Correct Nodejs mssql parameterized LIKE query syntax - sql-server

Question

Using Nodejs and mssql package for SQL Server, I understand normal SELECT query with parameters:
aVar = "somestring"; // used as example, the real input is from a web form
request = new sql.Request(conn)
.input('aParam', sql.NVarChar(200), aVar);
q = "SELECT * FROM myTable WHERE theColumn = #aParam";
request.query(q, function(err, record) { ...
Those work just fine. Changing this to use LIKE, and I cannot get it to work. I've tried single quote before the % character, after, around it, just around the string, the whole thing, etc. Doing this:
q = "SELECT * FROM myTable WHERE theColumn LIKE " + "'%#aParam%'";
does not result in any errors, but returns no results. All other attempts with those single quotes results in query syntax errors. I cant seem to locate any documentation for parameterizing queries with wildcards. Where am I going wrong with this?

Answer 1

The syntax to do this is mentioned here - https://github.com/tediousjs/node-mssql/issues/332.
But in short:
q = `SELECT * FROM myTable WHERE theColumn LIKE '%' + #aParam + '%';`;

Unless you writing low level driver/worker, I would recommend to use any ORM:
const Sequelize = require('sequelize');
const sequelize = new Sequelize('database', 'username', 'password');
const MyTable = sequelize.define('myTable', {
theColumn: Sequelize.STRING
});
const aVar = 'somestring';
const results = await MyTable.findAll({
where: {
theColumn: { $like: `%${aVar}%` }
}
});
})
console.dir(results);
await can be used only inside async functions. For Framework supporting this out of the box take a look at Koa.js https://github.com/koajs/koa
