Muliple primary keys
Help, please.
I'm pretty new to access and I'm stuck. I created a database for my school. I have a table of course who has information on courses such as #, section, term, period, course description and name of the teacher of the course. The primary key of this table is: #, section, time and class period. (when these four elements are combined, it creates a unique identifier).
Then I have another table that has course ID #, section, term, time and student.
My problem: how to create a query that the combination of all this information. In other words, how do I know the query to list all the info of course, with name ID and teacher of the student, but only if the course #, section, duration and period match?

This forum is for Windows 8, so your question is really off-topic
Here you would be also much better ask in a forum access, since

MySQL Insert with autoincremented primary key
I did not before MySQL. I try and hit a roadblock soon enough.
I would like to insert new records and have the auto-generated primary key / auto-increment.
So, I have attached a few screenshots. The first is a screenshot of the MySQL settings for the table that I'm writing. The second is the Labview code that I threw as well as I am trying to run.
The complete of the error I get is:
> Database Connection.vi
ADO error: 0x80004005
Exception occurred in the Microsoft OLE DB provider for ODBC drivers: [MySQL] [ODBC 3.51 Driver] [mysqld - 5.7.11 - log] field 'techniciansID' didn't is not a default value to create a NI_Database_API.lvlib:Rec - Command.vi-> NI_Database_API.lvlib:Cmd Execute.vi-> NI_Database_API.lvlib
Data.vi B tools insert-> Connection.vi in the databaseI know that this error indicates that the techniciansID has no default value and he won't write because of it... but since it is an AutoIncrement field, it seems like it should work.
Any help would be appreciated. Thank you

Setting to 0 did not work, but I understand it. For some reason any when I was refreshing my tables in MySQL server and using the "Forward Engineer" feature, the changes were not multiplication. I had to drop the schema of the database (attached image) and then do an "engineer forward." I made the changes, but the tables and the columns still had the attributes of origin... guess they cannot be updated by the script during execution.
After doing this and the original settings I had (autoincremented primary key), the insert works in MySQL and Labview.
Thanks for all the answers. They made me think and check some things I didn't have before.

Make required error appears only the primary key generated in prior Database Table insert trigger
Dear all,
I am a beginner in the ADF and am under Jdeveloper Studio Edition Version 12.2.1.0.0.
I'm trying to insert a record, I created the trigger for insertion prior to get the primary key and set some other default values.
On the page, I did read-only primary key column and false required.
When I try to save - commit (Programmatic), I get errors for the required value. How can I stop this errors.
Secondly, I also tried changing the agent to disabled on the attribute View object that raised the error below:
< oracle.dfw.impl.incident.DiagnosticsDataExtractorImpl > < DiagnosticsDataExtractorImpl > < createADRIncident > < incident created 148 to key problem "DFW-99998 [oracle.jbo.PersistenceException] [oracle.jbo.server.RowReference.verifyPrimaryKeys] [Proposals]" >
Hoping for help.
Thanks and greetings

If the primary key values from DB sequence, you can follow this approach:
Using the sequence of database in ADF - Souza Waslley Blog
Oracle Fusion Middleware Technologies: ADF 11 G: generate the primary key sequence number
Otherwise, instead of DB trigger, create the DB function that retrieves the value of the PK and call stored function in the overloaded method create() entity:

Forgive my question. I am very new to Oracle.
How can I make sure that changes in the key primary supplier_id (concerning the supplier table) would also appear directly in the FOREIGN KEY (supplier_id) in the products table?
Is that not all the primary key and FOREIGN KEY on?
My paintings:
I created 2 tables and connect to apply in the data base referential integrity, as I learned.
CREATE TABLE - parent provider
(the numeric (10) of supplier_id not null,)
supplier_name varchar2 (50) not null,
Contact_Name varchar2 (50).
CONSTRAINT supplier_pk PRIMARY KEY (supplier_id)
);
CREATE TABLE - child products
(the numeric (10) of product_id not null,)
supplier_id numeric (10) not null,
CONSTRAINT fk_supplier
FOREIGN KEY (supplier_id)
REFERENCES beg (supplier_id)
);
I inserted the following text:
INSERT INTO provider
(supplier_id, supplier_name, contact_name)
VALUES
(5000, 'Apple', 'first name');
I expect that the supplier_id (5000) to the provider of the table also appears in the products table under key supplier_id having the same value which is 5000. But this does not happen.
How to get there?
Thanks in advance!
Hello
What is a foreign key in Oracle?
A foreign key is a way to ensure referential integrity in your Oracle database. A foreign key means that the values of a table must appear also in another table.
Ok!??
What is now the right way to implement referential integrity in your Oracle database that the values of a table must also be included in another table?
A foreign key referential integrity indeed enfore in ensuring that the value in the child table must have a corresponding parent key (otherwise you will encounter an error, as evidenced by "SomeoneElse"). However, it will never automatically insert a row in the other table.
If you are looking for a solution that automatically inserts a record in the other table, maybe you should go for triggers:

Hi all, finally I found the solution to this exception.
I did the following steps to solve the problem.
1. create a bean and use this method
public void tooManyObjectsMatchExceptioHandeler() {}
Add the code in the event here...
System.out.println ("inside the Handeler");
FacesMessage message =
new FacesMessage ("Type your friendly message");
message.setSeverity (FacesMessage.SEVERITY_ERROR);
FacesContext fc = FacesContext.getCurrentInstance ();
fc.addMessage (null, message);
}
Now, drag and drop the file above java projects in data controls in the browser of the application.
2. drag a workflow method call (where u get exception as Houston-25013) and call this method as an activity of the exception handler,
Now, do a right click on this--> definition of the page method call create or go to definition of the page--> create a link Action method and select the above method in the select and file def page this method call in the workflow then go to properties inspector set out fixed property (here name of activities of method call) u give.

