A pure rust SQL driver for SAP HANA(TM).
## Usage
Add hdbconnect to the dependencies section in your project's `Cargo.toml`:
```toml
[dependencies]
hdbconnect = "0.22"
```
Assume you have a HANA accessible at port `39013` on host `hxehost`,
and you can log on to it as user `HORST` with password `SeCrEt`.
Then a first simple test might look like this:
```rust
use hdbconnect::{Connection, HdbResult};
pub fn main() -> HdbResult<()> {
// Get a connection
let url = "hdbsql://HORST:SeCrEt@hxehost:39013";
let mut connection = Connection::new(url)?;
// Cleanup if necessary, and set up a test table
connection.multiple_statements_ignore_err(vec![
"drop table FOO_SQUARE"
]);
connection.multiple_statements(vec![
"create table FOO_SQUARE ( f1 INT primary key, f2 INT)",
])?;
// Insert some test data
let mut insert_stmt = connection.prepare(
"insert into FOO_SQUARE (f1, f2) values(?,?)"
)?;
for i in 0..100 {
insert_stmt.add_batch(&(i, i * i))?;
}
insert_stmt.execute_batch()?;
// Read the table data directly into a rust data structure
let stmt = "select * from FOO_SQUARE order by f1 asc";
let n_square: Vec<(i32, u64)> =
connection.query(stmt)?.try_into()?;
// Verify ...
for (idx, (n, square)) in n_square.into_iter().enumerate() {
assert_eq!(idx as i32, n);
assert_eq!((idx * idx) as u64, square);
}
Ok(())
}
```
