Does anyone know if it is possible to create dynamically named tables from within a stored procedure? The goal is to append a unique identifier on the end of an otherwise static table name to allow for multiple incarnations of the table to exist concurrently while not interfering with each other. For example, we would like to create and use a temp table that is suffixed with a login name to or a timestamp to make it unique.
Is this possible?
I want to use a Make Table Query to generate a new read-only Table. This I can do but my problem is that I want to be able to name the new Table containing only the records from a calendar year; e.y. Rents2001 and the next year another new table would be created and called Rents2002 and next year Rents2003 ...............
I require the Table to be generated yearly. I know I could do this in other ways but I really require the Table as once I have it I will be doing other things with it to give the final report.
Any suggestions how I can generate the Table with the YEAR being in the Table Name as part of running the Make Table Query? Thanks
I have to build a table Physicalcharacterics in sql.
Convention for naming a table
Would I name this table in sql server
tbl_User_PhysicalCharacterics.
My main parent table is tbl_User.
Is that too long of a name.
We have two tables. Users and Projects and there is a many-to-many relationship.Ex. A user can be assigned into multiple projects.For the relationship table, should the table name be UserProjects or ProjectUsers?Also should it be singular or plural? (ex. UsersProjects or ProjectsUsers)?

I am trying to name a new SQL table, but I keep receiving a message that a table with this name already exists in the database. However, when I try to run a SELECT statement using that table, the error msg tells me the object does not exist,and it is not in the combobox of existing tables that can be added to a diagram.
Any clues would be appreciated, thanks !
I need to name make the name of a column the same as the name of a table from the result of a sql query.. here is the assignment question below..I can't figure out how to get the name of the table to be inputed as the column name..
Write a script that uses dynamic SQL to return a single column that represents the number of rows in the first table in the current database. The script should automatically choose the table that appears first alphabetically, and it should exclude tables named dtproperties and sysdiagrams. [highlight=#ffff11]Name the column CountOfTable, where Table is the chosen table name.[/highlight]
Hint: Use the sys.tables catalog view.
I can figure out the rest. and actually have alredy done it, but i cannot figure out how to do the part that is highlighted above. I looked at lots of things on google to figure it out but no luck..Can some just give me some directlon or an example..

Hello, I have 2 tables: Articles and Users. These 2 tables are related by AuthorId (FK) in Articles and UserId (PK) in Users. My question is: should the use the same name for the 2 keys, i.e., UserId? Or it is normal to use AuthorId in Articles table and UserId in Users table. This makes more sense. Just a naming question. Thanks, Miguel

I am storing the tables in a local variable called@TABLENAME VARCHAR(16)and when i say SELECT * FROM @TABLENAMEit is giving me an error and I think I cannot declare @TABLENAME as a table variable because I do not want to create a temp table of sorts.I hope I am clear.thanks,Murthy here

Hello, all. I'm attempting to insert data into a table variable using dynamic SQL created at runtime.
However, with a Table variable, SQL server will not allow the EXEC method to be used in an INSERT statement.
How do I go about this?

Is it possible to create a temp table using exec. e.g
exec('create table #temp1 (xyz int, abc int)')
when I run the above statement, I dont get an error but nothing happens.
The reason I need to create it dynamically is that in my stored proc, I am passed a number. This number determines how many columns my temp table should have.
thanks

Does TSQL limits us on creating temp table using dynamic sql? If so any workaround... Here's the sample code that doesn't let me run second exec because it looks like first exec is not able to create a temp table.
declare @str1 varchar(80),@str2 varchar(80)
set @str1='create table #tmp(col1 int)'
set @str2='insert into #tmp values (10)'
exec (@str1)
exec (@str2)
The following dynamic SQL script works for creating a table on the fly but if I change the select @tmpTblNm = 'tmpABC' to select @tmpTblNm = '#tmpABC'
it will not create the temp table. Can anyone help on creating a temp table dynamiclly?

