View 8 RepliesTransferring Data From One Field In A Table In A Database To Another Field In A Different Table But Same Database In .NET?
Jul 22, 2010I am creating a database in VB.NET for a movie rental place. I currently have three forms;
Member Information
DVD Information
Borrow DVDs
What I would like to do is when I am viewing a member's details, if I click a button 'Borrow DVD for Member', the member's ID number transfers over to the Borrow DVDs table in the Member ID which also would hold some information from the DVD Information table, but I'm sure if i can figure out how to do this firstly, I will be able to apply the same rule and work it out myself.I have been trying to use a query statement like;
INSERT INTO [Borrow DVDs].[Member ID] [IN goodstuffvideos.mdb]
SELECT [Member Information].[Member ID]
FROM [Member Information]
but that has been coming up with error codes and completely not working.
Borrow DVDs table fields are: Borrow ID, Member ID, DVD ID Number, Hiring Fee, Borrowing Limit?
DVD Information table fields are: DVD ID Number, Title, Rating, Hiring Fee, Borrowing Limit Member?
Information table fields are: Member ID, Family Name, Given Name, Address, Town/Suburb, Postcode?
The error coming up is; Error in INSERT statement. Unable to parse query text.And under that it says The query cannot be represented graphically in the Diagram and Criteria Pane.
Use An Excel VBA Variable That Contains A Field Name To Be Used In A DAO SQL "ALTER TABLE" Statement For An Access Database?
Jun 23, 2009As you can see below in the code the " & tblName & " will work fine but instead of using the BankName (which the user cannot change because it is in the code) I would like to do the same as I did with the Table name and use a variable that gets its name from an excel spreadsheet rather that an actual name hard coded in a VBA module. I would like the variable field name entered in the Excel Spreadsheet by the user just like the table name is filled in by the user. The problem is getting the ADO SQL string ( cmd.CommandText = "ALTER TABLE " & tblName & " Add Column BankName Char(25)" ) to recognize that the value in the Variable " & fldName & " is the field name to be used.
Sub AddFieldToAccess()
Dim cnn As ADODB.Connection
Dim cmd As ADODB.Command
[code]....
'If I do this I end up with a field named BankName what I need is the name in the variable " & fldName & "
cmd.CommandText = "ALTER TABLE " & tblName & " Add Column BankName Char(25)"

View 2 RepliesMerging Fields From Multiple Tables In Database Into One Field In A New Table?
May 11, 2011I'm looking for a way to combine a field from multiple tables into a single field in a new table. Because the data populating the tables is coming from an outside source, I would prefer not to change the data in the original files. I have a separate table for each year because this is the way the data is provided. The field layout is not consistent from year to year, but each year there is a field that we'll call "score." I'd like to pull the field "score" from each year's table and have it populate a "score" column in a new table along with the year of the data so that all the years' scores are in the same place. Is there a way to do this using Visual Basic + Access?

How can I check if my application requires Access to be installed or not?
