0 - 1 of 1 tags for parameter marker

A "parameterized" SQL request is when you specify a question-mark parameter marker in place of an expression within the SQL request text. Parameter markers are recommended over SQL literals for a couple of reasons.

  1. Because the SQL request text stays the same as the SQL request is executed multiple times, the Teradata Database statement cache hit ratio can be higher, resulting in better performance.
  2. They help protect against SQL injection attacks.
