我正在使用一个存储过程，它在第一次执行时运行而不会抱怨权限。存储过程只有一个 UID/PWD 设置（没有不同的 UID/PWD 集用于授予不同的权限级别）。单对提供对所有内容的许可。
我调用存储过程的代码是这样的：
DataTable dtPriceComplianceResults
SQLDBHelper.ExecuteSQLReturnDataTable(PriceComplianceConstsAndUtils.SUMMARY_STOREDPROC, CommandType.StoredProcedure,
new SqlParameter()
{
ParameterName = "@BegDate",
SqlDbType = SqlDbType.VarChar,
Value = _begDateStr
},
new SqlParameter()
{
ParameterName = "@EndDate",
SqlDbType = SqlDbType.VarChar,
Value = _endDateStr
},
new SqlParameter()
{
ParameterName = "@Member",
SqlDbType = SqlDbType.VarChar,
Value = _member
},
new SqlParameter()
{
ParameterName = "@Unit",
SqlDbType = SqlDbType.VarChar,
Value = _unit
});
public static DataTable ExecuteSQLReturnDataTable(string sql, CommandType cmdType, params SqlParameter[] parameters)
{
using (DataSet ds = new DataSet())
using (SqlConnection connStr = new SqlConnection(PriceComplianceConstsAndUtils.CPSConnStr))
using (SqlCommand cmd = new SqlCommand(sql, connStr))
{
cmd.CommandType = cmdType;
cmd.CommandTimeout = EXTENDED_TIMEOUT;
foreach (var item in parameters)
{
cmd.Parameters.Add(item);
}
try
{
cmd.Connection.Open();
new SqlDataAdapter(cmd).Fill(ds);
}
catch (SqlException sqlex)
{
for (int i = 0; i < sqlex.Errors.Count; i++)
{
var sqlexDetail = String.Format("From ExecuteSQLReturnDataTable(), SQL Exception #{0}{1}Source: {2}{1}Number: {3}{1}State: {4}{1}Class: {5}{1}Server: {6}{1}Message: {7}{1}Procedure: {8}{1}LineNumber: {9}",
i + 1, // Some users would get the fantods if they saw #0
Environment.NewLine,
sqlex.Errors[i].Source,
sqlex.Errors[i].Number,
sqlex.Errors[i].State,
sqlex.Errors[i].Class,
sqlex.Errors[i].Server,
sqlex.Errors[i].Message,
sqlex.Errors[i].Procedure,
sqlex.Errors[i].LineNumber);
MessageBox.Show(sqlexDetail);
}
}
catch (Exception ex)
{
String exDetail = String.Format(PriceComplianceConstsAndUtils.ExceptionFormatString, ex.Message, Environment.NewLine, ex.Source, ex.StackTrace);
MessageBox.Show(exDetail);
}
return ds.Tables[0];
}
}
这是存储过程的第一部分：

发生的非常奇怪（ISTM）的事情是昨天存储过程根本无法运行，告诉我要么被删除的表（全部被删除在存储过程中，依次列出）要么不存在，要么我做了没有他们的许可。它们都存在。所以权限似乎是个问题。
然而，今天早上，在没有更改代码或数据库的情况下，存储过程在第一次运行时没有抱怨权限问题（仅限第一次）。
但是，在第二次执行时，它抱怨我没有 zContractDBPBase 表的权限。我想我现在有权删除前四个，但没有这个......？！？
IOW，我得到的错误消息（在“查询完成并出现错误”之后）现在是：
消息 3701，级别 11，状态 5，过程 sp_zDBP_pella，第 80 行
无法删除表“zContractDBPBase”，因为它不存在或您没有权限。
...而以前它是相同的消息，但对于所有删除的表，而不仅仅是一个。
那么为什么权限是可变的呢？我刷新了表列表，仍然看到我显然没有权限的表（“zContractDBPBase”）；在 Visual Studio IDE 中的服务器资源管理器和 LINQPad 中刷新时都可以看到它。
我需要做什么（除了更改存储过程本身，这超出了我的职责和专业知识范围）才能让存储过程允许“我”删除表？
