How Do I Populate A Formview From Multiple Columns In A Gridview
Jun 29, 2006
Hi,
I have a master/detail scenario whereby to populate a formview, the user selects a row in the gridview. The SqlDataSource used to populate the formview needs to check 2 columns from the gridview, ZRef (which is the SelectedValue of the Gridview) and ZName (a string).
From searching the forums it looks like I have to programmatically assign the SelectParameters in order to get ZName from the gridview. Seems fair enough, so I set the parameters in the 'Selecting' event of the SqlDataSource. (Code shown below).
However the formview never shows. In debug I can see that the values I'm setting in the SelectParameters.Add are correct; and if I set the default values for those parameters in the SqlDataSource itself, everything works fine.
Can anyone point me to some sample VB code that does this - I'm sure this must be a common situation.
Thanks.
Protected Sub sdsOff_Selecting(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.SqlDataSourceSelectingEventArgs)
Dim tmpSDS As SqlDataSource
Dim tmpLBL As Label
tmpSDS = CType(FormView1.FindControl("sdsOff"), SqlDataSource)
If tmpSDS Is Nothing Then
Server.Transfer("ErrorOnPage.htm")
End If
tmpLBL = Me.GridView1.Rows(GridView1.SelectedIndex).FindControl("lblName")
If tmpLBL Is Nothing Then
Server.Transfer("ErrorOnPage.htm")
End If
tmpSDS.SelectParameters.Clear()
tmpSDS.SelectParameters.Add("ZRef", GridView1.SelectedValue) 'In debug, this shows 7 - which is correct
tmpSDS.SelectParameters.Add("ZName", tmpLBL.Text) 'In debug, this shows 'Fred Bloggs' - which is correct
End Sub

Hi,
My formview or gridview control stops updating or deleting a record once the record has a null value.
I have table tblTest with the following
pkID int NOT NULL **IDENTITY COLUMN** string1 varchar(30) string2 varchar(30)
I then create a SqlDataSource with the statement:
Select * From [tblTest]
I have the insert, update and delete statements generated, and choose optimistic concurrency. I add a couple records of dummy data.
I then drag a Formview control onto the page, and bind it to the SqlDataSource I just created. I then fire it up in my browser, and I can then update, insert and delete records. However, as soon as I update a record with a null value, I can no longer update or delete that record.
So, if I had a record in my FormView like:
string1: foo string2: bar
I can update and delete normally. And when I update to:
string1: foo string2:
the database correctly inserts a null value into string2. However, once that null is in the record, I can't change anything about the record. If I try to delete the record, the FormView will then display the previous record, but I can still page to the record that should have been deleted, and it still exists in the db. If I try to update the record, the edits I make will not keep and the process will fail silently.
What am I doing wrong? Should i be binding to a different object?
Regards,
Chris

Using 3.5
If I have a sqldatasource on the page, is it run if it is not bound to a data object like a gridview?
Seems like if i want to access the data (like set a label text) from the sqldatasource I have to use code to first create a dataview then pick throught it. This seems like I'm running it twice. I'm new at .net so I dont know how to tell.
I don't want to write data select code programatically when I can just through an SDS on the page, but wondered it it ran just because it's on the page.

Dear All,
i have a SqlDataSource with a simple select command(e.g. "select a,b,c from foo"). The insert command is a stored procedure and takes less parameters than there are columns in select statement (e.g. "insertFoo(a char(10))").
When used in combination with form view, i get "Procedure or function insertFoo has too many arguments specified" error.
It seems that form view always posts all columns as parameter collection (breakpoint in formview_inserting event shows this) to insert command.
Am I doing something wrong or is this by design? Is the only solution to manualy tweak parameters in formview_inserting event?
TIA

Guys, here is my scenario:
I have 3 tables
1) Vendor
2) Service
3) Service Product
Each vendor has the ability to have any number of services, all with any number of service products.
How should I setup my page so I can edit/insert vendors, and tie a list of service products and services to them?
My plan was to have a Formview with either a checkboxlist, or multilist (to select multiple items - but they don't work that way) and then store selected items in another table (each item selected with its own record) to hold onto the vendor id and tie it to a service id and a product id, but I was unsure how to do this.
Any help would be greatly appreciated.
FYI I am writing in VB.

