I have a function that gets a SQL code and inserts a count field in it and executes the query to return the number of rows in it. The objective is to have a dynamic SQL code and be able to get its record count no matter what code it has, because I use it in a registry filter window and I never know what code may be generated, because the user can add as many filters as he/she wants.
But as I use the group by clause, the result is wrong because it is counting the number of times a main registry appears because of the use on many join connections.
The result of that code above should only one row with a columns with 10 as result, but I get a new table with the first columns with a 2 in the first row and a 1 on the other rows.
If I take off the group by clause I will receive a 11 as a count result, but the first row will be counted twice.
What should I do to get a single row and the correct number?
SELECT
COUNT(*) QUERYRECORDCOUNT, // this line appears only in the Count() function
ARTISTA.*,
CATEGORIA.NOME AS CATEGORIA,
ATIVIDADE.NOME AS ATIVIDADE,
LOCALIDADE.NOME AS CIDADE,
MATRICULA.NUMERO AS MAP
FROM
ARTISTA
LEFT JOIN PERFIL ON PERFIL.REGISTRO = ARTISTA.ARTISTA_ID
LEFT JOIN CATEGORIA ON CATEGORIA.CATEGORIA_ID = PERFIL.CATEGORIA
LEFT JOIN ATIVIDADE ON ATIVIDADE.ATIVIDADE_ID = PERFIL.ATIVIDADE
LEFT JOIN LOCALIDADE ON LOCALIDADE.LOCALIDADE_ID = ARTISTA.LOCAL_ATIV_CIDADE
LEFT JOIN MATRICULA ON MATRICULA.REGISTRO = ARTISTA.ARTISTA_ID
WHERE
((ARTISTA.SIT_PERFIL <> 'NORMAL') AND (ARTISTA.SIT_PERFIL <> 'PRIVADO'))
GROUP BY
ARTISTA.ARTISTA_ID
ORDER BY
ARTISTA.ARTISTA_ID;
This always gives you the number of rows for any query you have:
Select count(*) as rowcount from

Paste your query here
