Problem In C# Code Behind And With SQL String Date And The Between Statement
May 13, 2008
Hi
I have a problem to search between two dates, if I use Convert(varchar(10),ContactCreateDate,105) in a single textbow and for a single search date it is okay, but when I use the Convert(varchar(10),ContactCreateDate,105) against two textboxes it did't function.
Can anybody help me ?
MY codeif (TBContactSearchDateStart.Text.Length > 0 && TBContactSearchDateEnd.Text.Length > 0)
{
strWhere += " AND Convert(varchar(10),ContactCreateDate,105) BETWEEN '%" + TBContactSearchDateStart.Text + "%' AND '%" + TBContactSearchDateEnd.Text + "%'";
My source file is showing column 10 as string. My destination table is datetime. I am using the derived transformation with a conditional statement. How do I convert the value from string to date. Everywhere I try the (DT_DATE) I get an error.
HiI am using SQL 2005, VB 2005I am trying to insert a record using parameters using the following code as per MotLey suggestion and it works finestring insertSQL; insertSQL = "INSERT INTO Issue(ProjectID, TypeofEntryID, PriorityID ,Title, Area) VALUES (@ProjectID, @TypeofEntryID, @PriorityID ,@Title, @Area)"; cmdInsert SqlCommand; cmdInsert=new SqlCommand(insertSQL,conn); cmdInsert.Parameters.Add("@ProjectID",SqlDbType.Varchar).Value=ProjectID.Text; My query is how to detail with dates my previous code wasinsertSQL += "convert(datetime,'" + DateTime.Now.ToString("dd/MM/yy") + "',3), '";I tried the code below but the record doesn't save?string date = DateTime.Now.ToString("dd/MM/yy"); insertSQL = "INSERT INTO WorkFlow(IssueID, TaskID, TaskDone, Date ,StaffID) VALUES (@IDIssue, @IDTask, @TaskDone, convert(DateTime,@Date,3),@IDStaff)"; cmdInsert.Parameters.Add("IDIssue", SqlDbType.Int).Value = IDIssue.ToString();cmdInsert.Parameters.Add("IDTask",SqlDbType.Int).Value = IDTask.Text;cmdInsert.Parameters.Add("TaskDone",SqlDbType.VarChar).Value = TaskDoneTxtbox.Text;cmdInsert.Parameters.Add("Date",SqlDbType.DateTime).Value = date;cmdInsert.Parameters.Add("IDStaff",SqlDbType.Int).Value = IDStaff.Text;Could someone point to me in the right direction?Thanks in advance
I asked this question below, but the answer was that the conversion will take place automatically, but I can't get that to happen. I have a flat file with an 8 position field that I identify as string (and I also tried date) that is yyyymmdd and it needs to go into the database field that is datetime format. IS there something I am doing wrong with the definition of it, or do I need to add some kind of conversion, and if so, what and how would that be done. I'm a dts Sql2000 expert, but the SSIS thing is driving me crazy. I have a ton of dts' to convert and the migration tool doesn't work because there are a lot of active X scripts in them. thanks for your help. Boston Rose
I have a table in which a date value is stored as varchar.some of these values are stored ina dd/mm/yyyy format and other values are stored in a yyyy-mm-dd format..Now I wish to retrieve some data by querying between two dates. However I need to convert the varchar date value to datetime in order to do this but since the date value is in two different formats, the following doesn't work.
select date_value from my_table where CONVERT(DATETIME, date_value, 103) between @date1 and @date2
How can you convert the date value to datetime when its stored in mutiple formats. I can't change the table itself as I dont have admin privelages.
