How to query CosmosDb for multiple results using SqlQuerySpec - sql

Question

I'm trying to get multiple documents using a list of numbers. Here's my query
var queryString = "Select * from c Where c.id in (#list)";
var queryParam = new Microsoft.Azure.Documents.SqlParameter("#list", string.Join(",", list.Select(x => $"{x.Id}").ToArray()));
var result = repo.Query(
new SqlQuerySpec()
{
QueryText = queryString,
Parameters = new Microsoft.Azure.Documents.SqlParameterCollection()
{
queryParam
}
}
);
My Query function:
public IQueryable<TClass> Query(SqlQuerySpec sqlQuerySpec = null, bool allowScan = false, int? maxItems = null)
{
var feedOptions = new FeedOptions
{
EnableScanInQuery = allowScan,
MaxItemCount = maxItems,
EnableCrossPartitionQuery = true
};
var querySpec = sqlQuerySpec ?? new SqlQuerySpec();
return sqlQuerySpec != null
? Client.CreateDocumentQuery<TClass>(Collection.DocumentsLink, querySpec, feedOptions)
: Client.CreateDocumentQuery<TClass>(Collection.DocumentsLink, feedOptions);
}
It says there was an error: one of the specified inputs is invalid.
What am I doing wrong?

The id is a string so you would need to wrap each id with single quotes.
This line:
var queryParam = new Microsoft.Azure.Documents.SqlParameter("#list", string.Join(",", list.Select(x => $"{x.Id}").ToArray()));
Should be:
var queryParam = new Microsoft.Azure.Documents.SqlParameter("#list", string.Join(",", list.Select(x => $"'{x.Id}'").ToArray()));
