SQL & PL/SQL :: Display Date Ranges In One Column As Separate Date Periods (start And End Date) In Two?
Jun 1, 2010I'm trying to work out how to take a table like this:
IDDate
12502-Feb-07
12516-Mar-07
12523-May-07
12524-May-07
12525-May-07
33302-Jan-09
33303-Jan-09
33304-Jan-09
33317-Mar-09
And display the data like this:
IDPeriodPeriod StartPeriod End
125102-Feb-0702-Feb-07
125216-Mar-0716-Mar-07
125323-May-0725-May-07
333102-Jan-0904-Jan-09
333217-Mar-0917-Mar-09
As you can see, it's split the entries into date ranges. If there is a 'lone' date, the 'period start' and the 'period end' are the same date.

Jun 21, 2012How can we partition a table based on date if it does not have a date column.
Actually I have to compare two tables on daily basis and fetch few rows from those two tables and enter it to a third table.But both these tables does not have a date column.
I am confused if i need to alter those tables and add date column or if there is some way in which i can compare the data from the two tables for that particular day only and not the whole table data.

ORA-02270 / No Matching Unique Or Primary Key For Column-list
Jan 14, 2013I'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:
CREATE TABLE TABLE1(
IDTABLE1 NUMBER(5),
NAME VARCHAR2(30)
);
CREATE TABLE TABLE2(
[code]....
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)
Server Utilities :: ORA-02270 / No Matching Unique Or Primary Key For Column-list
Jul 6, 2010I 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
exp system/<passowrd> file=/u05/oradata/dump/user1_schema.dmp log=/u05/oradata/dump/user1_schema_exp.log owner=user1 rows=y constraints=y triggers=y indexes=y statistics=none recordlength=65535 compress=no consistent=n grants=y
then imported in in user2 schema as follows
imp system/<password> file=/u05/oradata/dump/user1_schema.dmp log=/u05/oradata/dump/user2_schema_imp.log fromuser=user1 touser=user2 rows=y constraints=y indexes=y statistics=none recordlength=65535 grants=y
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.
SQL & PL/SQL :: Converting Number Column To Date Column
Dec 25, 2012I have a partitioned table with ~50 million rows that was setup with a number(10) instead of a date column. All the data in the table is ALWATS in this format YYYYMMDD

When I use the exchange partition method the parition is able to move the data from "monthly" table to "mth" table.
desc t1.mth; ### my temorary table
Name Null? Type
----------------------------------------- -------- ----------------------------
SEQ_NUM NUMBER(10)
DAY_DK NUMBER(10)
Than when I try to alter my temp table "mth". I get an error table must be empty to change column types.
alter table n546830.mth modify (DAY_DK date);
Next I tried making my temporary table "mth" a date column. When I an the exchange partition command I get the following error:
alter table t1.monthly exchange partition DEC_2012
with table t1.mth without validation;
alter table n546830.monthly exchange partition DEC_2012 with table n546830.mth without validation
*
ERROR at line 1:
ORA-14097: column type or size mismatch in ALTER TABLE EXCHANGE PARTITION
Method I can use to convert a number(10) to date column and keep the information in a table. Note, I don't care about HH:MM:SS as I never had that information to begin with and would be happy to set that part of the date column to all zeroes "00:00:00"
All Columns Of A Table Are Part Of Primary Key Column Of That Table?
Feb 22, 2011if a table contains two columns and both are part of the primary key of that table (Kind of obvoius).
should i opt for a index organized tbale in this case ?Or should i opt for another running sequential colum which would serve as a primary key of this table and define the actual two columns of the system as unique keys.
there is a drawback if a most of the tables of a database contain composite primary keys?
SQL & PL/SQL :: Primary And Foreign Key On Same Column And Foreign Key Index
Aug 25, 2010Create table Car
(Car_cd VARCHAR2(5),
Car_Desc VARCHAR2(50)
);
alter table Car
add constraint Car_PK primary key (Car_CD);
INSERT INTO Car (Car_Cd, Car_Desc) VALUES ('CORLA','COROLLA');
Commit;
[code]....
The requirement necessitates a new table to map car to manufacturer. This mapping table may later be expanded to contain other attributes Engine, MPG, etc to hold details specific to a car.But this is in future.
Create Table Car_Mapping_Details
(Car_Cd VARCHAR2(5),
Manufacturer_Cd VARCHAR2(5));
--Primary Key Constraint
ALTER TABLE Car_Mapping_Details
ADD CONSTRAINT Car_Mapping_Details_pk PRIMARY KEY (Car_Cd );
--Not able to create this as Car_cd is already a PK in this table and therefore has Unique Index
ALTER TABLE Car_Mapping_Details ADD CONSTRAINT Car_Mapping_Details_fk1
FOREIGN KEY (Car_Cd)REFERENCES Car (Car_Cd);
[code]....
But in this case the Car_Mapping_Details.Car_cd is itself is a primary key and therefore has Unique index.Although I was able to create foreign key constraint on Car_mapping_details.car_cd column (which is also Primary Key), I was not able to create Foreign Key Index on this column. It gives me Quote:ORA-01408: such column list already indexed.In other words, not creating foreign index for foreign key column lead to table-level lock? Or will the Unique Index in that primary key column be sufficient to avoid table-level lock?

Aug 2, 2012Is the index suggested on the date column.
Here is the nature of the date column in my case:
1. The table populates with 1000's of records every day with date being always incremental (current date).
2. The search criteria from the weba application (ADF) is based on the date, user gives the range.
3. From ADF I am referring to it as sql.Timestamp when building the query.
Does Index suggested on the date column here and if so what type of index ?

Split Date Column Into 4 Month Periods
Feb 11, 2011I have a table having a code column A and a date column D1 which represents the days when the code was inserted. I can have more then 1 date for a code.
The idea is to create another column (an id) which will correspond to all the inserted days of a code for a period of 4 month. if, after 4 month of the first insert, another records appears, then another id will be generated for my code. If a code has the date included in one of the intervals existing already, then it will just receive the corresponding id.
Example:
id code date
id1 cd1 01/01/2010
id1 cd1 04/03/2010
id1 cd1 22/04/2010
id2 cd1 27/05/2010
id2 cd1 21/06/2010
If a cd1 appears now on 22/05/2010, then i have to give it id2.
