Create and populate Time Dimension
Case We have sensors in our building that output data every minute which we want to use in a dimensional model. Therefore we need a Time Dimension to aggregate data on parts of the day. How do you create and populate a Time Dimension? International Time Dimension Solution Since creating and populating a Time Dimension is a one-time job, T-SQL is probably the best way to accomplish this. For this example we need a Time Dimension on minute level and therefore we have created a loop that executes a insert query 1440 times (24hours * 60minutes). Besides the hours and minutes we also want to add a name of the day part in two languages and a couple of time strings in both 12 and 24hour notation to make this dimension usable for various countries. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85
