I know passing table/column name as parameter to a stored procedure is
not good practice, but sometimes I need to do that occasionally. I
know there's a way can do that but forget how. Can someone refresh my
memory?
Thanks.

Is there a way to pass the column name as a query parameter?? If I use '@Question', like below, I get an error. If I change it to the actual name of the column 'Question1', it works fine. However, I need it to be dynamic so I can pass the column name [Question1, Question2, Question3, etc...] in and not have to define this for each question.
Doesn't Work!!
Code:
SELECT
1.0 * SUM(CASE WHEN @ColumnName > 1 THEN 1 ELSE 0 END) / COUNT(*) AS 'Good', 1.0 * SUM(CASE WHEN @ColumnName = 0 THEN 1 ELSE 0 END)/ COUNT(*) AS 'OK', 1.0 * SUM(CASE WHEN @ColumnName < 0 THEN 1 ELSE 0 END) / COUNT(*) AS 'Poor'
FROM tableA AS A INNER JOIN tableB AS B ON A.SessionID = B.SessionID
WHERE (A.SurveyID = @SurveyID) AND (A.SubmitDate BETWEEN @BeginDate AND @EndDate)
Works, but I need to pass in the column name dynamically.
Code:
SELECT
1.0 * SUM(CASE WHEN Question1 > 1 THEN 1 ELSE 0 END) / COUNT(*) AS 'Good', 1.0 * SUM(CASE WHEN Question1 = 0 THEN 1 ELSE 0 END)/ COUNT(*) AS 'OK', 1.0 * SUM(CASE WHEN Question1 < 0 THEN 1 ELSE 0 END) / COUNT(*) AS 'Poor'
FROM tableA AS A INNER JOIN tableB AS B ON A.SessionID = B.SessionID
WHERE (A.SurveyID = @SurveyID) AND (A.SubmitDate BETWEEN @BeginDate AND @EndDate)

