I have a linked db in my sql database and one of the fields I am trying to query is an array. Is there a way to only select 1 element of the array instead of all the values. When I do the select in t-sql for the linked server I get a semi-colon list of values.
The linked server db has a function called pro_element(fieldname,1,1) which will return 1 array element, but t-sql obviously won't recognize this. Is there something similar? Or can I tell t-sql to pass this to the DB even if it doesn't know the command?
I created a custom function that accepts an array of strings as a input. I need to pass several fields from the dataset to this function as an array. How can I do this?
I using Visual Web Designer Express (with Visual Basic), with a SQL Server 2000 database. I have a prototype application running satisfactorily using code that builds queries, but I'm now trying to rebuild the application "properly" using three-tier architecture. I have been following the principles of Scott Mitchell's tutorials. I have created an database .xsd with a table adaptor, and replaced the rather grotty query-building code in the business layer with better code referencing the table adaptor. Thus where the first version had code: - Dim queryString As String = "SELECT * FROM NZGDB_User WHERE USRid = '" & Userid & "'" Dim message As String = "" Dim Found As Boolean = False Try Using connection As New SqlConnection(GDB_AppSettings.Connection) Dim command As New SqlCommand(queryString, connection) connection.Open() Dim reader As SqlDataReader = command.ExecuteReader() If reader.Read() Then Found = True _USRid = reader("USRid") _USRPassword = reader("USRPassword") _USREmail = reader("USREmail") _USRTitle = reader("USRTitle") _USRName = reader("USRName") _USRRole = reader("USRRole") If IsDBNull(reader("USRAgreedConditions")) = False Then _USRAgreedConditions = reader("USRAgreedConditions") End If End If reader.Close() End Using Catch ex As Exception If Left(Err.Description, 68) = "An error has occurred while establishing a connection to the server." Then Return "Cannot open database to logon" Else Return Err.Description End If End Try the new version is much more elegant: - Dim taUser As New NZGDBTableAdapters.NZGDB_UserTableAdapter() Dim tbUser As NZGDB.NZGDB_UserDataTable = taUser.GetUserByUserid(userid) If tbUser.Count <> 1 Then ' Anything other than 0 or 1 should be impossible Return "User not found" End If Dim trUser As NZGDB.NZGDB_UserRow = tbUser(0) _USRid = userid _USRPassword = password _USREmail = trUser.USREmail _USRTitle = trUser.USRTitle _USRName = trUser.USRName _USRRole = trUser.USRRole _USRAgreedConditions = trUser.USRAgreedConditions However, there is a problem. The database field USRAgreedConditions is a Datetime field that can be null. The new version works perfectly when it is NOT null, but throws an exception: - System.Data.StrongTypingException was unhandled by user code Message="The value for column 'USRAgreedConditions' in table 'NZGDB_User' is DBNull." Source="App_Code.wt2vzoc1" .... There is no point in writing: - If Not IsDBNull(trUser.USRAgreedConditions) Then _USRAgreedConditions = trUser.USRAgreedConditions End Ifbecause the exception occurs within the automatically-created code in the data access layer. I tried changing the Nullvalue property of the field USRAgreedConditions in the table adaptor, but the only valid option is (Throw Exception) unless the field is a String. Of course USRAgreedConditions is a Datetime field, so I can't change the property. It seems that my only options are: -1. To stick with the old query-building code. But this doesn't give me the advantages of a proper 3-tier architecture2. To change the generated code in wt2vzoc. This MUST be a bad idea - surely I should leave this code untouched. Besides, what if the table adaptor has to be regenerated when I change the table design?3. Code a Try block within the business layer: - Try _USRAgreedConditions = trUser.USRAgreedConditions Catch ex As Exception _USRAgreedConditions = Nothing End Try This seems to work OK, but seems less elegant than the original code in the old version: - If IsDBNull(reader("USRAgreedConditions")) = False Then _USRAgreedConditions = reader("USRAgreedConditions") End IfIs there a better way?
I have a stored procedure that has a paramter that accepts a string of values. At the user interface, I use a StringBuilder to concatenate the values (2,4,34,35,etc.) I would send these value to the stored procedure. The problem is that the stored procedure doesn't allow it to be query with the parameter because the Fieldname, "Officer_UID" is an integer data type, which can't be query against parameter string type. What would I need to do to convert it to an Integer array? @OfficerIDs as varchar(200) Select Officer_UID From Officers Where Officer_UID in (@OfficerIDs) Thanks
I have just started using SQL Server reporting services and am stuck with creating subreports.
I have a added a sub report to the main report. When I right click on the sub report, go to properties -> Parameters, and click on the dropdown for Parameter Value, I see all Sum and Count fields but not the data fields.
For example, In the dropdownlist for the Parameter value, I see Sum(Fields!TASK_ID.Value, "AppTest"), Count(Fields!TASK_NAME.Value, "CammpTest") but not Fields!TASK_NAME.Value, Fields!TASK_ID.Value which are the fields retrieved from the dataset assigned to the subreport.
When I manually change the parameter value to Fields!TASK_ID.Value, and try to preview the report, I get Error: Subreport could not be shown. I have no idea what the underlying issue is but am guessing that it's because the field - Fields!TASK_ID.Value is not in the dropdown but am trying to link the main report and sub report with this field.
Am I missing something here? Any help is appreciated.
How can I create a Table whose one field will be 'tableid INT IDENTITY(1,1)' and other fields will be the fields from the table "ashu". can this be possible in SQL Server without explicitly writing the"ashu" table's fields name.

