have a sql statement that must run in both sql server and oracle. I can't change the sql statement as it is created as part of a core application from Rational Rose.
Basically the problem is that I have a table with a column defined as a decimal type in sql server (numeric in oracle).
The select statement, however, treats the column as a char. I can reproduce the problem with this simple code:
create table atest2 (a decimal(9,0))
insert into atest2 values (1)
insert into atest2 values (2)
insert into atest2 values (null)
insert into atest2 values (4)
select * from atest2 where a = ' '
This gives the error:
Error converting data type varchar to numeric.
The documents seem to indicate the sql server will implicitly convert decimals to varchar but this doesn't seem to be happening. Is there an environment setting that might control this?

In a stored procedure, the following code is causing a huge read and CPU load when it really shouldn't. The @IDParameter below is coming in as a parameter to the proc.
Here's the snippet of code where the problem is coming in:
DECLARE @ID INT; SET @ID = (SELECT ID From OtherTable WHERE FKID = @IDParameter); SELECT COUNT(*) FROM LargeTable
WHERE MostlyZeroID = @ID AND MostlyZeroID > 0Most (90+%) of the MostlyZeroID rows are 0 (hence the name) but regardless of distribution this should evaluate with minimal work on SQL Server's part to 0. However, when this was run, it is using a ton of CPU and doing a ton of Reads as it seeks through the entire index. When I look at the execution plan, I see under the seek predicate a Scalar Operator(CONVERT_IMPLICIT(int,[@1],0)) which is what is destroying the performance.
I've confirmed that the MostlyZeroID column in the LargeTable is defined as an INT NOT NULL. I also tested the scenario outside the stored procedure without any variables as the following to make sure it wasn't some kind of strange parameter sniffing scenario:
SELECT COUNT(*) FROM LargeTable WHERE MostlyZeroID = 0 AND MostlyZeroID > 0
However, this query also did the implicit conversion. I then tried this out on a temp table populated with a similar number of records (100 million) with a similar distribution and I didn't get the implicit conversion (I got a constant scan as I would've expected) when I did this:
SELECT COUNT(*) FROM #TestTable WHERE MostlyZero = 0 AND MostlyZero > 0
I also tried the same on several other tables that are set up similarly (large amount of zeros in an INT column) and I always got a constant scan and didn't do an implicit conversion.
why the query engine is interpreting this 0 as something other than an INT and doing an implicit conversion when getting the count in the scenario above? What can be done to protect against it? In the above scenario, an IF @ID > 0 statement was placed before the code including the count since there was no reason to even run the code if the @ID was equal to zero.
I am trying to construct a query in Query Analyzer (with SQL Server 2000), but am getting an error regarding "implicit conversion."
Here is the query:
SELECT dbo.AUCTION.EbayNum, dbo.AUCTION.EndDate, DATENAME([month], dbo.AUCTION.EndDate) + ' ' + DATENAME([year], dbo.AUCTION.EndDate) AS [PmtMonth], dbo.LOT.Description, dbo.AUCTION.WinBid, PaidStat = CASE dbo.AUCTION.PaidStatus WHEN 0 THEN '' ELSE 'PAID' END, PaidAmt = CASE dbo.AUCTION.PaidStatus WHEN 0 THEN '' ELSE dbo.AUCTION.WinBid END FROM dbo.AUCTION INNER JOIN dbo.LOT ON dbo.AUCTION.LotNum = dbo.LOT.LotNum WHERE (LEN(dbo.AUCTION.Winner) > 0)
The error occurs in the PaidAmt CASE statment: "Implicit conversion from data type varchar to money is not allowed. Use the CONVERT function to run this query."
Why is there an implicit conversion going on? And how can I fix it? :mad:
Hi, I'm using this code to export record from sql to excel and i got this error message "Implicit conversion from data type text to nvarchar is not allowed. use the convert function to run this query"

I am using the HitSoftware driver to pass data to an AS400 from a SQL 7 database. Data makes it fine to 2 of the 4 tables but I cannot get the syntax correct to even get out of the S/P edtitor in SQL for the other 2.
