使用整数参数执行查询的推荐方法是什么

是这样吗

int value = 10;
Cursor cursor = database.query(
    "TABLE_X", 
    new String[] { "COLUMN_A", "COLUMN_B" },
    "COLUMN_C = " + value,
    null,
    null,
    null,
    null);

int value = 10;
Cursor cursor = database.query(
    "TABLE_X", 
    new String[] { "COLUMN_A", "COLUMN_B" },
    "COLUMN_C = ?",
    new String[] { Integer.toString(value) },
    null,
    null,
    null);
还是这样：

int value = 10;
Cursor cursor = database.query(
    "TABLE_X", 
    new String[] { "COLUMN_A", "COLUMN_B" },
    "COLUMN_C = " + value,
    null,
    null,
    null,
    null);

int value = 10;
Cursor cursor = database.query(
    "TABLE_X", 
    new String[] { "COLUMN_A", "COLUMN_B" },
    "COLUMN_C = ?",
    new String[] { Integer.toString(value) },
    null,
    null,
    null);
或者别的什么？

带有

SelectionAgs：您可以在选择中包括？s，它将被值替换 从SelectionAgs中，按它们出现在所选内容中的顺序。这个 值将被绑定为字符串
