I have a problem when I try to insert arabic text as sql variable in sql server 2008 , inserts data like this value ???? .How to solve this?
This is my query
insert into tests values(N''+#name)
The result shows like this:
Try this and you will see what Data Type you shoule use :
DECLARE #V1 VARCHAR(50) = 'فيلم';
DECLARE #V2 NVARCHAR(50) = N'فيلم'
SELECT #V1 Varchar_Col, #V2 NVarchar_Col
Demo
Update:
Try to use SqlDbType.NVarChar when you pass your Parameter.
and you can also try with :
INSERT INTO tests (ID_Number) VALUES (#name)
Use unicode datatypes for your data storage and begin your strings with N literal like this:
declare #t table(col Nvarchar(100));
insert #t (col) values (N'your text');
Or use the appropriate COLLATION with non-unicode data types but pass your values as unicode ones (with N) because your server/database collation seems to be different from arabic

Is there any way to make following query Work?
declare #t nvarchar(20)
set #t='حس'
SELECT [perno] ,[pName]
FROM [dbo].[People]
Where [pName] like N''+#t +'%'
I cann't use like this:
Where [pName] like N'حس%'
Or using an stored procedure :
ALTER PROCEDURE [dbo].[aTest]
(#t nvarchar(20))
AS
BEGIN
SELECT [perno] ,[pName]
FROM [dbo].[People]
WHERE ([People].[pName] LIKE N'' +#t + '%')
END
You don't need to use N prefix in the WHERE clause since your variable is already nvarchar, and you are passing a variable not a literal string.
Here is an example:
CREATE TABLE People
(
ID INT,
Name NVARCHAR(45)
);
INSERT INTO People VALUES
(1, N'حسام'),
(2, N'حسان'),
(3, N'حليم');
DECLARE #Name NVARCHAR(45) = N'حس';--You need to use N prefix when you pass the string literal
SELECT *
FROM People
WHERE Name LIKE #Name + '%'; --You can use it here when you pass string literal, but since you are passing a variable, you don't need N here
Live demo
You may have seen Transact-SQL code that passes strings around using an N prefix. This denotes that the subsequent string is in Unicode (the N actually stands for National language character set). Which means that you are passing an NCHAR, NVARCHAR or NTEXT value, as opposed to CHAR, VARCHAR or TEXT.
From docs
Prefix Unicode character string constants with the letter N. Without the N prefix, the string is converted to the default code page of the database. This default code page may not recognize certain characters.
To answer your question in the comment with a simple answer, you are using the wrong datatype, so ALTER the stored procedure and change the datatype of your parameter from VARCHAR to NVARCHAR.
UPDATE:
Since you are using an SP, you can create your SP (according to your comment) as
CREATE PROCEDURE MyProc
(
#Var NVARCHAR(45)
)
AS
BEGIN
SELECT *
FROM People
WHERE Name LIKE ISNULL(#Var, Name) + '%';
--Using ISNULL() will return all rows if you pass NULL to the stored procedure
END
and call it as
EXEC MyProc N'حس'; --If you don't use N prefix then you are pass a varchar string
If you see, you need to use the N prefix when you pass literal string to your SP not inside the SP or the WHERE clause neither.
Demo for the SP
in these lines
declare #t nvarchar(20)
set #t='حس'
the 'حس' is a varchar constant that you then assign to an nvarchar variable. But you already lost data with the original conversion to that varchar constant and you cannot get that back.
The solution is to use an nvarchar constant:
set #t=N'حس'
It might be much simpler:
Try this
declare #t nvarchar(20)
set #t='حس';
SELECT #t; --the result is "??"
You are declaring the variable as NVARCHAR correctly. But the literal does not know its target. Without the N it is taken as a VARCHAR with the default collation.
The following line
Where [pName] like N''+#t +'%'
will search for a pName LIKE '??%'.
