Binds a PHP variable to a corresponding named or question mark placeholder in the SQL statement that was use to prepare the statement. Unlike PDOStatement->bindValue(), the variable is bound as a reference and will only be evaluated at the time that PDOStatement->execute() is called.

Most parameters are input parameters, that is, parameters that are used in a read-only fashion to build up the query. Some drivers support the invocation of stored procedures that return data as output parameters, and some also as input/output parameters that both send in data and are updated to receive it.

Parameters:

param - Parameter identifier. For a prepared statement using named placeholders, this will be a parameter name of the form :name. For a prepared statement using question mark placeholders, this will be the 1-indexed position of the parameter

variable - Name of the PHP variable to bind to the SQL statement parameter.

type - Explicit data type for the parameter using the PDO::PARAM_* constants. To return an INOUT parameter from a stored procedure, use the bitwise OR operator to set the PDO::PARAM_INPUT_OUTPUT bits for the data_type parameter.

Returns:

Returns TRUE on success or FALSE on failure.

Binds a value to a corresponding named or positional placeholder in the SQL statement that was used to prepare the statement.

Parameters:

param - Parameter identifier. For a prepared statement using named placeholders, this will be a parameter name of the form :name. For a prepared statement using question mark placeholders, this will be the 1-indexed position of the parameter

value - The value to bind to the parameter.

type - Explicit data type for the parameter using the PDO::PARAM_* constants.

Returns:

Returns TRUE on success or FALSE on failure.

Closes the cursor, enabling the statement to be executed again.

Returns:

Returns TRUE on success or FALSE on failure.

columnCount Returns the number of columns in the result set

Returns:

Returns the number of columns in the result set represented by the PDOStatement object. If there is no result set, this method should return 0.

errorCode Fetch the SQLSTATE associated with the last operation on the statement handle

See Also:

Doctrine_Adapter_Interface::errorCode()

Returns:

error code string

errorInfo Fetch extended error information associated with the last operation on the statement handle

See Also:

Doctrine_Adapter_Interface::errorInfo()

Returns:

error info array

Executes a prepared statement

If the prepared statement included parameter markers, you must either: call PDOStatement->bindParam() to bind PHP variables to the parameter markers: bound variables pass their value as input and receive the output value, if any, of their associated parameter markers or pass an array of input-only parameter values

Parameters:

params - An array of values with as many elements as there are bound parameters in the SQL statement being executed.

Returns:

Returns TRUE on success or FALSE on failure.

fetch

See Also:

constants

Parameters:

fetchStyle - Controls how the next row will be returned to the caller. This value must be one of the Query::HYDRATE_* constants, defaulting to Query::HYDRATE_BOTH

cursorOrientation - For a PDOStatement object representing a scrollable cursor, this value determines which row will be returned to the caller. This value must be one of the Query::HYDRATE_ORI_* constants, defaulting to Query::HYDRATE_ORI_NEXT. To request a scrollable cursor for your PDOStatement object, you must set the PDO::ATTR_CURSOR attribute to Doctrine::CURSOR_SCROLL when you prepare the SQL statement with Doctrine_Adapter_Interface->prepare().

cursorOffset - For a PDOStatement object representing a scrollable cursor for which the $cursorOrientation parameter is set to Query::HYDRATE_ORI_ABS, this value specifies the absolute number of the row in the result set that shall be fetched. For a PDOStatement object representing a scrollable cursor for which the $cursorOrientation parameter is set to Query::HYDRATE_ORI_REL, this value specifies the row to fetch relative to the cursor position before PDOStatement->fetch() was called.

Returns an array containing all of the result set rows

Parameters:

fetchStyle - Controls how the next row will be returned to the caller. This value must be one of the Query::HYDRATE_* constants, defaulting to Query::HYDRATE_BOTH

columnIndex - Returns the indicated 0-indexed column when the value of $fetchStyle is Query::HYDRATE_COLUMN. Defaults to 0.

fetchColumn Returns a single column from the next row of a result set or FALSE if there are no more rows.

Parameters:

columnIndex - 0-indexed number of the column you wish to retrieve from the row. If no value is supplied, PDOStatement->fetchColumn() fetches the first column.

Returns:

returns a single column in the next row of a result set.

rowCount rowCount() returns the number of rows affected by the last DELETE, INSERT, or UPDATE statement executed by the corresponding object.

If the last SQL statement executed by the associated Statement object was a SELECT statement, some databases may return the number of rows returned by that statement. However, this behaviour is not guaranteed for all databases and should not be relied on for portable applications.

Returns:

Returns the number of rows.
