Struct BulkColumn 

pub struct BulkColumn {
    pub name: String,
    pub sql_type: String,
    pub nullable: bool,
    pub ordinal: usize,
    /* private fields */
}

Column definition for bulk insert.

Fields

name: String

Column name.

sql_type: String

SQL Server type (e.g., “INT”, “NVARCHAR(100)”).

nullable: bool

Whether the column allows NULL values.

ordinal: usize

Column ordinal (0-based).

Implementations

impl BulkColumn

pub fn new<S: Into<String>>( name: S, sql_type: S, ordinal: usize, ) -> Result<Self, TypeError>

Create a new bulk column definition.

Errors

Returns TypeError::UnsupportedType when sql_type names a deprecated large object type (TEXT, NTEXT, IMAGE). Use VARCHAR(MAX) / NVARCHAR(MAX) / VARBINARY(MAX) instead — Microsoft deprecated TEXT / NTEXT / IMAGE in SQL Server 2005 and recommends the MAX types for all new development.

pub fn with_nullable(self, nullable: bool) -> Self

Set whether this column allows NULL values.

pub fn with_collation(self, collation: Collation) -> Self

Set the collation used for VARCHAR/CHAR columns.

Required when Client::bulk_insert_without_schema_discovery targets VARCHAR columns on a server whose default collation is not Latin1_General_CI_AS and the target column uses a different code page. Ignored for NVARCHAR/NCHAR columns (always UTF-16).

Trait Implementations

impl Clone for BulkColumn

fn clone(&self) -> BulkColumn

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BulkColumn

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

Formats the value using the given formatter.
