MAXDB_STMT_BIND_PARAM(3) 1 MAXDB_STMT_BIND_PARAM(3) maxdb_stmt_bind_param - Binds variables to a prepared statement as parameters Procedural style SYNOPSIS
bool maxdb_stmt_bind_param (resource $stmt, string $types, mixed &$var1, [mixed &$...]) DESCRIPTION
Object oriented style bool maxdb_stmt::bind_param (string $types, mixed &$var1, [mixed &$...]) Procedural style (extended syntax): bool maxdb_stmt_bind_param (resource $stmt, string $types, array &$var) Object oriented style (extended syntax): bool maxdb_stmt::bind_param (string $types, array &$var) maxdb_stmt_bind_param(3) is used to bind variables for the parameter markers in the SQL statement that was passed to maxdb_prepare(3). The string $types contains one or more characters which specify the types for the corresponding bind variables. The extended syntax of maxdb_stmt_bind_param(3) allows to give the parameters as an array instead of a variable list of PHP variables to the function. If the array variable has not been used before calling maxdb_stmt_bind_param(3), it has to be initialized as an emtpy array. See the examples how to use maxdb_stmt_bind_param(3) with extended syntax. Variables for SELECT INTO SQL statements can also be bound using maxdb_stmt_bind_param(3). Parameters for database procedures can be bound using maxdb_stmt_bind_param(3). See the examples how to use maxdb_stmt_bind_param(3) in this cases. If a variable bound as INTO variable to an SQL statement was used before, the content of this variable is overwritten by the data of the SELECT INTO statement. A reference to this variable will be invalid after a call to maxdb_stmt_bind_param(3). For INOUT parameters of database procedures the content of the bound INOUT variable is overwritten by the output value of the database procedure. A reference to this variable will be invalid after a call to maxdb_stmt_bind_param(3). Type specification chars +----------+---------------------------------------------------+ |Character | | | | | | | Description | | | | +----------+---------------------------------------------------+ | i | | | | | | | corresponding variable has type integer | | | | | d | | | | | | | corresponding variable has type double | | | | | s | | | | | | | corresponding variable has type string | | | | | b | | | | | | | corresponding variable is a blob and will be sent | | | in packages | | | | +----------+---------------------------------------------------+ 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(); } $maxdb->query ("CREATE TABLE temp.mycity LIKE hotel.city"); $maxdb->query ("INSERT INTO temp.mycity SELECT * FROM hotel.city"); $stmt = $maxdb->prepare("INSERT INTO temp.mycity VALUES (?, ?, ?)"); $stmt->bind_param('sss', $zip, $name, $state); $zip = '11111'; $name = 'Georgetown'; $state = 'NY'; /* execute prepared statement */ $stmt->execute(); printf("%d Row inserted. ", $stmt->affected_rows); /* close statement and connection */ $stmt->close(); /* Clean up table CountryLanguage */ $maxdb->query("DELETE FROM temp.mycity WHERE name='Georgetown'"); printf("%d Row deleted. ", $maxdb->affected_rows); /* close connection */ $maxdb->close(); ?> Example #2 Procedural style <?php $link = maxdb_connect("localhost", "MONA", "RED", "DEMODB"); /* check connection */ if (!