水晶报表表的别名中含有特殊字符的处理-优快云博客

本文介绍了在Crystal Reports中因数据库表别名包含无效字符而导致的Query Engine错误，并提供了通过修改注册表项来排除特定字符的方法。默认情况下，注册表项包含一系列被视为无效的字符，若要在别名中使用这些字符，则需从注册表值数据中移除。

In Crystal Reports, the following error message is displayed when an invalid character is used in the database

table alias name: Query Engine Error: “The alias requested “my\aliasname”, contains a combination of

characters which is not considered to be valid”. The invalid characters are: .:{}()@&$#^!*~|%", -+>,/\`

New Behavior:

A registry subkey now exists that Crystal Reports uses to identify what characters are considered to be invalid

for alias names. By default, the registry subkey value data contains the following characters:

.:{}()@&$#^!*~|%"- If you wish to use one of the invalid characters in an alias name, remove the desired

character from the registry subkey value data.

The registry subkey is:

HKEY_LOCAL_MACHINE\Software\Crystal Decisions\9.0\Crystal

Reports\Database\InvalidAliasCharList

The issue is corrected in the following component version, or later.
