问题 I want to select column names but I don't know the table structure ahead of time and it may change so I can't just hard code the select statement with column names. I also do NOT want to select every column. Is there and easy way to do this? My thoughts are it's some kind of combination of these two queries but my SQL is not that good. SHOW COLUMNS FROM table_name; SELECT * FROM table_name; I tried using a sub select but it didn't work. Nothing seems to happen, I don't get an error I just get

问题 I want to load EF metadata from database at runtime. Is that scenario possible? First get the data from database, then write it to .ssdl, .msl and .csdl files sounds ok. But how to tell EF to use what I've loaded? Do I need to compile it or something like that? 回答1: Yes, you can do that. New up a MetadataWorkspace using the constructor which takes these files.

问题 I'm trying to implement managed debugger looking at MDBG sample. Currently I'm stuck trying to get base class hierarchy methods using IMetaDataImport. EnumMethods, that I'm using, enumerates MethodDef tokens representing methods of the specified type . But I want to enumerate all the methods in class hierarchy.

问题 How can I, throughout a given file, using java, retrieve an user name and its permissions to that file? Windows and Linux. 回答1: Java 7, which will be coming out this year, will support this.

Both involve interfacing with native libraries. The first is to use Java Native Interface (JNI) to write C code that interfaces
