I am running into an issue when adding data from multiple columns intoone alias:P.ADDR1 + ' - ' + P.CITY + ',' + ' ' + P.STATE AS LOCATIONIf one of the 3 values is blank, the value LOCATION becomes NULL. Howcan I inlcude any of the 3 values without LOCATION becoming NULL?Example, if ADDR1 and CITY have values but STATE is blank, I get aNULL statement for LOCATION. I still want it to show ADDR1 and CITYeven if STATE is blank.Thanks
Hello, I have a simple question. Is it at all possible to replace columns which has nulls with blank spaces for a float data type column. The columns has null values( written)) in it in some rows and has numbers in other rows . I want to remove nulls before copying it to another file. Thanks
I have been away from SQL for a couple of months, and for the life of me cannot work out a simple way to do what i want to do.
select bu1.name,bu2.name, bu3.name, bu4.name, bu5.name from Sale INNER JOIN Sysuser on sale.userid = sysuser.userid INNER JOIN businessunitBU1 on BU1.Businessunitid = sysuser.businessunitid left JOIN businessunitBU2 on BU2.Businessunitid = bu1.parentbusinessunitid left JOIN businessunitBU3 on BU3.Businessunitid = bu2.parentbusinessunitid left JOIN businessunitBU4 on BU4.Businessunitid = bu3.parentbusinessunitid left JOIN businessunitBU5 on BU5.Businessunitid = bu4.parentbusinessunitid
So effectively i am trying to go through the hierarchy to find all the levels. Unforunately not every entry has the same amount of levels.
I'm built a trace in SQL Profiler and I have selected columns "DatabaseName" and "Filename" (among others) to be displayed. When I run the trace, the columns are displayed but the values are blank. The SQLServer 2K version is 8.0.760. Is this a bug or am I missing something?
Replicating from SQL Server 2005 to Oracle 9i Release 2. The source table has NOT NULL specified for all columns. The table contains multiple rows with blank values in one of the NOT NULL columns. When I attempt to replicate this table to Oracle, I'm unable to replicate the rows containing the blank values.
I've followed the directions in the Oracle Subscribers page in Books Online: http://msdn2.microsoft.com/en-us/library/ms151738.aspx
Modify the generated create table script, removing the NOT NULL attribute from any character columns that may have associated empty strings, and supply the modified script as a custom create script for the article using the @creation_script parameter of sp_addarticle Here is the segment of the Publication Script referencing sp_addarticle:
exec sp_addarticle @publication = N'mike_hayes_test_replication2', @article = N'mike_hayes_test_replication', @source_owner = N'bmssa', @source_object = N'mike_hayes_test_replication', @type = N'logbased', @description = N'', @creation_script = 'CREATE TABLE [bmssa].[mike_hayes_test_replication2]( [EXCELCOLUMN] [int] NULL, [TABLENAME] [varchar](40) NULL, [FIELDNUM] [int] NULL , [REFTABLEID] [int] NULL , [MODULETYPE] [int] NULL , [DATAAREAID] [varchar](3) NULL, [RECVERSION] [int] NULL, [RECID] [int] NULL, [BRAND] [varchar](20) NULL )', @pre_creation_cmd = N'drop', @schema_option = 0x00, @identityrangemanagementoption = N'manual', @destination_table = N'mike_hayes_test_replication2', @destination_owner = N'bmssa', @vertical_partition = N'false' GO I added the @creation_script value, and changed the schema_option to 0x00. The problem is that when replication occurs, the table that is created has NOT NULL specified for all columns. I expected that the @creation_script would be executed, (as per the instructions), but that doesn't appear to be the case. Any ideas? Thanks for your help. Mike Hayes
Hi, I have fields in my table which allow nulls. Is it efficient to not insert anything (the field automatically shows up as null in this case) and leave or store some value into it. The field is a smallint field?
I have a query which is returning a different result set when it is run against identical tables in 2 different environments.
