pub struct Update { /* private fields */ }

Implementations

impl Update

pub fn table<S: Into<String>>(table_name: S) -> Update

Starts building a query that will update rows in the specified table.

pub fn set<S: Into<String>>(self, column_name: S, value: Value) -> Update

Adds a column value to be set by the query.

pub fn with(self, condition: Expr) -> Update

Adds a restriction on which rows should be updated by the query; only rows that match the given boolean expression will be updated. (This method would have been called where(), to better match SQL, but where is a reserved word in Rust.)

fn fmt(&self, formatter: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.
