I have a Identifier column with start and stop dates along with description .
Two dates are separated by '-'. But the position of that character(-) is not constant always. Depending on the instr function I am able to divide the start and stop dates. But I am getting the performance problem because of huge data
I think the same logic will be implemented by regular expression also . How to write the equivalent logic by using regular expressions

(
TRANS_ID NUMBER(10),
TRANS_IDENTIFIER VARCHAR2(250)
) ;
insert into REG_EXP_TEST
(TRANS_ID, TRANS_IDENTIFIER)

The code which I am working on consists of an incoming dynamic string which be in the form of binary digits. The max size of the string will be 12 digits. For example, the string can be '111011000001', '000000000000', '111111011111', etc.
I need to find the number of occurences of '111' in the incoming string. Say in the 1st example, result will be 1, in the 2nd example result will be 0, and in the third example, the result will be 3.
I have been trying to capture the string length and replacing the variables '111' to find the number of occurences, but it isn't giving me the result that I want. This is what I have tried
SQL> conn hr/hr
Connected.
SQL> show user
USER is "HR"
[Code]....
I searched the forum and found a similar topic, and following that guideline, I even tried dividing the string with the length of the pattern. It works in some scenarios (the first and second examples mentioned below), while it fails in some scenarios (third example mentioned below)
SQL> select (length('11101110111') - length(replace('11101110111','111','')))/length('111') as occurences from dual;
OCCURENCES
----------
3
SQL> select (length('110111110111') - length(replace('110111110111','111','')))/length('111') as occurences from dual;
OCCURENCES
----------

SQL> select (length('111111111111') - length(replace('111111111111','111','')))/length('111') as occurences from dual;

I have this error (and solution):
ORA-02085: database link string connects to string
Cause: a database link connected to a database with a different name. The connection is rejected.
Action: create a database link with the same name as the database it connects to, or set global_names=false.
Where should I set global_names=false ?
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

What i have is table with:
mission_id, mission_type_id, security_level and code_name.
What i have to do is get the 10 most recent missions and change their security level to the highest one in their mission_type_id but ONLY if code_name length is >7
So far I have this, the problem is that the oracle moans about the order and wants me to close the bracket before the order
sql
UPDATE missions m
SET m.security_level = (
SELECT max(m2.security_level)
FROM missions m2
WHERE m2.mission_type_id = m.mission_type_id
AND length(m2.code_name) > 7
)
WHERE m.mission_ID IN (
Select m3.mission_id
From missions m3
ORDER BY m3.mission_id desc)

Version : Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production
I have a source which is of datatype RAW(1). Basic requirement is to convert it into binary, and then lookup the value of the 4th and 6th bit. Is this possible using simple SQL ?
Eg.
DataBinary
----- -------
EF1110 1111
From this binary output, i need to find the value of 4th and 5th bit.
So if the 4th bit is 1, I need to perform some operations if 0 then some other.
Create table test_hex_to_bin (col1 raw(1));
INSERT into test_hex_to_bin values ('99');
INSERT into test_hex_to_bin values ('EF');
INSERT into test_hex_to_bin values ('AB');
Basically the output should read as
Bit_number Value

I am reading Section 4-8 (page 42/216) in the Oracle Database 2-day Developer Guide from here:
[Code]....
It reads:
Suppose that you want to select every employee whose last name has a double vowel(two adjacent occurrences of the same vowel).
Example 4.9 shows how you can do this.
The regular expression ([AEIOU]) represents any vowel. The metacharacter 1 represents the first (and in this case, only) regular expression. The third function parameter, 'i', specifies that the match is case-insensitive.
Example 4.9 Selecting All Employees Whose Last Names Have Double Vowels
SELECT FIRST_NAME, LAST_NAME
FROM EMPLOYEES
WHERE REGEXP_LIKE(LAST_NAME, '([AEIOU])1', 'i');
Result is similar to:
FIRST_NAME LAST_NAME

I have contents like below:
BREAD,BISCUIT
BREAD,MILK,BISCUIT
COKE,MILK
MILK,SUGAR
Now combination from each row will be like below (Just for understanding):
BREAD,BISCUIT --> [COMBINATION] {BISCUIT} {BREAD} {BISCUIT,BREAD}
BREAD,MILK,BISCUIT --> [COMBINATION] {BISCUIT} {BREAD} {MILK} {BISCUIT,BREAD} {BISCUIT,MILK} {BREAD,MILK} {BISCUIT,BREAD,MILK}
COKE,MILK --> [COMBINATION] {COKE} {MILK} {COKE,MILK}
MILK,SUGAR --> [COMBINATION] {MILK} {SUGAR} {MILK,SUGAR}
Now the ultimate aim is to find unique combinations (even if the same combination is present in different rows, we have to consider it as one combination), along with its frequency, result will be like below:
BISCUIT [occurence in 2 transactions and total 4 transactions] = 2/4 = .5
BREAD [occurence in 2 transactions and total 4 transactions] = 2/4 = .5
COKE [occurence in 1 transactions and total 4 transactions] = 2/4 = .25
MILK = 3/4 = .75
[Code]....
writing query to find unique combination like above? What I have tried is as below:
create table test (row_no number, col_no number, item varchar2(50))
/
insert into test values (1,1,'BREAD');
insert into test values (1,2,'BISCUIT');
insert into test values (2,1,'BREAD');
[Code]....
But I am not able to form the exact query. let me know if this can't be done through a single query.
