Where is SQL storing and caching the assemblies used by CLR SP?
I want to read a mapped configuration file for that assembly but it seems that assemblies are not read form their initial location.
Is there a way to use configuration files for the assemblies used by CLR SPs? (I don't want to use a static string to point to a file on the disk)
I've developed and tested an application that utilizes the standard (.SQLEXPRESS, not user instance) instance of SQL Server 2005 Express. I'd like to be able to say that my solution will operate on any of the 32-bit SQL Server editions (Express, Workgroup, Standard, Developer, Enterprise).
I've found anecdotal comments from people saying that SQL Express is a subset of the other versions. However, in order to truly validate my "any edition" claim, I need to either:
a) Install and test my solution with all editions of SQL Server, or
b) Provide a justification for saying: "If it works on SQL Express, it'll work with the other editions".
Does anyone know if there is some official documentation somewhere that affirms the functional equivalence of the editions?
Is there documentation that states that each SQL Server edition is compiled from the same codebase?
Thanks for any help

Dear all,

-------- -----
1 spoon
2 phone

Select
id_Guest,
case orderName
when '' then Null -- Sql server gives error in thsi case
end as orderName
from v_GuestOrder
So I need to assign NULL to OrderName is query return empty string,
it will be treated by Crystal reports as Null
Please help , thanks
I have a SQL Server table with nvarchar type column which has not null constraint. I am inserting empty string ("") from Java to the table column. When I export this table into .csv file using bcp tool, empty string gets written as NUL character. Is there any way I can bcp out empty string as empty string itself instead of NUL to the file?

View 4 Replies View RelatedI want to replace a column value with a null if the string is empty. I would have thought this simple expression would do it:
RTRIM([FromContractSymbol]) == "" ? NULL(DT_STR, 0, 1252) : (DT_STR, 6, 1252)FromContractSymbol
Yet, I get the following error:
For operands of the conditional operator, the data type DT_STR is supported only for input columns and cast operators. The expression "...see above..." has a DT_STR operand that is not an input column or the result of a cast, and cannot be used with the conditional operation.
The expression works if I replace the NULL(DT_STR, 0, 1252) with say "A" and the expression works on other non-string columns. (As in "NULL(DT_I1) : (DT_I1)100")
I need to check in my Stored procedure if the information passed is null or empty so I can decided to insert the new value or keep the old. How do I accomplish this please in T-SQL. Thanks in advance.

Trying to insert null value into sql table, but not working, if I use:
if (strMyText.Length == 0) command.Parameters.Add("@Text", DBNull.Value); // or using:("@Text", null), or using:("@Text", DBNull) else command.Parameters.AddWithValue("@Text", strMyText);
When I go back to table, I see the value is: 'NULL', has single quotation mark, suppose to be: NULL
Where is the problem?

Hi all, I have some columns in my database which allows null. I want to know if leaving the field to be NULL or storing an empty string into the field, which will take up more space?? if the field type is varchar(100)
View 5 Replies View RelatedHi folks,
I've have about 100 tables, for some reasons, column values that are originally NULL was inserted as emtpy string. So, I am wondering if I can write JUST ONE SQL (hopefully don't have to specify the field names in the SQL as well) for each table so that all the empty strings will be converted back to NULL.
THANKS JOHN
In the Column Properties window's 'Default Value or Binding' property, how do you specify an empty string?
Thanks.

Can we have blank value in Primary key field? Two fields are chosen as Primary Key for this table but the issue is at any given time one value will be blank when other is populated. Does sql server still order the records based on these keys? (Clustered index). Or should I just go about adding ID (identity)?

View 4 Replies View RelatedHello,
I have a problem where I need to include data from a table where one of the joined columns can contain empty strings. The emptry string column and its related columns need to be included in the results of the query.
The Join looks like this:
SalesData.dbo.tbl_CYProcessedSales ps
INNER JOIN SalesData.dbo.vw_Product_CYProcessedSalesXref xr
ON ps.Prod = xr.Prod
AND ps.Acct = xr.AcctCode
INNER JOIN TxnRptg.dbo.vw_NetNewRevenueUnion nn
ON xr.BillingType = nn.BillingType
AND xr.ProdGroup = nn.Product
AND xr.AcctCode = nn.AcctCode
The problem occurs on the xr.BillingType = nn.BillingType portion of the join. the nn.BillingType can contain empty strings. I've tried a LEFT join to vw_NetNewRevenueUnion, but this has not worked.
In vw_NetNewRevenueUnion, BillingType becomes an empty string within a CASE statement if BillingType is NULL. I've thought about using something like 'All' in the ELSE condition, and doing the same in the vw_Product_CYProcessedSales view just so I don't have to deal with an empty string.
If I were not to do that, is there some way I can handle the empty string issue within the join so that empty string records will be included in the query results?
Thank you for your help!