Basically like the topic says, I need to populate a filename with data from other columns and im having a tough time doing it.
Code:
UPDATE nice_cls_calls_0027
SET vcarchivepath = 'G:Nice Storageicestorage.safeautonet.netSafe Auto Task - Logger (807101)2006_feb_1SC_807101_'start_time'_'=stop_time'_'=channel'_'=cls_call_id'.aud'
I need start_time, stop_time, channel, and cls_call_id to populate the filename. The first 2 are datetime fields in the db and no conversion is needed for them, just raw data. The remaining two are smallint and raw data is needed there also. Any help would be greatly appreciated. TY

I'm looking for an efficient way to populate derived columns when Iinsert data into a table in SQL Server. In Informix and PostgreSQLthis is easily done using the "for each row..." syntax, but all I'vebeen able to come up with for SQL Server is the following:create table testtrigger(id integer unique, b integer, c integer)gocreate trigger testtrigger_ins on testtriggerfor insert asupdate testtrigger set c = (select ...some_function_of_b... fromtesttrigger t1,inserted t2where t1.id = t2.id)where id in (select id from inserted);gowhere id is testrigger's unique id field, and c is a field derived fromb.This seems terribly inefficient since each insert results in an extraselect and update. And if the table is large and unindexed (which itcould be if we are bulk loading) then I would imagine this would bevery slow.Are there any better ways of doing this?Many thanks,...Mike Dunham-Wilkie

I have built an Advanced Search page which allows users to select which columns to return (via checkbox) and to enter search criteria for any of the selected columns (into textboxes). I build the SQL statement from the properties of the controls. Works great.
My problem is getting my gridview control to play nicely. At first I used a SqlDataReader and bound the gridview to it, thus giving me the ability to run new SQL statements through it (with different columns each time). Worked nicely. But, per Microsoft, sorting can only be done if the gridview is bound to a datasource control like the SqlDataSource. So I wrote the code to handle sorting. No big deal; worked nicely. But I could not adjust the column widths programmatically unless bound to a datasource control like the SqlDataSource. And could not figure out a work around.
So, I decided to use the SqlDataSource. Works great. Except, I cannot figure out how to run a new SELECT statement through the SQLDataSource and have the gridview respond accordingly. If I try to return anything other than the exact same columns defined declaratively in the html, it pukes. But I need to be able to return a new selection of columns each time. For example, first time through the user selects columns 1,2,3,4 – the gridview should show those 4 columns. The second time the user selects columns 2,5,7 – the gridview should those 3 columns (and ONLY those 3 columns). Plus support selection and sorting.
I am desperate on this. I've burned 2.5 days researching and testing. Does anyone have any suggestions?
Thanks,
Brad

one of my webpages uses the following sql query to allow the user to search through the database and present the qualifying data in gridview:
SELECT * FROM [Table1] WHERE ([comments] LIKE '%' + ? + '%')
how could i expand this so that the user can also search through the database but instead by searching through another column such as [type]?

Hi,
Is it possible to populate a dataset with tables returned by a stored proc?Consider this:
BEGINSELECT * FROM Table1SELECT * FROM Table2SELECT * FROM Table3END
If that is my stored proc, could I call it from a page and automatically populate a dataset with all 3 tables (if yes, then how?), or would I have to make 3 seperate calls to the db for each table?
Thanks

What I need to do is re-populate a unique number into multiple fields,
Let me explain, An employee can appear in the first table only once but can be in the second table multiple times with multiple employee numbers .There is a field called TFN that is unique and we are using it to create a unique id called KRid so what I have done is created 2 tables namely TEST_TBL and TEST2_TBL . In TEST_TBL I am populating a KRid with a unique no being produced by the TFN field only once i.e 12345 being the resulting unique id number. If an employee has 2 employee numbers i.e empno 1 and empno 1000,only employee no 1 will have the unique KRid created but nothing for 1000 because the record already exists , so what has me stumped is that the TFN for employee empno 1 and the TFN for empno 1000 are the same. How do I get the KRid (12345 from empno 1) to populate empno 1000 in TEST2_TBL , The second table has all records in so I can group the second table by TFN id but how do I populate employee 1000 in the second table with the KRid 12345.
Please help!!!!! Below are how the tables are set up and an example of the result.
TABLE 1
if exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[TEST_TBL]') and OBJECTPROPERTY(id, N'IsUserTable') = 1)
drop table [dbo].[TEST_TBL]

