PL/SQL :: Finding Length Of CLOB Column
Jul 11, 2012I had a varchar2 variable which was storing some data and I could use the LENGTH function to get the length of the data. However, If I change it to CLOB. What is the best way to get the length?
v_clob_size:= (DBMS_LOB.getlength(v_clob)) / 1024 / 1024;
DBMS_OUTPUT.put_line('CLOB Size ' || v_clob_size);
another one is
LENGTHB(TO_CHAR(SUBSTR(<clob-column>,1,4000))) But this seems restricted to first 4000 characters only.

Finding 10 Most Recent Missions
Jun 23, 2008What 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)

SQL & PL/SQL :: Finding Value Of Bits From Hex Number?
Jan 12, 2012Version : 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
----------------
4 1

SQL & PL/SQL :: Finding Double Vowels
Dec 14, 2010I 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
-------------------- -------------------------
Harrison Bloom
Lex De Haan
Kevin Feeney
Ki Gee
Nancy Greenberg
Danielle Greene
Alexander Khoo
David Lee
8 rows selected.
I don't understand how [AEIOU])1 would find a double vowel(two adjacent occurrences of the same vowel).

View 21 Replies View RelatedForms :: Finding Data
Jan 26, 2010I have simple table:
code = CHAR(5) as primary key
name = VARCHAR2(bla blal ba)
There is one-block-form based on this table. Block's datasource type = table and datatarget type = pl/sql procedure
Table API, Module API - all generated, all valid and seems correct. Now.. I try to update "name" from form. As soon as I type in something in the field, I get message "Row no longer exists". When digging deeper it seems that problem raises from lock_prodecure:
DECLARE
bk_data CGC$CL_1_9_DKD.cgc$rec_tab;
BEGIN
PLSQL_TABLE.POPULATE_TABLE(bk_data, 'DKD', PLSQL_TABLE.LOCK_RECORDS);
CGC$CL_1_9_DKD.lck(bk_data);
END;
It seems, it has some problems on populating the "code" attribute in bk_data.
how to solve this problem without massive re-coding??.
SQL & PL/SQL :: Finding UNIQUE Combination
Oct 4, 2012I 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.
Finding Correlation Using Derived Columns?
May 13, 2007I want to use the aggregate CORR_S function which take two numerical columns and output the correlation between them. Assuming I have the table:
Employee(name, gender, salary) where I want to create two derived columns, how would I do it?
Like,
-------------------
SELECT CORR_S(
SELECT salary
FROM employees
WHERE salary < 10000,
SELECT salary
FROM employees
WHERE salary > 10000
) as correlation
FROM employees
---------------------
It will find the correlation between salary's less than $10,000 in one column and salary's more than $10,000 in another column. Of course, I get an error when running the query. It's no problem if I use CORR_S(salary, salary) but I want to use derived columns, is it possible? Or, will I need to create a new table view with two new columns CORR_S(lowSalary, highSalary)?
