Hi,
I'm quite new to SQL 2000 and I've been trying to find an easy way to truncate a number of tables in a script. The table names are all prefixed with 'RESULTS_' so they are easy enough to identify. Is this fairly straightforward?
I frequently have tables that I want to empty and refill. I thought I read somewhere that trucating was a bad idea, example:
Truncate table tblFruits
A bad idea because of something to do with the log? I'm a beginner so I don't understand transaction processing very well, or logs.
Is it better to delete the table and rebuild it in code before you add the values?
Anyone?
I tried the following code...thought I could trap the RI Error and move on...
It raises all the way out though....
Server: Msg 4712, Level 16, State 1, Line 1
Cannot truncate table 'myTable99' because it is being referenced by a FOREIGN KEY constraint.
I thought you could trap it this way...
CREATE TABLE myTable99(Col1 int PRIMARY KEY)
GO
CREATE TABLE myTable00(Col1 int, Col2 int, PRIMARY KEY(Col1,Col2), FOREIGN KEY (Col1) REFERENCES myTable99(Col1))
GO
INSERT INTO myTable99(Col1) SELECT 1
INSERT INTO myTable00(Col1, Col2) SELECT 1,2
GO
CREATE PROC myDynamicSQL99 @sql varchar(8000) AS EXEC(@sql)
GO
DECLARE @error int, @TABLE_NAME sysname, @sql varchar(8000), @x int, @rc int
SELECT @error = 0, @x = 0
DoItAgain:
DECLARE myCursor99 CURSOR
FOR
SELECT TABLE_NAME
FROM INFORMATION_SCHEMA.Tables
WHERE TABLE_NAME LIKE 'myTable%'
ORDER BY TABLE_NAME DESC
OPEN myCursor99
FETCH NEXT FROM myCursor99 INTO @TABLE_NAME
WHILE @@FETCH_STATUS = 0
BEGIN
SELECT @SQL = 'TRUNCATE TABLE ' + @TABLE_NAME
SELECT @SQL
EXEC @rc = myDynamicSQL99 @SQL
SELECT @Error = @@Error
SELECT 'Error Code: ' + CONVERT(varchar(15),@Error) + ' @rc: '+ CONVERT(varchar(15),@rc)
IF @Error <> 0
SELECT @x = @x + 1
FETCH NEXT FROM myCursor99 INTO @TABLE_NAME
END
CLOSE myCursor99
DEALLOCATE myCursor99
IF @x <> 0
BEGIN
SELECT @Error = 0
GOTO DoItAgain
END
GO
DROP PROC myDynamicSQL99
DROP TABLE myTable00
DROP TABLE myTable99
GO
Hi! I have a general SQL CE v3.5 design question related to table/file layout. I have an system that has multiple tables that fall into categories of data access. The 3 categories of data access are:
1 is for configuration-related data. There is one application that will read/write to the data, and a second application that will read the data on startup.
1 is for high-performance temporal storage of data. The data objects are all the same type, but they are our own custom object and not just simple types.
1 is for logging where the data will be permanent - unless the configured size/recycling settings cause a resize or cleanup. There will be one application writing alot [potentially] of data depending on log settings, and another application searching/reading sections of data.
When working with data and designing the layout, I like to approach things from a data-centric mindset, because this seems to result in a better performing system. That said, I am thinking about using 3 individual SDF files for the above data access scenarios - as opposed to a single SDF with multiple tables. I'm thinking this would provide better performance in SQL CE because the query engine will not have alot of different types of queries going against the same database file. For instance, the temporal storage is basically reading/writing/deleting various amounts of data. And, this is different from the logging, where the log can grow pretty large - definitely bigger than the default 128 MB. So, it seems logical to manage them separately.
I would greatly appreciate any suggestions from the SQL CE experts with regard to my approach. If there are any tips/tricks with respect to different data access scenarios - taking into account performance, type of data access, etc. - I would love to take a look at that.
Thanks in advance for any help/suggestions,
Bob
I am attempting to how to truncate list of tables using STP. That is decalre a cursor for a list table names and then to truncate the table names one by one.
The code below shows what I want to achieve. I want to truncate all the tables with names beginning with ZZ but this is failing. I have tried using both delete and truncate.
Is it possible and what do I need to do?
-- Code
SET QUOTED_IDENTIFIER Off
GO
SET ANSI_NULLS ON
GO
create PROCEDURE dbo.Empty_ZZ
AS
DECLARE @tablename sysname
DECLARE @localname varchar(50)
DECLARE ZZtablenames_cursor CURSOR FOR
select [name]
from sysobjects
WHERE [xtype] = 'U'
and name like 'ZZ %'
OPEN ZZtablenames_cursor
FETCH NEXT FROM ZZtablenames_cursor
into @tablename
WHILE @@FETCH_STATUS = 0
BEGIN
set @localname = '[' + @tablename + ']'
TRUNCATE + @localname
FETCH NEXT FROM ZZtablenames_cursor
END
CLOSE ZZtablenames_cursor
DEALLOCATE ZZtablenames_cursor
GO
SET QUOTED_IDENTIFIER OFF
GO
SET ANSI_NULLS ON
GO
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'.
Guys,
I have 600 tables in my database, out of which 40 tables are look up value tables. I want generate truncate scripts which truncates all the tables in order of Parent child relationship excluding lookup tables. Is there any way to do this apart from figuring out Parent Child relationship and then writing the truncate statements for each of the table.
For example
EmployeeDetail table references Employee table
DepartmentDetail table references Department table
Department table references Employee table
My truncate script should be
TRUNCATE TABLE DEPARTMENTDETAIL
TRUNCATE TABLE EMPLOYEEDETAIL
TRUNCATE TABLE DEPARTMENT
TRUNCATE TABLE EMPLOYEE
IS there any automated way to figure out parent and child tables and generate truncate script for the same.
Thanks

