  • VB working with SQL DB - end of row count, keeps looping

    - by Tramd
    I'm adding to a combo box an ID and a name that i'm pulling from a database. My problem is that for some reason my loop doesnt end once it reaches the end of the records in the database table. Here's my code: For intcount = 0 To dtOrders.Rows.Count - 1 cmbSearch.Items.Add(dtOrders.Rows(intcount)("EmployeeID").ToString & " " & dtOrders.Rows(intcount)("EmployeeLastName").ToString & ", " & dtOrders.Rows(intcount)("EmployeeFirstName").ToString) Next Shouldnt the .rows.count - 1 stop it once it reaches the last record? It loops 4 times through.

  • Turn Function or Stored Procedure Result into "live" Result for LINQ

    - by Alex
    Is it possible to turn result sets obtained in LINQ through a stored procedure or function call into a "live" set of objects of which I can retrieve Foreign Key related objects? If, for example, my stored procedure returns a set of rows (= LINQ objects) of type "Contact", then I can't seem to obtain Contact.BillingAddress (which is related by Foreign Key). Any idea how to make this work?

  • SQL to return dates that fall in period and range

    - by Nate
    Hey stackers, I’ve been grinding my head on this for a while… My goal is to return all dates that fall between a start and end date and have a certain period as a factor, from the start date. (hard to explain) For example… Start Date: Nov 20, 1987; End Date: Jan 01, 1988; Period: 10 days; I want these dates: Nov 20, 1987; Nov 30, 1987; Dec 10, 1987; Dec 20, 1987; Dec 30, 1987; I already have a date table with all dates from 1900 to 2099. The period could be by days, months or years. Any ideas? Let me know if you need more info.

  • How to select records as columns in SQL

    - by Leigh
    Hi, I have two tables: tblSizes and tblColors. tblColors has columns called ColorName, ColorPrice and SizeID. There is one size to multiple colors. I need to write a query to select the size and all the colors (as columns) for a that size with the price of each size in its respective column. The colors must be returned as columns, for instance: SizeID : Width : Height : Red : Green : Blue 1---------220-----220----£15----£20-----£29 Hope this makes sense Thank you

  • SQL Access INSERT INTO Autonumber Field

    - by KrazyKash
    I'm trying to make a visual basic application which is connected to a Microsoft Access Database using OLEDB. Inside my database I have a user table with the following layout ID - Autonumber Username - Text Password - Text Email - Text To insert data into the table I use the following query INSERT INTO Users (Username, Password, Email) VALUES ('004606', 'Password', '[email protected]') However I seem to get an error with this statement and according to VB it's a syntax error. But then I tried to use the following query INSERT INTO Users (Username) Values ('004606') This query seemed to work absolutely fine... So the problem is I can insert into just one field but not all 3 (excluding the ID field because it's an autonumber). Any help would be appreciated, Thanks

  • SQL multiple primary keys - localization

    - by Max Malmgren
    I am trying to implement some localization in my database. It looks something like this (prefixes only for clarification) tbl-Categories ID Language Name tbl-Articles ID CategoryID Now, in my tbl-Categories, I want to have primary keys spanning ID and language, so that every combination of ID and language is unique. In tbl-Articles I would like a foreign key to reference ID in categories, but not Language, since I do not want to bind an article to a certain language, only category. Of course, I cannot add a foreign key to part of the primary key. I also cannot have the primary key only on the ID of categories, since then there can only be one language. Having no primary keys disables foreign keys altogether, and that is also not a great solution. Do you have any ideas how I can solve this in an elegant fashion? Thanks.

  • Displaying tree path of record in SQL Server 2005

    - by jskiles1
    An example of my tree table is: ([id] is an identity) [id], [parent_id], [path] 1, NULL, 1 2, 1, 1-2 3, 1, 1-3 4, 3, 1-3-4 My goal is to query quickly for multiple rows of this table and view the full path of the node from its root, through its superiors, down to itself. The ultimate question is, should I generate this path on inserts and maintain it in its own column or generate this path on query to save disk space? I guess it depends if this table is write heavy or read heavy. I've been contemplating several approaches to using the "path" characteristic of this parent/child relationship and I just can't seem to settle on one. This "path" is simply for display purposes and serves absolutely no purpose other than that. Here is what I have done to implement this "path." AFTER INSERT TRIGGER - requires passing a NULL path to the insert and updating the path for the record at the inserted rows identity INSTEAD OF INSERT TRIGGER - does not require insert to have NULL path passed, but does require the trigger to insert with a NULL path and updating the path for the record at SCOPE_IDENTITY() STORED PROCEDURE - requiring all inserts into this table to be done through the stored procedure implementing the trigger logic VIEW - requires building the path in the view 1 and 2 seem annoying if massive amounts of data are entered at once. 3 seems annoying because all inserts must go through the procedure in order to have a valid path populated. 1, 2, and 3 require maintaining a path column on the table. 4 removes all the limitations of the above but require the view to perform the path logic and requires use of the view if a path is to be displayed. I have successfully implemented all of the above approaches and I'm mainly looking for some advice. Am I way off the mark here or are any of the above acceptable? Each has it's advantages and disadvantages.

