问题 using sql loader, I know I can reference a ksh variable in my ctl file. For example I can write LOAD DATA INFILE '$PATH_IN_KSH/my_file.dat' ... I would like to add a WHEN clause like this WHEN (125:125) = '$P_NUMBER' P_NUMBER would have the value of a column in a table that I would retrieve with a select query. Is it possible to do that ? retrieve a value from a column with a select and somehow put it in the ksh variable so the ctl file can see it. (something with sql plus?) Thank you 回答1: As

问题 I have a lot of data that I want to spool to a csv file. I need to set heading off so the heading will not repeat every page. However, I still need my produced file to contain headers. Is there a way to add a row of headers (not to the table itself) into the query that won't actually be considered a header when spooling? This is my code which works, it just doesn't contain headers when I set heading off . select a.col1 as name1, a.col2 as name2, b.col3 as name3 from tab1 a, tab2 b Thanks in

问题 I am new db. Lets say I have created a view with force. So how can I get know whether the view created is invalid or not? I mean are there any queries from which I can get to know the validity status of the view? Thanks. 回答1: You can use Oracle dictionary view user_objects : select object_name, status from user_objects where object_type = 'VIEW' and object_name = 'YOUR_VIEW'; If the table on which the view is based is altered for any reason, you may have to recompile the view. For example, if

问题 I exported a table in Oracle (which has Vietnamese text) from computer A with:: exp system/***** BUFFER=64000 FILE=/tmp/export.dmp TABLES=(USERS.AREA) GRANTS=N INDEXES=NO ROWS=Y Then I imported that dump file on computer B (Centos same as A) imp system/***** file="/tmp/export_table.dmp" But when I query in SQL*Plus I see question marks instead of Vietnamese characters: SELECT AREA_ID,AREA_NAME,COMMENTS FROM USERS.AREA WHERE ROWNUM<2; I tried setting NLS_LANG="American_Amarica.VN8VN3" on

问题 I have created a database as part of university assignment and I have hit a snag with the question in the title. More likely I am being asked to find out how many films each company has made. Which suggests to me a group by query. But I have no idea where to begin. It is only a two mark question but the syntax is not clicking in my head. My schema is: CREATE TABLE Movie (movieID CHAR(3) , title CHAR(36), year NUMBER, company CHAR(50), totalNoms NUMBER, awardsWon NUMBER, DVDPrice NUMBER(5,2),
