create a table using the value of a variable
example:
create uspCreateTable
@ NameTable varchar (10)
the
begin
create table @ NameTable (
id int,
Name varchar (20))
end
the intention is to create a procedure that creates tables changing only the name.
which is more efficient...which takes less memory...how is the memory allocation done for both the types.
View 1 Replies View RelatedAs part of my package, i require a date (Only date, not DateTime) which is 10 months previous to get date.Eg: for today if the package executes, then i want 12/1/2014 , which i will use in my package as a filter like 'where date='?' where ? is a paramter which is is derived from the above logic
So, I have a project parameter @ppdate with value as  -10. I create a variable with DateTime (because there is NO date type for SSIS) and gives the expression as below
dateadd("Month",@ppdate, DATEADD("D",-(DAY(GETDATE()))+1,GETDATE())) , I am getting '7/1/2011 11:33:38 AM' which i don't want - i want only '12/1/2014'. How can i get it?
To get '12/01/2014', Â If i change the variable from DateTime to string, then i think i cant use the value in the filter condition like ''where date='?' because this does not accept string. Is this correct?
I am writing a stored procedure and have a query where I create a variable from other table

Where Semester=@Sem
And Decision1=@Decision
But I am getting error for Decision1 , Decision2. How can I do that.

I am passing a variable to a stored procedure using
db.ExecuteNonQuery("dbo.CreateTable", @symbol); < C# CODE >
the variable shows up fine but the stored procedure does not create the table...
I have tried everything... here are two versions of code that do not work...
using Dynamic Sql....
CREATE PROCEDURE dbo.CreateTable
@symbol nvarchar(10)
AS
DECLARE @Sql varchar
SELECT @SQL = 'Create Table [dbo].['+ @symbol +'](Symbol float'
SELECT @SQL = @SQL + '
, [Date] datetime
, [Open] float
, High float
, [Low] float
, [Close] float
, Volume integer)'
EXEC (@SQL)
this does nothing
And this one...(the longer version)
CREATE PROCEDURE dbo.CreateTable
(
@Symbol as varchar (10)
)
AS
DECLARE @SQL varchar(2000)
SET @SQL = "if exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[@Symbol]') and OBJECTPROPERTY(id, N'IsUserTable') = 1)
drop table [dbo].[@Symbol]
CREATE TABLE [dbo].[" + @Symbol + "] (
[Ticker] [varchar](10) Null,
[Date] [date] Null,
[Open] [float] NULL ,
[High] [float] NULL ,
[Low] [float] NOT NULL ,
[Close] [float] NULL ,
[Volume] [float] NULL ,
) ON [PRIMARY]"
EXEC(@SQL)
GIVES ME A 'The identifier that starts with... is too long, maximum length is 128'
This should be simple, but...
I want to create a table in a stored proc using a variable name instead of something hard coded. I was hoping to do something like....
CREATE PROCEDURE foo
-- Add the parameters for the stored procedure here
@TableName char = null
AS
BEGIN
SET NOCOUNT ON;
CREATE TABLE @TableName (
[HRMONTH] [int] NULL,
[HRYEAR] [int] NULL
) ON [PRIMARY]
But no combination of names '@'s, etc, allows me to use a variable name that I passed into the procedure. What am I missing? I will either receive a syntax error or the procedure will create a table called TableName rather than whatever TableName really stands for...
Thanks,
Tom
I am trying to use a stored procedure to update a column in a sql table using the value from a variable table I getting errors because my syntax is not correct. I think table aliases are not allowed in UPDATE statements.
This is my statement:
UPDATE [dbo].[sessions_teams] stc
SET stc.[Talks] = fmt.found_talks_type
FROM @Find_Missing_Talks fmt
WHERE stc.sessionid IN (SELECT sessionid FROM @Find_Missing_Talks)
AND stc.coupleid IN (SELECT coupleid FROM @Find_Missing_Talks)
Can someone send me an example of creating a variable to use instead of a temp table? I cannot find an example on books on line, but know it is possible in SQL2000.
Thanks,

Is it possible to have part of a table name used in a CREATE statementcontained in a variable? Here's what I'd like to do, althoughobviously the syntax of this isn't quite right or I wouldn't be hereasking:DECLARE @TblPrefix char (3)SET @TblPrefix = 'tst'CREATE TABLE @TblPrefix + TestTable (col1 int)The point there is to have a table named tstTestTableThe reason I need to do this is that my ISP will only give me onedatabase to work with and I'd like to have two copies of theapplication I'm developing running at the same time. So I'd like torun the sql script that creates the tables with TblPrefix set to "dev"and then run it again with TblPrefix set to "liv"thankseric

