有一个字符串,它来自文本字段,有200个字符限制。在 Offacle DB s table 中,字段的最大值为200个字符。应用程序崩溃,它说它无法将212个字符写入最多200个字符的字段。问题明显出现在 DB 级别上,与其他带有相同表格和 CRUD 的数据库一样,它都运行良好。
我怀疑这个问题可能与编码差异有关,
SELECT * 来自NLS_DATABASE_PARameters;
两个数据库的结果都相同,在两种情况下,NLS_CHARACTERSET 都显示了AL32UTF8 的价值。有什么问题?
P. S. 它是 ASP. NET 应用程序,如果有帮助的话。
如果 NLS_LENCHTH_SEMENTICS 参数相同, 也许对列的定义不同: VARCHAR2( 200 BYTE) 和 VARCHAR2( 200 CHAR)?
呵呵。 呵呵。
