Hi,
I need help to build a query that shows me how many columns inside a range on columns are null.
Example: quantity1;quantity2;quantity3;quantity4;quantity5; quantity6;quantity7;
Which columns are null?
Thanks in advance
I'm using an ObjectDataSource in Visual Studio to retrieve records from a SQL Server 2005 database.
I have a very simple dilemma. In a table I have fields FirstName, Surname, Address1, Address2, Address3 etc. None of these are mandatory fields.
It is quite common for the user not to enter data in Address2, Address3, so the values are <null> in the SQL table.
In Visual Studio 2005 I have an aspx form where users can pass search parameters to the ObjectDataSource and the results are returned according to the passed in parameters.
The WHERE clause in my Table Adapter is:WHERE (Address1 LIKE @Address1 + '%') AND (Address2 LIKE @Address2 + '%') AND (Address3 LIKE @Address3 + '%') AND (FirstName LIKE @FirstName + '%') AND (Surname LIKE @Surname + '%')
If, for example, I simply want to search WHERE FirstName LIKE ‘R’, this does not return any results if the value of Address3 is <null>
My query is this: Could someone please show me the best way in Visual Studio 2005 to return records even if one of the Address fields is <null>.
For reference, I have tried: Address3 LIKE @Address3 + '%' OR IS NULLThis does work, however itsimply returns every instance where Address3 is <null> (accounting for about 95% of the records in the database). Thanks in advance Simon
Hi guys,
Working on a MS Access database, I have a table named "myTable" which contains several fields.
I just want to retrieve all the fields (columns) in the myTable, without retrieving Col1 and Col2
What should my SQL string be?
SELECT * (not Col1, Col2) FROM myTable
Thanks in advance for any help.
Aldo.
I need to retrieve columns names(instead of select * from) as single row from table in dynamic way.
i m using following query.
its working fine while using from selected database. but its not working when i m running from different database.
DECLARE @columnnames varchar(max)
select @columnnames = COALESCE(@columnnames,'')+column_name+',' from INFORMATION_SCHEMA.COLUMNS(nolock)
where table_name='table_20141224'
select @columnnames
I need to pass database name dynamically like using by variable.
Is this possible to use variable after from clause. or any other methods?
eg:
DECLARE @columnnames varchar(max)
DECLARE @variable='db_month11_2014'
select @columnnames = COALESCE(@columnnames,'')+column_name+',' from @VARIABLE.INFORMATION_SCHEMA.COLUMNS(nolock)
where table_name='table_20141224'
select @columnnames
Hello,
Is then any type of statement I could run to drop all the columns of a table that have a NULL value thoughout or must this be done manually?
Thanks,

I have a table with 4 column in below
Total amount = 1000
salemancode1 = space
salemancode2 = Staff-99
salemancode3 = space
salemancode4 = staff-88
How I can write a one query statement to do this, we expect to count how many salemancode is not space and count the number of salesman to over the total amount.
total amount / (no_of_saleman) as commission
the result is 1000/ 2 the commission is $500.

I'm trying to figure out marketshares for "preferred" products. I have a table put together by hospital and month of medication use with the totals of each drug dispensed in columns as well.
(example table below)
Hospital Month Drug A Drug B Drug C Drug D
A 7 5 10 58 73
B 7 NULL 26 98 43
etc.
** Drug C and Drug D are the preferred drugs
I'm getting correct preferred % in all cases except when a value is NULL (result is NULL). I'm using an aggregate (sum), which should ignore NULLs, but it ignores NULLs within a column, and not ignoring across columns. I've tried setting concat_null_yields_null off and I'm still getting NULL (since I'm using the plus sign).
This is my admittedly confused select statement, suspect this is where my problem lies (problems with saying "sum", but using "+" as well?):
select a.Hospital,a.month,convert(float,sum(c.Drug_C+d.Drug_D))/convert(float,sum(a.Drug_A+b.Drug_B+
c.Drug_C+d.Drug_D)) as preferred_share
Thanks for any advice!"
Hi,I have some tables where I import data in, lots of field have gotten aNULL value which the application can not handle.Now can I replace each NULL value with '' in a columns with:update <tableset [<column>] = '' where [<column>] IS NULLBut because there are lots of columns this is pretty much work, alsothere are multiple tables.Is there an easy way to replace all NULL values in all columns in atable?Thanks in AdvanceBob
View 2 Replies View RelatedHi all,
I am facing a problem on validating the data from a flat file while inserting the data into the destination table of sql server 2005 database. In my package, i have to validate the input data whether the values are coming as null or not, before inserting into the destination database. The flat file may not contain data for all NOT NULL columns. I have to find out that row(s) and reject the record. If the rows are coming as Null for the Not Null columns, the OLEDB Destination throws OLEDB exception for the constraint.
To resolve this, i have an script component in data flow, to check whether the input data is coming as null. I have added the output column of boolean type to the script component, it will be assigned to TRUE when there is null for the Not Null column in the script.
And in the follwing conditional split, i am checking the flag for TRUE to reject the record.
Is there any other way to handle this validation?
Regards

