I created a database with collation: default & a table with a column has nvarchar(50) as its data type. But when I select the data I got "???".
Can anybody tell me what's wrong?
You must always declare N before inserting any values.
INSERT INTO MYTABLE (Col1) VALUES (N'your text')

In SQL Server, I am trying to create a table that can store unicode characters. Specifically this one
https://www.fileformat.info/info/unicode/char/0144/index.htm
However if I pick nvarchar as the column type, then store it and then select it, it shows as a regular n.
How can I get it to store properly?
This works fine
DECLARE #t TABLE
(
InputChar NVARCHAR(10)
)
INSERT INTO #t (InputChar)
VALUES (N'ń')
INSERT INTO #t (InputChar)
VALUES ('ń')
SELECT * FROM #t
Are you making sure that when you inserting your strings you are specifying that the string is unicode ? e.g.N'yourstring'
My SQL Server changes same characters in the Strings.
Example:
insert into TEST_TABLE
values ('árvíztűrő tükörfúrógép2');
inserts
árvízturo tükörfúrógép
The TEST_TABLE has only one column with type varchar(50).
How can I insert strings into a table in SQL Server?
You will most likely need an nvarchar (rather than varchar) data type on the column that allows unicode characters.
You will probably need to specify it being unicode too by prefixing the value with an "N".
insert into TEST_TABLE
values (N'árvíztűrő tükörfúrógép2');
Change the column datatype to nvarchar and try this:
insert into TEST_TABLE
values (N'árvíztűrő tükörfúrógép2');
Run the following code on your table:
ALTER TABLE TEST_TABLE ALTER COLUMN *ColumnName* nvarchar(50)
After that, it works like a charm (even without prefixing the inserting string with N).
I need to design a table in SQL Server having some columns, one of these columns (ID column and use sequential uniqueidentifier) should automatically populate its data when inserting other column data.
The values of the ID column should be generated automatically when insertion happens.
Please help me to do this, any help is appreciated.
NB: I am new to this step by step approach will be more helpful
Just create a table with a column ID of datatype uniqueidentifier and set it's default value to newsequentialid():
Then, when you go insert rows into that table, just omit the ID column from the list of columns you're inserted values into:
INSERT INTO dbo.YourTable(ColA, ColB, ....., ColX)
VALUES(.., .. ,. ...)
If you don't explicitly insert a value into ID, the default specification (newsequentialid()) will be used .
As per Marc_s's comment, you should use NEWSEQUENTIALID()
CREATE TABLE myTable (ColumnA uniqueidentifier DEFAULT NEWSEQUENTIALID());
See NEWSEQUENTIALID (Transact-SQL)
I am using SQL SERVER 2005 and i am also newbie to SQL SERVER
now i need to know that is there any way or any technique in SQL SERVER 2005
such that as soon as i add new record in table then current date-time should be added in to any given field of table.
Example:
Suppose i have CUSTOMER table
and it has fields say CustomerID,CustomerName,....,DateTime.
now whenever new customer added in this table then current date-time should be automatically added in to DateTime Field of CUSTOMER table.
In SSMS one can set the Default value or binding property of the appropriate column of the table property to getdate().
You need to add default constraint:
alter table MyTable add constraint MyColumnDefault default getdate() for MyColumn;
I'm not much of an expert in SQL but you could use TIMESTAMP for this, see:
http://msdn.microsoft.com/en-us/library/ms182776%28v=sql.90%29.aspx
It sounds like you should have a look at the timestamp data type:
http://msdn.microsoft.com/en-us/library/ms182776%28v=sql.90%29.aspx
Check table definition with default value
Declare #Table Table
(
Id int identity,[Name] varchar(100),CreatedDate DateTime default (Getdate())
)
insert into #Table([Name])
values ('yogesh')
insert into #Table ([Name])
values ('Bhadauriya')
insert into #Table ([Name])
values ('Yogesh Bhadauriya')
select *
From #Table
In SQL Server 2005 I have an "id" field in a table that has the "Is Identity" property set to 'Yes'. So, when an Insert is executed on that table the "id" gets set automatically to the next incrementing integer. Is there an easy way when the Insert is executed to get what the "id" was set to without having to do a Select statement right after the Insert?
duplicate of:
Best way to get identity of inserted row?
In .Net at least, you can send multiple queries to the server in one go. I do this in my app:
command.CommandText = "INSERT INTO [Employee] (Name) VALUES (#Name); SELECT SCOPE_IDENTITY()";
int id = (int)command.ExecuteScalar();
Works like a charm.
If you're inserting multiple rows, the use of the OUTPUT and INSERTED.columnname clause on the insert statement is a simple way of getting all the ids into a temp table.
DECLARE #MyTableVar table( ID int,
Name varchar(50),
ModifiedDate datetime);
INSERT MyTable
OUTPUT INSERTED.ID, INSERTED.Name, INSERTED.ModifiedDate INTO #MyTableVar
SELECT someName, GetDate() from SomeTable
Scope_identity() is the preferred way, see: 6 Different Ways To Get The Current Identity Value
SCOPE_IDENTITY(); is your best bet. And if you are using .NET just pass an our parameter and check the value after the procedure is run.
CREATE PROCEDURE [dbo].[InsertProducts]
#id INT = NULL OUT,
#name VARCHAR(150) = NULL,
#desc VARCHAR(250) = NULL
AS
INSERT INTO dbo.Products
(Name,
Description)
VALUES
(#name,
#desc)
SET #id = SCOPE_IDENTITY();
You have to select the scope_identity() function.
To do this from application code, I normally encapsulate this process in a stored procedure so it still looks like one query to my application.
I tend to prefer attaching a trigger to the table using enterprise manager. That way you don't need to worry about writing out extra sql statements in your code. Mine look something like this:
Create Trigger tblName
On dbo.tblName
For Insert
As
select new_id = ##IDENTITY
Then, from within your code, treat your insert statements like select statements- Just execute and evaluate the results. the "newID" column will contain the identity of the row you just created.
This is probably the best working solution I found for SQL Server..
Sql Server return the value of identity column after insert statement
