Getting Back Multiple Columns
Oct 5, 2006
Hi, I have an asp.net app that essentially access, updates data in an sql server 2000.
Instead of writing a stored procedure for each call to a table is there a way to write one stored procedure that grabs all the data from a table, then my vb code could parse through and find the data....
Is this a stupid way, or should I stick to my original way... the problem is that I have hundreds of stored procedures....HUNDREDS... I don't think it's the way I am supposed to do this.

I have a person table
CREATE TABLE Person
(
PersonID INT
Name varchar(50),
HireDate datetime,
HireOrder int,
AltOrder int
)
Assume I have data like this
INSERT INTO Person VALUES(1, 'Rob', '06/02/1988', 0, 0)
INSERT INTO Person VALUES(2, 'Tom', '05/07/2016', 0, 0)
INSERT INTO Person VALUES(3, 'Phil', '01/04/2011', 1, 0)
INSERT INTO Person VALUES(4, 'Cris', '01/04/2011', 2, 0)
INSERT INTO Person VALUES(5, 'Jen', '01/04/2011', 3, 0)
INSERT INTO Person VALUES(6, 'Bill', '01/05/2011', 0, 0)
INSERT INTO Person VALUES(7, 'Ray', '01/23/2012', 0, 0)
I'm trying to simplify my requirement... providing the input of HireDate, HireOrder, and AltOrder, I need to be able to pick up the next person
For ex:, if I provide input, HireDate: 06/02/1988, HireOrder:0, AltOrder:0, the return value expected is "Tom" because he is the next person after the provided input.
For ex:, if I provide input, HireDate: 05/07/2016, HireOrder:0, AltOrder:0, the return value expected is "Phil" because he is the next person after the provided input. Though Phil and Cris have same dates, their HireOrder takes precedence in this case. If they also have same HireOrder, AltOrder would be coming in picture to determine next person
Another ex: if I provide input, HireDate: 01/04/2011, HireOrder:1, AltOrder:0, the return value expected is "Cris" because she is the next person after the provided input. Here hireorder determines.
If I provide, HireDate: 01/23/2012, HireOrder:0, AltOrder:0, as there is no person after this, I should be able to pick the first person on the list - in this case Rob.
I can write some business logic in front-end, but I thought it would be good, if I can move this to a stored procedure which can return me the PersonID for optimal performance.
I have tried writing various conditions but couldn't achieve a query that meets all my requirements here.
I'm even fine if my last condition is not met (returning the first person in the list, in case no one is available after the provided input).

I have a business need to create a report by query data from a MS SQL 2008 database and display the result to the users on a web page. The report initially has 6 columns of data and 2 out of 6 have JSON data so the users request to have those 2 JSON columns parse into 15 additional columns (first JSON column has 8 key/value pairs and the second JSON column has 7 key/value pairs). Here what I have done so far:
I found a table value function (fnSplitJson2) from this link [URL]. Using this function I can parse a column of JSON data into a table. So when I use the function above against the first column (with JSON data) in my query (with CROSS APPLY) I got the right data back the but I got 8 additional rows of each of the row in my table. The reason for this side effect is because the function returned a table of 8 row (8 key/value pairs) for each json string data that it parsed.
1. First question: How do I modify my current query (see below) so that for each row in my table i got back one row with 19 columns.
SELECT A.ITEM1,A.ITEM2,A.ITEM3,A.ITEM4, B.*
FROM PRODUCT A
CROSS APPLY fnSplitJson2(A.ITEM5,NULL) B
If updated my query (see below) and call the function twice within the CROSS APPLY clause I got this error: "The multi-part identifier "A.ITEM6" could be be bound.
2. My second question: How to i get around this error?
SELECT A.ITEM1,A.ITEM2,A.ITEM3,A.ITEM4, B.*, C.*
FROM PRODUCT A
CROSS APPLY fnSplitJson2(A.ITEM5,NULL) B, fnSplitJson2(A.ITEM6,NULL) C
I am using Microsoft SQL Server 2008 R2 version. Windows 7 desktop.

I'd like to first figure out the count of how many rows are not the Current Edition have the following:
Second I'd like to be able to select the primary key of all the rows involved
Third I'd like to select all the primary keys of just the rows not in the current edition
Not really sure how to describe this without making a dataset
CREATE TABLE [Project].[TestTable1](
[TestTable1_pk] [int] IDENTITY(1,1) NOT NULL,
[Source_ID] [int] NOT NULL,
[Edition_fk] [int] NOT NULL,
[Key1_fk] [int] NOT NULL,
[Key2_fk] [int] NOT NULL,
[Code] .....
Group by fails me because I only want the groups where the Edition_fk don't match...

