Inherited by MSSQLResultSet, MySQLResultSet, OCI8ResultSet, PgSQLResultSet, and SQLiteResultSet.
resource ResultSet::getResource ( ) |
Get the PHP native resource for the result. Arguably this should not be part of the interface: i.e. every driver should implement it if they have a result resource, but conceivably drivers could be created that do not. For now every single driver does have a "dblink" resource property, and other classes (e.g. ResultSet) need this info in order to get correct native errors. We'll leave it in for now, as it helps with driver development, with the caveat that it could be removed from the interface at a later point.
|
void ResultSet::setFetchmode ( $ mode ) |
Sets the fetchmode used to retrieve results. Changing fetchmodes mid-result retrieval is supported (haven't encountered any drivers that don't support that yet).
|
int ResultSet::getFetchmode ( ) |
Gets the fetchmode used to retrieve results.
|
boolean ResultSet::isIgnoreAssocCase ( ) |
Whether assoc result keys get left alone -- as opposed to converted to lowercase. If the case change stuff goes back to being more complicated (allowing conver to upper, e.g.) then we'll add new methods but this method will always indicate whether any case conversions should be (or have been) performed at all. This defaults to true unless Creole::NO_ASSOC_LOWER flag has been passed to connection. This property is read-only since it must be set when connection is created. The reason for this behavior is some drivers (e.g. SQLite) do the case conversions internally based on a PHP ini value; it would not be possible to change the behavior from the ResultSet (since query has already been executed).
|
boolean ResultSet::next ( ) |
Moves the internal cursor to the next position and fetches the row at that position.
Implemented in MSSQLResultSet, MySQLResultSet, OCI8ResultSet, PgSQLResultSet, and SQLiteResultSet. |
boolean ResultSet::previous ( ) |
Moves the internal cursor to the previous position and fetches the row at that position.
|
boolean ResultSet::relative ( $ offset ) |
Moves the cursor a relative number of rows, either positive or negative and fetches the row at that position. Attempting to move beyond the first/last row in the result set positions the cursor before/after the first/last row and issues a Warning. Calling relative(0) is valid, but does not change the cursor position.
|
boolean ResultSet::absolute ( $ pos ) |
Moves the cursor to an absolute cursor position and fetches the row at that position. Attempting to move beyond the first/last row in the result set positions the cursor before/after the first/last row and issues a Warning.
|
boolean ResultSet::seek ( $ rownum ) |
Moves cursor position WITHOUT FETCHING ROW AT THAT POSITION. Generally this method is for internal driver stuff (e.g. other methods like absolute() or relative() might call this and then call next() to get the row). This method is public to facilitate more advanced ResultSet scrolling tools -- e.g. cleaner implimentation of ResultSetIterator. Some drivers will emulate seek() and not allow reverse seek (Oracle). Seek is 0-based, but seek() is only for moving to the space _before_ the record that you want to read. I.e. if you seek(0) and then call next() you will have the first row (i.e. same as calling first() or absolute(1)).
IMPORTANT: You cannot rely on the return value of this method to know whether a given record exists for reading. In some cases seek() will correctly return
Implemented in MSSQLResultSet, MySQLResultSet, OCI8ResultSet, PgSQLResultSet, and SQLiteResultSet. |
boolean ResultSet::first ( ) |
Move cursor to beginning of recordset.
|
boolean ResultSet::last ( ) |
Move cursor to end of recordset.
|
void ResultSet::beforeFirst ( ) |
Sets cursort to before first record. This does not actually seek(), but simply sets cursor pos to 0. This is useful for inserting a record before the first in the set, etc.
|
void ResultSet::afterLast ( ) |
Sets cursort to after the last record. This does not actually seek(), but simply sets the cursor pos to last + 1. This [will be] useful for inserting a record after the last in the set, when/if Creole supports updateable ResultSets.
|
boolean ResultSet::isAfterLast ( ) |
Checks whether cursor is after the last record.
|
boolean ResultSet::isBeforeFirst ( ) |
Checks whether cursor is before the first record.
|
int ResultSet::getCursorPos ( ) |
Returns the current cursor position. Cursor positions start at 0, but as soon as first row is fetched cursor position is 1. (so first row is 1)
|
array ResultSet::getRow ( ) |
Gets current fields (assoc array).
|
int ResultSet::getRecordCount ( ) |
Get the number of rows in a result set.
Implemented in MSSQLResultSet, MySQLResultSet, OCI8ResultSet, PgSQLResultSet, and SQLiteResultSet. |
void ResultSet::close ( ) |
Frees the resources allocated for this result set. Also empties any internal field array so that any calls to get() method on closed ResultSet will result in "Invalid column" SQLException.
Reimplemented from IteratorAggregate. Implemented in MSSQLResultSet, MySQLResultSet, OCI8ResultSet, PgSQLResultSet, and SQLiteResultSet. |
mixed ResultSet::get ( $ column ) |
A generic get method returns unformatted (=string) value. This returns the raw results from the database. Usually this will be a string, but some drivers also can return objects (lob descriptors, etc) in certain cases.
|
array ResultSet::getArray ( $ column ) |
Reads a column as an array. The value of the column is unserialized & returned as an array. The generic case of this function is very PHP-specific. Other drivers (e.g. Postgres) will format values into their native array format.
Implemented in PgSQLResultSet. |
boolean ResultSet::getBoolean ( $ column ) |
Returns value translated to boolean. Default is to map 0 => false, 1 => true, but some database drivers may override this behavior.
Implemented in PgSQLResultSet. |
Blob ResultSet::getBlob ( $ column ) |
Returns Blob with contents of column value.
Implemented in PgSQLResultSet, and SQLiteResultSet. |
Clob ResultSet::getClob ( $ column ) |
Returns Clob with contents of column value.
|
mixed ResultSet::getDate
(
$
column,
$
format = '%x'
)
|
Return a formatted date. The default format for dates returned is preferred (in your locale, as specified using setlocale()) format w/o time (i.e. strftime("%x", $val)). Override this by specifying a format second parameter. You can also specify a date()-style formatter; if you do, make sure there are no "%" symbols in your format string.
|
float ResultSet::getFloat ( $ column ) |
Returns value cast as a float (in PHP this is same as double).
|
int ResultSet::getInt ( $ column ) |
Returns value cast as integer.
|
string ResultSet::getString ( $ column ) |
Returns value cast as string.
Implemented in MySQLResultSet. |
mixed ResultSet::getTime
(
$
column,
$
format = '%X'
)
|
Return a formatted time. The default format for times returned is preferred (in your locale, as specified using setlocale()) format w/o date (i.e. strftime("%X", $val)). Override this by specifying a format second parameter. You can also specify a date()-style formatter; if you do, make sure there are no "%" symbols in your format string.
|
mixed ResultSet::getTimestamp
(
$
column,
$
format = 'Y-m-d H:i:s'
)
|
Return a formatted timestamp. The default format for timestamp is ISO standard YYYY-MM-DD HH:MM:SS (i.e. date('Y-m-d H:i:s', $val). Override this by specifying a format second parameter. You can also specify a strftime()-style formatter. Hint: if you want to get the unix timestamp use the "U" formatter string.
Implemented in MySQLResultSet. |
const ResultSet::FETCHMODE_ASSOC = 1 |
Index result set by field name. |
const ResultSet::FETCHMODE_NUM = 2 |
Index result set numerically. |
