查看Oracle当前用户下的主键、索引、sequence创建语句

oracle查看当前用户下所有外键、主键、索引、sequence的创建语句

把一个服务器上得A用户下得主键、外键、索引都移到B用户下

方法可以通过pl/sql developer工具可以导出在导入

以下是 oracle查看当前用户下所有主键的创建语句可以直接贴到其他用户

SELECT --'ALTER TABLE '||A.TABLE_NAME||' ADD CONSTRAINT '||A.CONSTRAINT_NAME||' PRIMARY KEY ('||A.COLUMN_NAME||') USING INDEX TABLESPACE USERS PCTFREE 10 INITRANS 2 MAXTRANS 255 STORAGE(INITIAL 64K MINEXTENTS 1 MAXEXTENTS UNLIMITED);'

 'ALTER TABLE ' || A.TABLE_NAME || ' ADD CONSTRAINT ' || A.CONSTRAINT_NAME ||

 ' PRIMARY KEY (' || A.COLUMN_NAME || ');'

  FROM USER_CONS_COLUMNS A

  JOIN USER_CONSTRAINTS B

    ON A.CONSTRAINT_NAME = B.CONSTRAINT_NAME

   AND A.POSITION = 1

   AND B.CONSTRAINT_TYPE = 'P';

外键的创建语句

SELECT DISTINCT 'ALTER TABLE ' || CON1.QCSJ_C000000000400004 ||

                ' ADD CONSTRAINT ' || CON1.QCSJ_C000000000400002 ||

                ' FOREIGN KEY (' || CON1.COLUMN_NAME || ') REFERENCES ' ||

                CON2.TABLE_NAME || ' (' || CON2.COLUMN_NAME || ');'

  FROM (SELECT *

          FROM USER_CONS_COLUMNS A

          JOIN USER_CONSTRAINTS B

            ON A.CONSTRAINT_NAME = B.CONSTRAINT_NAME

           AND A.POSITION = 1

           AND B.CONSTRAINT_TYPE = 'R') CON1,

       (SELECT TABLE_NAME, COLUMN_NAME, CONSTRAINT_NAME

          FROM (SELECT A1.CONSTRAINT_NAME,

                       A1.TABLE_NAME,

                       A1.COLUMN_NAME,

                       B1.CONSTRAINT_TYPE,

                       B1.R_CONSTRAINT_NAME

                  FROM USER_CONS_COLUMNS A1

                  JOIN USER_CONSTRAINTS B1

                    ON A1.CONSTRAINT_NAME = B1.CONSTRAINT_NAME

                 WHERE A1.POSITION = 1

                   and a1.CONSTRAINT_NAME in

                       ((SELECT B1.R_CONSTRAINT_NAME

                          FROM USER_CONS_COLUMNS A1

                          JOIN USER_CONSTRAINTS B1

                            ON A1.CONSTRAINT_NAME = B1.CONSTRAINT_NAME

                         WHERE A1.POSITION = 1)))) CON2

 WHERE CON1.R_CONSTRAINT_NAME = CON2.CONSTRAINT_NAME;

普通索引的创建语句

SELECT 'CREATE INDEX ' || INDEX_NAME || ' ON SINOSOFT.' || TABLE_NAME || ' (' ||

       COLUMN_NAME || ');'

  FROM USER_IND_COLUMNS

 WHERE INDEX_NAME IN (SELECT INDEX_NAME

                        FROM USER_IND_COLUMNS UIC

                       WHERE NOT EXISTS

                       (SELECT 1

                                FROM USER_CONS_COLUMNS UCC

                               WHERE POSITION = 1

                                 AND UIC.INDEX_NAME = UCC.CONSTRAINT_NAME)

                       GROUP BY INDEX_NAME

                      HAVING COUNT(INDEX_NAME) = 1);
sequence的创建语句

SELECT 'CREATE SEQUENCE ' || SEQUENCE_NAME || ' MINVALUE ' || MIN_VALUE ||

       ' MAXVALUE ' || MAX_VALUE || ' START WITH ' || LAST_NUMBER ||

       ' INCREMENT BY ' || INCREMENT_BY ||(CASE

         WHEN CACHE_SIZE = 0 THEN

          ' NOCACHE'

         ELSE

          ' CACHE ' ||CACHE_SIZE

       END)||';'

  FROM USER_SEQUENCES;
