I am having problems setting the value of a variable in a SQL String
that I have to create dynamically in my procedure. The code that I
currently have is as follows:
set @sqlStatement='Set @compare_string=' + '(Select ' +
@group_column_list_mod + ' from ' + @Tbl_Name + '_Sorted' + ' where
Identity_Column=' + ltrim(rtrim(str(@loop_counter))) + ')'
exec(@sqlStatement)
The error message that I get is as follows:
Must declare the variable '@compare_string'.
Here @compare_string has already been declared in the procedure and I
don't have a problem using the variable anywhere else but this SQL
Statement (when called using the EXEC function).
I am not sure why SQL Server can't see the variable declared when used
in a string in conjunction with EXEC. Is this a syntax issue? Any help
on this issue would be greatly appreciated!
ok, I am on Day 2 of being brain dead.I have a database with a table with 2 varchar(25) columns I have a btton click event that gets the value of the userName, and a text box.I NEED to insert a new row in a sql database, with the 2 variables.Ive used a sqldatasource object, and tried to midify the insert parameters, tried to set it at the button click event, and NOTHING is working. Anyone have a good source for sql 101/ASP.Net/Braindead where I can find this out, or better yet, give me an example. this is what I got <%@ Page Language="C#" %><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><script runat="server"> protected void runit_Click(object sender, EventArgs e) { //SqlDataSource ID = "InsertExtraInfo".Insert(); //SqlDataSource1.Insert(); } protected void Button1_Click1(object sender, EventArgs e) { SqlDataSource newsql; newsql.InsertParameters.Add("@name", "Dan"); newsql.InsertParameters.Add("@color", "rose"); String t_c = "purple"; string tempname = Page.User.Identity.Name; Label1.Text = tempname; Label2.Text = t_c; newsql.Insert(); }</script><html xmlns="http://www.w3.org/1999/xhtml" ><head runat="server"> <title>mini update</title></head><body> <form id="form1" runat="server"> name<asp:TextBox ID="name" runat="server" OnTextChanged="TextBox2_TextChanged"></asp:TextBox><br /> color <asp:TextBox ID="color" runat="server"></asp:TextBox><br /> <br /> <asp:Button ID="Button1" runat="server" OnClick="Button1_Click1" Text="Button" /> <br /> set lable =><asp:Label ID="Label1" runat="server" Text="Label" Width="135px" Visible="False"></asp:Label><br /> Lable 2 => <asp:Label ID="Label2" runat="server" Text="Label"></asp:Label><br /> Usernmae=><asp:LoginName ID="LoginName1" runat="server" /> <br /> <br /> <br /> <br /> <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConflictDetection="CompareAllValues" ConnectionString="<%$ ConnectionStrings:newstring %>" DeleteCommand="DELETE FROM [favcolor] WHERE [name] = @original_name AND [color] = @original_color" InsertCommand="INSERT INTO [favcolor] ([name], [color]) VALUES (@name, @color)" OldValuesParameterFormatString="original_{0}" SelectCommand="SELECT [name], [color] FROM [favcolor]" UpdateCommand="UPDATE [favcolor] SET [color] = @color WHERE [name] = @original_name AND [color] = @original_color"> <DeleteParameters> <asp:Parameter Name="original_name" Type="String" /> <asp:Parameter Name="original_color" Type="String" /> </DeleteParameters> <UpdateParameters> <asp:Parameter Name="color" Type="String" /> <asp:Parameter Name="original_name" Type="String" /> <asp:Parameter Name="original_color" Type="String" /> </UpdateParameters> <InsertParameters> <asp:InsertParameter("@name", "Dan", Type="String" /> <asp:InsertParameter("@color", "rose") Type="String"/> </InsertParameters> </asp:SqlDataSource> <asp:GridView ID="GridView1" runat="server" AllowPaging="True" AllowSorting="True" AutoGenerateColumns="False" DataKeyNames="name" DataSourceID="SqlDataSource1"> <Columns> <asp:CommandField ShowDeleteButton="True" ShowEditButton="True" ShowSelectButton="True" /> <asp:BoundField DataField="color" HeaderText="color" SortExpression="color" /> <asp:BoundField DataField="name" HeaderText="name" ReadOnly="True" SortExpression="name" /> </Columns> </asp:GridView> </form></body></html>
Hi, I have this query basically im trying to set the @db to the current database depending on the quarter. This will be used in a package to change the database that the package will use.
