データベースからデータを取得できませんでした。以下の私のSQLクエリとLogcatエラー AndroidのSQLクエリデータベースのデータを取得しようとしていません

SQLクエリ

[Android Database Cursor Null Valuesを渡す]の重複可能性があります（http://stackoverflow.com/questions/7880751/android-database-cursor-passing-null-values） –

SQLクエリ不足しているスペースです。この：

FROM tbl_pre_testSELECT tbl_finger.templateFROMtbl_finger WHERE tbl_pre_test.ID

は、このする必要があります：

FROM tbl_pre_test SELECT tbl_finger.template FROM tbl_finger WHERE tbl_pre_test.ID
