There's no direct SOQL query to retrieve custom labels based on their value. SOQL is designed to query data stored in Salesforce objects, and custom labels are metadata, not data. They're stored separately and aren't directly accessible through SOQL.

However, you can achieve this indirectly using the Metadata API. The Metadata API allows programmatic access to Salesforce metadata, including custom labels. You would need to use Apex code (or another language that interacts with the Metadata API) to retrieve the label values and then process them to find the one you need.

Here's how you would approach this using Apex:

// Apex code to retrieve Custom Labels and find one based on its value

public class FindCustomLabelByValue {

    public static String findLabelNameByValue(String labelValue) {
        // Query the CustomLabels metadata.
        List<CustomLabel> labels = [SELECT Name, Label FROM CustomLabel];

        // Iterate through the labels and find the matching value.
        for (CustomLabel label : labels) {
            if (label.Label == labelValue) {
                return label.Name; // Return the label's name if value matches.
            }
        }

        return null; // Return null if no matching label is found.
    }

    public static void runExample() {
        String labelValueToFind = 'Your Label Value Here'; // Replace with your desired value
        String labelName = findLabelNameByValue(labelValueToFind);
        System.debug('Label Name: ' + labelName);
    }
}

Explanation:

1. findLabelNameByValue(String labelValue): This method takes the desired label value as input.

2. List<CustomLabel> labels = [SELECT Name, Label FROM CustomLabel];: This is a SOQL-like query, but it's specific to the Metadata API context within Apex. It retrieves all custom labels and their names and values.

3. Loop and Comparison: The code iterates through the retrieved labels, comparing each label.Label with the input labelValue. If a match is found, it returns the corresponding label.Name.

4. return null;: If no match is found, the method returns null.

5. runExample(): This demonstrates how to use the method. Remember to replace 'Your Label Value Here' with the actual label value you're searching for.

To use this code:

1. Create an Apex class in your Salesforce org with this code.
2. Replace 'Your Label Value Here' with the value of the custom label you are trying to find.
3. Execute the runExample() method. The debug log will show the name of the custom label (or null if not found).

Important Considerations:

• Metadata API Access: Ensure that your user profile has the necessary permissions to access the Metadata API.
• Error Handling: In a production environment, you should add robust error handling (e.g., try-catch blocks) to handle potential exceptions.
• Large Number of Labels: If you have a very large number of custom labels, this approach might be inefficient. Consider optimizing it further (e.g., using a map to improve lookup speed).

This approach using the Metadata API and Apex is the most reliable way to find a custom label based on its value. There is no direct SOQL solution. Remember to always test your code thoroughly in a sandbox environment before deploying to production.