@str varchar(1000)
select @tmpTblNm = 'tmpABC'
select @str = ''
-- Create a temp table to hold the current page of data
-- Add an ID column to track the current row
select @str = 'Create Table '+ @tmpTblNm +
' ( row_id int IDENTITY PRIMARY KEY,
customerID int,
customerName varchar(40),

city varchar(25) )'

I've got an update statement with a subquery (I'll post the code further down) that I need to either make dynamic or do something else to make sure it does what I want.
The query is as follows:-
UPDATE dbo.tbl_Process_List_Control_Table
SET LastUpdateDateTime = (
SELECT ISNULL(MAX([LatestRowUpdateDateTime]), @LastUpdateDateTime)
FROM [wtbl_Process_List_Patient]
)
WHERE ProcessList = @ProcessName
This is a called proc with the following parameters:-
@LastUpdateDateTime is the date of the last record to be loaded
@ProcessName is the name of the process that was started/finished.
I need to make [wtbl_Process_List_Patient] dynamic so it looks at a different table based on a passed parameter.I've tried making the whole thing dynamic but it states I need to declare @LastUpdateDateTime which I can't see how to do as it's already passed to the proc (as is the process name).
Hi all,
I have been attempting to construct some dynamic SQL using a table name as a parameter, and call it using sp_executesql, in SQL Server 2005.
According to all of the searches and articles I have read today, the following should work:
DECLARE @rownumINT
DECLARE @tabNamNVARCHAR(100)
DECLARE @SQLStringNVARCHAR(500)
DECLARE @ParmDefinition NVARCHAR(500)
SET @rownum = 35
SET @tabNam = 'AdminScriptHistory'
SELECT @SQLString = N'SELECT * FROM @table where executionorder=@row'
SET @ParmDefinition = N'@table VARCHAR(100), @row INT'
EXEC sp_executesql @SQLString, @ParmDefinition, @tabNam,@rownum
However, it fails with:
Msg 1087, Level 15, State 2, Line 1
Must declare the table variable "@table".
Anybody know why?
Cheers

I have an Oracle 10G database with some tables that I want to load into my SQL 2005 database every night (Datawarehouse). The tables may change(add columns) and this could be done in SQL 2000 DTS by writing a script as transformation. How can I do this in SSIS?

i have a dataset which returns me a dynamic set of data ie. number of columns can be different....say 14 columns for some dates...and just 12 for some other...(pivot table is being used in the backend)...how can i present this in the table...also my column names are best suited to be the column headers in the table.....is it possible to create a table at runtime...??
Hello all,
I have the following situation.
Our customer would like to generate a raw data export report from specific customer databases.
I have an administrative database with a customer table. In this customer table each customer has it's on specific
customerId guid.
Each customer also has it's own customer database that is named: Customer_ + guid of the customer in the admin
database (eg: Customer_982240e79f424fb0a1d4bed16267245d).
This customer database has 1 main table (dbo.Data), but the design can be different depending on the customer.
Our customer would like to have the possibility to select specific fields from the table to export to an excel file.
So i never know in advance how much fields there will be in the table.
What i want to achieve is to generate a report where i can select a specific customer from a list (from the admin database). Then be able to view all the available fields inside the table (like a dataset or something) and then let the
customer select which fields he wants in his data export report.
Can this be achieved in RS2005?

Hi,
I'm trying to import a csv file directly to my database every month. The contents of the file stays the same, however the format of the columns may vary. For example, 1 month I can have the following:
Time, Probe1, Probe2, Probe3, Probe4
Whereas the next month I can have something like this
Time, Probe2, Probe3, Probe1, Probe4
The "Time" column will always be on the left side, but the probes may vary in their placement.
I'm importing this csv to a temp table, where I then run a query to select any new data and enter that in my main tables. The problem is that when i import the csv, if the placement of the columns has changed, the data gets entered in the wrong locations.
Is there any way to create this temp table dynamically, based on what the header columns of the csv file are?
Any help appreciated!
I've got a DB2 database that contains a lot of tables. I need to extract the data from some of them and put them in a SQL Server database. The number of tables needed may change, so I need an easy way of controlling this.
So, I created a lookup table in the target SQL Server DB that lists the tables I want with any selection criteria needed.
I have a For Each loop that goes through every row in the table. using the current row, it deletes the contents of the destination table (done and working), and then tries to load the source into it.The destination OLE DB uses a variable for the table name to insert into.
The problem I've got is whilst I can set up the OLE DB Source to use a SQL command as variable, I have to do it in the advanced editor or in the properties, as the normal editor gives an OLE DB Error. This is probably due to the fact that the variable has nothing in it at this point. I've turned EvaluateExternalMetaData off to avoid any design time errors, but when attempting to run I still get :
Code Snippet
[DTS.Pipeline] Error: "output "OLE DB Source Output" (11)" contains no output columns. An asynchronous output must contain output columns.
Which I understand, as there are none until runtime. How do I get around this problem of not having any columns to map until I know which table I am processing?
Thx

I would like to partition a table having only items posted in the last 24 hours in one filegroup and all others in another. Is there a way that my partition function could contain something like "col1 >= dateadd(d,-1,getdate())" and have items move to the secondary filegroup as they age pst 24 hours?
Thanks
