[Communication] SQL statement link and fuzzy query usage

[Copy link]
Posted on 11/17/2014 10:39:28 PM | | |
Like is generally used with the % symbol to achieve fuzzy query functions:
% can represent any string
Take an example:
a%b%cdefg% description - any number of characters can be replaced with any number of characters at the % sign
List one or two strings that can be matched:
[a] mkfjgsjrg [b] keksrfkl [cdefg]dfgreg (outside the square brackets is a string with % placeholders)

Where to use:
After where, in the form of a condition, the output is restricted, such as:
select * from AAA where AA1 like '123%'
