Updates

Of course, in addition to inserting records into the database, the query builder can also update existing records using the update method. The update method, like the insert method, accepts an array of column and value pairs containing the columns to be updated. You may constrain the update query using where clauses:

//qb
var addRecords = query.from( "users" )
    .whereID( 10 )
    .update(  { "name" = "Roberto", "email" = "[email protected]", "age" = 55 });
writeDump(addRecords);

//sql
UPDATE `users` SET `age` = 55, `email` = `[email protected]`, `name` = `Roberto` WHERE `ID` = 10

You can also use Expressions inside an update statement:

query.from( "posts" )
    .whereID( 10 )
    .update( { "likes" = query.raw( "likes + 1" ) } );
    
// SQL:      UPDATE `posts` SET `likes` = likes + 1 WHERE `ID` = ?
// Bindings: [ 10 ]

Updating Null values

Null values can be inserted by using queryparam syntax:

query.from("user")
		.whereId( 10 )
		.update( {
			manager_FK = { value = "", null=true },
		} )

if you are using Lucee with full null support the following (easier) syntax is also allowed:

query.from("user")
		.whereId( 10 )
		.update( {
			manager_FK = { value = null },
		} )
