TSQL Change The Position Of A Column?
Dec 16, 2004
We have a little app to help us move applications from developent --> stage --> production. It uploads the files, runs the new stored procedures etc.
One of the things it does is create new columns in existing tables. In EM you can create a new column in any position, but ALTER TABLE seems to only add columns to the end of the table. Is there a way in TSQL to create columns in arbitrary positions in the table? Or do I have to recreate the whole table?

1 have a table with 74 colun.But due to some deletion i have the ordinal postions as
1
2
3
.
.
69
70
72
73
74
76
what i wants is to change the ordinal from 72 to 71,73 to 72,74 to 73,76 to 74
SELECT @field = 0, @maxfield = max(ORDINAL_POSITION) FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME = @TableName
-- handle insert case here
SELECT @field = min(ORDINAL_POSITION) FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME = @TableName and ORDINAL_POSITION > @field
SELECT @bit = (@field - 1 )% 8 + 1
SELECT @bit = power(2,@bit - 1)
SELECT @char = ((@field - 1) / 8) + 1
--IF substring(COLUMNS_UPDATED(),@char, 1) & @bit > 0 or @Type in ('I','D')
IF substring(COLUMNS_UPDATED(),@char, 1) & @bit > 0 or @Type in ('D') -- For the insertion case don't save the iserted data.
I needed it as i have a trigger whihc is adding value in a log table on update but due to this problem it fails for certain column
Trgger is solme thing like
WHILE @field < @maxfield
BEGIN
SELECT @field = min(ORDINAL_POSITION) FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME = @TableName and ORDINAL_POSITION > @field
SELECT @bit = (@field - 1 )% 8 + 1
SELECT @bit = power(2,@bit - 1)
SELECT @char = ((@field - 1) / 8) + 1
--IF substring(COLUMNS_UPDATED(),@char, 1) & @bit > 0 or @Type in ('I','D')
IF substring(COLUMNS_UPDATED(),@char, 1) & @bit > 0 or @Type in ('D') -- For the insertion case don't save the iserted data.
BEGIN
IF @Type not in ('I')
BEGIN
SELECT @fieldname = COLUMN_NAME FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME = @TableName and ORDINAL_POSITION = @field -1
--print('fieldname = '+@fieldname)
SELECT @sql = 'insert Audit (ActionTypeID, RowID, TableName, PK, FieldName, OldValue, NewValue, UpdateDate,UserID, UserName, UserType)'
SELECT @sql = @sql + ' select convert(bigint,' + @ActionTypeID + ')'
SELECT @sql = @sql + ',' + @RowID
SELECT @sql = @sql + ',''' + @TableName + ''''
SELECT @sql = @sql + ',' + @PKSelect
SELECT @sql = @sql + ',''' + @fieldname + ''''
SELECT @sql = @sql + ',convert(varchar(1000),d.' + @fieldname + ')'
SELECT @sql = @sql + ',convert(varchar(1000),i.' + @fieldname + ')'
SELECT @sql = @sql + ',''' + @UpdateDate + ''''
SELECT @sql = @sql + ',' + @UserID
SELECT @sql = @sql + ',''' + @UserName + ''''
SELECT @sql = @sql + ',''' + @UserType + ''''
SELECT @sql = @sql + ' from #ins i full outer join #del d'
SELECT @sql = @sql + @PKCols
SELECT @sql = @sql + ' where i.' + @fieldname + ' <> d.' + @fieldname
SELECT @sql = @sql + ' or (i.' + @fieldname + ' is null and d.' + @fieldname + ' is not null)'

Hello,
I have a table with the column description. Lets imagine that I have the records:
"a"
"b"
"c"
If this was a List and I wanted to move the "c" to the first position, I would simply remove the "c" and insert it in the 0 index position.
How can I do this with sql ce?
I could create another column named position and every time I would want to change the position, I would increment every other positions below. Example, "c" goes to first position:
position - description
1 - "a"
2 - "b"
3 - "c"
->
1+1 - "a"
2+1 - "b"
1- "c"
->
1- "c"
2 - "a"
3- "b"
But if I have lets say 100 thousand rows and I want to move the last one to the first position I have to do the operation 100K times.
Is there a more effective way to do what I want?
Thank you,
ARtur

I want to Change parameter position in SSRS report.I need Start Date and End Date Parameter at same column so client can easily select Start Date and End Date.I have tried a lot but not succeed.
How Can I change the position of Start Date and End Date.I can't change order of other three parameter Select Institutions, Select Author and Course Pack Names parameter because they are internally related to each other(forward dependencies are there).

