Question in review today is Creating a Report showing the FName, LName of all Employees not Specified in a region; I would assume "No Value to be Null" Correct?
Or is there another way for me to do this?
This is what I have so far...What am I missing that this is not showing me results?
Select Firstname, Lastname, Region
From Employees
WHERE Region LIKE 'null%';
I have a nested query that retrieves a min value. I would like to know how do i retrieve the corresponding time with that.
my data looks like this
valuevaluetime
1212/31/14 14:51
12.42/19/15 23:30
[highlight=#ffff11]10.92/21/15 6:40[/highlight]
13.21/25/15 20:47
My min value is 10.9 and i need the date 02/21/15
my nested query is as follows
( select min(cast(f.valuestr as float))
from bvfindings f
where f.ObjectName = 'Hematocrit'
and f.sessionid = s.sessionid
and f.ValueTime > s.open_time)
the above returns me the 10.9
i modified the query
select min(cast(f.valuestr as float)),
f.valuetime
from bvfindings f
where f.ObjectName = 'Hb'
but i get all values then.
I have two tables, a dates table and a values table. They are joined on the date column.The date table has a range, say from today as far as 20 days from now, incrementing by 1 day each row.The values table may have a row for a day, and may not. If the day has a value I want to display that value.If the day does not have a value in the values table I want to display the last known value.
I think this can be done with windowing functions in a set based manner but have not been able to work it out. I have done it procedurally but im not happy with that at all, and really want to see if this is possible in a set based manner.Below is some simplified code to allow testing with sample data.

The following t-sql 2012 works fine in sql management studio. However when I place it in a .net 2010 web form application, I am told the sql does not work when the parameter values are null. Thus can you tell me what I can change in the sql below that will accept null as 3 possible input values?

I am working on SSIS Packages. I have raw files in which data is in text qualifier.
When I am trying to load files into database it's throwing me error when there is no values in text qualifier.
For Example. "Others","0","0"," "," "
If I have the value above in raw files. SSIS Package throwing me error in " " this column.
Saying Data Conversion failed.
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 need to provide a minimum value over a 12 hour time range of data. I'm struggling with performance issues due to the amount of data. Currently I log about 100 devices reporting once per minute into a table. Also about once per minute I need to pull the minimum value reported for each device in the last 12 hours. Currently I'm maintaining a separate table with entries for just the last 12 hours and just performing a Select Min(Temp) Where DeviceID=x, but it already holds about 700,000 records at any given time. The number of devices will increase substantially and this will no longer be viable.

In our Microsoft Dynamics Nav instance we have a Sales Header Archive table - into which copies of the Sales Header are placed, with 3 items forming the compound key:
Document Number
Version
Occurrence number
so if doc 1 is archived, then the records would be
Doc# | Version | Occurrence #
1 | 1 | 1
When a second copy is archived a new record is added:
Doc# | Version | Occurrence #
1 | 1 | 1
1 | 1 | 2
and then when maybe a 3rd version is archived a 3rd entry added
Doc# | Version | Occurrence #
1 | 1 | 1
1 | 1 | 2
1 | 2 | 2
This is for EACH document and I now need to retrieve the dataset which is the latest version of each document... but I'm drawing a blank!
If I
select [Doc#], max([Version]) as [V], max([Occurrence #]) from (table) group by [Doc#]
then I get the distinct list of docs, but I now need to use this list to select the records which match this criteria, from this table.
How do I select just these?
I thought (wrongly) that I could simply say:
Select * from Invoice Table where
Invoice.[Doc#], Invoice.[V], Invoice.[Occurrence #] in
(select [Doc#], max([Version]) as [V], max([Occurrence #]) from (table) group by [Doc#])
I have a table that lists math Calculations with "User Friendly Names" that look like the following:
([Sales Units]*[AUR])
([Comp Sales Units]*[Comp AUR])
I need to replace all the "User Friendly Names" with "System Names" in the calculations, i.e., I need "Sales Units" to be replaced with "cSalesUnits", "AUR" replaced with "cAUR", "Comp Sales Units" with "cCompSalesUnits", and "Comp AUR" with "cCompAUR". (It isn't always as easy as removing spaces and added 'c' to the beginning of the string...)
The new formulas need to look like the following:
([cSalesUnits]*[cAUR])
([cCompSalesUnits]*[cCompAUR])
I have created a CTE of all the "Look-up" values, and have tried all kinds of joins, and other functions to achieve this, but so far nothing has quite worked.
How can I accomplish this?

