[−][src]Struct odbc_api::parameter::WithDataType
Annotates an instance of an inner type with an SQL Data type in order to indicate how it should be bound as a parameter to an SQL Statement.
Example
use odbc_api::{Environment, parameter::WithDataType, DataType}; let env = unsafe { Environment::new()? }; let mut conn = env.connect("YourDatabase", "SA", "<YourStrong@Passw0rd>")?; // Bind year as VARCHAR(4) rather than integer. let year = WithDataType{ value: 1980, data_type: DataType::Varchar {length: 4} }; if let Some(cursor) = conn.execute("SELECT year, name FROM Birthdays WHERE year > ?;", year)? { // Use cursor to process query results. }
