My problem now is getting the last character of a ntext variable.

I do it this way, but it doesn't seem to work:

SUBSTRING(@strvar, DATALENGTH(@strvar), 0)

Have a nice day!

<br />
DECLARE @strvar VARCHAR(50)<br />
SET @strvar = 'hello world'<br />
<br />
SELECT SUBSTRING(@strvar, LEN(@strvar), 1)<br />

Alright, now I try to compare it to a '\' using LIKE, and it never works.
How can I check if this character is '\' or not?

Have a nice day!

DECLARE @strvar VARCHAR(50)
SET @strvar = 'hello world'

SELECT CASE SUBSTRING(@strvar, LEN(@strvar), 1) WHEN '/' THEN 1 ELSE 0 END

Why do I need the SELECT?
Won't
WHILE(SUBSTRING(@strvar, LEN(@strvar), 1) NOT LIKE '\')
work?

Have a nice day!

You don't need SELECT, I'm just using it like a Debug.Print to see the value returned. Why are you using LIKE? You aren't making any kind of pattern comparison. You are comparing the result with a constant expression. You should be doing it this way:

SUBSTRING(@strvar, LEN(@strvar), 1) <> '\'

Thanks for looking

I have a weird situation here

I have some views and SPs
They have a name (Example: spCars), but when i generate the script for that object the create view script has another name (spCarsByBrand)
I know this happens beacause i changed the name after i created them

How can i preevent this??
Whats the correct way to rename SPs and views?
Do i have to delete and recreate with new name?

Thanks again

That's the best way to do it in my view, but you should be able to use sp_rename if you don't like the idea of DROP/CREATE. Here's an example of both:

sp_rename

<br />
CREATE PROCEDURE myTestProc<br />
@Id int<br />
as<br />
<br />
SELECT @@SERVERNAME<br />
<br />
GO<br />
<br />
EXEC sp_rename 'myTestProc', 'myRenamedTestProc', 'OBJECT'<br />
<br />
IF OBJECT_ID(N'myTestProc') IS NOT NULL<br />
BEGIN<br />
	SELECT 'Rename failed'<br />
	DROP PROCEDURE myTestProc<br />
END<br />
IF OBJECT_ID(N'myRenamedTestProc') IS NOT NULL<br />
BEGIN<br />
	SELECT 'Rename worked'<br />
	DROP PROCEDURE myRenamedTestProc<br />
END<br />

DROP/CREATE

<br />
CREATE PROCEDURE myTestProc<br />
@Id int<br />
as<br />
<br />
SELECT @@SERVERNAME<br />
<br />
GO<br />
<br />
IF EXISTS(SELECT * FROM sys.objects WHERE [object_id] = OBJECT_ID(N'myTestProc')) BEGIN<br />
	DROP PROCEDURE myTestProc<br />
END <br />
GO<br />
<br />
CREATE PROCEDURE myRenamedTestProc<br />
@Id int<br />
as<br />
<br />
SELECT @@SERVERNAME<br />
<br />
GO<br />
<br />
IF EXISTS(SELECT * FROM sys.objects WHERE [object_id] = OBJECT_ID(N'myTestProc')) BEGIN<br />
	DROP PROCEDURE myRenamedTestProc<br />
END <br />
GO<br />
<br />

Thanks for your answer

I cant believe all that one has to do to make sql work correctly Frown | :-(

I hadnt noticed that behavior until now that im exporting my DB using the generate sql script

By the way, sql script generator also has a lot of problems, doesnt it??
When dropping tables and other objects it doesnt care about dependencies and neither does it when creating them

Im having a hard time with generating the scripts for my DB
sql 2000 enterprise manager (Doesnt care about the deletion or creation order)
sql 2005 express ed (Doesnt care about the deletion or creation order)
Database Publishing Wizard (This one fails when trying to generate the script for a function that return a table, and i dont think that it generates scripts in the right order)

Do you have any sugestions for this?

Thanks again

Renaming objects will always cause problems. If you need to find dependencies here are a couple scripts to allow you to search the source of views and stored procs. Just enter the name of the object you're looking for and you'll get a list of objects which contain your search phrase.