DECLARE @db nVarchar(4000) SET @db = N'TESTDB' + RIGHT(DATEPART(yy, GETDATE()), 2) + '_' + CASE WHEN DATEPART(m, GETDATE()) IN ('11', '12', '1') THEN 'Q1' ELSE CASE WHEN DATEPART(m, GETDATE()) IN ('2', '3', '4') THEN 'Q2' ELSE CASE WHEN DATEPART(m, GETDATE()) IN ('5', '6', '7') THEN 'Q3' ELSE CASE WHEN DATEPART(m, GETDATE()) IN ('8', '9', '10') THEN 'Q4' END END END END EXECUTE sp_executesql @db, N'@level tinyint', @level = 35
I get the error Incorrect Syntax near 'TESTDB04_Q3'.
I am trying to set the variables value through Execute SQL task and create directory through the FileSystemTask by setting the user variable as source. The User variable has the Directory path to create the directory, but when i set the source as the user variable it complains that its value is empty.
Execute SQL TAsk happens to work correctly when i check the watch window the user variable is set correctly . but value is not setting in the SSIS/Variable window Value.
What is wrong an what method should i use to set the variables value to create directory.
Hi, folks. As part of a larger bunch of code, I am trying to validate some user form input against a database...I've been picking apart code samples and have the following (currently not yet working) code to show for it. I find tons of complex examples out there RE the data controls, and I have those working. But I can't find any examples of just pulling a single record from a DB, sticking it in a variable, and then checking against that variable to get a boolean response. Anyway, here is the code. I am trying to check that a password field filled by the user matches the value located in the DB. I am not married to this code; if someone suggests a better way to do it rather than using a custom validator control, that's fine too:BEGIN CODE SNIPvoid Page_Load(object sender, EventArgs e) { Page.Validate(); SqlDataSource1.SelectCommand = "SELECT Password FROM aspnet_Membership WHERE aspnet_Membership.Email='" + emailID.Text + "'"; }
private void CustomValidator1_ServerValidate(object source, System.Web.UI.WebControls.ServerValidateEventArgs args) { //between this and the next comment is where I have to get the DB Password field value for the current record SqlCommand command = new SqlCommand("SELECT Password FROM aspnet_Membership WHERE aspnet_Membership.Email='" + emailID.Text + "'"); command.CommandType = CommandType.StoredProcedure; sqlConnection.Open(); reader=command.ExecuteReader(); string currentPasswordDb = reader.IsDBNull(reader.GetString("Password"))? null: reader["Password"].ToString(); args.IsValid = false; // Assume False { // Compare db entry against user's entry if (currentPasswordDb == currentPassword.Text) { args.IsValid = true; } } } END CODE SNIP The code above give me the following at runtime:Line 14: SqlCommand command = new SqlCommand("SELECT Password FROM aspnet_Membership WHERE aspnet_Membership.Email='" + emailID.Text + "'");Line 15: command.CommandType = CommandType.StoredProcedure;Line 16: sqlConnection.Open();Line 17: reader=command.ExecuteReader();Line 18: string currentPasswordDb = reader.IsDBNull(reader.GetString("Password"))? null: reader["Password"].ToString();Although I'm sure it won't be the last. I'm a former ASP classic developer, moving to c# and .Net. Any ideas?
I want to execute a BAT file using Execute Process task, where I want to select the file path (directory) dynamically using a variable whose value is set at runtime.
In simple terms I want to send a value to the "Executable" property dynamically
The For Loop will execute a stored procedure that passes a variable each time it loops. I need to set this variable, @FiscalWeek, equal to the variable @Counter. So the first time it loops, the counter will be 1, and the Fiscal Year would be set to 1. The next time it would be two, and so forth. Can I do this in the Expressions section of the For Loop? If so, what would the property be?
