问题 If this is a super basic question I apologize; I'm still trying to grok MySQL and my options on interfacing with it. I'm wondering if I'm able to add the mysql schema to MySQL Workbench? I can see and access it via PhpMyAdmin and the command line. I'm also able to query a mysql table (user, for example) from Workbench itself. I'm mostly just curious if I can add it to the schema section in the lower left hand side of Workbench. I'm using version 6.3. Thanks for your time and suggestions! Edit

问题 I have a table name 'polygon_csa', which has two columns 'element_id' as an integer and 'poly' as a four point polygon I am trying to find which polygons enclose a point of my choice. I have tired the following code: Set @x = -60; Set @y = 10; set @xy=ST_geomfromtext(concat('Point (',@x, ' ', @y,')')); Select element_id from polygon_csa where ST_Contains(poly.polygons_csa,@xy); This returns error 1054 'unknown column Poly.polygons_csa in where clause'. I am running MySQL 5.7, is this a bug,

问题 I want to insert some rows in a table using MySQL 5.7 with MySQL Workbench 6.2. When I try it I get the error 1175 (update without WHERE in safe update mode) My query has a WHERE clause in it is filtering the PK of the table too. This is how it looks: > update inventory as inv > > set inv.fk_location = null > , inv.location_description = null > > -- only buffered rows > where inv.id_inventory in ( > select tmp.id_inventory > from tmp_inventory_location as tmp ) The subselect gives two rows
