What is Tinyint data type?

A 1-byte integer data type used in CREATE TABLE and ALTER TABLE statements.

What is the difference between Int and Smallint?

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. They take up little space (2 bytes per value for SMALLINT and 4 bytes per value for INTEGER).

Is monetary data type in SQL Server?

Currency or monetary data does not need to be enclosed in single quotation marks ( ‘ ). It is important to remember that while you can specify monetary values preceded by a currency symbol, SQL Server does not store any currency information associated with the symbol, it only stores the numeric value.

What is data type for MONEY?

Unlike the DECIMAL data type, the MONEY data type is always treated as a fixed-point decimal number. The database server defines the data type MONEY(p) as DECIMAL(p,2). If the precision and scale are not specified, the database server defines a MONEY column as DECIMAL(16,2).

What data type is MONEY SQL?

The money data type is an abstract data type. Money values are stored significant to two decimal places. These values are rounded to their amounts in dollars and cents or other currency units on input and output, and arithmetic operations on the money data type retain two-decimal-place precision.

VARCHAR is a variable length string data type, so it holds only the characters you assign to it. VARCHAR takes up 1 byte per character, + 2 bytes to hold length information. For example, if you set a VARCHAR(100) data type = ‘Jen’, then it would take up 3 bytes (for J, E, and N) plus 2 bytes, or 5 bytes in all.

What does varchar 100 mean?

varchar(100) means your variable FirstName can hold a value uuto hunder character, if the it is for 1000 it holds thousand characters. but unused characters do not consume storage. The storage will be n*1 byte+1= n1 bytes, in your case 100 = 100*1 byte +2 bytes=102 bytes.

What is the maximum integer in SQL Server?

What is int limit in SQL Server?

MAXINT or INT_MAX is the highest number that can be represented by a given integer data type. In SQL Server this number for the INT data type is 2,147,483,647.

What is the datatype of null in SQL Server?

Most, if not all, datatypes in SQL Server can be NULL; it’s just the representation of the absence of a value. SQL Server stores a “NULL Bitmap” for each row that tells it which columns are . If you were using NULL in a SELECT statement (example below) it defaults to a datatype of int. The data type of the column [EmptyColumn] will be int.
