What is scale in datatype
Scale is the number of digits to the right of the decimal point in a number. For example, the number 123.45 has a precision of 5 and a scale of 2 . In SQL Server, the default maximum precision of numeric and decimal data types is 38.
What does number 10 2 mean in SQL
DECIMAL(10,2) means you can have a decimal number with a maximal total precision of 10 digits. Two (2) of them after the decimal point and eight (8) before.

Numeric Data Types
| Data type | Storage |
|---|---|
| int | 4 bytes |
| bigint | 8 bytes |
| decimal(p,s) | 5-17 bytes |
| numeric(p,s) | 5-17 bytes |
What is the precision of float in SQL
The default precision for FLOAT is 53 and is equivalent to DOUBLE PRECISION. A precision of 23 or less makes FLOAT equivalent to REAL. A precision of 24 or greater makes FLOAT equivalent to DOUBLE PRECISION. If you specify a precision of 0, you get an error.
What is the scale of 1 to 5 data type
Ordinal Scale: All the data points from the ordered set falls in this category. Ex: Ratings on a 1–5 scale (5 being highest and 1 being lowest).
Is scale an ordinal data
The Ordinal scale includes statistical data type where variables are in order or rank but without a degree of difference between categories. The ordinal scale contains qualitative data; 'ordinal' meaning 'order'. It places variables in order/rank, only permitting to measure the value as higher or lower in scale.
How to generate 1 to 10 in SQL
But how to create a range in SQLBy creating a table.By using a VALUES() table constructor.By creating enough self-joins of a sufficent number of values.By using grouping sets.By just taking random records from a “large enough” table.By using the awesome PostgreSQL GENERATE_SERIES() function.By using CONNECT BY.
How to get 1 to 10 numbers in SQL
declare @i int;set @i=1;while(@i<=10)print(@i);set @i=@i+1;
What is the size of varchar
Values in VARCHAR columns are variable-length strings. The length can be specified as a value from 0 to 65,535. The effective maximum length of a VARCHAR is subject to the maximum row size (65,535 bytes, which is shared among all columns) and the character set used.
What can be the size of number data type
Data types for Access desktop databases
| Data Type | Usage | Size |
|---|---|---|
| Number | Numeric data. | 1, 2, 4, 8, or 16 bytes. |
| Date/Time | Dates and times. | 8 bytes. |
| Currency | Monetary data, stored with 4 decimal places of precision. | 8 bytes. |
| AutoNumber | Unique value generated by Access for each new record. | 4 bytes (16 bytes for ReplicationID). |
What is precision and scale for float
Decimal floating-point has distinct values for a number and the same number with various exponents (for example: 0.0, 0.00, 0.0E5, 1.0, 1.00, 1.0000). The precision is the total number of decimal digits, excluding the sign. The scale is the total number of decimal digits to the right of the decimal point.
Which is precise float or double
double has 2x more precision than float. float is a 32-bit IEEE 754 single precision Floating Point Number – 1 bit for the sign, 8 bits for the exponent, and 23* for the value. float has 7 decimal digits of precision.
Which scale is better 1 to 5 or 1 to 10
In the customer's mind, there's a difference between a rating of 6 and a rating of 7 (for example) that you can't capture on a 5-pt scale. So, on an 11-pt scale (i.e. 0 – 10), you'll get a much broader spread of the results yielding better predictive analysis.
Is scale of 1 to 5 quantitative
Interval scales – These scales have answer sets where each interval within it tells you about a deeper meaning, rather than just an ordered grouping. It provides quantitative data. For example, 1-5 is an ordered list of numbers that occur one after the other.
Is 1 to 10 scale ordinal data
An ordinal variable, is one where the order matters but not the difference between values. For example, you might ask patients to express the amount of pain they are feeling on a scale of 1 to 10. A score of 7 means more pain than a score of 5, and that is more than a score of 3.
Is scale nominal or ordinal
Nominal scale is a naming scale, where variables are simply “named” or labeled, with no specific order. Ordinal scale has all its variables in a specific order, beyond just naming them. Interval scale offers labels, order, as well as, a specific interval between each of its variable options.
How to generate a number between 1 and 10 in C
How to generate a random number in C between 1 and 10 We can generate random numbers in C between 1 and 10 using rand() and srand() functions. After passing the seed to srand(), we can calculate it by (rand() % 10) + 1.
How to print 1 to 10 in plsql
Sample Output: Enter value for first_n_number: 10 old 2: n number:= &first_n_number; new 2: n number:= 10; The first 10 numbers are: 1 2 3 4 5 6 7 8 9 10 PL/SQL procedure successfully completed.

How to get only 10 data in SQL
The following is the syntax to get the last 10 records from the table. Here, we have used LIMIT clause. SELECT * FROM ( SELECT * FROM yourTableName ORDER BY id DESC LIMIT 10 )Var1 ORDER BY id ASC; Let us now implement the above query.
What does VARCHAR 10 mean
To give you an example, CHAR(10) is a fixed-length non-Unicode string of length 10, while VARCHAR(10) is a variable-length non-Unicode string with a maximum length of 10. This means the actual length will depend upon the data.
What is the size of VARCHAR 10
Hence the size of the varchar in the disk is n+2 bytes. For Example, when we declare as varchar(10), The string will occupy 10 + 2 bytes of storage. The value of n can be from 1 to 8000 bytes. Unlike the char data type, varchar does not pad the string with blank spaces.
What data type is a number
Numeric data types are in two categories: exact and approximate. Exact types include integer and decimal data types. Approximate types include floating point data types.
What data type is used for numbers
Numeric Data Types
There are several different ones. An integer is a numeric value without a decimal. Integers are whole numbers and can be positive or negative. Sometimes a distinction is made between short and long integers, referring to how much data storage is used for the number.
What is precision scales
A precision scale is a weighing instrument with high sensibility, designed, precisely, to measure the mass of solids and liquids with a high level of precision. Generally, this type of scales has less capicity and are used to weigh smaller masses, when compared to the scales we use daily.