The query is like:
Select F.LicenseeID, IsSpecialLicensee from FactTable F left join View_SpecialLicensee SL on F.LicenseeID = SL.LicenseeID
The Create Statement for the view is like
Create View [dbo].[View_SpecialLicensee] as Select LicenseeID, LicenseeName, IsSpecialLicensee = 1 from DimensionLicensee where LicenseeName like '%ibm%' or LicenseeName like '%cisco%' or LicenseeName like '%hp%'
In my test environment, I get the query result I expected: LicenseeID, IsSpecialLicensee 1 , 1 - (where LicenseeName = 'IBM') 2, null - (where LicenseeName = 'Juniper') 3, 1 - (where LicenseeName = 'Cisco') 4, null - (where LicenseeName = 'Microsoft') 5, null - (where LicenseeName = 'Oracle') 6, null - (where LicenseeName = 'Apple')
In my production environment, I get the following query result: 1 , 1 - (where LicenseeName = 'IBM') 2, 1 - (where LicenseeName = 'Juniper') 3, 1 - (where LicenseeName = 'Cisco') 4, 1 - (where LicenseeName = 'Microsoft') 5, 1 - (where LicenseeName = 'Oracle') 6, 1 - (where LicenseeName = 'Apple')
Ideas as to what changed gratefully received.
FYI the production environment which returned the 2nd dataset is SQL2000, I have got the result I expected in both SQL2000 and SQL2005 development environments.
I have a table that displays a bunch of data based on their percentage changes.
There is a parameter (let's say 5%) that the user can set to display only the data which either increased more than 5% or decreased more than 5%.
I want to have a space between the positive changes and the negative changes. ie, to create a blank row between the +'s and the -'s. Does anyone know of a way to do this?
I have 3 paramaters@value1, @value2,@value3 being passed into a stored proc and each of these parameters can be blank. If one of them is blank and the rest of them have some valid values, then I should just exclude the column check for the value that is blank.
For e.g if all my parameters being passed are non- empty then I would do this select * from tblName where column1 like @value1 and column2 like @value2 and column3 like @value3
else if I have one of the parameter being passed as empty, I should ignore that parameter like if@value1 is empty then my sql should be
select * from tblName where column2 like @value2 and column3 like @value3
I don't want to do a dyanmic sql because of rights and security issue. I want it through a stored procedure only.
Also, all the three columns can have null values in the table. Please let me know what is the best possible way to do this. Thanks in advance !.
I am attempting to update a sql db using the update and parameter code in VB.net 2003 through MSDE for a web application. It updates changed data OK, but if the textbox value is deleted, the code does not update the sql db. I am new to this, and I'm sure it is something simple. Here is some sample code.
With cmdCategoriesUpdate .Parameters("@Field1Tag").Value = txtFld1.Text .Parameters("@Field2Tag").Value = txtFld2.Text End With cmdCategoriesUpdate.ExecuteNonQuery() SqlConnection1.Close()

I need to convert a a string column to integer. Before converting, I need to check if it has blank values then convert it to NULL. Someone told me that its easier to convert it to NULL before converting to integer.
When i do a select on my emplee table for rows with null idCompany i dont get any records
I then try to modify the table to not allow a null idCompany and i get this error message:
'Employee (aMgmt)' table - Unable to modify table. Cannot insert the value NULL into column 'idCompany', table 'D2.aMgmt.Tmp_Employee'; column does not allow nulls. INSERT fails. The statement has been terminated.
is there an elegant way to use one equals sign in a where clause that returns true when both arguments are null, and returns true when neither is null but both are equal and returns false when only one is null?
I have two SSIS packages that import from the same flat file into the same SQL 2005 table. I have one flat file connection (to a comma delimited file) and one OLE DB connection (to a SQL 2005 Database). Both packages use these same two Connection Managers. The SQL table allows NULL values for all fields. The flat file has "empty values" (i.e., ,"", ) for certain columns.
The first package uses the Data Flow Task with the "Keep nulls" property of the OLE DB Destination Editor unchecked. The columns in the source and destination are identically named thus the mapping is automatically assigned and is mapped based on ordinal position (which is equivalent to the mapping using Bulk Insert). When this task is executed no null values are inserted into the SQL table for the "empty values" from the flat file. Empty string values are inserted instead of NULL.
The second package uses the Bulk Insert Task with the "KeepNulls" property for the task (shown in the Properties pane when the task in selected in the Control Flow window) set to "False". When the task is executed NULL values are inserted into the SQL table for the "empty values" from the flat file.
So using the Data Flow Task " " (i.e., blank) is inserted. Using the Bulk Insert Task NULL is inserted (i.e., nothing is inserted, the field is skipped, the value for the record is omitted).
I want to have the exact same behavior on my data in the Bulk Insert Task as I do with the Data Flow Task.
Using the Bulk Insert Task, what must I do to have the Empty String values inserted into the SQL table where there is an "empty value" in the flat file? Why & how does this occur automatically in the Data Flow Task?
