错误原因：

bash 复制代码

  wheres.push(`'$${params.length + 1}' = ANY(string_to_array(ancestors, ','))`)
  params.push(deptId)

deptId是整数型，需要转成字符串型参与和ANY函数的匹配，但是deptId转字符串不应该在wheres的模板中加单引号'进行，而是在params中转成字符串型后，让pgsql去替换，正确的是

bash 复制代码

  wheres.push(`$${params.length + 1} = ANY(string_to_array(ancestors, ','))`)
  params.push(deptId + '')
