ALTER PROCEDURE Statement Within IF EXISTS
May 28, 2002
Hello.
I'm trying to create a batch sql script which first alters some existing tables via the ALTER TABLE command, I then want to alter some existing stored procedures via the ALTER PROCEDURE command within the same batch. I have found that I can encompas the alter table scripts within a conditional IF EXISTS (Begin/End) but not the alter procesdure scripts. I have looked in reference material and have found nothing to suggest this type of operation is not possible. Is this possible? Is this a know bug fixed by a service pack?
Thanks in advance for any replies.
David.

When I created an SP in Enterprise Manager, I didn't manually type in the existence check at the inception, a la "if exists (select * from sysobjects...)". I just started with the CREATE PROC AS statement.
I noticed that if I generate a SQL script for the SP, SQL2000 automatically generates the existence check statement.
My question is, can I assume that when the SP is actually executed, SQL2000 does the exists check on its own? I EXEC'd the proc in Query Analyzer with no errors.
I just want to make sure that I don't need to enter the exists statement if it's already being done behind the scenes.

Keep in mind this is my first compiled SQL program Stored Procedure(SP), copied from a book by Frasier Visual C++.NET in Visual Studio2005 (Chap12). So far, so theory, except for one bug (feature?)below. At some point I'm sure I'll be able to laugh about this, akinto forgeting a semi-colon in C/C++, but right now it's frustrating(time to sleep on it for a while).Problem--For some reason I get the error when trying to save files where twotables (called Author and Content), linked by a single key, form arelationship.By simple comparison of the source code in the textbook and my program(below) I found the difference: instead of, like in the textbook, theStored Procedure (SP) starting with "CREATE PROCEDURE", it*automatically* is (was somehow) given the name of 'ALTER PROCEDURE'and I cannot change this to "CREATE PROCEDURE" (you get an error in MSVisual Studio 2005 Pro edition of "There is already an object namedXXX in the database", see *|* below). No matter what I do, the SP isalways changed by Visual Studio 2005 to 'ALTER PROCEDURE'!!!(otherwise it simply will not save)Anybody else have this happen? (See below, others have had this happenover the years but it's not clear what the workaround is)Keep in mind this is my first attempt and I have ordered somespecialized books on SQL, but if this is a common problem (and Isuspect it's some sort of bug or quirk in VS2005), please let me know.Frankly I think SQL as done by VS2005 is messed up.Here are two Usenet threads on this problem:(1) http://tinyurl.com/2o956m or,http://groups.google.com/group/micr...1454182ae77d409(2) http://tinyurl.com/2ovybv or,http://groups.google.com/group/micr...9e5428bf0525889The second thread implies this is a bug--any fix?Also this bug might be relate to the fact I've switched (and notrebooted) from Administrator to PowerUser after successfully changingthe permissions in the SQL Server Management Studio Express (see thisthread: http://tinyurl.com/2o5yqa )Regarding this problem I might try again tommorrow to see if rebootinghelps.BTW, in the event I can't get this to work, what other SQL editor/compiler should I use besides MS Visual Studio 2005 for ADO.NET andSQL dB development?RL// source files// error message:'Authors' table saved successfully'Content' table- Unable to create relationship 'FK_Content_Authors'.The ALTER TABLE statement conflicted with the FOREIGN KEY constraint"FK_Content_Authors".

I'm trying to gather some user statistics based on 3 conditions. First I want to check if the referring querystring is already in the database. If not insert it into the db. Second, if the querystring is already in the database, then check if the ip-address of the user is already in the database. If it is, then check if the ip address was inserted today. If not, update the "refCountIn" field with +1. The problem lies in the third condition where we check if the ip-address was inserted today and if false, update the "refCountIn" field with +1 and if true, do nothing.Below is the code I have until now: 1 Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
2
3 ' *** Declare the variables
4 Dim getStatCmd As String
5 Dim updStatCmd As String

7 Dim myRef As String = Request.QueryString("ref")
8 Dim myQueryString As String = Request.ServerVariables("QUERY_STRING").Replace("ref=", "")
9 Dim myRemoteAddr As String = Request.ServerVariables("REMOTE_ADDR")
10 Dim myHttpReferer As String = Request.ServerVariables("HTTP_REFERER")
11
12 Dim dtNow As Date = DateTime.Now
13 Dim dtToday As Date = DateTime.Today

Anyone with an idea on how to solve this one? I think I need to write a subquery for the third condition, but I don't have a clue on how to handle this.Thanks in advance for your help!

