#SQL

This might be more of a math problem than a Caché question.
I have a SQL query that joins two tables. I want to assign a unique ID to each row of the product table.

I've mapped multiple tables (UNION on mapped SQL classes) into a view, using CREATE VIEW.

Through ODBC, in Entity Framework, I am querying against that view and offering paging. The paging is implemented using IQueryable.Skip and IQueryable.Take.

Skip seems to have unexpected results, I believe due to incorrect SQL generated by the Entity Framework provider, though perhaps I've done something incorrectly. The generated SQL looks similar to this (with some bits replaced or altered for security reasons), the basic structure is unaltered.

I have a database which needs to be synced to another system and considering to use the SQL Inbound adapter to 'watch' the database. The other system, however, has a bulk API so I'd prefer to send multiple SQL rows in a single message to that system. The SQL Inbound adapter seems to trigger a single call (to a process or business operation) per SQL-row.

select * from A left join B on A.x = B.x inner join C on B.y = C.y

does Cache SQL treat the join path: LEFT_JOIN(A,INNER_JOIN(B.C)) also a valid candidate path?

Thanks.

Hi -

I'm creating a custom report in Health Insight via SQL and one of the requirements says that I must include patients who are >= 13 years old (which is easy) but I also need to include patients who WILL be 13 years old as of December 31st of current year that the report is ran in.

I see that there is an Age column and an AgeInMonths column in HSAA.Patient. and of course a DOB column. I'm wondering if it is possible to do this purely using SQL (and SQL functions) or if I will have to incorporate a COS function to achieve this requirement.

Any suggestions?

Hi, I'm a student, weak programming. I ask for your help, I write a program in C #, there are two tables, but I do not understand how to organize the connection between them many to many. Table in DataGridView1 from DataSet1 on Form1 key connection in DataGridView1 from DataSet1 to Form3

I do this on Form1

Does anyone know how to return the sys.process table with the corresponding configname item for each process? Also, is there a key for the Job Type field?

Any suggestions on the most efficient way to convert yyyymmdd string to mm/dd/yyyy?

I have a Cache-compatible sql script file and each query is separate by white space.

How could I ask Cache to execute all the queries in this file and dump the result to a specified file?

Thanks.

I get two methods below: I would run both methods concurrently.

However, the "testRead" would always read the uncommitted results from "testInsert".

Anyway to avoid that? Thanks.

ClassMethod testInsert()
{
  &sql(START TRANSACTION ISOLATION LEVEL READ COMMITTED, READ WRITE)
  &sql(insert into Test.Table(AttrA,AttrB,AttrC,AttrD) values(1,2,3,4))
  hang 15
  &sql(ROLLBACK)
}

ClassMethod testRead()
{
  &sql(START TRANSACTION ISOLATION LEVEL READ COMMITTED)
  &sql(select count(*) into :ans from Test.Table)
  &sql(COMMIT)
  w !,ans
}

Greetings to all!!! Suppose there is a table Mother (ID, Name) and Child (ID, Name, Mother), Mother in the table Childis a relationship. Let's say the task is to deduce the names of all the children whose their moms' names start with the letter 'A', I can do this in two ways in sql, and I can not understand the difference, the pros and cons that when to use:

Hi,

I have a class with around 400k lines and 60 columns. Class storage is Cache SQL storage (Mapped from a global).

I want to create multiple indices on certain fields.

I am familiar with two approaches:

1. Create a new map (Index type) on a pointer global.

2. Create a bitmap index

Which approach is more recommended to be used in the case I described? If there are any other approaches, I will be happy to hear.

Thanks :)

I have a class that has a list property, which contains a list of other objects, and I want to join against it in SQL.

Class Foo Extends %Persistent
{
Property MyBars As list Of Bar;
}