From a SQL Profile Trace comparison of the two methods I do not see where the syntax of the insert command nor the statements for the preceeding captured steps has dictated this change in the behavior of the inserted "" value for the recordset. Please help me understand what is going on here and how to accomplish this using the Bulk Insert Task.
Can someone tell me what to do if several NULLS are showing up within tables. Is there an easy step to locate all NULLS and delete them within the table?
Can someone provide detailed infromation on how to delete NULLS within tables. I'm new o the SQL side so I hope I have explained what it is that I'm looking to do. Our in house programmer said that the NULLS maybe causing a problem with the software communicating with the SQL Server software.
Hi i am new to SQL, and i have a data base thats got NULLS in it is there a query i can run, which can take the NULL value out ? anything will be greatly appreciated.
Hi,I don't have any specific details as I do not really understand whythis is happening but we have a customer database that we have beenusing and queries on text fields have begun returning empty stringvalues instead of NULL.So for example:SELECT TAB1.DESCRIPTIONFROM TABLE1 TAB1WHERE TAB1.DESCRIPTION IS NOT NULLORDER BY 1may have returned 50 records in the past (purely an example). It isnow returning an additional record first that appears just to be ''.Now I am not too sure where to begin looking into this. ODBCconnections, collation settings? I just am not sure where to begin.The column will not have had '' inserted into it; therefore it shouldbe NULL.I have posted this mainly so I can see if anybody else has seen thissort of behaviour - I cannot see why this has suddenly happened.The collation setting on our server is different to that of thecustomer DB, but this shouldn't make a difference should it?If anybody has any ideas then I can post some more information.Thanks,Paul

HiI am probably going to regret asking this because I'm sure you are going totell me my design is bad 8-) ah well we all have to learn....anywayI often use Nulls as a marker to see if certain tasks have been completed.A typical example would be a column say invoice_valuewhen new work is entered and a new record is appended, I leave theinvoice_value column as NULL, so if I want a View for uninvoiced work Icheck for the invoice_value being equal to NULL, and alternatively if I wantinvoiced work, I check for not null. I did it this way to save putting inanother column that needed to be set to TRUE or FALSE. (I do similar thingselsewhere aswell)so far everything seems to work OK but reading some old stuff on Google Iget the feeling that NULLS should be left alone, have I done wrong?many thanksAndy
Hi,This should be straight forward, but I've searched high and low on the net.I have a FORM which allows me to INSERT data, SQL Server 2005 backend. I populate the all the mandatory fields. But when I click on the Insert button, it won't let me save and says:Column 'PERSONAL_ID' does not allow nullsI'm using tableadapters, business logic layers etc. and pausing clearly shows that the values from the form are being passed to the procedure that I have created "AddNewRecord". And PERSONAL_ID is definitely not NULL! It fails on Line 971: Me.Rows.Add(row)PERSONAL_ID is a primary key which I generate. The pause also shows that for PERSONAL_ID it says " {"Conversion from type 'DBNull' to type 'String' is not valid."}Function AddNewRecord looks like this:<System.ComponentModel.DataObjectMethodAttribute(System.ComponentModel.DataObjectMethodType.Insert, True)> _ Public Function AddNewRecord(ByVal PERSONAL_ID As String, ByVal SURNAME As String, ByVal CHRISTIAN_NAME As String, ByVal SEX As String, _ ByVal FAMILY_POSITION As String, ByVal FAMILY_ID As String, ByVal ADDRESS_1 As String, ByVal ADDRESS_2 As String, _ ByVal ADDRESS_3 As String, ByVal ADDRESS_4 As String, ByVal ADDRESS_5 As String, ByVal ADDRESS_6 As String, ByVal POSTCODE As String, ByVal COUNTRY As String, ByVal ORG_ID As String) As Boolean ' create a new details row instance Dim details As New smDetails.smTbl_DetailsIDDataTable Dim detail