问题 I'm trying to read the date fields of Firefox places.sqlite datedase using ADO.NET and PowerShell. Obviously these fields are in Unix time. I'm looking for a conversion to .Net datetime or string Edit: I want to bind the datarow to a WPF GridView. I need either a way to do the conversion within the SQL query or some way while binding the datarows to the grid. 回答1: Something like this should put you on the right path: [TimeZone]::CurrentTimeZone.ToLocalTime(([datetime]'1/1/1970').AddSeconds(

问题 This is a bit of a complex problem, at least for me. Here it goes: I'm working as a user on linux server and it's safe to assume that installing any package not already installed is simply impossible. Also I need to set up working Python 2.5 (not installed) with working SQLite3 library (Sqlite in any form not installed). What I can do is: 1. Compile Python 2.5 and make it work 2. Compile amalgamation of SQLite3 Anyway - Python 2.5 is supposed to have interaction with Sqlite3 built-in

问题 This seems like it should be really easy to find out, but I don't see it documented anywhere. If I open a sqlite connection and begin a transaction without specifying a timeout by calling sqlite3_busy_timeout , what default value is used? Or will this somehow cause undefined behavior? The documentation of this method doesn't say. My specific use case is the version bundled with iOS, but I'm guessing the answer is pretty much the same across platforms. 回答1: If neither sqlite3_busy_timeout()

问题 So I see this question has a good answer, but I want to round up no matter what, instead of rounding down no matter what. Adding 1 to it before casting int wouldn't work because it would "round" 5.0 into 6.0, for example. So how should I implement ceil in SQLite? 回答1: How about this? select (case when x = cast(x as int) then cast(x as int) else 1 + cast(x as int) end) 回答2: This will give you the same answer more elegantly: SELECT CAST(x+1-1e-n AS INT); (assuming you won't have a precision

问题 I am trying to input 1000's of rows on SQLite3 with insert however the time it takes to insert is way too long. I've heard speed is greatly increased if the inserts are combined into one transactions. However, i cannot seem to get SQlite3 to skip checking that the file is written on the hard disk. this is a sample: if repeat != 'y': c.execute('INSERT INTO Hand (number, word) VALUES (null, ?)', [wordin[wordnum]]) print wordin[wordnum] data.commit() This is what i have at the begining. data =
