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 don't understand how [AEIOU])1 would find a double vowel(two adjacent occurrences of the same vowel).
i'm trying to read a text file into an oracel table. I'm having issues with this statement FIELDS TERMINATED BY ' ' fields are separated by 2 spaces. How ever Oracle is not recognizing ' ' or " " as double space. It is treating as one space thus shifting all coulmns.
In the ideal world each subcategory of a single category would have unique sequence so if there are 3 subcategory for the same category then each of them would have 1,2,3 in sequence, if there are 5 subcategories then 1,2,3,4,5 for each of them etc.
Problem I'm facing is that some of the subcategories sequences for the same category has the same values . For instance for 4 subcategories of the same category, each of them has 1 (1,1,1,1) in a sequence.
So ideal world is :
Insert into Category values (123 ,'Category1'); Insert into Category values (234 ,'Category2'); Insert into Category values (345 ,'Category3'); Insert into Category values (456 ,'Category4'); Insert into Category values (567 ,'Category5'); Insert into Sub_Category values (1,123,1); Insert into Sub_Category values (2,123,2); Insert into Sub_Category values (3,123,3);
But I've also bad rows like this:
Insert into Sub_Category values (4,234,1); Insert into Sub_Category values (5,234,1); Insert into Sub_Category values (6,234,1); Insert into Sub_Category values (7,345,1); Insert into Sub_Category values (8,345,1); [code].....
Fix for this and my goal is to select all such cases where subcases have mixed up sequences as above and give them randomly numbers starting from 1. So if there are 3 subcategories like for CATEGORY 2 then just apply random number to the sequence of the subCATEGORIES like 1,2,3. For CATEGORY 3 : 1,2,3 to 7.
I was thinking to write two procedures one selecting all the categories and passing category ID to the other procedure that would actually update sequence, like this:
CREATE OR REPLACE PROCEDURE SCHEMA.SELECT_CATEGORY IS CURSOR c1 IS select category_ID from category where ...; BEGIN FOR a IN c1 LOOP UPDATE_SUBCATEGORY(a.Category_id); COMMIT; END LOOP; END; /
And the actual procedure updating subcategory:
CREATE OR REPLACE PROCEDURE SCHEMA.UPDATE_SUBCATEGORY BEGIN ............ END; /
write PROCEDURE SCHEMA.SELECT_CATEGORY cursor to not miss any of the categories ID having mixed up subcategory. There can be any of the doubled sequences like doubled 1 value (this is majority) but there can be any other doubles (or at least I need to make sure that there aren't any other doubles 2 values or 3 values in sequence etc.)
And how to write SCHEMA.UPDATE_SUBCATEGORY to loop through rows of subcategory and update sequence with values starting from 1 ?
I have oracle 10g database running on Sun Solaris. My database character set is AL32UTF8. Our user wants to store a double byte character and an image, I want to know what the column type should be using for these.
I am loading .csv file into Oracle using sql loader file has strings, and numberics, Strings are surrounded by double quotes(") and field terminated by comma(,)
load data BADFILE '/var/opt/app/bad/filename' DISCARDFILE '/var/opt/app/discard/filename' append into table source_file FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '"' TRAILING NULLCOLS
Some time String fields may have double quotes in it, at that time it is rejecting the records. how to handle those records to load into table.
Any way to replace the Double Quotes used to enclose column names with an alternative character. This is the SQL I have now that Works!
select (case when CUST is null then "/BIC/Z_SUPPLNT" else NM1 end) CMPNTSUPSRCE from TBL1, TBL2 where "/BIC/Z_MAJVEND"=CUST(+) and Material = '1ABCD456' order by Material
But would like to do something along these lines below but keep getting error "ORA-00936: missing expression".
select (case when CUST is null then chr(34)||/BIC/Z_SUPPLNT||chr(34) else NM1 end) CMPNTSUPSRCE from TBL1, TBL2 where chr(34)||/BIC/Z_MAJVEND||chr(34)=CUST(+) and Material = '1ABCD456' order by Material
I am having a similar problem like above ONLY in UNIX box where my datafile is delimited by "|". The last field is ITM_CMNT declared as VARCHAR2(60) in Oracle. When I have exactly 60bytes in the last field it rejects the record saying actual 61 and max allowed is 60. If i reduce it to < 60bytes then it is stored as a value enclosed with double quotes. The enclosing double quote is on the next line.
"PROC,RAM,FLPY,HD,ACT MTX CLR DSP,D/PCMCIA,TRKBAL,LIT ION BA"
Expected: the one below is exactly 60bytes.
PROC,RAM,FLPY,HD,ACT MTX CLR DSP,D/PCMCIA,TRKBAL,LIT ION BAT LOAD DATA INFILE * INTO TABLE TMPTLI_LAWSON_ITM_MST TRUNCATE FIELDS TERMINATED BY "|" (ITM_NO, HAZ_MAT_CD, ITM_SHRT_DS, ITM_SON "TRIM(:ITM_SON)", ADDED_DT DATE "YYYY-MM-DD", AVL_CD , ITM_CST_AMT, ITM_SLL_AMT, EXCHG_PRC_AMT , ITM_UOM "TRIM(:ITM_UOM)", PCK_QTY INTEGER EXTERNAL, SPC_HNDL_CD "TRIM(:SPC_HNDL_CD)", EFF_DT DATE "YYYY-MM-DD", ITM_CMNT "TRIM(:ITM_CMNT)")
I'm not really sure why oracle is not finding my Foreing Key, I'm creating an easy set of table for a company and I'm declaring all Primary keys and foreing keys as necessary and this is my
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)
How can i come to know that which current alert log file is being used for database? Is their a command at database level to find out the current alert log file to which database is using ?
I have read and used the AWR script (mentioned in the page Finding unused index for finding unused customised (Z) indexes in our SAP system using oracle 10.2.0.2 as the SAP database.
But this returns no rows. Is there any precondition? I want to know how much / many times the indexes are used...We are smelling that lot of unused index are there in the database.
i have table with name, count, flag with dublicate records
example
with swayam name , counts are 3, 4 with ramana name, counts are 5,5 with reddy name, counts are 1,2,3
i want to update the flag
if count are same then update one of record (flag='A') and other should be flag='R' if count are different then update the max count (flag='A') and other should be reject remaing (flag='R'). use below quires
CREATE TABLE TEST_DUB ( NAME VARCHAR2(99), V_COUNT NUMBER, FLAG VARCHAR2(1));
Insert into TEST_DUB (NAME, V_COUNT) Values ('SWAYAM', 3); Insert into TEST_DUB (NAME, V_COUNT) Values

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');
