Implementations§

§

impl TableCreateStatement

pub fn new() -> TableCreateStatement

Construct create table statement

pub fn if_not_exists(&mut self) -> &mut TableCreateStatement

Create table if table not exists

pub fn table<T>(&mut self, table: T) -> &mut TableCreateStatementwhere T: IntoTableRef,

Set table name

pub fn col(&mut self, column: &mut ColumnDef) -> &mut TableCreateStatement

Add a new table column

pub fn check(&mut self, value: SimpleExpr) -> &mut TableCreateStatement

pub fn index( &mut self, index: &mut IndexCreateStatement ) -> &mut TableCreateStatement

Add an index. MySQL only.

Examples

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

assert_eq!(
    Table::create()
        .table(Glyph::Table)
        .col(ColumnDef::new(Glyph::Id).integer().not_null())
        .index(Index::create().unique().name("idx-glyph-id").col(Glyph::Id))
        .to_string(MysqlQueryBuilder),
    [
        "CREATE TABLE `glyph` (",
        "`id` int NOT NULL,",
        "UNIQUE KEY `idx-glyph-id` (`id`)",
        ")",
    ]
    .join(" ")
);

pub fn primary_key( &mut self, index: &mut IndexCreateStatement ) -> &mut TableCreateStatement

Add an primary key.

Examples

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

let mut statement = Table::create();
statement
    .table(Glyph::Table)
    .col(ColumnDef::new(Glyph::Id).integer().not_null())
    .col(ColumnDef::new(Glyph::Image).string().not_null())
    .primary_key(Index::create().col(Glyph::Id).col(Glyph::Image));
assert_eq!(
    statement.to_string(MysqlQueryBuilder),
    [
        "CREATE TABLE `glyph` (",
        "`id` int NOT NULL,",
        "`image` varchar(255) NOT NULL,",
        "PRIMARY KEY (`id`, `image`)",
        ")",
    ]
    .join(" ")
);
assert_eq!(
    statement.to_string(PostgresQueryBuilder),
    [
        "CREATE TABLE \"glyph\" (",
        "\"id\" integer NOT NULL,",
        "\"image\" varchar NOT NULL,",
        "PRIMARY KEY (\"id\", \"image\")",
        ")",
    ]
    .join(" ")
);
assert_eq!(
    statement.to_string(SqliteQueryBuilder),
    [
        r#"CREATE TABLE "glyph" ("#,
        r#""id" integer NOT NULL,"#,
        r#""image" text NOT NULL,"#,
        r#"PRIMARY KEY ("id", "image")"#,
        r#")"#,
    ]
    .join(" ")
);

pub fn foreign_key( &mut self, foreign_key: &mut ForeignKeyCreateStatement ) -> &mut TableCreateStatement

Add a foreign key

pub fn engine<T>(&mut self, string: T) -> &mut TableCreateStatementwhere T: Into<String>,

Set database engine. MySQL only.

pub fn collate<T>(&mut self, string: T) -> &mut TableCreateStatementwhere T: Into<String>,

Set database collate. MySQL only.

pub fn character_set<T>(&mut self, name: T) -> &mut TableCreateStatementwhere T: Into<String>,

Set database character set. MySQL only.

pub fn get_table_name(&self) -> Option<&TableRef>

pub fn get_columns(&self) -> &Vec<ColumnDef, Global>

pub fn get_foreign_key_create_stmts( &self ) -> &Vec<ForeignKeyCreateStatement, Global>

pub fn get_indexes(&self) -> &Vec<IndexCreateStatement, Global>

pub fn extra<T>(&mut self, extra: T) -> &mut TableCreateStatementwhere T: Into<String>,

Rewriting extra param. You should take care self about concat extra params. Add extra after options. Example for PostgresSQL Citus extension:

use sea_query::{tests_cfg::*, *};
let table = Table::create()
    .table(Char::Table)
    .col(
        ColumnDef::new(Char::Id)
            .uuid()
            .extra("DEFAULT uuid_generate_v4()")
            .primary_key()
            .not_null(),
    )
    .col(
        ColumnDef::new(Char::CreatedAt)
            .timestamp_with_time_zone()
            .extra("DEFAULT NOW()")
            .not_null(),
    )
    .col(ColumnDef::new(Char::UserData).json_binary().not_null())
    .extra("USING columnar")
    .to_owned();
assert_eq!(
    table.to_string(PostgresQueryBuilder),
    [
        r#"CREATE TABLE "character" ("#,
        r#""id" uuid DEFAULT uuid_generate_v4() PRIMARY KEY NOT NULL,"#,
        r#""created_at" timestamp with time zone DEFAULT NOW() NOT NULL,"#,
        r#""user_data" jsonb NOT NULL"#,
        r#") USING columnar"#,
    ]
    .join(" ")
);