I have a requirement where in i have around 15 different flat files , filenames are fixed but folder path can be changed(i think i should use a variable for folder path). These 15 files data should go to their respective tables in the database.
Whether I need to create separate data flow task for each file or separate package? In addition to these, example : while importing product data into product table, if product ID already exists, we need to ignore it and upload only the new records.
I have an excel file that has multiple sheets and I need to import data from each separate sheet to a separate table using SSIS.
E.g. Sheet A data should go to Table A and Sheet B data should go to Table B and so on. Is it possible to do this with out using script task.
I have just taken over the job of sorting out a rather poorly designed database. It looks like it was 'upsized' from an access database to the SQL server. The SQL server is the 2000 version.
Now I am trying to generate a report of what the students in the database are owing by referencing the Receipt table and then all the available payment methods and allocations. I was wondering if there was anyway to work out data being displayed twice (Let me demonstrate)
Note1: All the tables are linked by a key of ReceiptNo. From what I can see there is a table for every payment type and allocation but no link between the two other then the receipt number.
Using the query:
SELECT T_Receipt.ReceiptNo, T_cheque.Amount AS Chq_Amount, T_credit.Amount AS Cre_Amount, StandingOrder.Amount AS Stn_Amount,
T_BankTransfer.amount AS Bnk_Amount, T_cash.TotalAmount AS Cas_Amount, T_RentPayment.AmountPayed AS Ren_Paid,
T_AdminPayment.AmountPaid AS Adm_Paid, T_InternetBilling.Total AS Int_Paid, T_Utilities.AmountPaid AS Util_Amount,
T_InvoicePayment.amountPaid AS Inv_Paid, T_OtherPayments.paymentAmount AS Oth_Paid, T_parkingBill.paymentAmount AS Prk_Paid,
T_TelephoneBills.TelephoneCredit AS Tel_Paid, T_DepositPayment.[Deposit payment] AS Dep_Amount, T_Receipt.cancelled AS Canceled,
T_Receipt.RemittanceReceiptNo AS Rec_Ref, T_Receipt.Student
FROM T_Receipt INNER JOIN
T_DepositPayment ON T_Receipt.ReceiptNo = T_DepositPayment.receiptNo LEFT OUTER JOIN
T_RentPayment ON T_Receipt.ReceiptNo = T_RentPayment.RentPaymentNo LEFT OUTER JOIN
StandingOrder ON T_Receipt.ReceiptNo = StandingOrder.ReceiptNo LEFT OUTER JOIN
T_TelephoneBills ON T_Receipt.ReceiptNo = T_TelephoneBills.ReceiptNo LEFT OUTER JOIN
T_parkingBill ON T_Receipt.ReceiptNo = T_parkingBill.ReceiptNo LEFT OUTER JOIN
T_OtherPayments ON T_Receipt.ReceiptNo = T_OtherPayments.ReceiptNo LEFT OUTER JOIN
T_InvoicePayment ON T_Receipt.ReceiptNo = T_InvoicePayment.receiptNo LEFT OUTER JOIN
T_cash ON T_Receipt.ReceiptNo = T_cash.ReceiptNo LEFT OUTER JOIN
T_AdminPayment ON T_Receipt.ReceiptNo = T_AdminPayment.ReceiptNo LEFT OUTER JOIN
T_BankTransfer ON T_Receipt.ReceiptNo = T_BankTransfer.receiptNo LEFT OUTER JOIN
T_Utilities ON T_Receipt.ReceiptNo = T_Utilities.receiptNo LEFT OUTER JOIN
T_credit ON T_Receipt.ReceiptNo = T_credit.ReceiptNo LEFT OUTER JOIN
T_cheque ON T_Receipt.ReceiptNo = T_cheque.ReceiptNo LEFT OUTER JOIN
T_InternetBilling ON T_Receipt.ReceiptNo = T_InternetBilling.ReceiptNo
GROUP BY T_Receipt.Student, T_Receipt.ReceiptNo, T_cheque.Amount, T_credit.Amount, StandingOrder.Amount, T_BankTransfer.amount, T_cash.TotalAmount,
T_AdminPayment.AmountPaid, T_InternetBilling.Total, T_Utilities.AmountPaid, T_InvoicePayment.amountPaid, T_OtherPayments.paymentAmount,
T_parkingBill.paymentAmount, T_TelephoneBills.TelephoneCredit, T_Receipt.cancelled, T_Receipt.RemittanceReceiptNo,
T_DepositPayment.[Deposit payment], T_RentPayment.AmountPayed, T_Receipt.Student
HAVING (T_Receipt.Student LIKE N'06%')
Which gives a result of:
RecNo.
30429
Cheque
250
Deposit
250
30429
679.98
250
This is fine but when I do analysis on this it appears as though the student has paid two deposit payments. I was wondering with out querying each table independently from an application if there was a criteria to specify that I only get one deposit result.
So as such say, give me all the payments but I only want one result from the other tables. I though about discrete but that wouldn't work here.
Hi!
I have 7 source databases and one target database, all using the same structure. The structure is made of 10 tables, with foreign key constraints.
I need to merge the source databases into the target (which won't have any data before that process, but will already have the correct schema), and to keep the relationships between the records.
I know how to iterate over the source databases (with SMO foreach), but I'd like to know if someone can advise the best copy method for that context in SSIS ? (I don't want to keep the primary keys, but I need to keep the relationships...)
Any pointer most welcome!
best regards and thanks

