I have never created a stored procedure before so Not even sure what i am trying to do is even viable
Aim – Create a stored procedure which truncates a table at a certain time of the day
Table name Dan.Stg_Jitter_Opp want to truncate table at 11am
table2 is intially populated (basically this will serve as historical table for view); temptable and table2 will are similar except that table2 has two extra columns which are insertdt and updatedt
process:
1. get data from an existing view and insert in temptable
2. truncate/delete contents of table1
3. insert data in table1 by comparing temptable vs table2 (values that exists in temptable but not in table2 will be inserted)
4. insert data in table2 which are not yet present (comparing ID in t2 and temptable)
5. UPDATE table2 whose field/column VALUE is not equal with temptable. (meaning UNMATCHED VALUE)
* for #5 if a value from table2 (historical table) has changed compared to temptable (new result of view) this must be updated as well as the updateddt field value.
I was just looking at an SSIS package someone else set up and I went into one of the execute SQL tasks and it is calling a stored procedure to truncate a table. There are a lot of places that tables are truncated within this SSIS package. But each one the 'database', 'owner', and 'table' name are hard coded.
Like this: exec dbo.uspTruncateTable 'dbname', 'dbo', 'tblname'
Of course there are different names, just changed for an example.
Here is the code in the Stored Procedure.
CREATE procedure [dbo].[uspTruncateTable]
@nDatabase varchar(255),
@nOwner varchar(255),
@ntable varchar(255)
as
declare @sqlString nvarchar(max)
set @sqlString = 'Truncate Table ' + @nDatabase + '.' + @nOwner + '.' + @ntable
exec (@sqlString)
This just seems like an unneeded step, just code the 'truncate table dbname.dbo.tblname'.
I have a procedure that uses varchar(max) as output parameter, when I tried to retrieve
the result of calling the procedure, the result is truncated to 4000 character. Is this a driver bug?
Any workaround?
Here is the pseudo code:
create Procedure foo(@output varchar(max))
{
set @foo = 'string that has more than 4000 characters...';
return;
}
Java code:
CallableStatement cs = connection.prepareCall("{call foo ?}");
cs.registerOutputParameter(1, Types.longvarchar); // also tried Types.CLOB.
cs.execute();
String result = cs.getString(1); // The result is truncated to 4000 char.
-- Also tried
CLOB clob = cs.getClob(1);
long len = clob.length(); // The result is 4000.
Thanks,
Eric Wang
which is more efficient...which takes less memory...how is the memory allocation done for both the types.

View 2 Replies View RelatedCan I invoke stored procedure stored inside from a user defined table column?
View 5 Replies View RelatedHello to all!
I have a table name stored in a scalar variable (input parameter of my stored procedure). I need to run SQL statement: SELECT COUNT (*) FROM MyTable and store the result of my query in a scalar variable:
For example:
declare @countRows int
set @countRows = (select count(*) from MyTable)
The problem is that the name of MyTable is stored in the input variable of my stored procedure and of corse this does not work:
declare @countRows int
set @countRows = (select count(*) from @myTableName)
I also tried this:
declare @sqlQuery varchar(100)
set @sqlQuery = 'select count(*) from ' + @myTableName
set @countRows = exec(@sqlQuery)
But it looks like function exec() does not return any value...
Any idea how to solve this problem?
Thanx,