DECLARE @Synonyms TABLE

Following SQL Statement is from BOL 7.0 and it doesn't return any data. But when I change the where clause to "WHERE advance IS NULL" it works.

Hi
I am importing an excel spreadsheet into tables in a sql server database using dts. I have one row of information filled out in the excel spreadsheet, but when the dts runs, it imports the information plus 5 extra rows filled with nulls ino the table.
Does anyone know how to fix this?
Thanks
I am trying to create a report using Reporting Services.
My problem right now is that the way the table is constructed, I am trying to pull 3 seperate values i.e. One is the number of Hours, One is the type of work, and the 3rd is the Grade, out of one column and place them in 3 seperate columns in the report.
I can currently get one value but how to get the information I need to be able to use in my reports.
So far what I've been working with SQL Reporting Services 2005 I love it and have made several reports, but this one has got me stumped.
Any help would be appreciated.
Thanks.
I might not have made my problem quite clear enough. My table has one column labeled value. The value in that table is linked through an ID field to another table where the ID's are broken down to one ID =Number of Hours, One ID = Grade and One ID= type of work.
What I'm trying to do is when using these ID's and seperate the value related to those ID's into 3 seperate columns in a query for using in Reporting Services to create the report
As you can see, I'm attempting to change the name of the same column 3 times to reflect the correct information and then link them all to the person, where one person might have several entries in the other fields.
As you can see I can change the names individually in queries and pull the information seperately, it's when roll them altogether is where I'm running into my problem
Thanks for the suggestions that were made, I apoligize for not making the problem clearer.
Here is a copy of what I'm attempting to accomplish. I didn't have it with me last night when posting.

these values are inserted throug ODBC with VC++,
in the case of the DESCRIPTION Column, i´m sending null strings CString(""). this value will be filled after.
What happens is that, when i query the database to show the records in this table, the database shows, for example:

I have some VB.NET code to retrieve data from an SQL Server database and display it. The code is as follows: -------------------------------------------------------------------------------------------------------
sw_calendar = calendarAdapter.GetEventByID(cid)
If sw_calendar.Rows.Count > 0 Then
lblStartDateText.Text = sw_calendar(0).eventStartDate
lblEndDateText.Text = sw_calendar(0).eventEndDate
lblTitleText.Text = sw_calendar(0).title
lblLocationText.Text = sw_calendar(0).location
lblDescriptionText.Text = sw_calendar(0).description
Else
lblStartDateText.Text = "*** Not Found ***"
lblEndDateText.Text = "*** Not Found ***"
lblTitleText.Text = "*** Not Found ***"
lblLocationText.Text = "*** Not Found ***"
lblDescriptionText.Text = "*** Not Found ***"
End If
-------------------------------------------------------------------------------------------------------
If all of the fields in the database has values, everything works ok. However, if the title, location or description fields have a null value, I receive the following error message:
Unable to cast object of type 'System.DBNull' to type 'System.String'.
I've tried a bunch of different things such as:
Adding ".ToString" to the database field,
Seeing if the value is null: If sw_calendar(0).description = system.DBnull.value...
...but either I get syntax errors in the code, or if the syntax is ok, I still get the above error message.
Can anyone help me with the code required to trap the null within the code example I've provided? I'm sure there are other, and better, ways to code this, but for now I'd really like to get it working as is, and then optimize the code once the application is working (...can you tell I have a tight deadline )
Thanks,

