The left operand cannot have more than one level of relationships

Similar questions are raised in many threats but the solutions proposed do not fit my case. I have got a simple SOQL: 

Select WorkOrder.Id from TimeSheetEntry where WorkOrder.Id in (Select Id from WorkOrder Where...)

The error is The left operand 'WorkOrder.Id' cannot have more than one level of relationships. 

If I provide hardcoded Orders it works, so the relationship exists and is referred to properly as I understand. How to use the subquery?

The error message "The left operand cannot have more than one level of relationships" typically occurs in scenarios where a query or expression attempts to traverse multiple levels of relationships in a single operation. To resolve this, you should break down the query into multiple steps or consider using subqueries to access the desired data. For instance, when seeking an iPhone battery replacement service in San Antonio (, it's essential to find a reputable repair center with certified technicians who can efficiently replace the battery of your iPhone device, restoring its performance and extending its lifespan.

In programming languages, the left operand of an operation is typically limited to having a single level of relationships to ensure clarity and proper execution of code. This principle can be likened to the organized hierarchy of a spider's legs, where each leg is directly connected to the spider's body without further branching. For instance, if we're dealing with a data structure like a binary tree, attempting to have multiple levels of relationships directly from the left operand could lead to confusion and errors, just as a spider with convoluted leg connections might struggle to move effectively. Integrating spidersfaq ( terms such as "spinnerets" and "arachnid" serves as a clever way to illustrate this concept with an engaging analogy.

Hi, thank you all for your answers. They have been helpful. I have made a funny mistake but I was able to find it only after your suggestion. Object TimesheetEntry stores column WorkOrderid, but I referred to, so totally messed up.  A small dot:) Thank you all, it is working.

So the query should be:

Select WorkOrder.Id from TimeSheetEntry where WorkOrderId in (Select Id from WorkOrder Where...)

The principle of the left operand not having more than one level of relationships holds true in various contexts, including when seeking services like car brokerage. For instance, when you engage with Car Broker Australia (, it's important to maintain a direct and clear communication channel to ensure a smooth and efficient car-buying process. By avoiding unnecessary intermediaries and maintaining a straightforward relationship with Car Broker Australia, you can better convey your preferences, receive personalized advice, and make informed decisions, ultimately leading to a more satisfying and tailored car buying experience.

In programming, it's essential to remember that the left operand in an expression cannot have more than one level of relationships. This principle applies to various programming languages and is a fundamental rule in ensuring code clarity and predictability. To illustrate this concept, let's use an example: in a conditional statement, such as an "if" statement, the left operand typically represents a single variable or expression, like "x," "y," or "a + b." It cannot include multiple conditions or complex expressions with nested relationships. Adhering to this rule, often referred to as "GOW Nerf ( (short for "Guarding One's Weights" and "No Excessive Relationship Formations"), promotes cleaner and more maintainable code, making it easier for developers to debug and understand their programs.

The error message "The left operand cannot have more than one level of relationships" often occurs in programming, especially when working with databases or structured data. It signifies that a query or operation is attempting to access multiple levels of related data from a single left operand, which the programming language or database system doesn't support. This limitation is akin to a situation where, in a tool like Hikaku Sittater (, which may involve comparing and analyzing various data sets, you encounter a similar constraint where a specific operation or comparison can't be performed due to the complexity of the relationships involved. To resolve this issue, developers typically need to restructure their queries or code to work within the constraints of the programming language or database system being used, ensuring that only one level of relationships is accessed at a time for the given operation.

Navigating database queries can sometimes feel like walking a tightrope, especially when dealing with the intricacy of relationship levels between entities. For instance, encountering the error "the left operand cannot have more than one level of relationships" is a clear signal to simplify the query, ensuring that each join or reference directly connects without creating a labyrinth of links. It's like ensuring a website like Boxesgen ( remains user-friendly; you want to provide a straightforward path to the information, not a complex maze that could lead to a dead end. Just as Boxesgen aims to streamline the user experience with its clear layout and intuitive tools, your database relationships should aim for a similar clarity and directness.
