Implementations

impl CreateTable

pub fn new(name: TableName, columns: Vec<ColumnDefinition>) -> Self

new instance with column definitions

pub fn name(&self) -> &TableName

get table name

pub fn get_column_def( &self, column_name: &ColumnName, ) -> Option<&ColumnDefinition>

get column definition by column name

pub fn get_column_def_with_skip_count( &self, column_name: &ColumnName, skip_count: usize, ) -> Option<&ColumnDefinition>

Look up a column definition by original column name, ignoring the first skip_count columns.

This is used to implement PostgreSQL’s behavior for a table alias with a column alias list:

SELECT ... FROM users AS u(id, name);

When a column alias list is present, the original names of the first N columns (N = the length of the alias list) are not visible through that alias. Only the alias names are visible for those columns. Columns after the first N keep their original names.

For example, if users has at least two columns and the 1st column is named user_id, then u.user_id is not accessible when skip_count >= 1 (e.g. u(id, name) makes skip_count = 2). However, columns after the first skip_count columns are still accessible by their original names.

pub fn get_column_at(&self, column_index: usize) -> Option<&ColumnDefinition>

get column definition by index

pub fn has_column(&self, column: &ColumnName) -> bool

check column existing

pub fn apply_alter( &mut self, alter_table: &AlterTable, ) -> Result<Vec<ImplicitChange>, AnalysisError>

apply alter table statement

pub fn primary_key_columns(&self) -> Vec<&ColumnName>

get primary key column names
