Nulls In Columns Additions When 1 Or More Column Values Is Blank
Jun 4, 2007
I am running into an issue when adding data from multiple columns into
one alias:
P.ADDR1 + ' - ' + P.CITY + ',' + ' ' + P.STATE AS LOCATION
If one of the 3 values is blank, the value LOCATION becomes NULL. How
can I inlcude any of the 3 values without LOCATION becoming NULL?
Example, if ADDR1 and CITY have values but STATE is blank, I get a
NULL statement for LOCATION. I still want it to show ADDR1 and CITY
even if STATE is blank.
Thanks

I have a table containing a VARCHAR(9) NOT NULL column. Every record in the column will have alength of 9 if a record exists.
WHEN I run the following query on the table
SELECT Column_A
FROM Table1
WHERE Column_A <> ''
I get no records returned. However, I know that when I run a query
SELECT DATALENGTH(Column_A)
FROM table1
WHERE DATALENGTH(Column_A) <> 9
I have used Datalength instead of LEN because LEN does not return the length of a space character.
I get records amny records. When I copy an individual record from the column, it shows that a space character is in the record.
Does anyone know whay this is happening?

I have a table where different types of values are stored in one field, but I need to seperate them into different fields based on a value in another field.
For (hypothetical) example:
There is an existing table with following info in three columns:
userid record recordtag
1 joe 1
1 j 2
1 jr 3
2 bob 1
2 a 2
2 sr 3
where recordtag indicates (1 for first name, 2 for middle initial, 3 for suffix)
I need to query these records for a report so it the output is:
userID firstname middleinitial suffix
1 joe j jr
2 bob a sr
What's the most efficient approach to create a query that will give me desired results? I have managed to create a very complex query that derives tables for each column I want to create and queries off of that derived table for the 'record' value based on the 'recordtag' values for a given 'userid'. The query is extremely slow, so I know there's some better way out there to get the results I want. Any help would be greatly appreciated. Thanks.

Basically I need to get the SUM of the sum of three columns and all three columns have nulls. To make it more complicated, the result set must return the top 20 in order desc as well.
I keep facing different issues whether I try and use Coalesce, IsNull, Sum, count, anything. My query never returns anything but 0 or NULL regardless of if I am trying to build a CTE or just use a query.
So I'm using Col A to get the TOP 20 in order (which is fine) but also trying to add together the sums of Col A + Col B + Col C for each of the twenty rows...

Table1
Col1 Col2 Col3
-----------------------------------------------------------
P3456 C935876 T675

And the outcome that I want is:
CombinedValues(ColumnName)
----------------------------------------------
P3456 - C935876 - T675
P5555 - C678909 - T8888
where CombinedValues column contains values of coulmn 1,2 & 3 seperated by '-'
So is there any way to achieve this?

How do I write a query using the split function for the following requirement.I have a table in the following way
Identity Name Col1 Col2 Col3
1 Test1 1,2,3 200,300,400 3,4,6
2 Test2 3,4,5 300,455,600 2,3,8
I want an output in the following format
Identity Name Col1 Col2 Col3
1 Test1 1 200 3
1 Test1 2 300 4
1 Test1 3 400 6
2 Test2 3 300 2
2 Test2 4 455 3
2 Test2 5 600 8
If you see the data, first element in col1 is matched to first element in col2 and 3 after splitting the string.

