Placing A Sum In A Table Header Column
Jan 30, 2007I have been requested to add the sum of an interger field to the table header. I have the sum in the footer (which is very easy to do), but I cannot get the sum to appear in the table header.
I then set-up the stored procedure to run the sum, and place it into a dummy field. I still cannot add this field to the table header. Instead of printing the data for the dummy field (the correct total), it instead prints the actual field name on the report.
Is there anyway to place a sum in a table header on a SQL Server Report?
Let me know.
Thank you,
T.J.

Changing The Column From NULL To NOT NULL
Feb 28, 2008Hi all,
One of my columns is the table has some Null values, and I Would like to stop having NULL values into that column any more.
I know, If I alter the column to NOT NULL will throw me an error, since it does a batch update.
Is there any way to achieve this...
Thanks...

T-SQL (SS2K8) :: Cannot Define Primary Key Constraint On Nullable Column But Column Not Null
Sep 30, 2014We have a database where many tables have a field that has to be lengthened. In some cases this is a primary key or part of a primary key. The table in question is:-
/****** Object: Table [dbo].[DTb_HWSQueueMonthEnd] Script Date: 09/25/2014 14:05:09 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
SET ANSI_PADDING ON
GO
CREATE TABLE [dbo].[DTb_HWSQueueMonthEnd](
[Code] ....
The script I am using is
DECLARE@Column varchar(100)--The name of the column to change
DECLARE@size varchar(5)--The new size of the column
DECLARE @TSQL varchar(255)--Contains the code to be executed
DECLARE @Object varchar(50)--Holds the name of the table
DECLARE @dropc varchar(255)-- Drop constraint script
[Code] ....
When I the the script I get the error message Could not create constraint. See previous errors.
Looking at the strings I build
ALTER TABLE [dbo].[DTb_HWSQueueMonthEnd] DROP CONSTRAINT PK_DTb_HWSQueueMonthEnd
ALTER TABLE [dbo].[DTb_HWSQueueMonthEnd] Alter Column [Patient System Number] varchar(10)
ALTER TABLE [dbo].[DTb_HWSQueueMonthEnd] ADD CONSTRAINT PK_DTb_HWSQueueMonthEnd PRIMARY KEY NONCLUSTERED ([Patient System Number] ASC,[Episode Number] ASC,[CensusDate] ASC)
WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, SORT_IN_TEMPDB = OFF, IGNORE_DUP_KEY = OFF, ONLINE = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
They all seem fine except the last one which returns the error
Msg 8111, Level 16, State 1, Line 1
Cannot define PRIMARY KEY constraint on nullable column in table 'DTb_HWSQueueMonthEnd'.
Msg 1750, Level 16, State 0, Line 1
Could not create constraint. See previous errors.
None of the fields I try to create the key on are nullable.

View 1 Replies View RelatedIntegration Services :: SSIS Package - Replacing Null Values In One Column With Values From Another Column
Sep 3, 2015I have an SSIS package that imports data from an Excel file, replaces any value in Excel that reads "NULL" to "", then writes the data to a couple of databases.
What I have discovered today, is I have two columns of dates, an admit date and discharge date column, and what I need to do is anywhere I have a null value in the discharge date column, I have to replace it with the value in the admit date column.Â
I have searched around online and tried a few things using the Replace funtion in Derived columns but no dice so far.Â

Hi everyone, I have a small dilema here. I am running SSRS 2000, and I have a report that is grouped by Part Number. I have =Fields!Formula.Value < .1 so I can view only what is greater than .1 Well, my problem is that when I put it under the group Visibility properties, it does not pull all the data. and if i put it under detail Visibility. It does show me everything but any Part Number that is less than .1 shows just the part number but no detail. How can I make my report show all my data but without leaving data out????
Thanks ahead of time,

