ingres_unbuffered_query() sends the given query
to the Ingres server.
The query becomes part of the currently open transaction. If there is no open transaction, ingres_unbuffered_query() opens a new transaction. To close the transaction, you can call either ingres_commit() to commit the changes made to the database or ingres_rollback() to cancel these changes. When the script ends, any open transaction is rolled back (by calling ingres_rollback()). You can also use ingres_autocommit() before opening a new transaction to have every SQL query immediately committed. Ingres allows only a single unbuffered statement to be active at any one time. The extension will close any active unbuffered statements before executing any SQL. In addition you cannot use ingres_result_seek() to position the row before fetching.

The connection link identifier
A valid SQL query (see the Ingres SQL reference guide) in the Ingres documentation. See the query parameter in ingres_query() for a list of SQL statements that cannot be executed via ingres_unbuffered_query().
Data inside the query should be properly escaped.
An array of parameter values to be used with the query
A string containing a sequence of types for the parameter values passed. See the types parameter in ingres_query() for the list of type codes.
ingres_unbuffered_query() returns a query result identifier when there are rows to fetch; else it returns FALSE
when there are no rows, as is the case of an INSERT, UPDATE, or DELETE statement. To see if an error occurred, use ingres_errno(), ingres_error(), or ingres_errsqlstate().
<?php $link = ingres_connect("demodb"); $result = ingres_unbuffered_query($link, "select * from user_profile"); while ($row = ingres_fetch_row($result)) { echo $row[1]; echo $row[2]; } ?>
<?php $link = ingres_connect("demodb"); $params[] = "Emma"; $query = "select * from user_profile where up_first = ?"; $result = ingres_unbuffered_query($link, $query, $params); while ($row = ingres_fetch_row($result)) { echo $row[1]; echo $row[2]; } ?>
<?php $link = ingres_connect("demodb"); //Open a photo $fh = fopen("photo.jpg","r"); $blob_data = stream_get_contents($fh); fclose($fh); //Prepare parameters $params[] = $blob_data; $params[] = 1201; //Define parameter types $param_types = "Bi"; $query = "update user_profile set up_image = ? where up_id = ?"; $result = ingres_unbuffered_query($link, $query , $params, $param_types); if (ingres_errno()) { echo ingres_errno() . "-" . ingres_error() . "\n"; } ?>
