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...
Wherenis the number of bits that are used to store the mantissa of thefloatnumber in scientific notation and, therefore, dictates the precision and storage size. Ifnis specified, it must be a value between1and53. The default value ofnis53. Decimal and Numeric Numeric data types that have f...
Numeric data types that have fixed precision and scale. [(p[,s])] andnumeric[(p[,s])] aredecanddec(p,s).numericis functionally equivalent todecimal. (scale) . Scale can be specified only if precision is specified. The default scale is 0; therefore, 0 <=s<=p. Maximum storage sizes...
4.1 数值类型 (Numeric Types) 数值类型用于存储整数和浮点数。这些类型确保数据在存储和计算时具有高效性和准确性。 **INT**:存储整数。例如,123。 CREATE TABLE example ( id INT, age INT ); **DECIMAL 或NUMERIC**:用于存储精确的小数。格式为 DECIMAL(M, D),其中 M 是数字总长度,D 是小数点后的位...
