Examples

Consider the following filter expressions: user = "root", rowsProduced > 0, fileFormats RLIKE ".TEXT.*", and executing = true. In the examples:

  • The filter attributes are user, rowsProduced, fileFormats, and executing.
  • The operators are =, >, and RLIKE.
  • The filter values are root, 0, .TEXT.*, and true.
