oracle9i

问题 This question already has answers here : Oracle SQL pivot query (2 answers) Closed 2 years ago . Please help me to the SQL Oracle 9i , convert columns to rows in group by ID.

From this list: Table: Employees ID | DATA 1 | DATA 2 | DATA 3 | DATA 4 | ---------------------------------------------------------- 1 | 0 | 1 | 3 | 2 | 2 | 1 | 0 | 3 | 0 | Result ID | SOURCE | DATA | --------------

问题 Is adding tablespaces to a database decrease the performance of an Oracle 9 database? We consider that the number of request remains constant. Thx, Eric 回答1: No, tablespaces allow you to logically separate objects, and adding more makes no difference - you have the same amount of data stored on the same amount of disk. How tables and indexes are organised across tablespaces can make a difference; particularly having indexes in different tablespaces to their tables, though that's really to do

问题 Is is possible to find out the datatype of a column of a cursor or variable within block without using system tables? While I understand that I can use the system tables to find out this information it would be a lot slower. Something like, declare my_column_data_type varchar2(30); begin my_column_data_type := all_tables.table_name%type; dbms_output.put_line(my_column_data_type); end; I can't find any way of doing it without resorting to dbms_sql , which would be overkill for my eventual
