Hi I'm new to SQL and I'm trying to build a store procedure. What I'm trying to find out is how to assign a variable a value from a table.
So, I declare a variable:
DECLARE @variable int
Then I want to assign a single int value to that variable that is already in a table. For instance the id value from a single row in a table.
I've tried SELECT INTO and SET, but nothing has worked so far and I'm lost after searching for a few hours.
'check to see that student num is in the db Dim connect as SqlConnection Dim strSelect as String Dim cmdSelect as SqlCommand Dim strDbResult as SqlDataReader
connect = New SqlConnection(connStr) strSelect = "SELECT stu_num, stu_fname, stu_lname FROM " + stuTable + " WHERE stu_num=@stuNum" cmdSelect = New SqlCommand(strSelect,connect) cmdSelect.Parameters.Add("@stuNum", txtStdNum.text)
Dim stuFName as String Dim stuLName as String Dim stuEmail as String Dim strRandom as String Dim strPassword as String Dim i as Integer Dim charIndex as String Dim stuMailMessage as MailMessage Dim strHTMLBody as String
In my DB I have a table with the columns stu_num, stu_fname and stu_lname. Each of these columns contains rows with data. However, the proceeding code gives me this error: Invalid attempt to read when no data is present (line 58 --> stuFName = strDbResult("stu_fname") ).
What am I doing wrong here? How do I assign the stu_fname in the DB to the page level variable stuFName?
As a little aside how do I say "If no record was found matching stuNum Then" ... ??
I have a typical scenario here where I am trying to assign a variable a value using another variable, for that I am using two execute SQL task , the fisrt one assigns the first variable a value and then the second one uses the first variable to evaluate and then assigns a value to another variable. The first execute sql task works fine , however the second one fails with the following error
"failed with the following error: "An error occurred while extracting the result into a variable of type (DBTYPE_I4)". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly. "
Here is the query I am using to assign the value in my second execute sql task
select (CASE
WHEN Sum(col1) <> 0 AND ? = 'M' THEN 'M'
WHEN Sum(col2) <> 0 AND ? >= 'T' THEN 'T'
WHEN Sum(col3) <> 0 AND ? >= 'R' THEN 'R'
ELSE 'S'
END) as Current
FROM dbo.TABLE1
I am passing the variable by mapping the parameters and then assigning the value using a single row result set. Can someone please tell me where am I going wrong?
I would like to assign the value of a variable to a column name of a table. For eg:
declare @sam varchar(100) set @sam = 'Insert' create table #temp(Sample varchar(100) not null) insert into #temp(Sample) Values(@sam) drop table #temp
I would like to generate a table whose column name should be generated dynamically. The value of @sam that is "Insert "should be set to the column name. Is there a way to assign like this. Can anyone please help me in achieving this.
1 20031012121212 200 (recordtype, CreationDateTime(YYYYMMDDHHMISS), Rec_Count) -- Header records 2 ABCD, XYZ, 9999, 999999999, 1234 ---- Detailed Record 2 ABCD, XYZ, 9999, 999999999, 1234 ---- Detailed Record
For the above given sample data I am having two outputs at Condition Split (based on the recordtype). I want to store the 1st record datetime value into a variable and then I want to use that variable value into 2nd and 3rd row.
Basically, detailed records would be stored into the database not the header record. Is there any way I can use the variable while doing processing for 2nd and 3rd records.
Hello all, for a project I am trying to implement PayPal processing for orders public void CheckOut(Object s, EventArgs e) { String cartBusiness = "0413086@chester.ac.uk"; String cartProduct; int cartQuantity = 1; Decimal cartCost; int itemNumber = 1; SqlConnection objConn3; SqlCommand objCmd3; SqlDataReader objRdr3; objConn3 = new SqlConnection(System.Web.Configuration.WebConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString); objCmd3 = new SqlCommand("SELECT * FROM catalogue WHERE ID=" + Request.QueryString["id"], objConn3); objConn3.Open(); objRdr3 = objCmd3.ExecuteReader(); cartProduct = "Cheese"; cartCost = 1; objRdr3.Close(); objConn3.Close(); cartBusiness = Server.UrlEncode(cartBusiness); String strPayPal = "https://www.paypal.com/cgi-bin/webscr?cmd=_cart&upload=1&business=" + cartBusiness; strPayPal += "&item_name_" + itemNumber + "=" + cartProduct; strPayPal += "&item_number_" + itemNumber + "=" + cartQuantity; strPayPal += "&amount_" + itemNumber + "=" + Decimal.Round(cartCost); Response.Redirect(strPayPal);
Here is my current code. I have manually selected cartProduct = "Cheese" and cartCost = 1, however I would like these variables to be site by data from the query. So I want cartProduct = Title and cartCost = Price from the SQL query. How do I do this?
