jdbc - QueryRunner 返回“ORA-00972：标识符太长”，将值作为参数传递

Question

我不明白为什么在以下代码中使用绑定变量会失败，但硬编码它可以工作。
如果我只放置一个rownum < 2子句而不是 id 子句，它也可以工作。

无：在代码的其他部分使用绑定变量就可以了。

数据库信息：

Oracle 12c
ID 列是 VARCHAR2(34)。

作品：

    org.apache.commons.dbutils.QueryRunner remote = ...;
    String searchId = "13056899429626141414864120X"
    String sql = toString("SELECT * FROM ", remoteOwner, ".table_name WHERE id = '"+searchId+"'");
    result = remote.query(sql, new MapListHandler());

失败：

    org.apache.commons.dbutils.QueryRunner remote = ...;
    String searchId = "13056899429626141414864120X"
    String sql = toString("SELECT * FROM ", remoteOwner, ".table_name WHERE id = ?");
    result = remote.query(sql, new MapListHandler(), searchId);

例外：

Exception in thread "main" java.sql.SQLException: ORA-00972: identifier is too long
 Query: SELECT * FROM SCHEMA_NAME.table_name WHERE id = ? Parameters: [13056899429626141414864120X]

根异常（吞咽）：
