Add Unique Constraint On 3 Fields?
Jul 21, 2015I want to add a unique constraint on 3 fields, to only allow the value in the field ONE time. The value will NEVER be the same for anything else. This is the table structure
Code:
Create Table Employees
(
P_Id int NOT NULL,
InstructorName varchar(255) NOT NULL,
CourseName varchar(100) NOT NULL,
DataTableName varchar(100) NOT NULL
)
I want to create a unique constraint across the fields Instructorname, CourseName, DataTableName as their is ONLY 1 instructor per course per table so those 3 fields will ALWAYS hold unique values. I think the constraint syntax would go like so, but want to check before I go butchering some sql syntax.
constraint syntax:
Code:
Alter Table Employees
Contstraint uniqueEmployee Unique (InstructorName ,CourseName ,DataTableName )
Unique Fields In SQL Server Tables
Oct 12, 2006I feel sure that this is a very naive question, but it is freeky me out that I can solve it. With SQL server what is the easiest way to make a field other than the Primary key unique?Would appreciate help with this. ThanksPaul

Oct 25, 2013I'm designing an app for stock keeping. In my DB, I have a field called "ItemSerialNo" and I made it unique(but not the table's primary key). On my front end, I have a text box for Item Serial No and a combo box loaded with the item brands and also a save button. I know that if I try to save a serial no already existing in my DB, the app won't allow me because of the unique property of the field named "ItemSerialNo". But I want to be able to save a serial no already existing in my DB but with a different brand name.
For example, I want to be able to save information like:
1. ITEM SERIAL NO = 12345
BRAND NAME = AA
2. ITEM SERIAL NO = 12345
BRAND NAME = BB.
Re-populate A Unique Number Into Multiple Fields
Oct 14, 2004What 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.

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

Retrieving Unique Fields From Table Into Existing Dataset
Jun 18, 2008I am working on creating a report which is retrieving data from a SQL 2005 database and being displayed in a C#.net web page. Presently, I am binding the dataset to a ASP:Gridview on the web page.
I am currently retrieving most of the needed fields using the following SQL statement:PROCEDURE [dbo].[pr_getReportTickets] @DateCreated nvarchar(15) ASBEGIN
-- SET NOCOUNT ON added to prevent extra result sets from -- interfering with SELECT statements. SET NOCOUNT ON;
-- Insert statements for procedure hereSELECT tbl_Queue.num_TicketNumber AS TicketID , tbl_Users.str_Name AS Technician , tbl_Queue.str_QueueLocator AS TechNTID , tbl_Queue.dat_ReceivedRequest AS dateCreated , tbl_Queue.dat_DueDate AS DueDate , tbl_Queue.str_TaskName AS TicketTitle , tbl_Queue.str_Requestor AS RequestorNTID --, I need most current dat_TimeStamp from tbl_Notes here for this record --, I need most current int_PercentComplete from tbl_Notes here for this record --, I need to sum up all of int_MinutesWorked fields from tbl_Notes here for this record , MasterEmp.dbo.fn_FormatFullName(tbl_employee.str_fname, tbl_employee.str_lname) AS RequestorName , tbl_Queue.str_TicketType AS TicketType , tbl_Status.str_TaskStatus AS TicketStatus , tbl_Severity.str_Priority , tbl_Complexity.str_Complexity , tbl_Severity.str_Priority + N' / ' + tbl_Complexity.str_Complexity AS Priority , tbl_Queue.dat_CompleteDate as DateCompleted
FROM dbo.tbl_Queue LEFT OUTER JOIN MasterEmp.dbo.tbl_employee AS tbl_employee ON dbo.tbl_Queue.str_Requestor = tbl_employee.str_ntid LEFT OUTER JOIN tbl_Users ON tbl_Queue.str_QueueLocator = tbl_Users.str_ntid LEFT OUTER JOIN tbl_Status ON tbl_Queue.num_Status_CD = tbl_Status.num_Status_CD LEFT OUTER JOIN tbl_Severity ON tbl_Queue.str_Severity = tbl_Severity.str_Severity LEFT OUTER JOIN tbl_Complexity ON tbl_Queue.int_ComplexID = tbl_Complexity.int_ComplexID
WHERE (dbo.tbl_Queue.dat_ReceivedRequest > CONVERT(DATETIME, @DateCreated, 102))
ORDER BY TicketType, tbl_Queue.str_Severity
I also have another table called tbl_Notes. This table contains an unlimited quantity of records for every “num_TicketNumber�. This table contains the following fields: num_TicketNumber, str_TechRep, str_Notes, dat_TimeStamp, int_PercentComplete and int_MinutesWorked
I need to add two more fields to the query, but I do not know how to tell the SQL statement how to retrieve the data for the specfic record and inbed the fields into the Dataset being returned from the database to the web page.1) The first field I need is the most current recorded Date field from the tbl_Notes table for the each of the records returned in the above SQL statement. Similar to: SELECT TOP (1) dat_TimeStamp FROM tbl_Notes WHERE(num_TicketNumber = xxxx) ORDER BY dat_TimeStamp DESC2) The other field I need to return with the Dataset is the sum of the int_MinutesWorked for each of the tickets being retrieved. Similar to: SELECT SUM(int_MinutesWorked) AS TotalMinutesFROM tbl_Notes WHERE (num_TicketNumber = 49)

What Is The Difference Between A UNIQUE INDEX And A UNIQUE CONSTRAINT?
Sep 22, 2004A UNIQUE INDEX must inherently impose a unique constraint and a UNIQUE CONSTRAINT is most likely implemented via a UNIQUE INDEX. So what is the difference? When you create in Enterprise Manager you must select one or the other.

Mar 7, 2001Hi everyone,
I need urgent help to resolve this issue...
As far as the performance goes which one is better..
Unique Index(col1, col2) OR Unique constraint(col1, col2) ?
Unique constraint automatically adds a unique index
and unique index takes care of uniqueness then whats the use of unique constraint ?
Which one do one use ?

How To Select Unique Row When Entire Row Not Unique?
Mar 12, 2008I am having a problem trying to figure out the best way to get the results I need. I have a table of part numbers that is joined with a table of notes. The table of notes is specific to the part number and user. A row in the notes table is only created if the user has entered notes on that part number. I need to create a search that grabs all matches on a keyword and returns the records. The problem is that it currently returns a row from the parts table with no notes and a separate row with the notes included if they had created an entry. It seems like this should be easy but it eludes me today.
Here is the code
Code Snippet
create procedure SearchPartKeyword
(
@Keyword varchar(250) = null,
@Universal_Id varchar(10) = null
)
as
select p.PartNumber, p.Description, p.ServiceOrderable, n.MyNotes, p.LargestAssembly, p.DMM,
p.Legacy, p.Folder, p.Printer
from Parts p inner join notes n on p.PartNumber = n.Identifier
where n.Universal_ID = @Universal_ID and p.Description like @Keyword
union
select p.PartNumber, p.Description, p.ServiceOrderable, '' as MyNotes, p.LargestAssembly,
p.DMM, p.Legacy, p.Folder, p.Printer
from Parts p
where p.Description like @Keyword
and the results:
PartNo Description SO Notes LA DMM Legacy Folder Printer
de90008 MAIN BOARD 1 DGF1 114688 0 0 0
de90008 MAIN BOARD 1 I love this part Really I do DGF1 114688 0 0 0
This could return multiple part numbers and If they have entered notes I want the row with the notes
Thank You

Jan 28, 2008
I have just started using SQL Server reporting services and am stuck with creating subreports.
I have a added a sub report to the main report. When I right click on the sub report, go to properties -> Parameters, and click on the dropdown for Parameter Value, I see all Sum and Count fields but not the data fields.
For example, In the dropdownlist for the Parameter value, I see Sum(Fields!TASK_ID.Value, "AppTest"), Count(Fields!TASK_NAME.Value, "CammpTest") but not Fields!TASK_NAME.Value, Fields!TASK_ID.Value which are the fields retrieved from the dataset assigned to the subreport.
When I manually change the parameter value to Fields!TASK_ID.Value, and try to preview the report, I get Error: Subreport could not be shown. I have no idea what the underlying issue is but am guessing that it's because the field - Fields!TASK_ID.Value is not in the dropdown but am trying to link the main report and sub report with this field.
Am I missing something here? Any help is appreciated.

The purpose of this is to reduce data entry by field personnel.I think I have the create trigger statement correct, but I'm a little confused on the update statement.
In a nutshell, how can I write something like:
UPDATE "TABLENAME"
SET DATAFIELD1 = DATAFIELD2
WHERE RECORDNUMBER = (THE SAME RECORD NUMBER)
I do know that I have to ensure that sp_dboption Recursive Triggers value is set to false, thanks.
Using LIKE To Find Any Of Fields In One Table In Fields Of Another
Jul 31, 2013 I have a list of items in one table and a field (pageName) in another table that may contain one of the aforementioned items somewhere within that field. There is no fixed position within the field where the itemNo may be so I can't just use SUBSTRING(pageName,2,5) in(select itemNo from tblItem).
Logically, it's like I need to combine IN and LIKE: select pageName where pageName LIKE IN %select itemNo from tblitemNo%..LIKE can only handle one comparison string.
Drillthrough In Calculated Fields Enable When Drillthrough Option Is Disable In Original Fields, Is This A BUG?
Jan 21, 2008Hi people
My users are having troubles with link to default drillthrough report when reports are exported to excel (they REALLY don't like this behavior ), so I decided set all of them disabled in report model, this work fine, but calculated field in reports has this drillthrough link.
Let me show you the situation. Entity Product has an UnitaryCost field, I set the EnableDrillthrough Property in False so when I export a report with this field, no link is shown.
But if I create in the report a calculated field Round(UnitaryCost) this field has a Drillthrough Link
Is this the standard and expected behavior? or its simply a BUG?
Have I done something wrong in my model? and in this case, How I can correct this?
regards.

PK Not Unique ?
Jan 19, 2001I have one table called agents.
In this table there are two columns, one called "company number" (NUMBER) and one called "company name" (VARCHAR). I have an index called agents_PK that are unique and indexes both columns with company number as first and company name as second in the column order.
But when I look at the data in the column company number its not unique, I find several rows with the same number.
How come ?
