Knex: Conditional queries

Created on 23 Nov 2015  ·  3Comments  ·  Source: knex/knex

Hi,
I don't know if this request exists. But I search a way to build a select query with conditional arguments.
Sample:

knex('mytable')
.select('champ1','champ2','champ3')
.where ('champ1','=',val1)
.andWhere ('champ2','=',val2)
.then{function(rows,err){
})

etc...

But if champ2 is empty or don't fill the condition
I must duplicate the code without the andWhere 

knex('mytable')
.select('champ1','champ2','champ3')
.where ('champ1','=',val1)
.then{function(rows,err){
etc...
})

If i give as value2 :'*', the query turn off.
If you a reference, thanks.
Franck
