Normally we write the processing of SQL statements in a server-side scripting language meant for the web, using "created for the web languages" like PHP or Javascript.
Also, depending on how you write your SQL select query, the results of the select query are generally in an array and so the script generally needs to process an array, not a simple string or text file.
However, if you are looking for a single element only from the SQL select query, the results of the SQL query are often still in an array, a single element array.
So, in the general case, you should write your script to process an array as the input to your script which is the output of the SQL query.

ingres_prepare
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).
