Can we delete a list of Ids from database? - sql

Question

Can we delete a list of Ids (int[]) in database from react? I have below and it doesn't work ... error message is: SyntaxError: Unexpected token 'M', "Microsoft."... is not valid JSON
==================================================
deleteIdList()
{
const idList = this.state.selectedEmployeeIdList;
if (window.confirm('Are you sure list of Employee(s)?'))
{
fetch(variables.API_URL + 'employee/' + idList, {
method : 'DELETE',
headers : {
'Accept' : 'application/json',
'Content-Type' : 'application/json'
}
})
.then(res=>res.json())
.then((result) => {
alert('deleted')
alert(result);
this.refreshList();
},(error)=>{
alert('Cannot Delete Selected Employee(s)!!!!! ' + error);
})
}
}
In VS 2019:
[HttpDelete("{id}")]
public JsonResult Delete(int[] id)
{
string query = #"DELETE FROM DBO.EMPLOYEE WHERE EMPLOYEEID in #EMPLOYEEIDs";
DataTable table = new DataTable();
SqlDataReader dr;
string sqlDataSource = _configuration.GetConnectionString("EmployeeAppConn");
using (SqlConnection myConn = new SqlConnection(sqlDataSource))
{
myConn.Open();
using (SqlCommand cm = new SqlCommand(query, myConn))
{
cm.Parameters.AddWithValue("#EMPLOYEEIDs", id);
dr = cm.ExecuteReader();
table.Load(dr);
dr.Close();
myConn.Close();
}
}
return new JsonResult("Employee #" + id.ToString() + " deleted!");
}