I'm writing reports in Rep. Services that reads data from Dynamics NAV (Navision). In NAV data are stored by company and this is implemented by using the company name as prefix to the table name. This means that in a NAV database with three companies (lets call these companies A, B and C) we will have three tables with customers. The table names will be A$Customer, B$Customer and C$Customer.
Now to my problem:
I wan't to write one report where I can choose company. I do not want to use a stored procedure. I want to use a function so I can use the function in select statements and join several functions to build up a report that needs data from several tables.
Is there some way to pass the table name or a part of the table name to a function that returns the content of the actual table? I know I can pass parameters that I can use in the where clause, but is it possible to do it with the table name. Or is there any other way to solve this.
I am trying to develop a stored procedure for an existing application thathas data stored in numerous tables, each with the same set of columns. Themain columns are Time and Value. There are literally hundreds of thesetables that are storing values at one minute intervals. I need to calculatethe value at the end of the current hour for any table. I am a little newto SQL Server, but I have some experience with other RDBMS.I get an error from SQL Server, complaining about needing to declare@TableName in the body of the procedure. Is there a better way to referencea table?SteveHere is the SQL for creating the procedure:IF EXISTS(SELECTROUTINE_NAMEFROMINFORMATION_SCHEMA.ROUTINESWHEREROUTINE_TYPE='PROCEDURE'ANDROUTINE_NAME='udp_End_of_Hour_Estimate')DROP PROCEDURE udp_End_of_Hour_EstimateGOCREATE PROCEDURE udp_End_of_Hour_Estimate@TableName VarCharASDECLARE @CurrentTime DateTimeSET @CurrentTime = GetDate()SELECT(SELECTSum(Value)* DatePart(mi,@CurrentTime)/60 AS EmissonsFROM@TableNameWHERETime BETWEENDateAdd(mi,-DatePart(mi,@CurrentTime),@CurrentTime)AND@CurrentTime)+(SELECTAvg(Value)* (60-DatePart(mi,@CurrentTime))/60 AS EmissionsFROM@TableNameWHERETime BETWEENDateAdd(mi,-10,@CurrentTime)AND@CurrentTime)
can i pass the name of the table and the "order by" column name to stored procedure? i tried the simple way (@tablename varchar and then "select * from @tablename) but i get error massesges. the same for order by... what is the right syntex for this task?
Dear All - iam facing a problem for passing a parameter to update paradox table statment in the OLE DB Command
Briefly an OLE DB Command exist between OLE DB Source and OLE DB destination , all i want it to send the data that flow from the OLE DB Source to the update paradox table statment in OLE DB Command ,
i use the parameter annotation which is "?" to refer to the parameter in the update where clause and it sucess when i use the OLE DB Command to connect to SQL Server DB but when i use it with the Paradox Table an error appear saying that there is more than one data source column with the name "?" The data source column names must be unique.
i dont know what that means is it means that "?" it consider "?" as a column or what or is there another way to send parameter to Update statment for the paradox table differ from the SQL Server Update statment which is the "? "
i hope someone help me as soon as possible because i need it in work sOOon Thanks, Maylo
We are working on C++ in eVC++ 3.0 environment (CE 3.0) with SQL CE 2.0.
We are trying with IRowsetIndex:: Seek method to access the data from the database. We are facing problem when we try to access data from the table having composite index other than the first column.
For example: The table ITEM contains the following columns: 1. ItemCode 2. PcNo 3. SubPcNo 4. BrandNo 5. DescText 6. ProductionKind 7. ProductionState 8. ClearingState 9. ST 10. TS
I€™ve two indexes for this table where the two indexes are 1. ItemKey1 on ITEM (ItemCode). 2. ItemKey2 on ITEM (PcNo, SubPcNo, BrandNo).
If I mention ItemKey1 as the index then the Seek method works perfectly.
But if I mention ItemKey2 as the index, then I€™m getting the error as €śDB_E_BADBINDINFO€?.
When we visted the MSDN for this problem we noted that: 1. When you use the Seek method on multiple fields, the Seek fields must be in the same order as the fields in the underlying table. If they are not, the Seek method fails. 2. When passing key values to an index rowset, the consumer performs these actions only for the number of key columns specified in the cKeyValues argument in IRowsetIndex:: Seek.
So we had the composite index such that columns of a composite index are physically aligned next to each other as in the table. When the first column of the index is the first column of the table as in index ItemKey1 we found that the seek method works perfectly. If we pass the index ItemKey2, we are again getting the error €śDB_E_BADBINDINFO€?.
What else have we missed out while passing the keys in IRowsetIndex:: Seek?
I'm running 2014 enterprise and getting an error on this form of a query...it says the multi part identifier "mns.col3" could not be bound. I'm aware that a cross apply would be more appropriate but i'm just prototyping and probably going to move to a set based approach anyway.The udf returns a table.
select mns.col1, mns.col2 from table1 mns left join dbo.udf_udf1(@firstofmonth,@lastofmonth, mns.col3) x on 1=1
I have two report , first is main report which is matrix and have one parameter User_ids which is multi value selection and my second report is basic chart of user_wise performance.
Now, my main report (matrix ) works fine for Multiple selection of users and i have putted one textbox on main report chart which has action properties set for chart report, when user click on chart button it must goes to chart with user selected in main report. Now , i have used expression for parameter to send it like ..
=join(parameter!user_id!value,",") which pass selected value to chartÂ
And when I am selecting single user it passing that value to chart parameter list but , when it is more than one user it errors with conversion failed when converting the nvarchar value '121,128' to data type int. But my chart also works when passing 121,128 in user parameter in preview of report .
Using SQL Server 2008R2 and Report Builder 3.0..I have an action set in a text box of a table. My intent is to pass the value of that text box (which is variable) to a sub-report in a popup window. Here's my code: URL....The parameter of the report I'm trying to open is @SONum.I'm guessing my error is involved in the formatting of how the value of the parameter is being passed. I've also seen examples where the report server and report values were parameterized, but I don't know where to define
Parameters!ServerAddress.Value anywhere.Do I need to have something set up a certain way within the report I'm opening? Here's the report Parameter settings on the report I'm trying to open.
In VB.NET this doesn't work either: dim s as string = "'cn01','cn02','cn03','cn04'" cmd.parameters.add(new sqlparameter("@Cno",nvarchar,1000)) cmd.parameters("@Cno").value = s
I don't want to parse the string inside the proc and then Exec the parsed string.
I have this situation,I need to store results of a Select Count(*) from TableA to a parameter and only if the value of the count(*) is greater than 50,000,a notification mail would be sent out to the table owner.Currently this is what I have done: 1) Use SQL task to include "Select Count(*) from TableA" 2) In parameter mapping tab of SQL Task, define the following Parameter name : Table::Count Direction: Input Data Type: Numeric Parameter Name : @Count 3) I have connected the SQL Task to a Send Mail Task [ Only If @count>50 000, then a mail should be sent out] 4) The constraints has been set as Evaluation Operation : Expression and Constraints Value: Success Expression : @Count >"50000"
In SSIS tab > Variable I have set the following Variable Name : Count DataType : Int32
Can someone advise me where I am going wrong, as when I execute the SQL Task turns greens and ends.Even when the count of tableA is greater than 50 000, no mails I sent out[send mail task does not get executed]
I have a stored procedure named "processInventory" like the following.Depending on the passed in parameters, I would like to add a WHEREclause for "select" action. For example, if any varchar type ofparameter is passed in, the where clause would use "LIKE" operator. Forexample, "Select * from Main where [s/n] like @Serial. All other typeswill use "=" operator. For example, "Select * from Main where MAKE =@Make and Type = @type".How could this be achieved?

I don't understand how to pass a parameter to a dts package from another. In SQL 2000 you can map a variable with a variable of the package you will call.
As of now I'm working on a certian report which needs to pass a certain parameter to another dataset... I'm refering to the dataset of the same report. Can anyone tell me how this is done? I really need to know it to finish my report...
My data table contains a column (a foreign key) with numbers from 0 and up. (it could be null or a number. I used ISNULL to convert it.) I want to be able to select in three ways. 1) equals zero (or is null)2) greater than zero (or is not null)3) equal to a specific number.How do I do this?My application setup is Presentation Layer, BLL, DAL and Sql Server.I don't want to create another Query because this is only part of a larger query with other parameters.If I could just do something like @IDOperator @IDValue in the Filter of the Sql it would be great.
Hello, Can someone kindly point out what is wrong with the following code file. I'm trying to: - fill a dropdown from a db on page load (this works!) - when user selects from the list and hits a button, pass the dropdown value to a second query - use the second query to make another call to the db and fill a data grid
In the code below, if I swap an actual value (eg '1005') into the command and comment out the .Parameter.Add statements, the dategrid is filled sucessfully. Otherwise, when the button is pressed, nothing is displayed.
Thanks
