Expand description

CharacterLengthStyle to use for unparsing

Different DBMSs uses different names for function calculating the number of characters in the string Length style uses length(x) SQLStandard style uses character_length(x)

impl PartialEq for CharacterLengthStyle

Source§

fn eq(&self, other: &CharacterLengthStyle) -> bool
