Creating Temporary Table
Jul 20, 2005
Hi,
How can I create a temporary table say "Tblabc" with column fields
ShmCoy char(2)
ShmAcno char(10)
ShmName1 varchar(60)
ShmName2 varchar(60)
and fill the table from the data extracted from the statement...
"select logdetail from shractivitylog"
The above query returns single value field the data seperated with a '·'
Ex:
BR··Light Blue Duck··
in this case I should get
ShmCoy = 'BR'
ShmAcno = ''
ShmName1 = 'Light Blue Duck'
ShmName2 = ''
I want to do this job with single SQL query. Is it possible. Pls help.
Herewith I am providing the sample data
BR··Light Blue Duck··
·0234578···
BR··Aqua Duck··
·0234586···
UB··Aqua Duck··
Regards,
Omav

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

Using SQL against a DB2 table the 'with' key word is used todynamically create a temporary table with an SQL statement that isretained for the duration of that SQL statement.What is the equivalent to the SQL 'with' using TSQL? If there is notone, what is the TSQL solution to creating a temporary table that isassociated with an SQL statement? Examples would be appreciated.Thank you!!

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,

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] .....

Hi All,
In my SQL I am having temporary tables. And in Microsoft SQL Server Management Studio (Microsoft SQL Server 2005) whenever I execute sql statement its working fine & I am getting the records.
My SQL statement is using 2 databases as follows:
1.PerformanceDeficiencyNotice
2.HRDataWarehouse
Both the above databases are SQL SERVER 2000(80) with a compatibility level of 80.
The problem is when I am trying to create a new view with my sql statement and when I am saying “Verify SQL Syntax�, I am getting an error as “Invalid Object Name ‘#pdninfo’.
And when I am saying “execute SQL�, I am getting an error as “Unable to parse query text� but when I am continuing with the error, the sql statement is running and I am getting the data.
And now when I am trying to save the view I am getting the error as below
“Incorrect syntax near the keyword ‘INTO’�.
Views or functions are not allowed on temporary tables. Table names that begin with ‘#’ denote temporary tables.
Please suggest how to solve this problem. Any help is greatly appreciated.
Thank You
MY SQL Statement is as follows:

In the T-SQL below, I retrieved data from two queries and I've tried to join them to create a report in SSRS 2008 R2. The SQL runs, but I can't create a report from it. (I also couldn't get this query to run in an Excel file that connects to my SQL Server data base. I've used other T-SQL queries in this Excel file and they run fine.) I think that's because I am creating temporary tables. How do I modify my SQL so that I can get the same result without creating temporary tables?
/*This T-SQL gets the services for the EPN download from WITS*/
-- Select services entered in the last 20 days along with the MPI number and program code.
SELECT DISTINCT dbo.group_session_client.note, dbo.group_session_client.error_note, dbo.group_session_client.group_session_id,

I have a table that includes the html-output of different parts of my pages. This table grows very big very fast, and rows older than 24 hours are useless.
My question is if it is possible to have temporary rows, whose are automatically deleted after these 24 hours? And then how to accomplish that?

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.

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.

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.

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.

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 ?

Hello once again,
My last question concerns (temporary) tables. In a web form (VWD Express, Asp,Net 2.0, VB, .mdf db, Ajax) I have two gridviews. One gets its data from textboxes and dropdownlists as the user clicks an ok button. This data is then sent to a "junk" table in the db. The other gridview retrieves this data "automatically" and displays the data, filtered and grouped by some SQL statements. When the user finally clicks an Insert record button, the data from this second gridview gets inserted in another table in the db and the data from the first "junk" table is disposed.
I guess it shouldn't be necessary to insert, retrieve, and delete the data in and from the "junk" table. Even though it does work like a charm, I guess it would be better if I could do it wit hsome kind of "temporary table", array or the like so that the db wouldn't need to be updated to this extent. Still, I really like the simplicity of using gridviews and the rest of the page's code is complex enough, so I don't really want to substitute this behaviour for tons of hand-written, hard-to-follow, and hard-to-integrate code.
What are my options? Any help would be greatly appreciated.

Hi,
Can any of you tell me what is right?
When we are writing a big query that against to 25+ tables (it has lots of lookup and lots of business logic in it so it will have lots of left outer joins, right outer joins, inner join, UNION, group by, and lots of SQL server functions) should we put everything in one select statement? Or we should create lots of temporary tables and then join them together?
My friend told me that I should use one statement instead of lots of temp tables in order to reduce the physical read. He does not like the temp table idea since there will be lots of user running the query in the same time and it will use lots of space. But I don’t believe that is true. (I believe when you put everything in one statement, SQL server still needs to create the result set in the temp db.) There will be lots of join going on and it could hurt the performance.
I believe that
1.We should create the temp tables and then join the temp tables together later to get the final results. we can create the index on the temp table at runtime.
2.If the order of columns in the index does not match to our where clause, then the index is useless.
3.If there is a SQL function in the where clause, the index is useless. (for example, where Datepart(yy, orderdate)=’1998’)
4.If there is a NOT in the where clause, the index is useless.
What do you think? Are you agree with me?
Following is the query. Is there any better way to do this?
Select d.Description as Division,
c.Description as Region,
b.StateCode as State,
b.FacilityNumber,
b.Name as FacilityName,
(Case When a.ExitDate Is Not Null Then Convert(Varchar(10),a.ExitDate,101)
Else 'Pending' End) as PriorStdSurveyExit,
(Case When a.ExitDate Is Not Null And a.IJValid > 0
Then Convert(Varchar(10),a.ExitDate+89,101)
Else '' End) as ThreeMonthWindow,
(Case When a.ExitDate Is Not Null Then Convert(Varchar(10),a.ExitDate+179,101)
When a.IJValid > 0 Then Convert(Varchar(10),a.ExitDate+179,101)
Else 'Pending' End) as SixMonthWindow,
(Case When a.ExitDate Is Not Null Then Convert(Varchar(10),a.ExitDate+450,101)
When a.IJValid > 0 Then Convert(Varchar(10),a.ExitDate+450,101)

Hope somebody can give me some advice .
We are having some issues with temporary tables (with # prefixes) within Stored Procedures.
When running a profile trace on them, the stored proc quite happily creates the temp # table (in fact several of them) but whenever it hits the first statement inserting data into one of them (and it doesn't matter which one), there is a 5-6 second delay.
By commenting out one and moving to the next piece of code, the same thing happens.
Following which, the rest of the Stored Prco runs fine and subsequent inserts into the # temp tables also run efficiently.
Is the stored proc getting recompiled perhaps ?
Any advice woul;d be appreciated.
we are running SQL Server 7.0, dont know whether that helps ?

I am trying to create a view using to three queries below and I get the error message Views or functions are not allowed on temporary tables. Is there a way to do that or is there a way to combine the three queries below so I don't have to use a temp table so I create a view?
--Query 1
SELECT * INTO #MOVEMENTS
FROM [GW_DW].[dbo].[DimStatusHistory] d
WHERE TransferFromToProgram<>''
AND d.Status=12
;
--Query 2
SELECT DISTINCT
[Code] ....
