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'm trying to import and export contact on an Android phone as vCards. Export works fine and i get the vCard string.

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?
View 4 Replies View RelatedI need to insert 1000 rows into SQLite DB. Each row has 12 columns, text and numbers, none is big. It takes literraly minutes to insert all 1000 items. I use SQLiteDatabase.insert to insert each row.
What can I do to improve this performance?
I'm trying to insert text into my SQLite database, but for some reason it doesn't work. It never executes..
Code below (this is my function that I'm calling):
public void setInfo(final String tableName, final int id, final String title, final String time, final String content) code...
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);
In Android is it possible to insert a sqlite timestamp into a database using ContentValues?
When I try to add it using something like
ContentValues args = new ContentValues();
args.put(MY_DATE,my_date);
I get an error telling me that my_date needs to be a string
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.
View 1 Replies View RelatedIn 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.
View 1 Replies View RelatedI 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.
The integers pass successfully but string is failed. What's the problem?

I have a query that pulls everything from a database into a list view.
code:..........
I want only the records where the field KEY_HOMEID matches a variable called journalId which should be a numeric string.
I would also like to know how to bring the variable into my DatabaseAdapter... would ((resource)this.getApplication()).getjournalId()) work? resource is a class that extends application.
I'm working on a android application that will display Strings to the user, and the user then has the option to add one to a favorite list. I have searched and searched and cannot find the proper way of doing this. I did get one open source project, everything worked until the user removed a favorite. The database would clear the row of data, but when a new row is added, it would behave as if the deleted row still had data, leaving blanks in the favorite list.
This is my insert method
public long insertString(String newString)
ContentValues newStringValue = new ContentValues();
newStringValue.put(KEY_STRING, newString);
return db.insert(DATABASE_TABLE, null, newStringValue);
The long returned will always increment even if i use the remove method:
public boolean removeString(long _rowIndex)
return db.delete(DATABASE_TABLE, KEY_ID + "=" + _rowIndex, null) > 0;
If I try to remove the third index, and the user removed a question at the third index, the method returns false, is there a way to completely remove all rows with no data?
I am trying to inject a long text entry into a SQLite database, in a TEXT field. This text has new lines in it (i.e. it spans multiple paragraphs). I can get the new lines to show up if I do the INSERT manually:
INSERT INTO "LOGENTRY" VALUES(5,40,'PLACE','line1
line2
line4
',1283990533315,'4A','TEXT','',NULL);
but if I have the equivalent text in a CSV file and attempt to .import it into the table, I get an error that it's expecting more columns than exist (as soon as the new line is encountered, the program assumes it's the end of the input and thus it's missing columns). Is this possible? Or is the only way to manually do each INSERT?
In Android if I have an edit text and the user entered 123456789012, how could I get the program to insert a dash every 4th character. ie: 1234-5678-9012? I guess you need to say something along the lines of:- a=Characters 1~4, b=Characters 5~8, c=Characters 9-12,

View 4 Replies View RelatedIn 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.

View 5 Replies View RelatedI have preferences where you can enable/disable what items will show up on the menu. There are 17 items. I made a string array in values/arrays.xml with titles for each of these 17 items.
I have preferences.xml which has the layout for my preferences file, and I would like to reference a single item from the string array to use as the title.
In the Android developer reference, I see how I can reference a single string with XML, but now how I can reference a string from an array resource in XML.
Can anybody give me some clue that how to convert binary string into a string(english). I have tried and googled so much but couldn't find an answer.
