问题 I'm an Oracle 10g user. I had to write some SQL queries, and spotted a mysterious (as I see it) behaviour. Let's pretend we have a table, which is able to join itself in some kind of simple two-level tree structure. The next query gives me "ambiguity error", which is expected: select title from table1 left join table1 on condition BUT if I would add one more table to the join, the ambiguity problem will simply go away: select title from table1 join table2 on other_condition left join table1

问题 I would love to be able to use the system tables (Oracle in this case) to drive which fields are used in a SELECT statement. Something like: SELECT ( select column_name from all_tab_cols where table_Name='CLARITY_SER' AND OWNER='CLARITY' AND data_type='DATE' ) FROM CLARITY_SER This syntax doesn't work, as the subquery returns multiple rows, instead of one row with multiple columns. Is it possible to generate a SQL statement dynamically by querying the table schema information in order to

问题 I have a table student(id, name, department, age, score). I want to find the youngest student who has the highest(among the youngest students) score of each department. In SQL Server, I can use following SQL. select * from student s1 where s1.id in (select s2.id from student s2 where s2.department = s1.department order by age asc, score desc top 1). However, in Oracle, you cannot use the order by clause in subquery and there is no limit/top like keyword. I have to join the student table with

问题 Is there any other way to get datetime field from oracle database in 24hour format???like -> "select getxsddate(col_name) from tab_name" will get you datetime format as "2012-04-04T12:31:00"...I wanted to know if there are any other ways as i`m not satisfied with this format. 回答1: select to_char(col_name, 'yyyy-mm-dd hh24:mi:ss') from tab_name You can read more about to_char function here 回答2: Another very simple way is to set, in the database nls parameters, the parameter date_format='DD-MM