I am using a SQLDataSource with the following Select query. If the "spouse" values are not in the database, I get the HTML non-breaking-space character back, rather than an empty string.
SelectCommand="select applicant_id, (applicant_last_name + ', ' + applicant_first_name) as applicant_name, CONVERT(varchar(10), applicant_dob, 101) as applicant_dob, applicant_ssn, (spouse_last + ', ' + spouse_first) as spouse_name, CONVERT(varchar(10), spouse_dob, 101) as spouse_dob, spouse_ssn from applicant where applicant_last_name like '%'+@last_name+'%' order by applicant_last_name"
Here is the relevant code-behind:
TextBox tb = (TextBox)formView.FindControl("SpouseName");
tb.Text = e.Item.Cells[4].Text;
DatePicker dp = (DatePicker)formView.FindControl("SpouseDateOfBirth");
if (e.Item.Cells[5].Text.Length > 0)
{
try // this is a try/catch because nbsp is not parsed as a date
{
dp.DateValue = DateTime.Parse(e.Item.Cells[5].Text);
}
catch
{
dp.txtDate.Text = "";
}
}
tb = (TextBox)formView.FindControl("SpouseSocialSecurityNumber");
tb.Text = e.Item.Cells.Text;
Thoughts?

OrderID = 1 Color='Black' ColorKey=4

This seems to be a rather old problem (http://www.themssforum.com/SQLServer/Does-empty/) but I couldn't find an answer yet.
The problem is: I have two tables t1 and t2 where t1 is a staging area of t2.
t1: (id int not null, phone varchar(30))
t2: (id int not null, phone varchar(30))
Data in t1: (1, '') <- empty string
Data in t2: (1, ' ') <- a blank
Comparing t1.phone with t2.phone results in equality which in my opinion isn't correct.
The question ist: How can I change the behaviour of SQL-Server to result in inequality so that the change in my staging table is detected correctly?
Thanks in advance

In sql server 2000 - our QA pointed out that his testing for empty strings returned 200 + rows but that when he clicked in the field there were obviously a space there. This issue came up because of the script I created to replace and earlier one that queried on empty strings instead of datalength and the earlier script always reported that it had updated x number of rows regardless of how many times it was run on the same database.
QA query based on the earlier script:
Select * from StringTable
WHERE (LongString = '' OR LongString IS NULL)
My script:
The fields are nvarchars in the newer database but older version of the database had varchars. I had created a script to replace empty strings as follows:
-- if LongString column is varchar - run varchar update else nvarchar update
If exists (Select * from sysobjects o
inner join syscolumns c on c.id = o.id
where c.name = 'LongString' and o.name = 'StringTable' and c.xtype = 167) begin
-- update varchar LongString
UPDATE StringTable
SET LongString = char(32)
-- Select * from StringTable
WHERE ((DATALENGTH(LongString ) < 1) OR LongString IS NULL)
END
Else Begin
-- update nvarchar LongString
UPDATE StringTable
SET LongString = char(32)
-- Select * from StringTable
WHERE ((DATALENGTH(LongString ) < 2) OR LongString IS NULL)
END
If exists (Select * from sysobjects o
inner join syscolumns c on c.id = o.id
where c.name = 'ShortString' and o.name = 'StringTable' and c.xtype = 167) begin
UPDATE StringTable
SET ShortString= char(32)
-- Select * from StringTable
WHERE ((DATALENGTH(ShortString) < 1) OR ShortString IS NULL)
END
Else Begin
-- update nvarchar ShortString
UPDATE StringTable
SET ShortString= char(32)
-- Select * from StringTable
WHERE ((DATALENGTH(ShortString) < 2) OR ShortString IS NULL)
END
My method for checking for datalength appears to work correctly why doesn't the QA script? I thought it might have to do with the nvarchar used in the table but I changed the column to a varchar and still has the same issue.
Thanks
