Is it possible to reference the data in another field within the same table?
Let's say that one column has a calculation, and a second column has a different calculation. Can the third column find the difference between the first two columns?
(I'm wondering if this is possible to do within the Layout View, not from the Data View)
I have one table name Magazine_Details, it has a composite primary keyCreate table Magazine_Details ( MagazineTitle varchar(60), MagazineType varchar(20), IssueType varchar(25), IssueNumber varchar(10), Qnty int, Qnty_in_Hand int, [Date] datetime constraint PK_Magazine_Details_Composite primary key(MagazineTitle,IssueNumber) ) Another table is Magazine_Issued and i want reference from Magazine_Details table. but i am auable to create foreign key constaraint in Magazine_Issued table.create table Magazine_Issued ( Member_ID varchar(100), MagazineTitle varchar(60) references Magazine_Details(MagazineTitle), IssueNumber varchar(10) references Magazine_Details(IssueNumber), IssueDate datetime, Magazine_Status varchar(10) )
I have a table that contains a Ref field and a TransactionDate field. For each Ref field there are mutliple Transactions. I am trying to put together a query that selects the Latest Transaction date for each Ref field in the table.
I tried:
SELECT * FROM tabMediaTransaction WHERE (TransactionDate = (SELECT MAX(TransactionDate) AS Expr1 FROM tabMediaTransaction AS tabMediaTransaction_1))
But this only returns 1 record for 1 Ref field. I need 1 record for each Ref field
My question is simple, I'd like to do something I do in Jet ANSI-89 SQL. Mind you I'm just adding numbers here - they are not actual columns in 'SomeTable'
SELECT 1 AS A, 2 AS B, A+B AS C FROM SomeTable
The Jet engine evaluates and does arithmetic on the Aliased column names - handy when they contain their own functions. The resultset would show:
A B C 1 2 3
However from what I can tell SQL Server 2005 is not picking this up. Is their an equivalent?
I am trying to eliminate a scalar function by rewriting a view. I currently have a structure similar to the following:
With FirstQuery as (SELECT Trial, SBOI, TBOI, FROM TU WHERE SBOI Between 22000 and 22999 and TBOI < 10000), strt as (SELECT TOP 1 TimeOfEvent, Trial, SBOI, TBOI From TU ORDER BY TimeOfEvent),
[Code] ....
What I trying to do is for the Trial, SBOI, and TBOI in FirstQuery, find the Start Time and Stop Time. TimeOfEvent is an integer in milliseconds. Say I have the following data:
TrialIDÂ Â Â Â SBOIÂ Â Â Â TBOIÂ Â Â Â TimeOfEvent AÂ Â Â Â Â Â Â Â Â Â Â Â 22000Â Â 5000Â Â Â Â Â 5 AÂ Â Â Â Â Â Â Â Â Â Â Â 22000Â Â 5000Â Â Â Â Â 10 BÂ Â Â Â Â Â Â Â Â Â Â Â 22000Â Â Â 5000Â Â Â Â Â 8 BÂ Â Â Â Â Â Â Â Â Â Â Â 22000Â Â 5000Â Â Â Â Â 15
So the DISTINCTÂ output would be:
    Trial    SBOI    TBOI    StartTime    StopTime     A        22000  5000     5                 10     B        22000  5000    8                 15
The problem I am having is that strt is selecting the smallest time period. It doesn't seem to care what the current record in cte is. I thought that by using my joins, it would make it select smallest TimeOfEvent for the Trial, SBOI, and TBOI that are selected in cte. Obviously that is not the case. So, I was trying to add a WHERE to the strt Select Statement such asÂ
WHERE TrialID = FirstQuery.TrialID and SBOI = FirstQuery.SBOI and TBOI = FirstQuery.TBOI but it isn't working either.
I am using vs 2010 to write my dtsx import scripts.I use a script component as a source to create a flat file destination file.Everything have been working fine,but then my development machine crashed and we have to install everything again.Now when i use the execute package utility to test my scripts i get the following error:
Error system.NullReferenceException: Object refrence not set to an instance reference.
In PreExecute section TextReader = new system.io.streamreader(" file name") In the CreateNewOutputRows: dim nextLine as string nextLine = textReader.ReadLine
[code]...
is there something which i did not install or what can be the error?
I have a dataset that sometimes is empty. I have it as a detail row in a table on the report, but since the dataset is null the row does not appear. What I would like to do is have it say "No results" if there are no results, otherwise have it show the results.
I tried to add a textbox and reference the textbox on the table, but it was a no go.
RDL/SRS - Is there a way to tag a reference on a data element?
For example, let€™s say that each data element in column 5 is the result of some equation applied to the elements in columns 1 through 4. The field in column 6 is a function applied to the resulting value from column 5. Is there a way to tag a reference on the column 5 data elements, so they can be referenced from column 6 without reapplying the whole function used to derive column 5 in the first place?
