What is the range of values of integer data type?
-2,147,483,647 to 2,147,483,647
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.
Is integer in Teradata?
REGEXP_SIMILAR Regular Expression To Check Integer Type This is one of the fastest method to check if a string is integer. For example, following regular expression checks if string is integer. Just like TO_NUMBER function, you can use the REGEXP_SIMILAR function in the WHERE clause to filter out non integer values.
What is the range of number data type?
Numeric Data Types
| Data Type | Data Value |
|---|---|
| SHORTDECIMAL | A decimal number with up to 7 significant digits in the range of -(10**38) to +(10**38). |
| NUMBER | A decimal number with up to 38 significant digits in the range of -(10**125) to +(10**125). |
What integer data type has a range of to 127?
byte data type
The byte data type is an 8-bit signed Java primitive integer data type. Its range is -128 to 127 (-27 to 27 – 1). This is the smallest integer data type available in Java. Unlike int and long literals, there are no byte literals.
What is the size of integer data type?
Data Types and Sizes
| Type Name | 32–bit Size | 64–bit Size |
|---|---|---|
| short | 2 bytes | 2 bytes |
| int | 4 bytes | 4 bytes |
| long | 4 bytes | 8 bytes |
| long long | 8 bytes | 8 bytes |
Which is the largest integer range?
2,147,483,647
The number 2,147,483,647 (or hexadecimal 7FFFFFFF16) is the maximum positive value for a 32-bit signed binary integer in computing. It is therefore the maximum value for variables declared as integers (e.g., as int ) in many programming languages.
How many digits can integer hold in Teradata?
Teradata – Data Types

Is numeric SQL Teradata?
The relational databases such as SQL-Server supports isnumeric functions. But, as of now Teradata does not support is numeric function. You have to use an alternate methods to check if a string or value is numeric type in Teratadat.
What is a double vs float?
A Double and Float are both used to represent decimal numbers, but they do so in slightly different ways. For Float this means that it only has four decimal places while Double still has twelve.
What is the smallest data type?
byte
The smallest data type is a byte, which is 8 bits. Each bit can be a 0 or 1. The simplest data type is an unsigned char. The unsigned char type is one byte long, and the number it repre- sents are just the 8 bits in base 2.
What is the size of float data type?
4 bytes
Windows 64-bit applications
| Name | Length |
|---|---|
| float | 4 bytes |
| double | 8 bytes |
| long double | 8 bytes |
| pointer | 8 bytes Note that all pointers are 8 bytes. |
How can I define different sizes of an integer?
What is required by standard:
- char is the smallest memory unit and has at least 8 bits – all other types have a size that is a multiple of the size of char.
- short has at least 16 bits.
- int is at least as large as short and has at least 16 bits.
- long is at least as large as int and has as least 32 bits.
Is there any way to change datatype in Teradata?
The options for changing or modifying the length of a datatype are limited in Teradata. However, we can use the below code for changing the length only for VARCHAR types. To modify a column type, length or format, we can use ADD function in Teradata ALTER TABLE Table_Name ADD Existing_Column_Name New_Data_Type(New_Length)
What are the different temporary tables in Teradata?