I want to be able to have a single select statment:
SELECT TOP 1 Call.JobNum, Call.CallID, Call.Company, Call.LastCallTime FROM ClientJob INNER JOIN Client ON ClientJob.ClientID = Client.ClientID INNER JOIN Call INNER JOIN Login ON Call.JobNum = Login.JobNum ON ClientJob.JobNum = Login.JobNum WHERE (Login.LoginID = 3) AND (Call.Status = 0) AND (DATEDIFF(hh, Call.LastCallTime, getdate()) > 10) ORDER BY Call.CallID
but with this select statment I also want to set a variable:
declare @variable int
SELECT TOP 1 Call.JobNum, @variable = Call.CallID, Call.Company, Call.LastCallTime FROM ClientJob INNER JOIN Client ON ClientJob.ClientID = Client.ClientID INNER JOIN Call INNER JOIN Login ON Call.JobNum = Login.JobNum ON ClientJob.JobNum = Login.JobNum WHERE (Login.LoginID = 3) AND (Call.Status = 0) AND (DATEDIFF(hh, Call.LastCallTime, getdate()) > 10) ORDER BY Call.CallID
Now SQL Server does not like this, can not set a variable in a multiple select statment. I NEED to do this all in one step if possible. Any suggestions?
declare @ret varchar(50) DECLARE @X SQL_VARIANT set @X=10 SET @ret=select SQL_VARIANT_PROPERTY(@X,'BaseType')
Just trying to assign the SQL_VARIANT_PROPERTY return value to @ret and it issues an error: Implicit conversion from data type sql_variant to varchar is not allowed. Use the CONVERT function to run this query.
But I don't want to convert I just want to assign the result to the variable.
what's confusding is that you can do this: if(select SQL_VARIANT_PROPERTY(@X,'BaseType'))='int'
I am having the wrost trouble with this today for some dumb reason... Please don't suggest any alternates; this is just a quick example, full code is more elaberate.
I'm in the process of creating a series of packages to do the ETL for a datawarehouse. As such, I've got quite a few DataFlow tasks scattered through them.
The problem I'm coming across is where the disk that the temp files (created during the processing) are put on is short of space (when compared to some of the data sets I'm copying around and noting that it's the System disk, not the "Data Drive").
To get around this, I found number of article scattered around that suggested using the BufferTempStoragePath property of the DataFlow tasks to redirect the temp files to somewhere else. This works fine for the tasks that I hard-code the new directory.
Noting the number of these tasks that I want to redirect, and also that the Dev environment will be different to the Production environment (and I have no control over the drive letters, paths, etc, in Prod), it was suggested that a package variable be created, assigned to the property and then said variable could be exposed via the Package Configuration file.
That's great as far as it goes, but I just cannot, for some reason, make it work.
The property in the DataFlow task is then set to: @BufferTempStoragePathValue.
When the package is executed, it logs the error message "The buffer manager cannot create a temporary storage file on any path in the BufferTempStoragePath property. There is an incorrect file name or no permission."
My question for the group is two-fold: 1) what am I doing wrong in the setup of the property/variable, and 2) what are the security permissions that are required for the (new) folder.
It's got to be something obvious, I just can't see what!
im using a Foreach ADO Enumerator in my SSIS Package, which iterate on a DataSet from a SQL Task.
I use the "Variable Mappings" on my Foreach Loop to retrieve the values into User-variables. But what i need is a way to combine a value from the DataSet with a User-variable and assign this new value to a new User-variable.
In a stored procedure that I'm fixing, there is a problem with assigning variable values inside a loop. The proc is using dynamic SQL and if statements to build all these statements, but I'm having to add a new variable value to it that is throwing it out of whack.
