Android :: Insert SQLite Record With Datetime Set To 'now' In Droid App?
Apr 16, 2009
Say, we have a table created as:
create table notes (_id integer primary key autoincrement, created_date date)
To insert a record, I'd use
ContentValues initialValues = new ContentValues();
initialValues.put("date_created", "");
long rowId = mDb.insert(DATABASE_TABLE, null, initialValues);
But how to set the date_created column to "now"? To make it clear, the
initialValues.put("date_created", "datetime('now')");
Is not the right solution. It just sets the column to "datetime('now')" text.

I have array list of geopoints
List<GeoPoint> geoPointsArray = new ArrayList<GeoPoint>();
I want to put geoPointsArray array in to SQLite database and then fetch the data back as an array.
Now I use ContentValues for insert into array as:
ContentValues initialValues = new ContentValues();
initialValues.put(KEY_TIME, time);
db.insert(tableName, null, initialValues);

I'm trying to insert values on Android SQLite Database. The question is, Iḿ trying to insert a word, the table has 3 columns, ID, WORD, COUNT. When I insert a word in the database, some method will verify if this word exists on the database. If yes, it will increment the value of COUNT for this word.

I try to increase the value of an integer key in a row in my table. However, nothing really seems to happen.
db.rawQuery("UPDATE table SET key = key + 1 WHERE name=?", new String[] {name});
However, this code works fine (just sets the key to a hard-coded value):
ContentValues values = new ContentValues();
values.put("key", 2);
db.update("table", values, "name=?", new String[] {name});
Also tried '?' instead of just ?, but it resulted just in a run-time error.

I want to insert a String value call temp but I don't seems to get it working for the INSERT INTO statement. Anything wrong with the code? This is the initialization to create table and insert some default values into the table if the database doesn't exist. Code...

I have a database (stored on a Class 6 SD card) with a single empty table (5 columns). There is an index on each column. Performing a single INSERT statement (whether using an SQLiteStatement or calling SQLiteDatabase.insert()) takes about 800ms on my N1 (2.2.1). The INSERT statement does NOT do anything fancy (like subselects). Is there any way to speed this up?

In my project, I would like to create a database with single table. I would also like to insert data on this table from word or excel document. is it possible? if so please how can I do it? some code snippets would be of great help. I have four different activities which I would like them to interact with this single table. the first is the main activity and its purpose is just to launch the other three activities according to user choice. so it has no interaction with the DB. but the other three activities will read from the table whenever called. Can you please tell me how to call the dbhelper on these activities? I am unable to do this and I am currently creating one db per each activity which is not the optimal way.

I have a table called "images":
CODE:.........
On inserting a row, I'd like the URL column to be unique. At the same time, I'd like to find out the id of the row with that URL.
INSERT OR IGNORE images (url, caption) VALUES ("http://stackoverflow.com", "A logo"); SELECT last_insert_rowid(); -- returns the id iff there was an insert.
Of course, I'd like to do it as quickly as possible, though my first thought was along the the lines of the following pseudo code:
CODE:...........
But this seems hopelessly inefficient.
What is the most performant way of getting the Auto incremented row id from an INSERT OR IGNORE statement.

I need to introduce a menu option on clicking which the whole SQLite database file stored at "data/data/com.company.packName/databases/" gets deleted. Using DROP TABLE command would only delete the table under a particular database.
How can i achieve this?

I've a problem with a query in sqlite3.
The query is very simple:
SELECT MAX (INIT_DATE) INIT_DATE FROM TABLE;
When my application execute this query, and the table is empty, a record is returned. I can't understand why a record is being returned if the table is empty. It should return cero results.
I've tried to execute the query in two different ways:
cursor = db.query(true, "TABLE", new String[] {"MAX(INIT_DATE) AS INIT_DATE"}, null, null, null, null, null, null);
cursor = db.rawQuery("SELECT MAX(INIT_DATE) AS INIT_DATE FROM TABLE", null);

In Android, capturing date from datepicker and storing as string in sqlite. Sorting by date doesn't work because they're strings (unless I'm doing it wrong.I've googled this issue for ~5 days, and it looks like there should be a way to capture the date from the date picker, convert it to a Long, store it in sqlite as a Long, select and sort on the Long date value, then convert the Long back to a "mm/dd/yyyy" string for display. I've tried various combinations of parse statements, Date, FormatDate, etc. with no luck at all.On activity start, get today's date and display it in button which calls the datepicker.Capture new date from datepicker (if one is entered), save it as a long to sqlite.On opening an activity showing a listview of records, select from sqlite with orderby on date (Long), convert Long to "mm/dd/yyyy" string for display in ListView.

myInput.setText(myInput.getText().replace(myInput.getSelectionStart(), myInput.getSelectionEnd(), myText));
myInput.setSelection(myInput.getSelectionStart() + myText.length(), myInput.getSelectionEnd() + myText.length())
I ask because I think this code is much longer than it needs to be - Is there something shorter like myInput.insertTextAtCursor(myText) or is this the way everyone does it?

I just bought a used Droid in great shape last night. After I got it home, I noticed that the previous owner removed the micro SD card. No big deal as I have two 8GB ones, so I popped in one of them and went to the settings menu to mount it. Long story short is the Droid won't read either card even though I can read them from my PC just fine.I suspect this is actually a physical problem; when I insert the micro SD card the card itself goes over the black plastic piece in the slot, then continues to ride over the metal part visible through the retaining clip hole. After it is inserted I can see the card in the hole around the retaining clip for the card in the 1" wide metal piece that spans the middle of the phone. After a ton of googling I finally found a post on a different forum that says the card should go UNDER this metal part and not over, but on my phone there is no room for a micro SD card; it's pretty flush with the black plastic piece and some gentle prying isn't helping any.Can anyone verify where the micro SD card should sit?
