Oracle JDBC 드라이버 받기...

1.먼저 자신의 DB의 버전 알아보기(해당테이블 조회권한 있는 유저로 조회, DBA)

select *
from v$version ;

2.자신의 PC나 서버에 설치된 java 버전 알아보기

java -version

3.아래에서 해당 JDBC 드라이버 받기(오라클버전과 JDK버전에 맞게, 없으면 상위로 받으면 됨...)

다운로드 후 이름을 ojdbc14.jar로 변경하세요.

create table tt_test(
aa number,
bb number(15),
cc number(15,2)
);

insert into tt_test
values (15.63, 15.63, 15.63);

select *
--delete
from tt_test;

number 타입에 15.63 입력==> 15.63
number(15) 타입에 15.63 입력 ==> 16 <== 반올림 됨!
number(15,2)타입에 15.63 입력 ==> 15.63

number(15,2)타입에 15.6371 입력 ==> 15.64 반올림
number(15,2)타입에 12345678901234.64 ===> 오라클에러 ORA-01438

따라서 실수(소수점 포함)를 입력하려면
NUMBER타입이나 NUMBER(??,??) 로 정의해야 합니다.

select instance_name, startup_time, status
from v$instance;

오라클에서 테이블명 최대길이(30글자)입니다.

더 긴 경우는생성이 안됩니다.

참고하세요.

그리고 PK나 CONSTRAINT를 생성시도 동일하므로 참고하세요.

You can let Export prompt you for parameters by entering the EXP
command followed by your username/password:

Example: EXP SCOTT/TIGER

Or, you can control how Export runs by entering the EXP command followed
by various arguments. To specify parameters, you use keywords:

Format: EXP KEYWORD=value or KEYWORD=(value1,value2,...,valueN)
Example: EXP SCOTT/TIGER GRANTS=Y TABLES=(EMP,DEPT,MGR)
or TABLES=(T1:P1,T1:P2), if T1 is partitioned table

USERID must be the first parameter on the command line.

Keyword Description (Default) Keyword Description (Default)
--------------------------------------------------------------------------
USERID username/password FULL export entire file (N)
BUFFER size of data buffer OWNER list of owner usernames
FILE output files (EXPDAT.DMP) TABLES list of table names
COMPRESS import into one extent (Y) RECORDLENGTH length of IO record
GRANTS export grants (Y) INCTYPE incremental export type
INDEXES export indexes (Y) RECORD track incr. export (Y)
DIRECT direct path (N) TRIGGERS export triggers (Y)
LOG log file of screen output STATISTICS analyze objects (ESTIMATE)
ROWS export data rows (Y) PARFILE parameter filename
CONSISTENT cross-table consistency(N) CONSTRAINTS export constraints (Y)

OBJECT_CONSISTENT transaction set to read only during object export (N)
FEEDBACK display progress every x rows (0)
FILESIZE maximum size of each dump file
FLASHBACK_SCN SCN used to set session snapshot back to
FLASHBACK_TIME time used to get the SCN closest to the specified time
QUERY select clause used to export a subset of a table
RESUMABLE suspend when a space related error is encountered(N)
RESUMABLE_NAME text string used to identify resumable statement
RESUMABLE_TIMEOUT wait time for RESUMABLE
TTS_FULL_CHECK perform full or partial dependency check for TTS
VOLSIZE number of bytes to write to each tape volume
TABLESPACES list of tablespaces to export
TRANSPORT_TABLESPACE export transportable tablespace metadata (N)
TEMPLATE template name which invokes iAS mode export

Export terminated successfully without warnings.
