ORA-02270 / No Matching Unique Or Primary Key For Column-list
Jan 14, 2013
I'm trying to make a foreign key against a table which has a unique index instead of a primary key.
i get this error:
Error SQL: ORA-02270: no matching unique or primary key for this column-list
02270. 00000 - "no matching unique or primary key for this column-list"
*Cause: A REFERENCES clause in a CREATE/ALTER TABLE statement gives a column-list for which there is no matching unique or primary key constraint in the referenced table.
my question is (i've searched several times with no results) can i create a foreign key with a table wich has no primary key but a unique index ?example:
or TABLE1.IDTABLE1 must be a 'Primary Key' instead of unique index ?I know it should be primary, but i need to know if it would work with the index somehow. The reason is i'm migrating a large database and the original structure in mysql uses fk with indexes and no pks in some tables (48 to be precise)
I was cloning a schema user1 as user2 in the same database.
user1 had quota on 2 tablespaces user1_data and user1_index.
I created user with name as user2.
I created tablespace user2_data only and granted user2 unlimited quota on that tablespace only (did not grant him 'resource' role or unlimited tablespace privilege) Now exported user1 schema as follows
during import i encountered following errors for so many constraints
"ALTER TABLE "table2" ADD CONSTRAINT "constraint_name1" FOREIGN KEY ("CTR_ID") REFERENCES "table1" ("CTR_ID") ENABLE NOVALIDATE" IMP-00003: ORACLE error 2270 encountered ORA-02270: no matching unique or primary key for this column-list IMP-00017: following statement failed with ORACLE error 2270:
I found that the it happened as the primary key of table1 was not created for which error was logged in the log file
. . importing table "table1" 19441 rows imported IMP-00015: following statement failed because the object already exists: "ALTER TABLE "table1" ADD CONSTRAINT "T1_PK79" PRIMARY KEY ("CTR_" "ID") USING INDEX PCTFREE 10 INITRANS 2 MAXTRANS 255 STORAGE(INITIAL 65536 F" "REELISTS 1 FREELIST GROUPS 1) TABLESPACE "USER1_INDEX" LOGGING ENABLE " . . importing table "table5" 0 rows imported
However, I checked that the T1_PK79 does not exist in the user2 schema though it exists in user1 schema Neither the index for priamry key (T1_PK79) existed in user2 schema not the table <table1> existed before this import Then what could be the reason that I am getting an error "IMP-00015: following statement failed because the object already exists"?
I assume tablespace for index would not be an issue here as other indexes got created properly in user2_index tablespace during this import.
I tried this twice, once with user2 schema and then with user3 schema as well (with different tablespace), but result is the same.
There were no users connected to the database during export and no background jobs were modiying any data in schema user1 while export.
what is the matching datatype of unique identifier in SQL to Oracle ques regd SSIS when I map a unique identifier in SQL to Oracle via SSIS, I get curly braces at both ends in the end result.
1B66FE97-A9CA-4E0D-9593-00046E2AF7E1 - i/p(SQL Server) {1B66FE97-A9CA-4E0D-9593-00046E2AF7E1} - end result(Oracle)
In SSIS, I convert the unique identifier to string data type.
I have a 'Select List' widget (P_FILTER) which I have set to return multiple values. In my report region, I have something like this
Select A from B where B.Col_1 IN upper(:P_FILTER)
When user selects only 1 value, the report is correct but if user selects more than 1 value (e.g. 2), the report does not return any rows. How do I get the report to recognize the multiple values returned by the LOV?
I have in a plsql block somewhere a statement like
INSERT INTO TABLE1( id , col) SELECT id, col FROM TABLE2;
This statement returns an error ORA-00001: unique constraint because id is a primary key on TABLE1. I would like to know what is the value of id that raised the exception.
I have two design alternatives and need to understand how expensive (speed) is one of them against the other for a medium size table (100K-200K records):
create table xyz ( f1 number not null, f2 varchar2(20) not null, f3 number not null, f4 varchar2(50),
[code]....
the idea is to optimize the design by using a PK instead of the 3 keys and there is a debate that searching a unique index field(2nd scenario) is of the same speed than searching a PK field (1st scenario).
find the below task. I have unique schemas. and every schema we have many tables.I would like to know
1. I have Scott schema and here I have 10 tables. EMP,DEPT,SALGARDE ( and these tables having different priviliges).
2. another schema MACIN having table DEPT, SALS, GRADE ( having different priviliges) Now I would like to know Schema 1 having permissions to see the tables and he is doing some modifications,inserting,deleting .... on tables containing in MACIN schema.like this it is happening in vice verse in max schemas. now I would like to know who all are having access to login to another schema and what are the priviliges they have till now on what tables they applied changes...is it possible to figure out? if yes how can we?
How can I create a list of items in a field, for instance lets say I have a table called car and one of the sub categories is parts. How can I make it so that parts can be any number of pre-defined entities? Or even table, for instance if I make a table called parts how can I use that in the car table in place of parts?
My second question is about using foreign keys as primary keys. If I am writing an email sql DB and I decided to use the members usrname as the primary key in the member table but then made another table that lists all the emails and decided to make the foreign key member username the primary key there.
Is that safe to do or should i create a sequence in which to identify a primary key for the email list table? Also what if I extend member to several other tables and use it as a primary key there too, seems like a kind of dangerous way to do things...
I am having issue with Oracle reserved words, one of the application is using table which has NUMBER as column. I am not able to query that table matching database with NUMBER column.
HERE
select a.* from DOC a , FOLDER B where a.NUMBER= B.INCIDENT_ID and b.open = 'Closed'; I tried double quotes (“”) and sigle quotes too, none of them worked.
