我有一个需要转换为Oracle的SQL存储过程。我在语法方面遇到了一些麻烦。
我得到的当前错误是：
错误（75,1）：PLS-00103：当遇到以下情况之一时遇到符号“DROP”:(如果使用＆lt;＆lt，则返回选择更新时，如果循环mod为空pragma，则返回选择更新;继续关闭当前删除获取锁定插入打开回滚保存点设置sql执行提交forall合并管道清除
我认为我还有更多。有人能帮我弄清楚我做错了吗？
这就是我所拥有的：

IN_FEATURENAME IN NVARCHAR2

您几乎肯定不希望在Oracle过程中创建和删除表。 Oracle临时表与SQL Server临时表非常不同。在SQL Server中，临时表的定义是会话的本地定义（假设表名前缀为#）。 Oracle没有这种本地临时表的概念。 Oracle中的临时表是全局的 - 该定义对所有会话都是可见的，数据仅对本地会话可见。这意味着您可以在定义永久表的同时创建临时表 - 在程序之外 - 并且您不会在过程中删除它们。
像
这样的东西CREATE GLOBAL TEMPORARY TABLE t_name_match
( KBID int NOT NULL,
SYMBOLID int NOT NULL,
FEATURE_NAME varchar2(30) NULL
)
ON COMMIT DELETE ROWS;
CREATE GLOBAL TEMPORARY TABLE t_compat_match
( KBID int NOT NULL,
CHARID int NOT NULL,
SYMBOLID int NOT NULL
)
ON COMMIT DELETE ROWS;
create or replace PROCEDURE "PROCEDURE1"
(
IN_FEATURENAME IN NVARCHAR2
, OUT_O_RC OUT SYS_REFCURSOR
) AS
BEGIN
/******************************************************************************* ***
** Name matches
******************************************************************************** ***/
/*
** Load matches to Name Table
*/
INSERT INTO t_name_match (KBID, SYMBOLID, FEATURE_NAME)
SELECT KBID, SYMBOLID, FEATURENAME
from FEATURE_MASTER
where FEATURENAME like IN_FEATURENAME;
/******************************************************************************* ***
** Compatibility Statement matches
******************************************************************************** ***/
/*
** Load matches to Compatibility table
*/
INSERT INTO t_compat_match (KBID, CHARID, SYMBOLID)
SELECT KBID, CHARID, SYMBOLID
from FEATURE_COMPAT
where INSTR(IN_FEATURENAME, LINE) > 0;
INSERT INTO t_name_match (KBID, SYMBOLID, FEATURE_NAME)
SELECT cm.KBID, cm.SYMBOLID, NULL
from (SELECT DISTINCT KBID, SYMBOLID
from t_compat_match) cm
where NOT EXISTS (SELECT 'X'
from t_name_match nm
where nm.KBID = cm.KBID
and nm.SYMBOLID = cm.SYMBOLID);
UPDATE t_name_match
SET FEATURE_NAME = (SELECT FEATURENAME
from FEATURE_MASTER
where nm.FEATURE_NAME IS NULL
and fm.KBID = nm.KBID
and fm.SYMBOLID = nm.SYMBOLID);
OPEN OUT_O_RC FOR
/******************************************************************************* ***
** Return result set
******************************************************************************** ***/
SELECT DISTINCT m.MODELNAME, m.VERSION, m.PLANTID, m.FROMDATE, m.TODATE,
m.BUILD, m.KBID, nm.SYMBOLID, nm.FEATURE_NAME as FEATURENAME
FROM t_name_match nm,
KB_MASTER m
WHERE m.KBID = nm.KBID
AND m.MODELGROUP = 'F'
ORDER BY m.MODELNAME, m.VERSION;
END PROCEDURE1;
可能会奏效。您在评论块之前有OPEN OUT_O_RC FOR而后面有SELECT这一事实使得这段代码难以理解。我也没有寻找其他语法错误。
当然，在Oracle中，首先使用临时表非常罕见 - 在SQL Server中使用临时表执行直接端口并在Oracle中使用临时表将创建一些非惯用的Oracle代码可能效率低于预期。如果不同的SQL Server过程创建具有相同名称和不同列的临时表，则在系统中结束数百或数千个临时表也可能会很烦人。您可以更好地使用本地集合，或者仅仅通过不首先实现数据并直接查询基础永久表。这取决于您首先在SQL Server中使用临时表的原因。例如，请参阅alternatives to temporary tables上的此主题。

DROP是一个在PL / SQL代码中无效的DDL语句。
使用“execute immediate”
替换它execute immediate "DROP TABLE t_name_match"
