placing string into sqlite

Question

I've created a table in android. when i try to add or take any data it crashes .. what could be the problem ??

code on which crashes:

return db.query(DATABASE_TABLE, new String[] {KEY_ID, KEY_STRING,KEY_rewID }, 
                null, null, null, null, null);

i add here an row in table :

database.insert("1", encodedImageString, "8");
                System.out.println(sqlite_obj.getAllData());

log cat :

Answer 1

You are creating table with different name .

Change :

private static final String DATABASE_CREATE = 
            "create table sample (id text primary key,reviewID text not null  ,photostring text not null);";

with :

private static final String DATABASE_CREATE = 
            "create table " + DATABASE_TABLE +" (id text primary key,reviewID text not null  ,photostring text not null);";
