In the above tables, Collations are ending with _ci, the ci here stands for Case-insensitive.There is a MySQL statement to know about the default collations of character sets as follows: SHOW CHARACTER SET įetching Collations using WHERE statement For example, to use the utf8 Unicode character set, use this statement after establishing connecting to the server : If you want the client program to communicate with the server using a Character-set different from the default, you’ll need to highlight which one of the character set you are using. Character-set not only affects data storage but also affects the communication medium between client programs and the MySQL server.We explicitly apply the technique of Collation(Compare there corresponding encoding) to our Character-set. So, how we have able to perform this comparison, just because of Collation. We have an easier method to do this, just a moment ago we have assigned a distinct value to some alphabets like encoding of A is 1, for B it is 2 similarly encoding for a and b is 5 and 6. So, for symbol A encoding is 1, for B encoding is 2, for C encoding is 3, and so on. Suppose, we have some alphabet with A,B,C,D,a,b,c,d.We can highlight character sets at the server, database, table, and column level. A Character-set allows us to store data through a variety of character sets and do comparisons according to a variety of collations. A collation is a set of rules for comparing characters in a character set. A character set is a set of specific symbols and encoding techniques.Introduction of 3-Tier Architecture in DBMS | Set 2.Difference between Primary key and Unique key.Difference between DELETE, DROP and TRUNCATE.Types of Keys in Relational Model (Candidate, Super, Primary, Alternate and Foreign).Difference between Clustered and Non-clustered index.