If myDateTimeColumn contains a <NULL> value. How do you handle that when reading into a DateTime object in your code?DateTime myDate = Convert.ToDateTime(dr["myDateTimeColumn"]);Does not work, it throws: System.InvalidCastException: Object cannot be cast from DBNull to other types.
I am curious as to what others are doing to handle this?
Anyone know if it's possible to retrieve a parameterized value from dynamically executed SQL???
Code Example
Declare @table varchar(25)
Declare @somevalue varchar(3)
Set @table = 'sometable'
Set @somevalue = 'somevalue'
Declare @sqlBuild varchar(2000)
Set @sqlBuild = 'DECLARE @return varchar(3); ' +
' SELECT @return = COUNT(COLUMNAME) ' +
' FROM ' + @table +
' WHERE ' +
' value = ' + @somevalue
exec (@sqlBuild)
i want to be able to extract the value of @return for later use. this procdure works fine but I need to grab that value somehow.
Any suggestions?
Hello,I am trying to import a CSV file into my SQL Server database, this file was originally generated by another database table (on another server) with the same structure, the table contains two columns of real datatype with Allow Null Value setto true for those columns, the CSV file contains the value NULL for theses columns, I am facing a problem when importing this file. This may be because DTS tries to represent values as strings then to convert them to real datatype which results in transforming the value "NULL" to real, I receive an error message saying.Error during Transformation 'DirectCopyXform' for Row number 1. Errors encountered so far in this task: 1.
TransformCopy 'DirectCopyXform' conversion error: Conversion invalid for datatypes on column pair 8 (source column 'Col008' (DBTYPE_STR), destination column 'zip_longitude' (DBTYPE_R4)).
TransformCopy 'DirectCopyXform' conversion error: Conversion invalid for datatypes on column pair 7 (source column 'Col007' (DBTYPE_STR), destination column 'zip_latitude' (DBTYPE_R4)).How can I work around this problem? Any help would be appreciable
I am stuck on a query where I need to display all the month year values even if the corresponding count_booking values are NULL. The requirement is to display the 13 month year period from current date.
For e.g. if the date exists in the current month then starting from May 15 go all the way back to Apr 14.
My current query works in terms of displaying all the 13 months if the count_booking values exist for all the months. However, if some months are missing the values then those months don't show up.how to display all the months even if the values are NULL ? Query below:
SELECT COUNT(m.BOOKING_ID) AS count_booking, LEFT(DATENAME(MONTH, m.CREATE_DT), 3) + ' ' + RIGHT('00' + CAST(YEAR(m.CREATE_DT) AS VARCHAR), 2)
AS month_name

WHERE (m.CREATE_DT >= DATEADD(m, - 13, GETDATE()))

I have a DTSX package which reads values from a fixed-length text file using a data reader and writes some of the column values from the file to an Oracle table. We have used this DTSX several times without incident but recently the process started inserting NULL values for some of the columns when there was a valid value in the source file. If we extract some of the rows from the source file into a smaller file (i.e 10 rows which incorrectly returned NULLs) and run them through the same package they write the correct values to the table, but running the complete file again results in the NULL values error. As well, if we rerun the same file multiple times the incidence of NULL values varies slightly and does not always seem to impact the same rows. I tried outputting data to a log file to see if I can determine what happens and no error messages are returned but it seems to be the case that the NULL values occur after pulling in the data via a Data Reader. Has anyone seen anything like this before or does anyone have a suggestion on how to try and get some additional debugging information around this error?

