ingres_unbuffered_query

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.

See also the ingres.describe and ingres.utf8 directives in Runtime Configuration.

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().
