Pyorient批处理解析问题

Question

我目前正在尝试使用pyorient填充orientdb图形数据库。总的来说，一切都运行得很好。但是，我的一个命令遇到了一个解析问题。在Python中，如果我运行以下代码：

>>> ab = 'UPDATE Patent SET  primary_id = 676, original_abstract = set(original_abstract, "<p num=\\"0000\\">The present invention relates to compounds of the general formula (I) wherein\\n\\nR<sup>1</sup> is the group (A) or (B) or (C) or (D); R<sup>2</sup> is a non aromatic\\n\\nheterocycle, or is OR\' or N(R\\")<sub>2</sub>; R\' is lower alkyl,\\n\\nlower alkyl substituted by halogen or -(CH<sub>2</sub>)<sub>n</sub>-cycloalkyl;\\n\\nR\\" is lower alkyl; R<sup>3</sup> is NO<sub>2</sub>, CN or SO<sub>2</sub>R\';\\n\\nR<sup>4 </sup>is hydrogen, hydroxy, halogen, NO<sub>2</sub>, lower alkyl, lower\\n\\nalkyl, substituted by halogen, lower alkoxy, SO<sub>2</sub>R\' or C(O)OR\\";\\n\\nR<sup>5</sup>/R<sup>6</sup>/R<sup>7</sup> are hydrogen, halogen, lower alkyl\\n\\nor lower alkyl, substituted by halogen; X<sup>1</sup>/X<sup>1\\u00bf</sup>\\n\\nare CH or N, with the proviso that X<sup>1</sup>/X<sup>1\\u00bf</sup> are not simultaneously\\n\\nCH; X<sup>2</sup> is O, S, NH or N(lower alkyl); n is 0, l or 2; and to pharmaceutically\\n\\nactive acid addition salts and to their use in the treatment of neurological and\\n\\nneuropsychiatric disorders.</p>")  UPSERT WHERE primary_id = 676'
>>> client.batch(ab)

我得到以下错误：

如果我使用命令运行这个命令，我也会得到错误：

但是，我发现如果不将original_abstract下的信息作为集合添加，则使用命令时会起作用：

>>> aba = 'UPDATE Patent SET  primary_id = 676, original_abstract = "<p num=\\"0000\\">The present invention relates to compounds of the general formula (I) wherein\\n\\nR<sup>1</sup> is the group (A) or (B) or (C) or (D); R<sup>2</sup> is a non aromatic\\n\\nheterocycle, or is OR\' or N(R\\")<sub>2</sub>; R\' is lower alkyl,\\n\\nlower alkyl substituted by halogen or -(CH<sub>2</sub>)<sub>n</sub>-cycloalkyl;\\n\\nR\\" is lower alkyl; R<sup>3</sup> is NO<sub>2</sub>, CN or SO<sub>2</sub>R\';\\n\\nR<sup>4 </sup>is hydrogen, hydroxy, halogen, NO<sub>2</sub>, lower alkyl, lower\\n\\nalkyl, substituted by halogen, lower alkoxy, SO<sub>2</sub>R\' or C(O)OR\\";\\n\\nR<sup>5</sup>/R<sup>6</sup>/R<sup>7</sup> are hydrogen, halogen, lower alkyl\\n\\nor lower alkyl, substituted by halogen; X<sup>1</sup>/X<sup>1\\u00bf</sup>\\n\\nare CH or N, with the proviso that X<sup>1</sup>/X<sup>1\\u00bf</sup> are not simultaneously\\n\\nCH; X<sup>2</sup> is O, S, NH or N(lower alkyl); n is 0, l or 2; and to pharmaceutically\\n\\nactive acid addition salts and to their use in the treatment of neurological and\\n\\nneuropsychiatric disorders.</p>"  UPSERT WHERE primary_id = 676'
>>> client.command(aba)
['1']

然而，client.batch仍然不能正确处理这一点：

>>> client.batch(aba)

在orientdb控制台中直接运行string ab也会给出相同的错误，但是在orientdb控制台中运行string aba可以很好地工作，所以我不能理解为什么aba不能使用pyorient批处理命令(我还成功地在orientdb控制台中作为begin/commit事务的一部分运行了aba )。

有人知道为什么这个命令通过client.command而不是client.batch工作吗？我需要将此命令作为一批命令的一部分运行，因此需要找到修复程序.....理想情况下，我希望在string ab中使用命令，因为我需要跟踪匹配节点的任何新信息，因此我需要将原始摘要添加为一个集合来工作。

根据我所看到的，这是命令执行程序的解析限制，但如果我在这里做错了什么，请告诉我……

谢谢！！

第一个错误显示您的命令中有文件结束(EOF)字符，该字符可能看不见，如果它是从其他地方复制的，这是很常见的。
