Numeric data types The numeric data types are binary integer, decimal, decimal floating-point, and floating-point. The numeric data types are categorized as follows: Exact numeric data types: binary integer and decimal Decimal floating-point Approximate numeric data types: floating-point Binary intege...
col3: This column is of the BLOB (Binary Large Object) data type. BLOB columns are used to store very large binary data, such as pictures or sounds. They can hold large amounts of data, limited only by the database's storage capacity. DBMS Binary Types: Numeric Types: Numeric data t...
SQL data types define the type of value that can be stored in a table column. For example, if you want a column to store only integer values, you can define its data type as INT. SQL data types can be broadly divided into the following categories. Numeric data types such as: INT, ...
SQL查询,字段类型为NUMERIC SQL查询是一种用于从关系型数据库中检索数据的编程语言。它可以通过指定条件和规则来查询数据库中的数据,并返回满足条件的结果集。 字段类型为NUMERIC是一种用于存储数值类型数据的数据类型。它可以存储任意精度的数值,包括整数和小数。NUMERIC类型通常用于需要高精度计算或存储货币金额等需要精确...
Approximate-number data types for use with floating point numeric data. Floating point data is approximate; therefore, not all values in the data type range can be represented exactly. The ISO synonym forrealisfloat(24). float[(n)] Wherenis the number of bits that are used to store the ma...
