Mass Table Structure Change For Column Order
Feb 26, 2008
Say you have an existing populated SQL 2005 database, with 700+ tables, and you want to just change the order of the columns inside every table. Short of manually building conversion scripts, anyone know an automated way to do this? I was thinking thru ways to do them all in one shot, and have tools like Erwin and DbGhost that could be used also. Basically moving some standard audit columns from the end of the tables to just after the PK columns.
Thanks, Bruce

I have a simple query which is taking about 2.5 minutes to execute. What can be done to speed it up ? I cannot change the table structure. even without the group by, and without the float and division, it takes about 2.25 minutes.
Select 'SV00302' as FileSource,
[Service_Call_ID],
sum(0) as ActualHours,
sum(cast([Estimate_Hours] as float)/100) as EstHours,
max(MODIFDT+Modified_Time) as ModifiedDateTime
[code]...

Hello,I have created the following trigger:CREATE TRIGGER tr_UDFTest ON UserDefinedFields FOR INSERT, UPDATEASDECLARE @foobar varchar(100)SELECT @foobar= foobar FROM insertedIF ( @foobar = 'foobar') INSERT INTO LogTable (LogText) values ('Found foobar')ELSE INSERT INTO LogTable (LogText) values ('Did not find foobar')GOBasically, the trigger monitors the values begin put in the foobar field,and acts accordingly based on what it finds. In practice, my needs are abit more complex (the trigger will be programmatically generated, based ona set of rules) but the principle is much the same.ErrorTable is defined as :create table LogTable (LogText varchar(128))UserDefinedFields is a table whose definition may change depending on theuser's needs, but for now assume it contains a varchar column calledfoobar.My problem is that if the user's needs change, and they remove the fieldfoobar, the trigger causes all subsequent inserts/updates to fail with anerror indicating the column foobar doesn't exist. (Which makes sense ofcourse!)CREATE TRIGGER tr_UDFTest ON UserDefinedFields FOR INSERT, UPDATEASDECLARE @foobar varchar(100)if not exists (select * from syscolumns sc inner join sysobjects so on sc.id = so.idwhere sc.name = 'foobar'and so.name = 'UserDefinedFields') BEGININSERT INTO LogTable (LogText) values ('Error : Foobar column does not exist!')RETURNENDSELECT @foobar= foobar FROM insertedIF ( @foobar = 'foobar') INSERT INTO LogTable (LogText) values ('Found foobar')ELSE INSERT INTO LogTable (LogText) values ('Did not find foobar')GOI'd be happy with the above 'flavor' of solution (bailing, or logging anerror and bailing, when we hit unexpected problems) as long as theinserts/updates don't fail otherwise. Perhaps I can nest a transaction, orsupress a RAISEERROR or something?The cleanest solution would probably be to change a bunch of clientsoftware such that it won't remove the foobar field if this field isneeded for a trigger (foreign key constraints based on the set of rulesI'm using are a nice and intuitive solution). Unfortunately, that doesn'twork well with my timeframe (done by thursday) as changing the clientsoftware is impossible by then. Any ideas or suggestions? Platform isWin2k, SQL 2000 Enterprise (I think enterprise, certainly 2000).thanks,Dave

I have set up mirroring in high availability mode (principal, mirror, and witness).
After setting up mirroring, I needed to adjust the size of a column in one of my tables. I did so with the following command
ALTER TABLE OrderOptimizer.dbo.rCodes ALTER COLUMN CodeDescription VARCHAR(8000).
The column was initially VARCHAR(128)
When I look at the table structure it shows that the column is now VARCHAR(8000), however I can only enter 128 characters into the field.
I forced a failover to look at the table on the mirrored version. It too showed that the column was VARCHAR(8000).
If I open the table I can enter more than 128 characters into the field, however when I refresh, it is truncated to 128 characters,
Any help would be appreciated

