如何使用绝对文件路径作为绑定参数?

How to use a absolute file path as binding parameter?

我尝试使用绝对文件路径作为绑定参数。但它抛出语法错误:

exports.up = async (knex: Knex): Promise<any> => {
  const dest2 =
    '/Users/ldu020/workspace/github.com/mrdulin/nodejs-pg-knex-samples/src/knex-migration/using-a-remove-csv-file/migrations/geotargets-2019-05-02.csv';

  await knex.raw(
    `
      copy t1_geotargets(criteria_id, criteria_name, canonical_name, parent_id, country_code, target_type, status)
      from ?? DELIMITER ',' CSV;
    `,
    [dest2]
  );
};

这是错误消息:

migration file "20190515121901_import-a-remote-csv-file.ts" failed
migration failed with error: 
  copy t1_geotargets(criteria_id, criteria_name, canonical_name, parent_id, country_code, target_type, status)
  from "/Users/ldu020/workspace/github"."com/mrdulin/nodejs-pg-knex-samples/src/knex-migration/using-a-remove-csv-file/migrations/geotargets-2019-05-02"."csv" DELIMITER ',' CSV;
   - syntax error at or near ""/Users/ldu020/workspace/github""

我该如何解决这个问题?

更新

我想我找到了问题所在。原因是 . 符号。但是不知道怎么处理。

这是不可能的,因为在标识符中,绑定句点被解释为 table 和列名的分隔符。

您必须手动输入 knex.raw(`... from "${dest2}" DELIMITER ...`)
