Using Variable In Where Clause
I am trying to use a local variable and case statment in a where clause but I keep getting an error. I'm passing an input parameter into a stored procedure and based on the input parameter I want the WHERE clause to reflect.
spOpenClosedList @openclose varchar(5)
DECLARE @result varchar(12)
if @openclose = 'open'
Begin
set @result = 'is null'
end
else
set @result = 'is not null'
SELECT * FROM WorkOrderTbl
WHERE WorkOrderTbl.CompletedDate @result
AND username = "Thomas"

Order By Clause Using A Variable
I am trying to pass as an input parameter a user selected order by clause, and instead of repeating the SQL statement with a new Order By based on the parameter, I want to set the Order by using this parameter. I can't get it to work. Here is the statement: Create Procedure sp_InfoDump ( @StartDate varchar(12), @EndDate varchar(12), @OrderBy varchar(50) ) As /* Local variables */ DECLARE @MinDate datetime, @MaxDate datetime IF @StartDate = 'ALL DATES' BEGIN SELECT @MinDate = Min(AccessTime) FROM tblAudit END ELSE BEGIN SELECT @MinDate = @StartDate END IF @EndDate = 'ALL DATES' BEGIN SELECT @MaxDate = Max(AccessTime) FROM tblAudit END ELSE BEGIN SELECT @MaxDate = @StartDate END BEGIN SELECT tblReports.ReportName, tblReports.ReportCode, tblAudit.BadAttempts, tblAudit.LogonUser, tblAudit.AccessTime, tblAudit.RemoteHost, tblAudit.RemoteIdent, tblAudit.ExitTime, tblAudit.BrowserType, tblAudit.Access_ID, TotalTime=DateDiff(Minute,tblAudit.AccessTime,tblA udit.ExitTime) FROM tblReports INNER JOIN tblReportsAccess ON tblReports.Report_ID = tblReportsAccess.Report_ID INNER JOIN tblAudit ON tblReportsAccess.Audit_ID = tblAudit.Audit_ID WHERE tblAudit.AccessTime >= @MinDate AND tblAudit.AccessTime <= @MaxDate ORDER BY (SELECT 'ColumnName'=ColumnName FROM tblOrderBy WHERE ColumnName = @OrderBy) END RETURN

Using A @Variable As An IN Clause Expression
Is there a good way to use a @variable in a Stored procedure to represent the expressions for an IN clause I.e.

The above code presented here does not work, because the VarChar cannot be translated into int.

Use A Variable Along With The FROM Clause In SELECT Statement
I have a table 'table_list' which contains two columns, table_name and a record_count. This table stores a list of tables and their corresponding record counts. What I am trying to do is, to be able to write a select statement, that can read each table name in the 'table_name' column, execute a select count(*) for the same, and update its record_count with the result of select count(*). This is the code in my procedure.. DECLARE @tab_list CURSOR set @tab_list = CURSOR FOR select * from table_list OPEN @tab_list DECLARE @tab_name varchar(256) DECLARE @rec_cnt int FETCH NEXT FROM @tab_list INTO @tab_name, @rec_cnt select count(*) from @tab_name This select is looping around along with FETCH till all the table names are exhausted and their counts are updated from the cursor back into the table. Problem is that, I am not able to use select count(*) from @tab_name, and its not accepting a variable there. Please help me to construct the select statement that is similiar to x=<table name> select * from x where x is a variable and the table name gets substituted. what is the syntax for it ?