I concatenate multiple rows from one table in multiple columns like this:
--Create Table
CREATE TABLE [Person].[Person_1](
[BusinessEntityID] [int] NOT NULL,
[PersonType] [nchar](2) NOT NULL,
[FirstName] [varchar](100) NOT NULL,
CONSTRAINT [PK_Person_BusinessEntityID_1] PRIMARY KEY CLUSTERED
[Code] ....
This works very well, but I want to concatenate more rows with different [PersonType]-Values in different columns and I don't like the overhead, of using the same table in every subquery ([Person_1]). Is there a more elegant way to do this, without using a temp table or something else?

Hello All,
I am rather new to reporting on SQL Server 2005 so please be patient with me.
I need to create a report that will generate system information for a server, the issue im having is that the table I am having to gather the information from seems to only allow me to pull off data from only one row.
For example,. Each row contains a different system part (I.e. RAM) this would be represented by an identifier (1), but I to list each system part as a column in a report
The table (System Info) looks like:-
ID | System part |
1 | RAM
2 | Disk Drive
10| CPU
11| CD ROM |
Which
So basically I need it to look like this.
Name | IP | RAM | Disk Drive|
----------------------------------------------
A | 127.0.0.1 | 512MB | Floppy
So Far my SQL code looks like this for 1 item
SELECT SYSTEM PART
FROM System Info
WHERE System.ID = 1
How would I go about displaying the other system parts as columns with info
Any help is much appreciated!

Hi,
I have multiple columns in a Single Table and i want to search values in different columns. My table structure is
col1 (identity PK)
col2 (varchar(max))
col3 (varchar(max))
I have created a single FULLTEXT on col2 & col3.
suppose i want to search col2='engine' and col3='toyota' i write query as
SELECT
TBL.col2,TBL.col3
FROM
TBL
INNER JOIN
CONTAINSTABLE(TBL,col2,'engine') TBL1
ON
TBL.col1=TBL1.[key]
INNER JOIN
CONTAINSTABLE(TBL,col3,'toyota') TBL2
ON
TBL.col1=TBL2.[key]
Every thing works well if database is small. But now i have 20 million records in my database. Taking an exmaple there are 5million record with col2='engine' and only 1 record with col3='toyota', it take substantial time to find 1 record.
I was thinking this i can address this issue if i merge both columns in a Single column, but i cannot figure out what format i save it in single column that i can use query to extract correct information.
for e.g.;
i was thinking to concatinate both fields like
col4= ABengineBA + ABBToyotaBBA
and in search i use
SELECT
TBL.col4
FROM
TBL
INNER JOIN
CONTAINSTABLE(TBL,col4,' "ABengineBA" AND "ABBToyotaBBA"') TBL1
ON
TBL.col1=TBL1.[key]
Result = 1 row
But it don't work in following scenario
col4= ABengineBA + ABBCorola ToyotaBBA
SELECT
TBL.col4
FROM
TBL
INNER JOIN
CONTAINSTABLE(TBL,col4,' "ABengineBA" AND "ABB*ToyotaBBA"') TBL1
ON
TBL.col1=TBL1.[key]
Result=0 Row
Any idea how i can write second query to get result?

MS SQL 2008 R2
I have the following effectively random numbers in a table:
n1,n2,n3,n4,SCORE
1,2,5,9,i
5,20,22,25,i
6,10,12,20,i
I'd like to generate the calculated column SCORE based on various scenarios in the other columns. eg.
if n1<10 and n2<10 then i=i + 1
if n4-n3=1 then i=i + 1
if more than 2 consecutive numbers then i=i + 1
So, I need to build the score. I've tried the procedure below and it works as a pass or fail but is too limiting. I'd like something that increments the variable @test1.
declare @test1 int
set @test1=0
select top 10 n1,n2,n3,n4,n5,n6,
case when (
n1=2 and
n2>5
)
then @test1+1
else @test1
end as t2

I have a quick question.
I need to execute some stored procedures in certain steps... all performing some inserts/updates
What i need is, a mechanism, by which i can roll back to the previous state if i encounter an exception (either in the app or SP)
so, if the my first two SP execute fine, perform their functionality like insert/update, and the third one fails...
how can i roll back to the initial state in ASP.NET.
would appreciate any info.
or redirection to the the location where i can look up some info on that.