Search stored procedure:

DECLARE @find VARCHAR(1000)SET @find = 'enter your search phrase here'<br />
<br />
SELECT sp.name,<br />
ISNULL(smsp.definition, ssmsp.definition) AS [Definition]<br />
FROM sys.all_objects AS sp<br />
LEFT OUTER JOIN sys.sql_modules AS smsp ON smsp.object_id = sp.object_id<br />
LEFT OUTER JOIN sys.system_sql_modules AS ssmsp ON ssmsp.object_id = sp.object_id<br />
WHERE(sp.type = N'P' OR sp.type = N'RF' OR sp.type='PC')<br />
AND ISNULL(smsp.definition, ssmsp.definition) LIKE '%' + @find + '%'

Search view:

<br />
DECLARE @search VARCHAR(1000)SET @search = 'enter your search phrase here'<br />
<br />
SELECT c.[Text]<br />
FROM dbo.sysobjects AS vINNER JOIN dbo.syscomments c ON c.id = v.id<br />
	AND CASE WHEN c.Number > 1 THEN c.Number			ELSE 0 END = 0<br />
WHERE v.type = 'V' AND c.[Text] LIKE '%' + @search + '%'<br />

As far as dropping and recreating objects as long as your script creates tables before your other objects. What I always do when writing my scripts is follow the IF EXISTS DROP then CREATE pattern. That way when I have a large script which creates a large number of objects if I get errors due to dependencies the first time I run it then I just run it again. The first time creates all the objects, the second time will create any that failed on the first attempt.

If you don't like this, then when you generate your scripts run them on a test database. Create 2 script files - one with DROP statements and one with CREATE statements. Run your CREATE script and look for dependency errors. If you get any, run your DROP script then rearrange your CREATE statements to fix the dependency errors and run the CREATE script again. Rinse, wash, repeat.

how to encrypt and decrypt stored procedure in sql server 2000

Here's how to encrypt the procedure:

<br />
CREATE PROCEDURE myTestProc<br />
@Id INT<br />
WITH ENCRYPTION<br />
AS<br />
<br />
   SELECT @@SERVERNAME<br />
<br />
GO<br />

But you have to save the source code in a script file somewhere. There is no way to decrypt the source. Not even for sysadmin or dbowner.

Insert or Export data to SQL Server 2000 (Arabic Language)

Dear All,
I want to export data from Access into SQL Server 2000, but some data contains Arabic Text words, and it is not exported correctly as Arabic Language, it is stored as symbols like "??????". And this problem also happens when I use an Insert statement using SQL Query Analyzer.
Is there a way to insert these Arabic Data as it is in Arabic??
The following is such an example of my insert statement:

INSERT INTO Table( HOTCODE, HMONTH, HYEAR, HOT_NAME, OWNER_MNGR, STREET, BUILDING_OWNER,
BUILDING_NO, POBOX, PHONE, FAX, E_MAIL, LEGAL_STATE, LICE_NO, YEAR_ESTAB, YEAR_START, CLASS, HLOCAL,
SEX_OWNER, MINGR_NAME, SEX_MINGR, WEB, OWNER_BUILD, OWNER_HOTEL, RESULT ) VALUES (
'3009', '4', '2007', '???? ??', '??? ?????? ????', '????? ???? ???????', '??? ??????'
, NULL, '2169', '2409191', '2409189', 'cityinn@p-01.com', '5', '252', '1994', '1997'
, '4', '301790', '1', '????? ??? ????', '1', '1', '2', '1', '2');

Note: The key words in the insert statement are some Arabic words, but they are converted to "????"
when I post the current message.

Thanks

You have 2 options. You can either store all your text data as NCHAR, NVARCHAR and NTEXT or use the correct collation for arabic. This should help: http://technet.microsoft.com/en-us/library/ms187582.aspx[^]

Work with query results inside a stored procedure

Re: Work with query results inside a stored procedure

1-Apr-08 22:40

Hello!

I need to write a stored procedure that will make a query, and then return a value depending

on the query result.

My question is how can I store the query results inside the stored procedure for me to be able

to examine them and then return an appropriate result?

Thanks in advance!

Have a nice day!

You want to store your query and then query that in a stored procedure? Can you not just do a bigger better query?

You can use cursors to do iterative stuff if need be but its best avoided.

Regards,
Rob Philpott.

Declare a temp table and save the result set inside that table. Make sure to drop it before you exit the stored procedure.
