Need Help Creating A Temporary Table In MS SQL Server.

Oct 18, 2006

Hello,

I am working on a webapp using VB.net

Right now I am writing to a sql table during a process where the end user
starts entering the contents for a file that is going to be generated once he
finishes entering the data, but the problem is that if more than one user is
doing the same process the data would get mixed up.  To avoid this I
thought in creating a temporary table (its name will consist of a string
and the current date time). 

 I would like to see any tutorial
about creating and working with temp tables.  Or if you have any
suggestions, I will appreciate them.  Thanks

Problem While Creating Index For Temporary Table...

Sep 27, 2007



Hi,

i have created index for a temporary table and this script should used by multiusers.So when second user connecting to it is giving index i mean object already exists.

So what i need is when the second user connected the script should create one more index on temporary table.Will sql server provide any random way of creating indexes if the index exists already with that name??

Thank You,

SQL Server 2008 :: Creating Primary Key On Temporary Table?

Apr 30, 2015

Environment: Microsoft SQL Server Standard Edition (64-bit), 10.0.5520.0

I was doing a code review for another developer and came across this code:

CREATE TABLE dbo.#ABC
(
ReportRunTime DATETIME
,SourceID VARCHAR(3)
,VisitID VARCHAR(30)
,BaseID VARCHAR(25)

[Code] ....

This EXECUTES with no error or warning message.However, if I change this to CREATE the PK in an ALTER TABLE statement, I get the (expected by me) error:

CREATE TABLE dbo.#ABC
(
ReportRunTime DATETIME
,SourceID VARCHAR(3)
,VisitID VARCHAR(30)
,BaseID VARCHAR(25)
,OccurrenceSeqID INT

[code]...

==> Msg 8111, Level 16, State 1, Line 17 Cannot define PRIMARY KEY constraint on nullable column in table '#ABC'.

==> Msg 1750, Level 16, State 0, Line 17 Could not create constraint. See previous errors.

(note: As the #ABC table is an actual copy of a few of the columns in a "permanent" table, I will likely change the definition as follows such that the columns are defined to match the names / datatypes / NULLability:

SELECT TOP 0
CAST('01-01-1980' AS DATETIME) AS [ReportRunTime]
,SourceID
,VisitID
,BaseID
,OccurrenceSeqID

[Code] .....

Table Names In Stored Procedures As String Variables And Temporary Table Question

Apr 10, 2008

How do I use table names stored in variables in stored procedures?




Code Snippetif (select count(*) from @tablename) = 0 or (select count(*) from @tablename) = 1000000





I receive the error 'must declare table variable '@tablename''

I've looked into table variables and they are not what I would require to accomplish what is needed.
After browsing through the forums I believe I need to use dynamic sql particuarly involving sp_executesql. However, I am pretty new at sql and do not really understand how to use this and receive an output parameter from it(msdn kind of confuses me too). I am tryin got receive an integer count of the records from a certain table which can change to anything depending on what the user requires.




Code Snippet

if exists(Select * from sysobjects where name = @temptablename)
drop table @temptablename




It does not like the 'drop table @temptablename' part here. This probably wouldn't be an issue if I could get temporary tables to work, however when I use temporary tables i get invalid object '#temptable'.

Heres what the stored procedure does.
I duplicate a table that is going to be modified by using 'select into temptable'
I add the records required using 'Insert into temptable(Columns) Select(Columns)f rom TableA'
then I truncate the original table that is being modified and insert the temporary table into the original.

Heres the actual SQL query that produces the temporary table error.




Code Snippet
Select * into #temptableabcd from TableA

Insert into #temptableabcd(ColumnA, ColumnB,Field_01, Field_02)
SELECT ColumnA, ColumnB, Sum(ABC_01) as 'Field_01', Sum(ABC_02) as 'Field_02',
FROM TableB
where ColumnB = 003860
Group By ColumnA, ColumnB

TRUNCATE TABLE TableA

Insert into TableA(ColumnA, ColumnB,Field_01, Field_02)
Select ColumnA, ColumnB, Sum(Field_01) as 'Field_01', Sum('Field_02) as 'Field_02',
From #temptableabcd
Group by ColumnA, ColumnB




The above coding produces

Msg 208, Level 16, State 0, Line 1

Invalid object name '#temptableabcd'.

Why does this seem to work when I use an actual table? With an actual table the SQL runs smoothly, however that creates the table names as a variable problem from above. Is there certain limitation with temporary tables in stored procedures? How would I get the temporary table to work in this case if possible?

Thanks for the help.

Temporary Table Vs. Table Valued Function

Jun 6, 2006

I need to return a table of values calculated from other tables. I have about 10 reports which will use approx. 6 different table structures.

Would it be better performance wise to create a physical table in the database to update while calculating using an identity field to id the stored procedure call, return the data and delete the records. For Example:

StrVal1,Strval2,StrVal4,IntVal1,IntVal2,FloatVal1...

Or using a table-valued function to return a temp table as the result.

