Hi... I'm reading the MS Press 70-442 Self-Paced Training kit, and I'm having problems with this example.
I'd like help getting it to work correctly, or understand why it is isn't working the way I planned.
On page 67, the lab is about the APPLY operator (CROSS APPLY and OUTER APPLY). I first have to input a sample table-valued function into the AdventureWorks database:
Code Block
CREATE FUNCTION fnGetAvgCost(@ProdID int)
RETURNS @RetTable TABLE (AvgCost money)
AS
BEGIN
WITH Product(stdcost)
AS
(
SELECT avg(standardcost) as AvgCost
FROM Production.ProductCostHistory
WHERE ProductID = @ProdID
)
INSERT INTO @RetTable
SELECT * FROM Product
RETURN
END
and then run a sample T-SQL statement
Code Block
SELECT p.Name, p.ProductNumber,
Convert(varchar, cost.AvgCost,1) AS 'Average Cost'
FROM Production.Product p
CROSS APPLY fnGetAvgCost(p.ProductID) AS cost
WHERE cost.AvgCost IS NOT NULL
ORDER BY cost.AvgCost desc
My problem is with the WHERE clause... According to page 56, CROSS APPLY returns only rows from the outer table that produces a result set, so why do I need to explicitly filter NULL values?
When I remove the WHERE clause, the query retrieves lots of NULL AvgCost values.
Again, according to page 56, it is the OUTER APPLY that returns all rows that return a result set and will include NULL values in the columns that are returned from the table-valued function.
So, in short, I don't see the difference between CROSS APPLY and OUTER APPLY, using this example, when I remove the WHERE clause?
(Please refrain from introducing another example into this question.)
I am using CROSS APPLY instead of UNPIVOT to unpivot > one column. I am wondering if I can dynamically replace column names based on different tables? The example code that I have working is based on the "Allergy" table. I have thirty more specialty tables to go. I'll show the working code first, then an example of another table's columns to show differences:
select [uplift specialty], [member po],[practice unit name], [final nomination status]
,[final uplift status], [final rank], [final uplift percentage]
,practiceID=row_number() over (partition by [practice unit name] order by Metricname)
,metricname,Metricvalue, metricpercentilerank
[code]....
Rheumatology Table:The columns that vary start with "GDR" and [GDR Percentile Rank] so I'm just showing those:
GDR (nvarchar(255), null)
GDR Percentile Rank (nvarchar(255), null)
GDR PGS (nvarchar(255), null)
GDR Rank Number (nvarchar(255), null)
PMPM (nvarchar(255), null)
[Code] ....
These are imported from an Excel Workbook so that's why all the columns with spaces for now.
I have a table called test with 4 fields namley studentname, Mark1, Mark2, total (formula column).
Created table test in the following structure,
create table test (studentname varchar(50), Mark1 numeric, Mark2 numeric, total as ([Mark1]+[Mark2]))
Now I need to drop formula nature of this column total and assign default value '0'. I like to know how to do it using T-Sql script.
Thanks for your help in advance.
when creating a new table. How can I set the default value of the column to equal the value of another column in the same table?
View 5 Replies View RelatedWell here's one of those excruciatingly simple obstacles:
In SQL Server 2005 (Mgmt Studio): according to BOL, the syntax to set a default value for an existing column is:
ALTER TABLE MyCustomers ALTER COLUMN CompanyName SET DEFAULT 'A. Datum Corporation'
However, when I Check:
alter table CommissionPayment alter column Amount Set Default 0
I get the error message:
"Incorrect syntax near the keyword 'Set'."
No other combinations of this syntax work.
Help! What am I missing?
I have a UDF that returns a char(10) random value. This runs fine when calling it directly via Query Analyzer, Stored Procs, etc.
I now want to create a new column in a table (via the Table Designer) and want to set the default value to the function. I have entered dbo.f_myfunction() for "Default Value", but I get an error:
Unable to modify table.
ODBC error: [Microsoft][ODBC SQL Server Driver][SQL Server]Could not create constraint. See previous errors.
[Microsoft][ODBC SQL Server Driver][SQL Server]SqlDumpExceptionHandler: Process 51 generated fatal exception c0000005 EXCEPTION_ACCESS_VIOLATION. SQL Server is terminating this process.
The function is in the same database as the table. This is all on my local database where I am the admin.
I have also tried database.dbo.f_myfunction(), but I get an Invalid Object error.
Any help would be appreciated. Thank you,

Hi
I have a table with the list of employee and 15 column with data type float or money , that represent the number of hours, airfare,gas,parking food, etc....
I have 2 choice:
-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
hi, i was wondering how to set default value in the datetime column of the database so that it will enter current date and time if one is not provided when a row is populated. is there a store procedure to do this? or built-in function?

