问题 I encountered this question in an interview and had no clue how to answer: There is a table which has a index on a column, and you query: select * from table_name where column_having_index="some value"; The query takes too long, and you find out that the index is not being used. If you think the performance of the query will be better using the index, how could you force the query to use the index? 回答1: You can use optimizer hints select /*+ INDEX(table_name index_name) */ from table etc...

The lines that were pasted in were of the type: @\\server\dir\dir\dir\commandfile1.txt; COMMIT; ...etc. It didn't like it when I tried that in a SQL window.

how to loop accepting user input with pl/sql?

I want to be able to insert a variable number of rows into a table based on user input? eg.

Thanks Tony Andrews As others have said, PL/SQL alone is not suitable for this task, you need a UI on top to interact with the end user. However, if you