Can someone give me a hand with this?
Ok I have a table called allstocks, with a primary key of ticker, I also have a todaysstocks table with a primary key of ticker.
Todaysstock table updates the allstocks table with this statement,
insert into allstocks (exchange,transdate,ticker,[opened date],[closed date],[over/under]) select exchange,[todays date],ticker,[opened date], [closed date],[over/under] from todaysstocks
this works fine, unless the ticker already exists. How do I write the statement, that if the ticker already exists, then update the rest of the fields with the new info, or delete the row and recreate it?
ANy help would be appreciated. Thanks

Hello,
I would like to set a variable within my if exists statement, however SQL is throwing and error stating:
Incorrect syntax near '='.
If I remove the if exists, the query runs fine. Is there a reason why this is not working the way I have it and what suggestions can I use to accomplish what I am trying to do, which is store the ID into the permissionID variable
Here is my code block:
Code Snippet
declare @permissionID int;
if exists(select @permissionID = Id from Permission
where [Description] = 'SettlementReport')
Thanks,

Hi List,
I am trying to add a column with Alter Table, like this:
ALTER TABLE myTable ADD
newColumn bit DEFAULT 0 NOT NULL
This works fine with SQL-server 7, but I get this error in 6.5:
'ALTER TABLE only allows columns to be added which can contain nulls. Column 'newColumn' cannot be added to table 'myTable' because it does not allow nulls.'
I also found this in the help files:
'Columns added to a table must be defined as NULL. When a column is added, the initial value for the column will be set to NULL. This restriction forces the ALTER TABLE statement to fail if the bit or timestamp datatypes are used.'
My question, is there any other way to do this on 6.5 ?

Hi @ all
I'm using MSSQL and PHP.
I've got the following sql statement:
$msquery = IF NOT EXISTS (SELECT SerienNr FROM tbl_Auftrag a WHERE a.SerienNr='PC8') INSERT INTO tbl_Auftrag (BMS_AuftragsNr, SerienNr, AuftraggNr, Zieltermin, Kd_Name) VALUES ('455476567','PC8','1','2006-3-2','Fritz')
The Statement itself works fine, but i've got a problem getting a return value whether the insert has succeed, or not. :confused:
mssql_query() always returns true if there occured no error in the statement. But i need to know if the insert procedded or not.
I tried:
$result = mssql_query($msquery);
$succeed = mssql_rows_affected ($result);
And:
$result = mssql_query($msquery);
$succeed = mssql_num_rows($result);
to get the rows, affected by the statement, but both return:
supplied argument is not a valid MS SQL-Link resource
Anyone an idea?

Im trying to select rows on the following criteria
My app has a user that can have x jobs, each job has related entries which are marked has unread or read. I need to return any jobs that contain any unread entries also I need to return other jobs that have no entries marked as read.
I am able to return the following:
Comment UnReadMy Job 164
Comment UnReadFor Cam 166
Comment ReadThe Job 157
Comment ReadThird 159
Comment ReadMy Job 164
On Site Visit ReadMy newest job for log test 167
but as you can see jobid 164 appears in both groups and I need it to be one or the other
I tried using the if exists statement and was only able to return one group either unread or read, not both. I've tried everything but I'm new and I figure that theres got to be a more elegant way. Heres my sql:

I'm trying to write a script that would only update a column if it exists.
This is what I tried first:
IF EXISTS (SELECT * FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME = 'Enrollment' AND COLUMN_NAME = 'nosuchfield')
BEGIN
UPDATE dbo.Enrollment SET nosuchfield='666'
END
And got the following error:
Server: Msg 207, Level 16, State 1, Line 1
Invalid column name 'nosuchfield'.
I'm curious why MS-SQL would do syntax checking in this case. I've used this type of check with ALTER TABLE ADD COLUMN commands before and it worked perfectly fine.
The only way I can think of to get around this is with:
IF EXISTS (SELECT * FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME = 'Enrollment' AND COLUMN_NAME = 'nosuchfield')
BEGIN
declare @sql nvarchar(100)
SET @sql = N'UPDATE dbo.Enrollment SET nosuchfield=''666'''
execute sp_executesql @sql
END
which looks a bit awkward. Is there a better way to accomplish this?

My client's website database is hosted by a third party. I need to alter one of the column definitions for the largest table in the database. Unfortunately, the transaction log fills up if I try to alter the table. I've done all the usual stuff like truncating the log, etc., but the simple fact is that the operation requires more log space than we have available. Therefore, we need to purchase additional disk space for the database.
What I'm looking for is a way to roughly estimate how much log space will be required to alter this table so that we purchase enough but not too much additional space. The table has an identity primary key and 4 other single column indexes: one int, one datetime and two varchar(30) columns.
Any suggestions? Thanks in advance.

I have coded an alter statement for adding a column to a temp table inside an sp,but it skips the alter statement while executing the sp! This happens even if I run the same code on query analyzer too. If I use 'GO' statement before the alter command,then it works fine on Query Analyzer.But, I can't use 'GO' in an sp. I am using the sa account. Any ideas on how to fix this??
Thanks.

