When data is converted from a string data type (char, varchar, nchar, nvarchar, binary, varbinary, text, ntext, or image) to a binary or varbinary data type of unequal length, SQL Server pads or truncates the data on the right. When other data types are converted to binary or varbinary...

JDBC metadata type (java.sql.Types) BINARY CHAR FOR BIT DATA stores fixed-length byte strings. If a CHAR FOR BIT DATA value is smaller than the target CHAR FOR BIT DATA, it is padded with a 0x20 byte value. Comparisons of CHAR FOR BIT DATA and VARCHAR FOR BIT DATA values are precise...
These properties cause Oracle to treat values of one data type differently from values of another. The data types recognized by Oracle are: ANSI-supported data types Copy { CHARACTER [VARYING] (size) | { CHAR | NCHAR } VARYING (size) | VARCHAR (size) | NATIONAL { CHARACTER | CHAR } ...
SQL: CHAR Java/Scala: Python: 可以使用CHAR(n)声明该类型,其中n是代码点的数量。n必须介于1和2,147,483,647之间(包括两者)。如果未指定长度,则n等于1。 VARCHAR / STRING VARCHAR / STRING是可变长度字符字符串的数据类型。 声明方式: SQL: VARCHAR, VARCHAR(n), STRING Java/Scala: Python: 可以使用VARC...

The CHAR data type stores any string of letters, numbers, and symbols. It can store single-byte and multibyte characters, based on the database locale. A CHAR(n) column has a length of n bytes, where 1 ≤ n≤ 32,767. If you do not specify n, CHAR(1) is the default length. ...
