+#### Using the Query Builder
+The query builder provides a simple user-friendly interface to help you quickly set up your query. The builder enables you to define the basic parts of your query, The common ones are:
+1. The table you want to query from
+2. The time field and metric field
+3. WHERE clause - You can use one of the pre-defined macros to speed your writing time or set up your own Expression. Existing Macros are:
+   
+   a. Macro $__timeFiler with last 7 days  example:
+```
+  WHERE `createDate` BETWEEN TIMESTAMP_MILLIS (1592147699012) AND TIMESTAMP_MILLIS (1592752499012) AND _PARTITIONTIME >= '2020-06-14 18:14:59' AND _PARTITIONTIME < '2020-06-21 18:14:59'
+``` 
+   b. Macro $__timeFrom with last 7 days  example:
+```
+  WHERE `createDate` > TIMESTAMP_MILLIS (1592223758609)  AND _PARTITIONTIME >= '2020-06-15 15:22:38' AND _PARTITIONTIME < '2020-06-22 15:22:38'
+```
+   c. Macro $__timeTo with last 7 days  example:
+```
+  WHERE `createDate` < TIMESTAMP_MILLIS (1592828659681)  AND _PARTITIONTIME >= '2020-06-15 15:24:19' AND _PARTITIONTIME < '2020-06-22 15:24:19'
+```
+
+4. GROUP BY option - You can use a pre-defined macro or use one of the fields from your query
+    a. time ($__interval,none)
+5. ORDER BY option
+
+Note: If your processing location is not the Default US one set your location from the processing Location drop-down at the top right bottom of the query builder
+
+###Troubleshooting
+   Viewing your Query
+   1. Use The Query Inspector located at the top of the query builder
+   
+   2. The query Inspector enables you to see the clean query and troubleshoot SQL errors
+   
+   The Query builder comes with a set of defaults which are control from the top of the Query Builder
+
