How do I find the default character set in MySQL?

To see the default character set and collation for a given database, use these statements: USE db_name; SELECT @@character_set_database, @@collation_database; Alternatively, to display the values without changing the default database: SELECT DEFAULT_CHARACTER_SET_NAME, DEFAULT_COLLATION_NAME FROM INFORMATION_SCHEMA.

Is UTF-8 and ASCII same?

UTF-8 encodes Unicode characters into a sequence of 8-bit bytes. … Each 8-bit extension to ASCII differs from the rest. For characters represented by the 7-bit ASCII character codes, the UTF-8 representation is exactly equivalent to ASCII, allowing transparent round trip migration.

What is the difference between base64 and UTF-8?

The UTF-8 format refers to the UTF-8 character encoding for Unicode. Unlike hex and base64, which are binary-to-text encodings, UTF-8 is a text-to-binary encoding. This means that conversion from string to binary always succeeds, but conversion from binary to string can fail.

What is a default database?

Within a stored routine, the default database is the database that the routine is associated with, which is not necessarily the same as the database that is the default in the calling context. SCHEMA() is a synonym for DATABASE().

What is the difference between utf8_general_ci and utf8_unicode_ci?

Key differences

utf8mb4_unicode_ci is based on the official Unicode rules for universal sorting and comparison, which sorts accurately in a wide range of languages. utf8mb4_general_ci is a simplified set of sorting rules which aims to do as well as it can while taking many short-cuts designed to improve speed.

What is UTF full form?

Stands for “Unicode Transformation Format.” UTF refers to several types of Unicode character encodings, including UTF-7, UTF-8, UTF-16, and UTF-32. UTF-7 – uses 7 bits for each character. It was designed to represent ASCII characters in email messages that required Unicode encoding.

What is charset and collation in MySQL?

A character set is a set of symbols and encodings. A collation is a set of rules for comparing characters in a character set. … The collation is a set of rules (only one rule in this case): “compare the encodings.” We call this simplest of all possible collations a binary collation.
