Implicit Conversion Of Datatype Text To Nvarchar Is Not Allowed.
Jul 20, 2005
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 no
lines of code get executed, and immediately after that the ROLLBACK
TRANSACTION occurs and the applications fails.
But to my surprise i am able to do the same thing on a different
machine using the same application and the same database on the same
server 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 come
up with a quick response.
Kind Regards,
Amit Kumar

Here is the situation...
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);
OleDbParameter[] myParams = {
ParamBuilder("@StarDate", OleDbType.DBDate, 8, _startdate),
ParamBuilder("@FinishDate", OleDbType.DBDate, 8, _finishdate)
};
ExecuteNonQuery("myInsert", myParams);
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
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*
Help!

Exception in one of the stored procs:
Conversion failed when converting the nvarchar value to datatype int. After moving database from 2000 to 2005.
Using backup and restore.
Note I had the same issue after restoring the production database on my local server SQL2000->SQL2000.
The problem was solved by restoring master and msdb from the production. But I can't do this on the SQL2005.
This is not a collation issue as I have ensured collation is the same on all databases including the system ones.
The database in question makes extensive use of user defined data types (Which I have recreated on the destination server).
Can anyone please help?

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:

I 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?
Thanks,
Rut

I also tried, creating another column "DATE2-datatype:datetime" and updating the column with the old one.
UPDATE users SET DATE2 = DATE.. But it also faild,..
How can I modify the column?

Hi I get the following error:
Implicit conversion of varchar value to varchar cannot be done
because the collation of the value is unresoved due to a collation
conflict
SELECT

NameFull, -- Error here
-- Accounts_Users.NameFirst + ' ' + Accounts_Users.NameLast AS NameFull, -- This line works

NameFirst and NameLast are VarChar(30) and BusinessUnit VarChar(50), I
did try converting it to 30 also but still got the same error
The sp works on my dev sql server but not on the live one, I am using Management Console v2 (dev) and 1.2 (live server)

Good Afternoon
Hope that somone can shed some light...
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:
INSERT INTO CALICOTOTESTAS400.S105Z1NM.ORDTALIB.itmrva0# (TRID30, ITNO30, ITDS30, ITYP30, INVF30, UMST30, ITAC30, UUCA30, EGNO30, RTID30)
VALUES (@v_action, @v_modelNumber, @v_modelDesc, '1', 1, 'EA', @v_acctClass, @v_modelyear, @v_engRevision, @v_spectype)
However, when I try to close the S/P window I get the error:
Error 257: Implicit conversion from data type varchar to binary is not allowed. Use the CONVERT function to run this query.
So, I changed the insert statement to this:
INSERT INTO CALICOTOTESTAS400.S105Z1NM.ORDTALIB.itmrva0# (TRID30, ITNO30, ITDS30, ITYP30, INVF30, UMST30, ITAC30, UUCA30, EGNO30, RTID30)
VALUES (CONVERT(binary, @v_action), CONVERT(binary, @v_modelNumber), CONVERT(binary, @v_modelDesc), CONVERT(binary, '1'), 1, CONVERT(binary, 'EA'), CONVERT(binary, @v_acctClass), CONVERT(binary, @v_modelyear), CONVERT(binary, @v_engRevision), CONVERT(binary,
@v_spectype))
Now the S/P closes without the error. But when I send it to the AS400 I get unrecognizable characters in the fields.
Then I started thinking...I am not trying to do anything with binary fields.
So I am really lost. Please help.
Thanks,
Ed 330-273-7521

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.

Good afternoon,
I have an issue with an ssis variable datatype.
The scenario is as follows:
I have a stored procedure:
PROCEDURE [dbo].[sp_newTransaction]
@sourceSystem varchar(50),
@txOut NUMERIC(18,0) OUTPUT
AS
insert into scn_transaction (sourceSystemName) values(@sourceSystem);
SELECT @txOut = @@identity
Whose purpose is to perform an insert into a table and return me the identity value of the inserted record, which I'll then use throughout the rest of my package. The identity column in the inserted table is numeric(18,0).
I execute the stored proc with the following sql with an OLE DB connection manager:
exec sp_newTransaction ?, ?
The first parameter is a string variable from earlier in the package, and the second is the output parameter. I have the following parameter mappings to the execute sql task:
User:ystxId output numeric 1 -1
User:ourceSys input varchar 0 -1
The proc is correctly called, and the row insesrted, however I get a type conversion error when SSIS attempts to map the return parameter to my package variable... I've tried all sorts of combonations, and can't seem to get it to execute.
At one point I wasn't returning a numeric, but rather an int from the stored proc, and all was well until I went to use the variable in a derived column later in the package, and the type was converted quite incorrectly (a 1 was 77799789080 or some such), indicating a type conversion error likely related to the encoding of the number.
I'd like to keep the datatypes as numeric and make ssis use those - any pointers are greatly appreciated as to what type my package variable should be to allow proper assignment of a sql server numeric type to it.
Thanks much,
B