I'm using DTS to import data from an Access memo field into a SQL Server ntext field. DTS is only importing the first 255 characters of the memo field and truncating the rest.I'd appreciate any insights into what may be causing this problem, and what I can do about it.Thanks in advance for any help!
I am attempting to create a program that will run on the PocketPC 2003 environment. I have upgraded Visual Studio to SP1, I have installed SQL Server Compact Edition on my development machine and I have installed SQL Server Compact Edition Tools For Visual Studio on the development machine.
I have created a new project Visual Basic - Smart Device - Pocket PC 2003. I have created a form for user input. I build and deploy the form to the Symbol Pocket PC to test - no connection to data and it works.
I then add a reference to System.Data.SqlServerCE.dll and rebuild and redeploy the application to the handheld. When I attempt to open the form I receive the following error:
at System.Resources.ResourceReader.LoadObjectV2() at System.Resources.ResourceReader.LoadObject() at System.Resources.RuntimeResourceSet.GetObject() at System.Resources.ResourceManager.GetObject() at System.Resources.ResourceManager.GetObject() at pmsPocket.frmSetSOPType.InitializeComponent() at psmPocket.frmSetSOPType..ctor() at System.Reflection.RuntimeContructorInfo.InternalInvoke() at System.Reflection.RuntimeContructorInfo.InternalInvoke() at System.Reflection.ContrcutorInfo.Invoke() at System.Activator.CreateInstance() at MyForms.Create__Instance__() at MyForms.get_frmSetSOPType() at psmPocket.SetSOPType.Main()
Now the confusing part is that I haven't changed any of the forms or the code behind the forms, I have simply added the reference to the project.
Any idea why adding the reference to System.Data.SqlServerCE.dll would cause the system to start generating these errors?
I've checked, the install process has loaded the .NET 2 framework to the handheld. And as indicated at the beginning of this message, the application showed the form prior to my adding the reference.
We have a stock code table with a description field and a brand field - when the data was entered, some of the records were entered with the brand field in the description field.
ie. Code Description Brand ABC1 BLANK DVD SONY ABC2 SONY BLANK DVD SONY
what I need to do is identify where the Brand is in the Description field ...

We migrate data from a legacy system to new system using SSIS. The primary key of legacy system is a user-defined sql server which holds alpha-numeric values. The primary key of new system is a big int(sequential numbers).
When we migrate data, we generate a sequential number for each legacy key(the primary key of legacy data) and insert data in to new system tables. The newly generated sequential numbers and the legacy keys are persisted in an intermidiate table for look up operations of child tables.
We are facing problem when we try to migrate tables which has self referring coulumns. For example a table called Employee has a column ManagerKey which refers to Key column of Employee table. We are struck up in defining data flow tasks to replace legacy ManagerKey column values with the new values(sequential values) generated during the migration process.
We have a Compact Framework 1.1 application that uses Sql Server CE 2.0. In VS2003, a reference to System.Data.SqlServerCe causes the Sql Server CE dlls and Query Analyzer to install to the Emulator or PDA.
I am currently converting the application to Compact Framework 2.0, but we are not upgrading to Sql Server Mobile (yet). However, the reference to System.Data.SqlServerCe, in VS 2005, no longer causes Sql Server CE to install to the PDA/Emulator.
There is a difference in the build outputs between VS2003 & VS2005. In 2003, System_SR_enu.cab, sqlce.wce4.x86.cab & sqlce.dev.wce4.x86.cab are copied & lanuched. In 2005, only System_SR_enu.cab is copied... no launch.
Not a SQL guy but can do enough to be dangerous :)Trying to update a record. We have records that have a field with datasurrounded by some comment text such as *** Previous Public Solution*** Start and *** Previous Public Solution *** End . What I am tryingto do is write a SQL statement that will:Check that field C100 = TICKET0001 (to test with one record beforerunning on whole db)Check that field C101 is = ClosedCheck that field C102 is nullCopy field C103 data to field C102 and strip out any words such as ***Previous Public Solution *** Start and *** Previous Public Solution*** endThanks for any help!Kevin
The logic I am trying to recreate via SSIS is the following SQL statement:
insert into db3.dbo.targettable1 -- Target database table (SiteC, Objecte, Attrib1)
select distinct ?, ?, from ? -- Source database table join dbo.targettable2 c1 -- Target database table on c1.Alias = ? and c1.CSetID = ? and c1.FacID = (select f.PFacID from dbo.Fac f where f.FacID = ?) where not exists (select * from dbo.targettable2 c -- Target database table where c.Alias = ? and c.FacID = ? and c.CSetID = ?)
