Struct Config 

pub struct Config {
    pub database_url_var: Option<String>,
}

Configuration shared by multiple components.

Fields

database_url_var: Option<String>

Override the database URL environment variable.

This is used by both the macros and sqlx-cli.

Case-sensitive. Defaults to DATABASE_URL.

Example: Multi-Database Project

You can use multiple databases in the same project by breaking it up into multiple crates, then using a different environment variable for each.

For example, with two crates in the workspace named foo and bar:

foo/sqlx.toml

[common]
database-url-var = "FOO_DATABASE_URL"

bar/sqlx.toml

[common]
database-url-var = "BAR_DATABASE_URL"

.env

FOO_DATABASE_URL=postgres://postgres@localhost:5432/foo
BAR_DATABASE_URL=postgres://postgres@localhost:5432/bar

The query macros used in foo will use FOO_DATABASE_URL, and the ones used in bar will use BAR_DATABASE_URL.
