dev.frostlake.functions.scalar.conversion.ToUuid

public class ToUuid extends BuiltInFunction
TO_UUID(s) — the canonical lowercase form of a UUID string. Snowflake accepts ONLY the hyphenated 8-4-4-4-12 form (live-verified: hyphenless and brace-wrapped inputs are errors), so this does too.

    • evaluate

      public Object evaluate(List<Object> args)
      Description copied from class: BuiltInFunction
      Computes the function's result over its already-evaluated argument values. A SQL NULL argument arrives as Java null, and returning null makes the SQL result NULL.
      Specified by:
      evaluate in class BuiltInFunction
      Parameters:
      args - the argument values, in call order
      Returns:
      the function's value for these arguments, or null for SQL NULL
    • canonical

      public static String canonical(String input)
      The lowercase canonical form; NULL for an empty string, which live converts to NULL; and an error mirroring Snowflake's message for any other invalid input.
      Parameters:
      input - the text to convert
      Returns:
      the canonical form, or null
    • getMinArgCount

      public int getMinArgCount()
      Description copied from class: BuiltInFunction
      The fewest arguments a call to this function may pass; fewer is an argument-count error.
      Specified by:
      getMinArgCount in class BuiltInFunction
      Returns:
      the minimum accepted argument count
    • getMaxArgCount

      public int getMaxArgCount()
      Description copied from class: BuiltInFunction
      The most arguments a call to this function may pass; Integer.MAX_VALUE marks a variadic function (see BuiltInFunction.isVariadic()).
      Specified by:
      getMaxArgCount in class BuiltInFunction
      Returns:
      the maximum accepted argument count
