I am dropping 60 out of 133 columns on a user table, but am finding that the spaceused by the table ( as shown by sysindexes.dpages ) is not being freed up.
I have dropped and recreated all indexes on the table, with no effect on the dpages value, as well as running dbcc updateusage for the table.
Is it not possible to free up the space used by using this method ?
Is recreating and repopulating the table with only the required columns the correct / only way to do this ?
I have a VIEW which is dynamically generated through complex dynamic SQL. Unfortunately the dynamic SQL uses "Select * from table" to select the columns because the programmer did that to reduce the amount of code in the dynamic SQL string as the code can't be debugged if it's too long.
Therefore, I have a VIEW with columns in it I don't need, and want to remove them from the view - I need to remove all columns with column names matching the syntax '%1%_2' .
The view is called TEMP_EXPORT_1
I can either use the code below to return a list of columns that I want removed:
select column_name from information_schema.columns
where table_name='TEMP_EXPORT_1' and column_name like '%1%_2'
Or I can use the code below to return the list of columns that I want to keep:
select column_name from information_schema.columns
where table_name='TEMP_EXPORT_1' and column_name not like '%1%_2'
Now how would I go about altering TEMP_EXPORT_1 view so that it no longer has these columns? I know views don't have a drop statement...
Therefore I tried the following but I'm not sure of the syntax:
ALTER VIEW dbo.TEMP_EXPORT_1 AS SELECT (select column_name from information_schema.columns where table_name='TEMP_EXPORT_1' and column_name not like '%1%_2') FROM dbo.TEMP_EXPORT_1
Am I on the right track? how can I ALTER this view to remove these columns? ... I want to keep this separate from the code that generated the view as I want it as an optional procedure that can be run if needed.
1. We have user defined type (Sql type = bit ) with rule setting it to 0 2. New column(isVIP) was created using this user defined type 3. sp_unbindrule was used to unbind rule from new column (isVIP) 4. Alter table Client drop Column isVIP !!!! (invalid syntax )
I need to run the alter table to drop a default. However, the default name is kind of 'dynamic' from around 1000 databases, thus I need to run the following sql to get the name to a variable. Now, it looks the alter table statement does not like to drop a vaiable, is there a solution about it?
declare @radius_default varchar(40) select @radius_default = (select sobj.name from sysobjects sobj inner join syscolumns scolumn on sobj.ID = scolumn.cdefault where scolumn.name = 'radius' and sobj.name like '%LandMarks%') print 'Need To Drop @radius_default: ' + @radius_default --==================================== alter table LandMarks drop constraint @radius_default
Hi: I need to change a column's datatype from tinyint to int as follows: alter table tableName alter column column1 int
but with error <<'DF__LandMarks__color__6A50C1DA' is depending on it.>>
However, this old default is not part of the constraint. Thus, the only way is to delete it from sysobjects.
unfortunately, the following code I have to commented since they could only be executed line by line, not within a begin...end block. --exec master.dbo.sp_configure 'allow updates', 1 --reconfigure with override --delete from sysobjects -- where name = 'DF__LandMarks__color__6A50C1DA' -- and type = 'D' --exec master.dbo.sp_configure 'allow updates', 0 --reconfigure with override
I need to update 10 server around 2500 databases with this change. I have looked INFORMATION_SCHEMA related views, but not found default related, maybe I missed something.
When the new month comes I want the table to alter the columns automatically instead of manual how we do it now. The new Month table should delete [02-2015] and replace it with [03-2015].
I am having problem when performing the alter table switch. Both tables are identical and have pk.
ALTER TABLE SWITCH statement failed. There is no identical index in source table 'LocalDeltanet.dbo.testresults' for the index 'PKIDX_testSummary' in target table 'LocalDeltanet.dbo.testresults_part' .

I have performed the function on other tables successfully, but this is the first that has an identity column involved. Is there anything special that needs to be done?
Hi I’m trying to alter a table and delete a column I get the following error. The object 'DF__Morningst__LastU__19EB91BA' is dependent on column 'LastUpdated'. ALTER TABLE DROP COLUMN LastUpdated failed because one or more objects access this column. I tried deleting the concerned constraint. But the next time I get the same error with a different constraint name. I want to find out if I can dynamically check the constraint name and delete it and then drop the column. Can anyone help.IF EXISTS(SELECT 1FROM sysobjects,syscolumnsWHERE sysobjects.id = syscolumns.idAND sysobjects.name = TablenameAND syscolumns.name = column name)BEGIN EXECUTE ('ALTER TABLE tablename DROP CONSTRAINT DF__SecurityM__DsegL__08C105B8')EXECUTE ('ALTER TABLE tablenameDrop column columnname)ENDGO
How can I pervert dropping the column in the table (probably some process doing that and I want to find it) ? I need to be able to modify but not alter / drop column .
