I have created an Object Type and this Type is mapped to a column datatype in a table.This Table has values inserted.
create or replace
type column_type as object (
col_name varchar2(30),
col_comment varchar2(4000)
);
[code]....
ORA-02303: cannot drop or replace a type with type or table dependents...how to resolve this issue without having to delete any column from the table?
I have to change the datatype of a column from CLOB to varchar2, without changing the order of the columns. The table has no data.
I could find any other way other than dropping the CLOB columns and then adding new columns with varchar2 datatype. But this changes the order of the columns in the table.
I am currently in the process of migrating our database from US7ASCII to AL32UTF8 using DMU.
I am stuck at a point where I have encrypted data that, when the conversion happens, will be destroyed. Oracle suggests to move the data which is currently stored in VARCHAR2 datatype, to a "character set safe way" like hex notation or base64 before converting.
Is it possible to change the datatype of a column in a table online, using DBMS_REDEFINITION?
If Yes, then which of the options will be used with DBMS_REDEFINITION package?
I need to modify the column type that already has data in it, i need it change varchar to number then The datas entered have $ and , (e.g $3,200). I need the $ and , removed with column type set to numbers.
When i currently do this i get the following error:
The TABLE operation was not successful for the following reason:
ORA-01439: column to be modified must be empty to change datatype
I've tried unloading the data and loading the data using the spreadsheet, cut and past and csv file but both give me more errors, so i just want that one column modified.
I would need to convert the column datatype from BLOB to CLOB. currently in the table, the BLOB column has the data. the requirement is to convert this column from BLOB to CLOB datatype.
How to convert from BLOB datatype to CLOB datatype ?
While practicing with Triggers, the following error was encountered. An Object Type and an object Table are created.
create or replace
type typPerson is object
(id number,
firstname varchar2(30),
lastname varchar2(30)
[code].........
I executed the below insert statement, and I got the following error.
SQL> insert into person_obj_tab values (10,'Object1','From Trigger');
insert into person_obj_tab values (10,'Object1','From Trigger')

SQL> insert into person_obj_tab values (10,'Object','Original');
1 row created.Question:
1) Trigger of version 1 did not report any error during compilation, but during DML execution, hangs for sometime and gives the above error.
2) Whether direct assignment of Objects of greater size is possible inside triggers built on object Tables?
3) Suppose an object contain multiple attributes (say more than 20), then how to assign them inside a trigger?
I have a problem with executing oracleCommand.ExecuteReader() method. Whatever I try it always returns null and it won't create OracleData reader object. I'm using ODAC 1120320_x64 for .net 4.0 and timesten112241.win64. Don't sure what to do. Debugger is showing strange thing in OracleConnection object : ConnectionState = Closed, but output of ttStatus shows connection to TimesTen data store and ExecuteNonQuery() command works just fine with or without (in or out) parameters. But when I try to execute some query with multile output such as select *, I can't get any result.
I also have a strange problem with connection.Open() When I execute Open() i throws AccessViolationException that can be handled with [Handle ProcessCorruptedStateExceptions] attribute, but connection is established after that and my application works fine until I try to instance OracleDataReader object.
Here is the code:
OracleCommand select = null;
OracleDataReader reader = null;
select = new OracleCommand(selectStmt, connection);
select.CommandType = CommandType.Text;
try
{
reader = select.ExecuteReader(); // this line throws NullReferenceException
if (reader.HasRows)
{
[code]....
Just to mention, I tried it with different queries (pl/sql, plane sql, stored procedure) and all of them works fine in SQL Developer, but not in app.
Is there any query to find the dependent object details for any object. Like if mview is built on a table, then i should be able to find the table name with out checking code of the mview. similar way for view and functions or procedures etc...
View 5 Replies View RelatedI have an Type-object typeObj1 that consists another Type-object typeObj2. this def has another Type-object typeObj3. how to access variable declared inside typeObj3. I have syntax below for each Type.
CREATE OR REPLACE TYPE typeObj1
AS OBJECT
(
SYSTEM_IDENTIFER VARCHAR2(50),
PROCESS_TYPE VARCHAR2(50),
abc typeObj2
)

