正则表达式/解析 PostgreSQL 名称

Question

通过 PostgreSQL名称和标识符，我试图找出以下内容：

\n\n

是否可以实现正则表达式（或以其他方式解析它）来检查 PostgreSQL 名称/标识符是否需要用双引号引起来？如果可能的话，还要检查它是否是 Unicode 样式的名称。

\n\n

我需要将标识符名称注入 SQL 查询中，并且仅当名称需要时，我才想将其括在双引号中，因为我读到，在不需要的地方添加引号实际上会更改名称格式（请参阅下面的更新） ）。

最终，我需要实现以下功能：

\n\n

function prepareSQLName(name) {\n\n    if (/* this is a regular name*/) {\n        return name;\n    }\n\n    if (/* this is a unicode name */) {\n        return \'U&"\' + name + \'"\';\n    } else {\n        /* needs double quotes only */\n        return \'"\' + name + \'"\';\n    }\n}\n

\n\n

主要关注点之一 - 处理非英文名称。例如，以下是一个完全有效的 PostgreSQL（俄语），不需要将任何内容括在双引号中：

\n\n

create table \xd0\xb6\xd0\xb8\xd1\x80\xd0\xb0\xd1\x84\xd1\x8b(\xd0\xb2\xd0\xb5\xd1\x81 int, \xd1\x80\xd0\xbe\xd1\x81\xd1\x82 int, \xd0\xb2\xd0\xbe\xd0\xb7\xd1\x80\xd0\xb0\xd1\x81\xd1\x82 int, \xd0\xb8\xd0\xbc\xd1\x8f text);\nselect \xd0\xb8\xd0\xbc\xd1\x8f, \xd0\xb2\xd0\xb5\xd1\x81 from \xd0\xb6\xd0\xb8\xd1\x80\xd0\xb0\xd1\x84\xd1\x8b order by \xd1\x80\xd0\xbe\xd1\x81\xd1\x82;\n

\n\n

更新2：

\n\n

举例说明为什么它如此重要......

\n\n

CREATE TABLE Test1(name text);\n\n-- can be queried as:\nSELECT * FROM Test1\nSELECT * FROM test1\nSELECT * FROM "test1"\n\n-- but not as:\nSELECT * FROM "Test1"\n

\n\n

另一个：

\n\n

CREATE TABLE "Test2"(name text);\n\n-- can be queried only as:\nSELECT * FROM "Test2"\n

\n\n

对于 Unicode 格式的名称（需要U&在前面），情况会变得更加棘手。

笔记：

\n
1. 我们需要xregexp模块，因为内置RegExp类不支持Unicode 类别（\\pLakap{L}和\\pMaka\\p{M}）的测试。尽管如此，检测字母并不是 100% 清晰（请参阅“检测字母的详细信息”）。
\n
2. 关键词列表取自此处。使用此列表可能不是理想的解决方案，因为并非所有这些标识符实际上都被禁止在所有可能的情况下使用（即有时它可能引用允许不加引号的表名称，例如abs）。另一方面，如果不向函数添加namePurpose第二个参数，则无法理想地解决此任务prepareSQLName（因为其中一些标识符仅允许在特定情况下使用）。
\n

3. 如果您希望非英语字母保持非转义，则不需要对非 ASCII 进行特殊处理（它们可能是非转义的，如 中所示SELECT "\xd1\x96\xd0\xbc\'\xd1\x8f" FROM \xd0\xba\xd0\xbe\xd1\x80\xd0\xb8\xd1\x81\xd1\x82\xd1\x83\xd0\xb2\xd0\xb0\xd1\x87\xd1\x96）。唯一需要检查的是包含字母/数字/ _/以外的内容的标识符$应该被引用（如"\xd1\x96\xd0\xbc\'\xd1\x8f"）。但如果您愿意，您还可以转义所有非 ASCII 字符：
