maxdb_stmt_prepare
MAXDB_STMT_PREPARE(3) 1 MAXDB_STMT_PREPARE(3)maxdb_stmt_prepare - Prepare an SQL statement for execution
Procedural style
SYNOPSIS
bool maxdb_stmt_prepare (resource $stmt, string $query)
DESCRIPTION
Object oriented style
mixed maxdb_stmt::prepare (string $query)
maxdb_stmt_prepare(3) prepares the SQL query pointed to by the null-terminated string query. The statement resource has to be allocated by
maxdb_stmt_init(3). The query must consist of a single SQL statement.
Note
You should not add a terminating semicolon or g to the statement.
The parameter $query can include one or more parameter markers in the SQL statement by embedding question mark ( ?) characters at the
appropriate positions.
Note
The markers are legal only in certain places in SQL statements. For example, they are allowed in the VALUES() list of an INSERT
statement (to specify column values for a row), or in a comparison with a column in a WHERE clause to specify a comparison value.
However, they are not allowed for identifiers (such as table or column names), in the select list that names the columns to be
returned by a SELECT statement), or to specify both operands of a binary operator such as the = equal sign. The latter restriction
is necessary because it would be impossible to determine the parameter type. In general, parameters are legal only in Data Manipula-
tion Languange (DML) statements, and not in Data Defination Language (DDL) statements.
The parameter markers must be bound to application variables using maxdb_stmt_bind_param(3) and/or maxdb_stmt_bind_result(3) before exe-
cuting the statement or fetching rows.
RETURN VALUES
Returns TRUE on success or FALSE on failure.
EXAMPLES
Example #1
Object oriented style
<?php
$maxdb = new maxdb("localhost", "MONA", "RED", "DEMODB");
/* check connection */
if (maxdb_connect_errno()) {
printf("Connect failed: %s
", maxdb_connect_error());
exit();
}
$city = "Portland";
/* create a prepared statement */
$stmt = $maxdb->stmt_init();
if ($stmt->prepare("SELECT state FROM hotel.city WHERE name=?")) {
/* bind parameters for markers */
$stmt->bind_param("s", $city);
/* execute query */
$stmt->execute();
/* bind result variables */
$stmt->bind_result($district);
/* fetch value */
$stmt->fetch();
printf("%s is in district %s
", $city, $district);
/* close statement */
$stmt->close();
}
/* close connection */
$maxdb->close();
?>
Example #2
Procedural style
<?php
$link = maxdb_connect("localhost", "MONA", "RED", "DEMODB");
/* check connection */
if (maxdb_connect_errno()) {
printf("Connect failed: %s
", maxdb_connect_error());
exit();
}
$city = "Portland";
/* create a prepared statement */
$stmt = maxdb_stmt_init($link);
if (maxdb_stmt_prepare($stmt, "SELECT state FROM hotel.city WHERE name=?")) {
/* bind parameters for markers */
maxdb_stmt_bind_param($stmt, "s", $city);
/* execute query */
maxdb_stmt_execute($stmt);
/* bind result variables */
maxdb_stmt_bind_result($stmt, $district);
/* fetch value */
maxdb_stmt_fetch($stmt);
printf("%s is in district %s
", $city, $district);
/* close statement */
maxdb_stmt_close($stmt);
}
/* close connection */
maxdb_close($link);
?>
The above example will output something similar to:
Portland is in district OR