What is a good method/mechanism to swap the position of multiplecolumns?For instance, tblXZY has the followings columns and respectivepositions:tblXZY======xyzUUID 1fn 2ln 3phone 4email 5city 6state 7....Now, I need to make city as 2 and state as 3. BTW, the tblXYZ tablehas data there. Copy/select all the data into a new table withdesired column position would require constraints re-mapping etc.,which seems quite a bit hassle.Thanks.

Is there any way to select columns by ordinal position rather than by name?
Something like
Select t.[1] as col1, t.[2] as col2
FROM table t
The question comes because of a very specific situation where I've got 2 databases that have exactly the same schema at a column/datatype level but the column names are different. There are a few other ways to skin the cat but I'm interested if it can be done this way - without a join to syscolumns.

I have a Stacked Column graph and when we set the Position of the Point Label to be "Top Center", the Point Label always stays in the center of that particular Bar.
On a easier, basic Bar chart, the Point Label setting works correctly.
Has anyone else had a similar issue or know if this is a known issue ?

Hi
I am having a problem in auditing the column data in tables.My requirement is i have write a trigger which is capable of auditing the columns which are going to be added in the future also with out using dynamic SQL.is there any way to do so.
I feel if i can get the column data based on ordinal position then it is possible.
Can any body suggest.
My set Up is like this
I have a base_table to be audited.
I have a Audit_spec table which contains name of the table and columns to be audited.
And Audit table which actually captures the table name,column name ,old value and new value.
I have to audit only those columns in the Audit_spec spec.
If schema changes(Like new column added) happens to base_table and I want that column to be audited.with out any changes to my trigger code i should handle the newly added column ..

I have an application that controls user logins, passwords, etc. at the front end for a SQL database. I am in the stage of migrating to SQL2005 and cannot get the TSQL code to allow a user to change their own password. Here's the background;
The ADMIN of the app is a Sysadmin on the SQL server and can create logins, set roles, etc. Assume the Admin creates a user TOM with a password of xxxx. This works fine using the create login statement from a Connect.Execute statement from my app like so;
"Create Login 'TOM' With Password 'xxxx', Default_Database = 'myDB', Check_Policy = OFF"
TOM will be setup with db roles as well
When TOM logins into my app, he will have to change his password at some point. The TSQL code I am using (which fails) is executed by TOM who has a connection to the SQL db because he is logged into the app.
"Alter Login TOM With Password = 'xxxx' Old_Password = 'xxxxx', Check_Policy = OFF"
At this point I get an error:
RunTime error -2147217900 (80040e14)
ODBC SQL Server Driver][SQL Server] Cannot alter
the login 'TOM', becuase it does not exist or you do
not have permission.
Obviously it exists since TOM is currently logged into the SQL Server. So if it's permissions related, what permissions does a user need to change his/her password? Or is there another way to do it?
Thanks in advance for your help.

Hi guys,
If I have a temporary table called #CTE
With the columns
[Account]

[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:

I am looking for ways to add new column to a table with records inside. If I add the column using this statement:ALTER TABLE Table1 ADD NewColumn1 decimal(18, 2) NULLThe column would appear at the end.
Is there a way to set where the column should be placed? (Excluding dropping all columns and add the columns in sequence again). I know this might not be very important, I am interested in knowing how Enterprise Manager done this, since you can move a column up and down to change their sequence eventhough there're records inside.

