DB/Reporting :: How To Create/update Tables Programmatically

Nov 10, 2008

A suite of apps will be using various tables out of the same sql server database.Regardless of which app is being used, the database structure must stay current. (ie:contain all the tables/fields to run any/all of the apps)So, when the user starts any of the apps, it needs to check the database, for the existence of all the tables and fields it needs, then update if necessary.

DB/Reporting :: Update 8 Tables In A Transaction?

Apr 25, 2011

I have an application which upon a save button needs to save data to 8 different tables. 7 of those tables will have multiple new records added to them, while 1 will have just one new record. I want to encapsulate this giant Insert operation in a Transaction so that it will not complete unless I can save successfully to all tables.I have considered using Insert commands to a command statement, but adding what amounts to like 50 parameters, and the fact that using a parameterized query means it becomes very difficult to troubleshoot problems such as invalid values in the SQL statement (since I cannot figure out what the statement looks like with values in it

Timeout Using SQLite - Create A Database And Several Tables - To Populate The Tables With Data From Arrays

Jul 25, 2012

I am using VS2008 and SQLite. I have created a database and several tables and am attempting to populate the tables with data from arrays.

The following code (example) works fine but stops after it inserts 30 to 50 records. I am running the VB code in debug mode and when it stops, I press pause to see where it is. It stops on "SQLcommand.ExecuteNonQuery()" and when I press continue (F5) it will insert another 30 to 50 records.

I do not get an error message. Is this a timeout issue? How do I keep the loop running to the end of the array?

Following is example code.

Dim

SQLconnect As New SQLite.SQLiteConnection()

Dim SQLcommand As SQLiteCommand

Creating Tables In Word Programmatically?

Sep 21, 2009

I am generating tables and writing them to word on the fly. I do not know how many tables there will be each time i write the data to word and the problem I am having is the second table is written inside the first cell of my first table. If there was a third table it is put inside the first cell of my second table.Is there a way to move the cursor out of the table? I have tried creating a new range with each table also but the same thing happens.I have also tried things like tbl.Range.InsertParagraphAfter()The closest I came was using the Relocate method, but this only worked for two tables.

Programmatically Fill All Tables In A Strongly-typed Dataset?

Apr 29, 2010

I have a SQL Server database for which I have created a strongly-typed DataSet (using the DataSet Designer in Visual Studio 2008), so all the adapters and select commands and whatnot were created for me by the wizard.

It's a small database with largely static data, so I would like to pull the contents of this DB in its entirety into my application at startup, and then grab individual pieces of data as needed using LINQ. Rather than hard-code each adapter Fill call, I would like to see if there is a way to automate this (possibly via Reflection). [code]...

DB/Reporting :: Join Two Tables IN SQL?

Jun 16, 2010

I am working on a Visual Basic 2008 program using an Access 2000 database. My SQL codereturns no records, but I know the table has a record. A simplified example of the code looks like this:

SELECT Table1.Field1, Table1.Field2, Table1.Field3, Table1.Field4, Table2. Field1, Table2.Field2 FROM Table1 INNER JOIN Table2 ON Table1.Field1 = Table2.Field1 AND Table1.Field2 = Table2.Field2 WHERE Table1.Field1=@Field1 AND Table1.Field2=@Field2;

DB/Reporting :: VBE 2008 Programmatically Use Database?

Nov 5, 2008

I'm using VBE 2008, with .NET 3.5 SP1, and I am trying to programmatically manage a database. Here are the steps I used so far:

1. Project >> Add New >> Local Database >> Cancel Button.
2. Added a table (Files) with three fields (File Path, File Name, and File Type).
3. Went into Data Sources, did Add New Data Source and followed the wizard to add it as a dataset.

I'm not entirely sure where to go from here. I'd like to be able to use queries on this thing, but I don't want to have to use SQL to add to it and such. I've made a little headway in the code, but it's really frustrating because VBA Access was SOOOO much easier to do this kind of thing in. This is what I have for code:

DB/Reporting :: Delete From Multiple Tables?

Feb 6, 2009

I need to write and SQL query that three from three linked tables. Basically there is a 'case_id' column in each table with matching values.

What I have is:

Code:
declare @archiveYears int
set @archiveYears = -7
delete from cw_ht_bacase where case_id in (

As you can see I have the same query in the "in" clause for each statement. Is there a way to normalise this, sort of like C macro. Basically I'd just to define the inner select statement once and use it multiple times.

DB/Reporting :: Query On Related Tables?

Nov 15, 2008

I have a simple "two-tables" database (SQL EXpress) and a very simple application (VB 2008 Express). The two tables are customer and order and their structures are:

customer(IDcustomer, LastName, FirstName) IDcustomer=primary key orders(IDord, Number, Description, IDcust)
IDord=primary key the tables are related (IDcustomer-->ID cust)

In VB2008 environment I create a dataset, by means of Data Source Configuration Wizard, which encompass both customer and order tables (xsd file). By opening xsd file I set the relationship in the following manner:

"Both relation and foreign key constraint"
Update Rule = Cascade
Delete Rule = Cascade

In my form I show customer table in detail-mode and orders table in datagridview-mode. Two Fill method are created in the Load event and they work correctly.In "CustomerTableAdapter" I create, with QueryBuilder, a search query (say LastName query) and I write the following code:

Private Sub frmSearch_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Me.CustomerTableAdapter.FillByLastName(Me.CustomerOrdersDataSet.custom er, "D") 'All Lastnames with first letter = D

DB/Reporting :: Optimize Query (aggregates On Multiple Tables)?

Feb 20, 2008

Code:

Tables:
- Company
- Department
- Employee
- CertificationA
- CertificationB

I am trying to return a recordset that gives some summary information about each company. The fields in my returned recordset should look like the following.

Company.Name, NumberOfDepartments, NumberOfEmployees, NumberOfCertificationA, NumberOfCertificationACompleted, NumberOfCertificationB, NumberOfCertificationBCompleted

There are actually about 10 different Certification tables but, with Certification A and B you should get the hang of it. When an employee starts a certifaction, a record is added to the that certification table.Below is a query I wrote that works (gets me the data I need), but I am unsure if it is the most efficient way. There will be quite a lot of data so performance is an issue.

Code:

Dim sqlNumberOfDepartments As String
sqlNumberOfDepartments = _
"(SELECT COUNT(*) " & _
"FROM DEPARTMENT " & _