I am using MS SQL 2012. I have a table that contains all the data that I need, but I need to summarize the data and also add up decimal fields while at it. Then I need a total of those added decimal fields. My data is like this:
I have Providers, a unique ID that Providers will have multiples of, and then decimal fields. Here are my fields:
I would like to search a table for a phrase, or for a partial phrase,eg on table product - for name or description, or name + descprition.How does one say select * from product where name + description like%phrase%or contains phraseCurrently I can get where name, or where descriotion like %phrase%,eg, where name like krups, or where description like coffee makerBut if I search for where name like %krups coffee maker% i get noresults. krups is in the name field, coffee maker is in thedescription field.Thanks,-M
Pardon me if this question is too elementary. I am trying to create a trigger that will cause certain datafields to be updated with values from other data fields in the same row when a certain column, created specifically to fire the trigger, is updated. The purpose of this is to reduce data entry by field personnel.I think I have the create trigger statement correct, but I'm a little confused on the update statement.
In a nutshell, how can I write something like: UPDATE "TABLENAME" SET DATAFIELD1 = DATAFIELD2 WHERE RECORDNUMBER = (THE SAME RECORD NUMBER)
I do know that I have to ensure that sp_dboption Recursive Triggers value is set to false, thanks.
I have a list of items in one table and a field (pageName) in another table that may contain one of the aforementioned items somewhere within that field. There is no fixed position within the field where the itemNo may be so I can't just use SUBSTRING(pageName,2,5) in(select itemNo from tblItem).
Logically, it's like I need to combine IN and LIKE: select pageName where pageName LIKE IN %select itemNo from tblitemNo%..LIKE can only handle one comparison string.
Hi people My users are having troubles with link to default drillthrough report when reports are exported to excel (they REALLY don't like this behavior ), so I decided set all of them disabled in report model, this work fine, but calculated field in reports has this drillthrough link.
Let me show you the situation. Entity Product has an UnitaryCost field, I set the EnableDrillthrough Property in False so when I export a report with this field, no link is shown.
But if I create in the report a calculated field Round(UnitaryCost) this field has a Drillthrough Link
Is this the standard and expected behavior? or its simply a BUG?
Have I done something wrong in my model? and in this case, How I can correct this?

