I have a database with three different tables having the exact same fields. New records are written to table1, before moving to table2 and ultimately table3. I was wondering if it's possible to run the same query on all three tables at the same time. I need to get all unique instances in the JC field from each table after a specified date. I get an "Ambiguous column name" error on the JC and TimeID fields.
SELECT distinct [JC]
FROM [table1], [table2], [table3]
where timeid > '20090900';
I have two different tables... one for all Staff, and another for all Temp Staff. I need both to output to a datagrid, and so I need to grab both tables from a SQL query to output to my datagrid, but I can't seem to get the logic right for it to work. Can someone give me some suggestions on why my results are blank when I'm running this query? I thought a simple join would allow both sets of identical column names to coexist in peace...SELECT TOP 100 PERCENT dbo.StaffDirectory.UserName, dbo.StaffDirectory.LastName, dbo.StaffDirectory.FirstName, dbo.StaffDirectory.Dept, dbo.StaffDirectory.Title, dbo.StaffDirectory.EMail, dbo.StaffDirectory.LocationFROM dbo.StaffDirectory INNER JOIN dbo.TempStaff ON dbo.StaffDirectory.Location = dbo.TempStaff.Location AND dbo.StaffDirectory.EMail = dbo.TempStaff.Email AND dbo.StaffDirectory.Title = dbo.TempStaff.Title AND dbo.StaffDirectory.Dept = dbo.TempStaff.Dept AND dbo.StaffDirectory.FirstName = dbo.TempStaff.FName AND dbo.StaffDirectory.LastName = dbo.TempStaff.LName AND dbo.StaffDirectory.UserName = dbo.TempStaff.UName AND dbo.StaffDirectory.MDNo = dbo.TempStaff.MDNoIs something wrong here? It just doesn't work =(Any suggestions would be really appreciated.Thank you
Hi, I have two tables named Tab1 and Tab2. Both are identical in structure. The only diff is Tab2 has two more additional fields (FromDate and ToDate). The structure is like below : Col1 Col2 (Date field) Col3 Col4
Also Tab 2 have Col5 (From Date) Col6 (To Date)
Now I want to transfer some set of reocrds from Tab1 to Tab2. The additional Tab2 field (Col5 and Col6) values should be the minimum and maximum values of Tab1 date field for the current set.
How to accomplish this? Kindly help me in this regard.
Does anyone have a good query that would return records from two tables that are found in one, but not it the other table? In my situation I have 2 tables that are duplicate tables and I need to find an additional 3000 records that were added to one of the tables. I also have a composite key so the query would have col1, col2 and col3 as the composite key. So far I have tried concatenating the 3 columns and giving the result an alias and then trying to show the ones that were not in both tables, but have been struggling. Thanks..
I'd like to extend a package functionality. I created it drag/drop way with hard-coded table names.
Now for the same source and destination connections I'd like somehow in a loop transform 20 source tables of the same structure to 20 destination tables of the same structure providing table names in a loop. I also have in the package preparation SQL tasks such as dropping destination table if exists, and then re-creation , so it needs to consume a table name as parameter from my loop.
Im wondering if it is possible to write a procedure that check two identical tables for any missing records. The table design is excatly the same, but some records (of the 40,000) have not copied over to the second table.
We have written an application which splits up our customers data intotheir individual databases. The structure of the databases is thesame. Is it better to create the same stored procedures in eachdatabase or have them in one central location and use the sp_executesqland execute the generated the SQL statement.Thank you.Mayur Patel
I'm trying import 7 tables from each of 30 SQL2005 databases into a SQL2005 Consolidation database. I can simply create data flow tasks for each one but instead I would like loop through a list instead.
I've created a table to house the names of the databases from which I want to import the data. I've created SQL task to return the database names from the table as a "Full Result Set". I've assigned the result set to a user variable (type = Object) an named the result name 0
What I'd like to do is create a data flow task which connects to each of the databases and imports 7 specified tables from each database appending the table name with my database name in the result set.
I'm stuck on how I'd set the connection strings in my OLE DB Source in my Data Flow task. Any insight would be greatly appreciated.
