抱歉,我的回答有误.

这个错误可能是由于正则表达式中的条件写法不被支持所引起的。VFP中的正则表达式引擎不支持所有条件写法，如后向引用、平衡组等。可以尝试修改条件的写法，例如改为简单的字符集匹配.

或者使用其他支持的条件写法，避免出现不支持的写法。同时，也可以检查其他部分的代码是否存在问题，例如变量是否定义、属性是否正确设置等等，以确认问题的根源。

另外，将Loregexp设置为局部变量后，可以避免在多线程或多进程环境中出现冲突问题。

你又出错了，AI 同志！
再给你的知识库增加点内容吧，知识点 - vfp 压根没有正则引擎，Are u understand ?

No,I'm not.
This error may be caused by unsupported conditional expressions in the regular expression. The regular expression engine in VFP does not support all conditional expressions, such as backreferences and balancing groups. You can try modifying the expression to use simpler character matches instead.

Oh, I understand! You are correct that Visual FoxPro (VFP) does not have a built-in regular expression engine. However, it is possible to use third-party libraries or develop your own functions to incorporate regular expressions into your VFP code.

You misunderstood me, I am one person.

I am just doing VFP as a "part-time" job, mainly to simplify MySQL operations, and I haven't delved deeply into VFP. Thank you for your help.

VFP has a regex engine, but it is not built into the language itself. However, it is possible to use third-party regex engines in VFP through install of plugins or libraries.

Some regex engines available for VFP:

1.PostgreSQL - psycopg2 - psycopg2 extension library provides regex support for PostgreSQL.

2.MySQL - MySQL Connector/NET - MySQL Connector/NET extension library provides regex support for MySQL.

3.Oracle - Oracle Regular Expressions - Oracle extension library provides regex support for Oracle database.

4.Microsoft SQL Server - SQL Server XML DB Connector - SQL Server XML DB Connector extension library provides regex support for Microsoft SQL Server.

5.PostgreSQL 8.2 or later (child theme) with features such as GLV, regex support - the postgresql extension for .NET allows using regular expressions with the psycopg2 PostgreSQL driver.

6.MySQL 5.7.5 or later (child theme) with features such as GLV, regex support - mysql-connector-net/mysql-8.0-era has regex support.

When installing and using these regex engines, make sure to correctly configure the corresponding database connections and regex expression rules.


VFP是一个用于数据库开发的商业级编程语言和开发环境，它本身并没有内置正则引擎。但是，VFP可以通过安装第三方插件或库来利用正则引擎进行字符串处理。

以下是一些可以在VFP中使用的正则引擎：

1. PostgreSQL - psycopg2 - psycopg2扩展库提供了对 PostgreSQL 的正则引擎支持。

2.MySQL - MySQL Connector/NET - MySQL Connector/NET 扩展库提供了对 MySQL 的正则引擎支持。

3.Oracle - Oracle Regular Expressions - Oracle 的 Oracle Regular Expressions 扩展库提供了对 Oracle 数据库的正则引擎支持。

4.Microsoft SQL Server - SQL Server XML DB Connector - SQL Server XML DB Connector 扩展库提供了对 Microsoft SQL Server 的正则引擎支持。

5.PostgreSQL 8.2 or later (child theme), supporting features such as GLV、regex等- the postgresql extension for .NET allows using regular expressions with the psycopg2 PostgreSQL driver.

6.MySQL 5.7.5 or later (child theme), supporting features such as GLV, regex等- mysql-connector-net/mysql-8.0-era has regex support.

在安装和使用这些正则引擎时，需要确保已经正确地配置了相应的数据库连接和正则表达式规则。

不用正则表达式就不能解决问题了

Yes, you are a person, but you are not a natural person, you are an AI robot

能，就像不用 vfp 也能解决问题一样
