What i want to do is i pass input of tableB, column3 and i get name of Primary tableA and field name IDa. How is it possible to do in tsql ?
I have a very strange situation. I've increased the size of an NVARCHAR field from 8 to 9 in a database table. The format of the data that I enter will either be an 8 character field (123456-8) or a 9 character field (1234567-9). The '-' is critical.
It used to only accept the 8 character version, but after increasing the field size, if I try to insert the 9 character field version, it gets truncated after the '-', as though it's still only allowing 8 characters. But that only occurs when I include the '-' or other such characters like '#'. If I try to insert 1234567a9, it works. The following explains the outcomes:
Inserted Value -> Result in table
123456-8 -> 123456-8 *Correct
1234567-9 -> 1234567- *Wrong
123456789 -> 123456789 *Correct
1234567#9 -> 1234567# *Wrong
1234567a9 -> 1234567a9 *Correct
Why is it that characters such as '-' and '#' are truncating the value, but only if the string is 9 chars long?
I'm currently using a direct t-sql insert statement in SQLExpress. The field is a simple NVARCHAR(9) field.
The source column is varchar(1) but i need this as nvarchar(1).. How can I cast this as NVARCHAR...

I have a stored procedure that returns XML using FOR XML Explicit. I need to use the output of this procedure in another procedure, and modify the xml output before it is saved somewhere.
Say StoredProc1 is the one returning xml output and StoredProc2 needs to consume the output of StoredProc1
I declared a nvarchar(max) variable and trying to saved the result of StoredProc1
Declare @xml nvarchar(max)
EXEC @xml = StoredProc1 @Id
This doesn't work as expected as @xml doesn't get any value assigned or rather I would say
EXEC @xml = StoredProc1 @Id
outputs the entire xml whereas it should just save the xml in a variable.
In my SQL 2005 database table Records, I have 3 fields, field1, field2, and field3 which are all nvarchar(50) fields. The value of field2 is something like this, MDB006-MD002-0004-3-2007. I would like to order this field but only use the 0004-3-2007 part of the field to order it. Is it possible to put the last 11 charachters (0004-3-2007) in another field and then order it using this new field?

Hi!
Is there any way to store UTF-8 encoded string in Nvarchar field? Or strings can be stored only in Unicode?
There are two fieldsA1 nvarchar(30)A2 nvarchar(800)I know nvarchar field is alterable length, if I store a string mystring='abc' to A1 field or to A2 field, I think they use the same disk space, so I think it's always a good way to define a big length nvarchar field such as A3 nvarchar(4000) for any length string, becuase they always use the same disk space, is it right?

Hi everyone.
So as the subject says, I have a few fields that are nvarchar but hold date information. Most of these fields I have been able to move to datetime easiliy enough, simply by going into edit mode for the table and converting the fields to datetime. But 1 field is giving me problems I keep getting this error.
quote:- Unable to modify table.
Arithmetic overflow error converting expression to data type datetime.
The statement has been terminated.
I really dont know why I'm getting this error, but I"m assuming it may have to be something like one of the records may not be in date format. But I don't know if this is the case and I don't know how to locate where my problem is coming from.
Any guidance is greatly appreciated.
Thanks.
I have data saved in nvarchar field in SQL Server and I am displaying it using <= dbReader["my_field"] but even the three or four paragraphs comes as one paragragh and I don't know know where are my line breaks going?

I copying data from our Informix 7.2 database into SQL Server 2K using DTS but hitting errors during the process. There appears to be date data within Informix that will not convert properly when moving into SQL. Since the error is appearing at the 1.5million (approx.) record. I figured on changing from datetime to nvarchar. Works like a charm! :-)
My new problem is converting it back to datetime so I can query against the date without having to create scripts to parse the field.
The data in SQL currently looks like this -> 2000-11-29 (nvarchar(50))
I would like to have it -> 11/29/00 (datetime)
Any help is greatly appreciated!

View 2 Replies View RelatedMS SQL 2000. Does anyone know how to find all rows where an nvarchar column contains a specific unicode character? Is it possible without creating a user defined function? Here's the issue. I have a table Expression (ExpID, ExpText) with values like 'x < 100' and 'y ≤ 200'. where the second example contains Unicode character 8804 [that is, nchar(8804)]. Because it's unicode, I don't seem to be able to search for it with LIKE or PATINDEX. These fail:
SELECT * FROM Expression WHERE ExpText LIKE '%≤%' -- no recordsSELECT * FROM Expression WHERE PATINDEX('%≤%', ExpText) -- no records
However, SELECT PATINDEX('%≤%', 'y ≤ 200') will return 3.
Any suggestions? Thanks in advance.
since ten years perhpas the society has a database with some table (person, country, and so on)since last years , the project manager decides to create a new database with some new design because before some information was save in one table well, the problem is when we pass all application to the new model we've notice that some id are not the same !
sample :
table Language old model
-------------------------
id frenchDescription english description
----------------------------------------
3 Anglais English
.....
......
table Language new model
id frenchDescription english description
-----------------------------------------
5 Anglais English
.....
.....
Alright , you can understand that the new model must be the same id => 3
my question is how to modify id on the table ?
I found a few 'SearchAllTables' scripts out there to find a value in any table/column/row of any Database.
My problem is that none of these database search queries seem to look at primary key values.
The value I'm looking for is a primary key - I need to find all the other tables that have this primary key value.
how I could accomplish this?
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.
Hi,
As you can see, I'm totally new at Sql Server.
I have a problem, I store text into a nvarchar field (could be a 200 or 20,000 characters long string), inside the text there are several carriage returns which I would like to preserve to later presentation, but when retreiving the data from sql server I got the "cr" as "?", also I opened the database from Sql Managment and all cr's were saved as "?".
What can I do to preserve the cr inside each field ?
Thanks in advance.

Hello,
I have an app that is connected to SQL 2005 express edition.
In the DB there is a table that has an auto incremental primary key
What I want is, I want to get a new value for that auto incremental field before sending the new record's date to the DB to be stored. So I can display the new record's ID in my app's interface
So is there something in SQL server like SEQUENCE in oracle.
Thanks in advance.
I need to insert a row of data and return the value of the primary key id of the row.

View 4 Replies View RelatedI'm really puzzled with this. I am new to using MS SQL and need help with the primary key. When I was using Access, I would open the database table and just enter values for the various columns, each time a new column was begun, the computer would insert a unique number there. OK, so now I am using visual studio to work on a SQL database. I created a new table and the first field I specified was "ID", I then chose it as the primary key. For default value, I tried both auto number and auto increment. These don't seem to work, as when I type values into fields and try to move to the next row, having left the ID field blank, I get an error which reads "String or Binary data may be truncated". What is going on, what do I need to do so the field automatically populates with an ID number... Some research sort of led me to the concept of a "trigger" to do this. Is this the approach. I was able to r-click on the table and I saw an option for "create trigger" or "new trigger"... How do I learn to do this, is there a generic trigger to do an auto increment of a primary key ID field?