I have a excel sheet with some data and blank columns. I have a ssis package using to import data from excel to sql table. For blank excel columns it is importing as null instead i want to show them as '0'. If data comes in it should update the data.

I need a query to list the tables in SQL sever with respective database they belong across databases.
I can obtain list of tables from Sys.Tables / Sys.Objects Views but how do I correlate to which DB a table belongs to?
The Sys.Databases View list the databases with their respective Ids. But, the DBID is not part of Sys.Tables / Sys.Objects Views.
Which View will allow me to fetch database to table mappings?

View 3 Replies View RelatedHi,
my configuration file provides parameters that are used for an SQL query in my package. However, for these parameters it must be possible to pass NULL to the query.
This seems to be impossible in SSIS..? If the config file provides no value, the package uses a default value - and this default value can not be null.
Any suggestions?
Thanks a lot,

Hi everyone,
On daily basis I need to generate excerpts by mean of Excel. Prior to sql25k I used to play with Enterprise Manager and pick up the name of all the columns for a table very easily doing this
select top 1 f1,f2,-.. from table
name age
enric 80
How do I such thing from Sql Management Studio??
It's a silly thing, I know, but it's very useful for me because when I've got those columns then I can do paste them perfectly into .XLS.
Otherwise I see forced to write one by one and sometimes tables have more than 60 columns
It's not useful generate a CREATE TABLE script or launch SP_HELP <MYTABLE> because I obtain the name of the columns in vertical no horizontal.
Thanks a lot!!!
Hello all. I need to extract the column names that form the primary key group on a table in SQL Server. I have a table called Account and it contains ten columns. The primary key consists of two columns - MasterAccountID, AccountID. This primary key is a unique constraint and is clustered (it acts as an index as well as a primary key group). I have tried the following to no avail:exec sp_pkeys Account -> returns no rowsexec sp_helpindex Account -> throws an error stating that the object 'Account' does not existIf I run the following SQL statement, I can see all of the PK_* constraints in the database, so I know they are there:select * from information_schema.table_constraintswhere constraInt_type IN ('PRIMARY KEY','FOREIGN KEY') Again, I need to be able to specify a table name and have it return the columns (don't care if it returns extra fields) that make up the primary key fields for that table. Thanks!

I just want to query all records with the maximum value in column invoices.numbers. So for instance I have records with invoice numbers = 850, 849, 800 respectively. I want only records 850 (the highest value). Then next month I want invoices with value 851. Anyone know how to write this easily so I don't have to write it out everytime, e.g. invoice.numbers=851?

I have two tables that have no relation. However, both have a column which has a field of nvarchar(50) that I want to retrieve together in one operation and bind to a DropDownList in a sorted fashion. So, what I'm trying to achieve is this:
1. SELECT name FROM table1
2. SELECT name FROM table2
3. Join the two results together and order them alphabetically
4. Return the result set
I'm not sure how to do this or even if it's possible. Ideally I'm hoping it can be done in a stored proc.
Hi,
SQL Server 2005 has a new very useful feature for creating non-clustered indexes called INCLUDE <columns> which are very helpful when trying to create covering indexes.
Does anyone know of a way to retrieve these INCLUDE columns through any of the system metadata tables? The sp_helpIndex stored procedure is what I currently use but that only returns the (sorted) index columns and not the include columns.
Thanks in advance,

