Example: I want to search 'Hello world' for the first instance of the letter 'o' starting from the end, backwards.As you can see, result for DBMS_LOB.instr is null when entered -1 for offset.
select DBMS_LOB.instr('Hello world','o',-1,1) lob_i, instr('Hello world','o',-1,1) std_i from dual;
I have a requirement where the user input values will be passed as comma separated string to backend, which is queried against the table using instr. But the index present on the table is not using the index , due to the instr function.How can I create a index in such a way that The instr function uses it.
The below query is going for full table scan due to this.
select * from test_idx where (INSTR (','||'E10000'||',', ',' || ccn || ',') <> 0 OR 'E10000' = 'DEFAULT') and mod='90396' and rpt_flag='O' and smp_identifier=2
how to recreate the above index so that these queries uses this index.
I have a script that is using the INSTR function to search through a block of data for a specific string (CALL). I am ONLY looking for that string set but unfortunately, there are other words within that block of text that have that string set within it (e.g. CALL_MY_PHONE). Is there any way to make the INSTR search DISTINCT? Below is the code that I am using:
This is used the where clause of the REF CURSOR SELECT query which send the data back to SSRS
ie., SELECT BU.* FROM BU_DETAIL BU WHERE INSTR(V_BU_LST,BU_ID) <> 0;
INSTR has a chance to fail in this scenario if the value send from the front end is 123456,3456,4577
here 123456 does not exist in table, but it will be true for INSTR and values 1234 from table will be send back to SSRS which is wrong. Earlier I was using a function to convert the comma separated values to multi-rows and treat it like a lookup table.
But the main table has around million records , and each row has to processed against each row of lookup table, which makes it slower. To avoid this I used INSTR which is faster but can give wrong results.
i would like to know how can i used the OR "|" with REGEXP_SUBSTR
SELECT REGEXP_SUBSTR('500.90 Oracle Parkway, 12-12-2000 78 Redwood Shores, CA','([0-9]{1,2})-([0-9]{1,2})-([0-9]{4})') "REGEXPR_SUBSTR" FROM DUAL;this two condition ([0-9]{1,2}) ([0-9]{1,2}) ([0-9]{4}) or this i did it like this

1) I would like to alter that code above and substr the back 68 characters only with the 12 spaces padded in front, and the trailing nulls to total 80 characters staying as is. How would I put the below substr into that piece of code above?
2) I also would like the take whatever else there is preceding the 69th character counting it from the back and calling the column ADJ_FIRST_LINE.
Desired Output2 (ADJ#1-2M1YE2 TYPE)
No leading or trailing nulls and This is not a fixed amount of characters. ===============================================================================================
Result would be:
ADJ_FIRST_LINE ----------------- ADJ#1-2M1YE2 TYPE ADJ_SECOND_LINE --------------- 20100524 20100624 1MO/0DY ===============================================================================================
Can we have substr(date) as column name. I am trying to create a query where in I need to achieve something like this select s.xyz Today,s.abcd "6 Months ago" || to_char(add_months(sysdate,-6),'Mon rrrr') ||')'from sales_tab s.
DECLARE var VARCHAR2(4000); BEGIN SELECT DBMS_LOB.SUBSTR(v_clob,4000,1) INTO var FROM test_clob; END; ** v_clob is a CLOB column in test_clob table.
I get the below error:
wrong number or types of arguments in call to 'SUBSTR'"SYS"."DBMS_LOB"."SUBSTR": invalid identifier...I have execute privileges to DBMS_LOB.SUBSTR function.
I would like to have a column heading as follows in double inverted comma. but sqlplus environment returns column heading length equal to output value.
SQL> select substr('The independence day', 5,12) "Example of substr function" 2 from dual;
Example of s ------------ independence
I know that default column heading length is 30 character long.
but my column heading is less than 30 character long (which is 26)
How can i have column heading as Example of substr function?
A single master schema where many developers are accessing. all share same password.
now i would like to trace all the changes made by each users. so i create a individual users for all and grant permission to access that schema.do i have a possibility of auditing the changes did by each user for that particular schema
We have an application with many separate databases (one per customer). Given they share the same business requirements (service hours, change mgmt etc), we're interested in potentially consolidating the separate DBs (which are relatively small) into separate schemas within a fewer no of databases to reduce the overhead.
Our issue is that the application is hard-coded to use a specific administrator and application connection user name. Changing this is unfortunately not an option.
Given this limitation, is there any possibility to map a generic user into a customer-specific schema based on the database service that they connect to? Each customer connects to different database services but may use the same user name. We considered using private synonyms but this seems to acheive the opposite (i.e. many different users could connect and map to a single users schema). One thing to point out is that where there is a single user name, it is acceptable for a single password to be used across the different customer DBs as they will be a single admin/user.
I would like to create a table in another schema(CBF) as already exist in my schema(TLC) without data but related indexes,synonyms and grants should be include.
How could I do this without using export import. I am using TOAD 9.0.1.
move the tables with data present in the user scott(full) to another schema named test. In my case scott is in user tablespace and for test schema i have created different tablespace named test_tbs.
A user is using an ad hoc tool similar to SQL Developer called PeopleSoft Application Designer.
He creates a connection to the db, then issues an alter session set current_schema = 'restricted_schema'. The connected user does not have direct privileges on the "restricted_schema" which they call SYSADM.
After changing the schema context in that manner he creates objects in SYSADM. A schema trigger is then fired and grants privileges on the new objects created in SYSADM. Doing the same in either SQL Plus or SQL Developer does not fire the schema trigger.
I think SQL Plus and SQL Dev are working as they should. Altering the session like that does not change your identity - just the schema context. But, when you examine v_$session, the connection with this other tool looks exactly the same as one from SQL Plus or SQL Dev when changing the schema context in the session.
Instead of trying to figure out what this other tool is doing, is there any way for that schema trigger to fire when using this process from one of our tools?
