if set to TRUE the array result be modified as follows:
If the result set contains more than two columns, the value
will be an array of the values from column 2 to n. If the result
set contains only two columns, the returned value will be a
scalar with the value of the second column (unless forced to an
array with the $force_array parameter).
boolean
$force_array
used only if the query returns
exactly two columns.
If TRUE, the values of the returned array
will be one-element arrays instead of scalars.
boolean
boolean $group
if TRUE, the values of
the returned array is wrapped in another array.
If the same key value (in the first column)
repeats itself, the values
will be appended to this array instead
of overwriting the
existing values.
Check the SQL fetch or choose another
fetch*() function
every other error code
Database specific error
Check the database related section of
PHP-Manual
to detect the reason for this error. In the most cases
a misformed SQL statment. Ie. using LIMIT in a SQL-Statment
for an Oracle database.
