I have a table with no primary key constraints with some roles containing null value/duplicates. I then decided to alter the table to add composite primary key constraints on four columns (a, b, c, and d). I did this by using the same script that was used to create the original table but this time adding the not null constraints.
I then took and export of the original table. I now want to import the data to the newly created table but I am now getting the error: ORA-01400: cannot insert NULL into (string).
I will like to perform the import without NULL. Is there a parameter in impdp that I can use? I tried DATA_OPTIONS=SKIP_CONSTRAINT_ERRORS but it didn't work.
Beside options using impdp is there a way to do an insert statement like this insert into table a (select * from table) excluding NULL;?
Basically, I need to load the data into the newly created table without NULL.
the above error while tryin to run my control file in sqlloader as i need to load the csv data into oracle...what sequence i need to write so that i do not face the above error.
I am facing a simple problem, but could not resolve as yet, i want to replace two string 'M/S' and ' " ' with null, i know this command SELECT REPLACE(' " M/S Private linker " ','M/S',NULL) FROM dual Which command i should use
I wanted to print 'null' when the column value is null. Actually, i am doing something like this
select empno||','||''''||ename||'''''||','||comm||','||sal from emp
It gives the following output for example 7369,'pointers',,200 If I use the above values to form a insert statement it throws an error. As 'comm' value is not there.
I wish to get something like 7369,'pointers','',200 or 7369,'pointers',null,200 from the above select query
note I dint copy paste the query exactly from my sql*plus session as I am away from my oracle machine
I'm looking for a way to insert strings larger than 40.000 characters in a CLOB-field without geting the "ORA-01461: can bind a LONG value only for insert into a LONG column".
Something like this:
insert into MyClobTable(ID,Data) values ('101','A string containing more than 40000 characters...')
The problem is that a Java-application concatinates the string from a MSSQL-DB so I don't store the string in my oracle-DB. As far as I'm aware this means I can't chop my string in pieces and use declare to put the pieces in variables, right?
Below is an example I found but I don't think I can apply it on my case, correct?
SQL> CREATE TABLE myClob 2 (id NUMBER PRIMARY KEY, 3 clob_data CLOB);
i try to insert Concatenation string to my table,i need that all traps that has 12 length will be insert the new trapnum like this:
for example: 26001005CC45 = 260001005CC0045 ....... 08060027RF05 = 080600027RF0005 ......... and so....
update trap set TrapNum = ( select trim(both from to_char(substr(TrapNum,1,4),'0000'))|| trim(both from to_char(substr(TrapNum,5,1),'00'))|| trim(both from to_char(substr(TrapNum,6,3),'000'))|| substr(TrapNum,9,2)|| trim(both from to_char(substr(TrapNum,11,2),'0000')) from Trap) where length(Trapnum)=12
i have three tables ot_cut_head,ot_cut_det and om_mc_master based on which fourth table ot_cut_opr and fifth table ot_cut_mc must get populated , Conditions are as follows
first one is based on job_no in ot_cut_head the selection criteria will be filtered,if the job number is like '%M' then type MISC will be chosen ,if job number is '%G' then GRAT TYPE will be picked from om_mc_master (Machine Master) and operations and machines based on this will be filtered.
Second all the cd_ps_desc will be taken from ot_cut_det and will be compared with om_mc_master to get their corresponding operation codes and machine codes , there can be 2 operations or 1 operation.
Finally if the match is found record will be inserted into ot_cut_opr and ot_cut_mc ,based on the criterias and what i want is the search criteria to be more flexible and if there are 2 operations 2 rows will be inserted and if one opeation is defined in om_mc_master ,then only one record will be inserted.
We have to make sure that if based on operation number stage will be populated ,if its first operation then stage will be 1 and if its second operation the stage will be 2.like previous operation also depends on them , the second operation will have the previous operation as first operation and so on.