What is the difference between primary key and unique indexes with forced not null?
Primary key is = unique index + not null?
The short answer is Yes.
However, even if the primary key, applying both uniquness and not null, there is a notion of "special".
You can only have one primary key in tables, but you can have multiple unique indexes and constraints not null.
See: https://asktom.oracle.com/pls/asktom/f?p=100:11:0:P11_QUESTION_ID:8743855576462

Another user changed the row with a primary key oracle.jbo.Key]
I see many discussions about this error, but still cannot understand the difficulty that I need in my scenario.
I am an Oracle Developer and completely new to ADF, please bear with me.
I use JDeveloper 11.1.1.9.0
My scenario:
Creates an object editable view (UVO) with sub selects in the query, which is from several db tables.
Creating a table using the UVO
When I try to update a field in the table, and then click the validate, I get the error message:
Another user changed the row with a primary key oracle.jbo.Key]
Can someone explain in what scenarios I see this error and how do I solve this problem?
Try the viewObject execution after validation and reQueryOnCommit set to true
For details see - binary: a reason more for "Houston-25014: another user has modified the line containing oracle.jbo.Key primary key '

Hello
Actually I got to know this update of a record must be made when the primary key is based on two columns.
Previously, I used SPEL for a column. It was working fine.
But I came to know that regardless of the folder I try to update, it was the update page is coming up with the first combination of the record.
As if RC 131
RC 124
RC 125 are the records.
If I click on update of RC 124 also, the update page is coming up with RC 131 values as it is the first.
So I understand that the SPEL should be based on two parameters, because it is a composite key.
How to do?
Please let me know if you don't understand the problem.
Thank you.
Wow!
I got it.
Thank you brothers, always a hope that you could help me

How to delete several lines in the details Table with PRIMARY KEY = ("VID", "LINEITEM")?
Mr President
My worm Jdev is 12.2.1.
I have master tables / details.
I have 2 lines for each PRIMARY KEY = ("VID", "LINEITEM") as below in the Details table.
Please help how to get a button on a jsf page to remove these two lines at a time.
Concerning
So, in your app (data model) module, you have a master relationship / typical retail:
And the relationship between them is based on some ViewLink
Now go to the ViewLink, relationship, accessor.
Take a look at the Destination accessor.
Generate accessor object to check and give a name Acessor
Then go to the master VO, Java and Include accessor, the class generate a display line:
Go to the class view Java generated line, you'll find a method with the name of the accessor of the previous step, in the form of:
public RowIterator getYourDetails...or_whaterever_IsAccessorName..() { }Now, in the same Java class, write the following Java method:
public void removeDetails(){ RowIterator details = getYourDetails...or_whaterever_IsAccessorName..(); // it is RowIterator over all details Row r = details.first(); while (r != null) { r.remove(); r = details.next(); } }This method on the Cilent export line Interface:
Finally, pass the data controls and drop this operation on the form as a button...

Concerning
You can't repeat the value of pharmacokinetics in several lines. try to follow this:
1. in your database to create new sequence "PK_SEQ".
2. in doDML write this
if (operation == DML_INSERT) { SequenceImpl seq = new SequenceImpl("JOIN_SEQ", getDBTransaction()); oracle.jbo.domain.Number seqValue = seq.getSequenceNumber(); setJoinColumn(seqValue); setPKey(getPkSeqNextNumber()) insertSecondRowInDatabase(getPkSeqNextNumber(), getColumn1(), getColumn2(), getColumn3(), getJoinColumn()); }the getPkSeqNextNumber will be
private Number getPkSeqNextNumber() { SequenceImpl pkSeq = new SequenceImpl("PK_SEQ", getDBTransaction()); return pkSeq.getSequenceNumber(); }or
You can do a trigger in the database, this trigger Gets the value of the sequence and sets the pkey to insert before

