What does Tinyint mean in SQL?
A TINYINT is an 8-bit integer value, a BIT field can store between 1 bit, BIT(1), and 64 bits, BIT(64).
What does Tinyint 2 mean?
It means display width. Whether you use tinyint(1) or tinyint(2), it does not make any difference. I always use tinyint(1) and int(11), I used several mysql clients (navicat, sequel pro). It does not mean anything AT ALL! I ran a test, all above clients or even the command-line client seems to ignore this.
What is data type Tinyint?
Remarks. The TINYINT data type is an exact numeric data type; its accuracy is preserved after arithmetic operations. You can explicitly specify TINYINT as UNSIGNED, but the UNSIGNED modifier has no effect as the type is always unsigned. The range for TINYINT values is 0 to 28 – 1, or 0 to 255.
Can BigInt be null?
If an integer value is too large to be represented as a BIGINT , use a DECIMAL instead with sufficient digits of precision. NULL considerations: Casting any non-numeric value to this type produces a NULL value. Partitioning: Prefer to use this type for a partition key column.
What’s the difference between TINYINT 1 and TINYINT 2?
Data-wise, tinyint (1), tinyint (2), tinyint (3) etc. are all exactly the same. They are all in the range -128 to 127 for SIGNED or 0-255 for UNSIGNED. As other answers noted the number in parenthesis is merely a display width hint. You might want to note, though, that application=wise things may look different.

How to check the bounds of the TINYINT type?
For a convenient and automated way to check the bounds of the TINYINT type, call the functions MIN_TINYINT () and MAX_TINYINT () . If an integer value is too large to be represented as a TINYINT, use a SMALLINT instead.
What is the JDBC TINYINT type in Java?
The JDBC type TINYINT represents an 8-bit unsigned integer value between 0 and 255. The corresponding SQL type, TINYINT, is currently supported by only a subset of the major databases. The recommended Java mapping for the JDBC TINYINT type is as either a Java byte or a Java short .
