SPI_MODIFYTUPLE(3)					  PostgreSQL 9.2.7 Documentation					SPI_MODIFYTUPLE(3)

NAME

       SPI_modifytuple - create a row by replacing selected fields of a given row

SYNOPSIS

       HeapTuple SPI_modifytuple(Relation rel, HeapTuple row, int ncols,
				 int * colnum, Datum * values, const char * nulls)

DESCRIPTION

       SPI_modifytuple creates a new row by substituting new values for selected columns, copying the original row's columns at other positions.
       The input row is not modified.

ARGUMENTS

       Relation rel
	   Used only as the source of the row descriptor for the row. (Passing a relation rather than a row descriptor is a misfeature.)

       HeapTuple row
	   row to be modified

       int ncols
	   number of column numbers in the array colnum

       int * colnum
	   array of the numbers of the columns that are to be changed (column numbers start at 1)

       Datum * values
	   new values for the specified columns

       const char * Nulls
	   which new values are null, if any (see SPI_execute_plan for the format)

RETURN VALUE

       new row with modifications, allocated in the upper executor context; NULL only if row is NULL

       On error, SPI_result is set as follows:

       SPI_ERROR_ARGUMENT
	   if rel is NULL, or if row is NULL, or if ncols is less than or equal to 0, or if colnum is NULL, or if values is NULL.

       SPI_ERROR_NOATTRIBUTE
	   if colnum contains an invalid column number (less than or equal to 0 or greater than the number of column in row)

MSQL_FETCH_ROW(3)														 MSQL_FETCH_ROW(3)

msql_fetch_row - Get row as enumerated array

SYNOPSIS

       array msql_fetch_row (resource  $result)

DESCRIPTION

       msql_fetch_row(3)  fetches one row of data from the result associated with the specified query identifier. The row is returned as an array.
       Each result column is stored in an array offset, starting at offset 0.

	Subsequent call to msql_fetch_row(3) would return the next row in the result set, or FALSE if there are no more rows.

PARAMETERS

	      o $
		result -The result resource that is being evaluated. This result comes from a call to msql_query(3).

RETURN VALUES

	Returns an array that corresponds to the fetched row, or FALSE if there are no more rows.

EXAMPLES

       Example #1

	      msql_fetch_row(3) example

	      <?php
	      $con = msql_connect();
	      if (!$con) {
		  die('Server connection problem: ' . msql_error());
	      }

	      if (!msql_select_db('test', $con)) {
		  die('Database connection problem: ' . msql_error());
	      }

	      $result = msql_query('SELECT id, name FROM people', $con);
	      if (!$result) {
		  die('Query execution problem: ' . msql_error());
	      }

	      while ($row = msql_fetch_row($result)) {
		  echo $row[0] . ': ' . $row[1] . "
";
	      }

	      msql_free_result($result);
	      ?>
