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.
