The signed range is -1to 127. A medium-sized integer. INTEGER is a synonym for INT. Very small integer value that is equivalent to TINYINT (1). Signed values range from -1to 127.

Unsigned values range from to 255. SMALLINT (m) Small integer value. SIGNED , UNSIGNED and ZEROFILL. What is the difference between tinyint, smallint, mediumint, bigint and int in MySQL? In what cases should these be used?

Functions return bigint only if the parameter expression is a bigint data type. SQL Server does not automatically promote other integer data types ( tinyint , smallint , and int) to bigint. One the production server, the above query (no single quotes) works. MariaDB : TINYINT : signed range is -1to 127.

MySQL returns it without decimals. This can cause a problem if you are using UNIX_TIMESTAMP() as a partitioning function. About the INT, TINYINT. These are different data types, INT is 4-byte number, TINYINT is 1-byte number.

The following table shows the required storage and range for each integer type. Numeric Type Attributes. Required Storage and Range for Integer Types Supported by MySQL.

While designing the database using phpMyAdmin, I found that I have both the BOOLEAN datatype and the TINYINT datatype. I went through different articles, some said TINYINT is the same as BOOLEAN, no difference. Some say BOOLEAN is converted into TINYINT in MySQL. MY question is, if they both are same why do there exist two? NOT NULL, amount DECIMAL(2) DEFAULT 0. If you attempted to cast a tinyint value to smallint in a query, you would never expect that to fail, because every tinyint is also a smallint.

Smaller types take less space so more rows fit in a page resulting in less space taken both on disk and in memory. Of course, if you choose too small a type your application will fail. Consider also BIGINT for when values larger than 14486(or smaller than -1448647) might be needed.

ZEROFILL will fill numbers that are less than the display size with zeroes in front of them. So, it is very crucial to select the correct data type while creating table. Hope the above differences will help you in selecting the correct data type while creating the table.

Data-wise, tinyint (1), tinyint (2), tinyint (3) etc. SQLines SQL Converter - SQL scripts conversion tool. As other noted the number in parenthesis is merely a display width hint.

Here, tinyint (1) can take a special. Although Impala rejects attempts to insert out-of-range values into such columns, if you create a new table with the CREATE TABLE. These types are synonyms for TINYINT (1). A value of zero is considered false.

Smallint Data type in Cassandra Query Language ( CQL) takes Bytes to store the value. Smallint data type in Cassandra Query Language( CQL) can store data from -2^(-3768) to 2^15-(3767). Use CAST() to convert to STRING or TIMESTAMP. In MySQL, the best way to guarantee two-digit numbers is to build a table, insert all the valid two-digit numbers, and set a foreign key reference to it.

Seems to me like TINYINT width no display width would make more sense.
