Summary
| Command Name | HGETAll |
| Usage | Get all fields and value of a hash |
| Group |  hash |
| ACL Category | @read @hash @fast |
| Time Complexity | O(N) |
| Flag | READONLY |
| Arity | 2 |
Notes
- In the time complexity representation, N is the size of the hash.
Signature
HGETALL <key>
Usage
Get all the fields and values of a hash. By only providing the key of the hash we get all the fields and values. We do not need to be aware of specific field(s).
Notes
- The response contains the field and value of the field in 2 separate lines.
Arguments
| Parameter | Description | Name | Type |
|---|---|---|---|
| <key> | Name of the key of the hash | key | key |
Return Value
| Return value | Case for the return value | Type |
|---|---|---|
| All fields/values of hash | All fields/values of the hash | object |
| (empty array) | If the key does not exist | null |
| error | On successful we get a map of the field and values of the hash | error |
Notes
- If the command is applied to a key that is not a hash, then the following error is returned-
(error) WRONGTYPE Operation against a key holding the wrong kind of value
Examples
Here are a few examples of the usage examples of the Redis HGETAll command-
# Redis HGETALL command examples
# Set some has fields using HSET
127.0.0.1:6379> hset customer:1099:address street "5342 Hollister Ave" city "Santa Barbara" state California zip 93111 phone "(805) 845-0111" country "United States"
(integer) 6
# Get all field/value of the hash
127.0.0.1:6379> hgetall customer:1099:address
1) "street"
2) "5342 Hollister Ave"
3) "city"
4) "Santa Barbara"
5) "state"
6) "California"
7) "zip"
8) "93111"
9) "phone"
10) "(805) 845-0111"
11) "country"
12) "United States"
# Try to use HGETALL on a non existing key
# we get (empty array)
127.0.0.1:6379> hgetall somenonexistingkey
(empty array)
# Set a string value
127.0.0.1:6379> set bigboxstr "some string in the box"
OK
# Try to use the HGETALL on a string type of key
# We get an error
127.0.0.1:6379> hgetall bigboxstr
(error) WRONGTYPE Operation against a key holding the wrong kind of value
Notes
- On success, we get the field and value in separate lines, like below-
1) field1 name
2) value of field1
3) field2 name
4) field2 value
... - If the key does not exist we get-
(empty array)
