Finally, both TDS and Custom Wire Format (CWF) allow the automatic truncation of oversize fixed length string fields when a message is output.

最后，在输出消息时，TDS和自定义有线格式(CWF)允许自动截断过大的固定长度字符串字段。

The md5() function hashes whatever string is fed to it and turns it into a 32-character fixed-length string.

md5() 函数可以散列反馈的任何字符串，并将其转变为固定长度为 32 个字符的字符串。

The first approach can be used if the intermediate result that is to be computed has a fixed length and can easily be encoded in the binary string returned from the computeAggregate function.

如果待计算的中间结果长度固定，而且可以很容易地编为二进制串返回给computeaggregate函数，可以用第一种方法。
