import { sql } from ‘@velo/wix-data-sql-backend’ ;

async function getAllColumns () {
try {
const results = await sql ( 'SELECT _id FROM ’ + DATABASE + ‘’ );
return results.payload.data.rows ;
} catch ( error ) {
console . error ( error );
}
}
let p = getAllColumns ()
console . log ( p );

error : TypeError: (0 , wix_data_sql_backend.sql) is not a function

What am I doing Wrong?