) ON [PRIMARY]
GO
TABLE 2
if exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[TEST2_TBL]') and OBJECTPROPERTY(id, N'IsUserTable') = 1)
drop table [dbo].[TEST2_TBL]
GO
CREATE TABLE [dbo].[TEST2_TBL] (
[EmpNumber] [char] (32) COLLATE Latin1_General_CI_AS NULL ,
[TFN] [char] (32) COLLATE Latin1_General_CI_AS NULL ,

[EmpStatus] [int] NULL ,
[EmpType] [int] NULL ,
[CommonName] [char] (32) COLLATE Latin1_General_CI_AS NULL
) ON [PRIMARY]
GO
Query goes as follows for table 1:
SELECT NPE000.EmpNumber, NPET00.RecordStatus, NPE000.KR_ID, NPE000.Surname, NPE000.FirstName, NPE000.SecondName, NPE000.Class, NPE000.DateEmployed, NPE000.DateOfBirth, NPE000.HoursPerDay, NPE000.HoursPerWeek, NPE000.PassportNo, NPE000.AwardCode, NPE000.EmailPayslipTo, NPE000.Location, NPE000.Grade, NPE000.DateTerminated, NPE000.EmploymentType, NPE000.DistCode, NPE000.EmpStatus, NPET00.TaxRefNo FROM NPE000 NPE000, NPET00 NPET00 WHERE NPET00.RecordStatus = 0 and NPET00.TaxRefNo <> ' 111111111' and NPET00.TaxRefNo <> ' 000000000' AND LENGTH(NPET00.TaxRefNo) >= 9 AND LENGTH(NPE000.KR_ID) >= 0 AND NPE000.EmpNumber = NPET00.EmpNumber
Query goes as follows for table 2:
SELECT NPE000.EmpNumber, NPE000.FirstName, NPE000.Surname, NPE000.Class, NPE000.Location, NPE000.EmploymentType, NPE000.EmpStatus, NPET00.TaxRefNo, NPE000.Paypoint, NPE000.KR_ID, FROM NPE000, NPET00 WHERE Recordstatus = 0 and (EmploymentType = 1 AND EmpStatus = 1 AND NPE000.EmpNumber = NPET00.EmpNumber
From this you can see that in table 1 it will only create 1 KR_ID for only one employee number but in table 2 I am bringing through all employee records. In table 2 I can group by NPET00.TaxRefNo which will bring all NPET00.TaxRefNo's togeather. From that I would like to populate the other employee numbers with the unique KR_ID.
Example:Table 1
000001,Jackson,James,Sam,7.6,38,12345,475431212
Example:Table 2
000001,Jackson,James,Sam,7.6,38,12345,475431212
001000,Jackson,James,Sam,7.6,38,,475431212
I hope this helps
Thanks in advance

