我作为查询
的一部分关注nameQuery = " AND (lower(templateInformation.name) LIKE lower('%' || :name || '%'))";
当只有这个名称参数超过4001个字符时，它将抛出以下异常。
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article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，则不会有任何事情。表列类型为nvarchar（255）。 有人可以解释这种情况吗？
