Is there an example on how to use the WHERE field IN clause?

Hi Patrik,

I’m trying to perform a simple select query as below:

select * from user_table where id in (@id)

I specify the id parameter as a string ‘1,2,3’, but somehow SQL server fails to Convert this from nvarchar to int. I am relying on .input() function’s capability of assigning a type, when it is unspecified.

However, when I do a query from SQL Server, the query select * from user_table where id in (1,2,3) works well.

An example on how to use the WHERE field IN clause would be very useful.

@rohithshenoyg , you could do a reduce on your array to construct the SQL string. Something like:

const array = [1, 2, 3]
const sqlString = `SELECT * FROM user_table WHERE id IN (${array.reduce((prev, curr) => {
  return `${prev},${curr}`;
})})`;
request.query(sqlString);

Array.join is much simpler there:

$ node --harmony
> const array = [1, 2, 3]
undefined
> const str0 = `SELECT * FROM user_table WHERE id IN (${array.join(',')})`
undefined
> str0
'SELECT * FROM user_table WHERE id IN (1,2,3)'
