If you then attempt to access an element at row 0, this will throw an error as that row doesn’t exist. Reason: Our Query has returned no records that match the criteria. Error: System.ListException: List index out of bounds: 0 This limit Counts for each transaction and these limits are reset for each execution of a batch of records in the execute method.ħ. Resolution: Limit the query results by adding limit. If you want to insert additionally, you will need to use Batch Apex in which the 50K limit counts per batch execution. Reason: The exception is being thrown because the maximum number of rows we can return in SOQL calls in Apex is 50000. Trigger ContactTriggers on Contact (after update)ĬontactTriggerHandler.isFirstTime = false Public static Boolean isFirstTime = true

#Apex sql where account not equal to null in salesforce code

Resolution: We can create a class with a static Boolean variable with default value true. In the trigger, before executing your code keep a check that the variable is true or not. After you check, make the variable as false.

#Apex sql where account not equal to null in salesforce update

Reason 1: Let’s say in ‘after update’ trigger, a Developer is performing update operation and this leads to recursive call. Following the best practices above should ensure that you don’t hit this limit in the future.ĥ.Non-recursive Parameterized interface method generating infinite recursion error: “Maximum stack depth reached: 1001”: Important: Salesforce cannot disable the Governors Limit or raise it. Learn about the Governor LimitsĢ. Avoid SOQL queries that are inside for loops.ģ. Check out the Salesforce Developer Blog where you can find Best Practices for Triggers.Ĥ. Review best practices for Trigger and Bulk requests on our Apex Code Developer’s Guide.ĥ. Be sure you’re following the key coding principals for Apex Code in our Developer’s Guide. Since Apex runs on a multi-tenant platform, the Apex runtime engine strictly enforces limits to ensure code doesn’t monopolize shared resources. Here are some best practices that will stop the error messages.ġ. If you need to change the context, then you can use annotation which will run the code asynchronously. Resolution: To fix this issue, you’ll need to change your code in such a way that the number of SOQL fired is less than 100. When the number of SOQL queries exceed the limit in a single transaction, then this error is thrown by Salesforce. Reason: We can run up to a total of 100 SOQL queries in a single transaction or context. All the SOQL queries in triggers fired from one call or context will be counted against the limit of 100. Also, as a best practice, always use WHERE clause in your SOQL statements to read the records.Įxample:  įinally, filter out all null records in your Apex query. Resolution: It’s best to try to have that field indexed by checking the “external ID” checkbox when you create that field. Reason: If you query records on object that returns more than 200,000 records and without query filters, it’s possible that you’ll receive the error, “System.QueryException: Non-selective query against large object type.” We’ll go over the a few possible fixes. Reason 2: If you use nested for-loop (for-loop inside another for-loop), then you must use Map(s) to resolve the issue, as it is one of the common reasons for CPU Time Limit Forģ.System.QueryException: Non-selective query against large object type: Due to consumption of too much CPU time limit in a transaction, this error could occur. Reason 1: Based on CPU usage, Salesforce has a timeout limit for each transaction. It will split the transactions.Īnother approach is to use same logic in a batch class to overcome. Resolution: We can use annotation to do DML operation. Non-Setup Objects such as Standard and Custom Objects). Reason: When you try to combine DML operations for both Setup and Non-Setup objects in a same transaction (Where Setup objects such as Group, Group member, Queue SObject, User. Salesforce Errors while developing applications–which involve apex Classes, Triggers, Visualforce pages, etc.-in Salesforce, we may come across different kinds of common errors. These error codes are enumerated messages that correspond to faults in a specific piece of code in application. Writing programs that work when everything goes expected is a good start however, building applications/programs that behave properly when encountering unexpected conditions is where it really gets challenging. (Marijn Haverbeke, 2013). This article explains some of the common errors in Salesforce and the ways to resolve them in an effective manner.
