我試圖使用SQLite ATTACH DATABASE命令將一個SQLite數據庫附加到BlackBerry上。BlackBerry SQLite：將一個SQLite數據庫附加到另一個
Database d1, d2;
Statement st;
URI dbURI1 = URI.create("file:///SDCard/Databases/SQLiteExample/MyTestDatabase1.db")
if (DatabaseFactory.exists(dbURI1)) {
d1 = DatabaseFactory.open(dbURI1);
} else {
d1 = DatabaseFactory.create(dbURI1);
st = d1.createStatement("CREATE TABLE 'People' ('Name' TEXT, 'Age' INTEGER)");
st.prepare();
st.execute();
st.close();
}
URI dbURI2 = URI.create("file:///SDCard/Databases/SQLiteExample/MyTestDatabase2.db");
if (DatabaseFactory.exists(dbURI2)) {
d2 = DatabaseFactory.open(dbURI2);
} else {
d2 = DatabaseFactory.create(dbURI2);
st = d2.createStatement("CREATE TABLE 'People2' ('Name2' TEXT, 'Age2' INTEGER)");
st.prepare();
st.execute();
st.close();
d2.close();
}
st = d1.createStatement("ATTACH DATABASE '/SDCard/Databases/SQLiteExample/MyTestDatabase2.db' as SECOND_TABLE");
st.prepare(); //THROWS AN EXCEPTION "SQL logic error or missing database"
st.execute();
st.close();
當它試圖爲「附加數據庫」命令準備語句我發現了一個異常ATTACH DATABASE /SDCard/Databases/SQLiteExample/MyTestDatabase2.db' as SECOND_TABLE: SQLlogic error or missing database 。
是否可以在BlackBerry SQLite API中使用ATTACH DATABASE命令？
謝謝。