Using A Stored Procedure Variable To Define A Where Clause
Hi all, I'm trying to build a Where clause in a stored procedure based on the information that is passed into the stored procedure. Because I don't know how many items will be passed into the stored procedure, I'm having to split the string on a specific character and build the Where clause based on how many strings are found. However, when I try to execute the Where clause it throws an error. Code Snippet ALTER PROCEDURE getUsersAddress -- Add the parameters for the stored procedure here @LName varchar(1000) @City varchar(1000), @State varchar(1000), @License varchar(1000) AS declare @Count as int declare @x as int declare @wLName as varchar(2000) declare @wCityas varchar(2000) declare @wStateas varchar(2000) declare @wLicense as varchar(2000) BEGIN -- SET NOCOUNT ON added to prevent extra result sets from -- interfering with SELECT statements. SET NOCOUNT ON; if right(rtrim(@LName),1) <> ';' begin set @LName = @LName + ';' end set @Count = PATINDEX('%;%',@LName) set @wLName = '(tblUsers.LName = ''' while @Count <> 0 begin set @wLName = @wLName + left(@LName, @Count - 1) set @LName = stuff(@LName, 1, @Count, '') set @Count = PATINDEX('%;%',@LName); if @Count <> 0 begin set @wLName = @wLName + ''') OR (tblUsers.LName = ''' end else begin set @wLName = @wLName + ''')' end end print cast(@wLName as varchar(5000)) -- Insert statements for procedure here SELECT tblUsers.FullName, tblUsers.Addy1, tblUsers.Addy2, tblUsers.City, tblState.StateAbbr, tblUsers.Zip, tblUsers.Zip4 FROM tblUsers INNER JOIN tblState ON tblUsers.FK_StateID = tblState.StateID INNER JOIN tblUserDetails ON tblUsers.UserID = tblUserDetails.FK_UserID WHERE (@wLName) OR (tblUsers.City = @City) OR (tblState.StateAbbr = @State) OR (tblUserDetails.CDLType = @License) END So when I print do an exec getUsersAddress 'Johnson;Smith', 'City;Test City', 'TX;OK', 'Class A;Class B' @wLName comes out as (tblUsers.LName = 'Johnson') OR (tblUsers.LName = 'Smith') However, I can't save the procedure as it gives me an error of: An expression of non-boolean type specified in a context where a condition is expected, near 'OR'. When I copy and paste the @wLName value in place of @wLName in the Where clause it works, so how can I get the @wLName variable to work in that Where clause?

Filtering Results In The Where Clause Vs A Having Clause
I am working with a vendor on upgrading their application from SQL2K to SQL2K5 and am running into the following. When on SQL Server 2000 the following statement ran without issue: UPDATE dbo.Track_ID SET dbo.Track_ID.Processed = 4 --Regular 1 leg call thats been completed WHERE Processed = 0 AND LegNum = 1 AND TrackID IN ( SELECT TrackID FROM dbo.Track_ID GROUP BY TrackID HAVING MAX(LegNum) = 1 AND TrackID + 'x1' IN ( SELECT dbo.Track_ID.TrackID + 'x' + CONVERT(NVARCHAR(2), COUNT(dbo.Track_ID.TrackID)) FROM dbo.Track_ID INNER JOIN dbo.transactions ON dbo.Track_ID.SM_ID = dbo.transactions.sm_session_id GROUP BY dbo.Track_ID.TrackID ) ) Once moved to SQL Server 2005 the statement would not return and showed SOS_SCHEDULER_YIELD to be the waittype when executed. This machine is SP1 and needs to be upgraded to SP2, something that is not going to happen near time. I changed the SQL to the following, SQL Server now runs it in under a second, but now the app is not functioning correctly. Are the above and the following semantically the same? UPDATE dbo.Track_ID SET dbo.Track_ID.Processed = 4 --Regular 1 leg call thats been completed WHERE Processed = 0 AND LegNum = 1 AND TrackID IN ( SELECT TrackID FROM dbo.Track_ID WHERE TrackID + 'x1' IN ( SELECT dbo.Track_ID.TrackID + 'x' + CONVERT(NVARCHAR(2), COUNT(dbo.Track_ID.TrackID)) FROM dbo.Track_ID INNER JOIN dbo.transactions ON dbo.Track_ID.SM_ID = dbo.transactions.sm_session_id GROUP BY dbo.Track_ID.TrackID ) GROUP BY TrackID HAVING MAX(LegNum) = 1 )

Having Clause Without GROUP BY Clause?
Hi, What is HAVING clause equivalent in the following oracle query, without the combination of "GROUP BY" clause ? eg : SELECT SUM(col1) from test HAVING col2 < 5 SELECT SUM(col1) from test WHERE x=y AND HAVING col2 < 5 I want the equivalent query in MSSQLServer for the above Oracle query. Also, does the aggregate function in Select column(here the SUM(col1)) affect in anyway the presence of HAVING clause?. Thanks, Gopi.