SQL > CREATE UNIQUE INDEX index_debug1 ON debug_table (SLNO);
Index created.
SQL > ALTER INDEX index_debug1 ADD COLUMN MESSAGE; ALTER INDEX index_debug1 ADD COLUMN MESSAGE * ERROR at line 1: ORA-02243: invalid ALTER INDEX or ALTER MATERIALIZED VIEW option
I can't create a unique constraint on these columns because there are many null values for column colX, and as mentioned, when colX is null, colY and colZ can be any values.
I also tried using a before insert trigger to find duplicates before posting and raise an error if found, but this causes an ORA-04091 mutating error since the trigger in the table is referencing itself to check for duplicates.
Also, I know there is something called a function based index, but I cannot use those with my code, so I need another solution if possible.
I have a table DN_ACTIONS with 9.5 million records. Column DA_OBJECT_NAME is not unique and same object name can have multiple entries. Column DA_ACTION_STATUS can have any values between 1 to 5.
I want to find all the DA_OBJECT_NAME in DN_ACTIONS where all of its entries has DA_ACTION_STATUS=3.
best way as it does a self join on big table of 9.5 million.
(select distinct a.DA_OBJECT_NAME from DN_ACTIONS a where not exists ( select distinct DA_OBJECT_NAME from DN_ACTIONS b where a.DA_ OBJECT_NAME = b.DA_OBJECT_NAME and b.DA_ACTION_STATUS != 3))
I am facing a problem in leave_form report! want to show employee's previous leaves detail (leavedate,leavetype), i don't want to show leavetype 'PPP' repeating frame type is Across/Down, there are 22 records of leavetype 'PPP' and one record of leavetype 'CL'
problem is report is showing 22 records of leavetype 'CL' of same leavedate!
i want that report should show the actual leavedate and leavetype records.using 9i database 6i developer server2003
For leavetype
FUNCTION Cf_1formula RETURN CHAR IS v_leavetype CHAR(40); BEGIN SELECT LT.description INTO v_leavetype FROM hrm_attendance L, hrm_leavetype LT, hrm_employees E [code]....
emp_id number, name varchar2(30), from_dt date, remarks varchar2(60)
insert into MY_TAB values (1,'TOM','01-JAN-13', 'some remark'); insert into MY_TAB values (1,'TOM','02-JAN-13', 'some remark'); insert into MY_TAB values (2,'TOM','01-JAN-13', 'some remark'); insert into MY_TAB values (3,'TOM','01-JAN-13', 'some remark'); insert into MY_TAB values (4,'TOM','01-JAN-13', 'some remark'); insert into MY_TAB values (4,'TOM','02-JAN-13', 'some remark');
How do I ensure that when a user tries to insert record with emp_id as 1, then he should only be allowed to enter another from_dt but the value in the name column have to be the same as in the previous row of emp_id 1.
insert into MY_TAB values (1,'TOOM','03-JAN-13') --shld not be allowed.
I have created a table and i have a column consisting of 1000 records (but where i have duplicates). And now i want to create a primary key for the column.
Using Oracle 11g, below is the table, partitions, unique and non-unique local index:
CREATE TABLE DOCA( DOCA_ID NUMBER NOT NULL , DOCA_BKG_PAX_ID NUMBER NULL , ROW_PURGE_DATE DATE NULL ,)PARTITION BY RANGE(ROW_PURGE_DATE)INTERVAL(NUMTOYMINTERVAL(1, 'MONTH'))( PARTITION P2007 VALUES LESS THAN (TO_DATE('01/01/2008', 'dd/mm/yyyy')), PARTITION P200801 VALUES LESS THAN (TO_DATE('01/02/2008', 'dd/mm/yyyy')),) TABLESPACE T0; ALTER TABLE DOCA ENABLE ROW MOVEMENT;
CREATE UNIQUE INDEX XPKDOCA ON DOCA( DOCA_ID ASC, ROW_PURGE_DATE ASC)LOCALREVERSE TABLESPACE I0; ALTER TABLE DOCA ADD CONSTRAINT XPKDOCA PRIMARY KEY (DOCA_ID); CREATE INDEX XFKDOCA_DOCA_BKG_PAX_ID ON DOCA( DOCA_BKG_PAX_ID ASC)LOCALREVERSETABLESPACE I0;
I would like to know the difference between the performance of the unique and non-unique local indexes?.
How do i list all tables from dba_tab_columns which contains both column name='id' and 'date'. I don't want to list the tables contains either 'id' or 'date'
how should i populate table column heading in list items of forms? I've create lov to select the column, then i have 10 separate list items. once i select the table from lov then list item should get populated with selected table column.
I am trying to ultimately as the title says separate a user input list into one column of entries. I am doing this through Cognos not a normal SQL editor which is what makes this a little harder to do. So far I have gotten that in general I can use the
SELECT 'First Entry' Asset FROM Dual Union SELECT 'Second Entry' Asset FROM Dual Union SELECT 'Third Entry' Asset FROM Dual
and this will give me 3 entries of data in one column. More can be added as long as the last statement doesn't have the union on it. So, the next step it would seem is to have a for loop combined with an if then or case statement that would find the number of entries and loop until we reach the number of entries and give me either SELECT 'First Entry' Asset FROM Dual Union or SELECT 'First Entry' Asset FROM Dual if we are on the last entry. I don't know the lingo to do this though. I have tried to get this to work with a simple test like cat, dog, horse, cow, pig, etc but it's frustrating that I can't get it to work. I can do all the individual steps I just can't seem to get it to work together. I have all the functions I need, I just need to the syntext to do a for loop along with an if then or case statement where the outcome is a valid select statement.
