Function Documentation

DuiDBRecordSet* dui_libpq_connection_exec	(	DuiDBConnection *	,
		const char *	buff
	)

Issue a query on this connection. FYI -- the query is actually performed asynchronously; the record set may not yet contain valid data when this routine returns.

DuiDBConnection* dui_libpq_connection_new	(	const char *	dbname,
		const char *	username,
		const char *	authentication_token
	)

establish new connection to indicated database

const char* dui_libpq_recordset_get_value	(	DuiDBRecordSet *	rs,
		const char *	fieldname
	)

Get the field value by name. This is a little different/easier than the usual trick of getting it by column number. Slower too.

void dui_libpq_recordset_release

(

DuiDBRecordSet *

)

Release the record set when one is done with it

int dui_libpq_recordsettch_row

(

DuiDBRecordSet *

)

Prep a row. Basically, this gets the 'next' row out of the database. Subsequent field fetches are for this row. Returns zero if there are no more rows.
