MonetDB-PHP Error on parameterized query with timestamp

4 Dec 2020


      Hi,
The below is from my colleague who is not a member on this list, so I'm sending on his behalf.
I'm using MonetDB with MonetDB-PHP library.
I have followed the documentation from: https://github.com/MonetDB/MonetDB-PHP
Everything is working fine, but if I set parameter for timestamp type column I get the following error:
Error from MonetDB: 42000!Wrong type for argument 1 of function call: char, expected timestamp
For example, this is working:
$result = $connection->Query('
    select
        *
    from
        "cats"
    where
        "name" = ?
        and "weight_kg" > ?
    limit
        10', [ "D'artagnan", 5.3 ]);
but this will not work:
$result = $connection->Query('
    select
        *
    from
        "cats"
    where
        "name" = ?
        and "weight_kg" > ?
        and "birthdate" < ? // timestamp data type
    limit
        10
', [ "D'artagnan", 5.3, "2020-02-28 12:37:16" ]);
The error occurs for any column that is of timestamp type and only when passing value as parameter.
What am I doing wrong?
Thank you.
