SQLite3: the params is passed directly to the sqlite3_open() function as a filename to be opened (check SQLite3 documentation for more details). </dd>

MySQL: the params can have "host", "port", "user", "pass", "dbname", "sock", "flags" "fldsz", "group" and "reconnect" keys, each followed by an equal sign and a value. Such key/value pairs can be delimited by space, CR, LF, tab, semicolon, vertical bar or comma. For now, "flags" can only recognise CLIENT_FOUND_ROWS (check MySQL manual for details). The value associated with "fldsz" determines maximum amount of memory (in bytes) for each of the fields in the result set of prepared statements. By default, this value is 1 MB. The value associated with "group" determines which group from configuration file to use (see MYSQL_READ_DEFAULT_GROUP option of mysql_options() in MySQL manual). Reconnect is set to 1 by default (i.e. true). </dd>

For instance: "SELECT name FROM customers WHERE name=%s" would be a query that this function understands. </dd>
<dd>
Here is the full list of format specifiers that this function understands and what they map to in SQL: %hhd (TINY INT), %hhu (UNSIGNED TINY INT), %hd (SHORT), %hu (UNSIGNED SHORT), %d (INT), %u (UNSIGNED INT), %ld (LONG), %lu (UNSIGNED LONG), %lld (LONG LONG), %llu (UNSIGNED LONG LONG), %f (FLOAT, REAL), %lf (DOUBLE PRECISION), %s (VARCHAR), %pDt (TEXT), %pDi (TIME), %pDd (DATE), %pDa (DATETIME), %pDs (TIMESTAMP), %pDz (TIMESTAMP WITH TIME ZONE), %pDb (BLOB), %pDc (CLOB) and %pDn (NULL). Not all databases have support for all these types, so the underlying driver will attempt the "best match" where possible. A % followed by any letter not in the above list will be interpreted as VARCHAR (i.e. %s). </dd></dl>
