Re: MonetDB-PHP Error on parameterized query with timestamp

7 Dec 2020

      Hi Sjoerd,

Thank you for getting back to me.

My colleague tested what you suggested and got the same error so it is still failing. He is certain he is passing the correct value as he is able to execute the same query in raw format, so he believed it has to do with the way params are implemented. I'm no expert but he said it looks like an error from C language.

Please advise.

Thank you.

Regards,

Kevork Vartanian

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.
