IDE :: Changing CommandText Changes Parameters?
Sep 14, 2010I'm trying to edit the CommandText for the Insert Command in a TableAdapter in the Designer in vb.net. Whenever I make changes to the CommandText, Visual Studio (2008) automagically changes the Parameters to a Collection consisting of one Parameter thatexisted before editing the Command, immersed in a sea of complete garbage Parameters, and then I either have to undo (unless this was the first thing I tried editing, in which case I have to close the Designer to discard changes and reopen it) or manuallychange ALL the Parameters back to something that isn't complete garbage.
View 2 RepliesMS SQL Server Multiple Commandtext
Jun 8, 2012[Code] The above code does not work. I need for this to check to see if there is a database entry with the office name and today's date. Then if not it needs to tell the user that it is going to create a new entry for todays date. Then the code is trying to enter a new row in the database but it is like i can't use command. commandtext = in two spots. Both SQL commands work if separated but not together in this code. Obviously the abcdefghij are just test entries but it works if it is separated from the other sql command above. Also of course i have changed the datasource above to hide mine.

DB/Reporting :: Changing TableAdapter CommandText At Runtime?
Nov 23, 2009In my app (written in VS 2003) I use OleDbDataAdapter's to load data. I have some functions that enable be to change the OleDbDataAdapter.SelectCommand.CommandText at run time, by adding a "WHERE" or "HAVING" section to the SQL command, or updating the "WHERE " or "HAVING" section. This way I have have generic load data functions. (load all invoices for Customer 123, load all invoices for the year 2009, or load all invoices for Customer 123 for the year 2009).
With the new VS 2008 TableAdapter, the TableAdaper.CommandCollection property is Protected. How can I edit the TableAdaper.CommandCollection(0).CommandText at run time?

View 2 RepliesUse SQLClient Class Along With CommandText To Send SQL INSERT?
Feb 9, 2012My general method up until now is I use SQLClient class along with CommandText to send SQL INSERT, UPDATE, DELETE statements dorectly to the SQL Server from the VB app. I have a function I use that will escape any special characters within any string variables. I put a lot of vb database functions in a module that all of my forms can use. When I need to pass data around I send/add arguments to functions using regular variables, etc... I log all of my SQL queries sent to the server to a log file for troubleshooting.So far this has worked well. I know there are better ways to do this, Stored Procedures for example. But I just have not made that leap yet. I'm about to consider turning my world upside down!
I'm MOSTLY interested in creating custom Classes that represent the various objects in my database (Customers, Projects, Invoices, etc...). Then defining all of the properties each of these classes should have: Customer.ID, Customer.Name, Customer.Status, etc... and would like to "map" that Customer object to the database I'm interfacing with. I figure I can wrap all of the SQL commands into methods within each class, i.e.: myCustomer.Name = "Joe Smith"

Asp.net - Complex Linq Query - Add A .Where() Or .Any() Predicate To Reduce Query Complexity (in VB)?
Sep 14, 2010I have to join two main tables, and I need to filter the results by elements in an ASP.NET web form. These filters are created on the fly so I have to use a lot of where extensions to filter the query. I want to execute the query with as optimized SQL as possible.
I am first doing a simple join between TW_Sites and TW_Investigators. Then there are two sub-tables that are involved. TW_InvestigatorToArea and TW_InvestigatorToDisease. While most of the where clauses are working fine, I have found a performance issue that won't be an issue right now, but will be an issue as the table gets bigger.
The arrays DiseaseCategories and DiseaseAreas would be the results of a CheckBoxList result.

Jul 11, 2010I've got confused at the moment.I've got one database to developed for MLM (Multi level marketing) company.so, there's one Members database.. each member have unique ID called membercode.. and all members can members under them.. can make 2 members down to 1 member.. all members are added in same table named "tbMembers" and for each member there's a "parentID" where I add member's membercode under whome that member is?.. right?
Now what's the matter is .. I want a SQL Query which can go under and under.. like 'John Doe' having two members under him named 'Suzan' and 'Ellie' and 'Suzan' is also having 2 members under her.. and same for Ellie. and for example.. 'John Doe' having about 300 members in his down line? All members are making transactions.. like they purchase product and Invoices are being generated (invoices tables have 'memberID'). Now the query is how to generate query which can calculate John Doe's Downline's TurnOver from invoices table's 'totalAmount' field's SUM?
I'm using Asp.net 2.0 (VB.net) and use SQL Server 2005 Express.
Parameterized Query : Works With Execute Query But Not In Code?
Oct 22, 2009I have created a parameterized query in my tableadapter. Here is the SQL:
SELECT CalcinerID, Comments, CorrectiveActions, CrucibleOxideWt, CrucibleWeight, DCPressure, DCTemperature,
Date, DischargePressure, FeedPressure, FiredCrucibleOxideWt, GmSampleWt, LIMSNumber, LotNumber, MaterialType,
OperatorID, QualLabOperator, QualLabTimeStamp, RecordID, ToteBinNumber [code]....
When I use the Execute Query button in the Tableadapter Query Builder, the query works fine; I get all the rows I expect. However, when I run this in my code, the query behaves like an equality statement (i.e. Lotnumber = @Lotnumber) rather than a LIKE statement (Lotnumber LIKE '%' + @Lotnumber + '%').Here is the code that is not behaving correctly. Note that I have a textbox, LotSearchTextbox, where I enter the portion of the Lotnumber that I want to use as the filter. I also have a button, LotSearchButton:
Private Sub LotSearchButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles LotSearchButton.Click
Try
Dim SomeNumber As Integer = Me.LotCalcinerO2TableAdapter.FillByLotNumber(Me.CalcinerDBDataSet.LotCalcinerO2,[code].....
why the query works in the Query Builder but not in the code?

SELECT DISTINCT USERNAME,IAVERAGE FROM myTable WHERE IAVERAGE > 0 AND DATE_LOGGED='05-07-2012' ORDER BY IAVERAGE LIMIT 0,5 and the result is:
USERNAME ICOUNT IAVERAGE DATE_LOGGED
