Naming Query Column Name Of Resulting Table Name From Query
Oct 23, 2014
I need to name make the name of a column the same as the name of a table from the result of a sql query.. here is the assignment question below..I can't figure out how to get the name of the table to be inputed as the column name..
Write a script that uses dynamic SQL to return a single column that represents the number of rows in the first table in the current database. The script should automatically choose the table that appears first alphabetically, and it should exclude tables named dtproperties and sysdiagrams. [highlight=#ffff11]Name the column CountOfTable, where Table is the chosen table name.[/highlight]
Hint: Use the sys.tables catalog view.
I can figure out the rest. and actually have alredy done it, but i cannot figure out how to do the part that is highlighted above. I looked at lots of things on google to figure it out but no luck..Can some just give me some directlon or an example..
I want to use a Make Table Query to generate a new read-only Table. This I can do but my problem is that I want to be able to name the new Table containing only the records from a calendar year; e.y. Rents2001 and the next year another new table would be created and called Rents2002 and next year Rents2003 ...............
I require the Table to be generated yearly. I know I could do this in other ways but I really require the Table as once I have it I will be doing other things with it to give the final report.
Any suggestions how I can generate the Table with the YEAR being in the Table Name as part of running the Make Table Query? Thanks
have a SQL2K/VB.NET05 -based website that uses a complex search query, whose results will contain additional logic to be evaluated. There are thousands of records and growing, so it is not feasible to code this within the program...it must be evaluated inline or after the query, and it is also not feasible to set up additional fields and tables to handle the logic.
For a very general example: In the .NET code, the following variables are recognized: sex="M" Paid=4350.00 Outstanding=28000.50
One of the query result fields will contain the additional logic to evaluate and another will tell the type of expression..
EVAL EXPR BOOL Sex='F' and Paid/Outstanding < 27.50 BOOL Sex='M' and Paid/Outstanding < 38 or Sex='F' INT Paid*52.33
In other words..the thousands of records being returned have their own additional logic to evaluate. Is there a way this can be done by importing the variable into SQL server and testing it during the query?
If not, is there a way that I can run the code in the middle of .NET? I know I could run scripted code while in ASP, but ASP.NET is compiled, so I dont know if it can be done there....
I have a linked server in SQL 2007 form SQL to DB2.(IBM)
If I write a distributed query from SQL to DB2 I get mt data returned. ie: select * from openquery(Movex_Extranet,'Select * From mvxadta.ooline')
If I write a Query from SQL to DB2 using the 4-part naming convention linkserver.catalog.schema.object then I also get my data returned.
ie: select * from MOVEX_EXTRANET.RCHASE5C.MVXADTA.OOLINE
My problem is with the Query Designer in SQL2007.
When I right click the first lot of code and select "Design query in editor" The Designer GUI opens up and displays my table in graphical form with all columns selected - Great.
But When I repeat this for the code that uses the 4 part naming The Designer opens up and displays the table but with no columns viewable or available for me to select ??
Anyone know what might be causing this to happen. Is it a bug in SQL 2007 ??
I have tried linking the server using 2 types of providers ( One from Microsoft & one from IBM) but each time I still cannot see or choose columns in the designer using the 4part naming convention.
The 2 providers I tried where. Microsoft OLE DB for ODBC Drivers. IBM DB2 UDB for Iseries IBMDA400 OLE DB Provider
Any help greatly appretiated as I would really love to use the designer using 4part naming convention.
Apparently if you read this the it should work ? http://msdn2.microsoft.com/en-us/library/aa225987(SQL.80).aspx#dvmscworkingwithtablesfromdifferentdatasources
tablename/columnname to query the return values.I want to have this query that returns the table names and column names that contain the given value(s). Business needs dictated that I have to start from given values instead. That is to say we own the apps developed by vendors, and own the dbs, but no middle tier code, nor data dictionary.
So, I started with this select distinct object_Name(Object_ID) myTbls, [name] from sys.columns where name like '%mycolname%' and object_Name(Object_ID) not like 'fn%'
I have to guess the possible column name as the starter. I realize if the condition value is not very unique, the return dataset could be huge. It is a performance nightmare and it is useless. So I hope the solution will let me specify, say return the first 1000 matches.
Hi All I want to retrieve the data type of table column and validate the input data whether same as data type of table column before insert into database. Any suggestion? I use asp.net + msde

I have a transaction table (which contains details of all products on all orders) and is have a discrepancies table which includes details on products that couldnt been found (hence error in stock count)...
Now I want to write a query returning details of all products from a specfic orders.. pretty simple
SELECT product, description, qty from TRANSACTIONS where order_no = 'xxx'
but i also want to add an extra boolean column (true if product is in discrepancies table and false if product is not in discrepancies table...will become checkbox at front end)... im not sure how to write this bit....
I know it would a transaction table LEFT JOIN to discrepancies table, but I do not know how to write syntax to add extra column...
