删除表数据并插入临时表

语句先判断要删除表的对象是否存在，如果存在则插入一条新数据，如果不存在则先创建一个删除表，再插入相应数据

表对象：TableName

删除表对象：TableName_deled

主键ID：pCol

其它列名：Fields

            if (!TableName.Contains("_deled"))
            {
                string tbname = TableName + "_deled";
                try
                {
                    string sql = "set identity_insert " + tbname + " on;";
                    sql += "insert into " + tbname + " (" + pCol + "," + Fields + ") select " + pCol + "," + Fields + " from " + TableName + " where " + pCol + " in (" + ids + ");";
                    sql += "set identity_insert " + tbname + " off;";
                    ExecuteSql(sql);
                }
                catch { ExecuteSql("select * into " + TableName + "_deled from " + TableName + " where " + pCol + " in (" + ids + ")"); }
            }