I have an OLE DB Source that consists of an expression to approximate the following portion of the Above Select statement:
Select ?, from ? -- Source database table and
The package has 2 global variables User:CSetID and User::FacID whose scope is global to the package and whose values are set within a Foreach Loop Container outside of the Data Flow Task
I was trying to reference the 2 global variables within the Looup Transformation to recreate the following portion of the SQL statement.but encounter errors:
join dbo.targettable2 c1 -- Target database table on c1.Alias = ? and c1.CSetID = ? and c1.FacID = (select f.PFacID from dbo.Fac f where f.FacID = ?)
In the Advanced Editor window of Lookup Transaction
select * from (select * from [dbo].[targettable2 ]) as refTable where [refTable].[Alias] = ? and [refTable].[FacID] = ? and [refTable].[CSetID] = ?
Is there away to reference global variables in a Lookup Transformation that are set outside a Data Task Flow?
I have a SSRS 2012 report which references a custom c# assembly.  This report exists in multiple environments (alpha, beta and  production ) which are each associated with different data sources.
Is there a way for the assembly to determine the datasource used by the calling report so it can also connect to it?
Hi,This is driving me nuts, I have a table that stores notes regarding anoperation in an IMAGE data type field in MS SQL Server 2000.I can read and write no problem using Access using the StrConv function andI can Update the field correctly in T-SQL using:DECLARE @ptrval varbinary(16)SELECT @ptrval = TEXTPTR(BITS_data)FROM mytable_BINARY WHERE ID = 'RB215'WRITETEXT OPERATION_BINARY.BITS @ptrval 'My notes for this operation'However, I just can not seem to be able to convert back to text theinformation once it is stored using T-SQL.My selects keep returning bin data.How to do this! Thanks for your help.SD

I have a requirement of table partitioning. we have 10 years of data on a table which is 30 billion up rows on 2005 server we are upgrading it to 2014. we have to keep 7 years of data. there is no keys on table or date column. since its a huge amount of data and many users its slow down the process speed. we are thinking to do partition on 7 years for Quarterly based. but as i said there is no date column on table we have to use reference table to get date. is there a way i can do the partitioning with out adding date column on table? also does partition will make query faster?Â
I have think three ways to do it. 1. leave as it is. 2. 7 years partition on one server 3. 3 years partition on server1 and 4 years partition on server2 (for 4 years is snapshot better?)
I am attempting to create a stored procedure that will launch at report runtime to summarize data in a table into a table that will reflect period data using an array type field. I know how to execute one line but I am not sure how to run the script so that it not only summarizes the data below but also creates and drops the table.
In my SQL Server 2005 database I have created a table with several data fields. One of the fields is designated as a primary key. And another one is just a key. I can easily set the first field as the primary key, but am not able to set the second field as being just a key field. I perform these steps to set the primary key. (1) Right click on the table name and then select 'Open Table Definition' (2) I right click on the field in my data table and select 'Select Primary Key' As I mentioned previously, to set another field up as just a key field, I am not able to do this. My choices are the following when I right click on the data field to be designated as the key field: Set Primary Key, Insert Column, Delete Column,Relationships,Indexes/Keys,Full Text Index,XML Indexes, Check constraints,Properties. None of these choices will allow me to set the field up as a key field. Someone please help me out with this problem.
There has to be a better way (less code) to grab the data in one field than:string sql0 = "Select PSI from agentRate where agent='" + agent + "'"; SqlCommand command0 = new SqlCommand(sql0, conn2);SqlDataReader dr0 = command0.ExecuteReader(); string PSI="";while (dr0.Read()) {PSI = (string)dr0["PSI"]; } dr0.Close();
I recieved a SQL Server table that was supposed to have just the firstname in a field, but actually has firstname and middle name. Example David Michael Carol Anne Is there a way in a query to look for the blank space and separate the names?
I have a field in my table that is varchar:1500:null, but I cannot enter any more that 994 characters. any ideas why?
if exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[Quotes]') and OBJECTPROPERTY(id, N'IsUserTable') = 1) drop table [dbo].[Quotes] GO
ALTER TABLE [dbo].[Quotes] ADD CONSTRAINT [DF_Quotes_Closed] DEFAULT ('N') FOR [Status] GO
CREATE INDEX [idx_RepID] ON [dbo].[Quotes]([RepID]) ON [PRIMARY] GO
CREATE INDEX [indx_CustomerID] ON [dbo].[Quotes]([CustomerID]) ON [PRIMARY] GO
CREATE INDEX [indx_QuoteID] ON [dbo].[Quotes]([QuoteID]) ON [PRIMARY] GO
CREATE INDEX [indx_Status] ON [dbo].[Quotes]([Status]) ON [PRIMARY] GO
[Comment] [varchar] (1500) NULL , is where I can't enter more than 994 characters.
note - I know very little about SQL, I just had the responsibility placed on me at my job. If this is not enough information to go on to throw an idea at me please let me know what else you need.