I have a table #vert where I have value column. This data needs to be updated into two channel columns in #hori table based on channel number in #vert table.
CREATE TABLE #Vert (FILTER VARCHAR(3), CHANNEL TINYINT, VALUE TINYINT)
INSERT #Vert Values('ABC', 1, 22),('ABC', 2, 32),('BBC', 1, 12),('BBC', 2, 23),('CAB', 1, 33),('CAB', 2, 44) -- COMBINATION OF FILTER AND CHANNEL IS UNIQUE
CREATE TABLE #Hori (FILTER VARCHAR(3), CHANNEL1 TINYINT, CHANNEL2 TINYINT)
INSERT #Hori Values ('ABC', NULL, NULL),('BBC', NULL, NULL),('CAB', NULL, NULL) -- FILTER IS UNIQUE IN #HORI TABLE
One way to achieve this is to write two update statements. After update, the output you see is my desired output
UPDATE H
SET CHANNEL1= VALUE
FROM #Hori H JOIN #Vert V ON V.FILTER=H.FILTER
WHERE V.CHANNEL=1 -- updates only channel1
UPDATE H
SET CHANNEL2= VALUE
FROM #Hori H JOIN #Vert V ON V.FILTER=H.FILTER
WHERE V.CHANNEL=2 -- updates only channel2
SELECT * FROM #Hori -- this is desired output
my channels number grows in #vert table like 1,2,3,4...and so Channel3, Channel4....so on in #hori table. So I cannot keep writing too many update statements. One other way is to pivot #vert table and do single update into #hori table.

Here's a question I though would be common but can't find an answer to!
My select statement, which pulls from SQL Server tables, has a column which allows nulls. When I try to add a parameter to this column, it no longer returns rows that have null in that column when I test it with the default value of %. I want it to return all the records.
SELECT Jobs.JobID, Jobs.JobName, Engineers.Engineer FROM Jobs LEFT OUTER JOIN Engineers ON Jobs.AccountManager = Engineers.ID WHERE (Engineers.Engineer = @Engineer)
Parameter is;ConvertEmptyStringToNull = TrueDefaultValue = %Direction = InputName = EngineerQueryStringField = EngineerSize = 0Type = Empty
When I run this I get no records! Isn't % suppose to return anything including nulls?

I am new at replication and it has been going well, but have more of an information question that a problem. Basically I have transactional replication without updates. So i am pushing from the publisher to the subscriber only. I have added a table to the publisher side, and it is not replicating to the subscriber. Data pushes fine. I have read about reinitializing, adding article, etc. I do not know which is the way to go, I need it to happen automatically.
Which way and how? Any help is appreciated greatly.

Hi ,
If asked to find all the columns across tables which contains any NULL or blank value then what could be the best approach ?
I am sure there must be a way other than checking each column of each table .
Can anyone help me out in this .

Hi Guys.
I have a problem. I have two feilds in a table. Both of them are (int). I want to be able make sure the same number is not put in both columns for each row. Both colums have to be a different number, and also if one is null, the other cannot be. How do I go about enforcing this policy?
For Example:
This is what I want
ID Column1 Column2
--- -------- ---------
1 5 8
2 5 7
3 null 10
4 6 2
This is what I DO NOT want:
ID Column1 Column2
--- -------- ---------
1 5 5
2 5 5
3 7 7
4 null null
I created a unique constraint between the 2 columns, but it still allows dups within the row. Please help me.

Hi,
I have an SSIS Package. I am using script component to loop through input columns and their values. I am not able to do Null checking. The code is as below. In place of dashes , I want to do null checking but am not able to do. I tried vbNull, IsNull, TypeOf, System.dbNull but nothing is working. I guess am missing something here. Can anyone help me with this.
For Each column In Me.ComponentMetaData.InputCollection(0).InputColumnCollection
columnValue = rowType.GetProperty(column.Name)
If Not --------------- Then
RowData += ((FormatElement(column.Name) + ReplaceSpecialChars(columnValue.GetValue(Row, Nothing).ToString()) + FormatElement(column.Name, True)))
End If
Next
Thanks in Advance.

