Question

结果出现异常。为什么 sqlcomm 试图找到 doTable 默认 table 字符串 'blTableName'？我不会将此名称发送到 sqlcomm 的任何地方，因此我需要查看 sqlcomm 执行的 SQL 查询。

它是将参数添加到数据库到 'TableName' table 但无论如何异常，不返回 1

string t_table_name = "TableName";

try
{
    BindingList<doTable> bl = new 
    daTable().getTable(CoreStatic.s_SqlServerConfigLocal, new doTable() { table_ = t_table_name, TablePK = p_doWcfTicketQueue.TablePK, TableBFK = 
    CoreStatic.s_CurrentBPK }, Enums.DynamicType.BindingList);

    foreach (doTable item_odoTable in bl)
    { 
        SqlConnection SqlConn = new SqlConnection(blabla);
        SqlCommand sqlcomm = new SqlCommand("TableUpdate", SqlConn);

        SqlConn.Open();

        sqlcomm.CommandType = CommandType.StoredProcedure;

        sqlcomm.Parameters.Add(new SqlParameter() 
        { ParameterName = "@table", SqlDbType = SqlDbType.NVarChar, Direction = ParameterDirection.Input, Value = t_table_name });
        sqlcomm.Parameters.Add(new SqlParameter() 
        { ParameterName = "@TablePK", SqlDbType = SqlDbType.UniqueIdentifier, Direction = ParameterDirection.Input, Value = item_odoTable.TablePK });
        //is that possible to see sqlcomm sql query? like" insert into TableName... bla bla "

        result = sqlcomm.ExecuteNonQuery();
}//try
catch (SqlException exc)
{
   //exc = invalid object name 'blTableName'
}

Answer 1

我在尝试修改我写错的地方的存储过程时发现了问题。但我仍然想看看 sqlcomm.ExecuteNonQuery 作为 SQL 查询发送的内容

insert into blTableName//wrong
insert into '+@table+'//right
