VS 2010 Records In Table Are Determined By Records In Another Table?

Apr 22, 2012

I have a database with 3 tables: Student, Unavailability and Duty.The fields for Student are entered in a form I have. One of the fields in Unavailability is filled by a form, the other fields are an autonumber and a foreign key to the Student table.ow I want records in the Duty table to be created and automatically filled in depending on what the values of the fields are in the Student table.For example, If the Boarder field in the Student table is 'yes' then I want the Duty Number field in the Duty table to be '1', '3' and '4'. If it is 'no' then I want the value to be '2' and '5'. I recognize it will have to create several different records to incorporate the different duty numbers for each StudentID. Obviously this will require an if statement, however this is my first time implementing a database with my limited experience with programming and Visual Basic, so I don't know how to refer to the specific fields in a table and set the value of other fields depending on the data in other fields.

VS 2010 Insert Records In One Table From Another Table With Sql Satement?

Mar 27, 2012

I do this in Oracle databases just in a snap, but now I have to do it in VB using ADODB and I don't know how to do it.

I have two Access 2007 tables. Table A contains: Col1 (text), Col2 (text), Col3(date), Col4(amount), Col5(text)

Table B contains Col1(date), Col2(amount) What I need to do is to insert into table B the records of table A (col4 summed) grouped by date of table A. The date is a variable contained in a text box so it cannot be hardcoded into the SQL statement.

Cannot Delete New Records In Access Database

Feb 17, 2008

I'm creating an application that adds and deletes records from a microsoft access database. The language I'm using is VB2008. I am importing the database through a wizard. I can add records and delete records, but I cannot delete a newly added record without closing the form first. When i reopen the form, I can delete the record. Here is how I have my database setup:

'Bind user info to the controls.
AUSERDataSet = New BulldogUsersDataSet
AUSERTableAdapter = New BulldogUsersDataSetTableAdapters.UsersTableAdapter
AUSERTableAdapter.Fill(AUSERDataSet.Users)
' Setup the binding source.
AUSERBindingSource = New BindingSource

Database - Delete Records From Ms Access?

Dec 21, 2009

how to do it, but the tutorial is not applicable on the program that I wish to do. The tutorial tells you to add 4 navigation buttons so that you can navigate the database(first, last, back, and forward). Then an update and delete button. But if this is what I will do, it would take 10 years to navigate the database and update a record. Now, what I want to do is just for the user to input a unique ID and click search button(which I have already done). Then the update would be easier. How can I update or delete a record using this method?

Delete Duplicate Records From Combobox?

Apr 28, 2010

I currently have a sql database linked to vb.net and I'm populating the comboboxes using SELECT statements. However, I'm getting duplicate records in the comboboxes.I have my database setup as 1 project to many submittals and 1 submittal to many items.

I have 3 projects in my sample dataset and I'll recieve 3 duplicate submittals and 3 duplicate items.

If I have 6 projects in my sample dataset than I'll get 6 duplicate submittals and 6 duplicate items.

I've tried adding distinct to my SQL statement, but that didn't do anything. Is there any reason why its showing as many duplicates as I have projects?

Delete Records From The Database If They Are At-least 3 Years Old?

Dec 19, 2011

I have a project that I am working on that requires me to delete records from the database if they are atleast 3 years old.I have something like this in DB2 SQL to get the date:

SELECT * FROM tableA
WHERE ADD_DATE < CHAR(CURRENT DATE-3 YEARS)

ADD_DATE is stored as Characters in my system, this is why I am converting I know it is also possible to get the date and format it in VB.net which is the language I am using to call the SQL statements.My question is whether it would be faster/better to get the date and perform the conversion inside the SELECT in SQL or would it be better to get the current date and convert it in VB.net and then use that date in the SQL statement. I'm thinking VB.net would be better because there are thousands of records that must be compared. I should be able to set it up in VB so that it only retrieves the date and converts it once but I am not sure what kind of performance hit each takes from these statements.

.Net CommandBuilder Will Update, Insert, But Not Delete Records In SQL DB?

Feb 15, 2012

I have a datatable populated from an SQL Server 2008 database table. I created a DataAdapter with a commandbuilder to manage the updating, inserting, and deleting of records. The Updating and Inserting work as expected. However, Delete does not. The code runs through just fine without any errors. The number of records in the datatable after the row is deleted even reflects the deletion. The DataAdapter.Update works fine without any exceptions. But when checking the actual table in the SQL DB the deleted record is still there.Here are the parts of my code that deal with this table.
