[英]SQL total row count
I need to select the number of rows: 我需要选择行数:
select
int_re_usu as Qtd_Respostas
from
tb_questionario_voar_resposta
group by
int_re_usu
It returns: 它返回:
1- 687
2- 375076
3- 339012
4 -314083
5 -52741
6 -339977
7- 276041
8- 373304

19 - 275889

23 -273393
I want to select instead the number 23,which is the total row_count. 我想选择数字23,即总row_count。
Any ideias? 任何想法?
Use @@RowCount 使用@@ RowCount
select int_re_usu as Qtd_Respostas from tb_questionario_voar_resposta group by int_re_usu
Select @@RowCount
OR Use a Derived Table 或使用派生表
Select Count(*) from
(select int_re_usu as Qtd_Respostas from tb_questionario_voar_resposta group by int_re_usu) q1
Instead of GROUP BY, you can use DISTINCT: 您可以使用DISTINCT而不是GROUP BY:
SELECT COUNT(DISTINCT int_re_usu)
FROM tb_questionario_voar_resposta
select count(*) from
( select int_re_usu as Qtd_Respostas from tb_questionario_voar_resposta group by int_re_usu ) as a
You can use the count(*) function. 您可以使用count(*)函数。
select count(*)
from table_name
group by column_name
With temp as
( select int_re_usu as Qtd_Respostas
from tb_questionario_voar_resposta
group by int_re_usu )
Select count(*) from temp
