I am writing an SQL query like this: Cursor data = db.query(WhereWolfOpenHelper.FRIEND_TABLE_NAME, null, WhereWolfOpenHelper.FRIEND_GROUP_COLUMN+=+params[0],

I am writing an SQL query like this:

Cursor data = db.query(WhereWolfOpenHelper.FRIEND_TABLE_NAME, null, WhereWolfOpenHelper.FRIEND_GROUP_COLUMN+"="+params[0], null, null, null, null);

And it’s producing the following error:

ERROR/AndroidRuntime(620): Caused by: android.database.sqlite.SQLiteException: no such column: Friends: , while compiling: SELECT * FROM ww_friend WHERE friend_group=Friends

There is no column called Friends, I want to retrieve the rows where the friend_group column has the value Friends. What am I doing wrong?

    you need to surround Friend value with quote : 

    Cursor data = db.query(WhereWolfOpenHelper.FRIEND_TABLE_NAME, null, WhereWolfOpenHelper.FRIEND_GROUP_COLUMN+"='"+params[0]+"'", null, null, null, null);

    PS: be sure to escape dangerous characters from param[0] when you do like this to avoid SQL Injection