$link) { printf("Connect failed: %s ", maxdb_connect_error()); exit(); } maxdb_query ($link, "CREATE TABLE temp.mycity LIKE hotel.city"); maxdb_query ($link, "INSERT INTO temp.mycity SELECT * FROM hotel.city"); $stmt = maxdb_prepare($link, "INSERT INTO temp.mycity VALUES (?, ?, ?)"); maxdb_stmt_bind_param($stmt, 'sss', $zip, $name, $state); $zip = '11111'; $name = 'Georgetown'; $state = 'NY'; /* execute prepared statement */ maxdb_stmt_execute($stmt); printf("%d Row inserted. ", maxdb_stmt_affected_rows($stmt)); /* close statement and connection */ maxdb_stmt_close($stmt); /* Clean up table CountryLanguage */ maxdb_query($link, "DELETE FROM temp.mycity WHERE name='Georgetown'"); printf("%d Row deleted. ", maxdb_affected_rows($link)); /* close connection */ maxdb_close($link); ?> The above example will output something similar to: 1 Row inserted. 1 Row deleted. Example #3 Procedural style (SELECT INTO) <?php $link = maxdb_connect("localhost", "MONA", "RED", "DEMODB"); /* check connection */ if (!$link) { printf("Connect failed: %s ", maxdb_connect_error()); exit(); } /* Performing SQL query */ $stmt = maxdb_prepare ($link, "SELECT price INTO ? FROM hotel.room where hno = ? and type = ?"); if (!$stmt) { printf ("Prepare failed: %s ", maxdb_error($link)); } $hno = "50"; $rtype = "suite"; maxdb_stmt_bind_param($stmt, 'dss', $price, $hno, $rtype); maxdb_stmt_execute($stmt); printf ("%f ", $price); maxdb_stmt_close ($stmt); ?> The above example will output something similar to: 21.600000 Example #4 Procedural style (DB procedure) <?php $link = maxdb_connect("localhost", "MONA", "RED", "DEMODB"); /* check connection */ if (!$link) { printf("Connect failed: %s ", maxdb_connect_error()); exit(); } maxdb_report (MAXDB_REPORT_OFF); maxdb_query($link,"DROP DBPROC test_proc"); maxdb_report (MAXDB_REPORT_ERROR); $query = "create dbproc test_proc (INOUT e_text char(72)) AS select * from SYSDBA.DUAL; fetch into :e_text;"; maxdb_query($link, $query); /* Performing SQL query */ $stmt = maxdb_prepare ($link, "CALL test_proc (?)"); if (!$stmt) { printf ("Prepare failed: %s ", maxdb_error($link)); } maxdb_stmt_bind_param($stmt, 's', $result); maxdb_stmt_execute($stmt); printf ("%s ", $result); maxdb_stmt_close ($stmt); ?> The above example will output something similar to: a Example #5 Object oriented style (extended syntax) <?php $maxdb = new maxdb('localhost', 'MONA', 'RED', 'DEMODB'); /* check connection */ if (maxdb_connect_errno()) { printf("Connect failed: %s ", maxdb_connect_error()); exit(); } $maxdb->query ("CREATE TABLE temp.mycity LIKE hotel.city"); $maxdb->query ("INSERT INTO temp.mycity SELECT * FROM hotel.city"); $stmt = $maxdb->prepare("INSERT INTO temp.mycity VALUES (?, ?, ?)"); $arr = array(); $stmt->bind_param('iss', $arr); $arr[0] = 11111; $arr[1] = 'Georgetown'; $arr[2] = 'NY'; /* execute prepared statement */ $stmt->execute(); printf("%d Row inserted. ", maxdb_stmt_affected_rows($stmt)); $arr[0] = 22222; $arr[1] = 'New Orleans'; $arr[2] = 'LA'; /* execute prepared statement */ $stmt->execute(); printf("%d Row inserted. ", $stmt->affected_rows); /* close statement and connection */ $stmt->close(); $result = $maxdb->query("SELECT * from temp.mycity WHERE zip = '11111' OR zip = '22222'"); if ($result) { while ($row = $result->fetch_row()) { printf ("%s %s %s ", $row[0], $row[1], $row[2]); } } /* Clean up table CountryLanguage */ $maxdb->query("DELETE FROM temp.mycity WHERE name='Georgetown'"); $maxdb->query("DELETE FROM temp.mycity WHERE name='New Orleans'"); printf("%d Rows deleted. ", $maxdb->affected_rows); /* close connection */ $maxdb->close(); ?> The above example will output something similar to: 1 Row inserted. 1 Row inserted. 11111 Georgetown NY 22222 New Orleans LA 2 Rows deleted.
