ora_columnsize — Gets the size of an Oracle result column.


int ora_columnsize(cursor, column);
resource cursor: Cursor handle
int column: Column number


Column size; FALSE on error


Returns the column size specified at the column number. Column numbering starts at 0. The column size is either the maximum size of the number that can be stored, in the case of a NUMBER column, or the maximum number of characters that can be stored, in the case of CHAR, VARCHAR, and VARCHAR2 columns.


As of versions 3.0 and 4.0


Example 879. Display column size

// open a connection
if (!$db = @ora_logon("dev@ORCL","dev")) {
   $error = ora_error();
   printf("There was an error connecting. Error was: %s", $error);

// open a cursor
$curs = ora_open($db);

// check that SQL is OK
if (!@ora_parse($curs,"SELECT * FROM xphone_numbers")) {
   echo "Error in parse. Error was :", ora_error($curs);
} else {
   $ncols = ora_numcols($curs);

   echo "<table>\n";
   echo "<tr><th>Name</th><th>Size</th></tr>\n";

   // loop through the number of columns, returning the column size
   for ( $i = 0; $i < $ncols; $i++ ) {
      printf("<td>%s</td>", ora_columnname($curs,$i));
      printf("<td>%s</td>", ora_columnsize($curs,$i));


// log off and disconnect