Hi, all experts here,
I am a bit confused for the model evaluation (lift chart), should we map all the columns for both the mining structure and the case table? I mean for those predictive models, we have a predict column, shouldnt we ignore the mapping of the predictive column between the mining structure and the case table? But it seemes we are not allowed to miss the predictive column mapping between the mining structure and the case table.
Why is that? Could any experts here give me some explanation on that?
Hope my question is clear for your help.
Thanks a lot and I am looking forward to hearing from you shortly.
With best regards,
Yours sincerely,

This subject has been posted several times, but I haven't seen a goodanswer.Problem:I want to change the order of the columns in a table using T-SQL only.Explanation:After running your code, I want to see the following table...CREATE TABLE [dbo].[TableName] ([First_Column] [int] NULL ,[Second_Column] [varchar] (20) NULL) ON [PRIMARY]look like this...CREATE TABLE [dbo].[TableName] ([Second_Column] [varchar] (20) NULL ,[First_Column] [int] NULL) ON [PRIMARY]Limitations:Don't post if your post would fall in the following categories:1. If you don't think it can be done2. If you think Enterprise Manager is the only way to do this3. If you think I should just change the order of my Selectstatements4. If you want to state that order column doesn't matter in arelational database5. If you want to ask me why I want to do thisWish:Hopefully the answer WON'T involve creating a brand new table, movingthe data from old to new, dropping the old table, then renaming thenew table to the old name. Yes, I can do that. The table I'm workingwith is extremely huge -- I don't want to do the data juggling.Thanks in advance!

I have two tables, one is called (questions), the second one (answers).
questions columns are (ID,questionTitle)
answers columns are (ID,questionID,answer, answerDate)
I use this query to load data: "SELECT q.questionTitle,COUNT (a.ID),a.answerDate FROM questions q LEFT JOIN answers a ON q.ID=a.questionID" the query is easy, but my problem which I can't solve is how can I fetch the data ordered by the column answerDate, I mean I want the first record to be the one which has the most recent answer and so on.

I have an existing SQL table that I want to import 300,000 rows into. I have copied the table headers into Excel and added all the rows but constantly getting multiple errors no matter what way I try to import it.
So far tried Import Method from SQL Management Studio, BULK INSERT and SQL Script. What is the easiest way?
If I try this
select *
into Coupon FROM OPENROWSET('Microsoft.Jet.OLEDB.4.0',
'Excel 8.0;Database=D:coupon.xls;HDR=YES',
'SELECT * FROM [coupon$]')
I get
OLE DB provider 'Microsoft.Jet.OLEDB.4.0' cannot be used for distributed queries because the provider is configured to run in single-threaded apartment mode.

Does column order matter when creating a table? For example, Should NOT NULL columns always come before NULL columns? Should most frequently used columns always be near the top? What about text, ntext and image data types? Should they always appear near the end of the column order?

I have a database (MSSQL). To demonstrate the problem let me show a fictive Tablestructure. I don't want to discuss about how to save the data differntly, because the structure is fix and I can't change it.To get this result I would do a sql query with a lot of joins like that:
SELECT firstname, lastname, email.value, phone.value
FROM Customer
INNER JOIN
(
SELECT Customer_Properties.id, Customer_Properties.value
FROM Customer_Properties
[code]...
I don't think that this is really performant and the SQL-Queries get very complicated. Give it a other methode for that? I can't change the data structure.

I know we could change the data type or width of a table column in SQl 7 database, but I am not certain if this column is a primary key. Can we change a primary key column width? If we can, how about this column as a foreign key in another table? Will it be automatically updated to the same width? Thanks in advance for your input.