I don't know if it's a local issue but I can't use temp table or table variable in a PP query (so not in a stored procedure).
Environment: W7 enterprise desktop 32 + Office 2012 32 + PowerPivot 2012 32
Simple example:
declare @tTable(col1 int)
insert into @tTable(col1) values (1)
select * from @tTable
Works perfectly in SQL Server Management Studio and the database connection is OK to as I may generate PP table using complex (or simple) queries without difficulty.
But when trying to get this same result in a PP table I get an error, idem when replacing table variable by a temporary table.
Message: OLE DB or ODBC error. .... The current operation was cancelled because another operation the the transaction failed.
Here is the scenario,
I have 2 stored procedures, SP1 and SP2
SP1 has the following code:
declare @tmp as varchar(300)
set @tmp = 'SELECT * FROM
OPENROWSET ( ''SQLOLEDB'', ''SERVER=.;Trusted_Connection=yes'',
''SET FMTONLY OFF EXEC ' + db_name() + '..StoredProcedure'' )'
EXEC (@tmp)
SP2 has the following code:
SELECT *
FROM SP1 (which won't work because SP1 is a stored procedure. A view, a table valued function, or a temporary table must be used for this)
Views - can't use a view because they don't allow dynamic sql and the db_name() in the OPENROWSET function must be used.
Temp Tables - can't use these because it would cause a large hit on system performance due to the frequency SP2 and others like it will be used.
Functions - My last resort is to use a table valued function as shown:
FUNCTION MyFunction
( )
RETURNS @retTable
(
@Field1 int,
@Field2 varchar(50)
)
AS
BEGIN
-- the problem here is that I need to call SP1 and assign it's resulting data into the
-- @retTable variable
-- this statement is incorrect, but it's meaning is my goal
INSERT @retTableSELECT *FROM SP1
RETURN
END
My Pocket PC application exports signature as an image. Everything is fine when choose Use SQL statements in TableAdapter Configuration Wizard.
main.ds.MailsSignature.Clear();
main.ds.MailsSignature.AcceptChanges();
string[] signFiles = Directory.GetFiles(Settings.signDirectory);
foreach (string signFile in signFiles)
{
mailsSignatureRow = main.ds.MailsSignature.NewMailsSignatureRow();
mailsSignatureRow.Singnature = GetImageBytes(signFile); //return byte[] array of the image.
main.ds.MailsSignature.Rows.Add(mailsSignatureRow);
}
mailsSignatureTableAdapter.Update(main.ds.MailsSignature);
But now I am getting error "General Network Error. Check your network documentation" after specifying Use existing stored procedure in TableAdpater Configuration Wizard.
ALTER PROCEDURE dbo.Insert_MailSignature( @Singnature image )
AS
SET NOCOUNT OFF;
INSERT INTO MailsSignature (Singnature) VALUES (@Singnature);
SELECT Id, Singnature FROM MailsSignature WHERE (Id = SCOPE_IDENTITY())
For testing I created a desktop application and found that the same Code, same(Use existing stored procedure in TableAdpater Configuration Wizard) and same stored procedure is working fine in inserting image into the table.
Is there any limitation in CF?

I am working with the following two tables:
Category(NewID,OldID)
Link(CategoryID,BusinessID)
All fields are of Integer Type.
I need to write a stored procedure in sql 2000 which works as follows:
Select all the NewID and OldID from the Category Table
(SELECT NewID,OldID FROM Category)
Then for each rows fetched from last query, execute a update query in the Link table.
For Example,
Let @NID be the NewID for each rows and @OID be the OldID for each rows.
Then the query for each row should be..
UPDATE Link SET CategoryID=@CID WHERE CategoryID=@OID
Please help me with the code.

Hello
Is it possible to insert data into a temp table with data returned from a stored procedure joined with data from another table?
insert #MyTempTable
exec [dbo].[MyStoredProcedure] @Par1, @Par2, @Par3
JOIN dbo.OtherTable...
I'm missing something before the JOIN command. The temp table needs to know which fields need be updated.
I just can't figure it out
Many Thanks!

Hi, How can I store a stored procedure's results(returning dataset) intoa table?Bob*** Sent via Developersdex http://www.developersdex.com ***Don't just participate in USENET...get rewarded for it!
View 1 Replies View Related Here is my issue I am new to 2005 sql server, and am trying to take my old data which is exported to a txt file and import it to tables in sql. The older database is non relational, and I had made several exports for the way I want to build my tables. I built my packages fine and everything is working until I start building relationships. I remove my foreign key and the table with the primary key will get updated for the package again. I need to update the data daily into sql, and once in it will only be update from the package until the database is moved over.
It will run and update with a primary key until I add a foreign key to another database.
Here is my error when running the package when table 2 has a foreign key.
[Execute SQL Task] Error: Executing the query "TRUNCATE TABLE [consumer].[dbo].[Client] " failed with the following error: "Cannot truncate table 'consumer.dbo.Client' because it is being referenced by a FOREIGN KEY constraint.". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly.
Hi,
I am having 2 tables. One is main table and another is history table. Whenever I update the main table, I need to insert the all the main table data to History table, before updating the main table.
Overall it is like storing the history of the table updation.
How do i write a stored procedure for this?
Anybody has done this before?
Pls help me.
I've never used a stored procedure before - let alone created one. how to append records from table A to table B.
View 1 Replies View Relatedi did a Stored Procedure to truncate a table. it contains lots of crap from testing the site. just a simple 1 ALTER PROCEDURE dbo.TruncateUploads
AS
TRUNCATE TABLE Uploads but it says "Cannot truncate table 'Uploads' because it is being referenced by a FOREIGN KEY constraint." then i make NULL all foreign keys and try still cannot. then i did it manually deleting all records then can! but why can't i truncate it? isn't it the same as removing all values plus having the primary keys to start from 0?
How can i TRUNCATE my table (removes rows that were produced at testing), so that in the actual running the automated IDNumber for my table start with 1.
View 6 Replies View Relatedhi, I have two tables members table and orders table.
I have 2 records in members table and zero records in order table.
When I try to truncate members table I get an error message.
cannot truncate table members,because it is being referenced by a FOREIGN KEY constraint.
this what blows my head, There is no records in orders table. so why would the constraint enforced when there is no data in the order table. I created same table in access and I was able to delete a member from the members table. any comments.
thanks