I currently have the following code in my designer file <asp:SqlDataSource ID="SqlDataSource1" Runat="server" SelectCommand="select Site_name, system_id, ASP_Archive, sitetimes,HPOV_ROC, UPPER(CircuitType) as CircuitType, QwestCircuit_ID, SiteConfig,Site_Nat, PVC_VCI from tblASPCustomerWan order by Asp_Archive asc" UpdateCommand="UPDATE tblASPCustomerWan SET [Site_name] = @Site_name, [system_id] = @system_id, [ASP_Archive] = @ASP_Archive, [sitetimes] = @sitetimes, [HPOV_ROC] = @HPOV_ROC, [CircuitType] = @CircuitType, [QwestCircuit_ID] = @QwestCircuit_ID, [SiteConfig]= @SiteConfig, [Site_Nat]=@Site_Nat,[PVC_VCI]=@PVC_VCI" ConnectionString="server=localhost;Trusted_Connection=yes;uid=portal_user;pwd=Cr@zyP@55w0rd;database=CusPortal_Staging" /> I would like the change the connection so it takes it value from System.Configuration.ConfigurationManager.AppSettings("appStrConnection"), how can i do that??
How do I convert for example, a value comming from C# app "TextboxGBDataDeleted" to int column GBdatadeleted? I have a RangeValidator on this textbox to accept only numbers. I don't want to write C# code. I woul prefer to do this is SQL. Thank you.
i was able to succesfully configure my remote server over the internet and tried using express edition to connect to my remote server and everything when successful.
is there a way to copy that connection string used to connect to my remote server so as i wanted to create a project in vb using that connection string..
where can i find the connection string code used for my connection remotely ..
Every time I move my project from my computer to the testing server I have to change the connection string references in the aspx side and in my code behind. For the code behind I declared the SqlConnection string at the top of the code-behind page for both connection strings and comment out the one not in use. Obviously I then comment out the string not in use in the WebConfig as well. Being superlatively lazy I always look for the easiest and quickest way to do most anything - connection strings included. Having to comment out strings twice brought rise to the question of whether I can refer to the connection string in the web.config file from the code-behind page. I'm sure it can be done, and I did a good amount of hunting around, but I couldn't find any examples of code that would do that. Currently, as I said above, I have two connection strings declared at the top of my code-behind. Here's an example of one:Private sqlConn As New SqlConnection("Data Source=DATABASESERVER;Initial Catalog=DATABASE;User ID=USER;Password=PASSWORD") Then, I just use sqlConn as usual in my binding without having to "dim" it in every sub:sdaPersonnel = New SqlDataAdapter(strSqlPersonnel, sqlConn) Then there's the SqlConnections set up by the wizard on the aspx side:<asp:SqlDataSource ID="sqlDataSourcePayrollCompany" Runat="Server" ConnectionString="<%$ ConnectionStrings:DATABASECONNECTIONSTRING %>" ...> And for the connection in the web.config:<add name="DATABASECONNECTIONSTRING" connectionString="Data Source=DATABASESERVER;Initial Catalog=DATABASE;User ID=USER;Password=PASSWORD" providerName="System.Data.SqlClient" /> So, what would be the code in the code-behind page to refer to the connection string in the web.config file? Thanks!

Now I need to split the above record into 6 Fields and populate in my local DB I know i could use any .NET Language and accomplish this. But Iam limited to using SSIS/T-SQL Proc's

I'm trying to create a form that allows someone to find an address from a postal code search in the database. My query works exactly as I’d like in query builder using the following select:
Select [FIELD_LIST] from addresses WHETE POSTCODE LIKE ‘%’+@POSTCODE+’%’
I then pass the user entered post code to the select statement which is executed. However, I’m getting some odd behaviour. Assuming there is an address in the database with the post code “LS11 0ES”...
If I search for LS11, nothing is returned;
If I search for LS11%, nothing is returned;
If I search for %LS11%, nothing is returned;
If I search for %LS11%%, the data is returned.
If I search for %LS%1%%, the data is returned (as is LS21 0ES etc. etc.).
However, I want the user to be able to enter shorter search strings and it to pull all the data back out, so they can enter a substring such as LS and it will pull out all the data without the users needing to enter the full pattern of % symbols.
If I go into query builder (in visual web developer) and enter just “LS” it works as I’d want, but not when pulled from a web page.
