How To Eliminate The Commas From The End In Sql Query When The Column Value Is Null
Jun 26, 2007
HI
I have three different columns as email1,email2 , email3.I am concatinating these columns into one i.e EMail like
select ISNULL(dbo.tblperson.Email1, N'') + ';' + ISNULL(dbo.tblperson.Email2, N'') + ';' + ISNULL(dbo.tblperson.Email3, N'') AS Email from tablename.
One eg of the output of the above query when email2,email3 are having null values in the table is :
jacky_foo@mfa.gov.sg;;
means it is inserting semicoluns whenever there is a null value in the particular column. I want to remove this extra semicolumn whenever there is null value in the column.
hi, i have null values in my table , i want to eliminate the null values. ie this is my query select p_type from process_general output: 1.BSB HEATER PACKAGE 2.

I am importing an Access .mdb file into MS SQL server, and empty fields where the default value is "", change into NULL. This is a problem when I re-export a result set and have to apply a procedure to clean these values. Is there a way to eliminate this? . . . . and what have I missed?
I have a table with 3 fields. when I type select * from test -- I am getting the results as below.
NAME AGE DEPT
AAA 23 AOD BBB 27 NULL CCC NULL NULL DDD 23 POD
DEPT,AGE are displayed with "NULL" WHEN THERE IS NO value for that field . How can I eliminate this. I need space instead of NULL. When I export to text file there also contains NULL. Let me know how can I eliminate this.
I recently used the REPLACE command, as described in a previous topic on this forum, to remove unwanted commas however I've now got a new problem, the column has become half a mile long. I was asked to raise a new topic and give examples, see below:
CAN ANYONE TELL ME: 1. Why is the column now bigger? 2. How can I redue the size of the column to it's origional size?
I have already attempted to use CONVERT, RTRIM and CAST around the replace command, all give an error.
Example query and result before REPLACE: select ICMAFinInstName,CptyCode from tradedetails
Hi, I have table Article(ID,Title,FAID) I need a query that will select all the Article.ID records where the FAID contains the number of the article ID For exapmle, Article Table content is:
In my employee table has the following fields empid, empFname, empLname, email, city Say it has data like follows: 1, Lucy, Sam, l@some.com, city1 2. Sam, Wite, l@some.com, city2 3. Laura, Mac, l@some.com, city2 4. Stacy, Soo, s@no.com , city1 So in my case I want to show all the column but I want to eliminate multiple email addresses. I tried Distinct but its not workin because here every column is not distinct. So what should I use? In my case I only want to show empID 1, 3, 4. I want to show all the columns
I know I am missing something basic, here. I have a date field in a table. The field is 'allowed Nulls'. When a certain thing happens in the program, the date is filled in. At various times, I need to do a query to find all the rows that have no dates entered.
What do I use in my where clause? SQL server does not like 'where date = null.'
Suppose I have added a xyz bit column in mytable. From now onwards new values inserted in mytable will have 0 or 1 in xyz column but the values that were previously stored will have NULL value in xyz column.
Now I want to write a query in which I will not give xyz parameter always like it can be null or value.
select * from mytable where class='something' and xyz is null
or
select * from mytable where class='something' and xyz = 1
Working in Sql Server 2005,got 3 different table.Need to fetch the list of persons.A person can belong to different categories.When i am using inner join on tables i am getting the duplicate rows because a perosn can belong to different categories.I want that there should be only onoe row for the person and the different categories he belongs to can come up in single field as comma sepatated string Now the results are like this: firstname lastname adress category abc xyz aaa a abc xyz aaa b abc xyz aaa c I want like below: abc xyz aaa a,b,c I am thinking of using cursors in the stored procedure.Can you provide me the solution of this including the stored procedure..
Using c# in the compact framework, is there a way to do a parameterized query for counting the number of records where a specified column is null. I tried all of these, but none of them work:
cmd.Add(new SqlCeParameter("@IntColumn", SqlInt32.Null)); cmd.CommandText = "select count(*) from TableName where IntColumn is not @IntColumn";
cmd.CommandText = "select count(*) from TableName where not IntColumn = @IntColumn";
cmd.Parameters.Add(new SqlCeParameter("@IntColumn", SqlDbType.Int32)); cmd.Parameters["@IntColumn"].Value = SqlInt32.Null; cmdGetNumRead.CommandText = "select count(*) from TableName where IntColumn is not @IntColumn";
I am getting this error: "Cannot insert the value NULL into column 'OrderID', table 'outman.outman.Contact'; column does not allow nulls. INSERT fails." -- But my value is not null. I did a response.write on it and it show the value. Of course, it would be nice if I could do a breakpoint but that doesn't seem to be working. I'll attach a couple of images below of my code, the error, and the breakpoint error.

We 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.
I receive this message when I try to run any report. The reportserver and reportservertempdb databases were upgraded using backup/restore from SQL2000 to SQL2005 on a separate server which is running RS2005 . Please help. Thanks
I 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.
I have searched around online and tried a few things using the Replace funtion in Derived columns but no dice so far.
I have a normal nvarchar(50) field in a table that has a single comma in it but when i read it using OleDbDataReader the comma gets removed. any ideas what i am doing wrong ?
I have an excel file with 2 columns: article art_group kb art,tp,key portal grup,port,li
I have a table in the database called tb_artGroups with the columns
article art_group
Now for each row in the excel i have to write the values after the comma in a new row such as: article art_group kb art kb tp kb key portal grup etc...
How can i do that with SSIS?
Thanks

I am using SQL 2005 and have a query that returns seven columns of data. In one the columns, the results contains commas. For example, one of the results is 'brooke, nick, dustin, and me.jpg'. The results are saved into a .csv file so it can be imported into Excel. The user named the file with the commas and I need to preserve the original file name.
My question: Is there some way to format the data inside of SQL so that when it gets saved as a .csv file, the extra commas don't throw off the column layout?
I don't want to have to manually clean up possibly several hundred rows of data everytime I run the query.
Hi.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
It 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?
I have to use bcp to import two text files everyday for database update. The problem is that some of the character fields that are being imported have double-quotes and/or commas in them. When these are imported into the SQL Server tables additional double quotes are being added into these strings.
Hello Nice simple T-SQL question that will no doubt prove totally uncontroversial :) Anyone know the easiest way to get from:123456789to123,456,789in T-SQL? Currently I cast my int as money, use convert to varchar with style 1 and then lop off the .00. Is there an easier way? Two things before you get all upset and start squealing about front ends:1) These are admin functions that I am running from SSMS. I don't want to go to the bother of creating an application when SSMS is perfectly adequate for what I need (namely to-a-large-degree unformatted result sets).2) I'm not too fussed about it just curious. Ta & tra la!
I have a hierarchy of product categories and I want to string them together to show the complete path (breadcrumbs) to the item. Each category/subcat must be separated buy a comma. The catch is that not all items have the same number of cats/subcats. Here is what I am currently doing, but as you can see, this results in extra commas where the subcats are null.
