I ran into this exception while trying to make some dynamic SOQL queries(also SOSL but haven't gotten to test those yet).

Basically I'm trying to build a query string and add a dynamic value as one of the parameters. Problem is I don't know what type that value will be(string, integer, etc). I don't think I can manually cast to all possible types, I'm looking for a more elegant solution.
Code in question:

qryHolder = 'SELECT {0} FROM {1} WHERE {0} =: val';

Where val is String val = String.valueOf(sobj.get(fieldName.getName())); sobj is a random sobject, fieldName is Schema.DesribeFieldResult.
I can also make something like 

'SELECT {0} FROM {1} WHERE {0} = {2}'

And {2} would be val but then it doesn't work for Strings and only work for Numbers.
Any solution to this?

Reset to default

Bind to an Object.

Then you can set values which will work for a number field: 

Object val = 42;

Or a text field: 

Object val = 'Some text';

And so on.
