Struct sea_query::index::IndexDropStatement

pub struct IndexDropStatement { /* private fields */ }

Drop an index for an existing table

Examples

use sea_query::{tests_cfg::*, *};

let index = Index::drop()
    .name("idx-glyph-aspect")
    .table(Glyph::Table)
    .to_owned();

assert_eq!(
    index.to_string(MysqlQueryBuilder),
    r#"DROP INDEX `idx-glyph-aspect` ON `glyph`"#
);
assert_eq!(
    index.to_string(PostgresQueryBuilder),
    r#"DROP INDEX "idx-glyph-aspect""#
);
assert_eq!(
    index.to_string(SqliteQueryBuilder),
    r#"DROP INDEX "idx-glyph-aspect""#
);