Recently I created a DDL Server-scope trigger using the following:
create trigger stop_alter_database on all server
for ALTER_DATABASE
as
rollback;
print 'database change stopped by stop_alter_database';
go
Then I ran the following script:
alter database [test] modify file (name=test', maxsize=2028mb);
The result was:
Msg 3609, Level 16, State 2, Line 1
The transaction ended in the trigger. The batch has been aborted.
database change stopped by stop_alter_database
The problem is that when I checked the max size of the data file it had changed. So, the statement was never rolled back. Is there something I'm missing because I can't find any documentation or articles that state the inability to rollback alter database statements. Whats going on?

Hello all,
I am trying to add columns to several tables in a singular database. I want to check to see if the column exists in a given table first before executing the alter table command so that I can skip that command if the column already exists, and avoid aborting my script prematurely. I can't seem to find a way to check for the column's existance. Any suggestions?

I've some huge table (over 100GB each), these table contain column of NTEXT, IMAGE. Application team needs to change these data types to VARBINARY(MAX), I've tested the modification in our lab and I noticed that the operation has been almost immediate so, I think that DB Engnine has not converted the existing data in the column but it has simply changed the definition of the column.
Or maybe NTEXT and IMAGE can be transparently converted into VARBINARY(MAX)?
Anyway, I want to be sure that the modified table is "coherent" I don't want that at a given point SQL Server tells me that some data is not readable.

I have scenario where i have to pick one particular value from where condition. Here is the example:A store can have different types i-e A or B , A and B or either A or B.
Store   Type   Sales
11 Â Â Â Â Â A Â Â Â Â 1000
23 Â Â Â A Â Â Â 1980
23 Â Â Â B Â Â Â 50
5 Â Â Â Â B Â Â Â 560
I want to filter the store in "where clause" Â where
1)- if the store has type A and  B, then assign only A
2)- if the store has  type A associated with it then assign A
3)- if the store has type B associated with it, then assign B.
Select Store, sum(sales), Type
from table1
where (TYPE]= Â (case when [TYPE] in ('A','B') then 'A'
when [TYPE]='A' then 'A' else 'B'end))
GROUP BY [store], [TYPE]
The above statement is not working for when store has only Type B associated with it.

Hey gang,
I've got a query and I'm really not sure how to get what I need. I've got a unix datasource that I've setup a linked server for on my SQL database so I'm using Select * From OpenQuery(DataSource, 'Query')
I am able to select all of the records from the first two tables that I need. The problem I'm having is the last step. I need a field in the select statement that is going to be a simple yes or no based off of if a customer number is present in a different table. The table that I need to look into can have up to 99 instances of the customer number. It's a "Note" table that stores a string, the customer number and the sequence number of the note. Obviously I don't want to do a straight join and query because I don't want to get 99 duplicates records in the query I'm already pulling.
Here's my current Query this works fine:
Select *From OpenQuery(UnixData, 'Select CPAREC.CustomerNo, CPBASC_All.CustorCompName, CPAREC.DateAdded, CPAREC.Terms, CPAREC.CreditLimit, CPAREC.PowerNum
From CPAREC Inner Join CPBASC_All on CPAREC.CustomerNo = CPBASC_All.CustomerNo
Where DateAdded >= #12/01/07# and DateAdded <= #12/31/07#')
What I need to add is one more column to the results of this query that will let me know if the Customer number is found in a "Notes" table. This table has 3 fields CustomerNo, SequenceNo, Note.
I don't want to join and select on customer number as the customer number maybe repeated as much as 99 times in the Notes table. I just need to know if a single instance of the customer number was found in that table so I can set a column in my select statement as NotesExist (Yes or No)
Any advice would be greatly appreciated.

I am using the following code to insert records into a destination tablethat has a three column primary key i.e. (PupilID, TermID &SubjectGroup). The source table records all the pupils in a school with(amongst other things) a column (about 50) for each subject the pupilmight potentially sit. In these columns are recorded the study groupthat they belong to for those subjects. The destination table holds arecord per pupil per subject per term, against which the teacher willultimately record the pupils performance.The code as shown runs perfectly until the operator tries to insert aselection of records that include some that already exist. What I wouldlike it to do is, record those, which do not exist and discard theremainder. However, whenever a single duplicate occurs SQL rejects thewhole batch. I know that my solution will probably involve using the‘NOT EXISTS’ expression, but try as I might I cannot get it to work. Tofurther complicate things, the code is being run from within VBA usingthe RunSQL command.The variables ‘strFieldName’, ‘strGroup’ & ‘strTerm are declared at thestart of the procedure and originate from options selected on an Accessform.INSERT INTO dbo.yInterimReportData (PupilID, LastName, FirstName,TermID, SubjectGroup) SELECT PupilID, LastName, FirstName," & "'" &strTerm & "'" & "," & "'" & strGroup & "'" & "FROM dbo.Pupils WHERE (" &strFieldName & " = " & "'" & strGroup & "')Any Ideas?RegardsColin*** Sent via Developersdex http://www.developersdex.com ***
