I am trying to automate an access table make query through vb.net.It works fine the first time, but the second time it fails because the table already exists.Of course i can delete the table through code by it's name, but i want to let my .net-application find out wich table must be deleted. Or maybe there is a solution that doesn't fail with the error "table exists" without first deleting it.[code]

View 3 Replies[Code] my issue is that now i need two cases, first i need a query that will return the date created and modified of the table and i also need to know if its possible to query a list of table names in the database ordered by date created but that have a certain thing in their names. for example the database contains the following tables: [Code] and what i need the query to return is the tables that contain "Data", settings and employees are for the other functions of the program. so the query should return the 4 data tables in order of date created. but i have no idea how to go about doing that in the query, does anyone know how this is done?

View 1 RepliesI have a table (Projects) which is linked to projectVersions on projectID..projectVersions contains several columns on which I'd like to filter a returned project (and associated projectVersions) list. For example there is a "capacity" column and a "country" column. I am doing a filtered list of projects on one page and I'd like to include all projects where any one of the associated projectVersions has a capacity of 750ml and a country of "France" for example.It may be that a particular parameter is not set and so I pass a zero to indicate not to filter on that.I guess this needs some kind of subquery as when I try and do something like this: [code] it doesn't work as the "xxx" bit, being one-to-many, expects me to specify an item to get at the entities within and yet I want to query where ANY of the associated versions match one of the criteria.
View 1 RepliesI have made a Database.mdf that contains a table that Includes 3 diffrent Column Names.
1:"ID" This one i set to an primary key and i have also made it automaticlly put a number in order to the list. Like 1,2,3,4,5 for each data added. Data Type for this is int.
2:"WordCombination" Were i enter my word combination that i want it to look for)
3."TypeofCombination" Were i enter what the program should add to what i typed in texbox1 if it contains the WordCombination.
I want my program to se if texbox1 contains any of those WordCombinations in my database. And if thats true, Then i want it to show whats in the TypeofCombination + the text in texbox1 in texbox2. If i enter "What do you want ?" in Textbox1 i want the program to find that "What do you want ?" contains "you want" like in ID:1 WordCombination:you want. So becuse this is ture it should enter TypeofCombination in this case "Question:" + what i entered in Textbox1 to show in Textbox2.So if i write "What do you want ?" and click start. Textbox2 should show "Question: What do you want ?" If i Write "My name is Jake" and click start. Textbox2 should show "Answer: My name is Jake".If I Write "hello you Hi there Jacob" and click start. Textbox2 should show "Greeting: hello you Hi there Jacob".And i Should be able to add and delete Word Combinations Without having to change the program.
