Aggregate without join issue #2529

Open DVBI opened this topic on on Jan 10 - 10 comments

I have to prepare the query using query builder where I can display only the number records.

For Example, I just want to display the number of users from the user table.

KoolReport commented on Jan 10

Use this query:

DB::table("users")->count()

How it is possible using the query builder? It is applying the group by default to the query

Example:

I have a salary table and I want to find the total paid salary using query builder only then Query builder is by default applying group by of primary key of table

Sorry that I have not fully understood your inquiry so could you please write me a simple normal SQL query. I will change it to querybuilder.

DVBI commented on Jan 10

select count(*) from users;

KoolReport commented on Jan 10

It is exactly the my query above using querybuider:

DB::table("users")->count()

Ok, it's not very convenient at the moment but you could follow these steps to select count any field of a table with VisualQuery:

1 . In Tables tab: Add a table, select all of its fields.

2 . In Groups tab: Add a group count of the field you want, (no option for count() yet, but count(any field) gets the same result as count()).

3 . Back to Tables tab, deselect all fields.

4 . Click Submit, the query you would get is: "Select count(field1) from table1".

What is the permanent solution?

VisualQuery will be improved in the future so that there will be less steps to build your query. Rgds,