I just dont know which overhead is worst, creating a table per function call, or using a defined table then deleting the result set per sp call.

Creating Table Fields Dynamically From Another Table Row

Aug 31, 2006

Hello all:

Is it possible to creates fields of the table dynamically?. I have this situation in my project. This is just a small sample. I have row of length 140. I don't wan't to declare all this fields manually using the create table command.

The description of table is as, in this table all the field are of type varchar only, there are like 140 columns.

create dummy emp (
field1 VARCHAR(100), field2 varchar(200), field3 VARCHAR(100).... )

Table: Dummy
================================================== ==
field1 field2 field3..........
Empid Empname empaage1 sam 23...........
2 rai 22............
.
.
.
n raj 45.............
================================================== ==
Now I want to create another table as "EMP" , with proper data type
fields too..

create table emp (
empid int, empname varchar(100), empage int....)

The table should look like as:

Table: EMP
================================================== ==
Empid Empname empaage............
1 sam 23...............
2 rai 22................
.
.
.
n raj 45.................
================================================== ==

I want to do this dynamically.....
Some how I need to extract those field from table[dummy]; the first row acts as a column header for the table[Emp] and the subsequent row acts as a record for the table[Emp]

A small rough snippet of the code will be appreciated....

Waiting for replies........

Creating A Dimension Table From A 3-key Table

Jan 13, 2005

Hi All,

I have a situation with a table that was created for a transactional

system with a 3 columns key. The table is similar to the following:

countrystatecitydescription
11221City A from country 1 and state 12
11321City A from country 1 and state 13
21422City B from country 2 and state 14
21522City B from country 2 and state 15


Now I'm trying to create a dts package that would allow me to build a

city dimension table with unique codes (keys) for each city. What kind of

transformation should I use to translate the old codes (based on the

country-state-city key) into the new ones and preserving the data

integrity?

Thanks,

Ignacio

Temporary Table

Feb 1, 2004

Hi

I am using SQL 2000 I have the following code. When saving it, I am getting an error:
There is already an object named '##tbl' in the database

This is although #tbl is dropped.
Is threrea way to avoid this error? the only work around I found was to create a string with the SQL command and call EXEC, but I don't like this solution as it prevents early compilation of the procedure.

declare @x int
set @x=1
IF @x=0
begin
create table #tbl (
abc int
)
drop table #tbl
end

IF @x=1
begin
create table #tbl (
abc int
)
drop table #tbl
end

Than you.

Temporary Table

Apr 11, 2006

I have the following fields in table A:

GL_ID|GL_Name_VC| Amount |Period_TI|Year_SI|
===================================================
1000| Sales | -20,000.00 | 01 | 2005
===================================================
1000| Sales | -10,000.00 | 02 | 2005
===================================================
1001| Cost | 5,000.00 | 01 | 2005
===================================================
1001| Cost | 5,000.00 | 02 | 2005

the fields above have the following datatype:

Fields | Datatype
===================================
GL_ID | Integer
GL_Name_VC | Variable Character
Amount | Integer
Period_TI | TinyInteger
Year_SI | SmallInteger

The above database is running on Microsoft SQL Server 2000 and i would like to query
for a report that looks something as below:

Description | Period 01 | Period 02 | Year to Date
=========================================================
Sales | 20,000.00 | 10,000.00 | 30,000.00
Total Sales | 20,000.00 | 10,000.00 | 30,000.00

Cost | 5,000.00 | 5,000.00 | 10,000.00
Total Cost | 5,000.00 | 5,000.00 | 10,000.00
=========================================================
Profit | 15,000.00 | 5,000.00 | 20,000.00

The above report would list 4 columns, with the last column being a calculated field as a sum of
Period01 + Period02 Amount, sorted by GL_ID and group under a summation row called
Total Sales & Total Cost.There would be a net amount appearing as Profit (Total Sales-Total Cost).

Guys, hope someone out there can help me with the sql command for the above report?

order

Since the second table is somehow only temporary table (having at the front ajax script), i need the third table to store user's ID and all the info from second table.

What would be the easiest way to do it, since the first table contains only one row per user and the second one 40 rows per user.

Temporary Table Pb

May 9, 2007

Hi



I call some SQL server procedures via OLEDB under Visual C++.

[ Commands like " EXEC myProc 'param1', 'param2' " ]

My connection string is Provider=SQLOLEDB;Data Source=.SQLEXPRESS;Integrated Security=SSPI;Initial File Name=C:devsrcindb.mdf





I encounter a pb when there is a 'SELECT (...) INTO #table' into my db procedure.



Something like:

ALTER PROCEDURE myProc

AS



SELECT 1 as 'return1', 2 as 'return2' into #table

SELECT * FROM #table



RETURN



works of course very well when I call it from Visual or Server Management Studio Express

but doesn't return any recordset when I call it from OLEDB.



2nd thing:

SELECT 1 as 'return1', 2 as 'return2' into table

SELECT * from table



-> table is created [I can see it in the db], but no selection is returned to my OLEDB caller.



Is it a security pb ?
