Struct DropTableStatement 

pub struct DropTableStatement { /* private fields */ }

Available on crate feature database and non-WebAssembly only.

DROP TABLE statement builder

This struct provides a fluent API for constructing DROP TABLE queries.

Examples

use reinhardt_query::prelude::*;

let query = Query::drop_table()
    .table("users")
    .if_exists();

Implementations

impl DropTableStatement

pub fn new() -> DropTableStatement

Create a new DROP TABLE statement

pub fn take(&mut self) -> DropTableStatement

Take the ownership of data in the current DropTableStatement

pub fn table<T>(&mut self, tbl: T) -> &mut DropTableStatement

where T: IntoTableRef,

Set the table to drop

Examples

use reinhardt_query::prelude::*;

let query = Query::drop_table()
    .table("users");

pub fn tables<I, T>(&mut self, tbls: I) -> &mut DropTableStatement

where I: IntoIterator<Item = T>, T: IntoTableRef,

Set multiple tables to drop

Examples

use reinhardt_query::prelude::*;

let query = Query::drop_table()
    .tables(vec!["users", "posts", "comments"]);

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

Add IF EXISTS clause

Examples

use reinhardt_query::prelude::*;

let query = Query::drop_table()
    .table("users")
    .if_exists();

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

Add CASCADE clause

This option automatically drops dependent objects. Supported by PostgreSQL.

Examples

use reinhardt_query::prelude::*;

let query = Query::drop_table()
    .table("users")
    .cascade();

pub fn restrict(&mut self) -> &mut DropTableStatement

Add RESTRICT clause

This option prevents dropping if there are dependent objects (default behavior). Supported by PostgreSQL.

Examples

use reinhardt_query::prelude::*;

let query = Query::drop_table()
    .table("users")
    .restrict();
