Usually we will use SQL queries like below, we will pass params with predifined number $1
queryRunner.query('SELECT * FROM sample_data WHERE code IN ($1)', ['1'])
But I want to pass multiple params without predifined $1. Any way to resolve this?
queryRunner.query('SELECT * FROM sample_data WHERE code IN ($$)', ['1','2','3'])
One approach dynamically builds the IN clause based on the expected number of parameters. Consider:
var params = ['1','2','3'];
var inClause = '?' + ', ?'.repeat(params.length - 1);
var sql = 'SELECT * FROM sample_data WHERE code IN (' + inClause + ')';
console.log(sql);Once we have a statement with the right number of placeholders, we can simply bind the collection or array with no trouble.
