Explanation: There are various numeric datatypes in MySQL. Some of them are TINYINT, SMALLINT, BIGINT, FLOAT, DOUBLE and BIT. ‘FLOAT’ is for single precision floating point numbers unlike DOUBLE.

Explanation: MySQL has a variety of string datatypes for use. Strings can hold arbitrary binary data. All the four options are string type names. BINARY is used for a fixed length binary string.

Explanation: In MySQL, there are a wide variety of string datatypes for use. Strings can even hold image and sound data. All the four options are string type names. VARCHAR represents a variable length non binary string.

Explanation: MySQL has some variety of date and time datatypes. These datatypes are crucial for representing records in a table. The ‘TIME’ type represents a time value, stored in the ‘hh:mm:ss’ format.

Explanation: In MySQL, there are many spatial datatypes available for use. Some examples are GEOMETRY, POINT, LINESTRING and POLYGON. The LINESTRING type is used to represent a curve.

Explanation: UNSIGNED and ZEROFILL are allowable only for numeric types, and CHARACTER SET and COLLATE are allowable only for non-binary string types. These are type specific attributes.

Explanation: For every data type except the BLOB and TEXT types, spatial types, or columns with the AUTO_INCREMENT attribute, a DEFAULT def_value clause can be specified to keep a default value for a column.

Explanation: The DEFAULT def_value clause can be specified for every data type except the BLOB and TEXT types, spatial types, or columns with the AUTO_INCREMENT attribute. The def_value holds the default.

Explanation: Numeric datatypes in MySQL are many. Each numeric datatype used in MySQL have their own ranges in terms of bits. The INT datatype stores signed and unsigned values of 32 bits.

Explanation: In MySQL, the numeric datatypes are many. A numeric datatype used in MySQL has its own range in terms of bits. The SMALLINT datatype stores signed and unsigned values of 16 bits.
