Examples

1. Set command:

• Single value

  • Initiate the 1st value for the list.

    var data = {
            "variable": "list1",
            "value": "Hello"
            };
    
    redis.set(data);

• Hash datatype

  • Insert the hash object {"hkey1":"hval1", ...} to a new variable hash1.

    
    redis.set({"variable": "hash1", "value": {"hkey1":"val1", "hkey2":"val2", "hkey3":"val3"}});

2. Add command:

• List datatype

  • Insert the (repeating and unsorted) array ["lval1", "lval2", "lval3", "lval4"] to the head of an existed variable list1.

    var data = {
            "variable": "list1",
            "value": ["lval1", "lval2", "lval3", "lval4"],
            "index": [0],
            };
    
    redis.add(data);

• Set datatype

  • Insert the (none-repeating and unsorted) array ["sval1", "sval2", "sval3"] to the variable set1.

    var data = {
            "variable": "set1",
            "value": ["sval1", "sval2", "sval3"]
            };
    
    redis.add(data);

3. Get command:

• Hash datatype

  • Get the value of the variable hash1.

    redis.get({"variable": "hash1"}, function(err, res){
        if(err){
            console.log("ERROR: ", err.message);
        } else {
            console.log("Result: ", res.results);
        }
    });

• List datatype

  • Get values of the (repeating & unsorted) array from the variable list1 with the position range from 1 to 3.

    redis.get({"variable": "list1", "index": [1, 3]}, function(err, res){
        if(err){
            console.log("ERROR: ", err.message);
        } else {
            console.log("Result: ", res.results);
        }
    });

4. SQL command:

• Create the database mydb

  redis.sql({"variable": "mydb"}, function(err, res){
      if(err){
          console.log("ERROR: ", err.message);
      } else {
          console.log("Result: ", res.results);
      }
  });

• Create the foo table for mydb database.

  let szSQL = "CREATE TABLE foo (A INT, B TEXT);";
  
   redis.sql({"variable": "mydb", "value": szSQL}, function(err, res){
      if(err){
          console.log("ERROR: ", err.message);
      } else {
          console.log("Result: ", res.results);
      }
  });

• Note: It's not support for RedisEasy-client.

5. Del command:

• Set datatype

  • Delete the entire set1 variable

    redis.del({"variable": "set1"});

• Hash datatype

  • Delete the values with hash keys "hkey1" and "hkey2" from hash object hash1.

    var data = {
            "variable": "hash1",
            "index": ["hkey1", "hkey2"]
            };
    
    redis.del(data);

6. Count command:

• Get the number of elements of the list1

  redis.count({"variable": "list1"}, function(err, res){
      if(err){
          console.log("ERROR: ", err.message);
      } else {
          console.log("Result: ", res.results);
      }
  });

7. Clear command:

• Clear the variable list1

  redis.clear({"variable": "list1"});

8. Expire command:

• Note: It's not support for RedisEasy-client.

• Set the expiration time for the list1 in 10 seconds.

  redis.expire({"variable": "list1", "other":["EX", 10]});
