I always created the strings with the quotation marks, like this:
local minhaString = "Eu sou uma string"
I downloaded a source to give a studied language and I came across the following way to create a string :
local query = [[
SELECT *
FROM 'pointshop_data'
WHERE uniqueid = '%s'
]]
What is the advantage / difference in using [[ / ]] ? How do I pass the %s ? Parameter
The bracketed form is brute, it essentially does not work with special characters and considers "everything" as text, including when it skips the line. It's like using the @ of C # .
To use arguments to be inserted into the text you must use the string.format() function.
The main difference is that strings created with quotation marks accept escape sequences such as \n and \t . Strings created with brackets do not interpret any escape sequences.
See the manual .
% w / w in your example indicates that the string is likely to be used as a format in %s . Other than that, there is no special meaning.
