两个带有开始和结束的 PLSQL 语句,单独运行良好但不能一起运行?
只是想知道是否有人可以帮助解决这个问题,我有两个用于更改表(添加额外字段)的 PLSQL 语句,它们如下:
Just wondering if anyone can help with this, I have two PLSQL statements for altering tables (adding extra fields) and they are as follows:
-- 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,如上图一起运行时,Oracle在启动第二条语句时报错:
When I run these two queries separately, there are no problems. However, when run together as shown above, Oracle gives me an error when it starts the second statement:
Error report:
ORA-06550: line 15, column 1:
PLS-00103: Encountered the symbol "BEGIN"
06550. 00000 - "line %s, column %s:
%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......是否应该在语句之间添加任何内容以使其正常工作?
I'm assuming that this means the first statement is not terminated properly... is there anything I should put in between the statements to make it work properly?
推荐答案
Oracle 一次可以处理一个 SQL 语句或 PL/SQL 匿名块.(与 SQL Server 一次只能处理一个批处理不同.)因此,您有几个选择.
Oracle can take one SQL statement or PL/SQL anonymous block at a time. (Unlike SQL Server that can except a batch at a time.) So, you have a couple of options.
将两个匿名块包裹在另一个匿名块中:
Wrap the two anonymous blocks within another anonymous block:
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;
告诉你使用的工具将PL/SQL提交给Oracle,分别发送这两个块.如何做到这一点将取决于工具.在 SQL*PLUS 中,一行中的 /
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;