The solution should be
set #t=N'حس'; --<-- N-prefix
I am working on an application that populates values from sql Database in a format two numeric and alpha character e.g 11G,34H. There is no validation or check for the same.I want to put put checkpoint/validation from Database end.Is it possible to implement via SQL procedure or anything.Can anyone help me with the code.
Try the below query
DECLARE #strtable TABLE (column1 VARCHAR(50))
INSERT INTO #strtable
VALUES ('11H'),('sda'),('175HH'),('1H1'),('282')
INSERT INTO YourTable (Column1)
SELECT Column1
FROM #strtable
WHERE LEN(column1)=3
AND ISNUMERIC(LEFT(column1,2))=1
AND ISNUMERIC(RIGHT(column1,1))!=1
--Output : 11H
When user insert Russian word like 'пример' to database,database saves it like '??????'. If they insert with 'N' letter or I select it with 'N' letter, ie; exec Table_Name N'иытание' there is no problem. But I don't want to use 'N' in every query, so is there any solution for this? I will use stored procedure by the way.
UPDATE:
Now I can use Russian letters with alter collation. But I can't alter collation for every language and I just want to learn is there any trigger or function for automatic add N in front of the text after text add. IE; when I insert 'пример', SQL should take it like N'пример' autamaticly.
You have to use column's datatype NVARCHAR to insert unicode letters, also you have to use N'value' when inserting.
You can test it in following:
CREATE TABLE #test
(
varcharCol varchar(40),
nvarcharCol nvarchar(40)
)
INSERT INTO #test VALUES (N'иытание', N'иытание')
SELECT * FROM #test
OUTPUT
varcharCol nvarcharCol
??????? иытание
As you see column of datatype varchar returning questionmarks ?????? and column of datatype nvarchar returning russian characters иытание.
UPDATE
Problem is that your database collation does not support russian letters.
In Object Explorer, connect to an instance of the SQL Server Database Engine, expand that instance, and then expand Databases.
Right-click the database that you want and click Properties.
Click the Options page, and select a collation from the Collation
drop-down list.
After you are finished, click OK.

it would very difficult to put in comment i would recommend this link Info
declare #test TABLE
(
Col1 varchar(40),
Col2 varchar(40),
Col3 nvarchar(40),
Col4 nvarchar(40)
)
INSERT INTO #test VALUES
('иытание',N'иытание','иытание',N'иытание')
SELECT * FROM #test
RESULT
To store and select Unicode character in database you have to use NVARCHAR instead of VARCHAR. To insert Unicode data you have to use N
See this link https://technet.microsoft.com/en-us/library/ms191200%28v=sql.105%29.aspx
The n prefix for these data types comes from the ISO standard for National (Unicode) data types.
Change type of your columns (containing Russian) from varchar to nvarchar.
I am writing a procedure with a simple insert statement. It will take #Target as parameter of type nvarchar(200) and this parameter will be inserted to table.
My problem is how to insert Japanese character if parameter is receiving values like this - 'ンプライ'
INSERT INTO [TableName] (Target) VALUES (#Target)
using MS SQL Server 2008
Try
insert into target (Target) values(N 'ンプライ')
Make sure your target datatype is Nvarchar
insert into TableName (Target) values (N 'ンプライ')
What's wrong with this T-SQL :
DECLARE #temp TABLE(ID INT IDENTITY,[Value] VARCHAR(100))
SET #temp = dbo.[fnCSVToTable](',2,3')
I don't think you can assign to the table variable like that (unless it is a new thing in SQL 2008).
At least for SQL2005 you would need to do the following.
DECLARE #temp TABLE(ID INT IDENTITY,[Value] VARCHAR(100))
INSERT INTO #temp
SElECT [value]
FROM dbo.[fnCSVToTable](',2,3')
From the docs for SET (SQL 2008; SQL 2005) (my emphasis):
# local_variable
Is the name of a
variable of any type except cursor, text, ntext, image, or table.
To populate a table variable, use
INSERT #table_variable
SELECT columns
FROM dbo.fnTableValuedFunction
