How To Avoid For..each When There's No Data

Oct 25, 2007



Hi everyone,

As first task I've got Data Flow which loads a set of data into a .NET recordset.
After that, inmediately flow execution goes to For..Each Loop. I'd like to avoid go in that direction when Data Flow returns zero rows.

How can I do such thing?

I've tried this on Precedence Constraint Editor but it doesn't work..It doesn't recognize EOF keyword..

@[User::ResulSet] == EOF


Thanks in advance for your input,

Enric

Need To Avoid Repeated Data In A DataGrid

Apr 15, 2004

Hi there :)

I am developing a system for my uni course and I am stuck a little problem...

Basically its all about lecturers, students modules etc - A student has many modules, a module has manu students, a lecturer has many modules and a module has many lecturers.

I am trying to get a list of lecturers that run modules associated with a particular student. I am able to get a list of the appropriate lecturers, but some lecturers are repeated because they teach more than one module that the student is associated with.

How can I stop the repeats?

Heres my sql select code in my cs file:

string sqlDisplayLec = "SELECT * FROM student_module sm, lecturer_module lm, users u WHERE sm.user_id=" + myUserid + "" + " AND lm.module_id = sm.module_id " + " AND u.user_id = lm.user_id ";
SqlCommand sqlc2 = new SqlCommand(sqlDisplayLec,sqlConnection);
sqlConnection.Open();
lecturersDG.DataSource = sqlc2.ExecuteReader(CommandBehavior.CloseConnection);
lecturersDG.DataBind();

And here is a pic of my Data Model:
Data Model Screenshot

Any ideas? Many thanks :) !

How Can Avoid Displaying Data Using A Cursor ??

Oct 16, 1998

I defined a stored procedure with a cursor inside for updating data.
When I call it from an MSAccess client, it fails.
When I execute it directly in a ISQL/w windows, it doesn`t fail but it displays me the data (wich is the reason for failing from MSAccess).
Do somebody know if I could do it without displaying data in the screen ??

Massive Data Import, How To Avoid Dublicates?

Dec 4, 2006

Hello,

I am currently working on a project where I have to import a huge amount of data from CSV files into a database.
I don't want to have dublicate keys in my table, but my CSV file contains them. That means the line more at the end of the file contains the mor up to date information that I have to store.

I try to fix this problem since serveral weeks, but my algorithm is very slow and blocks all other processes on the server. At the moment I am copying all records into a temp table that occure more than once in the CSV file. After that I am running through this table line by line and check if the key already exists in the target table and then either make an insert or an update.

Does somebody know a better process?

I hope somebody can help me... :(

Avoid Cross Database Views In Data Warehouse

May 4, 2007

We have a relational database (rd) and a data warehouse (dw). This dw has a table (tw) with all key fields (dimension keys) and metric related (measures) fields. This table is populated with monthly data each month. The tw is joined to various look up views present in the dw to obtain name fields from rd. The DBA wants me to remove the look up views. I now have following 2 options that I can think of –

1)Further de-normalize the tw and store the name fields as well. However, there are two issues with this option –

a.The size of tw will grow tremendously.
b.We are storing monthly data and the values in the name fields may change after some time. Then we will have to put in additional views/objects to obtain the latest name.

2)Using ETL, obtain the copy of rd tables overnight in dw. We will then join tw with these tables and there will no longer be cross database joins. However, this will be a burden on maintenance and support.

As of now these are the possible options I can come up with. Which one would you suggest and why? If you have another option, please let me know.

Thank you all in advance,

How Can We Avoid Somebody To Access The MDF Data By Doing User Instance Connection?

Dec 11, 2006

I created a database that will be distributed to my customers. This database is running on an Instance of SQL Server 2005 Express edition. I removed the admin logins from my SQL Server Instance so in theory, only my application connecting itself using the Sql Server autenthication will be able to be access the data (using "sa" having a password that I set at the installation).

For now, all this is working fine and after some tests, I haven't been able to access the data in any ways except by using the "sa" and the password my app is the only one to know.

But the problem is coming from a security leak when using User Instance. Indeed, I've been able to create a program getting the content from my MDF file. If somebody try to get connected using User Instance on his own SQL Server instance, he will be able to reach the data.

How could I prevent this to happend? Is there a property or something that could be set into the database that would prevent the database (mdf file) to be used with User Instance?

Thanks!

DB Engine :: How To Avoid Special Characters While Migrating Data

Jun 23, 2015

I have a source sql 2005 with the database collation SQL_Latin1_General_CP1_CI_AS and destination with sql 2012 with the same collation.

But the SQL server llvel collation is different, sql 2005 uses Latin1_General_CI_AI and sql 2012 uses "SQL_Latin1_General_CP1_CI_AS"

Now when i load the data from 2005  for one table to sql 2012 i could see special characters in one column. And i dont see that in the source database. Is there a way to avoid that or is it something we need to manually fix.

