What is real data type in SQL?

What is CLOB and BLOB in SQL?
The full form of Blob is a Binary Large Object. The full form of Clob is Character Large Object. This is used to store large binary data. This is used to store large textual data. This stores values in the form of binary streams.
What can be stored in CLOB?
A CLOB (character large object) value can be up to 2,147,483,647 characters long. A CLOB is used to store unicode character-based data, such as large documents in any character set.
Are float and real the same?
Real is a Single Precision Floating Point number, while Float is a Double Precision Floating Point number. The Floating point numbers can store very large or very small numbers than decimal numbers. But this trade-off comes at the cost of precision.
What is :: float in SQL?
Float is an approximate number data type used to store a floating-point number. float (n) – n is the number of bits that are used to store the mantissa in scientific notation. Range of values: – 1.79E+308 to -2.23E-308, 0 and 2.23E-308 to 1.79E+308. Storage size: 4 Bytes if n = 1-9 and 8 Bytes if n = 25-53 – default = …
What is the use of BLOB in SQL?

BLOB data type is generally used to store large files such as images, media files such as video and audio clips in the database.
What is the difference between CLOB and VARCHAR?
The difference between the 2 types is that in VARCHAR2 you have to specify the length of the stored string and that length is limited to 4000 characters while CLOB can store up to 128 terabytes of character data in the database.

What is LOB and CLOB?
LOB stands for Large Object and it’s a data type that are for storing large objects. BLOB stands for Binary Large Object and is in binary format- and it’s not uncommon to see images stored that way. CLOB stands for Character Large Object and allows us to store string data in database character set format.