Hello i constructed the following query in SQL management studio and it runs fine, exactly how i want it to. However when i run it in my code behind i get the error: 'Too many characters in character literal' I desperatly need to use this query exactly how it displays in the mangement tool - why wont it work the same in my code behind? (I am using c# in my code behind and binding the results of the query to a gridview) Regards "SELECT DISTINCT (dbo.AuthorList(publicationID))+ ';' + ISNULL(' Editor: '+Publication.editor, '')+ '' + ISNULL(' "'+Publication.title+'"', '')+ '' + ISNULL(' Book: "'+Publication.booktitle+'"', '')+ '' + ISNULL(' '+Publication.type, '')+ '' + ISNULL(' '+Publication.journal, '')+ '' + ISNULL(' Series: '+Publication.series+'.', '')+ '' + ISNULL(' '+Publication.school, '')+ '' + ISNULL(' '+Publication.institution, '')+ '' + ISNULL(' '+Publication.organisation, '')+ '' + ISNULL(' '+Publication.month, '')+ '' + ISNULL(' ('+convert(nvarchar, Publication.year)+')', '')+ '' + ISNULL(' '+Publication.publisher, '')+ '' + ISNULL(' '+Publication.address+'.', '')+ '' + ISNULL(' '+Publication.howpublished, '')+ '' + ISNULL(' Ed: '+convert(nvarchar, Publication.edition)+'.', '')+ '' + ISNULL(' '+Publication.note, '')+ '' + ISNULL(' Vol:'+Publication.volume+'.', '')+ '' + ISNULL(' No:'+Publication.number+'.', '')+ '' + ISNULL(' Pages:'+Publication.pages+'.', '')+ '' + ISNULL(' Chapter:'+Publication.chapter+'.', '') AS SingleColumn, Publication.publicationID FROM Publication;"
I have coded an alter statement for adding a column to a temp table inside an sp,but it skips the alter statement while executing the sp! This happens even if I run the same code on query analyzer too. If I use 'GO' statement before the alter command,then it works fine on Query Analyzer.But, I can't use 'GO' in an sp. I am using the sa account. Any ideas on how to fix this?? Thanks. Di.
I wanted to determine the date of the last Saturday with respect to the current date so that I could create a temp table with date ranges numbered 1-4 e.g. up to that date, post link below: URL....I now want to make this function that any time I pass it a day name (mon-sun) it will calculate the date of the previous (mon-sun) with respect to the current day. This date will then be the last date in my range.
So for example I run the function and pass it 'Friday' then I want last date in my range to be the 25th of July (today being Friday so need last Friday), I pass it Thursday I want it to give me the 31st of July etc. I need last date of that date but if I call Friday and today is Friday then need last friday; I think this is the trickier part of it.
This calculation I would image would need to use a combination of datediff dateadd etc. but really don't know how to do this dynamically.Currently I have a function that I pass the last date for the date range I want for my weeks range, I also give it the numbere of weeks I want in my range and also pass the date from the query that I want to know what week range it is in.
ALTER FUNCTION [dbo].[daterangeweeknumber] ( -- Add the parameters for the function here @refDate datetime, @Weeks INT, @lastdate datetime
]code]....
But now I want just to be able to pass it the day name - in this instance would be 'Wednesday' and want it to return date ranges with last date as Wed the 30th of July. Reason I want to use day name is that people will be running these reports on a certain day - for instance on Wednesday and last day to be Monday - and this will mean they do not have to keep changing the date in the call to function.
Hi you all, In abc.aspx, I use a GridView and a SqlDataSource with a SelectCommand. The GridView's DataSourceID is the SqlDataSource. In abc.aspx.cs, I would like to use an IF statement in which if a criterion is not satistied then I will use the SqlDataSource with another SelectCommand string. Unfortunately, I have yet to know how to write code lines in order to do that with the SqlDataSource. Plz help me out!
