Increment the number values at the path by a given number.
Syntax
JSON.NUMINCRBY <key> <path> <number>
key (required) – key of JSON document type
path (required) – a JSON path
number (required) – a number
Return
If the path is enhanced syntax:
Array of bulk Strings representing the resulting value at each path.
-
If a value is not a number, its corresponding return value is null.
-
WRONGTYPEerror if the number cannot be parsed. -
OVERFLOWerror if the result is out of the range of 64-bit IEEE double. -
NONEXISTENTif the document key does not exist.
If the path is restricted syntax:
Bulk String representing the resulting value.
-
If multiple values are selected, the command returns the result of the last updated value.
-
WRONGTYPEerror if the value at the path is not a number. -
WRONGTYPEerror if the number cannot be parsed. -
OVERFLOWerror if the result is out of the range of 64-bit IEEE double. -
NONEXISTENTif the document key does not exist.
