在 Apex Oracle 上制作 SQL 表时遇到问题

Question

I'm making two tables, STUDENT and STUDENTREPORT . I made STUDENT , but not the other. I ran the code, but it says missing or invalid option.

My STUDENTREPORT command:

Answer 1

Both commands are correctly written, they execute OK in eg SQL*Plus or SQL Developer:

SQL> CREATE TABLE studentreport (
  2      sr_number      VARCHAR2(5),
  3      sr_rade        VARCHAR2(5),
  4      sr_semester    VARCHAR2(5),
  5      class_attended NUMBER,
  6      s_id           VARCHAR2(5),
  7      PRIMARY KEY ( sr_number )
  8          USING INDEX enable
  9  );

Table created.

SQL> ALTER TABLE studentreport
  2      ADD FOREIGN KEY ( s_id )
  3          REFERENCES student ( s_id )
  4      ENABLE;

Table altered.

SQL>

But, in Oracle Apex' SQL Workshop , you can execute only one command at a time. Therefore:

• remove alter table (delete it from the editor) so that you'd first execute create table ; then delete that statement and execute alter table , or
• select (with a mouse, so that text turns blue ) create table and hit RUN to execute it; then select alter table and execute it with RUN

That's just how SQL Workshop behaves, there's nothing you can do about it (at least, I don't know what you could/should do, apart from what I already said).
