Use And in Waterline

问题

This is my query using waterline

   var queryObject = {
        where: {
          or: [
            {firstName: {'contains': search}},
            {lastName: {'contains': search}},
            {email: {'contains': search}},

          ],
          and: [
            {authType:'google'},
            {dealershipcompany: 11}
          ]
        }
      }

yet adding 'and' return an error:

How do I use AND in waterline correctly, and it is obvious that sails-mysql support 'and', yet I don't know what causes the error, 'or' works perfectly without a problem and I can't chain where, because waterline only bring me the result of the last where.

I'm using Sails v10.4 and sails-mysql v0.11.2 and the query that I want to use it is the following :

SELECT * FROM user where (firstName LIKE '%search%' OR lastName LIKE '%search%' OR email LIKE '%search%') AND (authType='google' OR dealershipcompany = 11);

it returns the result where people have authType of google or with dealership company number 11

回答1:

You don't have to explicitly specify and, as waterline will exactly* match what you include as a normal key pair (waterline docs)

This should do the trick:

   var queryObject = {
    where: {
      or: [
        {firstName: {'contains': search}},
        {lastName: {'contains': search}},
        {email: {'contains': search}},

      ],
      authType: 'google',
      dealershipcompany: 11
    }
  }

That will match records where authType is exactly 'google' and dealership company is exactly 11 and then match anything in or.

*I believe waterline queries are case-insensitive.

Edit: removed errant {}

回答2:

I reached here looking for between in Waterline. Useful for range queries.

The snippet below works. Should also work for other criteria modifiers.

userId: { '<=': 100, '>': 10 }

The following modifiers are available to use when building queries.

'<' / 'lessThan'
'<=' / 'lessThanOrEqual'
'>' / 'greaterThan'
'>=' / 'greaterThanOrEqual'
'!' / 'not'
'like'
'contains'
'startsWith'
'endsWith'