I want to search in fulltextindexes for multiple searchterms in multiple columns. The difficulty is:
I don't want only the records with columns that contains both searchterms.
I also want the records of which one column contains one of the searchterm ans another column contains one of the searchterms.
For example I search for NETWORK and PERFORMANCE in two columns.
Jobdescr_________________________|Jobtext
Bad NETWORK PERFORMANCE________|Slow NETWORK browsing in Windows XP
Bad application PERFORMANCE_______|Because of slow NETWORK browsing, the application runs slow.
I only get the first record because JobDescr contains both searchterms
I don't get the second record because none of the columns contains both searchterms
I managed to find a workaround:
SELECT T3.jobid, T3.jobdescr
FROM (SELECT jobid FROM dba.job WHERE contains(jobdescr, 'network*') or CONTAINS(jobtext, 'network*') ) T1
INNER JOIN (SELECT jobid FROM dba.job WHERE contains(jobdescr, 'performance*') or CONTAINS(jobtext, 'performance*')) T2 ON T2.Jobid = T1.Jobid
INNER JOIN (SELECT jobid, jobdescr FROM dba.job) T3 ON T3.Jobid = T1.Jobid OR T3.Jobid = T2.JobId
It works but i guess this will result in a heavy database load when the number of searchterms and columns will increase.
Does anyone know a better solution?
Thanks in advance Bart Rouw

I previously posted a problem with result set bindings but I have not been able to resolve my problem. I guess all this comes with being new to programming in this environment! Anyway, I am trying to figure out how to process from an ADO.NET connection multiple rows with multiple columns. I have to read and manipulate each row. I was originally looking at using a foreach loop but have not been able to get it to work. One reply to my previous thought I should be using a data task to accomplish this. Could someone tell me the best way to handle this situation? As a note, I am new to programming in SSIS and basically trying to learn it as I go so please bear with me! Thanks in advance!

Is there a way to delete from multiple tables/views a column with a specificname? For example, a database has 50 tables and 25 views all have a columnnamed ColumnA. Is it possible to write a simple script that will deleteevery column named ColumnA from the database?Seems to be it would be possible and I can somewhat vision it usingsysobjects but without wanting to spend too much time generating the script(when I could in shorter time manually delete) thought I'd pose the question.Thanks.

So I have been trying to get mySQL query to work for a large database that I have. I have (lets say) two tables Table_One and Table_Two. Table_One has three columns: Type, Animal and TestID and Table_Two has 2 columns Test_Name and Test_ID. Example with values is below:
**TABLE_ONE**
Type Animal TestID
-----------------------------------------
Mammal Goat 1
Fish Cod 1
Bird Chicken 1
Reptile Snake 1
Bird Crow 2
Mammal Cow 2
Bird Ostrich 3
**Table_Two**
Test_name TestID
-------------------------
Test_1 1
Test_1 1
Test_1 1
Test_1 1
Test_2 2
Test_2 2
Test_3 3
In Table_One all types come under one column and the values of all Types (Mammal, Fish, Bird, Reptile) come under another column (Animals). Table_One and Two can be linked by Test_ID
I am trying to create a table such as shown below:
Test_Name Bird Reptile Mammal Fish
-----------------------------------------------------------------
Test_1 Chicken Snake Goat Cod
Test_2 Crow Cow
Test_3 Ostrich
This should be my final table. The approach I am currently using is to make multiple instances of Table_One and using joins to form this final table. So the column Bird, Reptile, Mammal and Fish all come from a different copy of Table_one.
For e.g
Select
Test_Name AS 'Test_Name',
Table_Bird.Animal AS 'Birds',
Table_Mammal.Animal AS 'Mammal',
Table_Reptile.Animal AS 'Reptile,
Table_Fish.Animal AS 'Fish'
From Table_One
[Code] .....
The problem with this query is it only works when all entries for Birds, Mammals, Reptiles and Fish have some value. If one field is empty as for Test_Two or Test_Three, it doesn't return that record. I used Or instead of And in the WHERE clause but that didn't work as well.

I have 4 tables involved here. The priority table is TABLE1:
NAMEID TRANDATE TRANAMT RMPROPID TOTBAL
000001235 04/14/2014 335 A0A00 605
000001234 04/14/2014 243 A0A01 243
000001236 04/14/2014 425 A0A02 500
TRANAMT being the amount paid & TOTBAL being the balance due per the NAMEID & RMPROPID specified.The other table includes a breakdown of the total balance, in a manner of speaking, by charge code (thru a SUM(OPENAMT) query of DISTINCT CHGCODE
TABLE2
NAMEID TRANDATE TRANAMT RMPROPID CHGCODE OPENAMT
000001234 04/01/2014 400 A0A01 ARC 0
000001234 04/05/2014 -142 A0A01 ARC 228
000001234 04/10/2014 15 A0A01 ALT 15
[code]...
Also with a remaining balance (per CHGCODE) column. Any alternative solution that would effectively split the TABLE1.TRANAMT up into the respective TABLE2.CHGCODE balances? Either way, I can't figure out how to word the queries.

