PL/SQL :: Regular Expression Matching All Given Words
Nov 8, 2012I'm trying to match all sentences that contain words starting with given search tokens at least once. For example: if the given search token words are one and two then only sentences like "one plus one is two" should match. And should not match sentences like "one plus three is four". I was able to come up with this but I need a AND condition which I'm unable to get it right.
select count(*) from dual where regexp_like('one plus one is two', '(^|s)one|three', 'i');
Currently this gives a count of 1. But needs to give a count of 0 when the regexp is fixed.
search words : one two
one is less than two -> match
two is greater than one -> match
onetwo is union of two numbers -> match
onetwo is union of 2 numbers -> not a match as 'two' is not at the beginning of a word
one is less than three -> not a match as two is not present.
SQL & PL/SQL :: Remove Special Chars Using Regular Expression
Apr 9, 2013Can we use regular expression to eliminate all characters other than -
A to Z
0 to 9
Special characters like - &,%,~,@,#,$,^,*,_,+,=,,/,<,>
Example
String - TEST@#_~````}{!!!12311HELLO
Expected result - TEST@#_~12311HELLO
how we can use regular expression to achieve this result.
SQL & PL/SQL :: Finding Date Value In Given String By Using Regular Expression
Jul 3, 2012I 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
create table REG_EXP_TEST
(
TRANS_ID NUMBER(10),
TRANS_IDENTIFIER VARCHAR2(250)
) ;
insert into REG_EXP_TEST
(TRANS_ID, TRANS_IDENTIFIER)

PL/SQL :: How To Perform A Pattern Check - Regular Expression
Oct 16, 2012Is there a way to perform a pattern check on a value ?
For example: 654321HD9
The pattern is 6 numbers, followed by 2 letters, followed by 1 number. The data type for the attribute is a string.
Examples of right or wrong
654321HD9 - correct value
654321HD - wrong value
654321111 - wrong value
HD1111111 - wong value
The pattern has to be as i mentioned above (6 number, 2 letters, 1 number) otherwise its wrong. My pattern does not cover all cases.
select REGEXP_SUBSTR('654321HD9', '[0-9]+[A-Za-z]+[0-9]+') from dual;

SQL & PL/SQL :: Regular Expression To Find Commits In All Oracle Source?
Oct 14, 2013I would like to write a select that would return all places in DB that are commiting transaction.
E.g. package for testing:
CREATE OR REPLACE PACKAGE test.TEST_COMMIT AS
PROCEDURE THE_ONLY_COMMIT_IN_DB ;
END TEST_COMMIT;--not a match
CREATE OR REPLACE PACKAGE BODY test.TEST_COMMIT AS
[code]....
The select should return 4 rows with --ok.
SELECT *
FROM ALL_SOURCE ASO
WHERE
REGEXP_LIKE(ASO.TEXT,'commit(s*);','i' )
AND name = 'TEST_COMMIT'

JDeveloper, Java & XML :: Regular Expression For Exact Word And Occurrence
Mar 15, 2012I need to search a specific pattern from a source code. In word, I need to check whether "getCode" has been called or not, for all the string inside double-quote("). Following are sample code lines -
1.->if(val==23){ month_desc = "a sample data"; }
2.->if(val==23){ month_desc = getCode("a sample data"); }
3.->if(val==23){ month_desc = "a " + getCode("sample data"); }
4.->if(val==23){ month_desc = getCode("sample data"); var2="sample data2";}
Now, expression should be such that it will return true during check for 1, 3 and 4, although, for 3 & 4 getCode has been called for part of the String.

View 2 Replies View RelatedReal Time Apply For Logical Standby
Nov 15, 2012Oracle 11.2.0.3.0
I have a primary database orcl and logical standby database orcl_std.
Real time apply is enabled. I have standby redologs in both primary and standby sides and I`ve started recovery with below command:
ALTER DATABASE START LOGICAL STANDBY APPLY IMMEDIATE;
When I create a new table in primary database, I am unable to see it on standby database (Although real time apply is enabled) However, when I switch log in primary, I can see the new table in standby database.
My question is, why realtime apply is not working in my scenerio ? I was expecting to see the new table immediately in standby database once it is created in primary database. Why am I supposed to wait for log switch in real time apply ?
Best Tool / Method - Move Data In Real Time?
Sep 22, 2010We have oracle 9i database named A with 2 schema A1 and A2.User enters data at A1 schema and the incremental data moved to A2 schema after some verfications performed by some scheduled job on A1 schema.
we want to move this incremental data to B1 schema of another oracle 9i database B at the real time when data gets entered to A2 schema of A oracle 9i database. We have access to A2 schema of A database and B1 schema of B database.way to do it or best practice to do this activity or if there is any third party tool or any available oracle utility to perform it?
Note: A2 schema of A database and B1 schema of B database has one to one mapping.We want to avoid using trigger on A2 schema, how data gets populated from A1 to A2 schema .