I need to, ultimately, create a flatfile for exporting insurance information to a third-party vendor. Each individual is to have no more than 1 line per file, which contains their coverage information, if any, on 4 different type of insurance. What i need is for 2 fields in a table to determine the output for multiple fields in the flatfile.
What I have so far works, to an extent. If I have insurance types 1, 2, 4 (of types 1-4) required output is (__ = 2 blank spaces):
1A 1B 1C 1D 1E 2A 2B 2C 2D 2E 3A 3B 3C 3D 3E 4A 4B 4C 4D 4E
== == == == == == == == == == == == == == == == == == == ==
Y N __ MD XX Y N __ MD XX N __ __ __ __ Y N __ DN XX
If they have coverage, A always = Y, B always = N, C always = blank(null), D is their ins. type, E is their cov. type(CASE statement). if they DON'T have that type of coverage, A always = N and the remaining field are NULL.
After a lot of work, and scouring a forum or 2, I attempted a whole lot of CASE functions. Below is an sample of code representing the 1x statements. This same code is repeated 4 times with the 1x being altered with 2x, 3x, 4x.
CASE HB.PLAN_TYPE
WHEN '10' THEN 'Y'
ELSE 'N' END AS 1A,
CASE HB.PLAN_TYPE
WHEN '10' THEN 'N'
ELSE ' ' END AS 1B,
' ' AS 1C,
CASE HB.PLAN_TYPE
WHEN '10' THEN HB.BENEFIT_PLAN
ELSE ' ' END AS 1D,
CASE HB.PLAN_TYPE
WHEN '10' THEN (CASE WHEN HB.COVRG_CD ='1' THEN 'XX'
WHEN HB.COVRG_CD ='2' THEN 'YY'
WHEN HB.COVRG_CD ='3' THEN 'ZZ'
ELSE 'WW' END)
ELSE ' ' END AS 1E,
It works to an extent. While the desires/required output it above, the output this produces (same scenario) is:
1A 1B 1C 1D 1E 2A 2B 2C 2D 2E 3A 3B 3C 3D 3E 4A 4B 4C 4D 4E
== == == == == == == == == == == == == == == == == == == ==
Y N __ MD XX N __ __ __ __ N __ __ __ __ N __ __ __ __
1A 1B 1C 1D 1E 2A 2B 2C 2D 2E 3A 3B 3C 3D 3E 4A 4B 4C 4D 4E
== == == == == == == == == == == == == == == == == == == ==
N __ __ __ __ Y N __ MD XX N __ __ __ __ N __ __ __ __
1A 1B 1C 1D 1E 2A 2B 2C 2D 2E 3A 3B 3C 3D 3E 4A 4B 4C 4D 4E
== == == == == == == == == == == == == == == == == == == ==
N __ __ __ __ N __ __ __ __ N __ __ __ __ Y N __ DN XX
While there is supposed to be 1 line, regardless of number of insurance types, it only produces 1 line per type. I first tried this in Access, and was able to get it to work, but it required multiple queries resulting in a crosstab, export to Excel and manually manipulate the data, export to text file to manipulate, import back into Excel to manipulate, import back into Access and finally export into a flatfile. Far too much work to produce a file which is why I'm trying to convert it to raw SQL.
Any assistance in this matter would be greatly appreciated.

I have 5 or more tables to join to get a particular output which has to be sent to a destination table. In the 5 tables some are inner joins and some are left outer join. I am opting for stored procedure at this point. But I would like to know how can this be done in data flow transformations having multiple souce and merge joins or any other alternates. I tried using merge join, but this does not accept more than two tables.
I saw this simple post which kick started me to use ssis transformations to stored procedures. But I encounter issue.

error
"The destination component does not have any available inputs for use in creating a path".

Hi, I am seeking a hopefully easy solution to spit back an error message when a user receives no results from a SQL server db with no results. My code looks like this What is in bold is the relevant subroutine for this problem I'm having. Partial Class collegedb_Default Inherits System.Web.UI.Page Protected Sub submit_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles submit.Click SqlDataSource1.SelectCommand = "SELECT * FROM [college_db] WHERE [name] like '%" & textbox1.Text & "%'" SqlDataSource1.DataBind() If (SqlDataSource1 = System.DBNull) Then no_match.Text = "Your search returned no results, try looking manually." End If End Sub Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load SqlDataSource1.SelectCommand = "SELECT * FROM [college_db] ORDER BY [name]" SqlDataSource1.DataBind() End Sub Protected Sub reset_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles reset.Click SqlDataSource1.SelectCommand = "SELECT * FROM [college_db] ORDER BY [name]" SqlDataSource1.DataBind() End SubEnd Class I'm probably doing this completely wrong, I'm a .net newb. Any help would be appreciated. Basically I have GridView spitting out info from a db upon Page Load, but i also have a search bar above that. The search function works, but when it returns nothing, I want an error message to be displayed. I have a label setup called "no_match" but I'm getting compiler errors. Also, next to the submit button, I also have another button (Protected sub reset) that I was hoping to be able to return all results back on the page, similar to if a user is just loading the page fresh. I'd think that my logic would be OK, by just repeating the source code from page_load, but that doens't work.The button just does nothing. One final question, unrelated. After I set this default.aspx page up, sorting by number on the bottom of gridview, ie. 1,2,3,4, etc, worked fine. But now that paging feature, as long with the sorting headers, don't work! I do notice on the status bar in the browser, that I receive an error that says, "error on page...and it referers to javascript:_doPostBack('GridView1, etc etc)...I have no clue why this happened. Any help would be appreciated, thanks!

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 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

allNumbers

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.
