Struct DropDatabaseStatement 

pub struct DropDatabaseStatement { /* private fields */ }

DROP DATABASE statement builder

This struct provides a fluent API for constructing DROP DATABASE queries. It supports both basic DROP DATABASE and PostgreSQL-specific options.

Examples

use reinhardt_query::prelude::*;

// DROP DATABASE mydb
let query = Query::drop_database()
    .name("mydb");

// DROP DATABASE IF EXISTS mydb
let query = Query::drop_database()
    .name("mydb")
    .if_exists();

// DROP DATABASE mydb WITH (FORCE) (PostgreSQL)
let query = Query::drop_database()
    .name("mydb")
    .force();

Implementations

impl DropDatabaseStatement

pub fn new() -> Self

Create a new DROP DATABASE statement

Examples

use reinhardt_query::prelude::*;

let query = Query::drop_database();

pub fn take(&mut self) -> Self

Take the ownership of data in the current DropDatabaseStatement

pub fn name<N>(&mut self, name: N) -> &mut Self

where N: IntoIden,

Set the database name

Examples

use reinhardt_query::prelude::*;

let query = Query::drop_database()
    .name("mydb");

pub fn if_exists(&mut self) -> &mut Self

Add IF EXISTS clause

Examples

use reinhardt_query::prelude::*;

let query = Query::drop_database()
    .name("mydb")
    .if_exists();

pub fn force(&mut self) -> &mut Self

Add FORCE option (PostgreSQL 13+)

Forces termination of all connections to the database before dropping it.

Examples

use reinhardt_query::prelude::*;

let query = Query::drop_database()
    .name("mydb")
    .force();

pub fn cascade(&mut self) -> &mut Self

Add CASCADE option

Automatically drops objects contained in the database.

Examples

use reinhardt_query::prelude::*;

let query = Query::drop_database()
    .name("mydb")
    .cascade();