To Avoid Fragmentaion

Jun 25, 2001

I found some fragmented data pages in my database tables.
I have found out using DBCC Showcontig commands.
I want to remove data fragmentation.
My tables are replicated. Is it possible to remove fragmentation
without using export and import. Please help me in fixing this problem.

Is there any way to fix replication failure with out recreating it.
My replication has failed saying is timout error.error is could not connect
subscriber. But I can able to ping the subscriber and if I create a new publisher and subscriber it is working fine. But existing one is not working.
What might be the possible reason. We have recreated the replication. We droped the existing one and recreated it. It took around 14 hours to sync.
Is there any way to resync with out recreate publication. We are using transaction replication and merge replication.

To Avoid Looping

Nov 16, 2005

Hi All,

Very Ad-hoc requirement I am having.

I've got one table with two columns.
Column Name Data Type
1) Id Integer Identity
2) RemDate DateTime

I've to write one SP/JOB in that there will be an integer input parameter @numofday.

Say value of @numofday is 5 then.... in SP/Job I need to insert 31 - 5 = 26 records to above-mentioned table where date starting from 1st of current month.

This logic can be achieve through looping but if anyone can suggest some better way to achieve this functionality without use of looping.

Thanks in advance,

Trying To Avoid A Cursor...

Jan 13, 2006

Happy new year to all! Now a question...

I added a new column to StagePayments table - Activity - which is supposed to end up being the same as the JobActivityID from the JobActivities table. Basically, I need to get JobActivities (JA) info and put it in the StagePayment (SP) column. Problem is there are duplicate JA/Descriptions and SP/Activities, so what I need is to take the first sequence SP/Activity and grab the first JA/JobActivityID that matches for a particular JobID. Then get the next one of each and so on and so on...

way too basic as I get this error...

Subquery returned more than 1 value. This is not permitted when the subquery follows =, !=, <, <= , >, >= or when the subquery is used as an expression.

I know somehow I have to get the duplicate Activities in the same sequence as the Descriptions, but that's where I'm stuck?!?

If anyone is able to offer suggestions on how to get this to update correctly, I'd be very happy to hear about it!
Thanks in advance!

Would Like To Avoid Cursor, Please Help

Sep 28, 2006

Hi,

I need to query a database for a recordset and insert this into another database row-by-row.

For each record I want to provide a time of insert, but for each insert this time has to be incremented by 1, the time format is HH:MM:SS.0000 so for each inserted record the last decimal point would increment by 1.

Can I do this without a cursor ?

Any additional info I will provide gladly.

Thanks!

How To Avoid Deadlocks

Mar 19, 2004

I am conducting stress testing for my website and keep getting deadlocks with the following message when one process is adding about 100 records per second and another process is trying to access the data:

Transaction (Process ID 499) was deadlocked on lock resources with another process and has been chosen as the deadlock victim. Rerun the transaction.

What do I need to do in my stored procedures to avoid this? I only have ONE stored prcoedure that locks a row while incrementing an ID value. I am not doing any other locks, so is this a SQL Server system lock?

Any advise would be much appreciated. Thanks!

I Want To Avoid Using A Cursor, Please!

Jul 23, 2005

Application is a Work Tracking/Timesheet database.The increments of work are stored in the TimesheetItem table. Thiscontains, inter alia, the Work Code, the Start and the Duration thatthe employee spent that day on a particular project.Some employees in the Network Support Department don't complete astandard 7.5 hour day for various reasons, so for every Network Supportperson I need to update these particular days with an amount to bringthe total day's hours to 7.5.This SQL will get me a list of all TimesheetItem records for thepersonnel concerned.SELECTTimesheetItem.TypeID,[Work].WorkCode,TimesheetItem.Start AS Start,SUM(CAST(TimesheetItem.DurationMins AS float) / 60) AS HoursFROMTimesheetItem LEFT OUTER JOIN[Work] ON TimesheetItem.WorkID = [Work].WorkIDWHERE(TimesheetItem.EmployeeID IN(SELECT EmployeeID FROM Employee WHERE DepartmentID = 2))GROUP BYTimesheetItem.TypeID, TimesheetItem.Start, [Work].WorkCodeHAVING(TimesheetItem.Start >= @FromDate) AND (TimesheetItem.Start <= @ToDate)ORDER BYTimesheetItem.StartWhat I need is to group these records by EmployeeID where theaccumulated hours per day are < 7.5, so that I can then insert anincrement to make up the difference.I'm writing this from home and I don't have access to the tables toprovide a script, but there's nothing untoward there.Hope someone can help!ThanksEdward

How To Avoid A Growing Transaction Log

Mar 12, 2003

I have to admit, I'm usually using the MySql database, but in this particular case I have to use MSSQL 2000.

Over to my problem.

I'm building a web-based system (who isn't these days) in which the user types arbitrary information that is published when the user pushes the save button. Nothing new about that.

Here comes the tricky part, when the user wants to edit an existing item I copy all information in the database and sets the id of the 'edit-copy' to the negative value ( id 45 becomes id -45 for the edit-copy). This is also done on all items in other tables that is connected to the main item.

