What is Smallint in MySQL?
SMALLINT − A small integer that can be signed or unsigned. If signed, the allowable range is from -32768 to 32767. If unsigned, the allowable range is from 0 to 65535. You can specify a width of up to 5 digits.
What is Float8 data type?
The *Float8 data type defines a floating-point field to 8 bytes. The decimal positions must be left blank. However, floating-point fields are considered to have decimal positions.
How big is a Smallint?
The SMALLINT data type stores small whole numbers that range from –32,767 to 32,767. The maximum negative number, –32,768, is a reserved value and cannot be used. The SMALLINT value is stored as a signed binary integer.
What is the difference between Smallint and integer?
INTEGER values have 32 bits and can represent whole numbers from –2 31–1 through 2 31–1. SMALLINT values have only 16 bits. They can represent whole numbers from –32,767 through 32,767.
What is BigInteger one?
BigInteger. An object whose value is one (1).
What is BigInt and Smallint?
The INTEGER and SMALLINT data types hold small whole numbers. They are suited for columns that contain counts, sequence numbers, numeric identity codes, or any range of whole numbers when you know in advance the maximum and minimum values to be stored.
Is long and BigInt same?
The equivalent of Java long in the context of MySQL variables is BigInt. In Java, the long datatype takes 8 bytes while BigInt also takes the same number of bytes.

Why is column int (4) being displayed as 0001?
Apr 12 ’11 at 11:04 81 Column INT(4), integer 1 would be displayed as 0001 ONLY if the column was also specified as zerofill. Otherwise, it will just be displayed as number 1, without extra digits. @Gaurav – don’t mix how mysql displays data and how it stores it, those are two different things.
What does the number in the brackets mean in an unsigned int?
An unsigned int has the max value of 4294967295 no matter if its INT (1) or int (10) and will use 4 bytes of data. So, what does the number in the brackets mean? It pretty much comes down to display, its called the display-width. The display width is a number from 1 to 255.
