What are the different data types in MySQL .explain any two?
MySQL supports all standard SQL numeric data types which include INTEGER, SMALLINT, DECIMAL, and NUMERIC. It also supports the approximate numeric data types (FLOAT, REAL, and DOUBLE PRECISION). The keyword INT is a synonym for INTEGER, and the keywords DEC and FIXED are synonyms for DECIMAL.

MySQL numeric data types
| Numeric Types | Description |
|---|---|
| INT | A standard integer |
| BIGINT | A large integer |
| DECIMAL | A fixed-point number |

SQL Data Types with example and explanation Character String Types. Boolean Type. Binary Types. Numeric Types.
What is data type of image in MySQL?
In MySQL, the preferred data type for image storage is BLOB. BLOB: Can handle up to 65,535 bytes of data. MEDIUMBLOB: The maximum length supported is 16,777,215 bytes. LONGBLOB: Stores up to 4,294,967,295 bytes of data.
What is data type What are the main objectives of data types in MySQL?
MySQL has all essential SQL numeric data types. These data types can include the exact numeric data types (For example, integer, decimal, numeric, etc.), as well as the approximate numeric data types (For example, float, real, and double precision). It also supports BIT datatype to store bit values.
What is enum data type in MySQL?
The ENUM data type in MySQL is a string object. It allows us to limit the value chosen from a list of permitted values in the column specification at the time of table creation. It is short for enumeration, which means that each column may have one of the specified possible values.

What are the different types of data in MySQL?
MySQL supports a number of SQL data types in several categories: numeric types, date and time types, string (character and byte) types, spatial types, and the JSON data type.
How are fixed point data types used in MySQL?
Fixed-Point Types. Fixed-Point data types are used to preserve exact precision, for example with currency data. In MySQL DECIMAL and NUMERIC types store exact numeric data values. MySQL 5.6 stores DECIMAL values in binary format. In standard SQL the syntax DECIMAL(5,2) (where 5 is the precision and 2 is the scale.
How to define double precision in MySQL data types?
DOUBLE (M,D) − A double precision floating-point number that cannot be unsigned. You can define the display length (M) and the number of decimals (D). This is not required and will default to 16,4, where 4 is the number of decimals. Decimal precision can go to 53 places for a DOUBLE. REAL is a synonym for DOUBLE.
What does m mean in MySQL for strings?
For integer types, M indicates the maximum display width. For floating-point and fixed-point types, M is the total number of digits that can be stored (the precision). For string types, M is the maximum length.
