List of PDOStatement::bindParam data_type parameters

Question

Is there a list describing all of the data_type parameters you can use in PDOStatement::bindParam() ? If none, what do you commonly use, and for what type of field ?

According to PHP manual: data_type Explicit data type for the parameter using the PDO::PARAM_* constants.

I know about the PDO::PARAM_INT and PDO::PARAM_STR . I've heard of PDO::PARAM_LOB but I wasn't sure how and when to use that, though. (for date ?)

From the documentation here:

PDO::PARAM_BOOL (integer)
Represents a boolean data type.
PDO::PARAM_NULL (integer)
Represents the SQL NULL data type.
PDO::PARAM_INT (integer)
Represents the SQL INTEGER data type.
PDO::PARAM_STR (integer)
Represents the SQL CHAR, VARCHAR, or other string data type.
PDO::PARAM_LOB (integer)
Represents the SQL large object data type.
PDO::PARAM_STMT (integer)
Represents a recordset type. Not currently supported by any drivers.
PDO::PARAM_INPUT_OUTPUT (integer)
Specifies that the parameter is an INOUT parameter for a stored procedure. You must bitwise-OR this value with an explicit PDO::PARAM_* data type.