SSIS Script Task Alters Package Variable, But Variable Does Not Change.
I'm working on an SSIS package that uses a vb.net script to grab some XML from a webservice (I'd explain why I'm not using a web service task here, but I'd just get angry), and I wish to then assign the XML string to a package variable which then gets sent along to a DataFlow Task that contains an XML Source that points at said variable. when I copy the XML string into the variable value in the script, if do a quickwatch on the variable (as in Dts.Variable("MyXML").value) it looks as though the new value has been copied to the variable, but when I step out of that task and look at the package explorer the variable is its original value. I think the problem is that the dataflow XML source has a lock on the variable and so the script task isn't affecting it. Does anyone have any experience with this kind of problem, or know a workaround?

Passing A SSIS Global Variable To A Declared Variable In A Query In SQL Task
I have a SQL Task that updates running totals on a record inserted using a Data Flow Task. The package runs without error, but the actual row does not calculate the running totals. I suspect that the inserted record is not committed until the package completes and the SQL Task is seeing the previous record as the current. Here is the code in the SQL Task: DECLARE @DV INT; SET @DV = (SELECT MAX(DateValue) FROM tblTG); DECLARE @PV INT; SET @PV = @DV - 1; I've not been successful in passing a SSIS global variable to a declared parameter, but is it possible to do this: DECLARE @DV INT; SET @DV = ?; DECLARE @PV INT; SET @PV = @DV - 1; I have almost 50 references to these parameters in the query so a substitution would be helpful.

SSIS Error Reading XML Loaded Into Variable With XML Source Using XML File From Variable.
Hi I am getting the following error when trying to extract data using XML source " Error: 0xC02090D0 at Data Flow Task - Load XML data to database, XML Source - Load XML data from variable [15893]: The component "XML Source - Load XML data from variable" (15893) was unable to read the XML data." What I have done is read XML data from file and stripped out DTD contents using XSLT transformation in an XML task. The XML file is loaded into a string variable called XMLProduct. Next I have a XML task to validate the variable contents against the XSD, which works. Then I am trying to load the data using XML Source within a Data Flow task, which is when the error occurs. If before I enter the Data Flow and use a script task to read the content of XMLProduct variable and save that to a file then point XML Source task to the file it works ok. I need to iterate through a whole bunch of XML files so reading it into a variable would be the preferred option if it worked of course. Any help would be hugely appreciated. Edit --- I have saved the output from the XSLT transformation XML Task to file and not a variable then read that in using the XML source task and it worked. It would be nice to get the variable method working though as it would save having to create another file. It is a work around at the moment though.

SSIS: Problem Mapping Global Variables To Stored Procedure. Can't Pass One Variable To Sp And Return Another Variable From Sp.
I'm new to SSIS, but have been programming in SQL and ASP.Net for several years. In Visual Studio 2005 Team Edition I've created an SSIS that imports data from a flat file into the database. The original process worked, but did not check the creation date of the import file. I've been asked to add logic that will check that date and verify that it's more recent than a value stored in the database before the import process executes. Here are the task steps. [Execute SQL Task] - Run a stored procedure that checks to see if the import is running. If so, stop execution. Otherwise, proceed to the next step. [Execute SQL Task] - Log an entry to a table indicating that the import has started. [Script Task] - Get the create date for the current flat file via the reference provided in the file connection manager. Assign that date to a global value (FileCreateDate) and pass it to the next step. This works. [Execute SQL Task] - Compare this file date with the last file create date in the database. This is where the process breaks. This step depends on 2 variables defined at a global level. The first is FileCreateDate, which gets set in step 3. The second is a global variable named IsNewFile. That variable needs to be set in this step based on what the stored procedure this step calls finds out on the database. Precedence constraints direct behavior to the next proper node according to the TRUE/FALSE setting of IsNewFile. If IsNewFile is FALSE, direct the process to a step that enters a log entry to a table and conclude execution of the SSIS. If IsNewFile is TRUE, proceed with the import. There are 5 other subsequent steps that follow this decision, but since those work they are not relevant to this post. Here is the stored procedure that Step 4 is calling. You can see that I experimented with using and not using the OUTPUT option. I really don't care if it returns the value as an OUTPUT or as a field in a recordset. All I care about is getting that value back from the stored procedure so this node in the decision tree can point the flow in the correct direction. CREATE PROCEDURE [dbo].[p_CheckImportFileCreateDate] /* The SSIS package passes the FileCreateDate parameter to this procedure, which then compares that parameter with the date saved in tbl_ImportFileCreateDate. If the date is newer (or if there is no date), it updates the field in that table and returns a TRUE IsNewFile bit value in a recordset. Otherwise it returns a FALSE value in the IsNewFile column. Example: exec p_CheckImportFileCreateDate 'GL Account Import', '2/27/2008 9:24 AM', 0 */ @ProcessName varchar(50) , @FileCreateDate datetime , @IsNewFile bit OUTPUT AS SET NOCOUNT ON --DECLARE @IsNewFile bit DECLARE @CreateDateInTable datetime SELECT @CreateDateInTable = FileCreateDate FROM tbl_ImportFileCreateDate WHERE ProcessName = @ProcessName IF EXISTS (SELECT ProcessName FROM tbl_ImportFileCreateDate WHERE ProcessName = @ProcessName) BEGIN -- The process exists in tbl_ImportFileCreateDate. Compare the create dates. IF (@FileCreateDate > @CreateDateInTable) BEGIN -- This is a newer file date. Update the table and set @IsNewFile to TRUE. UPDATE tbl_ImportFileCreateDate SET FileCreateDate = @FileCreateDate WHERE ProcessName = @ProcessName SET @IsNewFile = 1 END ELSE BEGIN -- The file date is the same or older. SET @IsNewFile = 0 END END ELSE BEGIN -- This is a new process for tbl_ImportFileCreateDate. Add a record to that table and set @IsNewFile to TRUE. INSERT INTO tbl_ImportFileCreateDate (ProcessName, FileCreateDate) VALUES (@ProcessName, @FileCreateDate) SET @IsNewFile = 1 END SELECT @IsNewFile The relevant Global Variables in the package are defined as follows: Name : Scope : Date Type : Value FileCreateDate : (Package Name) : DateType : 1/1/2000 IsNewFile : (Package Name) : Boolean : False Setting the properties in the "Execute SQL Task Editor" has been the difficult part of this. Here are the settings. General Name = Compare Last File Create Date Description = Compares the create date of the current file with a value in tbl_ImportFileCreateDate. TimeOut = 0 CodePage = 1252 ResultSet = None ConnectionType = OLE DB Connection = MyServerDataBase SQLSourceType = Direct input IsQueryStoredProcedure = False BypassPrepare = True I tried several SQL statements, suspecting it's a syntax issue.

The IsNewFile global variable is scoped at the package level and has a Boolean data type, and the Output parameter in the stored procedure is defined as a Bit. So what gives? The "Possible Failure Reasons" message is so generic that it's been useless to me. And I've been unable to find any examples online that explain how to do what I'm attempting. This would seem to be a very common task. My suspicion is that one or more of the settings in that Execute SQL Task node is bad. Or that there is some cryptic, undocumented reason that this is failing. Thanks for your help.