I cannot manage to fetch the new timestamp value inside a TSQL Transaction. I have tried to Select "@LastChanged" before committing the transaction and after committing the transaction. A TimestampCheck variable is used to get the timestamp value of the Custom Business Object. It is checked against the row updating to see if they match. If they do, the Update begins as a Transaction. I send @LastChanged (timestamp) and an InputOutput param, But I also have the same problem sending in a dedicated timestamp param ("@NewLastChanged"): 1 select @TimestampCheck = LastChanged from ADD_Address where AddressId=@AddressId
2
3 if @TimestampCheck is null
4 begin
5 RAISERROR ('AddressId does not exist in ADD_Address: E002', 16, 1) -- AddressId does not exist.
6 return -1
7 end
8 else if @TimestampCheck <> @LastChanged
9 begin
10 RAISERROR ('Timestamps do not match up, the record has been changed: E003', 16, 1)
11 return -1
12 end
13
14
15 Begin Tran Address
16
17 Update ADD_Address
18 set StreetNumber= @StreetNumber, AddressLine1=@AddressLine1, StreetTypeId=@StreetTypeId, AddressLine2=@AddressLine2, AddressLine3=@AddressLine3, CityId=@CityId, StateProvidenceId=@StateProvidenceId, ZipCode=@ZipCode, CreateId=@CreateId, CreateDate=@CreateDate
19 where AddressId= @AddressId
20
21 select @error_code = @@ERROR, @AddressId= scope_identity()
22
23 if @error_code = 0
24 begin
25 commit tran Address
26
27 select @LastChanged = LastChanged
28 from ADD_Address
29 where AddressId = @AddressId
30
31 if @LastChanged is null
32 begin
33 RAISERROR ('LastChanged has returned null in ADD_Address: E004', 16, 1)
34 return -1
35 end
36 if @LastChanged = @TimestampCheck
37 begin
38 RAISERROR ('LastChanged original value has not changed in ADD_Address: E005', 16, 1)
39 return -1
40 end
41 return 0I do not have this problem if I do not use a TSQL Transaction. Is there a way to capture the new timestamp inside a Transaction, or have I missed something?Thank you,jspurlin

I have Two Database that exist on Two seperate servers. The two database contain same schema and contains tables and columns of same name. Some tables have slight differences in terms of data types or Data type lenght.
For example if a Table on ServerA has a column named - CustomerSale with Varchar (100, Null) and a table on ServerB has a column named CustomerSale with Varchar (60, Null), how can i find if other columns have similar differences in all tables with the same name and columns in the two servers.
I am using SQL Server 2005. And the Two Servers are Linked Servers
What Script can i use to accomplish this task. Thanks

I have two tables namely lu_parameter and tbl_param_values. The lu_parameter table consists of param_id and parameter column containing id numbers for the parameter names.
The tbl_param_values table consists of values corresponding to the parameters with the param_id value as the column header.
I want to join these two tables so that in the result query instead of param_id value as column heading, I need to have the parameter value as the column heading.
I have attached the screenshot of the data for reference. I am not that much aware of sql queries.

Hi
I am using one Publisher with many subscribers for Merge replication of a database.
I wanted to change size one column in a table. So I added a dummy column (through Filter column).
Copied data, dropped old column (through Filter column), added new column, copied data, and dropped dummy column.
On subscriber A, replication is OK. On subscriber B, I get the following message.
--------------------
Initializing
Connecting to Publisher 'REPLIC'
Retrieving publication information
Retrieving subscription information
A column was added to or dropped from the replicated table.
The schema script 'exec sp_repladdcolumn '[dbo].[Items]','C1',[NVARCHAR(1000) NULL], '%', 1' could not be propagated to the subscriber.
The schema script 'exec sp_repladdcolumn '[dbo].[Items]','C1',[NVARCHAR(1000) NULL], '%', 1' could not be propagated to the subscriber.
A column was added to or dropped from the replicated table.
--------------------
I made a new snapshot, reintialized subscription with upload, and tried to sychronize again.
But same message.
Question 1. Is there anyway to make replication?
Question 2. If not, can I at least upload data changes before dropping and making new publication?
