Struct Statement 

pub struct Statement { /* private fields */ }

A parsed SQL statement ready for execution

Implementations

impl Statement

pub fn new(sql: impl Into<String>) -> Self

Create a new statement from SQL text

pub fn sql(&self) -> &str

Get the SQL text

pub fn sql_bytes(&self) -> &[u8]

Get the SQL bytes

pub fn statement_type(&self) -> StatementType

Get the statement type

pub fn is_query(&self) -> bool

Check if this is a query (SELECT)

pub fn is_dml(&self) -> bool

Check if this is a DML statement

pub fn is_ddl(&self) -> bool

Check if this is a DDL statement

pub fn is_plsql(&self) -> bool

Check if this is a PL/SQL block

pub fn is_returning(&self) -> bool

Check if this is a RETURNING statement

pub fn cursor_id(&self) -> u16

Get the cursor ID

pub fn set_cursor_id(&mut self, id: u16)

Set the cursor ID

pub fn bind_info(&self) -> &[BindInfo]

Get the bind parameters

pub fn columns(&self) -> &[ColumnInfo]

Get the column metadata

pub fn set_columns(&mut self, columns: Vec<ColumnInfo>)

Set column metadata (from server describe)

pub fn column_count(&self) -> usize

Get the number of columns

pub fn executed(&self) -> bool

Check if the statement has been executed

pub fn set_executed(&mut self, executed: bool)

Mark the statement as executed

pub fn binds_changed(&self) -> bool

Check if binds have changed

pub fn set_binds_changed(&mut self, changed: bool)

Set binds changed flag

pub fn requires_define(&self) -> bool

Check if column define is required

pub fn set_requires_define(&mut self, required: bool)

Set requires define flag

pub fn no_prefetch(&self) -> bool

Check if prefetch should be disabled

pub fn set_no_prefetch(&mut self, no_prefetch: bool)

Set no prefetch flag

pub fn set_statement_type(&mut self, stmt_type: StatementType)

Set the statement type (useful for scroll operations that reuse cursors)

pub fn clear(&mut self)

Clear statement state for re-execution

pub fn clone_for_reuse(&self) -> Self

Clone statement for cache reuse, preserving cursor_id and metadata

This creates a copy of the statement that can be executed with new bind values while reusing the server-side cursor. The cursor_id, column metadata, and bind info are preserved.

Trait Implementations

impl Clone for Statement

fn clone(&self) -> Statement

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Statement

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
