECT Id, Name from Lead where Name = : (s)])
{
    //Your Code
}

Option 2 – (Create a list of results (sObject list) first and then loop through them):

// Create a list of account records from a SOQL query
Account[] accs = [SELECT Id, Name FROM Account WHERE Name =  'Biswajeet Samal'];
  
// Loop through the list and update the Name field
for(Account a : accs){
   a.Name = 'Biswajeet Samal';
}

Introduction to Salesforce.com Object Query Language (SOQL)

Biswajeet March 19, 2014 No Comments

An introduction to Salesforce.com Object Query Language (SOQL):

As a developer looking to extend Salesforce.com, SOQL is very important and powerful aspect of coding. You can use SOQL to build your own custom query stings. These query strings can be used in the following places:

Apex statements
Visualforce getter methods and controllers
In the queryString param passed in the query() call
Finally, you can use the Schema Explorer in the Eclipse Toolkit

For those are familiar with SQL, will find some differences.

SOQL uses the “SELECT” statement combined with any filter statements to bring back sets of data. The data sets returned may be optionally ordered as well (just like in SQL).

Here is a basic SOQL Select example:

SELECT field1, field2, field3
FROM an object
WHERE filter statement(s) and (optionally) order the results

If you want to get all the names for opportunities created in the last 30 days.
you would use the following SOQL statement:

SELECT Name
FROM Opportunity
WHERE CreatedDate = Last_N_Days:30

If you want to get all the Leads from your Salesforce.com account where the email address equals = “biswajeet@somecompany.com” you would use the following SOQL statement:

SELECT ID, Name from Lead WHERE email = 'biswajeet@somecompany.com'

SOQL – COUNT():

Getting the “Count” of results being returned in a SOQL data set is pretty simple as well.
For example, if I wanted to know how many Leads were going to be returned in my SELECT statement above, I can use the COUNT() function below:

SELECT COUNT() from Lead WHERE email = 'biswajeet@somecompany.com'

SOQL – Comparison Operators:

Operator	Common name
=	Equals
!=	Not equals
<	Less than
<=	Less than or equal
>	Greater than
>=	Greater than or equal
IN	In
NOT IN	Not in (WHERE clause)
INCLUDES EXCLUDES	Applies to multi-select picklists
LIKE	Like (see section below)

SOQL – Like Operator:

The LIKE operator provides a way to match partial text strings and includes support for wildcards. Let’s say for a moment we want to find all the Leads where the email domain is the same. For this, we can use a “LIKE” operator. He is an example of a LIKE statement with the % wildcard.

The placement of the percent sign ‘%’ is key here. I am basically saying, bring me back all the Leads where the email ends with “somecompany.com”. Therefore I place the ‘%’ at the beginning of whatever I am looking for.” Anything to the left of the % sign is ignored in the search. If I didn’t know the full domain I could use the following statement:

SELECT Id, Name from Lead WHERE email  LIKE '%somecompany.com'

This is going to return all the leads where the email contains “somecomp”.

SELECT Id, Name from Lead WHERE email  LIKE '%somecomp%'

Other wildcard is the underscore “_”. Thing is used to match exactly one character.
Note: Unlike with SQL, the LIKE operator in SOQL performs a case-insensitive match.

SOQL – WHERE/OR:

If you want to extend the WHERE clause to include multiple values, you can OR. See the example statement below:

SELECT ProductCode FROM PricebookEntry WHERE CurrencyIsoCode = 'USD' or CurrencyIsoCode = 'GBP'

Taking it a step further, you can evaludate multiple things in the WHERE clause:

SELECT ProductCode,UnitPrice FROM PricebookEntry
WHERE (UnitPrice >= 10 and CurrencyIsoCode='USD')
OR (UnitPrice >= 5.47 and CurrencyIsoCode='EUR')