Hi there,
I'm trying to unpivot a table in SSIS: The pivoted table basically looks like
ID DATE1 TEXT1 DATE2 TEXT2
----------------------------------
ID1 D1 T1 D2 T2
...
The unpivoted result looks like
ID DATE TEXT
-------------------
ID1 D1 T1
ID1 D2 T2
€¦
It works, but the one problem I am facing is: If D1 IS NULL in the pivoted table then D1 in the unpivoted table contains some strange value that is neither NULL nor a valid datetime. In a data viewer I get the in the DATE field "Fehler: Die Parameter Year, Month and Day beschreiben eine nicht darstellbare Datetime." (i. e. "Error: The parameters Year, Month and Day form an invalid datetime."). The loading of the OLE DB target yields an error because the DATE value cannot be converted to a valid datetime.
Anybody having a solution to this?

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.
So its coming out like this.....
Bu1 BU2 BU3 BU4 BU5
L5 L4 L3 L2 L1
L4 L3 L2 L1
L3 L2 L1
L5 L4 L3 L2 L1
So whats the easiest way to move everything along to fill in the blanks, but move the blanks to the end - so it would be more like this:
Bu1 BU2 BU3 BU4 BU5
L5 L4 L3 L2 L1
L4 L3 L2 L1
L3 L2 L1
L5 L4 L3 L2 L1

We have SharePoint list which has, say, two columns. Column A and Column B.
Column A can have three values - red, blue & green.
Column B can have four values - pen, marker, pencil & highlighter.
A typical view of list can be:
Column A - Column B
red  - pen
red - pencil
red - highlighter
blue - marker
blue - pencil
green - pen
green - highlighter
red  - pen
blue - pencil
blue - highlighter

We are looking to create a report from SharePoint List using SSRS which has following view:
          red   blue  green
  pen       2    0    1
  marker    0    1    0
  pencil      1    3    0
  highlighter  1    1    1Â
We tried Sum but not able to display in single row.

I have been trying for some time to create a columnar report where certain columns can be hidden as requested by the user. I have tried placing the complete column set in the report, and then hiding a subset of columns, but blank pages are produced when rendered to PDF since the report body does not appear to shrink as columns are hidden and justify themselves to the left. I have tried a table, list, and matrix to no avail...
Does anyone know of a workaround, a trick, or even a hack that may accomplish what I am after?
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.Â
I have searched around online and tried a few things using the Replace funtion in Derived columns but no dice so far.Â

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.

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.

Hi,
I have multiple columns in a Single Table and i want to search values in different columns. My table structure is
col1 (identity PK)
col2 (varchar(max))
col3 (varchar(max))
I have created a single FULLTEXT on col2 & col3.
suppose i want to search col2='engine' and col3='toyota' i write query as
SELECT
TBL.col2,TBL.col3
FROM
TBL
INNER JOIN
CONTAINSTABLE(TBL,col2,'engine') TBL1
ON
TBL.col1=TBL1.[key]
INNER JOIN
CONTAINSTABLE(TBL,col3,'toyota') TBL2
ON
TBL.col1=TBL2.[key]
Every thing works well if database is small. But now i have 20 million records in my database. Taking an exmaple there are 5million record with col2='engine' and only 1 record with col3='toyota', it take substantial time to find 1 record.
I was thinking this i can address this issue if i merge both columns in a Single column, but i cannot figure out what format i save it in single column that i can use query to extract correct information.
for e.g.;
i was thinking to concatinate both fields like
col4= ABengineBA + ABBToyotaBBA
and in search i use
SELECT
TBL.col4
FROM
TBL
INNER JOIN
CONTAINSTABLE(TBL,col4,' "ABengineBA" AND "ABBToyotaBBA"') TBL1
ON
TBL.col1=TBL1.[key]
Result = 1 row
But it don't work in following scenario
col4= ABengineBA + ABBCorola ToyotaBBA
SELECT
TBL.col4
FROM
TBL
INNER JOIN
CONTAINSTABLE(TBL,col4,' "ABengineBA" AND "ABB*ToyotaBBA"') TBL1
ON
TBL.col1=TBL1.[key]
Result=0 Row
Any idea how i can write second query to get result?