I have a couple of hundred flat files to import into database tables using SSIS.
The files can be divided into groups by the format they use. I understand that I could import each group of files that have a common format at the same time using a Foreach Loop Container.
However, the example for the Foreach Loop Container has multiple files all being imported into the same database table. In my case, each file needs to be imported into a different database table.
Is it possible to import each set of files with the same format into different tables in a simple loop? I can't see a way to make a Data Flow Destination item accept its table name dynamically, which seems to prevent me doing this.
I suppose I could make a different Data Flow Destination item for each file, in the Data Flow. Would that be a reasonable solution, or is there a simpler solution, or should I just resign myself to making a separate Data Flow for every single file?
With a database size of almost 2 GB, I run the 'truncate table eventlog command' which completes successfully, but the database size only decreases by about 10 MB so stays too large - indeed the number of rows in the eventlog table is minimal, but the otehr tables in this database don't show such an amount of tables large enough to cause the size issue either. What could be the reason and how can I reduce it (possibly truncating another table but then which one, how could I determine which is too large and needs truncating?).

How to insert single row/multiple rows into multiple tables by using single insert statement.
View 1 Replies View RelatedI need to be able to bulk insert a bunch of tables from their corresponding flat file. I have created an XML file (see below) which has the file name/table name pair at each node. I then created a ForEachLoop task and used the Node enumeration type and the following OuterXpathString: ReferenceFiles/File. At this point I get lost. How do I pass the 2 inside node values (file name and table name) to variables which I can then use as expressions for the bulk insert task inside the Foreach?
Here is XML file:
Code Snippet

<FileName>Ref_Configs.txt</FileName>

I used the data export wizard to export a single table to a single flat file (multiple wasn't allowed). I saved the package as a *.dtsx file which I'm attempting to edit to add the additional tables.
Creating additional sources is fairly easy copy of the first source and change to the table name.
I've tried copying the destination connection and changing to a new text file, but can't get past having to add each column manually to the new destination.
How can I duplicate the mapping that must be taking place in the wizard in the *.dtsx editing environment?
This seems like a simple / common task, but I've been unable to find a solution.
Thanks, Richard

