Teradata provides the FNC_GetAnyTypeParamInfo library function for accessing information about each TD_ANYTYPE input and output parameter declared in your routine. FNC_GetAnyTypeParamInfo returns the following information for the parameters:

  • The parameter positional index
  • The data type of the parameter
  • Whether the parameter is an input, output, or an INOUT parameter
  • The maximum length, in bytes, for the data type
  • The value n in a DECIMAL(n,m) type or the precision in Interval data types. For example:

    the value p in INTERVAL DAY(p) TO SECOND(n)

  • The value m in a DECIMAL(n,m) type or the fractional seconds precision in TIME, TIMESTAMP, and Interval data types. For example:

    the n value in TIME(n) or INTERVAL DAY(p) TO SECOND(n)

  • The server character set associated with a character data type
  • The name of the data type if the parameter is a UDT
  • An indicator to show if the type is a UDT and if so, what kind of UDT
  • The return type of a TD_ANYTYPE result parameter
  • The number of TD_ANYTYPE parameters
