JOIN select only one row from second table
SELECT SensorName FROM Table1 WHERE Name = 'MyName';
Lets say, I get 5 rows back
Sensor1,
Sensor2,
Sensor3,
Sensor4,
Sensor5
Now in a different table, I have one row of data, this is the query
SELECT value1, value2, value3, value4, value5 from Table2 Where Name = 'MyName';
and this is what I get back.
value1 value2 value3 value value5
23.1669 14.5974 22.4009 19.9076 33.1585
"Name" is the common field on both the tables
Now I know these two are mapped (sensor names are mapped with the values), so How can I get Something like in single MySQL query
NAME VALUE
Sensor1 23.1669
Sensor2 14.5974
Sensor3 22.4009
Sensor4 19.9076
Sensor5 33.1585