Placing Sp_executesql Data Into A Var
Jan 27, 2004I have a stored procedure that takes various parameters and performs simple selects using these. A quick summary of the db structure this is working on would be :
lookup_table1
table1_id
description
lookup_table2
table2_id
description
This stored procedure attempts to select the given description from the given table and return the id, if the id isnt present it then inserts the new value and returns the new id.
Now I have this working, ish, but the problem that I have is that in the case of a new insert the procedure returns two datasets, an empty one (as the initial select returned no results) and another with the id of the newly inserted value.
This procedure as it stands right now
CREATE PROCEDURE aida_lookup
@lookup_table varchar(255),
@lookup_id_name varchar(255),
@lookup_description_col varchar(255),
@lookup_value varchar(255)
AS
declare @sql nvarchar(2048)
--
-- Check if the given lookup value exists in the give table / column
--
set @sql ='SELECT ' + @lookup_id_name + ' FROM ' + @lookup_table + ' WHERE ' + @lookup_description_col + ' = ''' + @lookup_value + ''''
EXECUTE sp_executesql @sql
if (@@rowcount = 0) goto new_value
if (@@error <> 0) goto on_error
return(1)
--
-- Insert new lookup value into the given table / column
--
new_value:
-- NEED TO CLEAR PREVIOUS NULL SELECT
begin transaction
set @sql = 'INSERT INTO ' + @lookup_table + ' (' + @lookup_description_col + ') VALUES (''' + @lookup_value + '''); SELECT SCOPE_IDENTITY()'
execute sp_executesql @sql
if (@@error <> 0) goto on_error
commit transaction
return(1)
--
-- Error handler
--
on_error:
rollback transaction
return (0)
GO
The problem being is that if the value is inserted as a new value I need to remove the empty dataset so that regardless of how the procedure is run, it will always return the id at position row 0 column 0.
My attempted solution was to declare a @temp var and place the return value of sp_executesql into this, and if it wasnt null then return it, and if it was then proceed to insert, e.g.
declare @temp int
...
SET @temp = EXECUTE sp_executesql @SQL
if (@@temp = null) goto new_value
SELECT @temp
return(1)
Obviously this doesnt work, so I am open to suggestions. To be completly honest I have run out of hair to rip out and I am sure this can probably be done in a much more elegant fashion, so any help will be greatly appreciated

Best Way To Add Column Not Null
Jun 5, 2007Hi.I've read up on this, and have something that works, but I was wondering ifthere is anything I'm overlooking with this.Situation is:I have a bunch of tables.. I need to modify table2 as part of an upgrade of adatabase schema.I am using T-SQL scripts to do the trick which I'm writing myself.I need to add a new varchar(8) column that is not null to the primary key.I have a default I would like to use for the initial ddl modification.I want to get rid of the default after the modification is complete, but leavethe column not null for future operations...(Some if the code I'm using I took from one of Erlands posts.. hope I'm notabusing it).Here is the code I'm using now.. it basically adds the column 'institution_id'as not null along with a default.Then I jump through a couple of hoops trying to get rid of the default.Finally I setup the primary key again.I can only feel I'm supposed to be maybe using a constraint column with a nameto do this easier/more properly.set @dynamicsql = ' alter table institution_xref add institution_idvarchar(60) not null default ''' + @default_institution_id + ''' 'EXEC (@dynamicsql)set @dynamicsql = ' alter table institution_xref alter columninstitution_id varchar(60) not null 'EXEC (@dynamicsql)select @institution_iddefault = object_name(cdefault) from syscolumnswhere id = object_id('institution_xref') and name = 'institution_id'exec(' alter table institution_xref drop constraint ' +@institution_iddefault)set @dynamicsql = ' alter table institution_xref drop constraintinstitution_xref_pk 'EXEC (@dynamicsql)set @dynamicsql = ' alter table institution_xref with nocheck addconstraint institution_xref_pk primary key clustered (originalcode,institution_id) 'EXEC (@dynamicsql)thanksJeffJeff Kish

NULL Column Bug?
Mar 16, 2007It is issues like this that drive a programmer insane! I am trying to figure out if I am missing something here.
I have a query like this:
SELECT CL.DivisionId FROM CompanyLabels CL, BusinessRules B WHERE CL.CompanyLabelId = B.CompanyLabelId
In my table, DivisionId is nullable and equal to NULL.
In my VS.2005 Mobile 5 application, this line is giving me fits:
if (dr["DivisionId"] != null) { MessageBox.Show(dr["DivisionId"].ToString().Length.ToString()); divisionId = Convert.ToInt32(dr["DivisionId"].ToString()); }
DivisionId passes the null check and is blank. The message box returns "0" and of course, I get a FormatError on the conversion.
I have also tried DBNull in place of null. Is there a special System.Data.SqlServerCe NULL value in the SQL CE framework that I should be using? Am I completely forgetting something here?
Thanks!

