我想创建这样的表:

create table ttt
(
   col1 varchar2(2),
   col2 varchar2(2),
   col3 varchar2(2),
   col4 varchar2(2),
   col5 varchar2(2)
);

使用此过程,但它不起作用.你能救我吗？

declare
  str varchar2(200);
  i int;
begin
  for i in 1 .. 5 loop
  begin
    str:=’str’||i||”;
  end;
  end loop;
  execute immediate ‘create table t1 (“str” varchar2(2) )’;
end;
/

提前致谢.

所以我有一个简单的SQL脚本,它创建了一个简单的库在线目录的数据库模式:

DROP TABLE book_copies;
/
DROP TABLE books_authors_xref;
/
DROP TABLE authors;
/
DROP TABLE books;
/

CREATE TABLE books (
    isbn VARCHAR2(13) NOT NULL PRIMARY KEY,
    title VARCHAR2(200),
    summary VARCHAR2(2000),
    date_published DATE,
    page_count NUMBER
);
/

CREATE TABLE authors (
    name VARCHAR2(200) NOT NULL PRIMARY KEY
);
/

CREATE TABLE books_authors_xref (
    author_name VARCHAR2(200),
    book_isbn VARCHAR2(13),
    CONSTRAINT pk_books_authors_xref PRIMARY KEY (author_name, book_isbn),
    CONSTRAINT fk_books_authors_xref1 FOREIGN KEY (author_name) REFERENCES authors (name),
    CONSTRAINT fk_books_authors_xref2 FOREIGN KEY (book_isbn) REFERENCES books (isbn)
); …

我可以访问表,但是当我在Anonymous块中运行相同的查询时

我需要检查记录集中的任何列是否包含数据.

我必须检查10列的数据.如果没有数据则必须退出,否则继续下一步.

我有一个名称Shipment有列的表HAWB, MAWB.如何检查这两列是否具有空值？

任何人都可以分享如何使用类似于下面的内容或PL/SQL中的内容将粗体文本写入.dat文件？

UTL_FILE.PUT_LINE(FPOINTER,'i want this in bold');

我的DW中有一个TIME维度,我想添加一个阵营来填补今年的赛季.我想做这样的事情:

create or replace
PROCEDURE "PROC_UPDATE_SEASON" 

IS 
CURSOR curs IS   
SELECT * FROM indw.time FOR UPDATE;  
 cur_d NUMBER;   
 cur_m NUMBER;   
 start_d NUMBER;   
 start_m NUMBER;   
 end_d NUMBER;   
 end_m NUMBER;
 cur_Date DATE;     

 BEGIN 
 FOR cs IN curs 
 LOOP 
     cur_d := to_number(to_char(cs.time_DAY,'dd')); 
     cur_m := to_number(to_char(cs.time_DAY,'mm')); 
     cur_date:= cs.time_DAY; -- this is my date dd-mm-yyyy or dd/mm/yyyy


     if ((cur_date in format dd/mm is >= 21/12 and <=31/12) OR cur_date>=01/01 and <=20/03) 
     UPDATE time t set t.time_SEASON = 'Winter' WHERE CURRENT OF curs; 
     else if cur_date_in …

动态请求如下所示:

request := 'select * from ' || param_table_name || ' where ' || column_name_list;

然后我做:

open cur1 for request;

直接获取的记录的确切类型cur1直到运行时才会知道,因为它应该对应用此过程的任何表不施加任何限制.但是,我如何迭代查询返回的内容？

我有一个存储过程:

create or replace procedure AAAAAA(
ID in dbms_sql.number_table,
Name in dbms_sql.varchar2s
)
is
 tableName varchar2(30) := 'QWERT_';
Begin
Forall k in 1...ID.COUNT SAVE EXCEPTIONS
EXECUTE IMMEDIATE  'insert into ' || tableName || ID(k) ||   
' values (:1,:2)' using ID(k), NAME(k);
--EXCEPTION HANDLING CODE
End;

但是,在编译上面的代码时,我得到了

[错误] PLS-00801(9:5):PLS-00801:内部错误[ *文件pdw4.c的ASSERT,第607行; 未知的表达式Expr = 283.AAAAAA_ FFF _P__274784 [9,5]].在运行此过程之前已经创建了"tableName || ID(k)"表.

知道为什么我得到这个错误.请帮忙.

我已经在SQL中编写了这个函数,我无法弄清楚为什么,但它继续在异常部分返回错误.我检查了语法,记录了但我没有运气,有人请帮忙吗？

错误返回:

Error on line 83: PLS-00103: Found symbol "EXCEPTION" instead one of the following:
    begin case declare end exit for goto if loop mod null pragma raise return select update while with
