作为查询的一部分，我已经关注
nameQuery = " AND (lower(templateInformation.name) LIKE lower('%' || :name || '%'))";
当仅此名称参数超过 4001 个字符时，将引发以下异常。
Caused by: se.cambio.platform.sdk.common.service.ServiceException: org.hibernate.exception.GenericJDBCException: could not extract ResultSet [at org.hibernate.exception.internal.StandardSQLExceptionConverter.convert():54], Caused by: java.sql.SQLException: The data types varchar and ntext are incompatible in the add operator.

我发现这篇文章解释了为什么会发生这种情况。但在我的情况下，如果 name 参数的字符小于或等于 4001，则不会发生任何事情。并且表列类型是 nvarchar(255)。有人可以解释这种情况吗？
