From what I read, you need to encode the unicode text in UTF8 format and then save it into a regular CHAR or VARCHAR field, and you need to decode the UTF8 text when you want to use the data later (like, convert it to UTF16 format).
Is that true? Is there a NCHAR or NVARCHAR type in Oracle that corresponds to the same type in SQL Server?
Thanks.

There are unicode types in Oracle, nchar and nvarchar2 are there. You should create database with a unicode - characterset (i.e. AL32UTF8) for better performance and sorting.

I want to encrypt a connection string so the password won't be sent in plain text. How would I attempt this? Thanks
|
|

I'm presuming you're talking about what's sent over the wire.
If you're talking about SQL Server 2000, the password isn't sent in plain text. However it looks like the encryption is pretty trivial - I can see that every character always encodes to the same byte every time, and that the 0 bytes (the password is sent as UTF-16, so for a password that uses only ISO-8859-1 [Latin-1] characters every other byte is a 0) are always 0xa5. So it's really not secure.
Instead of sending a username and password, you should consider using a trusted connection (set Integrated Security=SSPI) which will use a better protocol for authentication - NTLM or I think even Kerberos. However, you can't specify the username to be used - the security identity of the current thread will be used.
[EDIT] You can also enable SSL. See 'Net-Library Encryption' in Books Online. [/EDIT]

Hey all, I have a problem with openxml. In my ASP.NET application I use XmlSerializer to turn a object into XML, things work fine. I then send the xml to a stored procedure on the SQL server (2000). The weird thing is the same XML can be sent to two different SPs and one does not work when declaring one of the XML fields as ntext.
ie. in one I do an insert,
insert into table1 (cust_id, job_requested, job_status)
select @useCustId,
xmlDetails.Description,
xmlDetails.StatusId,
from OPENXML(@idoc, 'JobList/Job', 2)
WITH (CustomerId int, Description ntext, StatusId int) xmlDetails
Now this is trimed down, but it works fine. now when the same XML gets sent to another SP that updates like:
update job_main set
job_requested = xmlDetails.Description,
job_status = xmlDetails.StatusId,
from OPENXML(@idoc, 'JobList/Job', 2)
with (Id int, Description ntext, StatusId int) xmlDetails
where job_id = xmlDetails.Id
Now this one fails with 'Internal SQL Server error.' And I have no idea why, as it is the same XML as in the insert statement. If i change the ntext to nvarchar or varchar it works, but text and ntext do not.
Anyone seen anything like this, or know if i'm doing something stupid? I have no idea.
Thanks all

Concat them together in your query.

I'm going to guess that JZooL should have been 'JZ001'. Looking for JZ001 and JZ006 on a search engine found this page[^] on Sybase's support site for their JDBC provider.
JZ001 sounds like a configuration error or someone typing the wrong user name. It looks like the user name is limited to 30 characters for this database.
JZ006 sounds like a general network error - that the server cannot be contacted. Check that the correct server name/IP is specified in the configuration. If it is, this is a task for your network administrators (if any) to work out why the one cannot see the other. Presumably this worked before the summer break? Check that no firewalls have been added or reconfigured between the client and the server. See whether a ping works (it may not do even if the server is working and contactable since it's now common for firewall software or hardware to reject pings).

Hi All,
I am getting the following error,
Msg 245, Level 16, State 1, Line 13
Syntax error converting the nvarchar value 'INSERT INTO [mydb].[dbo].[temp]
(
[f1],
[f2],
[f3],
[f4]
)
VALUES(
222,
333,
44,
' to a column of data type int.
while executing the below code
DECLARE @t_f1 as int
DECLARE @t_f2 as nvarchar(50)
DECLARE @t_f3 as nvarchar(50)
DECLARE @t_f4 as nvarchar(50)
set @t_f1 = 111
set @t_f2 = 222
set @t_f3e = 333
set @t_f4 = 44
declare @q as nvarchar(500)
set @q = 'INSERT INTO [mydb].[dbo].[temp]
(
[fld1],
[fld2],
[fld3],
[fld4]
)
VALUES(
'+@t_f1+',
'+@t_f2+',
'+@t_f3+',
'+@t_f4+'
)'
exec @q
My database table structure is as follows,
CREATE TABLE temp
(
fld1 int,
fld2 nvarchar(50),
fld3 nvarchar(20),
fld4 nvarchar(20),
)
Thanks in advance...

Hi!!!!
Execute statement only takes nvarchar,char....datatype only
so u change data type like
DECLARE @t_f1 as nvarchar(50)
DECLARE @t_f2 as nvarchar(50)
DECLARE @t_f3 as nvarchar(50)
DECLARE @t_f4 as nvarchar(50)
Regards

Is there any other alternative means for integer data type?