This is the current structure:
SET @MktNbr = 10
WHILE @MktNbr < 90
BEGIN
DECLARE@sqlstmt varchar(1000)
SET @Market = '0' + CONVERT(char(2),@MktNbr)
SET @sqlstmt = 'SELECT (columns) INTO dbo.table' + @Market + ' FROM #table WHERE marketcode = ''' + @Market + ''' IF @MktNbr = 50 BEGIN SET @MktNbr = 51 END ELSE IF @MktNbr = 51 BEGIN SET @MktNbr = 52 END ELSE IF @MktNbr = 52 BEGIN SET @MktNbr = 55 END ELSE IF @MktNbr = 55 BEGIN SET @MktNbr = 60 END ELSE BEGIN SET @MktNbr = @MktNbr + 10 END EXEC (@sqlstmt)
END
I'm probably having a blonde moment, but I'm trying to replace the if statements with this:
SET @MktNbr = CASE WHEN @MktNbr = 10 THEN 20 WHEN @MktNbr = 20 THEN 30 WHEN @MktNbr = 30 THEN 40 WHEN @MktNbr = 40 THEN 50 WHEN @MktNbr = 50 THEN 51 WHEN @MktNbr = 51 THEN 52 WHEN @MktNbr = 52 THEN 55 WHEN @MktNbr = 55 THEN 60 WHEN @MktNbr = 60 THEN 70 WHEN @MktNbr = 70 THEN 80 WHEN @MktNbr = 80 THEN 81 ELSE @MktNbr END
Clearly it's wrong because the proc bombs every time with a duplicate table error.
It has been suggested to me that I should hold these market values in an external table. This sounds reasonable but I'm ashamed to admit that I don't know how I'd implement that. Can someone maybe give me a nudge in the right direction?
I would like to set up a subscription that has two date parameters, I would like the end_date to be today and the start_date to be (today - 1 Month). The interface does not seem to support expressions?
I saw some documentation that said to use defaults in the report but that does not help because I may want multiple subscriptions with different params like 1 person may want (today - 2 months) as the start date ...
Hello There: I am running a data flow within a ForEach loop wherein I am computing a value called QuotaGap. When it is 0 I do not want any further execution of the loop. I am using a Conditional Transform within this dataflow that writes a record to a table only when the QuotaGap is NOT 0. However, I am unable to terminate the execution of the loop as I am still within the dataflow.
Now, the computation of the gap requires a value from another variable called NetPurchases. I tried using an ExecuteSQL task in the control flow but could not figure out how to pass the value of the variable NetPurchases into the select statement to compute the gap. For example, the select statement would read:
select (QuotaUpperLimit - ?) As QuotaGap from <<tablename>>
I tried setting the parameter as an input as well as an output and it did not work.
Then I tried passing the entire SQL as a string within a variable. This does not work either because in order to compute the math QuotaUpperLimit - NetPurchases, both variables need to be integers but then you cannot concatenate integres together, which is what we need to do to create the SQL.
The other reason I am going through these hoops I guess is that I have not figured out a way to set the value of a variable within a data flow. I compute the value for QuotaGap within the dataflow in a ForEach loop but I have no way to pass this result to a variable called QuotaGap without using an ExecuteSQL task or another ForEach Loop.
I have spent hours on this simple issue and so have given up and looking to the good friends in this forum for help.
If what I have stated is not clear please let me know and I will try to clarify things a bit.
Is it possible to set a query result (scalar) to scalar variable. I would like to set a qery result (SELECT COUNT(*) FROM MyTable) to a scalar variable:
DECLARE @temp int
SET @temp = query result...
Is it possible? I couldn't find the way to do that...
I'm using VWD on SQL2005EXPRESS And i keep getting a connection string errorCan someone show me how to put a connection string in the web.config, or which connection string to use to connect to my host database which they're running SQL2000..Thanks Newbie
I need to do something like this in SSIS:From one SQL table I need to get some id values, I am using a simple sql query:Select ID from Identifier where value is not null.I've got this result:As a final result I need to generate and set a variable in SSIS with the final value:
@var = '198','120','ACP','120','PQU'
Which I need to use later in a odbc expression.How can I do this in SSIS?
I'm trying to set the default value of a column (SysInvNum) in a table (caseform) of mine by concatenating 3 other fields in the same table. These other fields are all Integer datatypes. they are "CaseYear" e.g. (2005), "InvNum" e.g. (0001) and "PostId" e.g. (5).
So basically the SysInvNum column for this row should read '200500015'
When I run a basic query using the CAST or CONVERT functions like this:
SELECT convert (varchar,caseyear) + convert(varchar,InvNum) + convert(varchar,postid) from caseform
OR
SELECT cast(caseyear as varchar(4)) + cast(InvNum as varchar(4)) + cast(postid as varchar(1)) from caseform
I get the results I want. But since I want this value to be the default value of the column, I tried inserting this: convert (varchar,caseyear) + convert(varchar,InvNum) + convert(varchar,postid) into the default value parameter of the column in the caseform table. The result is a string that is the query itself.