I would like to have the date value 1/1/2499 entered as the default value in a date field if no value is specified. I have added 1/1/2499 as the default value for the column however when I insert a record into the table the date 1/1/1900 is entered even though I haven't specified a date. Any way to accomplish this? Thanks.

I've done some research on setting the default value of a column and found the following code:
ALTER TABLE [table1] ALTER COLUMN [column1] SET DEFAULT 0
I am trying to set column1 within table1 to a default value of 0, column1 is an int data type. But it doesn't work within MS SQL SERVER 2000.
Can anyone tell me what's wrong?
HI All,

I did this...
ALTER TABLE tm_spn_equip_def ADD Customer_No int NOT NULL DEFAULT dbo.f_spn_GetCustomerNo() WITH VALUES
Now when I attempt to do this...
ALTER TABLE tm_spn_equip_def DROP COLUMN Customer_No
I get an error:
Msg 5074, Level 16, State 1, Line 1
The object 'DF__tm_spn_eq__Custo__019E3B86' is dependent on column 'Customer_No'.
Msg 4922, Level 16, State 9, Line 1
ALTER TABLE DROP COLUMN Customer_No failed because one or more objects access this column.
How can I get around this?
TIA!
If no value is supplied on an insert for an int column that allows nulls, will the value be null or 0 ?

View 6 Replies View RelatedI have a char(11) for SSN, and I would like to default it to123-45-6789 so I can avoid having nulls in this column, and so I caneasily find the rows in which I need to have a 'correct' SSNentered/updated.I tried using just 123-45-6789, and SQL2005 doesn't seem to bedefaulting to this value, it seems to be keeping it as(((123)-(45))-(6789), and not placing it into this column when a newrow is created....Is there some special way I must specify defaults for a char(11) field(Yes, I will include the dashes).Thank you,Tom
View 7 Replies View RelatedI know that the correct syntax to set the default on a column in SQL Server 2005 is:
Alter Table <TableName> Add Constraint <ConstraintName> Default <DefaultValue> For <ColumnName>
But from what I can gather, the SQL-92 syntax is:
Alter Table <TableName> Alter Column <ColumnName> Set Default <DefaultValue>
This generates an error on SQL Server 2005.
Am I wrong about the standard syntax for this statement? If this is the standard, why doesn't SQL Server 2005 support it? I am trying to avoid code that will only work on certain database managers.
Thanks.
Hello all,
I have a table with a column:
ThruDate datetime not null
I have a function call set up as default for the col
([dbo].[fn_DateHigh_Get1]())
I have a stored procedure that inserts into the table - it expects @ThruDate as a parm. I default the parm to NULL -
When the sp executes its insert stmt i get error 515 (null cannot be inserted....).
When i just enter the row manually in enterprise manger (and just tab through the ThruDate col) all is well - ThruDate gets the default as calculated by function [dbo].[fn_DateHigh_Get1]()
Why does the sp fail - i.e. why isn't the default applied?
thanks
Is it possible to use a stored procedure to fill the default value of a column when i'm building the db? i mean if i can use a stored procedure for the "colum property": "default value or bnding" if yes how can i do it?

I can't seem to get the syntax correct for ALTERing an existing column with a default constraint. I've been to Help and BOL. There are examples that show how to use the ALTER command to add a column with a default constraint but not how to do it on an existing column.
Any help would be appreciated.

Hi,
How do I design a table column named UpdateDate that will give the default date and time upon inserting a record into the table
I'm using Enterprise Manager in MSSQL
Many Thanks
I want to set a default value to a column while adding it.
Create table test(id int )
insert into Test values(123)
alter table test add column2 int default(0)
In the above query I have set the default value, but it will not set the default value to the already inserted columns.
So how to set a default value for the already inserted rows, while adding a new column to it ?
From standard SELECT need to display specific column values normally, together with any NULLs in the same column not as NULL. My below effort parses however does not change to <new_value>.

FROM [tbl]