You probably can use the CONVERT() function to convert the int variable to nvarchar.
Try CONVERT(@t_f1 AS NVARCHAR(50))

Hi,

Yes, I know. But from what I see it seems that the SQL is complaining that you are adding the nvarchar 'INSERT INTO [mydb].[dbo].[temp]..' into @t_f1 (which is an integer) when concatenating the @q.
The convert is just to make sure your @q can be created by concatenating nvarchars instead of adding it to an int.
When you execute it it should insert an integer instead of an nvarchar.
Btw, why are you using exec @q anyway? You don't seem to need to create a dynamic SQL statement for that one.

You should try using @ParamName when declaring parameters so it is clear.
You are missing the intUser as parameter and you should not put single apostrophe (') in between parameter name, that's why it is taking intUser as a string instead of parameter name
Try this:
sqlStr = "INSERT INTO FIN_FiscalYear (Name, StartDate, EndDate, CreatedOn, CreatedBy, CreatedIPAdd) VALUES(@Name, @StartDate, @EndDate, @CreatedOn, <code>@User</code>, @CreatedIPAdd)"
sqlCmd.Parameters.Add("@Name", strName)
sqlCmd.Parameters.Add("StartDate", strStartDate)
sqlCmd.Parameters.Add("EndDate", strEndDate)
sqlCmd.Parameters.Add("CreatedOn", strCreatedOn)
<code>sqlCmd.Parameters.Add("User", intUser)</code>
sqlCmd.Parameters.Add("CreatedIPAdd", strCreatedIPAdd)

I have removed the single apostrophe (') on the sqlStr line and replaced them with a leading (@) in the VALUES section. I have also placed the (@) infront of all the names inside the quotes on the sqlCmd.Parameters.Add statements.
Now the error message is: "Must declare the variable '@Nmae'."
My new lines:
sqlStr = "INSERT INTO FIN_FiscalYear (Name, StartDate, EndDate, CreatedOn, CreatedBy, CreatedIPAdd) VALUES(@Name, @StartDate, @EndDate, @CreatedOn, @CreatedBy, @CreatedIPAdd)"
sqlCmd.Parameters.Add("@Name", strName)
sqlCmd.Parameters.Add("@StartDate", strStartDate)
sqlCmd.Parameters.Add("@EndDate", strEndDate)
sqlCmd.Parameters.Add("@CreatedOn", strCreatedOn)
sqlCmd.Parameters.Add("@CreatedBy", intUser)
sqlCmd.Parameters.Add("@CreatedIPAdd", strCreatedIPAdd)

You have made a spelling mistake in your sql statement. Check your sql and change @Nmae into @Name and things should be running smoothly.

The spelling mistake was my typing of the message. The copy/paste from the section of code shows the correct spellings. Pasted again here:
The error message is: "Must declare the variable '@Name'."
sqlStr = "INSERT INTO FIN_FiscalYear (Name, StartDate, EndDate, CreatedOn, CreatedBy, CreatedIPAdd) VALUES(@Name, @StartDate, @EndDate, @CreatedOn, @CreatedBy, @CreatedIPAdd)"
sqlCmd.Parameters.Add("@Name", strName)
sqlCmd.Parameters.Add("@StartDate", strStartDate)
sqlCmd.Parameters.Add("@EndDate", strEndDate)
sqlCmd.Parameters.Add("@CreatedOn", strCreatedOn)
sqlCmd.Parameters.Add("@CreatedBy", intUser)
sqlCmd.Parameters.Add("@CreatedIPAdd", strCreatedIPAdd)

If you have not resolved this issue by now, as memory serves the santax should be like this.
sqlStr = "INSERT INTO FIN_FiscalYear (Name, StartDate, EndDate, CreatedOn, CreatedBy, CreatedIPAdd) VALUES('@Name', 'StartDate', 'EndDate', 'CreatedOn', CreatedBy, 'CreatedIPAdd')"
sqlCmd.Parameters.Add("@Name", strName)
sqlCmd.Parameters.Add("StartDate", strStartDate)
sqlCmd.Parameters.Add("EndDate", strEndDate)
sqlCmd.Parameters.Add("CreatedOn", strCreatedOn)
sqlCmd.Parameters.Add("CreatedBy", intUser)
sqlCmd.Parameters.Add("CreatedIPAdd", strCreatedIPAdd)
The ambiguity comes in with reserved words like Name, Date, and Time etc. The ' is used for strings now integers.

I have a table called IMSUB with fields SUB, SUBV, & SUBD
pri key is SUB, SUBV
SUB = subassy number, not auto number
SUBV = subassy version, not autonumber
SUBD = new name of subassy
I want to insert a new subassy, therefore, I need to get the maximum value for SUB add 1 to it, set SUB = 1 and set the SUBD to the new name. How can I do this in SQL? MS Access! Thx to all!
