这是我在DatabaseHelper类中所做的事情。
public DatabaseHelper(Context context)
{
super(context, DATABASENAME, null, VERSION);
context.openOrCreateDatabase(DATABASENAME, context.MODE_PRIVATE, null);
}
@Override
public void onCreate(SQLiteDatabase db) {
String queryProductsAllData = "CREATE TABLE `"+TABLE_PRODUCTS+"` (\n" +
"\t`"+COLUMN_BRANDID +"`\tINTEGER,\n" +
"\t`"+COLUMN_PRODUCTID +"`\tINTEGER,\n" +
"\t`"+COLUMN_PRODUCTCODE +"`\tINTEGER,\n" +
"\t`"+COLUMN_PIECESINCASE +"`\tINTEGER,\n" +
"\t`"+COLUMN_PRODUCT_STOCK_UNITS +"`\tINTEGER DEFAULT 0,\n" +
"\t`"+COLUMN_PRODUCTADDEDBY +"`\tINTEGER,\n" +
"\t`"+COLUMN_BRANDCODE +"`\tTEXT,\n" +
"\t`"+COLUMN_BRANDNAME +"`\tTEXT,\n" +
"\t`"+COLUMN_PRODUCTNAME +"`\tTEXT,\n" +
"\t`"+COLUMN_PRODUCTSHORTNAME +"`\tTEXT,\n" +
"\t`"+COLUMN_PIECENETVOLUME +"`\tTEXT,\n" +
"\t`"+COLUMN_PRICEPOINT +"`\tTEXT,\n" +

"\t`"+COLUMN_PRODUCTADDEDON +"`\tTEXT,\n" +
"\t`"+COLUMN_PRODUCTSTATUS +"`\tINTEGER\n" +
");";
db.execSQL(queryProductsAllData);
}
@Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion)
{
db.execSQL("DROP TABLE IF EXISTS "+TABLE_PRODUCTS);
}

这是我获取到的日志。
