- The RAND function will return a value between 0 and 1 (not inclusive), so value > 0 and value < 1.
- The RAND function will return a completely random number if no seed is provided.
- The RAND function will return a repeatable sequence of random numbers each time a particular seed value is used.
Which is faster in or exists in SQL?
These "known problems" were:
- Schema changes lock tables for a long time.
- There are no data types that are convenient for loosely defined data, and as a side story to that.
- No good data types and ways to deal with tree structured data or other hierarchical data structures.

What does int 10 mean in SQL?
INT(10) means you probably defined it as INT UNSIGNED . So, you can store numbers from 0 up to 4294967295 (note that the maximum value has 10 digits, so MySQL automatically added the (10) in the column definition which (10) is just a format hint and nothing more. It has no effect on how big number you can store).
What is data type int?
The INTEGER data type stores whole numbers that range from -2,147,483,647 to 2,147,483,647 for 9 or 10 digits of precision. The number 2,147,483,648 is a reserved value and cannot be used. The INTEGER value is stored as a signed binary integer and is typically used to store counts, quantities, and so on.
What is int and VARCHAR in SQL?
The VARCHAR data type accepts character strings, including Unicode, of a variable length is up to the maximum length specified in the data type declaration. A VARCHAR declaration must include a positive integer in parentheses to define the maximum allowable character string length.
How big is an int in SQL?

What is int type in MySQL?

What is float data type?
They consist of a significant (a signed numeric value) and an exponent (a signed integer that specifies the magnitude of the significant). These data types have a precision, or a positive integer that defines the number of significant digits (exponent of the base of the number).
What is the exact data type in SQL?
In SQL, numbers are defined as either exact or approximate. The exact numeric data types are SMALLINT, INTEGER, BIGINT, NUMERIC (p,s), and DECIMAL (p,s). Exact SQL numeric data type means that the value is stored as a literal representation of the number's value.
Why are ratio scales important?
Ratio scales are very important in science. Each SQL numeric data type is used to represent all of the above values, especially intervals and ratios. You can compare character values in SQL, so one could argue that character values can also represent interval data. However, that's a topic for another article.
What are approximate numeric data types?
The approximate numeric data types are FLOAT (p), REAL, and DOUBLE PRECISION. These represent real numbers, but they are not represented as exact numbers in the database. Rather, they are an approximation of the real number because of the way that computer systems represent numbers.
What is a ratio measure?
Years, dates, and most personality measures are interval measures. Interval values are numerical and are represented as numerical in the database. Ratio values are intervals with a defined zero value. Like an interval scale, a ratio has measurable differences between values.
What are the different types of numbers?
Anyone with a background in statistics knows that there are four different scales that apply to numbers: nominal, ordinal, interval, and ratio. Unlike other data types, numerical types can represent all of these scales ...