Dec 11, 2012With 11gr2, by default, on STARTUP, the standby database is open
-> in READ ONLY mode
-> with Intended State: APPLY-ON
so the ACTIVE DATAGUARD option is in use ....
is there a way to deactivate REAL TIME QUERY permanently, so whether on STARTUP or STARTUP MOUNT, the standby stay only mounted with Intended State: APPLY-ON
The only way i found is to do the following :
SQL> startup

then
SQL> startup mount
DGMGRL> edit database 'PHNXENT' set state='APPLY-ON';
Performance Tuning :: Real Time Speed Improvements And Auto-trace Results
Feb 4, 2011I've got a query running a select count (*) over a table. The default plan takes in the order of 15 minutes to return, a hinted plan to use a different index takes 3 minutes to return.
Unfortunately I cant get at the index stats and a few other areas which I suspect may be key here.When running autotrace against the two queries I see fairly different values as one would expect.
Query
select count (*) from fulfilmentitem bfi where created >= sysdate-30 AND bfi.status = 'FA' AND bfi.fulfilmentmethod = 'D'
Slow run
PLAN_TABLE_OUTPUT
-----------------------------------------------------------------------------------------------
----------------------------------------------------------------------------------------------
| Id | Operation | Name | Rows | Bytes | Cost (%CPU)|
----------------------------------------------------------------------------------------------
| 0 | SELECT STATEMENT | | 1 | 15 | 33119 (1)|
| 1 | SORT AGGREGATE | | 1 | 15 | |
|* 2 | TABLE ACCESS BY INDEX ROWID| FULFILMENTITEM | 12525 | 183K| 33119 (1)|
|* 3 | INDEX RANGE SCAN | IDX_FULFIL_METHODSTATUS | 250K| | 1786 (1)|
----------------------------------------------------------------------------------------------
[code]....
IDX_FULFIL_METHODSTATUS is across FULFILMENTMETHOD & STATUS in that order.
IDX_BFI_CREATED is on CREATED and is approx 70% of the size of the other index
The row counts estimated in the explain plan are out, the count(*) comes in at 32.8k rows.As you will have seen, the fast run shows a pretty significant consistent get increase compared to the slow run and a decent though not dramatic physical read drop.
My uncertainty is around if these changes in consistent get/phys read values would typically be enough to suggest the real time improvements I'm observing or if other (albeit perhaps temporary) factors are involved. It is a prod OLTP environment so the data will be rapidly changing and that may be a factor.
I know it can never be an exact science without intimately knowing the hardware/current loads etc but I also know that there's enough experience on these boards to have a loose handle on if the time shifts between queries are likely (or not) to be reflective of the stat changes or if those differences alone shouldn't (or typically wouldn't account) for it.
I'm thinking about instructing the query to ignore its original plan but am hesitant to do so without being a little more confident that it's not just a timing thing or something other than the change of index approach which may be causing the improvement. the autotrace stat changes observed I couldn't put my hand on heart say "yup - that change is good, ignore the default index all the time for this job".
Replication :: Materialized View Flush Scenario
Mar 16, 2009Any solution for this scenario.
1)I have a master site and local site.
2)Materialized view is refreshed at local site... and the results are stored in a cache which Java uses .
3)Any request for the mview data is retrieved from cache.
4)Now I am refreshing matview again using fast refresh.. i.e only records that are changed in the master is updated at the local site.
5) I have to flush the cache .. while flushing i have to flush only those records that are changed.... coz full flush is not good and i have to re cache the entire data if i do full flush
My Question is How to identify the records that changed....so that I can only flush those records from cache. I want to identify the changed records.

Using PL/SQL Table With Regular Query
Apr 22, 2009How to use a table type variable with a regular query? For example, in my PL/SQL proc I have a table of employee names.
v_emp_tbl; --contains 'John','Sally','Ted'
Then I want to get names in a table called tbl_employees which are not in the pl/sql table. So if the table contains 'John','Sally','Ted',and 'Don' then I want to see 'Don'.
Not sure how to do this. Essentially I want something like:
Select emp_name into v_single_emp
from tbl_employees where emp_name NOT IN v_emp_tbl;
I know I can loop through the pl/sql table but I wanted to see if there is some other way.