I have several very large tables and sometimes I need to clean them.
It's known that TRUNCATE TABLE works much faster than DELETE, but impossible to use TRUNCATE TABLE on a table referenced by a FOREIGN KEY constraint... Is it possible temporary disable (not delete) constraints and after complition of TRUNCATE enable them ?
Hi,
(From Bol)
"You Cannot Use Truncate Table On A Table Referenced By A Foreign Key
Constraint;"
1) States
Statecode TinyintPrimary Key
Statename Varchar(25)
2) Rivers
RivercodeSmallint Primary Key
RivernameVarchar(40)
3) Riverinstates
StatecodeTinyint,
RivercodeSmallint,
Constraint Pkriverinstates Primary Key(Statecode,Rivercode),
Constraint Fkriverinstates
Foreign Key (Statecode) References States(Statecode),
Foreign Key (Rivercode) References Rivers(Rivercode)
after removing all rows from RiverInStates Table using TRUNCATE and the command completed successfully.
when i tried to remove all rows from Rivers table , i got the following error.
"Server: Msg 4712, Level 16, State 1, Line 76
Cannot truncate table 'rivers' because it is being referenced by a FOREIGN
KEY constraint."
i thought the error may be due to the "Fkriverinstates" FOREIGN KEY CONSTRAINT. so i DROPped the constraint with
ALTER TABLE RiverinStates DROP CONSTRAINT Fkriverinstates
even after DROPping the constraint, im getting the same error
can any one point out where the problem is?
thanks in advance
what is the best way to truncate/delete records from a table at a certain time of the day...... i'm sure this is a simple ?, but i'm still learning sql.

Hi,
I am having a SP which returns two Rowsets:
create proc GetSalesDetails as
select CustName, ProductPurchased from Customers where PurchaseDate > '10/10/2006'
select ProductName from Products where SalesDate > '10/10/2006'
Now in my code when I am filling the Dataset using this SP then it is giving the Table Names as "Table" and "Table1". Is there any way to get the actual table names respectively?
Cheers,

How can be used in a stored procedure the name of a table that was passed as a varchar parameter? The table name must be used in the "from" clause of a "select" statement without calling the "EXECUTE" or "sp_executesql". Is it possible?

View 1 Replies View RelatedI am doing the following-
begin transaction
truncate table Acounts
select * from Accounts
rollback
select * from Accounts
The first select is returning 0 rows as expected. But after doing the rollback I expected to yet see 0 rows as truncate is not logged so cannot be rolled back. But to my suprise I see that there are rows.
So the rollback is rolling back the truncate table statement. Can someone please explain this????
I know that only the owner of a table can truncate it.
I want a user to run a procedure that truncates a table. Both the procedure and the table are owned by dbo, however the system says that the user can't truncate the tables because she doesn't have permission. The user has dataread and datawrite global permissions, and I do not want to give her dbo perimssions.
Is there a solution to this?
Hi all,
Is it possible to TRUNCATE a table and BCP data into the same table in one

My problem is that I want to refresh(delete and via BCP append new data) a
table without disturbing running applications. Can I run BCP from a
SQL-script or a stored procedure?

Does anybody know of a way to allow non-administrators to execute the truncate table statement?
I have developers that from time to time need to move data between their databases usinge the DTS wizard. Most of their tables have identity columns and in order retain the identity seed, they need to click on the option to enable identity insert. This option isn't available to non administrators.
