Question

我目前正在尝试使用pyorient填充orientdb图数据库。一般来说，一切都运作良好。但是，我偶然发现了我的一个命令的解析问题。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)

我收到以下错误：

如果我使用命令运行此命令，我也会收到错误：

但是我发现如果我不将original_abstract下的信息添加为一个集合，那么在使用命令时它会起作用：

>>> 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']

但是client.batch仍然无法正确处理：

直接在orientdb控制台中运行字符串ab也会产生相同的错误，但是在orientdb控制台中运行字符串aba工作正常，所以我无法理解为什么aba不能使用pyorient batch命令（我也设法运行aba）在orientdb控制台中作为开始/提交事务的一部分成功）。

有没有人理解为什么这个命令可以通过client.command而不是client.batch工作？我需要将此命令作为一批命令的一部分运行，因此需要找到一个修复程序.....理想情况下，我希望在字符串ab中使用命令，我将原始摘要添加为工作集，因为我需要跟踪匹配节点的任何新信息。

从我可以看到这是命令执行程序的解析限制，但请告诉我，如果我在这里做错了...

谢谢！

第一个错误显示您的命令中有文件结尾（EOF）字符，这可能不可见，如果从其他地方复制它是很常见的。