I can't seem to get nvarchar(max) to work with ADO 2.8 using sql native client.
I am creating a stored procedure and every time i attempt to add a parameter to the command object of type nVarChar(max) I receive the error
"Parameter object is improperly defined"
here is the code to add the parameter
cmd.Parameters.Append cmd.createparameter(@piComments,adLongVarWChar,adparaminput,,me.comments)
adLongVarWChar is the ado data type i am using to map to the new nVarChar(max) but it does not appear to be working.
Is this supported in ADO? I am using the sql native client connection to connect to the database as follows.
pubStrConnectionString = "Provider=SQLNCLI;" _
& "Server=.sqlExpress;" _
& "Database=MyDBName;" _
& "Integrated Security=SSPI;" _
& "DataTypeCompatibility=80;" _
& "MARS Connection=True;"

Hi, I have created a database using VWD to keep values of urls and have structured it as...
Prefix (http://, network name), address(www.name.com), and name (name of address), the address field has been defined as a nvarchar(MAX).
Most of the addresses updated into the address field work, except something like: www.java-scripts.net/javascripts/Image-Rollover-Script.phtml.
I get this error:
Cannot open user default database. Login failed.Login failed for user 'NETWORKNAMEASPNET'.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Line 1179: }
Line 1180: try {
I can insert something like www.google.com into the addresses field without any errors. Any ideas why?If it is a nvarchar type it should be able to except all sorts of characters??

We have few stored procedures that use nvarchar datatype, this was not issue on SQL server 7.0 but in 2000 becomes a big issue.
For example query that runs for 3 minutes in SQL server 2000 by replacing NVARCHAR to VARCHAR the same query runs for 2 seconds.
The biggest challenge that I have deals with tables and user-defined datatypes of NVARCHAR that has been bounded to the table.
How can I alter those without data corruption?

The transaction_date is datetime and date1 is nvarchar.
When I run the script:
Insert into payment(transaction_date)
Select convert (datetime, date1) from dep01
I get the following message:
Server: Msg 8115, Level 16, State 2, Line 1
Arithmetic overflow error converting expression to data type datetime.
The statement has been terminated.
Thanks in advance, Mike

Hi,
Can someone please explain to me how the datapages in Microsoft SQL Server 2000 works. The pages are supposed to be 8K, that is 8192 bytes of which only 8060 are accessible for data storage (due to overhead).
Now, I currently have a table containing 8 fields. Two of these fields are varchar and should be converted to nvarchar. One of the varchar fields is limited to 255 characters and the other to 4000 characters. When I convert the 255 characters field to nvarchar it works just fine, but when I want to convert the 4000 characters field I get an error from MS SQL saying that it gets to big. Is the error only for the 4000 characters field (which growths to 8000 bytes when using nvarchar instead of varchar) or must the whole table fit into one datapage?
Could a blob maybe solve my problem, or will I face new problems when storing unicode characters in a blob?
Thanks in advance

One of my clients decided to put letters into their customers' account numbers. They have a numbering scheme where all temporary accounts have a letter in the account OR are numbered greater than 33000, and all permanent accounts are all digits and less than or equal to 33000. all primary accounts have a NumberSuffix of 000.
Now i am tasked with retrieving all primary, non-temp accounts. I cannot simply do WHERE Number <= 33000 because when it gets to an account containing a letter like "00A01", it craps out and says "Conversion failed when converting the nvarchar value '00A01' to data type int."
So decided to run a filtering query first to filter out all accounts with letters, and then from that dataset select all accounts <=33000.
WITH members (FirstName, LastName, Number, NumberSuffix) AS
(
SELECT
dbo.Entity.FirstName,
dbo.Entity.LastName,
dbo.Entity.Number,
dbo.Entity.NumberSuffix
FROM
dbo.Entity
WHERE
NumberSuffix = 000 AND
Number NOT LIKE '%A%' AND
Number NOT LIKE '%B%' AND
Number NOT LIKE '%C%' AND
Number NOT LIKE '%D%' AND
Number NOT LIKE '%E%' AND
Number NOT LIKE '%F%' AND
Number NOT LIKE '%G%' AND
Number NOT LIKE '%H%' AND
Number NOT LIKE '%I%' AND
Number NOT LIKE '%J%'
)
SELECT *
FROM
members
WHERE
Number <= 33000
ORDER BY
Number
when i do this, i get the same error for some reason. Yet when i execute this at the end instead:
SELECT *
FROM
members
WHERE
Number LIKE '%A%'
ORDER BY
Number
i get an empty set (meaning it actually does get filtered).
but somehow it still able to participate in a range comparison?
WHY??
thanks,
Leon
