Expand description

Defines a table for SQLite

Fields§

§name: String

The table name

§foreign_keys: Vec<ForeignKeysInfo>

A list of foreign keys in the table

§indexes: Vec<IndexInfo>

A list of the indexes in the table

§constraints: Vec<IndexInfo>

A list of UNIQUE and PRIMARY KEY constraints on the table

§columns: Vec<ColumnInfo>

A list of all the columns and their types

§auto_increment: bool

Whether the primary key should autoincrement

Implementations§

§

impl TableDef

pub async fn pk_is_autoincrement( &mut self, conn: &impl Connection, ) -> DiscoveryResult<&mut Self>

Check if the primary key in the table is set to autoincrement as a result of using query `SELECT COUNT(*) from sqlite_sequence where name = ‘table_name’;

pub async fn get_constraints( &mut self, conn: &impl Connection, ) -> DiscoveryResult<()>

Get a list of most of the UNIQUE and PRIMARY KEY constraints on the table. These are implemented by indexes in most cases. These indexes have type “u” or “pk”. Note that this does not get the column name mapped by the index. To get the column name mapped by the index, the self.get_single_indexinfo method is invoked

pub async fn get_indexes( &mut self, conn: &impl Connection, ) -> DiscoveryResult<()>

Get a list of all the indexes in the table. Note that this does not get the column name mapped by the index. To get the column name mapped by the index, the self.get_single_indexinfo method is invoked

pub async fn get_foreign_keys( &mut self, conn: &impl Connection, ) -> DiscoveryResult<&mut Self>

Get a list of all the foreign keys in the table

pub async fn get_column_info( &mut self, conn: &impl Connection, ) -> DiscoveryResult<&TableDef>

Get a list of all the columns in the table mapped as ColumnInfo

pub fn write(&self) -> TableCreateStatement
