How to compare dates which stored as String in Sqlite Database and fetch data...?
I am storing date in a format DD.MM.YY
I have tried <= but it is working. And I want to compare only Date and not Time. So I am passing value as dd.mm.yy
I have tried "Select SUM(tramount) as s From mytrans where accno = " + acno + " AND trdate <= Datetime( '"+date+"' )" this too,but it is not working.
I have a huge datareader from sql server to insert into a sqlite database. I'm using xamarin C#, my problem is that the datareader is very big and the foreach item in datareader is very slow.
I have 131 fields in this table and is not feasible to use the index, I mean that I know that if I use the index instead of the name of the field I got better speed, but this is not feasible because fields can change.
Is there a method to deal with the datareader as a whole and accelerate the inserts?
I am currently learning how to use database in Android. For one of my app, I need to stock 500 string values in order to read them. Actually to fill my database, I read a .txt file at the database creation with all the string values inside. For each lines of .txt (corresponding to a string value), I create a new data in the database. The thing is I know that accessing a file can be long it is not a very good thing if there are thousands of values. According to that, I have two questions :
Is it really usefull to create a database ? (because I can directly access the string values by reading the .txt)
Is there a better way to fill the database ? Or a way to create a database already filled before the activity creation ? (because currently, each time you close the activity you close the database and each time you reopen it, it recreate and refill the database.)

I'm trying to insert into a junction table in Android. I already set up a content provider and have been using an AsyncQueryHandler to perform a lot of my operations in classes that don't require loaders. However, I need to insert into a junction table, and I'm at a loss for how to handle querying the related tables in order to receive the _ID values to place into the junction tables via a content provider/queryhandler.
For example, from this post's answer: Automatically Create Insert Statements to Fill Junction Table in a Pre-Created DB
insert into Name_Category values(
(select _id from Categories where category='CAT1'),
(select _id from Names where name='NAME1'));
(Edit) Here is an additional example: Insert into a junction table in SQLite
INSERT INTO ListsAndPlayers (ListsAndPlayersID, ListID, PlayerID)
VALUES (42,
(SELECT ListID FROM Lists WHERE ListName = 'Los Angeles Dodgers'),
(SELECT PlayerID FROM Players WHERE PlayerName = 'Clayton Kershaw'));
I have a very similar need in my application, and couldn't find any documentation on handling this with AsyncQueryHandlers or ContentProviders/ContentValues. What would the equivalent of this be using one of those?
Does anyone have suggestions for how they have handled this?
Thanks!
I have a wireshark dump in .csv format that I want to analyze. I tried importing the CSV file as described here. These are the commands I ran from the command line-
sqlite> create table network(no,time,source,dest,proto,info);
sqlite> .separator ",";
sqlite> .import E:\\Pavan\\_DataScience\\MP1\\network_data1\\challenge_network\\TestNetworkData.csv network;
Error: no such table: network;
sqlite> .tables
network
sqlite>
The .table command clearly shows that the network table is indeed present. I am not getting why the import command fails.
PS: I am running the sqlite3 executable downloaded from the official site on Windows.
