Derivando campos a partir de campos do tipo grade
Um campo do tipo grade pode ser usado como lookup de um campo no filtro de uma consulta.
Exemplo:
var iq = new IQuery();
iq.uncheckPermission();
iq = iq.from(-1891168937)
.where([{
field: 'GRIDDETALHE.AUXILIAR',
operator: '=',
value: 0
}])
.column('*');
SQL gerado:
select *
from master master1
where (
exists (
select 1 from Detalhe Detalhe2
where (Detalhe2.mestre = master1.ikey and Detalhe2.AUXILIAR = 0)
and (( Detalhe2.iClass in (-1891168945)))
)
)

Personalizando um "group by"
Em algumas situações, é necessário que a cláusula “group by” seja personalizada. Neste caso é possível indicar a API para ignorar o group by gerado automaticamente e para que seja utilizado um personalizado. Para isto, utiliza-se o método groupBy conforme exemplo abaixo:
var IQuery = require('@nginstack/iquery/lib/IQuery');
var alocacaoMaior = IQuery.from(-1895833131 /* Requisitos num Sprint */);
alocacaoMaior = alocacaoMaior.where( [ { field: "SPRINT", operator: "=", value: 3454359 } ] )
alocacaoMaior = alocacaoMaior.groupBy( [ { field: "TAREFA"} ] )
var alocacao = IQuery.from(-1895833131 /* Requisitos num Sprint */);
alocacao = alocacao.where(
[
{
field: "CHAVE",
operator: "=",
value: alocacaoMaior.column([{
literal: "CAST(SUBSTR( max(" +
"CAST(EXTRACT( year from INICIO ) as char(4) ) || " +
"SUBSTR('00' || CAST(EXTRACT( month from INICIO ) as char(2) ), CHAR_LENGTH('00' || " +
"CAST( EXTRACT( month from INICIO ) as varchar(2) )) - 1, 2 ) || " +
"SUBSTR('00' || CAST( EXTRACT( day from INICIO ) as char(2) ), CHAR_LENGTH('00' || " +
"CAST( EXTRACT( day from INICIO ) as varchar(2) )) - 1, 2 ) || " +
"SUBSTR('00000000000000000000' || CAST(CHAVE as varchar(20) ), " +
"CHAR_LENGTH('00000000000000000000' || CAST(CHAVE as varchar(20) )) - 19, 20 ) ), 9, 20) as BIGINT) as CHAVE"
}])
}
]);
alocacao = alocacao.column( [ { field: "CHAVE"}, { field: "INICIO"}, { field: "TAREFA"} ] )
alocacao.toSql();
Irá gerar o sql abaixo:
SELECT chave,
inicio,
sprint,
tarefa
FROM vinculamovimentac
WHERE chave IN (SELECT CAST(SUBSTR(Max(CAST(EXTRACT(year FROM inicio) AS CHAR(4
))
|| SUBSTR('00'

,
CHAR_LENGTH('00'

AND sprint = 3454359

Gerando instruções EXISTS e NOT EXISTS
Suponhamos que você desejar obter todos os pedidos ou baixas que não tenham acessórios. Você deverá usar o IQuery da forma abaixo codificada:
includeOnce -1897036629 //IQuery.ijs
var pedidos = IQuery.from(-2008879000 /* Pedidos ou Provisões */)
var vinculosAcessorios = IQuery.from(-1897051125 /* Vínculos entre Pedidos e Acessórios */)
.where(
{
field: "CRPEDIDO",
operator: "=",
value: pedidos.column({field: "CHCRIACAO", isSubQuery: false})
}
)
var pedidos = pedidos.where({notExists: vinculosAcessorios})
.column({field: "CHAVE"})
pedidos.toSql()
Há dois pontos importantes a serem destacados na API. O primeiro é o uso da propriedade isSubQuery em
pedidos.column({field: "CHCRIACAO", isSubQuery: false}).
Esta propriedade visa mudar o comportamento padrão do iQuery de gerar sub-queries quando uma cláusula Select é passada na propriedade value de uma cláusula Where. Neste caso específico, essa linha irá gerar um SQL semelhante a:
VINCULAMOVIMENTAC2.CRPEDIDO = PEDIDO1.CHCRIACAO
Se a propriedade isSubQuery não tivesse sido desligada, o SQL gerado seria algo assim:
VINCULAMOVIMENTAC2.CRPEDIDO in (select PEDIDO1.CHCRIACAO
from PEDIDO PEDIDO1
where (
(PEDIDO1.CLASSE in (
-2008879000,38292040,38530826,40035178, ...))))
O segundo ponto que merece destaque é o uso de fato do recurso. Note que o objeto passado para a propriedade notExists é uma instância do objeto iQuery.
O SQL completo gerado pelo primeiro código apresentado neste post é semelhante ao código abaixo:
select PEDIDO1.CHAVE
from PEDIDO PEDIDO1
where
(
exists
(
select 1
from VINCULAMOVIMENTAC VINCULAMOVIMENTAC2
where
(
VINCULAMOVIMENTAC2.CRPEDIDO = PEDIDO1.CHCRIACAO

Gerando colunas com valores literais
A API do iQuery foi alterada para passar a suportar colunas com valores literais. Os valores literais são bastante úteis para casos em que o desenvolvedor deseje construir expressões de colunas calculadas.
Exemplo do uso de um literal simples:
includeOnce -1897036629 //IQuery.ijs
var iquery = IQuery.from(-2008879000 /* Pedidos ou provisões */)
.where({field: "CHAVE", operator: "=", value: -1})
.column({literal: "100"})
iquery.toSql()
SQL gerado:
select 100 //Este é o literal gerado

Note que, caso o desenvolvedor queira mudar a precedência dos operadores da expressão, ele deve usar . Exemplificando melhor:
No caso da expressão 2*(QUANTIDADE + 100) a precedência foi mudada para que a soma fosse executada antes da multiplicação.

Desabilitando o filtro por classes filhas nas cláusulas where de classe
A propriedade disableGetChildren permite definir se as chaves das classes filhas da classe informada para o iQuery serão adicionadas a cláusula ‘WHERE’ da query gerada. Por padrão a propriedade está definida como ‘false’ e não precisa ser incluída na chamada do método where.
O exemplo abaixo por ser executado no iDBSql para efeito de testes:
includeOnce -1897036629 //IQuery.ijs
var iquery = IQuery.from( -2007890000 )
.where({field: "CLASSE", operator: "=", value: -2007890000, disableGetChildren: false})

OBS.: É comum usar o iQuery dentro do DataSource, onde existem os métodos
DataSourceFilters.prototype.getIQueryFilters
e DataSourceColumns.prototype.getIQueryColumns.
Estes métodos retornam, respectivamente, um vetor de filtros e colunas no formado do iQuery.
Segue abaixo um exemplo do uso de Joins com vetores de filtros e colunas:
includeOnce -1897036629 //IQuery.ijs
var colunasPedidos = [{field: "CHCRIACAO"}]
// Array que pode ser gerado pelo this.getIQueryColumns do DataSource
var colunasTitulos = [{field: "VALOR"}]
// Array que pode ser gerado pelo this.getIQueryColumns do DataSource.
var titulo = IQuery.from( -2008889000 /* Títulos */ )
IQuery.from( -2008879000 /* Pedidos ou Provisões */ )
.leftOuterJoin( titulo )
.on( { field: "CHCRIACAO", operator: "=", value: titulo.column("CHCRIACAO") } )
.column(colunasPedidos)
.column(titulo.column(colunasTitulos))