Hello all, I'm creating a stored procedure in SQL Server 2000. I'm trying to count how many rows match a certain WHERE clause, and assigning this integer to a variable:
---------------- DECLARE @RowCount int,
SELECT COUNT(*) FROM Customers WHERE FirstName='Joe' ----------------
How can I assign the count that returns from the SELECT statement to the @RowCount?
I need some help regarding a conversion in a Script Task.
I am reading my variable values from a database with a sql task, the table has two columns, variable and variableValue. Looping through the recordset and setting the different variables works well, with two links: http://blogs.conchango.com/jamiethomson/archive/2005/02/09/SSIS_3A00_-Writing-to-a-variable-from-a-script-task.aspx http://sqlblog.com/blogs/andy_leonard/archive/2007/10/14/ssis-design-pattern-read-a-dataset-from-variable-in-a-script-task.aspx
setting the variable value only works well if the package variable is defined as string, because the db field is a varchar, trying to assign an integer for example brings up an error.
Therefor I tried something like CType: Dts.Variables("MyVar").Value = CType(MyRecordsetField,String), where the target datatype should be depending on the variable datatype instead of being assigned as a constant.
I have a smalldatetime field in a table that holds dates as 3/1/2008. If you run a select query on the field it will bring back the date as a datetime vairable. I reran the query using the following: select convert(varchar,cast((max(ENTRY_DTE))as datetime),101) This query brings me back the date as 03/01/2008.
When I utilize the same query and set the value to a declared variable, defined as datetime, it brings me back the date as : Mar 01 2008 12:00AM
I have tried several different ways to convert the date however as soon as appoint it to a declared variable I receive the same result!!
I've asked this question before and I've read the answers before and I still cannot get it to work. My task is simple, I want to use the execute sql task container to grab a value from a database and put it in a variable. I've done all the preliminary stuff such as running profiler to make sure that the package is getting the call to the database, setting up the ResultSet to be "single row" in the general tab, mapped the Result Set correctly, but nothing works. I get the same error every time.
This is my sql command:
select output_location as output_location from script_master
Result Set is set up like this:
Result Name: output_location ; Variable Name: User::output_location
Here is the error I get:
Error: 0xC002F309 at Execute SQL Task, Execute SQL Task: An error occurred while assigning a value to variable "output_location": "The type of the value being assigned to variable "User::output_location" differs from the current variable type. Variables may not change type during execution. Variable types are strict, except for variables of type Object.
".
I don't know what I'm doing wrong, I've followed all the instructions exactly on how to populate a variable in this container. My variable is set up as a string, if I change it to object I can get it to work. I think this is because the object is allowing nulls. I really believe that the variable is not populating and that is why I'm getting errors.
Please help. If you could provide step by step example's that would really make my day.
How to assign multiple values to emp1 variable separated by comma Ex: If ajay karthik vijay are employee names in emp table then emp1= ajay,karthik, vijay set emp1= (select employeename from emp) returns error error: subquery returns morethan one value
Okay, can I assign line x of a flat file to a variable, parse that line, do my data transformations, and then move on to line x+1?
Any thoughts?
In other words, I'm looking at using a for loop to cycle through a flat file. I have the for loop set up, and the counter's iterating correctly. How do I point at a particular line in a flat file?
Hi, I'm try to get the query second column value when it is assinged to a varchar variable. Ex:In SP below is statement I wrote SET @Values = (SELECT COL1,COL2 FROM TABLE) Question 1: How to access the COL2 value from @Value2? Question 2: How to access the other row values if above returns more than a row? Please send me the solution as soon as possible. Thanks-Vikash/Bala
In my SSIS package I am looping multiple flat file to load data into target table. I have used one variable to get that filename. I have error log table which used to log the invalid record which come from various files.
