In a binary format, true refers to 1 and false — to 0. As a rule, they are used for logical operations. MySQL does not have a boolean or bool data type. When you create a table with a boolean data type, MySQL outputs data as 0, if false, and 1, if true. The Float data types represent single-precision approximate numeric values that require 4 bytes for storage. The Double data types refer to the floating-point numeric data types and use 8 bytes to store double-precision values. To sum up, decimals are better to use for fixed amounts, such as monetary and financial information price, salary, etc, , while float and double — for approximate calculations where rounding values might have a negative impact.

The BIT data type is used to store binary values in the column and accepts either 0 or 1. The range of bit values for the column goes from 1 to If the range is not set, the default value will be 1. In the days column, 1 serves as a working day and 0 — as a day-off.

Suppose in April, employees can have two additional day-offs. So, to retrieve data being converted to binary, we need to use the BIT function and view the result. Then, insert a new row into the table and retrieve data. Finally, we will add to the table the year when an employee was certified and declare the YEAR data type for the column.

Spatial data types store geometry and geography values in the table column. Starting with version 5. The JSON format allows for a quick search of values within the document using a key or array index, which, in turn, will improve overall performance and optimize storage.

In addition, JSON helps validate documents and in case of invalid values, you will get an error. The maximum size is 1GB. Considering a list of MySQL data types discussed in the article, it can be important to change default data types so that they suit our needs best. For our example, we are going to use the employees table. Then, execute the query by clicking Execute on the SQL toolbar. Alternatively, you can refresh the list of tables in Database Explorer and see the changed data type.

In the article, we have reviewed MySQL data types with examples, such as string, numeric, date and time, spatial, and JSON, as well as explored data types each group includes. You can also use the following articles to learn how to make the development process much faster and easier with dbForge Studio for MySQL:. Download a day free trial version to assess the features of dbForge Studio for MySQL to be convinced that it is worth purchasing the full license of the tool in order to improve productivity and database development and management in the most efficient way.

MySQL Tools. Usually, they may be used for IDs or counting numbers. Decimals represent numbers with fractions and store exact numeric values in the column. They can be signed and unsigned and are usually used for columns that store monetary values. In the comparison with the floating-point numbers, decimals are more accurate.

Floating-point represent numbers with fractions but do not store exact numeric values. They can be signed and unsigned. Floating-point numeric values use a double-precision bit format or a single-precision bit format to store data. They may lead to a loss of precision during arithmetic operations. Integer Data Types Integer data types are numeric values without fractions.

Boolean Data Type The boolean data types can only accept either true or false values. Float Data Type The Float data types represent single-precision approximate numeric values that require 4 bytes for storage. Double Data Type The Double data types refer to the floating-point numeric data types and use 8 bytes to store double-precision values.

Conversion of the value from the zone of the connection server to UTC takes place. The table provides a description per spatial data type. Conclusion In the article, we have reviewed MySQL data types with examples, such as string, numeric, date and time, spatial, and JSON, as well as explored data types each group includes.

The initial overviews are intentionally brief. Consult the more detailed descriptions for additional information about particular data types, such as the permissible formats in which you can specify values. 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.

The maximum permissible value of M depends on the data type. D applies to floating-point and fixed-point types and indicates the number of digits following the decimal point the scale. The fsp value, if given, must be in the range 0 to 6. A value of 0 signifies that there is no fractional part. If omitted, the default precision is 0. Square brackets [ and ] indicate optional parts of type definitions.

Numeric Type Attributes. Out-of-Range and Overflow Handling. Date and Time Data Type Syntax. Fractional Seconds in Time Values. Conversion Between Date and Time Types.
