Is it possible to do a join to a nested select statement in SubSonic 2.2? I am having trouble with this because I have to do a group by...
I.E.
select conn_company.company_name, SUM(t.quote_grand_total) as 'SUM' from conn_company
inner join
(SELECT *
FROM [dbo].[QuoteDBAll]
where [dbo].[QuoteDBAll].[quote_status_id] = 1
AND [dbo].[QuoteDBAll].[quote_ca_modified_date] BETWEEN '12/1/2000' AND '12/1/2009'
) t
on conn_company.company_id = t.company_id
group by company_name
having company_name = 'JACK'
Unfortunately you're not going to be able to convert that SQL into SubSonic 2 syntax. I would suggest you create a sql view based on your query and get SubSonic to generate a model from that instead.

Is it possible to use .QueryMultiple (or some other method) in Dapper, and use the results of each former query to be used in the where clause of the next query, without having to do each query individually, get the id, and then .Query again, get the id and so on.
For example,
string sqlString = #"select tableA_id from tableA where tableA_lastname = #lastname;
select tableB_id from tableB WHERE tableB_id = tableA_id";
db.QueryMultiple.(sqlString, new {lastname = "smith"});
Is something like this possible with Dapper or do I need a view or stored procedure to accomplish this? I can use multiple joins for one SQL statement, but in my real query there are 7 joins, and I didn't think I should return 7 objects.
Right now I'm just using object.
You can store every previous query in table parameter and then first perform select from the parameter and query for next, for example:
DECLARE #TableA AS Table(
tableA_id INT
-- ... all other columns you need..
)
INSERT #TableA
SELECT tableA_id
FROM tableA
WHERE tableA_lastname = #lastname
SELECT *
FROM #TableA
SELECT tableB_id
FROM tableB
JOIN tableA ON tableB_id = tableA_id
Can somebody help me in converting below mentioned query in to Maximo's where clause:
select distinct workorder.wonum from workorder inner join [assignment]
On workorder.wonum=[assignment].wonum
inner join amcrew
On amcrew.amcrew=[assignment].amcrew
inner join amcrewlabor
On amcrewlabor.amcrew=amcrew.amcrew
inner join labor
On amcrewlabor.laborcode=labor.laborcode
inner join person
on labor.laborcode=person.personid where amcrewlabor.laborcode='KELLYB'
KELLYB is PERSONID used here for just reference.
If you are using a custom search query in Maximo, you can try prepending your with in (your query)
For example, if you're in Maximo's work order tracking module, the application uses select * from workorder by default. Any time you add a search filter such as work order number (wonum), then the query appends to run a query as select * from workorder where wonum = '123' if 123 is the work order number you entered.
Your where clause might look something like this:
wonum in (
select distinct workorder.wonum
from workorder
join assignment on workorder.wonum=assignment.wonum
join amcrew on amcrew.amcrew=assignment.amcrew
join amcrewlabor on amcrewlabor.amcrew=amcrew.amcrew
join labor on amcrewlabor.laborcode=labor.laborcode
join person on labor.laborcode=person.personid
where amcrewlabor.laborcode='KELLYB'
)
The SQL that is generated in Microsoft Access will not necessarily work in Maximo without some modification.
I searched a lot about sorting elements by sum of votes (in another model), like I do in SQL here :
SELECT item.* FROM item
LEFT JOIN (
SELECT
vote.item,
SUM(vote.value) AS vote.rating
FROM vote
GROUP BY vote.item
) AS res ON item.id = vote.item
ORDER BY res.rating DESC
Is there a way to do it via waterline methods ?
I think you can't do the left join with simple waterline methods, but you can use the .query method to execute your raw SQL syntax.
Sails MySQL adapter makes sum('field') conflict with sort('field'). It will generate SQL query like:
SELECT SUM(table.field) AS field FROM table ORDER BY table.field;
But I want:
SELECT SUM(table.field) AS field FROM table ORDER BY field;
It same as:
SELECT SUM(table.field) AS f FROM table ORDER BY f;
My solution is using lodash.sortBy() to process results. https://lodash.com/docs/4.16.4#sortBy
I want to perform a simple join on two tables (BusinessUnit and UserBusinessUnit), so I can get a list of all BusinessUnits allocated to a given user.
