问题 My goal is to connect to an Oracle 9i instance from my OS X machine. I've followed the setup instructions here and got through them with no errors (eventually).

问题 Using SQL Plus, you can run a script with the "@" operator from the command line, as in: c:\>sqlplus username/password@databasename @"c:\my_script.sql" But is it possible to just run a single command with a similar syntax, without a whole separate script file? As in: c:\>sqlplus username/password@databasename @execute some_procedure I am interested in this because I want to write a batch file that simply executes a command, without generating a bunch of two-line ".sql" files. 回答1: I'm able to

问题 I've been searching for a while now but can't seem to find answers so here goes... I've got a CSV file that I want to import into a table in Oracle (9i/10i). Later on I plan to use this table as a lookup for another use. This is actually a workaround I'm working on since the fact that querying using the IN clause with more that 1000 values is not possible. How is this done using SQLPLUS? Thanks for your time! :) 回答1: SQL Loader helps load csv files into tables: SQL*Loader If you want sqlplus

问题 This question already has answers here : When do I need to use a semicolon vs a slash in Oracle SQL? (6 answers) Closed 2 years ago . I have an SQL script in which I want to automate the creation of a table. However, when I exec it, it seems as though it's trying to create the table 3 times. The first time, it creates the table. The next 2 times, it complains it already exists by throwing an "ORA-00955: name is already used by an existing object" Here my sql script(@/vagrant/scripts/db_tables

问题 I have the following pl/sql block: BEGIN FOR I IN 1 .. 5 LOOP INSERT INTO TEST_TABLE VALUES('&slno',SYSDATE); END LOOP; END; When I executed the above block it is taking only one input. But it is supposed to take 5 input in total. What is missing in my code? Can any one help me please? 回答1: It is a substitution variable - an sql*plus feature - and it doesn't work this way. You have to call undefine &slno or accept slno ... to make it take another input, but these are also sqlplus, not pl/sql

问题 Here is my code that I created for each of the tables, not sure how to join the tables to calculated the gpa's?? CREATE TABLE Student(SSN NUMBER(4) NOT NULL, SName VARCHAR(20) NOT NULL, Major VARCHAR(4), 回答1: Because grade and SSN are in the grades table, you dont need to join and can get the average grade like this: This gives the average grade per student, ordered by the grade: SELECT AVG(g.Grade), g.SSN FROM Grade g group by g.SSN order by AVG(g.Grade) If you wanted average grade per