  • Encrypt column data with LINQ

    - by kape123
    I was wondering if there is easy solution to this or I'm stuck with following: When updating DB: dti.Pass = Crypter.Encrypt(dti.Pass); _db.SubmitChanges(); When selecting from DB: Data.DbTableItem dti = _db.Single(a=a.Id == id); dti.Pass = Crypter.Decrypt(dti.Pass); Meaning - I am not really into writing repetitive code and this seems like logical thing to be supported by LINQ; so I'm wondering if it is.

  • T SQL WHERE Clause

    - by johniom
    Hiya Guys, I'm trying to develop some code which pulls latest informtion only. What it is when a user goes into a form there a subtable and everytime they change something it creates a new row in the colum called type12_OriginalNoteID which puts its own unquie number in. Another feild called type12_OriginalNoteID keeps the same number - which keeps track of what the oringal number was before any changes were made. I do have some code which does pull the latest information but it does not pull anything if the user has not made any changes to the form - and thats because the type12_OriginalNoteID is null. The code is as follows ea.type12_NoteID IN (SELECT TOP 1 ea.type12_NoteID FROM UserAssessv1aidsadaptations ea1 WHERE ea.type12_NoteID = ea1.type12_OriginalNoteID ORDER BY ea.type12_UpdatedDate DESC) An example of the data is as follows :- type12_note ID - 12 type12_OriginalNoteID NULL type12_UpdatedDate - 11/03/2010 What would be the solution to show the ifnroamtion if no one has made any changes to the subtable? - adding an if statement to run if type12_OriginalNoteID is null??

  • Linq to sql C# updating reference Tables

    - by Laurence Burke
    ok reclarification I am adding a new address and I know the structure as AddressID = PK and all other entities are non nullable. Now on insert of a new row the addrID Pk is autogened and I am wondering if I would have to get that to create a new row in the referencing table or does that automatically get generated also. also I want to be able to repopulate the dropdownlist that lists the current employee's addresses with the newly created address. static uint _curEmpID; protected void btnAdd_Click(object sender, EventArgs e) { if (txtZip.Text != "" && txtAdd1.Text != "" && txtCity.Text != "") { TestDataClassDataContext dc = new TestDataClassDataContext(); Address addr = new Address() { AddressLine1 = txtAdd1.Text, AddressLine2 = txtAdd2.Text, City = txtCity.Text, PostalCode = txtZip.Text, StateProvinceID = Convert.ToInt32(ddlState.SelectedValue) }; dc.Addresses.InsertOnSubmit(addr); lblSuccess.Visible = true; lblErrMsg.Visible = false; dc.SubmitChanges(); // // TODO: add reference from new address to CurEmp Table // SetAddrList(); } else { lblErrMsg.Text = "Invalid Input"; lblErrMsg.Visible = true; } } protected void ddlAddList_SelectedIndexChanged(object sender, EventArgs e) { lblErrMsg.Visible = false; lblSuccess.Visible = false; TestDataClassDataContext dc = new TestDataClassDataContext(); dc.ObjectTrackingEnabled = false; if (ddlAddList.SelectedValue != "-1") { var addr = (from a in dc.Addresses where a.AddressID == Convert.ToInt32(ddlAddList.SelectedValue) select a).FirstOrDefault(); txtAdd1.Text = addr.AddressLine1; txtAdd2.Text = addr.AddressLine2; txtCity.Text = addr.City; txtZip.Text = addr.PostalCode; ddlState.SelectedValue = addr.StateProvinceID.ToString(); btnSubmit.Visible = true; btnAdd.Visible = false; } else { txtAdd1.Text = ""; txtAdd2.Text = ""; txtCity.Text = ""; txtZip.Text = ""; btnAdd.Visible = true; btnSubmit.Visible = false; } } protected void SetAddrList() { TestDataClassDataContext dc = new TestDataClassDataContext(); dc.ObjectTrackingEnabled = false; var addList = from addr in dc.Addresses from eaddr in dc.EmployeeAddresses where eaddr.EmployeeID == _curEmpID && addr.AddressID == eaddr.AddressID select new { AddValue = addr.AddressID, AddText = addr.AddressID, }; ddlAddList.DataSource = addList; ddlAddList.DataValueField = "AddValue"; ddlAddList.DataTextField = "AddText"; ddlAddList.DataBind(); ddlAddList.Items.Add(new ListItem("<Add Address>", "-1")); } OK I am hoping that I did not include too much code. I would really appreciate any other comments about I could otherwise improve this code in any other ways also.

