In my database I have the following table:
Mytable id SERIAL, category VARCHAR, value VARCHAR
And I execute the following query:
select category, COUNT(*) from mytable group by category
What I want is to generate a single row value containing the following:
category1 | category2 | category3 1234 | 3456 | 12345
The table return the following results:
category | Value `category1` | 1234 `category2` | 3456 `category3` | 12345
Do you have any idea how to do this?
I have looked the crosstab function but required an extra column named
row_name that in my cases does not exist. Also using a second query seems like a waste to me.
