PHP 忒聊 綴豖 ヶ輛 dbx_query (PHP 4 = 4.0.6) Description dbx_query() returns an object or 1 on success, and 0 on failure. The result object is returned only if the query given in sql_statement produces a result set. 瞰赽 1. How to handle the returned value ?php $link = dbx_connect(DBX_ODBC, "", "db", "username", "password") or die("Could not connect"); $result = dbx_query($link, 'SELECT id, parentid, description FROM table'); if (is_object($result)) {//... do some stuff here, see detailed examples below... // first, print out field names and types // then, draw a table filled with the returned field values} else if ($result == 1) {echo("Query executed successfully, but no result set returned");} else {exit("Query failed");} dbx_close($link);? The flags parameter is used to control the amount of information that is returned. It may be any combination of the following constants with the bitwise OR operator (|). The DBX_COLNAMES_* flags override the dbx.colnames_case setting from php.ini. It is always set, that is, the returned object has a data property which is a 2 dimensional array indexed numerically. For example, in the expression data[2][3] 2 stands for the row (or record) number and 3 stands for the column (or field) number. The first row and column are indexed at 0. If DBX_RESULT_ASSOC is also specified, the returning object contains the information related to DBX_RESULT_INFO too, even if it was not specified. It provides info about columns, such as field names and field types. It effects that the field values can be accessed with the respective column names used as keys to the returned object's data property. Associated results are actually references to the numerically indexed data, so modifying data[0][0] causes that data[0]['field_name_for_first_column'] is modified as well. The case of the returned column names will not be changed. The case of the returned column names will be changed to uppercase. The case of the returned column names will be changed to lowercase. DBX_RESULT_INDEX DBX_RESULT_INDEX | DBX_RESULT_INFO DBX_RESULT_INDEX | DBX_RESULT_INFO | DBX_RESULT_ASSOC - this is the default, if flags is not specified. The returing object has four or five properties depending on flags: It is a valid handle for the connected database, and as such it can be used in module specific functions (if required). $result = dbx_query ($link, "SELECT id FROM table"); mysql_field_len ($result- handle, 0); These contain the number of columns (or fields) and rows (or records) respectively. $result = dbx_query ($link, 'SELECT id FROM table'); echo $result- rows; // number of records echo $result- cols; // number of fields It is returned only if either DBX_RESULT_INFO or DBX_RESULT_ASSOC is specified in the flags parameter. It is a 2 dimensional array, that has two named rows (name and type) to retrieve column information. 瞰赽 2. lists each field's name and type $result = dbx_query ($link, 'SELECT id FROM table', DBX_RESULT_INDEX | DBX_RESULT_INFO); for ($i = 0; $i $result- cols; $i++) {echo $result- info['name'][$i]. "\n"; echo $result- info['type'][$i]. "\n";} This property contains the actual resulting data, possibly associated with column names as well depending on flags. If DBX_RESULT_ASSOC is set, it is possible to use $result- data[2]["field_name"]. 瞰赽 3. outputs the content of data property into HTML table $result = dbx_query ($link, 'SELECT id, parentid, description FROM table'); echo "table \n"; foreach ($result- data as $row) {echo" tr \n"; foreach ($row as $field) {echo "td $field /td ";} echo" /tr \n";} echo "/table \n"; 蛁: Always refer to the module-specific documentation as well. Column names for queries on an Oracle database are returned in lowercase. See also: dbx_escape_string() and dbx_connect(). 綴豖 れ萸 ヶ輛 dbx_escape_string 奻珨撰 dbx_sort