Hello,I'm trying to create a simple back up in the SQL Maintenance Plan that willmake a single back up copy of all database every night at 10 pm. I'd likethe previous nights file to be overwritten, so there will be only a singleback up file for each database (tape back up runs every night, so each daysback up will be saved on tape).Every night the maintenance plan makes a back up of all the databases to anew file with a datetime stamp, meaning the previous nights file stillexists. Even when I check "Remove files older than 22 hours" the previousnights file still exists. Is there any way to create a back up file withoutthe date time stamp so it overwrites the previous nights file?Thanks!Rick

New to Database Mirroring and I have a question about the Principal database server. I have a Database Mirroring setup configured for High-safety with automatic fail over mode using a witness.
When a fail over occurs because of a lost of communication between the principal and mirror, the mirror server takes on the roll of Principal. When communication is returned to the Principal server, at some point does the database that was the previous Principal database automatically go back to being the Principal server?

Can I write a having statement for multiple columns? Here's my situation: I want to select duplicates from a table based off of 3 fields:Normally one would use HAVING COUNT(*) > 1however, I need to INSERT INTO my table based on duplicates of the 3 fields but also insert the key from the first table, ie:insert into #TempTable (key, field1, field2, field3)select key, field1, field2, field3 from Table1 order by field1, field2, field3 Having COUNT(field1)>1 and COUNT(field2)>1 and COUNT(field3)>1 My question is this: Will this having statement compare all three fields of this row to all three fields of the other rows, or does it do each column independantly?for example:row 1: a b g row 2: a c k row 3: j c k These rows aren't the same, even though there are 2 a's, I want it to look at the entire row, and not return all three of these.

Hey all,
I was curious if this was possible...
I basically have 2 queries I'd like to combine into one. The only difference in the queries is one clause in the WHERE statement
so here is an idea of what I'm talking about
SELECT COUNT(*) as HighStock FROM products WHERE qty > 100
now lets say I needed to do one for low I would have to run that query 2 times with different alias's and change the qty...
is there a way to get all that in one result set? Something like
SELECT COUNT(*) as HighStock, COUNT(*) as LowStock FROM products WHERE qty > 100 AND LowStock = qty < 20
so then my result would be
HighStock LowStock
50 10
anyone have any clues on that? thanks! :)

hi guys,
I have a table which has 4 columns A,B,C,D. it is somewhat like this:
A B C
S U 8
S U 10
S U 3
s V 14
S V 36
T U 25
T U 34
T U 9
T V 5
T V 1
This is the way i have in my database. I need to check which is the max in column C for values in Column A and Column B. First i need to start from column A. If it is S, then i need to see column B, if it is U then max[Column C] for only U & S. then when it becomes V, I need to get max [Column C] for only V & S. So on and so forth. So finally my output should be:
S U 10
S V 36
T U 34
T V 5
How can i do this?
regards,
David

I have seen questions posted a number of times where someone wants to find the maximum or minimum value from a set of columns in a single row of a table.
This script demonstrates two methods for finding the maximum value in a row across a set of columns in the row when any or all of the columns are allowed to be null or equal.
Method 1 uses a UNION ALL sub query for all the columns with a MAX. It is much simpler to code and test, especially when you get much past 4 columns. Adding another column is as simple as adding one more SELECT to the subquery.
Method 2 uses a CASE statement to determine the MAX. It is much more complex to code (and test), and gets exponentially harder to code as the number of columns goes up. I think 5 or 6 columns may be about the limit of complexity of coding that you would want to take on. One advantage of this script is that you can use the simpler to code Method 1 to test the more complex code for the Method 2 if you choose to implement it as a CASE statement.
If you have another method you would like to contribute, feel free. Also, if anyone wants to post performance test results, that would be nice.
print 'Create table to hold test data'
create table #t (
number int not null primary key clustered,
Val1 int,
Val2 int,
Val3 int,
Val4 int
)
GO
print 'Load test data'
insert into #t

I've been working on this project for a few months now. This is my first SS2005 project. I'm using SSIS, SSAS, and SSRS. I deal with volume statistics on labratory tests. The three main identifying columns of a test are: Bill_Item_Id, Mnemonic, and [Test Name]. My main dimension table uses the primary key column: Bill_Item_ID. I recently learned that I can't use this column as a primary key because there are a couple tests that have the same Bill_Item_Id, but different Test Names. I know that I can't have multiple primary keys, but is there a way I could say that no two rows in this table will have the same Bill_Item_ID, Mnemonic, AND [Test Name]? Then my fact table would have all three columns and match on those three instead of just one. I realize this will take a lot of work to rework SSAS and SSIS to accomadate for this, but unfortunately no one brought this tidbit of information to my attention.
Thank you very much.

Is it possible to use multiple columns for a not in?
something like this;
Select * From MyTable
Where X , Y
Not In (Select X , Y FROM MyOtherTable )
If not, how would I accomplish this?
