问题 I used the following command SELECT json_extract(data,'$.address') FROM data; and output as CSV file. Output in CSV file is enter image description here Field (column) in CSV file is saved as 2 lines for 1 field (column). Eg- "71 CHOA CHU KANG LOOP NORTHVALE" How could I save field(column) as 1 line ? That is I don't want to include new line character in filed(column).

问题 I'm developing a game where there are 4 buildings and in these buildings, there are 3 stages inside. The player can play the stages one by one, from one building to another, however, when they have finished one cycle (eg. going from building 1 stage 1 to building 4 stage 3) I keep getting this error where it's an error 14 (SQLITE_CANTOPEN) whenever the player clicks on another building. It keeps happening every single time I test the app. Can anyone help me? :S edit: sorry, here's the code I

问题 With MSSQL, I can mix in case, if...then, and while constructs in my SQL code. Is anything similar available for SQLite? I have not seen anything on "mixing procedurally" with SQLite, anywhere.

问题 I am trying to write a custom report in Spiceworks, which uses SQLite queries. This report will fetch me hard drive serial numbers that are unfortunately stored in a few different ways depending on what version of Windows and WMI were on the machine. Three common examples (which are enough to get to the actual question) are as follows: Actual serial number: 5VG95AZF Hexadecimal string with leading spaces: 2020202057202d44585730354341543934383433 Hexadecimal string with leading zeroes:

问题 I have a simple GET route setup with Koa and sql3lite that fetches from a json file some data, with the use of a wrapper. A helper sql3lite wrapper exposes an initialize function for the main server index.js file to load into memory on startup: index.js const data = require('./data'); data.initialize(); const server = createServer(); server.listen(PORT, () => { console.log(`server listening on port ${PORT}`); }); The data.js file serves as a wrapper around the sqlite3 node library, so routes

问题 Can anyone please give me a simpler solution for this? I'm trying to query four different tables in my database and iterating them with a very bizarre FOR pattern, within HTML. All the time I get MemoryError because the database is huge. Python script: import sqlite3 con=sqlite3.connect('/home/sergiuster/Downloads/python/exportSQL.db', check_same_thread=False) con.row_factory = sqlite3.Row #QUERY MATERIALECARACT cur = con.cursor() cur.execute("SELECT MaterialeCaracteristici.CodProdus,

问题 I created an SQlite database to store on it all latitudes and longitudes to display them in map. For the add of the values i didn't encouter any problem, i used this code: CoordBD CoordBd = new CoordBD(this); Coordo coordo = new Coordo(36.869686,10.315642 ); CoordBd.open(); CoordBd.insertCoordo(coordo); But i don't know how to insert them one by one in map, i usually/manually make this: GeoPoint point2 = new GeoPoint(microdegrees(36.86774),microdegrees(10.305302)); pinOverlay.addPoint(point2)