I must change replication schema from: Publisher - SQL2000(8.0.2039), Disrtibuter/Subscriber - SQL2000 to: Publisher - SQL2000(8.0.2039)(The same server), Disrtibuter/Subscriber - SQL2005(9.0.2047)(new server)
I have removed all subscription, publications, distributer and publisher. So there should not be now any information about replication.
Now I want to make some changes with tables and i try to alter and drop columns on publisher database. But it wont do... I always receive messages that tables and fields are being used in replication:
ALTER TABLE Clients DROP COLUMN ABCCode Msg 4932, Level 16, State 1, Line 1 ALTER TABLE DROP COLUMN failed because 'ABCCode' is currently replicated.
I tried to use sp_MSunmarkreplinfo and sp_removedbreplication but it did not help. I also tried to drop column with sp_repldropcolumn but got this message: Invalid object name 'sysmergearticles'. Looks like server (publisher) still has information about old replication. But how to delete this information? And how can I alter and drop fields?
I am writing a procedure to drop a specific user's schema only. I select all his/her table name and foreign key in a temp table first and then use a cursor to get the table name and foreign key, and begin drop foreign keys and drop table. However, sql think it is wrong with the syntax like "alter @table_name". Does anyone have a clue, what is wrong with my syntax. Or someone know how to drop one specific user's schema only (Other user may have same table in the database, and you don't want to drop that.

Thought I should post in the newbie forum for a while, instead. :-)
I have a couple of scripts that I've generated that drop a couple of system stored procedures and recreate them. I'm not sure why I did it in the first place, but I think it was that it wouldn't let me run an ALTER statement on them. Specifically, I'm now looking at sp_add_operator. I changed it to a 500 character email field instead of whatever it was (100, I think.)
/* Explanation: Why did I do that? SQL Mail is prohibited here, so I'm using CDO_Sysmail to email myself and the developers if a job fails. The list of people to email is determined by the owner of the database, who is also an operator in SQL. I get the list of emails from the email field of the operator properties. Hence, I need a bigger email field. Yes, I now know it would most likely be better to create an ADMIN database on each server for this kind of stuff. (Thanks to Tara for that blogged suggestion.) */
While I will probably go back to the default stored procedure, this got me to thinking: when would it be better to use an ALTER statement on a SProc rather than to do a DROP and CREATE?
I need to know definitively when I need to drop and recreate column statistics (histogram) when altering a column. Empirically, it seems I can lengthen a varchar or change a not null column to a nullable one, and then existing statistics dont' cause
Msg 5074, Level 16, State 1, Line 1
The statistics 'c1' is dependent on column 'c1'.
Msg 4922, Level 16, State 9, Line 1
ALTER TABLE ALTER COLUMN c1 failed because one or more objects access this column.
But, if I change a column to not nullable or shorten a column, I get the error.
Is this the complete description of when I need to drop and recreate column statistics and when I don't?
Is there any way to remove the IDENTITY property of a column? I originally used it, but it caused so many headaches with ADO.NET that I've decided to just increment the darn things manually. So I want to turn it into just a normal integer column.
If there's no direct way, can someone suggest a quick way to create a new column, copy all the old values into the new column, change the primary key to the new column, and drop the old column?
We have a generic sql login "prduser". Applications use this login. We want the login NOT to have ALTER PROCEDURE and DROP PROCEDURE permissions only on the stored procedures(there are thousands of them).

I am trying to edit several tables that were imported in tab-delimited format from text files. I am trying to generate a script that will alter the data type for several different columns.
I have succesfully edited a single column with the following code: USE THCIC ALTER TABLE PudfTest ALTER COLUMN DISCHARGE VARCHAR(6) NULL
However, I have need to create a script that will change the data type for over 100 columns. So far, everything I've read tells me that multiple 'alter column' statements cannot be run in a single query. I'm hoping someone can shed some light on this, or at least point me in another direction so that I won't have to manually change the data type for every column in each of the tables.
I would like to alter view to add columns. My base table is populated by application and the base table name is always change. Is there any way to add some extra columns to this view.
