Guid assertion failed \tiberius-0.3.0\src\types\mod.rs:344:25

[johnfercher]

Tiberius is crashing when SELECT returns this guid F72BDC04-8837-4D3E-8C54-84A50A996BB1. This is a valid guid in Azure SQL Server.

Here is the code where panic is called.

VarLenType::Guid => {
    assert_eq!(trans.inner.read_u8()? as usize, *len);
    let mut data = [0u8; 16];
    try_ready!(trans.inner.read_bytes_to(&mut data));
    ColumnData::Guid(Cow::Owned(Guid(data)))
}

Here is the full error.

select cast('F72BDC04-8837-4D3E-8C54-84A50A996BB1' as uniqueidentifier) works fine for me, can you give me more information to reproduce?
A minimal query + dataset would be nice.

[johnfercher]

I made some tests with the query and I noticed a strange behavior.

This query works.

SELECT TOP(20) 
[Id], 
[YId], 
[ReceivedDate], 
[Status], 
[BuyerName], 
[IpAddress], 
[CustomerEmail], 
[CustomerIdentification], 
[HolderName], 
[Top], 
[Top12], 
[ShipPostalCode], 
[CustomerPostalCode], 
[OrderId] 
FROM [dbo].[Transaction]
WHERE [YId] = '9AAB0758-6666-7777-8888-AC506513739E'
AND [ReceivedDate] BETWEEN '2018-03-01T00:00:04.000000153+00:00' AND '2018-03-31T23:57:23.000000523+00:00'
ORDER BY ReceivedDate;

If I add a column Amount, the error assertion failed \tiberius-0.3.0\src\types\mod.rs:344:25 occurs.

SELECT TOP(20)
[Id],
[YId], 
[ReceivedDate], 
[Status], 
[BuyerName], 
[IpAddress], 
[CustomerEmail], 
[CustomerIdentification], 
[HolderName], 
[Top], 
[Top12], 
[ShipPostalCode], 
[CustomerPostalCode], 
[OrderId], 
[Amount]
FROM [dbo].[Transaction]
WHERE [YId] = '9AAB0758-6666-7777-8888-AC506513739E'
AND [ReceivedDate] BETWEEN '2018-03-01T00:00:04.000000153+00:00'
AND '2018-03-31T23:57:23.000000523+00:00'
ORDER BY ReceivedDate;

If run a query selecting only Amount it works.

SELECT TOP(20)
[Amount]
FROM [dbo].[Transaction]
WHERE [YId] = '9AAB0758-6666-7777-8888-AC506513739E'
AND [ReceivedDate] BETWEEN '2018-03-01T00:00:04.000000153+00:00' AND '2018-03-31T23:57:23.000000523+00:00'
ORDER BY ReceivedDate;
