/AWS1/CL_SRDFIELDSTATS

The statistics for a field calculated in the request.

CONSTRUCTOR

IMPORTING

Optional arguments:

IV_MIN TYPE /AWS1/SRDSTRING /AWS1/SRDSTRING

The minimum value found in the specified field in the result set.

If the field is numeric (int, int-array, double, or double-array), min is the string representation of a double-precision 64-bit floating point value. If the field is date or date-array, min is the string representation of a date with the format specified in IETF RFC3339: yyyy-mm-ddTHH:mm:ss.SSSZ.

IV_MAX TYPE /AWS1/SRDSTRING /AWS1/SRDSTRING

The maximum value found in the specified field in the result set.

If the field is numeric (int, int-array, double, or double-array), max is the string representation of a double-precision 64-bit floating point value. If the field is date or date-array, max is the string representation of a date with the format specified in IETF RFC3339: yyyy-mm-ddTHH:mm:ss.SSSZ.

IV_COUNT TYPE /AWS1/SRDLONG /AWS1/SRDLONG

The number of documents that contain a value in the specified field in the result set.

IV_MISSING TYPE /AWS1/SRDLONG /AWS1/SRDLONG

The number of documents that do not contain a value in the specified field in the result set.

IV_SUM TYPE /AWS1/RT_DOUBLE_AS_STRING /AWS1/RT_DOUBLE_AS_STRING

The sum of the field values across the documents in the result set. null for date fields.

IV_SUMOFSQUARES TYPE /AWS1/RT_DOUBLE_AS_STRING /AWS1/RT_DOUBLE_AS_STRING

The sum of all field values in the result set squared.

IV_MEAN TYPE /AWS1/SRDSTRING /AWS1/SRDSTRING

The average of the values found in the specified field in the result set.

If the field is numeric (int, int-array, double, or double-array), mean is the string representation of a double-precision 64-bit floating point value. If the field is date or date-array, mean is the string representation of a date with the format specified in IETF RFC3339: yyyy-mm-ddTHH:mm:ss.SSSZ.

IV_STDDEV TYPE /AWS1/RT_DOUBLE_AS_STRING /AWS1/RT_DOUBLE_AS_STRING

The standard deviation of the values in the specified field in the result set.
