问题 I need help creating a query to generate the results I am looking for. I'm creating an application to track employee attendance based off an existing database table. The user selects a date or group of dates from a calendar (say 10/1/18 , 10/2/18 and 10/3/18 ).

问题 Take the following input: update sys.assemblies set permission_set_desc = 'EXTERNAL_ACCESS' where assembly_id = <someInt> and name not like 'microsoft%' and the following output: Msg 259, Level 16, State 1, Line 2 Ad hoc updates to system catalogs are not allowed. This is in SQL Server 2012. I'm logged in as "sa", so this is probably not a user permissions issue. Links I'm finding on Google are either void of solutions or hard for me to follow. How do I get past this without producing

问题 When I apply STBuffer(1) to a Point in SQL Server Spatial, they show up as an oblong circle, instead of a perfect circle. Why is this? 回答1: The selected projection is Equirectangular , and not the more familiar Mercator that we see in Google Maps & Bing Maps. Change this and the points will show up as expected.

问题 I am using SQL Server and creating a table (example is at the very bottom of this question).
