px_retrieve_record
Descrizione
array px_retrieve_record ( resource pxdoc, int num [, int mode] )This function is very similar to px_get_record() but uses internally a different approach to retrieve the data. It relies on pxlib for reading each single field value, which usually results in support for more field types.
Nota: This function is only available if pxlib >= 0.6.0 is used.
Elenco dei parametri
- pxdoc
Resource identifier of the paradox database as returned by px_new().
- num
The record number is an artificial number counting records in the order as they are stored in the database. The first record has number 0.
- mode
The optional mode can be PX_KEYTOLOWER or PX_KEYTOUPPER in order to convert the keys into lower or upper case. If mode is not passed or is 0, then the key will be exactly like the field name. The element values will contain the field values. NULL values will be retained and are different from 0.0, 0 or the empty string. Fields of type PX_FIELD_TIME will be returned as an integer counting the number of milliseconds starting at midnight. A timestamp is a floating point value also counting milliseconds starting at the beginning of julian calendar.
Valori restituiti