This way I get a copy that the user may edit without messing up the published information. When the user is done I either delete all the negative items (cancel) or delete the positive items and update the negative to become positive (save).

So far so good, allmost... my problem is that the transaction log grows tremendously.

Is there any other way to accomplish a safe edit that doesn't affect the transaction log as much as my current solution?

Could I be doing something wrong when updateing or deleteing my items?

Avoid Sql Class 2733a

Jun 27, 2005

hate to gripe, but this was bad. I have taken several sql server classes over the years, and have always been happy with the class, but avoid the 2733a (upgrading you database administration skills to sql 2005). Class is poorly devloped and incomplete. Half of the examples were to do things such as mirroring and replication from a command prompt. I thought I was in an Oracle 8 class. It was clear much of this functionality is not complete. In fact most of the class was command prompt based. They had absolutley nothing about the upgrade process from SQL 2000 to SQL 2005. I hope MS is not taking a step backwards, I always thought the strong suite for MS was the enterprise manager tool suite. The instructor did tell me there was an upgrade to the class that just came out, but it has a long way to go.

Avoid Increasing The Log File

Jan 26, 2004

Hello All,

I have faced a network problem during some days, what forced one of our replications to be stopped.
The Publisher database is a high volume database.
After I re-started the replication, the Subscirber database has its transacting log size increased quickly, because of the high volume of information to be inserted.

My concern is the way it is working, there will be no enough space for the log or for its backup files.

So, I have created a TSQL job within the following commands:

BACKUP LOG database_name
WITH TRUNCATE_ONLY
DBCC SHRINKDATABASE (database_name,TRUNCATEONLY)

It's running every 20 minutes, however the transaction log remains increasing.

I have also changed the db_option "SELECT INTO/BULKCOPY" to TRUE, in order to avoid logging bulk copies, but I believe, it didn't work because it didn't apply to replication process.

Does Anybody know if I can disable the transaction log or avoid this incresing of size during the replication?

Thanks a lot!

How To Avoid Divide By Zero Error

Nov 6, 2013

I have some SQL scripts for SQL Views and getting divide by zero error. I am using

COALESCE(Field1,Field2,1)/COALESCE(Field3,Field4,1)

This function can avoid NULL but how I can avoid 0 ?

Is there any function in SQL that can take care both NULL and 0 and replace it with 1.

Query To Avoid Certain Rule

Jun 16, 2014

I have a query that maps all products to some customer levels. In this case levels 0,5,7 and 8

DELETE FROM ProductCustomerLevel
WHERE CustomerLevelID IN (0, 5, 7, 8)
INSERT ProductCustomerLevel
(
ProductID,
CustomerLevelID

[Code] ....

Basically this maps all products in a database to these customer levels so that they get a discount.

I know need to create a new customer level, example number 9. These will only have 1 or 2 products applied to it.

How can I change the SQL above so that it does not map those products already in Customer Level 9 to levels 0,5,7 and 8

Want To Avoid Cursors ... Need Help With Query

Oct 30, 2006

Hi,

I have a customer who is using vba to pull a result set from an sql server stored procedure into excel. She wants a calculated column added to the result set that gives:
The number days (datediff) between the end date (autend_dte) on one row and the begin date (autbeg_dte) on the next row for each client (clt_num). The rows are to be ordered by client and begin date. The number should be associated with the second row used to calculate the date diff. The first row for each client will have a date diff of 0.

I could do this using a cursor in the stored procedure or a loop in the vba, but I would prefer to do it with the select, but I don't even know where to start.

See expected results below.


CREATE TABLE #testit (
clt_num int NOT NULL ,
autbeg_dte datetime NULL ,
autend_dte datetime NULL)

INSERT INTO #testit (clt_num, autbeg_dte, autend_dte)
SELECT 510, '2004-09-01 00:00:00.000', '2005-09-30 23:59:00.000' UNION ALL
SELECT 510, '2005-10-01 00:00:00.000', '2006-04-06 23:59:00.000' UNION ALL
SELECT 600, '2006-08-01 00:00:00.000', '2006-11-06 23:59:00.000' UNION ALL
SELECT 2529, '2006-01-13 00:00:00.000', '2006-04-11 23:59:00.000' UNION ALL
SELECT 2529, '2005-11-30 00:00:00.000', '2005-12-12 23:59:00.000' UNION ALL
SELECT 2602, '2006-03-29 00:00:00.000', '2006-05-02 23:59:00.000' UNION ALL
SELECT 2602, '2005-11-12 00:00:00.000', '2006-02-27 23:59:00.000' UNION ALL
SELECT 2602, '2006-05-26 00:00:00.000', '2006-06-12 23:59:00.000' UNION ALL
SELECT 2602, '2006-06-18 00:00:00.000', '2006-06-28 23:59:00.000'

SELECT * FROM #testit
order by clt_num,autbeg_dte

Expected result:
