Explain about "Too Many SOQL Error: 101"

Error: System.LimitException: Too many SOQL queries: 101

errors occur when you exceed SOQL queries governor limit. Actuval limit is "you can run up to a total 100 SOQL queries in a single call or context".

resolving this situation:

Change your code by fallowing apex code best practices so that the number of SOQL fired is less than 100.

If you need to change the context, you can use @future annotation which will run the code asynchronously.

Apex runs on a multi-tenant platform, the apex run time engine strictly enforces limits to ensure code does not monopolize shared resources.

Best practices:

• Avoid SOQL queries in for loops.
• Fallow Apex code key principals while writing Triggers and bulk requests.