Compare The Value Of A Variable With Previous Variable From A Function ,reset The Counter When Val Changes
I am in the middle of taking course 2073B €“ Programming a Microsoft SQL Server 2000 Database. I noticed that in Module9: Implementing User-Defined Functions exercise 2, page 25; step 2 is not returning the correct answer. Select employeeid,name,title,mgremployeeid from dbo.fn_findreports(2) It returns manager id for both 2 and 5 and I think it should just return the results only for manager id 2. The query results for step 1 is correct but not for step 2. Somewhere in the code I think it should compare the inemployeeid with the previous inemployeeid, and then add a counter. If the two inemployeeid are not the same then reset the counter. Then maybe add an if statement or a case statement. Can you help with the logic? Thanks! Here is the code of the function in the book: /* ** fn_FindReports.sql ** ** This multi-statement table-valued user-defined ** function takes an EmplyeeID number as its parameter ** and provides information about all employees who ** report to that person. */ USE ClassNorthwind GO /* ** As a multi-statement table-valued user-defined ** function it starts with the function name, ** input parameter definition and defines the output ** table. */ CREATE FUNCTION fn_FindReports (@InEmployeeID char(5)) RETURNS @reports TABLE (EmployeeID char(5) PRIMARY KEY, Name nvarchar(40) NOT NULL, Title nvarchar(30), MgrEmployeeID int, processed tinyint default 0) -- Returns a result set that lists all the employees who -- report to a given employee directly or indirectly AS BEGIN DECLARE @RowsAdded int -- Initialize @reports with direct reports of the given employee INSERT @reports SELECT EmployeeID, Name = FirstName + ' ' + LastName, Title, ReportsTo, 0 FROM EMPLOYEES WHERE ReportsTo = @InEmployeeID SET @RowsAdded = @@rowcount -- While new employees were added in the previous iteration WHILE @RowsAdded > 0 BEGIN -- Mark all employee records whose direct reports are going to be -- found in this iteration UPDATE @reports SET processed = 1 WHERE processed = 0 -- Insert employees who report to employees marked 1 INSERT @reports SELECT e.EmployeeID, Name = FirstName + ' ' + LastName , e.Title, e.ReportsTo, 0 FROM employees e, @reports r WHERE e.ReportsTo = r.EmployeeID AND r.processed = 1 SET @RowsAdded = @@rowcount -- Mark all employee records whose direct reports have been -- found in this iteration UPDATE @reports SET processed = 2 WHERE processed = 1 END RETURN -- Provides the value of @reports as the result END GO

Variable Indirection: Choosing Variable At Runtime
Hello! I'm using SQL Server 2000. I have a variable which contains the name of another variable scoped in my stored procedure. I need to get the value of that other variable, namely: DECLARE @operation VARCHAR(3) DECLARE @parameterValue VARCHAR(50) SELECT @operation='DIS' CREATE table #myTable(value VARCHAR(20)) INSERT into #myTable values('@operation') SELECT top 1 @parameterValue = value from #myTable -- Now @parameterValue is assigned the string '@operation' -- Here I need some way to retrieve the value of the @operation variable I declared before (in fact -- another process writes into the table I retrieved the value from), in this case 'DIS' DROP TABLE #myTable I've tried several ways, but didn't succeed yet! Please tell me there's a way to solve my problem!!! Thank you very much in advance!

Foreach From Variable Using 2 Dim Array Variable
Is there any way to use a 2 dimensional array of strings as the Variable Enumerator for the "Foreach From Variable Enumerator". I am trying to copy a collection of files from folder A to folder B. In a script, I would populate, let us say, an array of (2,10), for 10 files, with one column representing the source file and other column representing the target column task. Then I would like to set this string array variable as the "Variable Enumerator" for the "Foreach From Variable Enumerator" and use file system tasks in the foreach loop to perform the tasks. The problem is that the "Foreach From Variable Enumerator" does not let me choose an index, but passes only one index 0, so, I will only be able to pass just one column. How do I let the foreach enumerator let me choose an index. The other foreach enumerators, foreach item and ADO give me the option to select index. I would like the same functionality in the foreach variable. Note: I cannot use the "For Each File" enumerator, since the files are to be selected by a script only. Thanks for the help.

SQL Variable And IS Variable In Execute SQL Task
Hi, I have an Execute SQL Task (OLE DB Connnection Manager) with a SQL script in it. In this script I use several SQL variables (@my_variable). I would like to assign an IS variable ([User::My_Variable]) to one of my SQL variables on this script. Example: DECLARE @my_variable int , <several_others> SET @my_variable = ? <do_some_stuff> Of course, I also set up the parameter mapping. However, it seems this is not possible. Assigning a variable using a ? only seems to work in simple T-SQL statements. I have several reasons for wanting to do this: - the script uses several variables, several times. Not all SQL variables are assigned via IS variables. - For reading and mainenance purposes, I prefer to pass the variable only once. Otherwise every time the script changes u need to keep track of all questionmarks and their order. - Passing the variable once also makes it easier to design the script outside IS using Management Studio. - This script only does preparation for the actual ETL, so I prefer to keep it in one task instead of taking it apart to several consecutive Execute SQL Tasks. - I prefer to use the OLE DB connection manager because it's a de facto standard here. Could anyone help me out with the following questions: - Is the above possible? - If so, how? - If not, why not? - If not, what would be the best way around this problem? Thanx in advance, Pipo

