Query Options and Utilities

Each query execution method allows for the passing of an options struct. This is the same struct you would pass to queryExecute.

Default Options

qb allows you to specify default options when creating the QueryBuilder instance using the defaultOptions argument.

You can set defaultOptions for the default QueryBuilder (QueryBuilder@qb) in your config/ColdBox.cfc file under moduleSettings.

moduleSettings = {
    "qb": {
        "defaultOptions": {
            "timeout": 60
        }
    }
};

You can also combine this with WireBox to create custom QueryBuilder instances pointing to different datasources and even different grammars.

component {

    function afterAspectsLoad() {
        binder.map( "MyCustomQueryBuilder" )
            .to( "qb.models.Query.QueryBuilder" )
            .initArg( name = "grammar", ref = "AutoDiscover@qb" )
            .initArg( name = "defaultOptions", value = {
                "datasource": "my_custom_datasource" 
            } );
    }

}

Retrieving results from alternative datasources

In Application.cfc you can specify your default datasource which will be used by qb. If you want to retrieve data from other datasources you can specify this in all retrieval functions by using the extra options parameter such as:

query.from( "users" )
    .get( options = { datasource: "MyOtherDatasourceName" } );

If you also want to use a non-default SQL Grammar you have to specify this when creating your QueryBuilder.

var query = wirebox.getInstance( "QueryBuilder@qb" )
    .setGrammar( wirebox.getInstance( "SqlServerGrammar@qb" ) );

Replacing or Inlining Bindings

qb can inline the query bindings into the SQL string that it has built up. This is used by other tools like toSQL or dump to provide a richer debugging experience. It is also publicly available for other libraries to use, such as CommandBox Migrations.

replaceBindings

Replace the question marks (?) in a sql string with the bindings provided.
