Specifies whether to execute the query with the option that avoids truncation of large variable length data types 指定是否使用可避免截断大型可变长度数据类型（ varchar ( max )
The downside for variable length columns is that some operations are not as efficient as those on fixed length columns 与固定长度列相比，可变长度列的缺点是一些操作的效率不高。
Variable length columns reduce database size because they take only what is required to store the actual value 由于可变长度列仅占用存储实际值所需的空间，所以可减小数据库大小。
Name is a fixed - length unicode graphic column and description is a variable - length unicode graphic column Name是一个固定长度的unicode图形列，而description是一个可变长度的unicode图形列。
The cipher supports variable length keys , although the openssl implementation of cast is restricted to 128 - bit keys 这种加密算法支持可变长度的密钥，但是openssl为cast实现的密钥长度限制在128位。
A tagged message also has the space overhead of allocating variable length data elements to store the retrieved data values 带标记的消息还需要分配可变长度的数据元素来存储检索数据值而带来的空间开销。
When you design your tables , it helps to understand the tradeoffs of using variable length columns versus fixed length columns 在设计表时，了解使用可变长度列和使用固定长度列各有哪些利弊是非常有用的。
Fixed - length records are preferred over varying length records , because the db2 code is optimized for processing fixed - length records 固定长度的记录要优于可变长度的记录，因为db2代码专门为处理固定长度的记录进行优化。
For example , if a variable length column starts small and an update causes it to grow significantly , the record might have to be relocated 例如，如果可变长度列开始时很小，而某update子句使其显著增大，则可能就要重新定位记录。
The purpose of this attribute is to modify how strings in structures and non - local variables are used by methods or api calls that recognize the 是信息性的属性，不能用于将可变长度字符串转换为固定长度字符串。此属性的作用是修改那些识别