  • SQL join produces one result only

    - by Rami
    Can anyone please tell me why this result is generation only one results? taking in mind that everything is set right and the three tables are populated correctly, i took out the group_concat and it worked but of course with a php undefined index error! SELECT `songs`.`song_name`, `songs`.`add_date`, `songs`.`song_id`, `songs`.`song_picture`, group_concat(DISTINCT artists.artist_name) as artist_name FROM (`songs`) JOIN `mtm_songs_artists` ON `songs`.`song_id` = `mtm_songs_artists`.`song_id` JOIN `artists` ON `artists`.`artist_id` = `mtm_songs_artists`.`artist_id` ORDER BY `songs`.`song_id` DESC LIMIT 10 so i'm guessing it's something related to group_concat. best regards, Rami

  • Copy Rows in a One to Many with LINQ (2 SQL)

    - by Refracted Paladin
    I have a table that stores a bunch of diagnosis for a single plan. When the users create a new plan I need to copy over all existing diagnosis's as well. I had thought to try the below but this is obviously not correct. I am guessing that I will need to loop through my oldDiagnosis part, but how? Thanks! My Attempt so far... public static void CopyPlanDiagnosis(int newPlanID, int oldPlanID) { using (var context = McpDataContext.Create()) { var oldDiagnosis = from planDiagnosi in context.tblPlanDiagnosis where planDiagnosi.PlanID == oldPlanID select planDiagnosi; var newDiagnosis = new tblPlanDiagnosi { PlanID = newPlanID, DiagnosisCueID = oldDiagnosis.DiagnosisCueID, DiagnosisOther = oldDiagnosis.DiagnosisOther, AdditionalInfo = oldDiagnosis.AdditionalInfo, rowguid = Guid.NewGuid() }; context.tblPlanDiagnosis.InsertOnSubmit(newDiagnosis); context.SubmitChanges(); } }

  • SQL: GROUP BY after JOIN without overriding rows?

    - by krismeld
    I have a table of basketball leagues, a table af teams and a table of players like this: LEAGUES ID | NAME | ------------------ 1 | NBA | 2 | ABA | TEAMS: ID | NAME | LEAGUE_ID ------------------------------ 20 | BULLS | 1 21 | KNICKS | 2 PLAYERS: ID | TEAM_ID | FIRST_NAME | LAST_NAME | --------------------------------------------- 1 | 21 | John | Starks | 2 | 21 | Patrick | Ewing | Given a League ID, I would like to retrieve all the players' names and their team ID from all the teams in that league, so I do this: SELECT t.id AS team_id, p.id AS player_id, p.first_name, p.last_name FROM teams AS t JOIN players AS p ON p.team_id = t.id WHERE t.league_id = 1 which returns: [0] => stdClass Object ( [team_id] => 21 [player_id] => 1 [first_name] => John [last_name] => Starks ) [1] => stdClass Object ( [team_id] => 21 [player_id] => 2 [first_name] => Patrick [last_name] => Ewing ) + around 500 more objects... Since I will use this result to populate a dropdown menu for each team containing each team's list of players, I would like to group my result by team ID, so the loop to create these dropdowns will only have to cycle through each team ID instead of all 500+ players each time. But when I use the GROUP BY like this: SELECT t.id AS team_id, p.id AS player_id, p.first_name, p.last_name FROM teams AS t JOIN players AS p ON p.team_id = t.id WHERE t.league_id = 1 GROUP BY t.id it only returns one player from each team like this, overriding all the other players on the same team because of the use of the same column names. [0] => stdClass Object ( [team_id] => 21 [player_id] => 2 [first_name] => Patrick [last_name] => Ewing ) [1] => stdClass Object ( [team_id] => 22 [player_id] => 31 [first_name] => Shawn [last_name] => Kemp ) etc... I would like to return something like this: [0] => stdClass Object ( [team_id] => 2 [player_id1] => 1 [first_name1] => John [last_name1] => Starks [player_id2] => 2 [first_name2] => Patrick [last_name2] => Ewing +10 more players from this team... ) +25 more teams... Is it possible somehow?

  • Good way to format decimal in SQL Server

    - by Brad
    We store a decimal(9,8) in our database. It can have any number of places after the decimal point (well, no more than 8). I am frustrated because I want to display it as human-readable text as part of a larger string created on the server. I want as many decimals to the right of the decimal point as are non-zero, for example: 0.05 0.12345 3.14159265 Are all good If I do CAST(d AS varchar(50)) I get formatting like: 0.05000000 0.12345000 3.14159265 I get similar output if I cast/convert to a float or other type before casting to a varchar. I know how to do a fixed number of decimal places, such as: 0.050 0.123 3.142 But that is not what I want. Yes, I know I can do this through complicated string manipulation (REPLACE, etc), there should be a good way to do it.
