By using set option we can insert record to any table. This is an alternate to insert command using value option of adding single record to the table. Here we have to use insert command at the beginning and use field names along with the value for the files with an equal to symbol. This is help full when we are handling more number of fields with one insert command; we can match the value to field name easily without worrying about matching the value to field names. In other words we can ensure proper value to the correct column. This is also useful when we are adding value to some fields and allowing default value for other fields. Here is an example of the sql insert command to add a record using set option.
SQL Insert using VALUE option
This will add one new record to the table and values for two fields book_name and author gets added in the new record. This is quite helpful in matching field names to value.Inserting record with default value or auto-increment fieldIn our student record we already have student id which is auto- increment field hence while adding a record we need no enter its name or value. Other than the auto increment field we can store records to our student table by using set command.
Similarly we need not specify for default value of the fields while adding recordsPHP Script using SET commandWe will add one record to our student table by using SET command and PHP Script.We will first connect to database Here is the complete code
Using MySQLIrequire "config.php";// Database connection $id=50; $name = 'my_name'; $class='Three'; $mark=70; $sex='male'; $query="INSERT INTO student set id=?,name=?,class=?,mark=?,sex=?"; $stmt=$connection->prepare($query); if($stmt){ $stmt->bind_param("issds", $id, $name, $class,$mark,$sex); if($stmt->execute()){ echo "<br>No of records inserted : ".$connection->affected_rows; }else{ echo $connection->error; } }else{ echo $connection->error; } |
