How to create query for tables with many to many relationship

in my sql i'm unable to update the table using select clause...is there any way to update a table which is in many to many relationship.
Ex:1st table student(student_id int primary key auto_increment, student_name varchar(30));
2nd table contact (contact_id int primary key auto_increment, c_email varchar(40));
3rd table student_contact(student_id int references student, contact_id int references contact);
i would like to auto insert the both two columns in the student_contact while the student and the contact table being updated automatically.

This is a JSP/JSTL forum, not a SQL forum. If you're using MySQL, better use their own forums at dev.mysql.com.
I'll give some hints anyway: learn about SQL JOIN. In general there is good SQL documentation available at the website of the RDBMS manfacturer. Go check it out. There is also a nice SQL tutorial at w3schools.com. Good luck.

How to create variant for table/view ?

Hi,
When I go through SM30, I find a radio button called variant. I don't know the effect.
Can anyone tell me how to create variant for table / view ?
I want to know when we need to create variant for table/view.
Best regards,
Chris Gu

hi ,
Whenever you start a program in which selection screens are defined, the system displays a set of input fields for database-specific and program-specific selections. To select a certain set of data, you enter an appropriate range of values.
For further information about selection screens, refer to Selection Screens in the ABAP User's Guide.
If you often run the same program with the same set of selections (for example, to create a monthly statistical report), you can save the values in a selection set called a variant
Procedure
To create a new variant:
       1.      On the ABAP Editor initial screen, enter the name of the program for which you want to create a variant, select Variants, and choose Change.
       2.      On the variant maintenance initial screen, enter the name of the variant to be created.
Note the naming convention for variants (see below).
       3.      Choose Create.
If the program has more than one selection screen, a dialog box for screen assignment appears. The dialog box does not appear if the program only has one selection screen. The selection screen appears in this case.
       4.      If there is more than one selection screen, select the screens for which you want to create the variant
5.      Choose Continue.
The (first) selection screen for the report appears.
If your program has more than one selection screen, use the scroll buttons in the left-hand corner of the application toolbar to navigate between them and to fill the fields with values. If you keep scrolling forwards, the Continue button appears on the last selection screen.
       6.      Enter the desired selection values, including multiple selection and dynamic selection.
       7.      Choose Continue.

How to Create a Temporary Table with SQL Server

I know you can create a temporary table in SQL Server 2000, but not quite sure how to do it in CFMX 7, i.e., does the SQL go inside a <CFQUERY dbtype="query"> tag?
I'm pulling the main set of records from an Oracle server (1st data source), but it does not contain employee names, only employee IDs. Since I need to show the employee name along with the Emp ID, I'm then pulling a list of "current" employee names from a SQL Server (2nd data source), which is the main database on our CF server.
I've got a QofQ that works fine, except it only matches EmpIDs that exist in both result sets. Employees who are no longer employed, don't match, and don't display. Since I can't do a LEFT OUTER JOIN with a QofQ, what I need to do is get the records from the Oracle server into the SQL Server. Preferably in a temporary table.
I was hoping if I could get those Oracle records written to a temp table on the main SQL Server, in same database as the Employee Name table, I could then write a normal <CFQUERY> that uses a LEFT OUTER JOIN.
I think I could probably write a Stored Procedure that would execute the SQL to create the temporary table, but am trying to avoid having to write the SP, and do it the simplest way.
This query will be a program that can be run hundreds of times per day, with a form that allows users to select date ranges, locations, and other options. That starts the queries, which creates the report. So I just need the temp table to exist only until all the SQL has run, and the <CFOUTPUT> has generated a report.
If the premise is right, I just need some help with the syntax for creating a SQL Server temp table, when you want to write records to it from an external data source. I'm trying the following, but getting an error:
<CFQUERY name="ITE_Temp" datasource="SkynetSQL">
CREATE TABLE #MyTemp
( INSERT INTO #MyTemp
ITE2.TrueFile char (7) NOT NULL,
ITE2.CountOfEmployee int NULL,
ITE2.DTL_SUBTOT decimal NULL,
ITE2.EMPTYPE char (3) NULL,
ITE2.ARPT_CD char (3) NULL
</CFQUERY>
So I actually created a permanent table on the SQL Server, and wrote the below SQL, which does work, and does write the records to table. I can then write another CFQUERY with a LEFT OUTER JOIN, and get all the records, including those that don't have matching employee name:
<CFQUERY datasource="SkynetSQL">
<CFLOOP index="i" from="1" to = "#ITE2.RecordCount#">
INSERT INTO ITE_Temp
 (FullFile,
 EmployeeCount,
 DTL_Amount,
 EmployeeType,
 station)
VALUES ('#ITE2.TrueFile[i]#',
 #ITE2.CountOfEmployee[i]#,
 #ITE2.DTL_SUBTOT[i]#,
 '#ITE2.EMPTYPE[i]#',
 '#ITE2.ARPT_CD[i]#')
</CFLOOP>
</CFQUERY>
But, I hate to have to create a table and physically write to it. For one, it seems slower, and doing it in temp would be in memory, and probably much faster, correct? Is there some way to code the above, so that it does something similar, but in a TEMPORARY TABLE? If I can figure out how to do this, I can pull data from multiple data sources and servers, and using SQL Server temp tables, work with the data as if it was all on the same SQL Server, and do some cool reports.
Everything I've done for the past few years, has all been from data from a single source, whether SQL Server, or another server. Now I need to start writing reports where data can come from 3 or 4 different servers, and be able to do joins (inner and outer). Thanks for any advice/help. Much appreciated.
Gary

While waiting to hear back, I was able to write the query results from an outside Oracle server, to a table on the local SQL Server, and do the LEFT OUTER JOIN required for the final query and report to work. That was with this syntax:
<CFQUERY name="AddTableRecords" datasource="MyTable">
TRUNCATE TABLE ITE_Temp
<CFOUTPUT query="ITE2">
INSERT INTO ITE_Temp
(FullFile,EmployeeCount,DTL_Amount,EmployeeType,station)
VALUES
('#TrueFile#', #CountOfEmployee#, #DTL_SUBTOT#, '#EMPTYPE#', '#ARPT_CD#')
</CFOUTPUT>
</CFQUERY>
However, I was not able to write to a temporary table AND read the results. I got the syntax to run to write the above results to a temporary table. But when I tried to read and output the results from the temp table, I got an error. Also, it wouldn't take the single "#" (local) only the global "##" table var, using this syntax. Note that if I didn't have the DROP TABLE in the beginning, the 2nd time you run this query, you get an error telling you the table already exists.
<CFQUERY name="ITE_Temp2" datasource="MyTable">
DROP TABLE ##MyTemp2
CREATE TABLE ##MyTemp2
FullFile char (7) NOT NULL,
EmployeeCount int NULL,
DTL_Amount decimal NULL,
EmployeeType char (3) NULL,
station char (3) NULL
<CFOUTPUT query="ITE2">
INSERT INTO ##MyTemp2 VALUES
'#ITE2.TrueFile#',
#ITE2.CountOfEmployee#,
#ITE2.DTL_SUBTOT#,
'#ITE2.EMPTYPE#',
'#ITE2.ARPT_CD#'
</CFOUTPUT>
</CFQUERY>
So even though the above works, I could use some help in reading/writing the output. I've tried several things similar to below, but they don't work. It't telling me ITE_Temp2 does not exist. It's not easy to find good examples of creating temporary tables in SQL Server.
<CFQUERY name="QueryTest2" datasource="SkynetSQL">
SELECT *
FROM ITE_Temp2
</CFQUERY>
<CFOUTPUT query="ITE_Temp2">
Output from Temp Table 
FullFile: #FullFile#, EmployeeCount: #EmployeeCount#
</CFOUTPUT>
Thanks for any help/advice.

How to create an internal table with fields from different sources

Hi.
I need to create an internal table where some of the fields are from a database table, and the other fields are user specified. How do i do that?
Example:
DB table ZTAB with fields ZTAB-FIELD1, ZTAB-FIELD2.
I want to create an internal table ITAB with the fields ZTAB-FIELD1, ZTAB-FIELD2 from ZTAB. In addition, I also want to have one more field RECORD_NO, which is not from ZTAB. How do I do it? Could I do something like below?
DATA BEGIN OF ITAB.
        INCLUDE STRUCTURE ZTAB.
DATA RECORD_NO TYPE I.
DATA END OF UPLINE.
Or, are there more efficient way of doing it? Thanks.

hi KIan,
go:
general type
TYPE : BEGIN OF ty_itab,
           field1 TYPE ztab-field1,
           field2 TYPE ztab-field2,
*your own fields here:
           field TYPE i,
           field(30) TYPE c,
           END OF ty_itab.
work area
DATA : gw_itab TYPE ty_itab.
internal table
DATA : gt_itab TYPE TABLE OF ty_itab.
hope this helps

How to create an internal table with a types structure?

Hi experts,
I've 3 internal tables with the same structure, I think I could put a type structure and put that type inside the body of the internal data, is this possible? If true, how can I put that?
Example:
TYPES: Begin of type_s,
               pernr like pa0001-pernr,
             end of type_s.
Data: begin of itab_1 occurs 0,
¿¿¿??? reference to type_s
         end of itab_1.
Thanks a lot,
Regards,
Rebeca

Hi,
Use like this..
DATA: Begin of type_s,
pernr like pa0001-pernr,
end of type_s.
DATA: BEGIN OF ITAB_1 OCCURS 0.
INCLUDE STRUCTURE type_s.
DATA: END OF ITAB_1.
Otherwise like this.
types: Begin of type_s,
pernr like pa0001-pernr,
end of type_s.
Data: itab_1 type standard table of type_s.
Note: You have to create work area explicitly.
Like this
data wa like itab1.

You have the right link to get started on adding authentication to your Mobile service app. But for security reasons the MobileServiceUser class only exposes the authenticated UserId and MobileServiceAuthenticationToken properties. You can save these
two values in your client application.
Getting the user name and email address isn't available through this medium. You would have to call into the respective APIs for the service (Facebook or Twitter APIs).

How to create Rows in Database with EJB3.0 Entities - Relationship Problem

Hi,
I don't have much experience in writing Entity Java Beans, so if some questions are "dummy-questions", I apologize for that.
Actual state: I have implemented Entity Java Beans with relationships between them. I can deploy them to JBOSS AS and everything is fine. Then, I want to implement a small client to fill the database with some values to check if my Beans are correct.
Problem: I have three Beans, that have relationships.
Entity Flight, Entity FlightSeat and Entity Address
Flight has a OneToMany relationship with FlightSeat and two ManyToOne relationships with Address (for start- and destinationaddress of the flight)
No, I want to create Values in the database with the Entities, but I don't know how I have to conside the relationships. How can I add a Flight row to the database? Do I have to specifiy the start- and destinationaddress, when saving the entity Flight with Entitymanager.persist()?? Maybe you know a good Tutorial where I can see, how it is possible to fill the tables?

Understand that virtual directories are not exactly the same
thing as
virtual hosts.
A virtual directory will not act as the root for a site. IIS

still think that your site root is the overall IIS site root.
There are some utilities that allow you to switch the folder
that IIS
uses as the root. This one works pretty well:
