Miscellaneous Types Hive还提供两种primitive data types,BOOLEAN和BINARY。和Java的Boolean相似,BOOLEAN只存储true或者false。 BINARY是字节数组,和很多关系型数据库的VARBINARY相似。BINARY存储在记录中,不想BLOB单独存储,可以在BINARY中包含任意字节序列,会原样存储,不会被解析成数字或者字符。 Complex Data Types Hive还支...
原来,在 int(M) 中,M 的值跟 int(M) 所占多少存储空间并无任何关系。 int(3)、int(4)、int(8) 在磁盘上都是占用 4 bytes 的存储空间。也就是说,int(M),必须和UNSIGNED ZEROFILL一起使用才有意义。如果整数值超过M位,就按照实际位数存储。只是无须再用字符 0 进行填充。 TINYINT:一般用于枚举数据,...
Converts the value of a specified instance of Decimal to its equivalent binary representation. GetHashCode() Returns the hash code for this instance. GetTypeCode() Returns the TypeCode for value type Decimal. IsCanonical(Decimal) Determines if a value is in its canonical representation. IsEvenIn...

たとえば、OracleDecimalインスタンスとOracleBinaryインスタンスを比較することはできません。OracleDecimalを異なるタイプと比較すると、ArgumentExceptionが表示されます。 値を持つすべてのOracleDecimalは、NULL値を持つOracleDecimalより大きい値とみなされます。 NULL値を含む2つのOracleDecimalは等し...
Just a point of interest : - Quoting form Wikipedia " Binary files are usually thought of as being a sequence of bytes, which means the binary digits (bits) are grouped in eights. " Therefore you are also correct to call a sequence of bits as being a binary sequence. Here is the wiki...
