How SQLite on Android handles long stings?
- by Levara
Hi!
I'm wondering how Android's implementation of SQLite handles long Strings. Reading from online documentation on sqlite, it said that strings in sqlite are limited to 1 million characters. My strings are definitely smaller.
I'm creating a simple RSS application, and after parsing a html document, and extracting text, I'm having problem saving it to a database. I have 2 tables in database, feeds and articles. RSS feeds are correctly saved and retrieved from feeds table, but when saving to the articles table, logcat is saying that it cannot save extracted text to it's column. I don't know if other columns are making problems too, no mention of them in logcat.
I'm wondering, since text is from an article on web, are signs like (",',;) creating problems? Is Android automaticaly escaping them, or I have to do that. I'm using a technique for inserting similar to one in notepad tutorial:
public long insertArticle(long feedid, String title, String link, String description, String h1,
String h2, String h3, String p, String image, long date) {
ContentValues initialValues = new ContentValues();
initialValues.put(KEY_FEEDID, feedid);
initialValues.put(KEY_TITLE, title);
initialValues.put(KEY_LINK, link);
initialValues.put(KEY_DESCRIPTION, description );
initialValues.put(KEY_H1, h1 );
initialValues.put(KEY_H2, h2);
initialValues.put(KEY_H3, h3);
initialValues.put(KEY_P, p);
initialValues.put(KEY_IMAGE, image);
initialValues.put(KEY_DATE, date);
return mDb.insert(DATABASE_TABLE_ARTICLES,null, initialValues);
}
Column P is for extracted text, h1, h2 and h3 are for headers from a page. Logcat reports only column p to be the problem. The table is created with following statement:
private static final String DATABASE_CREATE_ARTICLES =
"create table articles( _id integer primary key autoincrement, feedid integer, title text, link text not null, description text," +
"h1 text, h2 text, h3 text, p text, image text, date integer);";
Thanks!