Sorry if this is a super-basic question...I'm used to join selects but not sure how to approach an append select (or something like it) I have two tables with identical field structures: a Master table with 10,000 rows and a Custom table table with 1,000 rows To keep it simple, let's say the two tables each have a FirstName field and a LastName Field. Is it possible to use a View or a Select statement (or any other method) to 'append' the rows of both tables so that the result set still has only the two columns (FirstName and LastName) and has 11,000 rows? Thanks for your help! Randy

Hello Everyone,I have a very complex performance issue with our production database.Here's the scenario. We have a production webserver server and adevelopment web server. Both are running SQL Server 2000.I encounted various performance issues with the production server with aparticular query. It would take approximately 22 seconds to return 100rows, thats about 0.22 seconds per row. Note: I ran the query in singleuser mode. So I tested the query on the Development server by taking abackup (.dmp) of the database and moving it onto the dev server. I ranthe same query and found that it ran in less than a second.I took a look at the query execution plan and I found that they we'rethe exact same in both cases.Then I took a look at the various index's, and again I found nodifferences in the table indices.If both databases are identical, I'm assumeing that the issue is relatedto some external hardware issue like: disk space, memory etc. Or couldit be OS software related issues, like service packs, SQL Serverconfiguations etc.Here's what I've done to rule out some obvious hardware issues on theprod server:1. Moved all extraneous files to a secondary harddrive to free up spaceon the primary harddrive. There is 55gb's of free space on the disk.2. Applied SQL Server SP4 service packs3. Defragmented the primary harddrive4. Applied all Windows Server 2003 updatesHere is the prod servers system specs:2x Intel Xeon 2.67GHZTotal Physical Memory 2GB, Available Physical Memory 815MBWindows Server 2003 SE /w SP1Here is the dev serers system specs:2x Intel Xeon 2.80GHz2GB DDR2-SDRAMWindows Server 2003 SE /w SP1I'm not sure what else to do, the query performance is an order ofmagnitude difference and I can't explain it. To me its is a hardware oroperating system related issue.Any Ideas would help me greatly!Thanks,Brian T*** Sent via Developersdex http://www.developersdex.com ***
I have a Client-Server - App where every Client-User has his own DB. The server is monitoring changes to all Client-DB's via SqlDependency. My problem can be reproduced with a small application, it even might be a €śfeature€? and not a €śbug€?:
- Consider two Databases TestDb1 and TestDb2 running on one SQL Server 2005 instance.
- Both DB€™s have identical Schemas.
- Consider the two DB€™s have each one table named €śTable1€?.
- Both tables have the same schema as already mentioned (the fields Id and Text).
- Now I setup a SQLDependency object on each Database:
dependency.OnChange += new OnChangeEventHandler(dependency_OnChange);
}
}
If I make any changes to the Table in TestDb1 I get two notifications with the different Id€™s but the same Info,Source,Type (saying e.g. Data,Change,Update). If I make changes to the Table in TestDb2 I again get two notifications with the same result. As soon as I rename the Table in one of the Db€™s (e.g. Table2) and also change my Sql-Query in the code €“ I get just one Notification as expected. This behaviour is the same even If I change the connectionstring so that it points to another machine. So it somehow seems to fire a notification for every change to a table with the same name €“ regardless of the connectionstring where the physical change was done.
Does anybody know if this is a wanted behaviour of SqlDependency ? Does anybody know how I can set this up so I can have two DB€™s with identical Schemas and only get a Notification from the DB I actually changed ?
Hello,I ended up with two identical rows in one table. They should have differences but I cannot update one, as it tries to update both of them, or throws an error. How to update only one row, and leave other as is?
Here's some code that says it should identify if a user already exists in my database. I have changed the code to match my database, but it seems to have somewhat the opposite affect, rejecting all names (even new ones) or accepting all names (including existing ones). The switch in situations occurs in the "if" statement towardsd the end, when I change the sign of objDR.RecordsAffected. Do you have any idea what could be wrong? Thanks. Function DoesUserExist(ByVal userName As String) As Boolean Dim connectionString As String = "server='(local)Netsdk'; trusted_connection=true; Database='AuthorizedUsers'" Dim sqlConnection As System.Data.SqlClient.SqlConnection = New System.Data.SqlClient.SqlConnection(connectionString)
Dim queryString As String = "SELECT [Users].[UserName] FROM [Users] WHERE ([Users].[UserName] = @UserName)" Dim sqlCommand As System.Data.SqlClient.SqlCommand = New System.Data.SqlClient.SqlCommand(queryString, sqlConnection) Dim Cmd as New SQLCommand(queryString, sqlConnection) With Cmd.Parameters .Add(New SQLParameter("@username", username)) End With
sqlConnection.Open Dim blHasRows As Boolean Dim objDR As System.Data.SqlClient.SqlDataReader = Cmd.ExecuteReader(system.data.CommandBehavior.CloseConnection)
if objDR.RecordsAffected > 0 then blHasRows="True" else blHasRows="False" End If
How can I create a table identical to another one? I need to copy the indexes a constraint too. Example: I have a table "employee" and I want another table "employee2" with the same indexes and primary key and references.