Hello,
I am in the progress of designing a new section of my database and was thinking of creating a hole new database instead of just creating tables inside the database. My question is can you JOIN multiple tables in an SQL Statement from multiple databases. Ie, In the Management program I have a database called 'Convention' and another one called 'Services', inside the two databases there are many tables. Can I link say tblRegister from Convention to tblUser in Services?
Thanks

Hi,
I have searched but not found quite the best way to look at this so far..
I have an application that outputs data to several text files (up to 30). These have commonality by an object name, but then contain completely different column data.
In DTS I had each of the source text file connections going to one OLE DB connection and then individual transform data tasks pointing to the one OLE DB connection.
Looking at SSIS, it would appear that I would need to have one source and one destination for each of these and therefore 30 parallel data flows?
Just wondering if there is a neater way of doing this??
It is a regular data import that happens a few times a day - the text files are named the same as the SQL tables - ie app_userdata.txt goes to app_userdata table.
Hope that explains ok and thanks in advance.

Hello all,
Being still a relative newcomer to SQL Server (people may say I'm trying to take on too much being somewhat inexperienced once they read about the problem I'm trying to tackle, but alas...) I'm running into the following problem: I need to create tables in my user database on the fly (using Stored Procedures) so that each table can be created many times in the database but only once for every user. The tables should be named something like "username.Table1", "username.Table2" etc. as opposed to "dbo.Table1". I then want to use the stored procedure from .NET/C# in my web application, so that i can create the complete set of usertables for each of my clients.
Now, I tackled the stored procedure part (that is, it creates all the tables I need with all the parameters I want) and am able to use it from my web application (which took some time to learn but proved quite easy to do), but I cannot seem to get it coupled to the current user (instead of the dbo). Every time I trie, the tables are created as dbo.Table1 and when I try to create a new set, it gives a warning ("table with name such and so already exists..."). I made sure to log in as an authenticated user (using forms authentication) before trying to create the tables but this gives the aforementioned result.
What am I doing wrong? I use Visual Web Developer Express, SQL Server 2005 Express and IIS version 5.1
Please help :-D

I am trying to write (my first, unfortunatly) DTS, and am having some problems.
I need to be able to import multiple flatfiles (all in the same format, just with different schema), each one going into a different table. I have written an application to call my DTS, sending it variables for the tablename and the filename. This works fine when I test it on a single flatfile.
My problem is, the Tranformation object does not reset after each DTS call, so I get "Column does not exist" errors after the first successful import. I can go into the DTS Manager and reset the Transformation options, but that would defeat the purpose of automation. Is there anyway to reset, or another technique, the Transformation object so that it will continuosly work on files that use different schema?
I am very new at DTS, so please consider me "ignorant" when replying.
Thanks in advance.

Please forgive the elementary nature of my question, but could someone please explain the differences between these two database backup types:
1. Log backup
2. Log backup no truncate
From what I understand and have read, the "no truncate" backup method keeps the entire transaction log indefinitely. Using the truncation method, the transaction log is either 1) compressed or 2) cleaned up so that any completed transactions are removed from the log. Which one of these is true?
And, for the big question: is it better to run a backup of the transaction log with truncation or not? Our current backup scheme is similar to the following:
Full backup every 24 hours
transaction log backup every hour with no truncation
Should we insert a truncation backup somewhere in here? What is the danger of removing (or compressing) parts of the transaction log? Will this affect the restore process?
Thanks in advance!
Hi
I am trying to import an excel spreadsheet into a sql server database. The problem is I need the information in the spreadsheet to be imported into 3 different tables. I thought of transfering all details into a temporary table and then setting 3 triggers for each transfer of information. But this seems very inefficient. I know there should be an easier way to do this in dts.
Any help would be greatly appreciated
Thanks
Hello,
I have 2 tables I am using as test, and for the life of me I can't figure this out.
Table: stats
Columns: ID, Name, Goals, Assists, Points
Example: 1, George, 1, 1, 2
Table: Players
Columns: ID, Name, Pick1, Pick2, Pick3
Example: 1, Bob, 1, 4, 7
I want to find the SUM value of stat.Points, where Players.Pick1 = stats.ID for all picks.
Then Grouping them by Players.name
Am I creating the database schema wrong for this?
