When to reference Apex code variables in soql?
SOQL statements in Apex can reference Apex code variables and expressions if they are preceded by a colon (:). The use of a local variable within a SOQL statement is called a bind.
Why are there too many soql queries in apex?
Consequently, the trigger on Account will fire on update and the Select statement will count within SOQL limit. This mechanism may happen multiple times and that may cause the error. A possible solution is to add another condition before the Select query in your Account trigger.
Why are soql statements caused by the same query?
You should find that the vast majority of your SOQL statements are caused by the same query. Once you know which query it is you can find it in your code and then remove it from the loop it is in. This trigger code is fine. Your underlying issue resides within another block of code in the org.
Why is parameter not passing to server side?
Seems that problem is with below line. You are setting “expname” hard code as accountId. Replace above line with below line. Everything seems to be working fine. Thanks! I tried that way too. But still it’s not working. It seems like the parameter is not passing to the server side. Problem is with your Controller.js.
Can you use a variable in dynamic soql?
However, unlike inline SOQL, dynamic SOQL can’t use bind variable fields in the query string. The following example isn’t supported and results in a Variable does not exist error:
Is there a way to prevent soql injection?
To prevent SOQL injection, use the escapeSingleQuotes method. This method adds the escape character (\\) to all single quotation marks in a string that is passed in from a user. The method ensures that all single quotation marks are treated as enclosing strings, instead of database commands.
Can a dynamic soql query throw a run time error?
If the query does not return the correct sObject type, a run-time error is thrown. This means you do not need to cast from a generic sObject to a concrete sObject. Dynamic SOQL queries have the same governor limits as static queries.