Hello all,I'm using SS2K on W2k.I'v got a table say, humm, "Orders" with two fields in the PK:OrderDate and CustomerID. I would like to add an "ID" column whichwould be auto-increment (and would be the new PK). But, I would reallylike to have orders with the oldest OrderDate having the smallest IDnumber and, for a same OrderDate, I'd to have the smallest CustomerIDfirst. So my question is:How could I add an auto-increment column to a table and make it createits values in a particular order (sort by OrderDate then CustomerIDhere)?In the real situation, the table I want to modify has around 500krecords and the PK has 5 fields and I want to sort on three of them.Thanks for you helpYannick

I was just messing around with some ad hoc views and table returningUDFs today so I could look at and print out data from a small tableand noticed something strange.If I stick my select statement into a View the columns are returned inthe order I specify in the SELECT, but if the same statement is in a UDF(so I can specify a parameter), the columns are not returned in theorder specified in statement.I know that relations don't have a specified column order, but it was myunderstanding that a SELECT statement could be used to define how youwant your data presented. Views seem to respect the order specified inthe SELECT, but functions don't.What am I missing? Is there some way to force the order of the columnsreturned from a SELECT?View:CREATE VIEW dbo.View1ASSELECT Ident, Text, Type, ParentStmt, ForStmt, IfStmt, ChildStmt,ThenStmt, ElseStmt, NextStmtFROM dbo.tblStmtWHERE (Ident LIKE '4.2.%')Column order from this view:Ident, Text, Type, ParentStmt, ForStmt, IfStmt, ChildStmt, ThenStmt,ElseStmt, NextStmtFunction:ALTER FUNCTION dbo.Function1(@SearchPrm varchar(255))RETURNS TABLEASRETURN ( SELECT Ident, Text, Type, ParentStmt, ForStmt, IfStmt,ChildStmt, ThenStmt, ElseStmt, NextStmtFROM dbo.tblStmtWHERE (Ident LIKE @SearchPrm) )Column order from this function:Type, Text, ElseStmt, NextStmt, IfStmt, ChildStmt, ThenStmt, Ident,ParentStmt, ForStmtTable:(I know that this table isn't entirely normalized, but it serves mypurposes to have a matrix instead of a fully normalized relation):CREATE TABLE dbo.tblStmt (StmtID INT IDENTITY(1,1) CONSTRAINT PK_Stmt PRIMARY KEY,Ident VARCHAR(255),Text TEXT,ErrorText TEXT,Type INT,ParentStmt VARCHAR(255),ChildStmt VARCHAR(255),IfStmt VARCHAR(255),ForStmt VARCHAR(255),ThenStmt VARCHAR(255),ElseStmt VARCHAR(255),NextStmt VARCHAR(255),FullName VARCHAR(255),LocalName VARCHAR(255),Method INT)INSERT INTO tblStmt Ident, Text, Type, ParentStmt, NextStmtVALUES('4.2.1', 'LineNumberOfResp := EMPTY' 64, '4.2', '4.2.2')INSERT INTO tblStmt Ident, Text, Type, ParentStmt, ChildStmt, ForStmt,NextStmtVALUES('4.2.2', 'FOR K:= 1 TO 2', 128, '4.2', '4.2.3','4.2.7')INSERT INTO tblStmt Ident, Text, Type ParentStmt, ChildStmt, ForStmt,NextStmtVALUES('4.2.3', 'Person[K].KEEP', 16, '4.2', '4.2.3.1', '4.2.2', '4.2.4')INSERT INTO tblStmt Ident, Text, Type, ParentStmt, NextStmtVALUES('4.2.3.1' 'AuxInterviewerName := DOSENV', 64, '4.2.3', '4.2.3.2')

I have two tables:
dtr
dataid........Subtype
data
docid....mimetype
I need to change the value of column mimetype in table data, but only for these entries which have the value 144 in column "Subtype" in table dtr.
Here is my sql:
with cte as (
select
DataID,
SubType,
MimeType
from dtr A1, data A2
where A1.dataid=A2.Docid And A1.Subtype='144'
AND
A2.mimetype='application/news-message-id'
)
update cte set MimeType = 'application/x-outlook-msg'
I've tested it and it works. Do you see any problems with this SQL?
As updates are risky I'll do a database backup. Is it possible to get all changed entries so that I can track my update, because I don't have a report about the changes? Maybe that everythin is transferred to an output file?