I then tried creating a UDF called getsysinvnum() where I declare and set 2 variables whilst returning one of the variables as a varchar. An example of what it looks like is this:
CREATE FUNCTION GetSysInvNum() RETURNS varchar AS BEGIN DECLARE @maxcaseid Int DECLARE @sysinvnum varchar
SELECT @maxcaseid = max (caseid) from caseform SELECT @sysinvnum = cast(caseyear as varchar(4)) + cast(invnum as varchar(4)) + cast(postid as varchar(1)) from caseform where caseid = @maxcaseid RETURN @sysinvnum END
The result I get when I plug this into the default value of the column as : ([dbo].[getsysinvnum]()) is "2".
Yes it returns the number "2" could someone please tell me what I am doing wrong, or suggest a better way for me to do this?
I am trying to set the connection string in a connection manager at runtime. Here is what I have done:
1. Created a gv_DataSource, gv_Username and gv_Password
2. Created a ForEach Loop that reads DataSource, Username and password values from a variable (it is an For Each ADO loop Enumerator). The ADO recordset is read into by an Execute SQL task before the loop.
3. Mapped values from the recordset to variable in the ForEach loop's "Variable Mappings" page.
4. Used the variables in my Sybase OLEDB Connection Manager's "Expression" property, setting the "ConnectionString" property to:
5. I set the values in my database table for the connection-I set 2 connections for which I have Sybase OLEDB datasources setup.
When I run the package, I just get the first server's data twice, it doesn't set the second server's data during the second loop. I made sure the first one was working (i.e. the ConnectionString's property was being set by the data from the current variables) by setting the variables incorrectly in the variable properties page, and then running the package. So the first row of connection information is working, but the second loop around it doesn't seem to be working. I used a msgbox in a script task to show that the variables are mapping correctly in the loop, so it seems the second time around the connection information isn't taking from the variables.
I need to make my site aware of which server_name it is loading from so it uses a different connection string. (have dev + prod servers for web/sql)Currently my connection string is in web.config as follows: <connectionStrings> <!-- Development and Staging connection string --> <add name="myconnection" connectionString="server=myserver; user id=mysuer; password=mypassword; database=mydatabase" /> </connectionStrings> I need to make sure the 'name' is the same for both connection strings since that is how the rest of my site looks for it. However, I'm not sure how to get both in here with some sort of 'if/then' statement to determine which one to use.I've heard it could be done in global.asax with something similar to the code below, but I dont know how to assign a 'name' to a connection string for that type of setup. Sub Session_OnStart ServerName = UCase(Request.ServerVariables("SERVER_NAME")) IF ServerName = "prod.server.com" THEN ...Set Prd string... ELSE ...Set Dev string... END IF End Sub
I have a folder of excel files with different file names and sheet names inside the file. So File A could have Sheet1A and file B could have Sheet2B. The assumption is that the sheets would have similar data in them for all files even though sheet names are different. I was able to dynamically create the excel connection string using a for loop and choosing the Data Access mode of the excel source to be Table name or View name variable. I have run into a "[DTS.Pipeline] Error: "component "Excel Source" (1)" failed validation and returned validation status "VS_NEEDSNEWMETADATA".
Was wondering if anybody was able to play in such a scenario and resolve the issue.
By the way a lot of the posts in this blog helped me get this far so thanks for all the posts.
I am facing a strange problem in executing stored procedure. Basically my sproc will take a values from Java application and create a Insert statement. see stored procedure below.Just to give some more background- I am re writing the procedure which was written in oracle already.
Problem I am facing now is with the statement below . When I execute the procedure for first time it works fine however when I execute for second time onwards it is setting to empty. Not sure what is the problem with my declaration and setting up with values. For reference I have pasted my complete stored procedure code below.
Does anyone know what is the maximum size for a string variable that can be used by Execute statement in SQL 7 and SQL 6.5? If I really need to execute a long statement around 9000 characters long, how can I do it?