I'm using a query to see how many times an action was recorded on a person. The query works, it returns this:
John Smith 1 John Smith 1 John Smith 1 Jane Doh 1 Jane Doh 1 Al Johnson 1
but I need it to return totals like this
John Smith 3 Jane Doh 2 Al Johnson 1
This is the query I am using:
Select Player.First_Name, Player.Last_Name, COUNT(Action.Employee_ID) from Player INNER JOIN PlayerVisit on PlayerVisit.Player_ID = Player.Player_ID join Treatment on Treatment.Visit_ID = PlayerVisit.Visit_ID join Action on Treatment.Action_ID = Action.Action_ID group by Player.First_Name, Player.Last_Name, Action.Employee_Id;
I have implemented a script to perform a MD5 hash on each row processed by the SSIS package so that it can be compared with a stored value to see if there has been a change in the record. This package processes over 1 million rows. In 12 of these rows I get a hash value that is different than the stored value despite the fact that the rows "look" identical. Curious about this, I used the both the CheckSum and Binary_Checksum feature from t-sql to check the rows and they both show the identical checksum value. I have exported the rows into text and did a compare and the records are identical. I assume there must be some hidden characters that is causing the hash to be different, has anyone else run into this issue? Any help is much appreciated.
i created a simple table to record all uploaded files to my website. now, it works, but the problem is, it posts to the table 2 times, as in it executes "Button1_Click" event twice. The result is i get two records which are the same, and only differs in primary key (because i set it as an autonumber). how do i fix this? thanks in advance here's the code: HTML: <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConflictDetection="CompareAllValues" ConnectionString="<%$ ConnectionStrings:ConnectionString %>" InsertCommand="INSERT INTO [Base_Files] ([User_ID], [Date_Posted], [File_Type], [File_Size], [File_Name], [File_Description]) VALUES (@User_ID, @Date_Posted, @File_Type, @File_Size, @File_Name, @File_Description)">
I have an "insert into" statement that creates two identical rows in a table, with this statement: delete from [table] where [column] = @parameterINSERT INTO [table]([fields]) VALUES ([parameter values]) This is the code-behind that performs the insert: Dim dbConn As New SqlConnection(strConn)Dim cmd As New SqlCommand("sp_CreateUser", dbConn)cmd.CommandType = Data.CommandType.StoredProcedurecmd.Parameters.AddWithValue("@UserID", strUserID)cmd.Parameters.AddWithValue("@UserName", strUserName)cmd.Parameters.AddWithValue("@Email", strEmail)cmd.Parameters.AddWithValue("@FirstName", strFirstName)cmd.Parameters.AddWithValue("@LastName", strLastName)cmd.Parameters.AddWithValue("@Teacher", strTeacher)cmd.Parameters.AddWithValue("@GradYr", lngGradYr)Using dbConndbConn.Open()cmd.ExecuteNonQuery()dbConn.Close()cmd.Dispose()dbConn.Dispose()End Using I wonder if it inserts twice due to a postback issue. Is there a way to stop two rows from being created in the first place with the same "insert into" statement? I'd appreciate any advice.
We have MSSQL 2000 Server instance installed and working well on Windows 2003 Server machine [IBM X series-366] with 16GB RAM, 3.67GHZ cpu power, and 400GB hard disk space.
We further created an identical server instance on a new machine. More specifically, on Windows 2003 Server machine [Intel (R) Xeon (TM)] with 16GB RAM, 3.67GHZ cpu power, and 400GB hard disk space, we installed MSSQL 2000 Server and copied over all the dbs, applications ...
We were expecting same or similar performance (since processor speed, ram, hd, server and database configurations are all the same, with same indexes on same tables. However, for some reason, there is a noticeable difference in performance.
More specifically, I ran Profiler for 30 minutes on both servers simultaneously [same trace parameters]. The trace file of the new server is 3 times as large as that of the old one (i.e. It looks like more items are being processed). However, the average duration of the executed stored procedures is much longer on the new server than that of the old server.
