How to Handle Large Integers Beyond MySQL\'s BIGINT Limitations?

Large Integer Handling Beyond MySQL's BIGINT Limits

MySQL's BIGINT data type may seem like the most extensive integer representation, but limitations arise when dealing with numbers beyond 20 digits.

Options for Exceeding BIGINT Boundaries

When the storage requirement exceeds BIGINT's capabilities, two options emerge:

• Storing as VARCHAR: Twitter API recommends storing large integers as VARCHAR, prioritizing readability and avoidance of mathematical manipulation.

• Alternative Data Types:

  • Floating point numbers offer a broader range but with reduced precision.
  • DECIMAL allows for up to 65 integral digits with decimal(65,0) as the column type.

Reasoning Behind Data Type Selection

The choice between these options depends on the intended usage of the large integer:

• VARCHAR: Suitable for storing raw data that will not undergo mathematical operations.
• Alternative Types: Ideal when calculations or mathematical manipulation is required.

Ultimately, the decision hinges on the desired functionality and balance between range, precision, and performance.
