In this articleApplies to: Binary data types of either fixed length or variable length. Argumentsbinary [ ( n ) ]Fixed-length binary data with a length of n bytes, where n is a value from 1 through 8,000. The storage size is n bytes. varbinary [ ( n | max ) ]Variable-length binary data. n can be a value from 1 through 8,000. max indicates that the maximum storage size is 2^31-1 bytes. The storage size is the actual length of the data entered + 2 bytes. The data that is entered can be 0 bytes in length. The ANSI SQL synonym for varbinary is binary varying. RemarksThe default length is 1 when n isn't specified in a data definition or variable declaration statement. When n isn't specified with the
Convert binary and varbinary dataWhen converting data from a string data type to a binary or varbinary data type of unequal length, SQL Server pads or truncates the data on the right. These string data types are:
When other data types are converted to binary or varbinary, the data is padded or truncated on the left. Padding is achieved by using hexadecimal zeros. Converting data to the binary and varbinary data types is useful if binary data is the easiest way to move around data. At some point, you might convert a value type to a binary value of large enough size and then convert it back. This conversion always results in the same value if both conversions are taking place on the same version of SQL Server. The binary representation of a value might change from version to version of SQL Server. You can convert int, smallint, and tinyint to binary or varbinary. If you convert the binary value back
to an integer value, this value will be different from the original integer value if truncation has occurred. For example, the following SELECT statement shows that the integer value
However, the following
The following batch shows that this silent truncation can affect arithmetic operations without raising an error:
The final result is Note Conversions between any data type and the binary data types are not guaranteed to be the same between versions of SQL Server. See also
Which database data type is a collection of binary data stored in a single field of a database?A binary large object (BLOB or blob) is a collection of binary data stored as a single entity.
Which part of a database is where a single piece of data is stored?1) In a database table, a field is a data structure for a single piece of data. Fields are organized into records, which contain all the information within the table relevant to a specific entity.
What is relational database and nonA relational database is the database management system in which data is stored in distinct tables from where they can be accessed or reassembled in different ways under user-defined relational tables, whereas a Non-Relational Database is the database architecture that is not built around tables.
What are the two types of data stored by the database system?Two types of database structure. A flat file database stores data in a plain text file, with each line of text typically holding one record. ... . A relational database contains multiple tables of data with rows and columns that relate to each other through special key fields.. |