All are working fine , except I want to log the filename also in my error log table. How can we use the package variable to assign the variable value in script component.so that I can map the output column to target table. I have created Filename column in script component in output column tab.
The following works in query if I specify one student (PlanDetailUID) when running query. If I try to specify multiple students (PlanDetailUID) when running query, I get variable cannot take multiple entries. I assume I would need to replace (variables) in PART 2 with (case statements / using select everywhere) to get around the issue or is there a better way ?
I have a Data Flow Script Component(Destination Type) and in the properties I have a read/write variable called User::giRowCount
User::giRowCount is populated by a Row Count Component previously in the Data Flow.
After reading http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=97494&SiteID=1 it is very clear that you can actually only use variables in the PostExecute of a Data Flow Script Component or you will get an error "Microsoft.SqlServer.Dts.Pipeline.ReadWriteVariablesNotAvailableException: The collection of variables locked for read and write access is not available outside of PostExecute."
What I need to do is actually create a file in the PreExecute and write the number of records = User::giRowCount as second line as part of the header, I also need to parse a read/write variable such as gsFilename to save me hardcoding the path
-they must go in the PreExecute sub --workarounds please-here is the complete script component that creates a file with header, data and trailer --Is there any workaround
Public Class ScriptMain Inherits UserComponent 'Dim fs As FileStream Dim fileName As String = "F:FilePickUpMyfilename.csv" 'Dim fileName = (Me.Variables.gsFilename.ToString)
Dim myFile As FileInfo = New FileInfo(fileName) Dim sw As StreamWriter = myFile.CreateText Dim sbRecord As StringBuilder = New StringBuilder

sbRecord.Append("RECORD_START").Append(vbNewLine)
End Sub

I have variables and values stored in a table in this format
process_id | t_variable | t_value ----------------------------------------------------- 1 | Remote_Log_Server | AUSCPSQL01 ... many such rows
how to assign values to variables in SSIS?
basically i'm looking for SQL equivalent of the following query i currently use to assign values to multiple variables (in a single query)
SELECT @varRemoteLogServer=MAX(CASE WHEN [t_variable] = 'Remote_Log_Server' THEN [t_value] END) ,@varVariable2=MAX(CASE WHEN [t_variable] = 'variable2_name' THEN [t_value] END) FROM Ref_Table WHERE process_id=1
insert into #t(branchnumber) values (005) insert into #t(branchnumber) values (090) insert into #t(branchnumber) values (115) insert into #t(branchnumber) values (210) insert into #t(branchnumber) values (216)
[code]....
I have a parameter which should take multiple values into it and pass that to the code that i use. For, this i created a parameter and temporarily for testing i am passing some values into it.Using a dynamic SQL i am converting multiple values into multiple records as rows into another variable (called @QUERY). My question is, how to insert the values from variable into a table (table variable or temp table or CTE).OR Is there any way to parse the multiple values into a table. like if we pass multiple values into a parameter. those should go into a table as rows.
Simple example: declare @tTable(col1 int) insert into @tTable(col1) values (1) select * from @tTable
Works perfectly in SQL Server Management Studio and the database connection is OK to as I may generate PP table using complex (or simple) queries without difficulty.
But when trying to get this same result in a PP table I get an error, idem when replacing table variable by a temporary table.
Message: OLE DB or ODBC error. .... The current operation was cancelled because another operation the the transaction failed.
I am trying to use a stored procedure to update a column in a sql table using the value from a variable table I getting errors because my syntax is not correct. I think table aliases are not allowed in UPDATE statements.
This is my statement:
UPDATE [dbo].[sessions_teams] stc SET stc.[Talks] = fmt.found_talks_type FROM @Find_Missing_Talks fmt WHERE stc.sessionid IN (SELECT sessionid FROM @Find_Missing_Talks) AND stc.coupleid IN (SELECT coupleid FROM @Find_Missing_Talks)
Can someone tell me if it is possible to add an index to a Table variable that is declare as part of a table valued function ? I've tried the following but I can't get it to work.
ALTER FUNCTION dbo.fnSearch_GetJobsByOccurrence ( @param1 int, @param2 int ) RETURNS @Result TABLE (resultcol1 int, resultcol2 int) AS BEGIN
