Required Methods§

source

fn begin_transaction( &mut self, db_handle: &mut Self::DbHandle, confs: TransactionConfiguration ) -> Result<Self::TrHandle, FbError>

Start a new transaction, with the specified transaction parameter buffer

source

fn transaction_operation( &mut self, tr_handle: &mut Self::TrHandle, op: TrOp ) -> Result<(), FbError>

Commit / Rollback a transaction

source

fn exec_immediate( &mut self, db_handle: &mut Self::DbHandle, tr_handle: &mut Self::TrHandle, dialect: Dialect, sql: &str ) -> Result<(), FbError>

Execute a sql immediately, without returning rows

source

fn prepare_statement( &mut self, db_handle: &mut Self::DbHandle, tr_handle: &mut Self::TrHandle, dialect: Dialect, sql: &str ) -> Result<(StmtType, Self::StmtHandle), FbError>

Allocate and prepare a statement Returns the statement type and handle

source

fn free_statement( &mut self, stmt_handle: &mut Self::StmtHandle, op: FreeStmtOp ) -> Result<(), FbError>

Closes or drops a statement

source

fn execute( &mut self, db_handle: &mut Self::DbHandle, tr_handle: &mut Self::TrHandle, stmt_handle: &mut Self::StmtHandle, params: Vec<SqlType> ) -> Result<usize, FbError>

Execute the prepared statement with parameters and returns the affected rows count

source

fn execute2( &mut self, db_handle: &mut Self::DbHandle, tr_handle: &mut Self::TrHandle, stmt_handle: &mut Self::StmtHandle, params: Vec<SqlType> ) -> Result<Vec<Column>, FbError>

Execute the prepared statement with input and output parameters.

The output parameters will be returned as in the Result

source

fn fetch( &mut self, db_handle: &mut Self::DbHandle, tr_handle: &mut Self::TrHandle, stmt_handle: &mut Self::StmtHandle ) -> Result<Option<Vec<Column>>, FbError>

Fetch rows from the executed statement, coercing the types according to the provided blr