Placing Tempdb BACK On Disk
Jul 23, 1998Our development server is limited on RAM and I have been asked to increase Tempdb. I made the decision to put it back on disk; something I have done dozens of times before. I have used the Enterprise Manager`s GUI interface and I have manually typed in the SQL using ISQL/w, both ways have resulted in the same error message.
Microsoft SQL-DMO
Error 5016: [SQL Server] Incorrect database name or device name(s).
I have dropped the old and created new database devices (with different names) and I still receive the error message. I have even tried rebooting with Tempdb back in RAM and on disk 1t 2MB (which works). And yes, I HAVE checked my typing.
I would GREATLY appreciate any ideas on what may be wrong. The system is 6.5 with SP4 on Win NT with SP3. I inherited the system, so I am not certain what the hisory is.
Thanks,

Placing Data And Log Files Seperately
Mar 4, 2004Hi, Gurus, I am running SQL-Server 2000 on SCSIIs with Raid-5. Three disks. I see only one Logical Disk with 3 partitions. Since it's recommended to have Log files seperate to Data files physicially, currently both exist in the D-Drive. How can it be accomplished?
Another question for ur kind suggestion. I have a merge-repl setup. Publisher and distributor at the same machine. One subscriber over the internet. Replication works through VPN rather that FTP. Whenever i apply SNAPSHOT it takes more that 12 hrs to replicate the 2 GB DB. Although VPN is more secured but the tunneling makes the replication rather slow i guess. Will there be a major difference if i open the default port of ftp on the ISA and change the subscriber to get the SNAPSHOT as Anonymous Subsciption. I mean What's better, Security VS Performance. During the SNAPSHOT the Web-users running on the Subscriber wait for the latest data which is very much annoying.
Another question please, I wanna replace the current publisher-DB machine with a new Hardware-Machine. I don't wanna lose Replication and re-running the SNAPSHOT. Is it possible to retain the publication by restoring the Master, Publication and Distributor respectively on the new machine. The new machine will have the same Operating system name and configuration.
Regards!!
Placing A Web Link In An Email Body
Nov 28, 2007I'm generating emails using sp_send_dbmail. Everything works perfectly except for one thing. In the body of the email I need to show a link to a web page (eg http://myweb/login.aspx).
The problem is that the received email shows the "link" as plain text, ie it is not a clickable link. I've tried adding char(13) (and char(10) and both) after the link text but that doesn't help.
Is there a way to make the link text a real link when received by Outlook? (All recipients will be using Outlook if that helps).
Thanks,

Placing Textboxes In Headers Of Reports
Jan 4, 2008Hi,
After exporting the report the column headers in the rreport should not scroll, it has to fix with report headers. If i move the column headers to report header the columns are merging in excel, some columns are hiding.
For ex: I have 10 columns, it has to take from A to K but it is taking A to P. one column is occupying two columns. how to avoid this merging and how to place the column headers in the report header.

Problem With Isnull. Need To Substitute Null If A Var Is Null And Compare It To Null And Return True
Sep 20, 2006Hey. 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)

-Put 0 as a default value for each column, like that I do not have to use coalesce when I do SUM for each column.
-Leave the default value null but I will have to use coalesce.
In term of performance, what is the best solution?
Thanks
DB Design- NULL Column!!
Oct 28, 2005Hello FriendsSuppose I'm designing one database table- ABC master and it has fields like field1, field2........field5. From these fields, Field1 is PK and 2 & 3 and mandatory. So while creating this table, is it necessary to specify the field 2 & 3 as NotNull in Null column.If I specify them as Null then does it effect aby thing. As i know that before saving the data to the database the programming logic checks whether the mandatory data entered or not?Reply back..Thanks
View 3 Replies View RelatedHow To Get Column Names Which Are Not Null
Jul 12, 2002Hi,
I have a table in which out of 20 columns, there will be data only in a few columns. So, I need to find those column names which have data in them. I was able to do it using the information_schema and using a cursor to loop through all the column names and find out which columns have data in them. But i need to know if there is a more efficient way of doing this without using the cursor. Can somebody please let me know how this can be done without using a cursor? Thank you.

Code:
SELECT lname + ',' + space(1) + fname + SPACE(1) + mname as FullName