I want to get a column count several times in one query using differentfilters but can't work out how to do it - can anyone point me in the rightdirection?For example, how would combine these two selects into one query that willlist the total and filtered actions:SELECT COUNT(actions) as actioncount, locationFROM mytableGROUP BY locationSELECT COUNT(actions) as actioncount, locationFROM mytableWHERE mycondition IS NULLGROUP BY location
I cannot insert into my appointments table because the primary key and identity column, appt_id, cannot be added. What do I have to change in my SQL statement to add new records into this table?

Hi! I am joining 3 tables in SQL , I am getting the results I want exept it's duplicated. So the resultinmg table fom my stored procedure has 3 rows that have the same bulletin. How do I filter the storedprocedure to output only the rows that don't have duplicate entries for the column 'Bulletin' Thanks. Here is my stored procedure:PROCEDURE [dbo].[spGetCompBulletins] @Userid uniqueidentifier OUTPUT,@DisplayName varchar(200)
AS
SELECT * FROM dbo.UserProfile INNER JOIN dbo.bulletins ON dbo.UserProfile.UserId = dbo.bulletins.Userid INNER JOINdbo.Associations ON dbo.Associations.BusinessID = dbo.bulletins.Userid WHERE UserProfile.DisplayName=@DisplayName and Userprofile.Userid = @Userid ORDER BY Bulletins.Bulletin_Date Return
use mysql1 declare @bp xml select @bp=xml ;WITH XMLNAMESPACES('http://schemas.openehr.org/v1' as bp,'http://www.w3.org/2001/XMLSchema-instance' as xsi,'OBSERVATION' as type) select * from ( select m.c.value('(./bp:data/bp:items[1]/bp:value[1]/bp:magnitude)[1]','int') as systolisch from BloodpressureMitSchema cross apply @bp.nodes('/bp:content/bp:data/bp:events') as m(c))m
But with this "cross apply" I can only query all the values in one xml and repeat them. Is there something wrong at "declear"
I have a table with a column AttributeNumber and a column AttributeValue. The data is like this:
OrderNo. AttributeNumber AttributeValue 1.-Order_1 2001 A 2.-Order_1 2002 B 3.-Order_1 2003 C 4.-Order_2 2001 A 5.-Order_2 2002 B 6.-Order_2 2003 C
So the logic is as follows:
I need to display in my query the values are coming from Order_1, means AttributreValues coming from AttibuteNumbers: 2001,2002,2003...and Order_2 the same thing.
Not sure how to create my Select here since the values are in the same table
I have the following problem running an sp with a table variable (sql server 2000) - the error which occurs at the end of the query is: "must declare the variable @THeader" . @THeader is the name of the variable table and the error occurs with such references as @THeader.ApplyAmt, @THeader.TransactionHeaderID, etc.
declare @THeader TABLE ( TransactionHeaderID [int] NOT NULL , PatientID [int] NOT NULL , TransactionAllocationAmount [money] NOT NULL , ApplyAmt [money] NULL ) - create table variable
insert into @THeader select TransactionHeaderID,PatientID,TransactionAllocationAmount,ApplyAmt from mtblTransactionHeader where PatientID = 9 - fill the table variable
UPDATE @THeader set TransactionAllocationAmount = (SELECT isnull(Sum(mtblTransactionAllocation.Amount),0) FROM mtblTransactionAllocation where mtblTransactionAllocation.DRID = TransactionHeaderID or mtblTransactionAllocation.CRID = TransactionHeaderID) from @THeader, mtblTransactionAllocation - do the updates on the table variable
Update @THeader set ApplyAmt = (SELECT mtblTransactionAllocation.Amount FROM mtblTransactionAllocation where mtblTransactionAllocation.DRID = TransactionHeaderID and mtblTransactionAllocation.CRID = 187 and PatientID = 9) from @THeader, mtblTransactionAllocation - do the updates on the table variable
- below is where the problems occur. It occurs with statements referencing columns in the table variable, i.e. @THeader.ApplyAmt
UPDATE mtblTransactionHeader SET mtblTransactionHeader.TransactionAllocationAmount = @THeader.TransactionAllocationAmount, mtblTransactionHeader.ApplyAmt = @THeader.ApplyAmt FROM @THeader, mtblTransactionHeader WHERE @THeader.TransactionHeaderID = mtblTransactionHeader.TransactionHeaderID - put the values back into original table
-- The 3rd query uses an incorrect column name in a sub-query and succeeds but rows are incorrectly qualified. This is very DANGEROUS!!! -- The issue exists is in 2008 R2, 2012 and 2014 and is "By Design"
set nocount on go if object_id('tempdb.dbo.#t1') IS NOT NULL drop table #t1 if object_id('tempdb.dbo
[code]....