The first attempt works, but there's no override of Select which allows me to restrict the columns returned (I get all columns from both tables):
var db = new KensDB();
SqlQuery query = db.Select
.From<BusinessUnit>()
.InnerJoin<UserBusinessUnit>( BusinessUnitTable.IdColumn, UserBusinessUnitTable.BusinessUnitIdColumn )
.Where( BusinessUnitTable.RecordStatusColumn ).IsEqualTo( 1 )
.And( UserBusinessUnitTable.UserIdColumn ).IsEqualTo( userId );
The second attept allows the column name restriction, but the generated sql contains pluralised table names (?)
SqlQuery query = new Select( new string[] { BusinessUnitTable.IdColumn, BusinessUnitTable.NameColumn } )
.From<BusinessUnit>()
.InnerJoin<UserBusinessUnit>( BusinessUnitTable.IdColumn, UserBusinessUnitTable.BusinessUnitIdColumn )
.Where( BusinessUnitTable.RecordStatusColumn ).IsEqualTo( 1 )
.And( UserBusinessUnitTable.UserIdColumn ).IsEqualTo( userId );
Produces...
SELECT [BusinessUnits].[Id], [BusinessUnits].[Name]
FROM [BusinessUnits]
INNER JOIN [UserBusinessUnits]
ON [BusinessUnits].[Id] = [UserBusinessUnits].[BusinessUnitId]
WHERE [BusinessUnits].[RecordStatus] = #0
AND [UserBusinessUnits].[UserId] = #1
So, two questions:
- How do I restrict the columns returned in method 1?
- Why does method 2 pluralise the column names in the generated SQL (and can I get round this?)
I'm using 3.0.0.3...
So far my experience with 3.0.0.3 suggests that this is not possible yet with the query tool, although it is with version 2.
I think the preferred method (so far) with version 3 is to use a linq query with something like:
var busUnits = from b in BusinessUnit.All()
join u in UserBusinessUnit.All() on b.Id equals u.BusinessUnitId
select b;
I ran into the pluralized table names myself, but it was because I'd only re-run one template after making schema changes.
Once I re-ran all the templates, the plural table names went away.
Try re-running all 4 templates and see if that solves it for you.
I am using version 2.1 of SubSonic. I am trying to build to build a relatively simple query where I get a list of Roles for a User using UserId as a parameter. (UserId is a string...)
SubSonic.SqlQuery sel = new SubSonic.Select().From(Data.Tables.Role).InnerJoin(Data.Tables.UserRole, Data.UserRole.Columns.RoleId, Data.Tables.Role, Data.Role.Columns.Id).InnerJoin(Data.Tables.User, Data.User.Columns.Id, Data.Tables.UserRole, Data.UserRole.Columns.UserId).Where("[dbo].[User].[Id]").IsEqualTo(userId);
this generates the query
SELECT [dbo].[Role].[Id], [dbo].[Role].[PID], [dbo].[Role].[Name]
FROM [dbo].[Role]
INNER JOIN [dbo].[UserRole] ON [dbo].[Role].[Id] = [dbo].[UserRole].[RoleId]
INNER JOIN [dbo].[User] ON [dbo].[UserRole].[UserId] = [dbo].[User].[Id]
WHERE [dbo].[User].[Id] = #[dbo].[User].[Id]0
which fails. If I replace the Where with .Where(Data.User.Columns.Id) this generates the query
SELECT [dbo].[Role].[Id], [dbo].[Role].[PID], [dbo].[Role].[Name]
FROM [dbo].[Role]
INNER JOIN [dbo].[UserRole] ON [dbo].[Role].[Id] = [dbo].[UserRole].[RoleId]
INNER JOIN [dbo].[User] ON [dbo].[UserRole].[UserId] = [dbo].[User].[Id]
WHERE [dbo].[Role].[Id] = #Id0
which uses the Role table in the Where clause instead of the User table.
Is this a bug, or am I doing something incorrectly? What would be the correct way to do this? Thanks.
This is fixed in version 2.2 - I would suggest upgrading.