I am using Query Writer (should be SQL 2005) and have included the following code.
The end result: -should retrieve columns and display the count for two different data sources that were added by personnel in a specific department.
Problem: results are returned but not accurate. The code below works just fine and returns the results for all spot buy orders added by personnel in the sales department. However, I want to add a column in the same report that also counts blanket orders from the exact same table added by personnel in the sales department. The database uses views (v) in lieu of dbo.
Parameters:
@Add_Date_From SMALLDATETIME='',
@Add_Date_To SMALLDATETIME='',
@Last_name VARCHAR(50)='',
@First_Name VARCHAR(50)=''
Query:
SELECT
T1.Last_name,
T1.First_name,
T2.Position,
T3.Add_date,
COUNT(T4.PO_Type) AS 'Spot Buy Added'
[Code] ....
If I substitute COUNT(T4.PO_Type) AS 'Spot Buy Added' with COUNT(T4.PO_Type) AS 'Blanket Added' I also get accurate results for the blanket order. IE separately they work just fine. If I try to combine the two that is where the trouble begins.
What am I doing incorrectly when I try to add the criteria/code for the additional column to count the blanket orders?
I have a table imported from excel(5 var fix and 5 val fix) like:
Var1 val1 var2 val2 var3 val3 var4 val4 var5 val5
Color Red Size 4 Height 2inch NULL NULL NULL NULL
Color Red Size 5 Height 2inch NULL NULL Length 1 cm
Color Red Size 4 Height 3inch NULL NULL NULL
Color Black Size 6 Height 1inch NULL NULL NULL NULL
I need the output as
Var --- Val
Color --- Red,Black
Size --- 4,5,6
Height 1inch,2inch,3inch
Length 1 cm
Var or val can be either NULL or white space. I cannot use a function.
I have
Customer table, tblCust: ID; Name
1 Peter2 Mary
Product table, tblProduct: ID; Name
1 Banana2 Orange3 Apple
Order tblOrder, tblOrder: CustID; ProductID; Amount
1 ;2 ;$20 – means Peter ordered $20 oranges
How do I write the SQL query so that the values in tblProduct become column, currently I have 20 items in that table. So, it will return something like this according to the information that I provide above?
Name Banana Orange Apple
Peter 0 20 0
Till recently we were using the following code to retreive schema information of columns of tables
Dim schemaTable = connection.GetOleDbSchemaTable( _
System.Data.OleDb.OleDbSchemaGuid.Columns, _
New Object() {Nothing, Nothing, tableName, Nothing})
Now instead of getting the name of table (which i was using as param for filtering) i'm going to receive a sql-query. Now my question is if I were to get a query like the following :
SELECT
[EmployeeID],
[Title] + ' ' + [LastName] + ' ' + [FirstName] AS FullName,
[BirthDate],
[Address],
[City] + ', ' + [Region] + ', ' + [Country] + ' - ' + [PostalCode] AS FullAddress
FROM [dbo].[Employees]
Then how can I retrieve the schema information of only the columns present in the query.
(Its possible that i might get a query with multiple tables with joints)...
So I have been trying to get mySQL query to work for a large database that I have. I have (lets say) two tables Table_One and Table_Two. Table_One has three columns: Type, Animal and TestID and Table_Two has 2 columns Test_Name and Test_ID. Example with values is below:
**TABLE_ONE**
Type Animal TestID
-----------------------------------------
Mammal Goat 1
Fish Cod 1
Bird Chicken 1
Reptile Snake 1
Bird Crow 2
Mammal Cow 2
Bird Ostrich 3
**Table_Two**
Test_name TestID
-------------------------
Test_1 1
Test_1 1
Test_1 1
Test_1 1
Test_2 2
Test_2 2
Test_3 3
In Table_One all types come under one column and the values of all Types (Mammal, Fish, Bird, Reptile) come under another column (Animals). Table_One and Two can be linked by Test_ID
I am trying to create a table such as shown below:
Test_Name Bird Reptile Mammal Fish
-----------------------------------------------------------------
Test_1 Chicken Snake Goat Cod
Test_2 Crow Cow
Test_3 Ostrich
This should be my final table. The approach I am currently using is to make multiple instances of Table_One and using joins to form this final table. So the column Bird, Reptile, Mammal and Fish all come from a different copy of Table_one.
For e.g
Select
Test_Name AS 'Test_Name',
Table_Bird.Animal AS 'Birds',
Table_Mammal.Animal AS 'Mammal',
Table_Reptile.Animal AS 'Reptile,
Table_Fish.Animal AS 'Fish'
From Table_One
[Code] .....
The problem with this query is it only works when all entries for Birds, Mammals, Reptiles and Fish have some value. If one field is empty as for Test_Two or Test_Three, it doesn't return that record. I used Or instead of And in the WHERE clause but that didn't work as well.

I'd like to know how to do a SELECT Query using the following tables:

(some date)Toyota/50/3
(some date)Ford/30/3
Miles Type Table
MilesTypeID/MilesType
=================
1/City
2/Highway
3/Off-Road

Date/Car/City Miles/Highway Miles/Off-Road Miles
=====================================
(date)-Ford-20-0-0
(date)-Chevy-0-20-0
(date)-Ford-20-0-0
(date)-Toyota-0-0-50
