I have a table MYTABLE with a date column SDATE which is the primary key of the table and has a unique index on it. When I run this query: SELECT MIN(SDATE) FROM MYTABLE it gives answer instantly. The same happens for: SELECT MAX(SDATE) FROM MYTABLE But, if I query both together: SELECT MIN(SDATE), MAX(SDATE) FROM MYTABLE it takes much more time to execute. I analyzed the plans and found when one of min or max is queried, it uses INDEX FULL SCAN(MIN/MAX) but when both are queried at the same time, it does a FULL TABLE SCAN. why? Test Data: version 11g create table MYTABLE ( SDATE DATE not null

Since we have moved the database from 11.2.0.2.0 to 11.2.0.4.0 xmltype.transform function had got a specific behaviour. The problem is that before it did not work fine: it replaced all tags with open-close version (e.g. it did replace <br /> with <br></br> ), but I could live with it. Now it behaves the other way round (replaces everything with one tag) and it makes a big problem with <script></script> tag, because this tag must be explicitly closed with a </script> otherwise the browser thinks it is not closed, even if it is closed so <script /> => all web pages are corrupted now. Example:

I am new to cx_oracle. I have established a connection and I am able to create and drop a table using execute. Where I am failing is when I try to use "INSERT INTO ..." in execute. It doesn't show any error but it doesn't store any value either (I confirmed this by checking if the entry had taken place using sqlplus from shell). The code I used was: table_name = "T1" column = "D" insert_value = "test value" sqlcode = "INSERT INTO "+table_name+" ("+column+") VALUES ('"+insert_value+"')" cursor.execute(sqlcode) Please help me, any help would be appreciated. Thanks in advance. J Venu Murthy How

Possible Duplicate: LISTAGG in oracle to return distinct values I am using Oracle LISTAGG function but within my list of returned names I actually would like to eliminate duplicates and only return distinct values. The query I have is something like this: select a.id, a.change_id, LISTAGG(b.name, ',') WITHIN GROUP (ORDER BY b.name) AS "Product Name", from table_a a, table_b b where a.id = 1 and b.change_id = c.change_id group by a.id, a.change_id At the moment, it is returning (just showing one record): 1 1 NameA, NameA, NameB, NameC, NameD, Name D What I would like returned is: 1 1 NameA,
