View 1 RepliesI have this piece of code wich works perfectly when inserting records into one table using records from another table. My question is that now i need to create another table by using records from 3 other tables (tables are related). Can i use aliases on the column names, like on Oracle SqlPlus? How will be the syntax of the 'INSERT INTO SQL statement?

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.

Relatively new to VB.NET coding. Am creating a pretty simple console application that needs to insert over 50,000 records into an Oracle table (OleDB connection). I tried 3 different methods so far: Individual INSERT, insert using a dataset, & using INSERT ALL (commit every 25 records due to # of columns). It seemed like most articles/posts I read recommended the dataset approach, but the INSERT ALL code was definitely the fastest by far.
View 15 RepliesI am rather new to vb.net using SQL CE. This is using 3.5 framework. I am trying to use a button to insert records into a table in a SQL CE database. Rowsaffected returns a value of 1, but when I preview the data, the row is never inserted. The sql statement I am using uses hardcoded values only because I am trying to get this to initially work. Once I can get the insert statement to work, it will use variables based on user input.
Here is my code that I am using:
Private Sub cmdInsert_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdInsert.Click
Dim connstr As String
Dim rowsaffected As Integer
connstr = ("Data Source =" _
+ (System.IO.Path.GetDirectoryName(System.Reflection .Assembly.GetExecutingAssembly.GetName.CodeBase) _
+ ("jhepfner.sdf;")))
[Code] .....
The original database that I am using is c:jhepfner.sdf. When I run this, connstr shows:
Data Source =Program Filesjhepfnerjhepfner.sdf;
In server explorer, it shows the connection string as:
Data Source=C:Documents and SettingsCompaq_OwnerLocal SettingsApplication DataTemporary Projectsjhepfnerjhepfner.sdf

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.

With the code above, I'm trying to create and insert records into a MySQL database. The issue here is that not all records are inserted. If the XML document I'm reading from has 80 records, only 40, or 66, or some other number get put into the database. I'm guessing this is because the code is trying to insert the records faster than the database can handle them? What would the correct way to make sure the record is in the database before moving on to the next one?
queryStr = "INSERT INTO tbl_user_ldr_responses (rec_num, ques_no, response, comment) " & _
recnum & ", " & "1, " & "'', " & reader.GetValue(1) & " UNION ALL" & _
recnum & ", " & "2, " & "'" & reader.GetValue(2) & "', " & "''"

I have a program that is using a dataset class, table adapter, binding source and binding navigator. The program can read, update, and delete rows from the table. However, it doesn't recognize new records and save them to the database when the table adapter's update method is called. (table was pre-populated by another process) The database table is using an identity column for the primary key. On a whim I added code to force an insert of data using the table adapter's Insert method with some hard coded values and this worked.This code was invoked after hitting new record on the binding navigator bar. Looking at the database, I notice the record I forced in skipped an identity value, which indicates to me hitting new record took the previous number. So the question I have is what would keep the tableadapter from inserting the new record when its update method is called?
