问题 I have an Access database set up on a domain hosting service. I am connecting to it through SQL. However, I need all of my queries to be case sensitive, and as far as I know the way the server is set up on the hosting service is it's NOT case sensitive. Is there a certain command that I could use in my SQL which would make the query case sensitive? 回答1: I think you can add collate after the WHERE clause. SELECT col FROM table WHERE col COLLATE Latin1_General_CS_AS = 'value' 回答2: Do you need

问题 I have used MS Access a lot, but I was recently asked to help with a SQL Server database. I noticed that simply copying the SQL code from Access over to the server database doesn't work. Could someone please help me replicate the functionality of my SQL code from Access into SQL Server? Below is the SQL View that works within Access: SELECT [LV1]-[LV2] AS Aging, Partition([Aging],1,100,10) AS AgingRange FROM Table1; Aging is a calculated column based off of two columns within my table.

问题 I have a combobox which looks at a table and displays it's 5 columns of data via a query to be used like a search, on most pc's all 5 columns populate with data but on some only the last 3 columns populate and it displays blank FirstName and Surname columns, any idea how this could happen or how to fix it?

问题 Using Access 2007. I have a table Inventory with the following fields: ContainerID FolderID My goal is to find out which FolderIDs correspond to more than one ContainerID, and what the ContainerIDs are for these records.

I tried this with: select ContainerID,FolderID,count(FolderID) from (select

问题 I am trying to set the value of a number field on a table using the value of a bound checkbox on a form. The value needs to be 40 if checked and 0 if unchecked. I'm new to this and have no idea where to start. No, the checkbox was added to a form and is bound to a number field in the table.
