DB2_PREPARE(3) 1 DB2_PREPARE(3) db2_prepare - Prepares an SQL statement to be executed SYNOPSIS
resource db2_prepare (resource $connection, string $statement, [array $options]) DESCRIPTION
db2_prepare(3) creates a prepared SQL statement which can include 0 or more parameter markers ( ? characters) representing parameters for input, output, or input/output. You can pass parameters to the prepared statement using db2_bind_param(3), or for input values only, as an array passed to db2_execute(3). There are three main advantages to using prepared statements in your application: o Performance: when you prepare a statement, the database server creates an optimized access plan for retrieving data with that statement. Subsequently issuing the prepared statement with db2_execute(3) enables the statements to reuse that access plan and avoids the overhead of dynamically creating a new access plan for every statement you issue. o Security: when you prepare a statement, you can include parameter markers for input values. When you execute a prepared statement with input values for placeholders, the database server checks each input value to ensure that the type matches the column defini- tion or parameter definition. o Advanced functionality: Parameter markers not only enable you to pass input values to prepared SQL statements, they also enable you to retrieve OUT and INOUT parameters from stored procedures using db2_bind_param(3). PARAMETERS
o $connection - A valid database connection resource variable as returned from db2_connect(3) or db2_pconnect(3). o $statement - An SQL statement, optionally containing one or more parameter markers.. o $options - An associative array containing statement options. You can use this parameter to request a scrollable cursor on database servers that support this functionality. For a description of valid statement options, see db2_set_option(3). RETURN VALUES
Returns a statement resource if the SQL statement was successfully parsed and prepared by the database server. Returns FALSE if the data- base server returned an error. You can determine which error was returned by calling db2_stmt_error(3) or db2_stmt_errormsg(3). EXAMPLES
Example #1 Preparing and executing an SQL statement with parameter markers The following example prepares an INSERT statement that accepts four parameter markers, then iterates over an array of arrays con- taining the input values to be passed to db2_execute(3). <?php $animals = array( array(0, 'cat', 'Pook', 3.2), array(1, 'dog', 'Peaches', 12.3), array(2, 'horse', 'Smarty', 350.0), ); $insert = 'INSERT INTO animals (id, breed, name, weight) VALUES (?, ?, ?, ?)'; $stmt = db2_prepare($conn, $insert); if ($stmt) { foreach ($animals as $animal) { $result = db2_execute($stmt, $animal); } } ?> SEE ALSO
