• Query Execution Plan - When is the Where clause executed?

  - by Alex

  I have a query like this (created by LINQ): SELECT [t0].[Id], [t0].[CreationDate], [t0].[CreatorId] FROM [dbo].[DataFTS]('test', 100) AS [t0] WHERE [t0].[CreatorId] = 1 ORDER BY [t0].[RANK] DataFTS is a full-text search table valued function. The query execution plan looks like this: SELECT (0%) - Sort (23%) - Nested Loops (Inner Join) (1%) - Sort (Top N Sort) (25%) - Stream Aggregate (0%) - Stream Aggregate (0%) - Compute Scalar (0%) - Table Valued Function (FullTextMatch) (13%) | | - Clustered Index Seek (38%) Does this mean that the WHERE clause ([CreatorId] = 1) is executed prior to the TVF ( full text search) or after the full text search? Thank you.

• Is there a command to test an SQL query without executing it? ( MySQL or ANSI SQL )

  - by Petruza

  Is there anything like this: TEST DELETE FROM user WHERE somekey = 45; That can return any errors, for example that somekey doesn't exist, or some constraint violation or anything, and reporting how many rows would be affected, but not executing the query? I know you can easily turn any query in a select query that has no write or delete effect in any row, but that can lead to errors and it's not very practical if you want to test and debug many queries.

• How to use multiple identity numbers in one table?

  - by vincer

  I have an web application that creates printable forms, these forms have a unique number on them, the problem is I have 2 forms that separate numbers need to be created for them. ie) Form1- Numbered 2000000-2999999 Form2- Numbered 3000000-3999999 dbo.test2 - is my form information table Tsel - is my autoinc table for the 3000000 series numbers Tadv - is my autoinc table for the 2000000 series numbers What I have done is create 2 tables with just autoinc row (one for 2000000 series numbers and one for 3000000 series numbers), I then created a trigger to add a record to the coresponding table, read back the autoinc number and add it to my table that stores the form information including the just created autoinc number for the right series of forms. Although it does work, I'm concerned that the numbers will get messed up under load. I'm not sure the @@IDENTITY will always return the right value when many people are using the system. (I cannot have duplicates and I need to use the numbering form show above. See code below. ** TRIGGER ** CREATE TRIGGER MAKEANID2 ON dbo.test2 AFTER INSERT AS SET NOCOUNT ON declare @someid int declare @someid2 int declare @startfrom int declare @test1 varchar(10) select @someid=@@IDENTITY select @test1 = (Select name1 from test2 where sysid = @someid ) if @test1 = 'select' begin insert into Tsel Default values select @someid2 = @@IDENTITY end if @test1 = 'adv' begin insert into Tadv Default values select @someid2 = @@IDENTITY end update test2 set name2=(@someid2) where sysid = @someid SET NOCOUNT OFF

• How to parse a date from an SSIS Excel filename

  - by user327045

  I want to use the foreach container to iterate through a folder matching something like: "Filename_MMYYYY.xls". That's easy enough to do; but I can't seem to find a way to parse the MMYYYY from the filename and add it to a variable (or something) that i can use as a lookup field for my DimDate table. It seems possible with a flat file data source, but not an excel connection. I'm using Visual Studio 2005. Please help!

• Figuring out the resource a lock in SQL Server 2000 affects

  - by Michael Lang

  I am adding a simple web-interface to show data from a commercial off the shelf (COTS) application. This COTS issues locks on any record the user is actively looking at (whether they intend to edit and update it or not). I have found sp_lock and the Microsoft sp_lock2 scripts and can see the locks, so that's all well and good. However, I cannot figure out how I can tell if a specific record I am about to update has been affected by one of these locks. If I submit the update request and there is in fact a lock, the web-interface will wait indefinitely until the user closes the window in the COTS. How can I either: a) determine before issuing an update that the record has been locked OR b) issue an update that will immediately return with a LOCKED status rather than indefinitely waiting on the COTS user to close their window on that record?

• Use a SELECT to Print a Bunch of INSERT INTOs

  - by Mikecancook

  I have a bunch of records I want to move to another database and I just want to create a bunch of inserts that I can copy and paste. I've seen someone do this before but I can't figure it out. I'm not getting the escapes right. It's something like this where 'Code', 'Description' and 'Absent' are the columns I want from the table. SELECT 'INSERT INTO AttendanceCodes (Code, Description, Absent) VALUES (' + Code + ',' + Description + ',' + Absent')' FROM AttendanceCodes The end result should be a slew of INSERTS with the correct values like this: INSERT INTO AttendanceCodes (Code, Description, Absent) VALUES ('A','Unverified Absence','UA')

• Oracle SQL outer join query puzzle

  - by user1651446

  So I am dumb and I have this: select whatever from bank_accs b1, bank_accs b2, table3 t3 where t3.bank_acc_id = t1.bank_acc_id and b2.bank_acc_number = b1.bank_acc_number and b2.currency_code(+) = t3.buy_currency and trunc(sysdate) between nvl(b2.start_date, trunc(sysdate)) and nvl(b2.end_date, trunc(sysdate)); My problem is with the date (actuality) check on b2. Now, I need to return a row for each t3xb1 (t3 = ~10 tables joined, of course), even if there are ONLY INVALID records (date-wise) in b2. How do I outer-join this bit properly? Can't use ANSI joins, must do in a single flat query. Thanks.

• Trigger on database using a web application and a winform application

  - by Michael

  Hello all, Situation: I have a web application which shows errors and where you can accept those error messages. I also have a service, which checks errors from a system and sets the error messages in the database. When I accept an error in the web application, i would like the service to know which error message has been accepted, so that it can do some other actions. My guess is that this could be done through some sort of trigger, but i can't figure out how. Can anyone help me with this?

• Populating a WPF listbox with items from an SQL (SDF) database

  - by xplinux557

  I have been searching on how to do this for a very long time, and I have not managed to get a straight answer on the subject, so hopefully one of you StackOverflow users will be able to help me here. I have a WPF ListBox named CategoryList and a SDF database called ProgramsList.sdf (with two tables called CategoryList and ProgramsList). What I wish my program to do is get the category names from the CategoryList table and list them in the ListBox control called CategoryList. Here's the code that I tried, but it only caused my program to crash. SqlConnection myConnection = new SqlConnection("Data Source=" + AppDomain.CurrentDomain.BaseDirectory + "ProgramsList.sdf"); SqlDataReader myReader = null; myConnection.Open(); CategoryList.Items.Clear(); SqlDataReader dr = new SqlCommand("SELECT Name FROM CategoryList ORDER BY Name DESC", myConnection).ExecuteReader(); while (myReader.Read()) { CategoryList.Items.Add(dr.GetInt32(0)); } myConnection.Close(); Can anyone help me? Thanks in advance!