Another user has modified the line containing oracle.jbo.Key [186 primary key].
as summer sees in this photo, when I click on the button to edit, it will invoke the code like this:
BindingContext bcxt1 = BindingContext.getCurrent ();
DCBindingContainer bc1 = (DCBindingContainer) bcxt1.getCurrentBindingsEntry ();
DCIteratorBinding iterProj = bc1.findIteratorBinding("CuxProjects1Iterator");
DC DCDataControl = iterProj.getDataControl ();
ApplicationModule am = (ApplicationModule) dc.getDataProvider ();
ViewObject projVO = am.findViewObject("CuxProjects1");
projVO.clearCache ();
projVO.setNamedWhereClauseParam ("project", currProjId);
projVO.executeQuery ();
got this page with changes on the name of the project:
then click on 'done' button.invoke a procedure like this:
State channel = null;
DBTransaction connection BD = this.getDBTransaction ();
CallableStatement st =
BD connection.createCallableStatement ("start cux_projects_crud.update_proj(?,?,?,?,?,?,?); end; ", 0) ;
try {}
st.setInt (1, proId);
st.setString (2, proName);
st.setString (3, proSummary);
st.setDate (4, null);
st.setDate (5, endDate);
st.setInt (6, userId);
st.registerOutParameter (7, Types.CHAR);
st.executeUpdate ();
State = st.getString (7);
Then return to the first page as the top image.
My problem is not rested but redesigned data into DB. When I click on the button to edit again, I get ' javax.faces.el.EvaluationException: oracle.jbo.RowInconsistentException: Houston-25014: another user has modified the line containing oracle.jbo.Key [186 primary key].» This error. How to solve this problem?
In addition, I see a problem that the changes you make in the procedure are not validated and will not be picked up by the query.

Trigger - use one to create primary key values
I'm stuck on a simple use to do a TRIGGER that fires when you add new rows to a table and want to Developer SQL to add the primary key value.
I seem to be able to relax, but it is not inserted the primary key but giving a SQL error: ORA-00947: not enough values.
Here's what I have.
CREATE TABLE HF_fishers
(
contact_id INT NOT NULL
, name VARCHAR (25)
, last_name VARCHAR (35)
PRIMARY KEY (contact_id)
);
CREATE SEQUENCES HF_fishers_seq.
Then I ran the following trigger:
CREATE
HF_fishers_seq_trigger RELAXATION
BEFORE INSERTING
ON HF_fishers
FOR EACH LINE
BEGIN
IF (: new.contact_id IS NULL)
THEN
: NEW.contact_id: = NVL (: NEW.contact_id)
HF_fishers_seq. NEXTVAL
);
END IF;
END HF_fishers_seq_trigger;
=============
Then I executed the following SQL statement that gives the error.
INSERT INTO HF_fishers VALUES('Jacob','Muller');
But if I do everything is good except that it defeats the purpose of relaxation.
INSERT INTO HF_fishers VALUES(1,'Jacob','Muller');
MySQL has a nice 'AUTO_INCREMENT' command, but from what I understand in Oracle, I need to set up a trigger to automatically increment a column/cell, which in this case I use for the PRIMARY KEY.

OK Jaramillo, I tried as you wrote, but what would be an INSERT statement correct?
-After the code trigger of Jaramillo
INSERT INTO HF_fishers (first_name, last_name) values ("Jesse", "Owens"); -I have the trigger but he made the mistake of duplicate key.
INSERT INTO HF_fishers values (hf_fishers_seq.nextval, 'Jesse', "Owens"); -No trigger but get key duplicated,.
INSERT INTO HF_fishers VALUES(:NEW_contact_id,'Jesse','Ownes'); -works without the trigger but the "get links" dialog box appears. So not much 'automatic' on this issue,.
My mistake. Here is the modified version of the trigger. I removed the CONDITIONAL clause and comes to be a part of the body of the trigger.
So, I created the table, the sequence, the relaxation and ran the first two insert statements and it worked fine. The third one you have invites SQL + or any tool you use to enter a value if she sees the ":" colon as a variable binding. Colon only works in a trigger without asking for confirmation.
Here is the code and my exit I ran home
DROP TABLE hf_fishers CASCADE CONSTRAINTS PURGE; DROP SEQUENCE hf_fishers_seq; CREATE TABLE hf_fishers ( contact_id INTEGER NOT NULL ,first_name VARCHAR(25) ,last_name VARCHAR(35) ,PRIMARY KEY (contact_id) ); CREATE SEQUENCE hf_fishers_seq; CREATE OR REPLACE TRIGGER hf_fishers_seq_trigger BEFORE INSERT ON hf_fishers FOR EACH ROW BEGIN IF(:NEW.contact_id IS NULL) THEN :NEW.contact_id := hf_fishers_seq.NEXTVAL; END IF; END hf_fishers_seq_trigger; INSERT INTO hf_fishers(first_name, last_name) VALUES ('Jesse', 'Owens'); -- Works with the trigger INSERT INTO hf_fishers VALUES (hf_fishers_seq.nextval, 'Jesse', 'Owens'); --Works without using the trigger body code.

Hello
I am trying to open the Console of the IOM of Sysadmin,
try checking the research,
search specific "Lookup.USR_PROCESS_TRIGGERS".
and get the error on the screen
Houston-25013: too many objects match the [primary key Lookup.USR_PROCESS_TRIGGERS USR_EMP_TYPE] oracle.jbo.Key.
This known issue?
This patch it for it?
tried searching discussion forums, nothing here
Thank you
Check from the console design. Looks like you have a duplicate key Code value.
