Hello,
I have a stored procedure that accepts a number of different input parameters that populate some variables in my stored procedure.
I want to have this stored procedure return nothing if some of these variables aren't filled out (they are populated by a search page the user fills out).
I'm not very familiar with writing stored procedures, so any help you can give me is appreciated.
Thanks!
Hello,
I have this INNER JOIN that is fine to show all possible combinations. But I need to show only rows that have one or more Null values in tbIntersect.
Should I use nested LEFT JOINT? How?
This is the SQL statement:
sSQL = "SELECT DISTINCT tbCar100.Car100_ID, tbCar100.Description100 AS [Caractéristique 100], " & _
"tbCar200.Car200_ID, tbCar200.Description200 AS [Caractéristique 200], " & _
"tbCar300.Car300_ID, tbCar300.Description300 AS [Caractéristique 300], " & _
"tbCar400.Car400_ID, tbCar400.Description400 AS [Caractéristique 400], " & _
"tbCar500.Car500_ID, tbCar500.Description500 AS [Caractéristique 500], " & _
"tbCar600.Car600_ID, tbCar600.Description600 AS [Caractéristique 600], " & _
"tbCar700.Car700_ID, tbCar700.Description700 AS [Caractéristique 700], " & _
"tbProducts.Prod_ID, tbProducts.PartNumber AS [Part Number] , tbProducts.Description AS [Description] , tbProducts.DateAdded AS [Date] " & _
"FROM tbProducts INNER JOIN (tbCar700 INNER JOIN (tbCar600 INNER JOIN (tbCar500 INNER JOIN (tbCar400 INNER JOIN (tbCar300 INNER JOIN (tbCar100 INNER JOIN " & _
"(tbCar200 INNER JOIN tbIntersect ON tbCar200.Car200_ID = tbIntersect.Car200_ID) " & _
"ON tbCar100.Car100_ID = tbIntersect.Car100_ID) ON tbCar300.Car300_ID = tbIntersect.Car300_ID) ON tbCar400.Car400_ID = tbIntersect.Car400_ID) ON tbCar500.Car500_ID = tbIntersect.Car500_ID) ON tbCar600.Car600_ID = tbIntersect.Car600_ID) ON tbCar700.Car700_ID = tbIntersect.Car700_ID) ON tbProducts.Prod_ID = tbIntersect.Prod_ID " & _
";"
Here is the content of the tbIntersect table:
Car100_ID Car200_ID Car300_ID Car400_ID Car500_ID Car600_ID Car700_ID Prod_ID ID
1 1 1 1 1 1 1 1 1
1 2 1 1 1 1 1 19
1 3 1 1 1 1 1 20
I need to return the rows that have null data, ex: second row because Prod_ID is NULL and third row because Car300_ID is NULL. In fact I need the data from the other joint tables that correspond to these ID fields.
Thanks
I am writing some functions that work on a time series database of prices, ie volatility, correlation. I need to use the SELECT TOP syntax, but cannot do this with a variable, ie 'SELECT @x TOP * from prices'. My solution is to simply have a function for each potential period that will be looked at - 30day_volatility, 60day_volatility, etc. I looked at setting the ROWCOUNT variable but this is not allowed in functions. I haven't posted any DDL because I think the question is general enough - How do I return n ordered rows from a function without using SELECT TOP, or is there a way to use SELECT TOP with a variable that I am not aware of.
Thanks!

Hey. I need to substitute a value from a table if the input var is null. This is fine if the value coming from table is not null. But, it the table value is also null, it doesn't work. The problem I'm getting is in the isnull line which is in Dark green color because @inFileVersion is set to null explicitly and when the isnull function evaluates, value returned from DR.FileVersion is also null which is correct. I want the null=null to return true which is why i set ansi_nulls off. But it doesn't return anything. And the select statement should return something but in my case it returns null. If I comment the isnull statements in the where clause, everything works fine. Please tell me what am I doing wrong. Is it possible to do this without setting the ansi_nulls to off??? Thank you
set ansi_nulls off
go
declare
@inFileName VARCHAR (100),
@inFileSize INT,
@Id int,
@inlanguageid INT,
@inFileVersion VARCHAR (100),
@ExeState int
set @inFileName = 'A0006337.EXE'
set @inFileSize = 28796
set @Id= 1
set @inlanguageid =null
set @inFileVersion =NULL
set @ExeState =0
select Dr.StateID from table1 dR
where
DR.[FileName] = @inFileName
AND DR.FileSize =@inFileSize
AND DR.FileVersion = isnull(@inFileVersion,DR.FileVersion)
AND DR.languageid = isnull(@inlanguageid,null)
AND DR.[ID]= @ID
)
go
set ansi_nulls on
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.

I tried several SQL statements, suspecting it's a syntax issue. All of these failed, but with different error messages. These are the 2 most recent attempts based on posts I was able to locate.
SQLStatement = exec ? = dbo.p_CheckImportFileCreateDate 'GL Account Import', ?, ? output
SQLStatement = exec p_CheckImportFileCreateDate 'GL Account Import', ?, ? output

Variable Name = User::IsNewFile, Direction = Output, DataType = BYTE, Parameter Name = 1, Parameter Size = -1
Result Set is empty.
Expressions is empty.
When I run this in debug mode with this SQL statement ...
exec ? = dbo.p_CheckImportFileCreateDate 'GL Account Import', ?, ? output
... the following error message appears.

When the above is run tbl_ImportFileCreateDate does not get updated, so it's failing at some point when calling the procedure.
When I run this in debug mode with this SQL statement ...

... the tbl_ImportFileCreateDate table gets updated. So I know that data piece is working, but then it fails with the following message.

SSIS package "MyPackage.dtsx" finished: Failure.
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.
I have a flat file with the following columns
SampleID Rep_Number Product Protein Fat Solids
In the flat file SampleID and Product are populated in the first row only, rest of the rows only have values for Rep_Number, Protein, Fat, Solids.
SampleID and Product are blank for the rest of the rows. So my task is to fill those blank rows with the first row that has the sampleID and Product and load into the table.
Hi All,
I am using sql server 2005. I stuck out in a strange problem.
I am using view in my stored procedure, when I run the stored procedure some of the rows get skipped out means if select query have to return 10 rows then it is returning 5 rows or any other but not all, also the records displyaing is randomly coming, some time it is displaying reords 12345 next time 5678, other time 2468.
But if I run seperately the querys written in SP then it returns all the rows. Please give me solution why it is happening like this.
There are indexes in the tables.
Once I shrink the database and rebuild the indexes, from then this problem is happening. I have rebuild the indexes several time, also updated the statistics but nothing improving.
But nothing is improving
I have a conditional split in an SSIS package - one split is where if rows are returned according to a specific rule, then insert those rows into to a Recordset Destinationm which points to a variable of Object type.
How I can use this variable to email fellow users. For example, what I would like is if ANY rows are returned to the Object variable (1 or more), then I would like to execute an email SP that we have on our server.
I managed to transpose rows into columns.
;WITH
ctePreAgg AS
(
select top 500 act_reference "ActivityRef",
row_number() over (partition by act_reference order by act_reference) as rowno,
t3.s_initials "Initials"
from mytablestuff
order by act_reference
[code]...
But what I would love to do next is take each of the above rows - and return the initials either in one column with all the nulls and duplicate values removed, separated by a comma ..
ref, initials
Ag-4xYS
Ag-6xYS,BL
Ap-1xKW
At-2x SAS,CW
At-3x SAS,CW
OR the above but using variable number of columns based on the maximum number of different initials for each row.this is not strictly required, but maybe neater for further work on the view
ref, init1,init2
Ag-4xYS
Ag-6xYS,BL
Ap-1xKW
At-2x SAS,CW
At-3x SAS,CW

I am working on a web application for a company that uses an existing company database. I just found out before the long weekend that a couple hundred of the items in the table aren't completely related.
I am mostly using 2 tables for the project: ItemVersion, ItemVersionRev
ItemVersion has fields: ItemVersion, ItemNumber, RecordID
ItemVersionRev has fields: RecordID, RevNumber
All of the items in the database have ItemNumbers (obviously) and most have revision numbers (RevNumber). One of the functions that I created for my application finds the MaxOfRevNumber. I ran a query on the database and saw that dreaded error screen that read "There is no row at position 0"
The query that I have now simply returns MaxOfRevNumber. Is there a way to program a query to check and see if an ItemNumber has a Revision and depending on the result, return a certain value. For example, if there is not a corresponding RevNumber, then return 0 as the RevNumber?
I have a pivot transform that pivots a batch type. After the pivot, each batch type has its own row with null values for the other batch types that were pivoted. I want to group two fields and max() the remaining batch types so that the multiple rows are displayed on one row. I tried using the aggregate transform, but since the batch type field is a string, the max() function fails in the package. Is there another transform or can I use the aggragate transform another way so that the max() will work on a string?