CREATE TABLE om_mc_master ( mc_type VARCHAR2(12),mc_prof VARCHAR2(30),mc_prep_cd1 VARCHAR2(30),mc_mach_cd1 VARCHAR2 (30),mc_prep_cd2 VARCHAR2(30),mc_mach_cd2 VARCHAR2(30)); INSERT INTO OM_MC_MASTER VALUES ('MISC','TEE SCH','IR','HO','RE','HO'); insert into om_mc_master values('MISC','Vertical Brace','R','HM','I','HO'); insert into om_mc_master values('MISC','Pipe','IR','HO',NULL,NULL); INSERT INTO OM_MC_MASTER VALUES ('GRAT','PL','RE','HO',NULL,NULL); SQL> SELECT * FROM OM_MC_MASTER; [code]....
I am running a GROUP BY query on a few columns of enumerated data like:
select count(*), Condition, Size group by Condition, Size;
COUNT(*) CONDITION SIZE -------- ---------- -------- 3 MINT L 2 FAIR L 4 FAIR M 1 MINT S
Well, let's say I also have a timestamp field in the database. I cannot run a group by with that involved because the time is recorded to the milisec and is unique for every record. Instead, I want to include this in my group by function based on whether or not it is NULL.
For example:
COUNT(*) CONDITION SIZE SOLDDATE -------- ---------- -------- ---------- 3 MINT L ISNULL 2 FAIR L NOTNULL 2 FAIR M NOTNULL 2 FAIR M ISNULL 1 MINT S ISNULL
I want to implement a business rule such as we have for each id at most 1 dat null. So, I've created this unique index on test.
create unique index x_only_one_dat_cess_null on test(id, case when dat_cess is null then 'NULL' else to_char(dat_cess, 'dd/mm/yyyy') end);
insert into test values (1, sysdate); insert into test values (1, sysdate - 1); insert into test values (1, null); insert into test values (1, null); -- ----- insert into test values (2, sysdate); insert into test values (2, sysdate - 1); insert into test values (2, null);
The 4th insert will cause an error and this is what I wanted to implement. OK. Now the problem is that for non-null values of dat, we can't have data like this
because of the unique index (the 2nd and the 3rd row are equal). So just for learning purposes, how could we allow at most one null value of dat and allow duplicates for non-null values of dat.
SQL> Describe Stu_Table Name Null? Type ----------------------------------------- -------- ---------------------------- STU_ID VARCHAR2(2) STU_NAME VARCHAR2(10) STU_CLASS VARCHAR2(10)
now when i try to modify this Stu_id column to not null its give me error.
SQL>ALTER TABLE Stu_Table MODIFY Stu_Id int(3)not null; ALTER TABLE Stu_Table MODIFY Stu_Id int(3)not null * ERROR at line 1: ORA-01735: invalid ALTER TABLE option
and when i try to add new column with not null its also gives me error
SQL> ALTER TABLE Stu_Table add C1_TEMP integer NOT NULL; ALTER TABLE Stu_Table add C1_TEMP integer NOT NULL * ERROR at line 1: ORA-01758: table must be empty to add mandatory (NOT NULL) column
I have 8 columns. Some of them might be null.I want to display all 8 columns in my result. Not null columns will be first and null at the end.Here is a sample data :
I'm facing some problem even after using INSTR function in Oracle.The problem is I have written the logic in the PL/SQL block which appends all the values fetched in a loop on the basis of whether the string is present or not.
For ex:
The first value fetched from the select query first is ABCDEFG which gets appended to a variable The next value fetched is AB even this has to be appended to the variable since this exactly doesn't match with ABCDEFG. The next value fetched is BCDEF even this has to be appended to the variable since this exactly doesn't match with ABCDEFG. The third Value fetched is ABCDEFG this will not get appended presently according to the logic which is correct.
writing that piece of code to append the value fetched which doesn't exactly match with the existing string
how to insert data in oracle table without writing insert statement in oracle 9i or above. i am not going to write insert all, merge, sqlloder and import data.
Suppose that, I have two tables: emp, dept emp records the empid, emp_name, deptid dept records the deptid, dept_name
Here is a record, it's a president or some special position in company, so it's deptid is set to NULL. Here comes the question, how can I print all the emp_name with their deptartment name?
I know how to print all the emp_name with their department name if they have dept_id, but is that possible that I merge the record with dept_id NULL?