have a problem ... I tried to test my statement in QA as it returns no dataset ,it gives me empty columns in return,I though it will return all the columns and some records of (lmeyer) as the current user ,who logged in on windows auth,but it return only the columns,is that means my query analyser cannot read the login1 ,column which has the username as (lmeyer)
select * from tstudents where (login1='@param1')
if not what could me wrong in my code ,because I get no response to the sql server
Public Function login(ByVal login1 as string) as dataset
Dim myconnection as new sqlconnection("server=G103-TT03;database=CampusLANDB;Trusted_Connection=yes") dim mycommand as new sqlcommand ("Select * from tStudents Where login1 = @param1",myconnection) mycommand.parameters.add(new SQLClient.SqlParameter("@param1",login1))
dim DS as new dataset()
try myconnection.open
dim adpt as new sqldataadapter adpt.selectcommand = mycommand adpt.fill(DS,"tStudents")
catch ex as exception throw new exception(ex.message) return nothing finally myconnection.close end try
try mydatagrid.datasource=DS.Tables("tStudents") mydatagrid.databind() catch ex as exception errorlabel.text=ex.message end try
I am new to SQL; the following code is supposed find comments that are not null on one day before the studydate.
SELECTp.PatientID,P.LastName,P.FirstName,P.BirthTime,s.StudyDate,s.Modality,s.Comments FROMStudies s INNER JOIN Patients p ON s.PatientID = p.PatientID WHEREs.Comments IS NOT NULL AND s.StudyDate >= CONVERT(char,DATEADD(day, -12, GETDATE()),101) AND s.StudyDate < CONVERT(char,DATEADD(day, -11, GETDATE()),101)
Is there a problem with this code? I expect there is because when I ran the query it didn't return any results even though I am positive there are comments in the database one day before the studydates.

I am trying to understand creating SQL Server projects and managed code. So I created a C# SQL Server Database project and named it "CSharpSqlServerProject1" and followed the steps in the following "How to: " from the Help files:
"How to: Create and Run a CLR SQL Server Stored Procedure "
I used the exact code in this "How to: " for creating a SQL Server managed code stored procedure (see below) in C#. However it didn't even compile! When I went to build the code I got the following error message:
"Error 1 Target string size is too small to represent the XML instance CSharpSqlServerProject1"
It does not give a line number or any further information! Since this is a Microsoft example I'm following I figure others must have run into this too. I can't figure out how to fix it!
Here's the code as copied directly from the howto:
using System.Data.SqlClient; using System.Data.SqlTypes; using Microsoft.SqlServer.Server;

I'm trying to add a 'change password' control to my site and seem to be having some issues. I have code that works if I statically define what user is displayed on the form, but I cant get it to detect the 'authenticated' user and show them the reset for for that ID.If I take the "+ myid" out of the select statement and just define the username statically the form works properly. Error:System.Data.SqlClient.SqlException: The column prefix 'System.Security.Principal' does not match with a table name or alias name used in the query. Here's a piece of the code that is supposed to detect the current logged in user. However, it gives the error. (some of the code may be redundant but its not causing issues that I can tell) public void InitPage() { IPrincipal p = HttpContext.Current.User; String myid = HttpContext.Current.User.ToString(); SqlServer sqlServer = new SqlServer(Util.SqlConnectionString()); DataTable dt; SqlConnection cnn = new SqlConnection(ConfigurationManager.ConnectionStrings["myconnection"].ConnectionString); SqlDataAdapter cmd1 = new SqlDataAdapter("select * from USER WHERE USER_NAME = "+ myid, cnn); DataTable UIDtable = new DataTable(); cmd1.Fill(UIDtable); User_Id.Value = UIDtable.Rows[0]["ID"].ToString(); dt = sqlServer.USER_SELECT(Util.SiteURL(Request.QueryString["Pg"].ToString()), User_Id.Value);
the following is my TSQL command of a job(after passing databaseName, I don't want multiple steps, just with 1 step) --=================================== BACKUP DATABASE ABC To Backup_ABC_1 with init, name = 'Backup of 1(M, W, F ) Job_ABC_1Mon' go backup log ABC with truncate_only go print 'shrinkdatabase begin-- ' dbcc checkdb(ABC) go dbcc shrinkdatabase(ABC, 10)
Issue: with 3 'go' inside the whole line, execution failed. after replace 'go' with 'begin' and 'end' for each sql statemet, the execution works. Someone could explain why 'go' as a batch does not work in this situation?
also, is this a good practice to 1. truncate_only 2. dbcc checkdb 3. shrinkdatabase after a daily backup?