I have fields in the SQL S/P defined as VARCHAR. The target fields on the AS400 are ALPHA. So I figured the insert statement to look like:
I am using SQL Server 2000. I have created a Store Procedure to insert information, 4 of the fields are date types. I am using OleDb Data Provider (System.Data.OleDb) namespace.
The dates are filled by a form (web form) on submit event, I created a class that has functions to create my OleDb Parameters. I add the parameters to the command and execute it through a SQL Server Stored Procedure. In the event that I must have coded something wrong, I tested in the SQL Query Analyzer and the IN parameters for the date I used the getDate() method. This is where I know it is OleDb and SQL Server Parameters.
What Converstion Format should I use in the SP for the date? OleDb.date are doubles from some date in 1979 or something or another. So I used an OleDbDataType.DBDate. It seems that when the Stored Procedure uses the IN Parameters dates provided by OleDbDataType.Date or DBDate, that it doesn't like the int format. I am guessing that I am not converting the date in the parameters in the Insert of the Store Procedure... this is basically what I have...
Function to add parameters and execute SP
private int _startdate = DateTime.Now; private int _finishdate = DateTime.Now.AddDays(30);
CREATE PROCEDURE myInsert @StartDate datetime, @FinishDate datetime AS
INSERT INTO myTable (STARTDATE, FINISHDATE) VALUES (Convert(datetime, @StartDate), Convert(datetime, @FinishDate))
Please keep in mind that I am using System.Data.OleDb namespace..... please don't tell me to use SQLClient, it seems since I've been so adaptive of using OleDb, that it sould work just as well. I am way too far into this to change my Provider to SQL Client, but I promise myself that the next project (if using SQL Server, I will be using SQLClient and I will keep using OleDb for Oracle.) *sigh*
I am facing a problem while using SQL Server with VB application.Implicit conversion from datatype text to nvarchar is not allowed.Use the convert function to run this query.When i see the trace file, i see one stored procedure called but nolines of code get executed, and immediately after that the ROLLBACKTRANSACTION occurs and the applications fails.But to my surprise i am able to do the same thing on a differentmachine using the same application and the same database on the sameserver with the same user id.Can anyone explain the reason of occurance of this problem.I require this very urgently, so i will be oblized if anyone can comeup with a quick response.Kind Regards,Amit Kumar

I know i can use the sentence SET IMPLICIT_TRANSACTIONS ON in a Stored Procedure to force SQL Server to set the connection into implicit transaction mode.
Have i a sentence or configuration to force all SQL Server connections to implicit transaction mode?
I'm investigating a poorly performing procedure that I have never seen before. The procedure sets the transaction isolation level, and I suspect it might be doing so incorrectly, but I can't be sure. I'm pasting a bastardized version of the proc below, with all the names changed and the SQL mucked up enough to get through the corporate web filters.
The transaction isolation level is set, but there is no explicit transaction. Am I right that there are two implicit transactions in this procedure and each of them uses snapshot isolation?
SET NOCOUNT ON; SET TRANSACTION ISOLATION LEVEL SNAPSHOT; DECLARE @l_some_type varchar(20), @some_type_code varchar(3), @error int, @error_msg varchar(50);
I have a report that has 3 nested lists. The report looks fine when I view it in the browser but when I print it or export it to another format it appears that keep together is on for each list because some pages are only partially filled. I do not have keep together turned on for any report control, and I don't have page break turned on for anything. This problem results in the report being many more pages than it needs to be. Can anyone help?
Hi Everyone- i have a report that include parameters that the user set and press the button ViewReport for rendering the report until that everything ok,.. .......but assume that there is an updating occurred on data after the user make the first press on the button ViewReport.
The problem is if the user press the button ViewReport again for the second time without changing the parameter value the report result will be the same even though it is the old data that appear in the 1st press button.
can anyone tell me how to handle this problem to make it refresh when the ViewReport button is pressed or if there is no solution can anyone provide me with a link that talks about that problem for more details
I am running into a problem which seems to indicate SQL Server 2005 is pretty aggressive with its implicit conversion which makes UNPIVOT apparently unusable for my current task of creating attribute/value pairs of strings for each of the records unpivoted around the primary key.
