INGRES_PREPARE(3) 1 INGRES_PREPARE(3)
ingres_prepare - Prepare a query for later execution
SYNOPSIS
mixed ingres_prepare (resource $link, string $query)
DESCRIPTION
Prepares a query for execution by ingres_execute(3).
The query becomes part of the currently open transaction. If there is no open transaction, ingres_query(3) opens a new transaction. To
close the transaction, you can call either ingres_commit(3) to commit the changes made to the database or ingres_rollback(3) to cancel
these changes. When the script ends, any open transaction is rolled back (by calling ingres_rollback(3)). You can also use ingres_autocom-
mit(3) before opening a new transaction to have every SQL query immediately committed.
Note
Related Configurations
See also the ingres.describe, ingres.scrollable and ingres.utf8 directives in Runtime Configuration.
PARAMETERS
o $link
- The connection link identifier
o $query
- A valid SQL query (see the Ingres SQL reference guide) in the Ingres documentation. See the query parameter in ingres_query(3)
for a list of SQL statements which cannot be executed using ingres_prepare(3)
RETURN VALUES
ingres_prepare(3) returns a query result identifier that is used with ingres_execute(3) to execute the query. To see if an error occurred,
use ingres_errno(3), ingres_error(3), or ingres_errsqlstate(3).
