Unable to use TVP as query input

Providing Table Value Parameter as input to query fails on sp_executesql

Expected behaviour:

The query to execute successfully and give the result of

Actual behaviour:

The query fails to execute due to an issue with sp_executesql

Example that works in raw tsql

CREATE TYPE MyAwesomeType AS TABLE (storeNbr INT);

DECLARE @tvp StoreNumberTableType
INSERT INTO @tvp
VALUES (1), (2)

exec sp_executesql N'SELECT * FROM @tvp', N'@tvp MyAwesomeType readonly', @tvp

Translated example that fails in node-mssql

const t = new sql.Table('MyAwesomeType');

t.columns.add('storeNbr', sql.Int);
t.rows.add(1);
t.rows.add(2);

const req = connection.request();

req.input('tvp', t);
return req.query(`SELECT * from @tvp`);

Configuration:

Software versions

@dhensby Looks like this is an issue with the way the underlying tediousjs library handles executing raw queries. Will close this issue and continue looking into this issue at the tedious layer. Will link the PR here, if I am able to figure out an acceptable fix.

I will look into it and see if I can figure it out to submit a PR. Thank you.