WITH cte as
(
SELECT 1 as Code, '2' as Status, 'Some Guy' as CreatedBy, Convert(varchar(19), getdate(), 120) as CreatedDate
)
SELECT
[Code]
,[Attribute]
,[Value]
FROM
cte
UNPIVOT([Attribute] FOR [Value] IN ([Status],[CreatedBy],[CreatedDate])) as U;
Msg 8167, Level 16, State 1, Line 1
The type of column "CreatedBy" conflicts with the type of other columns specified in the UNPIVOT list.
The same result shows up if I use an inner SELECT instead of the CTE:
SELECT
[Code]
,[Attribute]
,[Value]
FROM
(
SELECT 1 as Code, '2' as Status, 'Some Guy' as CreatedBy, Convert(varchar(19), getdate(), 120) as CreatedDate
) cte
UNPIVOT([Attribute] FOR [Value] IN ([Status],[CreatedBy],[CreatedDate])) as U;
It seems to me that some arbitrary decision about what column is processed first is made and the process fails as soon as a column is met which is not of the same datatype. I also think it is interesting that the engine will implicitly cast from varchar to DateTime but not the other way around.
If I execute multiple SqlCommands in a single .aspx, using a single SqlConnection, are all the commands part of the same transaction?
That is, if I say: cmd1.CommandText = "UPDATE foo SET myVal = myVal - 1" cmd2.CommandText = "SELECT myVal FROM foo"
cmd1.Connection = myConn cmd2.Connection = myConn
myConn.Open()
cmd1.ExecuteNonQuery() ' decrement myVal intResult = CInt(cmd2.ExecuteScalar()) ' select value of myVal
myConn.Close()
Do the UPDATE and the SELECT happen in the same transaction, or is it possible that someone else would have changed the value of myVal between these two calls?
Is there any difference between explicit inner join and implicitinner joinExample of an explicit inner join:SELECT *FROM employeeINNER JOIN departmentON employee.DepartmentID = department.DepartmentIDExample of an implicit inner join:SELECT *FROM employee, departmentWHERE employee.DepartmentID = department.DepartmentID
If i create a simple table with a foreign key constraint, does itcreate an implicit index on that given ID? I've been told this isdone in some databases, but i need to know for sure if SQL Server doesit. Has anyone heard of this before, on any other databses perhaps?Heres an example of how the foreign key constraint is being added:ALTER TABLE [dbo].[administrators] WITH CHECK ADD CONSTRAINT[FPSLUFSUOXZGAJOJ] FOREIGN KEY([AdministratorRoleID])REFERENCES [dbo].[administratorroles] ([AdministratorRoleID])My initial testing seems to indicate adding an index on the foreignkey column helps, but i need to know for sure. Any insight would begreatly appreciated!Bob

Hi does anybody know how to programmatically convert an SQL Server table into a dbf or an excel spreadsheet? I'm using C#. Also, i need to put the new table into a different folder. Thanks.
If I develop my app in SQL Server 2005 Express, and then want to use a hosting service that only offers full SQL Server 2005, do I have to do some kind of conversion to my DB file, and if so, what might that be? (I notice that there are hosting services that provide SQL Server Express...I'd like to know how much work it would be to be able to use other services.)
I am in the process of trying to create a mirror image of our Oracle database in SQL Server. I have all of the code that was used to create Stored Procedures on the Oracle side. I am having a lot of trouble trying to figure out what the corresponding syntax to create these procedures in SQL Server would be. Has anybody been able to locate any sources of information that would help me or had any experience with this problem? I would appreciate any help anyone can give me.
Specifically I am looking for help on the following items:
Oracle Sql Server RETURN NUMBER ? IS ? BEGIN ? SELECT FROM DUAL ? EXCEPTION HANDLING ?
Here's some of what I have so far: Oracle SQL Server CREATE OR REPLACE PROCEDURE CREATE PROC AS Variable_name @variable_name number numeric dual #temptable
I am converting a 6.5 database to 7.0. I have heard that some areas(for e.g. Nulls) are treated differently in SQL Server 7.0. So even if the conversion goes through smoothly there are poteential problems with the way Nulls are treated in 7.0. Is there any whitepaper or some other source which lists all the problems faced by developers when converting from 6.5 to 7.0?
