推荐答案

一些资源:

  • https://github.com/oracle/node-oracledb/tree/master/examples 有 LOB 示例,例如 lobinsert1.js 和 lobinsert2.js

  • https://github.com/oracle/node-oracledb/tree/master/examples has LOB examples, for example lobinsert1.js and lobinsert2.js

node-oracledb 手册中有大量关于在 node-oracledb 中使用 LOB 的文档,请参阅 使用 CLOB、NCLOB 和 BLOB 数据.

There is plenty of documentation on using LOBs in node-oracledb in the node-oracledb manual, see Working with CLOB, NCLOB and BLOB Data.

例如:

    // Insert a CLOB
    const str = fs.readFileSync(clobInFileName, 'utf8');
    result = await connection.execute(
      `INSERT INTO no_lobs (id, c) VALUES (:id, :c)`,
      { id: 1, c: str }
    );
    if (result.rowsAffected != 1)
      throw new Error('CLOB was not inserted');
    else
      console.log('CLOB inserted from ' + clobInFileName);

在您的情况下,您将从您的网络服务而不是磁盘读取 str文件.由于我不知道该网络服务是什么,因此无法发表更多评论.

In your case you would read str from your web service instead of a disk file. Since I don't know what that web service is, I can't comment more.
