Problem

Write a function to validate input data to prevent SQL injection.

Implement validate_input(data), where data is a list of filter dictionaries. Return True only when every filter has an allowed field, operator, and correctly typed value. Reject malformed structures, unsupported values, control characters, and common SQL injection delimiters or comment markers. The validator must accept ordinary apostrophes in names, such as O'Reilly.

Contract

data is a JSON-compatible list. Each item must contain exactly field, operator, and value. Return a boolean.

Constraints

  • data must be a JSON-compatible list
  • 0 <= len(data) <= 20
  • Each condition must contain exactly field, operator, and value
  • Allowed fields are id, name, and status
  • Allowed operators are =, !=, <, and >
  • ID values are integers from 0 through 20
  • Name values are strings from 1 through 100 characters
  • Status values are active, inactive, or pending