I am trying to run a sql statement, (without having to run stored procedures), that will lookup a value stored in a Record.field., otherwise ignore the value if it is blank. I have a field tied to a Microsoft Access form - ItemLocation. If the user selects a unique ItemLocation the report will attempt to locate all values within that ItemLocation. If the user decides to leave the field blank, I would like for it to return all values for every ItemLocation. If anyone can help, I would really appreciate it. I will attach code.

I have this program that I want to invoke from SQLServer funny thing is I can invoke this from command line but could not get it to work via 'xp_cmdshell' on this particular server. When I invoke run the following from SQLServer Query Analyser I always get 'NULL' returned.
I tried just running EXEC master..xp_cmdshell 'dir ' and it worked, so I am certain it is not a SQL rights problem.
FYI, I executed the same code on another machine and it worked. I just cannot figure out why it is not working on this one server?
Can anyone help? thanks

Hi,
I have this problem with MS SQL Server.
I have this table 'Request' in which there's 2 fields 'RequestName' and 'DateSubmitted'.
The datatype for 'DateSubmitted' is datetimn.
I have to write a query to extract all the 'RequestName' that falls under each month based on the 'DateSubmitted'.
For example, the table 'Request' has 12 rows, each row ('DateSubmitted') with the month of the year. Like row1 = January, row2 = February etc.
For each month, I have to extract all the 'RequestName' for that month based on 'DateSubmitted' field.
My query is like this:
select RequestName, datename(month, DateSubmitted)as month
from Request where datename(month, DateSubmitted) = 'March'.
By right it should return just one row right?
Instead, it returned me all 12 rows, only one row with value 'March' and the other 11 rows with value 'NULL'. Even if the other 11 rows have value of other months, when i run the above query, it will return me null.
Any help is appreciated.
thanks a million.
Hi all,
I have the situation below. I can't use dual. Thank you for your time.
Example Query:
select name
from employee
where id=1;
Result:
0 rows selected
Wanted Result:
1 row selected
I am trying to return all the names of employees and their managers
this query returns all the employees except for 1
SELECT E.FNAME,E.LNAME,M.FNAME,M.LNAME
FROM EMPLOYEE E,EMPLOYEE M
WHERE E.SUPERSSN=M.SSN
the one that isn't returned has a null SUPERSSN, but when I add in:
OR E.SUPERSSN IS NULL
it returns a row with the name of the employee whose SUPERSSN is null 8 times (where each time the M.FNAME,M.LNAME are other employee names)
How do I ammend the first query to return each employee and their respective manager once, the employee without a manager having null values for the manager name columns?

View 2 Replies View RelatedSQL Server 2000 SP3.Is it possible for the @@ROWCOUNT function to return NULL after astatement? I am troubleshooting a relatively large stored procedure withmultiple SELECT statements and a couple of INSERTs into table variables.Immediately after each statement I save the value returned by @@ROWCOUNT toa local variable. That information eventually is passed back to the clientvia one output parameter, for all statements in the procedure.Occasionally, the value returned via that parameter is NULL. This cannot bereproduced by re-running the SP with the same input parameters.Before doing any further troubleshooting, I would like to rule out thepossibility that @@ROWCOUNT can actually return a NULL under somecircumstances. From searching the archives, it appears that in SQL Server7.0 this could happen in the context of a DML query on a table withtriggers. This is not the case here - the only DML queries are INSERTs intotable variables, all other queries in the SP are SELECTs.Any related information would be appreciated.--remove a 9 to reply by email

asset# 2104, and there's no value in the DriverID field, I need the
rest of the data to display and just have the lblDriverName by
blank. Is that possible?

Sub BindSearchGrid()
Dim searchUnitID As String
Dim searchQuery As String
searchUnitID = tbSearchUnitID.Text
lblIDNum.Text = searchUnitID
searchQuery = "SELECT * FROM Assets " & _
"INNER JOIN Condition ON Condition.ConditionID = Assets.ConditionID " & _
"INNER JOIN Drivers ON Drivers.DriverID = Assets.DriverID " & _
"INNER JOIN Departments ON Departments.DepartmentID = Assets.DepartmentID " & _
"INNER JOIN AssetCategories
ON AssetCategories.AssetCategoryID = Assets.AssetCategoryID " & _
"INNER JOIN Store ON
Store.[Store ID] = Assets.StoreID WHERE RTRIM(Assets.[Unit ID]) = '"
& searchUnitID & "'"
