Implementations

source

impl PgFunc

source

pub fn to_tsquery<T>(expr: T, regconfig: Option<u32>) -> SimpleExpr where
T: Into<SimpleExpr>,

Call TO_TSQUERY function. Postgres only.

The parameter regconfig represents the OID of the text search configuration. If the value is None the argument is omitted from the query, and hence the database default used.

Examples

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

let query = Query::select()
    .expr(PgFunc::to_tsquery(Expr::val("a & b"), None))
    .to_owned();

assert_eq!(
    query.to_string(PostgresQueryBuilder),
    r#"SELECT TO_TSQUERY('a & b')"#
);

source

pub fn to_tsvector<T>(expr: T, regconfig: Option<u32>) -> SimpleExpr where
T: Into<SimpleExpr>,

Call TO_TSVECTOR function. Postgres only.

The parameter regconfig represents the OID of the text search configuration. If the value is None the argument is omitted from the query, and hence the database default used.

Examples

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

let query = Query::select()
    .expr(PgFunc::to_tsvector(Expr::val("a b"), None))
    .to_owned();

assert_eq!(
    query.to_string(PostgresQueryBuilder),
    r#"SELECT TO_TSVECTOR('a b')"#
);

source

pub fn phraseto_tsquery<T>(expr: T, regconfig: Option<u32>) -> SimpleExpr where
T: Into<SimpleExpr>,

Call PHRASE_TO_TSQUERY function. Postgres only.

The parameter regconfig represents the OID of the text search configuration. If the value is None the argument is omitted from the query, and hence the database default used.

Examples

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

let query = Query::select()
    .expr(PgFunc::phraseto_tsquery(Expr::val("a b"), None))
    .to_owned();

assert_eq!(
    query.to_string(PostgresQueryBuilder),
    r#"SELECT PHRASETO_TSQUERY('a b')"#
);

source

pub fn plainto_tsquery<T>(expr: T, regconfig: Option<u32>) -> SimpleExpr where
T: Into<SimpleExpr>,

Call PLAIN_TO_TSQUERY function. Postgres only.

The parameter regconfig represents the OID of the text search configuration. If the value is None the argument is omitted from the query, and hence the database default used.

Examples

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

let query = Query::select()
    .expr(PgFunc::plainto_tsquery(Expr::val("a b"), None))
    .to_owned();

assert_eq!(
    query.to_string(PostgresQueryBuilder),
    r#"SELECT PLAINTO_TSQUERY('a b')"#
);

source

pub fn websearch_to_tsquery<T>(expr: T, regconfig: Option<u32>) -> SimpleExpr where
T: Into<SimpleExpr>,

Call WEBSEARCH_TO_TSQUERY function. Postgres only.

The parameter regconfig represents the OID of the text search configuration. If the value is None the argument is omitted from the query, and hence the database default used.

Examples

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

let query = Query::select()
    .expr(PgFunc::websearch_to_tsquery(Expr::val("a b"), None))
    .to_owned();

assert_eq!(
    query.to_string(PostgresQueryBuilder),
    r#"SELECT WEBSEARCH_TO_TSQUERY('a b')"#
);

source

pub fn ts_rank<T>(vector: T, query: T) -> SimpleExpr where
T: Into<SimpleExpr>,

Call TS_RANK function. Postgres only.

Examples

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

let query = Query::select()
    .expr(PgFunc::ts_rank(Expr::val("a b"), Expr::val("a&b")))
    .to_owned();

assert_eq!(
    query.to_string(PostgresQueryBuilder),
    r#"SELECT TS_RANK('a b', 'a&b')"#
);

source

pub fn ts_rank_cd<T>(vector: T, query: T) -> SimpleExpr where
T: Into<SimpleExpr>,

Call TS_RANK_CD function. Postgres only.

Examples

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

let query = Query::select()
    .expr(PgFunc::ts_rank_cd(Expr::val("a b"), Expr::val("a&b")))
    .to_owned();

assert_eq!(
    query.to_string(PostgresQueryBuilder),
    r#"SELECT TS_RANK_CD('a b', 'a&b')"#
);