As smDetails.smTbl_DetailsIDRow = details.NewsmTbl_DetailsIDRow details.AddsmTbl_DetailsIDRow(detail)...my formview code is this: <InsertItemTemplate> PERSONAL_ID: <asp:TextBox ID="PERSONAL_IDTextBox" runat="server" Text='<%# Bind("PERSONAL_ID") %>' AutoPostBack="True" /> <br /> SURNAME: <asp:TextBox ID="SURNAMETextBox" runat="server" Text='<%# Bind("SURNAME") %>' AutoPostBack="True" /> <br /> CHRISTIAN_NAME: <asp:TextBox ID="CHRISTIAN_NAMETextBox" runat="server" Text='<%# Bind("CHRISTIAN_NAME") %>' /> <br /> SEX: <asp:TextBox ID="SEXTextBox" runat="server" Text='<%# Bind("SEX") %>' /> <br /> FAMILY_POSITION: <asp:TextBox ID="FAMILY_POSITIONTextBox" runat="server" Text='<%# Bind("FAMILY_POSITION") %>' /> <br /> FAMILY_ID: <asp:TextBox ID="FAMILY_IDTextBox" runat="server" Text='<%# Bind("FAMILY_ID") %>' /> <br /> ADDRESS_1: <asp:TextBox ID="ADDRESS_1TextBox" runat="server" Text='<%# Bind("ADDRESS_1") %>' /> <br /> ADDRESS_2: <asp:TextBox ID="ADDRESS_2TextBox" runat="server" Text='<%# Bind("ADDRESS_2") %>' /> <br /> ADDRESS_3: <asp:TextBox ID="ADDRESS_3TextBox" runat="server" Text='<%# Bind("ADDRESS_3") %>' /> <br /> ADDRESS_4: <asp:TextBox ID="ADDRESS_4TextBox" runat="server" Text='<%# Bind("ADDRESS_4") %>' /> <br /> ADDRESS_5: <asp:TextBox ID="ADDRESS_5TextBox" runat="server" Text='<%# Bind("ADDRESS_5") %>' /> <br /> ADDRESS_6: <asp:TextBox ID="ADDRESS_6TextBox" runat="server" Text='<%# Bind("ADDRESS_6") %>' /> <br /> POSTCODE: <asp:TextBox ID="POSTCODETextBox" runat="server" Text='<%# Bind("POSTCODE") %>' /> <br /> COUNTRY: <asp:TextBox ID="COUNTRYTextBox" runat="server" Text='<%# Bind("COUNTRY") %>' /> <br /> ORG_ID: <asp:TextBox ID="ORG_IDTextBox" runat="server" Text='<%# Bind("ORG_ID") %>' /> <br /> <asp:LinkButton ID="InsertButton" runat="server" CausesValidation="True" CommandName="Insert" Text="Insert" /> <asp:LinkButton ID="InsertCancelButton" runat="server" CausesValidation="False" CommandName="Cancel" Text="Cancel" /> </InsertItemTemplate> Any pointers in the right direction would be appreciated.

I have the following query: SELECT tblArticleCategory.ACategoryID, IsNull(ParentCategory, '') + IsNull( ' > ' + ACategoryName, '') AS Category from tblArticlecategory RIGHT OUTER JOIN (SELECT ACategoryName as ParentCategory, ACategoryID from tblArticleCategory WHERE AParentID is null AND aActive=1) AS Parent on parent.ACategoryID = tblArticleCategory.AParentID WHERE tblArticleCategory.AActive=1ORDER BY Category This produces an ordered list of the parent categories and subcategories from the table as long as there is a subcateogry directly below one of the parent categories. If there isn't one directly below the parent category, the parent category is dropped from the list. None of the parents with the NULLS back to back are in the list.

I have a table as part of a replicated database where i need to change the allow nulls value (set it to not allow nulls) but when i try to save the table i get this error.
'CONTACTS' table - Unable to modify table. ODBC error: [Microsoft][ODBC SQL Server Driver][SQL Server]Cannot drop the table 'dbo.CONTACTS' because it is being used for replication.
will i have to stop replication to make the change or is it worse and i have to delete the publication and start all over again?
I have a table with 3 columns. Product, Location and Value. The data looks like this:
NULL NULL 100 Atlanta NULL 50 Atlanta Cookie1 30 Atlanta Cookie2 20 Dallas NULL 120 Dallas Cookie1 80 Dallas Cookie2 40
This table gets filled with a Groupby with Rollup option. The NULLS show subtotals/total. Is there a way to build a query that returns the results with NULLs at the bottom of each section like:
Atlanta Cookie1 30 Atlanta Cookie2 20 Atlanta NULL 50 Dallas Cookie1 80 Dallas Cookie2 40 Dallas NULL 120 NULL NULL 100
I've forgotten how to put a null value in a column of a table where a previous value existed before.
What I mean is if through EM, you look at the data (Open Table -> Return all Rows) and you see a value in a column that is nullable (for example, I want to change a column that has a 'ABC Company' to a NULL value).
How do you that - i've done it in the past ,but cannot remember