Hi
I need to create a Table using the SQL Task and a Variable as the Table Name
I am getting an Error: "Syntax error or access violation". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly.
The SQL Statement that I am using is
Create Table ? (ColumnA char(5) Null)
The ? is the Value of the Variables
Is there a way of doing this

Greetings!I am now doing one type of analysis every month, and wanted to creattable names in a more efficient way.Here is what happens now, everytime I do the analysis, I will create atable called something like customer_20050930, and then update thetable by using several update steps. Then next month I will create atable called customer_20051031. Does anyone know if there is a betterway to do it? like using a macro variable for the month-end date? Noweverytime I have to change the table name in every single update step,which would cause errors if I forget to change one of them. By using amacro, I would only need to change it once.Thanks!

i am inserting something into the temp table even without creating it before. But this does not give any compilation error. Only when I want to execute the stored procedure I get the error message that there is an invalid temp table. Should this not result in a compilation error rather during the execution time.?
--create the procedure and insert into the temp table without creating it.
--no compilation error.
CREATE PROC testTemp

BEGIN
INSERT INTO #tmp(dt)
SELECT GETDATE()
END
only on calling the proc does this give an execution error

I'm trying to create a table in Microsoft Server Management Studio 2012. The table has two fields which are both foreign keys.
I created the following:
create table tblRoomEquipment(
RoomID nvarchar(8),
EquipmentType nvarchar(1),
foreign key (RoomID) references tblRoom(ID),
foreign key (EquipmentType) references tblEquipment(Type)
)
Both tblRoom and tblEquipment have the red line error which when I highlight say the they both reference an invalid table!
Both tables are there and have primary keys defined as ID & Type. I have searched around and all I could find was that there maybe a permission problem.
How to create insert statements of the data from a table for top 'n' rows. I know we can create using generate scripts wizard, but we can't customize the number of rows. In my scenario i got a database with 10 tables where every table got millions of records, but the requirement is to sample out only top 10000 records from each table.
I am planning to generate table CREATE statements from GENERATE Scripts wizard and add this INSERT STATEMENT at the bottom.
EX : INSERT [dbo].[table] ([SERIALID], [BATCHID] VALUES (126751, '9100278GC4PM1', )
Table ATable B
AIDBID
Col 1BCol1
Col 2
Col3
I want to put a check constraint on A.col3 that depends on the values of A.Col1, A.Col2 and B.BCol1
How can I achieve this without using function.
I am trying to create a table that would represent a workload for each shop. In order to do that I need to have WorkLoad table and ShopWorkLoad table which is actually just aggregation of WorkLoad.
WorkLoad contains a list of following items:
current orders that are in the process (one select statement)
scheduled orders (another select statement)
expected orders (third select statement) that come through a third-party system
All of this needs to be live. So, for example, as soon as order is added to Order table it should be included in WorkLoad if certain conditions are met. Same goes for scheduled orders (which come from another table). Expected orders will be loaded on a daily bases (based on historical data).
ShopWorkLoad table is aggregation of WorkLoad table.
Currently I did it this way:
Added after insert/update trigger on Order table: when order is created/updated, if it meets certain conditions, it should be inserted in WorkLoad, otherwise remove it from workload if it's in there and doesn't meet conditions
Added after insert/update trigger on Schedule table: when order is scheduled, if it meets certain conditions, it should be inserted in WorkLoad, otherwise remove it from workload if it's in there and doesn't meet conditions
Running daily job that populates WorkLoad table with expected orders based on historical values
Final step is to create an indexed view vShopWorkLoad
My biggest concern is usage of triggers which call pretty complex logic to determine whether item should be added to workload or not.
One other option was to create vWorkLoad view and somehow make it an indexed view but currently I don't see a way of doing that because the query consists of 4 union select statements, below is pseudo example. But even if doing it that way, how to build aggregated indexed view on top of vWorkLoad indexed view?
Third option is to use sql agent job which would run every x seconds (maybe 20) and it would execute all of these queries to populate WorkLoad table with delay of 10-20 seconds, but I am still not sure if this is acceptable to the client.
Fourth option is to create 3 or 4 indexed view where sum of them makes a workload. Then, ShopWorkLoad view would be built on top of these 3 or 4 indexed views, but in this case I don't know how this would affect performance since ShopWorkLoad query would be often queried.
Example of workload pseudo query:
select
WorkLoadType = 'Order in process',
OrderId,
ShopId,
...
from
Order
