pub struct SelectBuilder { /* private fields */ }

Implementations

impl SelectBuilder

pub fn new(from: &str) -> Self

Create a new select query for a given table

Examples

use postgres_querybuilder::SelectBuilder;

let mut builder = SelectBuilder::new("users");

pub fn select(&mut self, column: &str) -> &mut Self

Add a column to select

Examples

use postgres_querybuilder::SelectBuilder;
use postgres_querybuilder::prelude::QueryBuilder;

let mut builder = SelectBuilder::new("users");
builder.select("id");
builder.select("email");

assert_eq!(builder.get_query(), "SELECT id, email FROM users");

pub fn add_where_raw(&mut self, raw: String) -> &mut Self

Add a raw where condition

Examples

use postgres_querybuilder::SelectBuilder;
use postgres_querybuilder::prelude::QueryBuilder;

let mut builder = SelectBuilder::new("users");
builder.add_where_raw("something IS NULL".into());

assert_eq!(builder.get_query(), "SELECT * FROM users WHERE something IS NULL");