One way is to create a sp to add columns and use the view inside the sp. But I would like to know is there any way to alter the view.
Hello,I tried to make what one reply advice to recover the disk space afterDROPed columns but it doesn't work. I did DBCC DBREINDEX to the tablebut nothing changes.Any other solution?Ignacio
In my DB, many of my tables have a column named upsize_ts I have already been told that it is not linked in any way with the data in the DB. The data type of these columns is timestamp and every record in those colum is this : "<Binary>" Now maybe it's because the whole DB comes from an export from an Access DB, or maybe not. I just had a few questions:
1/ Does anyone know why that column got generated and what it means? (optional) 2/Now the real question: is there any statement allowing me to "mass-drop" all those columns named "upsize_ts" in every table of my DB at the same time? Or at least any way not to do it one drop table at a time?
Hi guys, If I have a temporary table called #CTE With the columns [Account] [Name] [RowID Table Level] [RowID Data Level] and I need to change the column type for the columns: [RowID Table Level] [RowID Data Level] to integer, and set the column [RowID Table Level] as Identity (index) starting from 1, incrementing 1 each time. What will be the right syntax using SQL SERVER 2000?
I am trying to solve the question in the link below: http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=2093921&SiteID=1
Thanks in advance, Aldo.
I have tried the code below, but getting syntax error...
ALTER TABLE #CTE ALTER COLUMN [RowID Table Level] INT IDENTITY(1,1), [RowID Data Level] INT;
I have also tried:
ALTER TABLE #CTE MODIFY [RowID Table Level] INT IDENTITY(1,1), [RowID Data Level] INT;
For reasons that are not relevant (though I explain them below *), Iwant, for all my users whatever privelige level, an SP which createsand inserts into a temporary table and then another SP which reads anddrops the same temporary table.My users are not able to create dbo tables (eg dbo.tblTest), but arepermitted to create tables under their own user (eg MyUser.tblTest). Ihave found that I can achieve my aim by using code like this . . .SET @SQL = 'CREATE TABLE ' + @MyUserName + '.' + 'tblTest(tstIDDATETIME)'EXEC (@SQL)SET @SQL = 'INSERT INTO ' + @MyUserName + '.' + 'tblTest(tstID) VALUES(GETDATE())'EXEC (@SQL)This becomes exceptionally cumbersome for the complex INSERT & SELECTcode. I'm looking for a simpler way.Simplified down, I am looking for something like this . . .CREATE PROCEDURE dbo.TestInsert ASCREATE TABLE tblTest(tstID DATETIME)INSERT INTO tblTest(tstID) VALUES(GETDATE())GOCREATE PROCEDURE dbo.TestSelect ASSELECT * FROM tblTestDROP TABLE tblTestIn the above example, if the SPs are owned by dbo (as above), CREATETABLE & DROP TABLE use MyUser.tblTest while INSERT & SELECT usedbo.tblTest.If the SPs are owned by the user (eg MyUser.TestInsert), it workscorrectly (MyUser.tblTest is used throughout) but I would have to havea pair of SPs for each user.* I have MS Access ADP front end linked to a SQL Server database. Forreports with complex datasets, it times out. Therefore it suit mypurposes to create a temporary table first and then to open the reportbased on that temporary table.
So I have been trying to get mySQL query to work for a large database that I have. I have (lets say) two tables Table_One and Table_Two. Table_One has three columns: Type, Animal and TestID and Table_Two has 2 columns Test_Name and Test_ID. Example with values is below:
In Table_One all types come under one column and the values of all Types (Mammal, Fish, Bird, Reptile) come under another column (Animals). Table_One and Two can be linked by Test_ID
I am trying to create a table such as shown below:
This should be my final table. The approach I am currently using is to make multiple instances of Table_One and using joins to form this final table. So the column Bird, Reptile, Mammal and Fish all come from a different copy of Table_one.
For e.g
Select Test_Name AS 'Test_Name', Table_Bird.Animal AS 'Birds', Table_Mammal.Animal AS 'Mammal', Table_Reptile.Animal AS 'Reptile, Table_Fish.Animal AS 'Fish' From Table_One
[Code] .....
The problem with this query is it only works when all entries for Birds, Mammals, Reptiles and Fish have some value. If one field is empty as for Test_Two or Test_Three, it doesn't return that record. I used Or instead of And in the WHERE clause but that didn't work as well.