I have an Excel spreadsheet (Excel 2003 format) with a column of values. The column is formated to General (although I've tried it formated to text). The values are alphanumeric. However, there are a few values that are completely numeric.
Example:
_ITEMNUMBER_
1-528
K214-5
184PR
45678
As can be seen, the last value is completely numeric. I am importing into a table with one column that is formated as nvarchar(50).
I use dtswizard.exe and do a simple import into the table and the alphanumeric values import just fine but anytime a value is completely numeric it has a NULL value in the table instead of the value that should be there.
I've tried changing the format of the column to nchar, char, etc, etc. Always comes in NULL.
Any ideas?
Hi - I'm new to SSRS/SQL and have a situation I can't figure out. I've tried a number of things, but I'm not sure the best way to return a calculated column based on the structure of my tables.
I have a primary Detail table that tracks product testing results. The Detail records need to be calculated against a "Year" table that contains a set of values by year. This table contains a single record for each year. There isn't a direct key that joins these two tables.
The Detail table looks like:
Record ID: 9999
PO Number: 12345
Date: 12/1/2007
Test Result: 1.52
The Year table looks like:
Record ID: 1
Start Date: 10/6/2007
End Date: 6/14/2008
LowVal1: 1.0
HighVal1: 1.49
Incentive1: .05
LowVal2: 1.50
HighVal2: 1.59
Incentive2: .06
and so on...
The Detail records need to find the correct Year record based on the Detail date, find the correct value within the LowVal - HighVal range based on the Test Result value, and then multiply the Test Result by the correct Incentive value and return that value.
I was able to find the correct LowVal-HighVal range using an Expression in the report column. Now that I need multiple years, I can't figure out the best way to configure the query.
Any suggestions would be appreciated. Thanks in advance!
I created one stored proc, then copied it to create another similar stored proc with just some filtering changes in the second. Now I want to obtain the results from both like this:
ProjFee ProjGross DailyRunRate Var1 InHouse1 InHouse2 GrossGoal Group Name PostedAmount
---------------------------------------------------------------------------------------------------------------------------
Row# 1 from current stored proc
Row # 2 from called stored proc
so something like this I should get in the end for example when both results are combined:
ProjFee ProjGross DailyRunRate Var1 InHouse1 InHouse2 GrossGoal Group Name PostedAmount
---------------------------------------------------------------------------------------------------------------------------
100000 33455 200 300 345555 4455555 5666666 Arizona 56000
103400 22455 900 700 777555 3333555 5444666 Illinois 660000
The first stored proc (CurrentMonthCollections_AZ) attempts to include the results of the second stored proc at the end (CurrentMonthCollections_IL) by calling it and inserting the fields into a temp table.
I was told by Angel to instead convert the second stored proc into a UDF...but having trouble with this.
What is the best approach to get the desired 2 rows back that I need in that fasion?
Here is the code for the 2 stored procs (very long so I will post as as links):
http://www.webfound.net/CurrentMonthCollections_AZ.txt
http://www.webfound.net/CurrentMonthCollections_IL.txt

) from both stored procs.
I don't think UNION is what I want because it will combine stuff...I just want 2 separated rows
I have three variables
DECLARE @QuantityID uniqueidentifier,
@LengthID uniqueidentifier,
@CostID uniqueidentifier
They are sent to the sproc as null. Since they could be null I need to exclude them from posting to a temp table
Example
DECLARE @QuantityID uniqueidentifier,
@LengthID uniqueidentifier,
@CostID uniqueidentifier
SET @CostID = NEWID()
SELECT @QuantityID as ID UNION ALL
SELECT @LengthID UNION ALL
SELECT @CostID
Two values are null. I want those excluded from this table
Here is the example of what I am trying to do:
DECLARE @QuantityID uniqueidentifier,
@LengthID uniqueidentifier,
@CostID uniqueidentifier
DECLARE @Temp as Table (id uniqueidentifier NOT NULL Primary key)
SET @CostID = NEWID()
INSERT INTO @Temp
SELECT @QuantityID as ID UNION ALL
SELECT @LengthID UNION ALL
SELECT @CostID
How do I insert into @Temp only non null values?
I have a custom essbase application/db source that I wish to connect to from SSRS 2005. I have all the required software installed (APS / SP2 .3050) etc.
I can connect to the datasource in SSRS 2005, but when I'm trying to build the query on the cube, I see under the member properties of all dimensions, the following piece of line
"error occurred retrieving child nodes: null"
Also, when I try to drag my Measures into the query section (or any other dimension for that matter of fact, though that defies logic) I get the following error
Cannot perform cube view operation. OLAP error (1260046): Unknown Member PARENT_UNIQUE_NAME used in query
I am new to using ESSBASE with SSRS 2005, and hence cannot make much sense of the above two errors.
Any insight or a re-direction to similar posts with solutions will be greatly appreciated.
thanks for your time,

Hi
can somebody explain me how I can assign a NULL value to a datetime type field in the script transformation editor in a data flow task.
In the script hereunder, Row.Datum1_IsNull is true, but still Row.OutputDatum1 will be assigned a value '0001-01-01' which generates an error (not a valid datetime). All alternatives known to me (CDate("") or Convert.ToDateTime("") or Convert.ToDateTime(System.DBNull.Value)) were not successful.
Leaving out the ELSE clause generates following error: Error: Year, Month, and Day parameters describe an un-representable DateTime.
If Not Row.Datum1_IsNull Then
Row.OutputDatum1 = Row.Datum1
Else
Row.OutputDatum1 = CDate(System.Convert.DBNull)
End If
Any help welcome.
