Can't call databasepropertyex() on MSSQL over tds version 8.0

Hi guys,

Suppose in my /etc/freetds/freetds.conf I have:

[global]
        tds version = 7.0

Then this works:

echo "select databasepropertyex(DB_NAME(), 'Collation')\ngo" | tsql -H server -p 5000 -U sa -P pass
locale is
"LC_CTYPE=en_US.utf8;LC_NUMERIC=en_US.UTF-8;LC_TIME=en_US.UTF-8;LC_COLLATE=en_US.UTF-8;LC_MONETARY=en_US.UTF-8;LC_MESSAGES=en_US.UTF-8;LC_PAPER=en_US.UTF-8;LC_NAME=en_US.UTF-8;LC_ADDRESS=en_US.UTF-8;LC_TELEPHONE=en_US.UTF-8;LC_MEASUREMENT=en_US.UTF-8;LC_IDENTIFICATION=en_US.UTF-8"
locale charset is "UTF-8"

If I change it to:

[global]
        tds version = 8.0

Then the query no longer works:

echo "select databasepropertyex(DB_NAME(), 'Collation')\ngo" | tsql -H server -p 5000 -U sa -P pass
locale is
"LC_CTYPE=en_US.utf8;LC_NUMERIC=en_US.UTF-8;LC_TIME=en_US.UTF-8;LC_COLLATE=en_US.UTF-8;LC_MONETARY=en_US.UTF-8;LC_MESSAGES=en_US.UTF-8;LC_PAPER=en_US.UTF-8;LC_NAME=en_US.UTF-8;LC_ADDRESS=en_US.UTF-8;LC_TELEPHONE=en_US.UTF-8;LC_MEASUREMENT=en_US.UTF-8;LC_IDENTIFICATION=en_US.UTF-8"
locale charset is "UTF-8"
