I have two tables. A table called users (content speaks by it self) and a table called groups.
Since i want every user to be able to be a member of several groups and, of course, a group to have several users i have made a junction table called jt.
The junction table contains userId's and groupId's according to the user-group bindings. The primary key(identity) in the junction table is a int named jtId.
Now i want to take out all posts from the junctiontable and the corrresponding userName (s) from the users-table and the corresponding groupName from the groups-table.
Can somebody please help me to make a SQL command that will di that for me. I have tried with INNER JOIN and several SELECTS in the same command.
Looking for some help here, so thanks for any input. I'm a painfully new newbie to SQL scripting.Situation: I have a simple database to handle an organization's events. Those events are categorized and may have more than one category assigned to each event. I need a maintenance Web Form to update their events.Set Up (so far): I have a CATEGORIES table. It has an auto incrementing UID and a Category name field. This table will be updated so infrequently, I plan to update it manually (no need for a maintenance Web Form). Next is the EVENTS table. It also has an auto incrementing UID along with several fields (Title, Location, DateTime, etc.). The junction table is named jEVENTSCATEGORIES. It has its own auto incrementing UID along with 2 fields named for the primary keys (UIDs) in the other 2 tables (EventsID and CategoryID).Goal: On the Web Form, I have a CheckBoxList control that's populated by the CATEGORIES table. One or more categories can be checked for each event. I have a FormView control that allows Edits and Inserts.Need: I need to know the INSERT statement(s) required to insert a new record in the EVENTS table and then to update one or more rows in the junction table (jEVENTSCATEGORIES).My Assumptions: I know how to create SELECTs and INSERTs and whatnot, but I'm not certain how to create a second INSERT statement that is based on a variable (or output) from a previous action. So any help would be MUCH appreciated. Thanks for your time!
Hi i have a junction table(UserGroups) which is linking my users table with my groups table, however when the information is coming back in the format below, instead i want the group names to appear in only one field, instead of repeating the same data, could someone please tell me what i need to change
UserName: Edwin CarolsUserAge: 28JobTitle: ManagerGroupName: AFC Below is my SQL statement; SELECT Users.UserName,Users.UserAge, Users.JobTitle, Groups.GroupName FROM Users INNER JOIN UserGroups ON Users.UserID = UserGroups.UserID INNER JOIN Groups ON UserGroups.GroupID = Groups.GroupID WHERE (Users.UserID = '5')
As an example, I am building an authentication mechanisim that will usedata in the 3 left tables to determine rights to objects in adestination table, diagrammed below. In this structure, multiplerecords in the left tables will point to multiple records in the righttable. Normally, I would approach this problem using junction tables(LeftID, RightID) to create many-to-many joins.However, given the structure of each table is nearly identical (as faras the linking IDs are concerned), I could also use a single junctiontable with columns for each available table ID (LeftID1, LeftID2,LeftID3, RightID). In this table, only two IDs would be utilized perrow (LeftIDx -> RightID).In both designs, the needed rights information is returned from fairlysimple views, thus the end result is equivalent. The advantage to thesecond, multi-ID junction table design, is a simpler databasestructure. However, never using this approach before, I am unsure ofthe potential future performance impacts.Any significant downsides to this second design? Examples of anabbreviated structure follow:Data Tables-----------LeftTable1LeftID1 (int)Data1LeftTable2LeftID2 (int)Data2LeftTable3LeftID3 (int)Data3DestinationTableRightID (int)DataLinking tables option 1-----------------------JunctionTable1LeftID1RightIDJunctionTable2LeftID3RightIDJunctionTable3LeftID3RightIDLinking table option 2----------------------JunctionID1 (int)ID2 (int)ID3 (int)DestinationID (int)

Hi all, This is a bit of a general question regarding SQL Server link tables that i hope someone can find the time to answer.
I am looking for the best practice. If I have 3 tables
1) tblCompetition 2) tblTeams 3) tblTeamsInCompetition (this is the link table)
I know the link table should have a related CompetitionID and TeamID, but should the link table also have a primary key that is an identity autoincrement by 1 just as you would with the other two tables. In Access I have never done this, however in SQL Server I have read that you should do this (but now I can't find the documentation again which prompts me to ask the question here).
Thanks for taking the time to answer this question.
This seems like such a simple problem but I am new developer even through I have been on the administration end of things for some time. I will go into more detail about my tables and there relationships below. Anyway, I am trying to create a many-to-many relationship within ms sql server 2005. I have created both of my primary tables and also a junction table per the directions on microsoft's website all per ms's instructions as stated here...
At then end of these instruction it states as a NOTE: The creation of a junction table in a database diagram does not insert data from the related tables into the junction table. For information about inserting data into a table, see How to: Create Insert Results Queries (Visual Database Tools).
and these directions do not go into detail on how to do an insert on a junction table. And I cant find out how to do this anywhere on the internet... I did create a T-SQL INSERT statement in a trigger as listed below but I end up getting an error AS LISTED BELOW....
Here is how I set everything up...
PetitionSet table consists of:
PetitionSetID int auto-increment primary key PetitionSetName varchar(50) no nulls PetitionSetScope varchar(50) no nulls
the Petition table consists of:
PetitionID int auto-increment primary key PetitionSetID int no nulls PetitionName varchar(50) no nulls
the SetToPetitionJunction table consists of: PetitionSetID int PetitionID int
And, there is a composite key made up of both the PetitionSetID and PetitionID fields.
I have created the foreign key relationships with DEFAULT VALUES from the SetToPetitionJunction table to each column's respective corresponding column in each of the tables: PetitionSet and Petition.
The trigger is on the Petition table and it has the following code:
set ANSI_NULLS ON set QUOTED_IDENTIFIER ON go -- ============================================= -- Author: Name -- Create date: -- Description: -- ============================================= ALTER TRIGGER .[SetToPetitionJunctionTrigger] ON .[dbo].[Petition] AFTER INSERT AS BEGIN -- SET NOCOUNT ON added to prevent extra result sets from -- interfering with SELECT statements. SET NOCOUNT ON;
INSERT INTO SetToPetitionJunction (PetitionID, PetitionSetID) SELECT Petition.PetitionID, PetitionSet.PetitionSetID FROM Petition INNER JOIN PetitionSet ON Petition.PetitionSetID = PetitionSet.PetitionSetID
END
I have created an asp.net 2.0 front end to insert values into the PetitionSet table and the Petition Table. And in the detailsview for the Petition table I manually insert the PetitionSetID field to the number that corresponds to an auto-generated number on the primary key of the PetitionSet table. So I am maintaining referential integrity...
The first time it works and inserts one record in the Junction table containing the PetitionSetID from the PetitionSet table and the PetitionID from the petition table.
Then when I try to add in another petition for the same petition set number just like I did the first time and then I get this error...
Violation of PRIMARY KEY constraint 'PK_SetToPetitionJunction'. Cannot insert duplicate key in object 'dbo.SetToPetitionJunction'. The statement has been terminated.
Maybe this is the wrong formum but I've got a question for which you probably have the answer, i hope.
Situation ------------ John is member of Group_A and Group_B Bill is member of Group_B and Group_C Allison is member of Group_A and Group_E
How can I create a query to input Allisons username into table 1 and groupmembership into table 2. Also updating the relationship within junction-table3 must be done automaticaly. I want to avoid duplicate records. The final situation I want is given in red text.
The relationships between the tables are as follows ------------------------------------------------------------- Table1 (PK)ID-Userinfo [ONE] <------------> [MANY] Table3 ID-Userinfo Table3 (PK)ID-GroupInfo [MANY] <------------> [ONE] Table2 (PK)ID-GroupInfo
Table1: UserInfo ------------------------------ (PK)ID-Userinfo UserName 1 John 2 Bill 3 Allison
Can Somebody please show me how to acheive this, using the order details in Northwinddatabase or any other good example. as much details as possible. Many Thanks!
For example,I have a table "authors" with a column "author_name",and it has three value "Anne Ringer,Ann Dull,Johnson White".Here I want to create a new table by using a select sentence,its columns come from the values of the column "author_name".
can you tell me how can I complete this with the SQL?
I'm designing a database with 3 tables called Function, Test andScene.A Function has multiple Tests, but a Test has only one Function. Amany to many relationship exists between Test and Scene therefore Ineed a junction table between these two tables - giving 4 tables intotal. The Test table would store a foreign key, the primary key ofthe Function table.There is a problem with design though and that is that Functions andScenes are actually defined before the Test is defined. Therefore itshould be possible to create a Function and add to id its Scenes,before Tests have been defined. In other words, Scenes are as much apart of a Function as they are of Tests. Tests are in fact only ofrelavence to testers. Anyway, to satisfy this scenario, a Junction boxis also needed beween Function and Scene. This creates a loop betweenall tables.Is this a good approach? Any other suggestions or advice on thematter? Any advice regarding data integrity?Thanks,Barry
So, I need to delete the "timestamps" the an user has done, which the difference between one stamping and the following one is less than 2 minutes for the inputs for entrances and I need to remove it when the "stampings" which the difference between an one stamping and the previous one is less than 2 minutes for exits.
Can you help me please? I will appreciate a lot your help.

I'm using the sentence NOLOCK for selects, but I have many sentences, Is there any way to set a parameter in the DBMS, to use NOLOCK parameter by default ???? I mean, I don't like to lock any table for selects.
Hi, all friends.

i have insert/update SQL sentence, but sometimes there are empty values because there not required in the database so sometimes the sql sentence look this way:
INSERT INTO EquipmentAndPlace (EquipmentID,EquipmentEmdaNo,EquipmentPlace,EquipmentIDForRecognize, EquipmentRemarks,EquipmentLastChecked) VALUES ('3','','2','1','','12/1')
with empty values, but then it doent update in the dataBase-only if all the values appear- what the solution of it? Thanks
I would like to know how can I change a "not in" clause with the same results in a SQL sentence in order to improve the performance of my SQL sentence.
I want to add a parameter to the following SQL-sequence. ActivityGroup is the table and I want to select the current activityGroupID in place of XXXXX. Do I need to put this in a stored procedure?

I have a project in which I have about 20,000 records in sql database table.
What I would like to do is generate a query that lists all the unique words in a particular field acros the entire table so as to generate a glossary of words.
if we had a table that looked like
ID Description
001 This is the first record
002 This is the second record
003 This is not the first record
and the query was run on the description field, then the result I would like to see is
This is the first second not I hope this makes sense. Any help is appreciated.
My MASTER table that contains text is very simple: TEXT_ID INT TEXT varchar
I was thinking of something like creating another table to keep track of selection criteria: USER_NAME varchar // keeps track of which user made the selection TEXT_ID INT // points to the text id in the MASTER table START_POS INT // start position of the selection END_POS INT // end position of the selection COLOR INT // color of the selection
The thing I don't like about this method, is if user(s) have many words higlighted in the sentences, this table may get very large.
I also thought of maybe combining START_POS, END_POS & COLOR into comma delimited entries:
EX: 1:5:240, 25:30:125 // START_POS:END_POS:COLOR
The thing I don't like about this method, the parsing calculations may take a while to execute.
My goal is to stream as much text data as possible and make it as fast as possible. How does Google or any one else do it?
P.S. Having a copy of a MASTER table with HTML tags in TEXT field is not an option.
I have to parse a sentence into separate words. This has to be done in a Stored Proc.
If the sentence is: "The sun is rising". Then I want to store the words "The" "sun" "is" "rising" into 4 separate variables. (The separator is a space).
Has someone already written something like this before? I do not want to re-invent the wheel.

Hi everyone!I am working with Delphi v7 and MS SQLServer.I am trying to insert data in a table with a SQL sentence. Some of thefields of my table are type char or varchar, and they can have nullvalues.What do i have to write in the SQL sentence to insert a null value inthose fields?I tried with '', an empty String, but it doesnt work, the tablesstores an empty String (logical :-)).In the SQLServer GUI you have to press CTRL + 0 to insert a NULLvalue, but how can i tell this to the SQLServer through a SQLSentence?Well, thank you very much.
I was recently told SSRS does not support the ability to underline a portion of text in a sentence. Does anyone know if this is true? Couldn't "text decoration" "underline" and "span" be used to underline the web address in the sample sentence below?
