Hi all,
I have this query:
SELECT tableA.*, COUNT(*) AS Tot
FROM tableB
LEFT JOIN tableA ON tableA.uid=tableB.uid
GROUP BY tableA.uid
This query shows only the users (tableA) that are in tableB with at
least 1 record (like total) but not the users that have 0 record.
How can I obtain all users

I've inverted, like you said, the tables and used LEFT OUTER JOIN:
SELECT tableA. * , COUNT( tableB.uid ) AS Tot
FROM tableA
LEFT OUTER JOIN tableB ON tableB.uid = tableA.uid
GROUP BY tableA.uid
and it works.
I also tried this other:
SELECT tableA.*, COUNT(tableB.uid) AS Tot
FROM
SELECT tableA.*, COUNT(*) AS Tot
FROM tableB
LEFT OUTER JOIN tableA ON tableA.uid=tableB.uid
GROUP BY tableA.uid

Hi
I have this select:
SELECT tab1.field, tab2.field, tab3.field
FROM table
JOIN
JOIN
WHERE tab4.type=b
GROUP BY etc
ORDER BY etc
Now, the tab4 has three fields: id, color, type.
I want to select where type=b and to count all the occurrences of
color in the same query.
Example:
I have a column containing headlines. In this column
there are some duplicates, like this:
---
monsters
headline1
monsters
halloween
monsters
halloween
...
--
How can I get a result like this instead?
HEADLINE | HITS
---
monsters | 3
halloween | 2
select headline, count(*) from headlines_table group by headline;

Run this query as rs1:
select distinct scary_words from monsters_table;
String word;
String query;
Int count;
while rs1.next() {
word = rs1.getString();
// Run this query as rs2
query = 'select count(*) from monster_table where scary_words=' +
word

Run this query as rs1:
select distinct scary_words from monsters_table;
String word;
String query;
Int count;
while rs1.next() {
word = rs1.getString();
// Run this sql query as rs2
query = 'select count(*) from monster_table where scary_words=' +

This is a basic GROUP BY query:
SELECT headline, count(*) hits
FROM headlinetable
GROUP BY headline
ORDER BY hits DESC