Variable Inside A Variable From Sql TAsk
I've got two Sql Tasks on my dtsx. The first one loads a value into "Proyecto" user variable and the second one executes a variable named "SegundoProceso" which contains from the beginning: "select Fecha from LogsCargaExcel where Proyecto = " + @[User::Proyecto] +"" As SqlSourceType propety I have "Variable" and inside ResultSet or Parameter Mapping nodes there is nothing. [Execute SQL Task] Error: Executing the query ""select Fecha from LogsCargaExcel where Proyecto = " + @[User::Proyecto] +""" failed with the following error: "Cannot use empty object or column names. Use a single space if necessary.". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly.

Passing Variable Value Through Environment Variable
Hi All! I have a parent package that contains two children... The second child depends on the succes of the first child. THe first child generates a variable value and stores it in an Environment variable ( Visibility - All ) ...After the first succeeds, the second will start executing and will pick up the variable value from environment variable( through package configuration setting )... Unfortunately, this doesn't work...As the second child picks the stale value of the environment variables...Essentially it assigns variable value not after the first child is finished, but right at the beginning of parent execution... I tried to execute coth children as Out Of Proc as well as In Proc...The same Would anybody have an idea how to resolve this problem? Thanks in advance for any help! Vladimir

Is It Possible To Re-reference A Column Alias From A Select Clause In Another Column Of The Same Select Clause?
Example, suppose you have these 2 tables(NOTE: My example is totally different, but I'm simply trying to setupthe a simpler version, so excuse the bad design; not the point here)CarsSold {CarsSoldID int (primary key)MonthID intDealershipID intNumberCarsSold int}Dealership {DealershipID int, (primary key)SalesTax decimal}so you may have many delearships selling cars the same month, and youwanted a report to sum up totals of all dealerships per month.select cs.MonthID,sum(cs.NumberCarsSold) as 'TotalCarsSoldInMonth',sum(cs.NumberCarsSold) * d.SalesTax as 'TotalRevenue'from CarsSold csjoin Dealership d on d.DealershipID = cs.DealershipIDgroup by cs.MonthIDMy question is, is there a way to achieve something like this:select cs.MonthID,sum(cs.NumberCarsSold) as 'TotalCarsSoldInMonth',TotalCarsSoldInMonth * d.SalesTax as 'TotalRevenue'from CarsSold csjoin Dealership d on d.DealershipID = cs.DealershipIDgroup by cs.MonthIDNotice the only difference is the 3rd column in the select. Myparticular query is performing some crazy math and the only way I knowof how to get it to work is to copy and past the logic which isgetting out way out of hand...Thanks,Dave

Sql Where Clause - Help
Hey guys, I'm a bit weak when it comes to doing ands and or's. I know what i want, but when I put it into statement, i dont get the results that i want. I have 3 fields in my where clause. ID, LW, and LWU. The code is as follows:WHERE (LASTVISIT BETWEEN '1 / 1 / 95 12 : 00 : 00 AM' AND '1 / 1 / 06 12 : 00 : 00 AM') AND (ID NOT LIKE '%6%') AND (ID NOT LIKE '%7%') AND (ID NOT LIKE '%8%') AND (LW <> 1) AND (LWU <> 'test') OR (LASTVISIT BETWEEN '1 / 1 / 95 12 : 00 : 00 AM' AND '1 / 1 / 06 12 : 00 : 00 AM') AND (ID IS NULL) AND (LW <> 1) AND (LWU <> 'test') I have a range of dates that I want to grab, in there I do not want any records where ID has 6,7,8 and I only want records where LW does not equal 1. UP to this point, it works fine. I get all the records that only return these values. However, the moment I add where LWU does not equal 'test'. it does not return the values I want. Furthermore, why can I not put this whole string into one and clause? I never understood why I had to create a second line following OR. the longer this query gets the more I get confused. Any help?