This succeeds when the invalid column name is a valid column name in the outer query. So in this situation the sub-query would fail when run by itself but succeed with an incorrectly applied filter when run as a sub-query. The danger here is that if a SQL Server user runs DML in a production database with such a sub-query which then the results are likely not the expected results with potentially unintended actions applied against the data. how many SQL Server users have had incorrectly applied DML or incorrect query results and don't even know it....?
do i need to nest a query in RS if i want a calculated column to be compared against a multi value variable? It looks like coding WHERE calcd name in (@variable) violates SQL syntax. My select looked like
SELECT ... ,CASE enddate WHEN null then 1 else 0 END calcd name FROM... WHERE ... and calcd name in (@variable)
Can someone please answer a problem that I've run into. I know that it's probably something stupid. I keep getting this error:Server: Msg 107, Level 16, State 3, Line 1The column prefix 'vFirstTimeEntered' does not match with a table name or alias name used in the query.Here is my query:-----------------------------------------------------------------Update TimeSheetSectionSet TimesheetSection.SECSTARTDT = vFirstTimeEntered.schlstuidWhere timesheetsection.schlstuid = vFirstTimeEntered.schlstuid AND timesheetsection.sectionid = vFirstTimeEntered.sectionid AND Timesheetsection.secstartdt < '2005-08-01'------------------------------------------------------------------vFirstTimeEntered is a view that I created.Do I need a sub query? I know that if this was a select query I'd need to put vFirstTimeEntered in the FROM part but I don't know where it should go here.Thanks for any assistance.Scott
I have a set of data spread across a number of tables regarding stock market data. An example of this follows:
Market Capitalization...
Date CompA CompB 01/01/11 100 5 02/01/11 102 4
Share Price....
Date CompA CompB 01/01/11 100 100 02/01/11 101 99
Event Data...
Date Company 01/01/11 CompA 02/01/11 CompB
Pretty simply, I need a way to retrieve the market capitalisation and share price data based on the event data. So for instance I say 'oh, there is an event on the 01/01/11 involving company A, the market capitalisation on this day was 100, then for the next event it was 4 for company B.
I can also transpose the data so that the company name is in the rows and the dates in the columns for the market cap and share price tables, but this leads to the issue that when I try and get the data, I don't know how to query the correct company for that date.
For instance: SELECT Event.Date, Event.Company FROM Event
how do I now say.....
SELECT MarketCapitalisation.Column WHERE Column = Event.Company AND MarketCapitalisation.Date = Event.Date.
I have played around with a few basic joins, but I am having issue with the principle of that second to last line of SQL (so only getting the correct column).
I still have a copy of the data in excel so can flip things around as needed, but that would only mean that I would have the issue of WHERE Column = Event.Date instead of Event.Company.
I get the error "The column prefix 'contacts' does not match with a table name or alias used in the query".I am trying to obtain all fields from the communications table whether it is used or NULL.
When I run query in excel it gives result with different column sequence. The same query gives result with different column sequence when used in query analyzer or VBA Macro. E.g., Select * from ABC.
I have a column colC in a table myTable that has a value (e.g. '0X'). The position of a non-zero character in column colC refers to the ordinal position of another column in the table myTable (in the aforementioned example, colB).
To get a column name (i.e., colA or colB) from table myTable, I can join ("ON cte.pos = cn.ORDINAL_POSITION") to INFORMATION_SCHEMA.COLUMNS for that table catalog, schema and name. But I want to show the value of what is in that column (e.g., 'ABC'), not just the name. Hoping for:
COLUMN_NAME Value ----------- ----- colB 123 colA XYZ
I've tried dynamic SQL to no success, probably not executing the concept correctly...
I have data in a table (@Outer) that I am matching to a lookup table (@Inner) which contains multiple "matches" where nulls can match any value. By sorting the inner table and grabbing the top record, I find the "best" match. I know the sort and the null matches work but I don't understand why the correlated sub query below doesn't understand that the OJ prefix refers to the outer table.DECLARE @Outer TABLE ( OuterID int IDENTITY (1, 1) NOT NULL, MethodID int NULL, CompID int NULL, FormID int NULL, InnerID int NULL )
-- UPDATE Outer Table with best match from Inner table UPDATE @Outer SET InnerID = IJ.InnerID FROM @Outer OJ INNER JOIN ( SELECT TOP 1 I.* FROM @Inner I WHERE IsNull(I.MethodID, OJ.MethodID) = OJ.MethodID AND IsNull(I.CompID, OJ.CompID) = OJ.CompID AND IsNull(I.FormID, OJ.FormID) = OJ.FormID ORDER BY I.MethodID DESC, I.CompID DESC, I.FormID DESC ) IJ ON OJ.MethodID = IsNull(IJ.MethodID, OJ.MethodID) AND OJ.CompID = IsNull(IJ.CompID, OJ.CompID) AND OJ.FormID = IsNull(IJ.FormID, OJ.FormID) SELECT * FROM @Outer The result should be OuterID 1 matched to Inner ID 3 and OuterID 2 matched to Inner ID 5. Can anyone help me? Thanks in advance.
I want to update Flag column in second table based on the Adder names.
If the Applicatiion has atleast one AIX and Adder name is UDB then the flag would be True. If the Application has more the one AIX and Adder names are diferent then the flag would be null.
APpName OS Adder
App1 ||| Windows|||Null App1 ||| Linux |||UDB App1 ||| AIX |||UDB App1 ||| Linux |||Sql
I thought I saw this done once before. So today I hunted around inBooks OnLine and did a Google search. So far I have found nothingclose. So if you know how to do it, please tell me or if cannot bedone, I'd appreciate know that too.Thanks in advance,IanO
