Parser

Parse a SQL schema dump.

Create the lexer for one input.

Create the state of one parse.

Read the statement's represented facts, leaving any unread remainder to be skipped.

Read a column type.

Record that a statement the dialect does not read may change relations without naming them, unless it only changes rows.

Row changes can still run server-side code, such as triggers, whose effects are outside the impact.

Read an identifier.

Read an optionally schema-qualified name.

Read the name of a table or view, which belongs to the default schema when unqualified.

Read a parenthesized list of identifiers.

Read a collation name, keeping its qualification and quoting as written.

Read a parenthesized group, returning its source text with the brackets.

Read an expression that ends before a clause keyword or the end of its list entry.

Determine whether the current word begins one of the given clauses rather than naming a schema.

Read a string literal that forms a complete value, or return null without consuming anything.

Determine whether the current list entry, such as a column definition, has ended.

Skip the rest of the current list entry.

Read the parenthesized columns and constraints of a table.

Determine whether a table body entry is a constraint rather than a column.

Read the name given by a CONSTRAINT keyword, if any.

Read a table constraint, keeping an unsupported one as a table issue.

Read a table constraint, or a column constraint on the given column, returning false when it is not supported.

Read a column definition into the table.

Read one column clause, returning false when it is not supported.

Read a generated column's parenthesized expression and kind, which is virtual unless stored.

Make the columns of a primary key non-null on a table.

Find a table's column by the name a key or constraint gives it.

Read a parenthesized list of index keys.

Read an index key without confusing an expression with a column name.

Read a foreign key's match mode and referential actions, which can come in any order.

Read a referential action.

Read a view from its name, without inferring the types its query produces, and return its name.

Determine whether a name belongs to the session's temporary schema.

Determine whether a known relation already has the given name.

Read a view query, excluding a trailing view option.

Determine whether a WITH clause is the view's trailing check option.

Freeze the parsed definitions into a schema.

Freeze a table after resolving foreign keys that omit their referenced columns.

Get the columns a foreign key references, which default to the referenced table's primary key, or null when they cannot be resolved.

Freeze a column.
