只是想知道是否有人可以提供帮助，我有两个用于更改表（添加额外字段）的 PLSQL 语句，它们如下：

-- Make GC_NAB field for Next Action By Dropdown

begin
if 'VARCHAR2' = 'NUMBER' and length('VARCHAR2')>0 and length('')>0 then
  execute immediate 'alter table "SERVICEMAIL6"."ETD_GUESTCARE" add(GC_NAB VARCHAR2(10, ))';
elsif ('VARCHAR2' = 'NUMBER' and length('VARCHAR2')>0 and length('')=0) or
  'VARCHAR2' = 'VARCHAR2' then
  execute immediate 'alter table "SERVICEMAIL6"."ETD_GUESTCARE" add(GC_NAB VARCHAR2(10))';
else
  execute immediate 'alter table "SERVICEMAIL6"."ETD_GUESTCARE" add(GC_NAB VARCHAR2)';
end if;
commit;
end;

-- Make GC_NABID field for Next Action By Dropdown

begin
if 'NUMBER' = 'NUMBER' and length('NUMBER')>0 and length('')>0 then
  execute immediate 'alter table "SERVICEMAIL6"."ETD_GUESTCARE" add(GC_NABID NUMBER(, ))';
elsif ('NUMBER' = 'NUMBER' and length('NUMBER')>0 and length('')=0) or
  'NUMBER' = 'VARCHAR2' then
  execute immediate 'alter table "SERVICEMAIL6"."ETD_GUESTCARE" add(GC_NABID NUMBER())';
else
  execute immediate 'alter table "SERVICEMAIL6"."ETD_GUESTCARE" add(GC_NABID NUMBER)';
end if;
commit;
end;

当我分别运行这两个查询时，没有问题。但是，当如上所示一起运行时，Oracle 在启动第二条语句时给了我一个错误：

Error report:
ORA-06550: line 15, column 1:
PLS-00103: Encountered the symbol "BEGIN" 
06550. 00000 -  "line %s, column %s:\n%s"
*Cause:    Usually a PL/SQL compilation error.
*Action:

我假设这意味着第一个语句没有正确终止......我应该在语句之间添加任何内容以使其正常工作吗？

Oracle 一次可以采用一条 SQL 语句或 PL/SQL 匿名块。（不像 SQL Server 一次只能处理一个批处理。）所以，你有几个选择。

  1. 将两个匿名块包装在另一个匿名块中：

    begin
  -- Make GC_NAB field for Next Action By Dropdown 
  begin 
  if 'VARCHAR2' = 'NUMBER' and length('VARCHAR2')>0 and length('')>0 then 
    execute immediate 'alter table "SERVICEMAIL6"."ETD_GUESTCARE" add(GC_NAB VARCHAR2(10, ))'; 
  elsif ('VARCHAR2' = 'NUMBER' and length('VARCHAR2')>0 and length('')=0) or 
    'VARCHAR2' = 'VARCHAR2' then 
    execute immediate 'alter table "SERVICEMAIL6"."ETD_GUESTCARE" add(GC_NAB VARCHAR2(10))'; 
  else 
    execute immediate 'alter table "SERVICEMAIL6"."ETD_GUESTCARE" add(GC_NAB VARCHAR2)'; 
  end if; 
  commit; 
  end; 
  -- Make GC_NABID field for Next Action By Dropdown 
  begin 
  if 'NUMBER' = 'NUMBER' and length('NUMBER')>0 and length('')>0 then 
    execute immediate 'alter table "SERVICEMAIL6"."ETD_GUESTCARE" add(GC_NABID NUMBER(, ))'; 
  elsif ('NUMBER' = 'NUMBER' and length('NUMBER')>0 and length('')=0) or 
    'NUMBER' = 'VARCHAR2' then 
    execute immediate 'alter table "SERVICEMAIL6"."ETD_GUESTCARE" add(GC_NABID NUMBER())'; 
  else 
    execute immediate 'alter table "SERVICEMAIL6"."ETD_GUESTCARE" add(GC_NABID NUMBER)'; 
  end if; 
  commit; 
  end;
end;

  2. 告诉您用于将 PL/SQL 提交给 Oracle 的工具分别发送这两个块。如何做到这一点将是特定于工具的。在 SQL*PLUS 中，单独/一行将完成此操作：

      -- Make GC_NAB field for Next Action By Dropdown 
  begin 
  if 'VARCHAR2' = 'NUMBER' and length('VARCHAR2')>0 and length('')>0 then 
    execute immediate 'alter table "SERVICEMAIL6"."ETD_GUESTCARE" add(GC_NAB VARCHAR2(10, ))'; 
  elsif ('VARCHAR2' = 'NUMBER' and length('VARCHAR2')>0 and length('')=0) or 
    'VARCHAR2' = 'VARCHAR2' then 
    execute immediate 'alter table "SERVICEMAIL6"."ETD_GUESTCARE" add(GC_NAB VARCHAR2(10))'; 
  else 
    execute immediate 'alter table "SERVICEMAIL6"."ETD_GUESTCARE" add(GC_NAB VARCHAR2)'; 
  end if; 
  commit; 
  end; 
  /
  -- Make GC_NABID field for Next Action By Dropdown 
  begin 
  if 'NUMBER' = 'NUMBER' and length('NUMBER')>0 and length('')>0 then 
    execute immediate 'alter table "SERVICEMAIL6"."ETD_GUESTCARE" add(GC_NABID NUMBER(, ))'; 
  elsif ('NUMBER' = 'NUMBER' and length('NUMBER')>0 and length('')=0) or 
    'NUMBER' = 'VARCHAR2' then 
    execute immediate 'alter table "SERVICEMAIL6"."ETD_GUESTCARE" add(GC_NABID NUMBER())'; 
  else 
    execute immediate 'alter table "SERVICEMAIL6"."ETD_GUESTCARE" add(GC_NABID NUMBER)'; 
  end if; 
  commit; 
  end;
  /

是的，您需要/在每个end;.

一种可以通过两种方式实现

1) 在 pl/sql 文件中分别运行这两个块。

2）在主块中，您可以以这种方式运行两个 sbu 块：

begin  // main block
      begin 
       .....   [pl/sql commands]
       ......
      end
      begin   
      .......  [pl/sql commands]
      .......
      end
end // main ends
