如果我在SQL Server中运行以下内容:

SELECT HASHBYTES('SHA2_512', 'THE CAT SAT ON THE MAT')

然后在C#中运行它

string test = WordFunctions.SHA512("THE CAT SAT ON THE MAT");

我得到了同样的价值,两者都很棒.但是,如果我在C#代码中传递一个字符串变量,那么这样:

string words = "THE CAT SAT ON THE MAT"

byte[] test
test = WordFunctions.SHA512(words);

然后我没有得到相同的价值？!

有任何想法吗？

SHA512函数如下所示:

public static byte[] SHA512(String plaintext)
{
   // convert the passPhrase string into a byte array
   ASCIIEncoding AE = new ASCIIEncoding();
   byte[] passBuff = AE.GetBytes(plaintext);

   SHA512Managed hashVal = new SHA512Managed();
   byte[] passHash = hashVal.ComputeHash(passBuff);

   return passHash;
}

我正在将一些存储过程从Sybase TSQL转换为Oracle PL/SQL,我已经遇到了一个我正在努力解决的问题!

以下代码将无法运行:

DECLARE

t INT := 0;
t_error EXCEPTION;
v_line VARCHAR2(100);

BEGIN

SELECT COUNT(*) INTO t FROM user_tables WHERE table_name = UPPER('tbl_BSUK_PriceIssue');

IF t = 1 THEN
  EXECUTE IMMEDIATE 'DROP TABLE tbl_BSUK_PriceIssue';
  t := 0;
  SELECT COUNT(*) INTO t FROM user_tables WHERE table_name = UPPER('tbl_BSUK_PriceIssue');
  IF t = 1 THEN
    RAISE t_error;
  END IF;
END IF;

EXCEPTION
  WHEN t_error THEN
  v_line := '<<< FAILED DROPPING table tbl_BSUK_PriceIssue >>>';
  dbms_output.put_line (v_line);
  WHEN OTHERS THEN
    v_line := '<<< Unknown Error …
