Hi,
I imported a table from Accees to SQL 7 with data in it.

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 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;"
thanks

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. Exception Details: System.Data.SqlClient.SqlException: Cannot open user default database. Login failed.Login failed for user 'NETWORKNAMEASPNET'.Source Error:

Line 1177: != System.Data.ConnectionState.Open)) {
Line 1178: this.Adapter.InsertCommand.Connection.Open();
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?

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?

Ok I have upgraded my works database from a poorly designed Access database to a SQL database. The previous system allowed NULL values and duplicates to be inserted into a field that should NOT ALLOW NULL Values or duplicates. Therefore, this issue has now been moved across to my new system as I cannot set these constraints on the field that has multiple NULL values.
My solution would be to use a sequential operator, so whatever = NULL would be changed to a sequential number that us as administrators would know was a bogus number starting at something like = 999999900 counting up from that. There are only 250 records that would require updating.
To make things more interesting this field is not a integer type, its a Nvarchar type as its a Hardware ID. Both numerical and characters are require.

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

How to sort table in sql2000 with ipaddress(format x.x.x.x) as column with nvarchar datatype in ascending order
without using stored procedure
Ex:
Table: netComputers(3 rows)
Column Name: ipAddress (string data type)
ipAddress
0.0.18.1
0.1.1.2
0.0.0.1
Sql query : if I use the query
Select ipAddress from netComputers order by cast( replace(ipaddress,'.','') as numeric(12)) asc
Gives result as :
ipAddress
0.0.0.1
0.1.1.2
0.0.18.1
Where as expected result should be:
ipAddress
0.0.0.1
0.0.18.1
0.1.1.2

Hi Everybody,
From the BOL, what I understood is, Text Datatype can accept more characters than 'char' & 'varchar' datatypes. There is no limitation like 8000 characters(what we hv in 'char' & 'varchar').
But I am surprised I am not able to add more than 8000 characters to my text datatype. Can anybody guide me how to do this?. Any help is appreciated.
tks in advance,
Sri

I am trying to use the TEXT datatype for a column to hold large amounts of ascii data.
Creating the table from script I use:
create table mytable
(
firstcolvarchar(30) not null,
secondcolTEXT not null
)
go
The field will not accept strings in length over 16 chars. I looked at the table design in the enterprise manager and it shows 16 chars as the width.
I tried creating the table with TEXT(32000) but I get "The size (32000) given to the column 'secondcol' exceeds the maximum. The largest size allowed is 8000." I thought that TEXT fields are what you use when the length is over 8000. What do I need to do to enable this type of data storage? thanks in advance.

OK, I`ve been researching the use of the TEXT datatype all day and would
like opinions on what I`ve found.
First, a little background. I have been tasked with writing an ASP
application to handle the display of FAQs for a company`s products. I would
like to store all info in a table much like
faqID int
question TEXT
answer TEXT
Simple enough, right? I then tried to create a stored procedure to add a
new FAQ and all hell broke loose. ASP would not pass anything larger than
255 chars to the stored procedure.
I read in the "ADO and SQL Server Developer`s Guide" from Microsoft about
using varchar datatypes of 255 chars (instead of TEXT) and chunking large
text up to fit in these smaller datatypes. This seems like a lot of work.
I also read in "Inside SQL Server 6.5" that "The text datatype is sometimes
awkward to work with. Many functions don`t operate against text, stored
procedures are limited in what they can do with text, and some tools don`t
deal with it well." (page 632). This statement concerns me greatly. How
are stored procedures limited in dealing with TEXT? Do the standard SQL
UPDATE and INSERT commands work or must READTEXT and UPDATETEXT be used
instead?
I guess my question is, what is the best way to accomplish this? I have a
feeling that others have had to do this before. Is SQL Server not meant to
handle large textual objects? Is chunking the best way to go? Will version
7.0 handle this scenario better?
Any help greatly appreciated!

I'm trying to do a simple search for any record that has an empty 'dsc' field. There isn't a NULL character in there, just a SPACE character. The 'dsc' field is a description field so it's datatype is TEXT.
Code:
SELECT id FROM leads WHERE dsc<>''
Normally I can do a VARCHAR(50) like that and get the results I'm looking for. When I do this on a TEXT datatype I get this error:
The text, ntext, and image data types cannot be compared or sorted, except when using IS NULL or LIKE operator.
I I tried a couple of things, but it's not getting me the correct results.
Code:
SELECT id FROM leads WHERE dsc NOT LIKE '% %'
SELECT id FROM leads WHERE dsc NOT LIKE '% '
SELECT id FROM leads WHERE dsc NOT LIKE ' %'
Please shed some light on this.. thanks!
Edited @ 12:08 PM
After some research I found an unconventional way of beating the system. If you have a more conventional way I would still like to see it. A quick fix is using DATALENGTH() function to compare the data. Basically if there are any characters besides NULL and space then the data length will be more than zero.
Code:
SELECT id FROM leads WHERE DATALENGTH(dsc)=0

Body(text,null)
This field is used for notes. For certain records users will enter a date.

I'm looking to do a select statement that will grab only those records with a date and make them an int field. This doesn't seem to work.

I have a number of bit datatypes ( Boat types: Cruiser, Sportfisher, Megayacht, Sailboat) that I would like to place in a text box and do away with the individual selections. For instance, some marinas cater to "Cruiser", "Megayacht" and "Sailboat" while others include the "Sportfisher" also and there are many other combinations of vessels. I am stumped at how to write a query that takes the existing "True" values for each boat type and places them in a text box in the form of
" Cruisers, Megayachts, Sailboats" .
Thanks in advance for possible solutions.
