Transaction Parser

Implementations§

Source§

impl TransactionParser

Source

pub fn new() -> Self

Source

pub fn parse_begin_transaction( &mut self, ctx: &mut ParseContext<'_>, ) -> Result<Stmt, ParseError>

Parse BEGIN TRANSACTION statement

Grammar: BEGIN [TRANSACTION] [READ ONLY | READ WRITE]

Source

pub fn parse_commit_transaction( &mut self, ctx: &mut ParseContext<'_>, ) -> Result<Stmt, ParseError>

Parse COMMIT TRANSACTION statement

Source

pub fn parse_rollback_transaction( &mut self, ctx: &mut ParseContext<'_>, ) -> Result<Stmt, ParseError>

Parse ROLLBACK TRANSACTION statement

Grammar: ROLLBACK [TRANSACTION] [TO [SAVEPOINT] <savepoint-name>]. The SAVEPOINT keyword is optional; a savepoint literally named savepoint is unreachable because the name position never accepts the reserved word (see expect_identifier).

Source

pub fn parse_savepoint_statement( &mut self, ctx: &mut ParseContext<'_>, ) -> Result<Stmt, ParseError>

Parse SAVEPOINT statement

Grammar: SAVEPOINT <savepoint-name>

Source

pub fn parse_release_savepoint( &mut self, ctx: &mut ParseContext<'_>, ) -> Result<Stmt, ParseError>

Parse RELEASE SAVEPOINT statement

Grammar: RELEASE SAVEPOINT <savepoint-name>