Moreover, when I run same queries on 2 servers. The query on the new server always takes longer than that on the old server. And for tables where we don't have indexes, it takes much longer.
Following advice here(http://support.microsoft.com/kb/274750/), we configured our new server (just as was our old one configured) to use 15GB of RAM. I further compared the configurations of 2 servers by executing sp_configure (with advance options). The only difference I saw was that "remote proc trans" is set to off on the new server and on on the old server. I don't think it could affect this issue though.
Furthermore, the new server appears to have many more locks, as compared to the old server. Could it be because it is processing more items?
I cannot figure what is causing the queries to be slower on the new server.
Just setup SSRS and at the stage of generating the model. The error message "ParentKey and ChildKey are identical" is displayed when generating the model if the connection string contains the initial catalog specifier.
Here's what I'd like to be able to do: I have a queue that holds any number tasks, so something like this here:
queue_1 task_a
task_b task_c task_d
Workers are assigned to teams, Red team, Blue team, Green team. What I need to do is identify instances where all tasks for a given queue have been handled by one team. Once a task has been assigned to a queue any team can work on it, but when only one team has completed every task in a queue a bonus should be awarded.
I'm looking for this to award a bonus: queue_num task_num team queue_1 task_a red task_b red task_c red task_d red
No bonus for any team here queue_num task_num team queue_1 task_a red task_b blue task_c red task_d green
So the red team earns a bonus. Now, I have thousands of queues each containing any number of tasks. Using T-SQL how can I find all queues where only one team was responsible for completeing every task assigned to the queue? Do I have to use a cursor and eval each task coming through or is there a faster, more efficient way to handle this in SQL?

Hello,I have this peculiar problem concerning MS SQL Server.My company works with an mailing application (ASP) which uses SQLServer as it's repository. What I want to do is send data directlyfrom my own application to this SQL Server in order to feed themailing application.To test if this was possible I linked the tables from SQL Server in MSAccess and entered the data. This worked fine and the data was pickedup correctly by the mailing application.The problem occurs when I send the data from my application (Javaapplication with JDBC connection). The data is in this case no longerpicked up by the application. The strange thing is that the data whichis entered through Access and the data from the Application lookidentical in de database view. The problem also occurs when the datais send with the tool winSQL and when I view the data in here it stilllooks identical.Even more strange is when I select the record which is not working inAccess and copy it into a new record (only changing the key) itsuddenly works!Has anyone have an idea how this can be?Thanks in advance,Sander Janssen.
I am having trouble with a select statement where i try to use a variety of methods on two columns in different tables that, hypothetically, have exactly the same contents.
Below are the three Create Table statements, so you can see how everything is set up. The columns zone_monthly.specific and #temp_dec0607c.specifics come from almost the same original source, so I can't fathom how they could actually be different in their contents - I know some of the individual lines are the same.
Create Table category_specifics (ID integer, segment nvarchar(Max), specifics nvarchar(max))
BULK INSERT category_specifics
FROM 'c:USERSTEALDOCUMENTShonda_chartsmonthly_filescategory_list.txt'
Create Table zone_monthly (ID Integer, specific nvarchar(max), zone integer, dec06 money, dec07 money)
INSERT INTO zone_monthly (specific, zone)
SELECT specifics, '12' AS zone
From category_specifics
Create Table #temp_dec0607c (ID integer, specifics nvarchar(max), zone integer, dec07 money, dec06 money)
Bulk Insert #temp_dec0607c
FROM 'c:USERSTEALDOCUMENTShonda_chartsmonthly datazonedec0607.txt'
Now here is the SELECT statement that I am having trouble with - It returns no results, and, as I said before, I am rather certain it should return something. I have tried it with an inner join as well (code included), and again, no results.
I am working with a pretty complicated medical XML document and I am trying to query out lab information. The problem I am having is that there are many repeating child nodes and I can’t seem to get all the info I need without creating a bunch of columns. Here is a snippet of the XML; In attempting to shorten it up I may have left some elements unclosed but I hope not create table
I can grab all the lab names alright but I am tiring to also grab the lab components as well. A lab could have just one component or it could have a dozen and I will never know ahead of time how many there are.
The following query works ok but would like to be able to grab all the components for a given lab in one column instead of making several columns incrementing the singleton each time. Is there a way that I can iterate through without creating a bunch of columns?