I have two CheckBoxList controls. One CheckBoxList is a group of area codes as they apply to our customers, and the second CheckBoxList is a group of categories of those customers. The code below works fine with either CheckBoxList as a standalone (this code applies to the Area Codes selection), but what I need is the VB code to combine the choices a user makes in both CheckBoxLists. Is this where parameterized SQL comes into play? Or can I/should I use an array statement to combine both CheckBoxList choices? Sometimes a user will select nothing in one CBL and a few choices in the other, or vice versa, or a handful of choices in both CBLs, so that they might want only customers in, say two area codes and then only the selected categories of those area codes. Need help on this one, thanks...Protected Sub btn_CustomerSearchCombine_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btn_CustomerSearchCombine.Click Dim ACSelections As Boolean = False Dim ACItem As ListItem For Each ACItem In cbl_CustomerSearchAREA.Items If ACItem.Selected Then ACSelections = True End If Next If ACSelections = True Then Dim ACSqlString As String ACSqlString = "SELECT Customers.CustomerID, Customers.CustomerName, Customers.CategoryID, Customers.EstHours, Customers.Locality, Categories.Category FROM Customers INNER JOIN Categories ON Customers.CategoryID = Categories.CategoryID WHERE " For Each ACItem In cbl_CustomerSearchAREA.Items If ACItem.Selected Then ACSqlString &= "Customers.AreaCodeID = '" & ACItem.Value & "' OR " End If Next ACSqlString = Left(ACSqlString, Len(ACSqlString) - 4) ACSqlString &= "ORDER By Customers.CustomerName" sql_CustomerSearchGrid.SelectCommand = ACSqlString End IfEnd Sub

My Issue is the next thing: I have a table filled with contracts I have Stoc that checks if contract has expired If I start the Stoc I must give it the contractnumber with it like: SP_expired 8
This works fine but now I want that the Stoc checks all the contracts by just starting the Stoc.
I don't really know how to do this, I have thinking about using an array. But don't have an idea where to start....
Please excuse me if this is the wrong forum. I hope your combined genius will be able to point me in the right direction.

hi guys im having some problems with arrays as parameter what i want to do is pass a array of comma separated values i.e 12,24,36 and use the in(@parameter) but it doesnt work
i've found some solutions, like ALTER PROCEDURE [dbo].[GetLawyers] ( @LawyerTypeIDs VARCHAR(100) AS
DECLARE @SQL VARCHAR(2000)
SET @SQL = 'SELECT * FROM [dbo].[TB_VALOR_BANCOS] WHERE [PARCELAS] IN (' + @LawyerTypeIDs + ')' EXECUTE (@SQL)
but in my case doesnt work.
here is a part of my code SELECT * FROM ( SELECT *, ROW_NUMBER() OVER (PARTITION BY cod_banco ORDER BY coeficiente asc) AS RecID FROM tb_valor_bancos where (1 = CASE WHEN @TABELA IS NULL THEN 1 ELSE CASE WHEN TABELA = @TABELA THEN 1 ELSE 0 END END ) AND (1 = CASE WHEN @PARCELAS IS NULL THEN 1 ELSE CASE WHEN PARCELAS in(@PARCELAS) THEN 1 ELSE 0 END END ) ...
i know there is a way to pass the array into a table but it doesnt work too
I have seen several examples explaining the fact that a tablecontaining a field for each day of the week is for the most part anarray. An specific example is where data representing worked hours isstored in a table.CREATE TABLE [hoursWorked] ([id] [int] NOT NULL ,[location_id] [tinyint] NOT NULL,[sunday] [int] NULL ,[monday] [int] NULL ,[tuesday] [int] NULL ,[wednesday] [int] NULL ,[thursday] [int] NULL ,[friday] [int] NULL ,[saturday] [int] NULL)I had to work with a table with a similar structure about 7 years agoand I remember that writing code against the table was pretty close toHell on earth.I am now looking at a table that is similar in nature - but different.CREATE TABLE [blah] ([concat_1_id] [int] NOT NULL ,[concat_2_id] [int] NOT NULL ,[code_1] [varchar] (30) NOT NULL ,[code_2] [varchar] (20) NULL ,[code_3] [varchar] (20) NULL ,[some_flg] [char] (1) NOT NULL) ON [PRIMARY]The value for code_2 and code_3 will be dependently null and they willrepresent similar data in both records (i.e. the value "abc" can existin both fields) . For example if code_2 contains data then code_3 willprobably not contain data.I do not think that this is an array. But with so many rows wherecode_2 and code_3 will be NULL something just does not feel right.I will appreciate your input.

This data was collected using Export Import Wizard from flatfile and put it in one column. I want to split the header and the detail into different table and map each column separated by ; to a proper field. For this work I should check every column separated by ; with CHARINDEX function but I have to write the TSQL as much as the count of ;. It would be better if we can use array to simplify the code.
Can we use array in Transact SQL ? since I have no clue referring to SQLBOL. Thanks in advance.