/I have tried to access the type-object in where clause in following way
FROM TABLE(CAST(I_typeObj1 AS typeObj1)) ITTPRC,
......
Where
.......
AND (ADDKEY.ADDTN_INFO_KEY_TYP_NM IN (SELECT ADDTN_INFO_KEY_TYP_NM FROM TABLE(ITTPRC.abc)))

AND (ADTINF.ADDTN_RQST_TYP_VALUE IN (SELECT ADDTN_RQST_VALUE FROM TABLE( ITTPRC.def)) OR ITTPRC.def IS NULL )
In this way i am able to access the variable inside typeObj3. But problem is i am getting error "ORA-01427 single-row subquery returns more than one row" when i pass more that one typeObj2.
I passed the values like this in proc execution.
T_T_A_I_V := typeObj3('asdasd',NULL,NULL),
typeObj3('String654',NULL,NULL),
typeObj3('abcdef',NULL,NULL));
T_T_A_I_I := typeObj2('CampusCode',T_T_A_I_V),
typeObj2('PlanNumber',T_T_A_I_V);
What i have done is removed typeObj3 from typeObj2, variables defined in typeObj3 are added in typeObj2 then i got ride of above error. is it correct
i was using sql server there is time keyword but in oracle which keyword i should take instead of time keyword?
View 7 Replies View RelatedI created a table of Number(20,4) column. I inserted an amount value 999999999999999.5555 but this value is rounded off to 1000000000000000.0000 automatically in Oracle.

I know that you can solve this problem with a stored procedure or anonymous block.
on this query. I need to get a particular value from a column which is a BLOB datatype. Here is the sample
data ID TESTDATA1 Best Buy
00001234 12222 30 00 2
Lowes 00001234 12222 100 00 3
Walmart 00001234 12222 129 00 4

Toshiba 00001234 12222 21 00 6
abcdefghij 00001234 12222 49 00
Where '00001234' is the Invoice , '12222' is Netamount field and highlighted in red is the $ amount for that invoice.
The only data i need query to return 12222 (netamount)= $amount. I tried using substr select substr((TESTDATA),19,26)test from TABLEA; But this gives me the only the first row but not other amount which have different positions.
Here is the desired output
OutputID TESTDATA 1

12222 129 4 12222 5000 5

The below table and functions are examples, but issue is like this.
i have one issue while forming below sql , Application will form this query at run time wih required inputs
it is failing because the application will not support the clob datatype.
Table : T_E (similar to EMP table structure)
This table has data similar to emp but bulk data around 10k records.
Query formed
select empno,ename, get_employees(deptno)
from t_e;
This sql query this is failing when function return varchar2 string more than 4000 size.Because in sql query size should not exceed 4000 for varchar2 data type , function return size can be upto 20000
Function which
CREATE OR REPLACE FUNCTION get_employees (p_deptno in emp.deptno%TYPE)
RETURN varchar2
IS
l_text varchar2(32767) := NULL;
BEGIN
FOR cur_rec IN (SELECT ename FROM t_e WHERE deptno = p_deptno) LOOP
l_text := l_text || ',' || cur_rec.ename;
END LOOP;
RETURN LTRIM(l_text, ',');
END;
I can try this with clob but application doesn't support that..so i tried with using clob in above function , after that while returning to application i want to conver the clob to char and return the entire string
select empno,ename, to_char(substring(get_employees(deptno),1,4000)) -- first 4000 characters
, to_char(substring(get_employees(deptno),4000,8000)) -- next 4000 characters
from t_e;
But this is failing how to return the entire string in above sql

I have question related to LONG datatype. Actually from google and get to know that one table can have only one LONG datatype when i searched for reason . i got these resons:-
With 9i (I believe) and later versions, Oracle deprecates using the long datatype in favor of the lob (clob, nclob and blog) datatypes. It is only supported for backward compatibility.
Restriction:- It can not be used in create type as an attribute of the defined type.
It can not be used in where conditions.
There can be no indexes on long columns.
Regular Expression are not possible.
long can not be returned from a stored function.
SQL can not call functions that have an attribute of type long.
And even more restrictions.
So I want to know that is only reason because of that Oracle doesn't allow us to make two Column or is there any strong reason which make it more logical Like storing of data in Row blocks or some thing else.
