SQL Server 调用Oracle的存储过程收藏
原文如下：
通过SQL Linked Server 执行Oracle 存储过程小结
1 举例
我们可以通过下面的方法在SQL Server中通过Linked Server 来执行Oracle 存储过程。
(1) Oracle Package
PACKAGE Test_PACKAGE AS
TYPE t_t is TABLE of VARCHAR2(30)
INDEX BY BINARY_INTEGER;
PROCEDURE Test_procedure1
( p_BATCH_ID IN VARCHAR2,
p_Number IN number,
p_MSG OUT t_t,
p_MSG1 OUT t_t
);
END Test_PACKAGE;
PACKAGE BODY Test_PACKAGE AS
PROCEDURE Test_procedure1
( p_BATCH_ID IN VARCHAR2,
p_Number IN number,
p_MSG OUT t_t,
p_MSG1 OUT t_t
)
AS
BEGIN
p_MSG(1):='c';
p_MSG(2):='b';
p_MSG(3):='a';
p_MSG1(1):='abc';
RETURN;
COMMIT;
EXCEPTION
WHEN OTHERS THEN
ROLLBACK;
END Test_procedure1;
END Test_PACKAGE;
(2) 在SQL Server中通过Linked Server 来执行Oracle 存储过程
declare @BatchID nvarchar (40)
declare @QueryStr nvarchar (1024)
declare @StatusCode nvarchar(100)
declare @sql nvarchar(1024)
set @BatchID='AAA'
SET @QueryStr='{CALL GSN. Test_PACKAGE.Test_procedure1('''''+@BatchID +''''',''''4'''',{resultset 3, p_MSG},{resultset 1, p_MSG1})}'
(3)执行结果
(a)
select @sql='SELECT @StatusCode=p_msg FROM OPENQUERY (HI4DB_MS,'' '+@QueryStr+''')'
exec sp_executesql @sql,N'@StatusCode nvarchar(100) output',@StatusCod e output
print @StatusCode
答案:@StatusCode=’a’
(b)
select @sql='SELECT top 3 @StatusCode=p_msg FROM OPENQUERY (HI4DB
_MS,'''+@QueryStr+''')'
exec sp_executesql @sql,N'@StatusCode nvarchar(100) output',@StatusCod e output
print @StatusCode
答案:@StatusCode=’a’
(c)
select @sql='SELECT top 2 @StatusCode=p_msg FROM OPENQUERY (HI4DB _MS,'''+@QueryStr+''')'
exec sp_executesql @sql,N'@StatusCode nvarchar(100) output',@StatusCod e output
print @StatusCode
答案:@StatusCode=’b’
(d)
select @sql='SELECT top 1 @StatusCode=p_msg FROM OPENQUERY (HI4DB _MS,'''+@QueryStr+''')'
exec sp_executesql @sql,N'@StatusCode nvarchar(100) output',@StatusCod e output
print @StatusCode
答案:@StatusCode=’c’
(e)
SET @QueryStr='{CALL GSN. Test_PACKAGE.Test_procedure1('''''+@BatchID +''''',''''4'''',{resultset 1, p_MSG1},{resultset 3, p_MSG})}'----(注意这里p_MS G1和p_MSG交换次序了)
EXEC('SELECT p_msg1 FROM OPENQUERY (HI4DB_MS,'''+@QueryStr+''')') select @sql='SELECT @StatusCode=p_msg1 FROM OPENQUERY (HI4DB_MS, '''+@QueryStr+''')'
exec sp_executesql @sql,N'@StatusCode nvarchar(100) output',@StatusCod
