The purpose of the class was to allow retrieval of data from a MS-Access database and to manipulate the data. This works well. I can feed an instance of the AdminDatabase class an SQL statement and fill a dataTable with the result ( getDataTable method in the code section. Now I have added data sets to the project using Visual Studio's data designer. Now I am a

问题 Hi I have had a problem with the following query. I am using two IN clauses to find the type=LEFT for only type=JOIN has occurred once. However, the code is breaking. Ultimately, I am trying to find how many animals left the Zoo without ever JOIN the cage.

问题 I have been working on a database design and I'm stuck hitting a wall. I'm ending up with what I'm reading is not a normalized database structure but I'm having issues trying to find a "more correct" design and if this design is acceptable how do I execute it in Access? TLDR: If a table with a single column set as an auto number is an acceptable design, how do you go about inserting a record in it using Access? The segment of the database of concern is creating a structure for storing
