I have Influx DB where I store information related jenkins.
when I execute when below query
SELECT
project_name,
build_number,
build_result
FROM (
SELECT
project_name,
build_number,
build_result
FROM
"jenkins_data"
WHERE (
"project_name" =~ /^(?i)(test1|test2)$/ AND
"project_path" =~ /.*(?i)Playground.*$/
)
ORDER BY time DESC
LIMIT 15
)
WHERE (
"build_result" = 'SUCCESS'
)
ORDER BY time DESC
will get the below result
time project_name build_number build_result
1676039543717000000 test1 1600 SUCCESS
1676039352721000000 test1 1792 SUCCESS
1676039283509000000 test2 1669 SUCCESS
1676039543717000000 test1 1600 SUCCESS
1676039352721000000 test1 1792 SUCCESS
1676039283509000000 test2 1669 SUCCESS
1676039543717000000 test1 1600 SUCCESS
1676039352721000000 test1 1792 SUCCESS
1676039283509000000 test2 1669 SUCCESS
1676039283509000000 test2 1669 SUCCESS
the above result is correct
but when use count in my query it gives improper results
SELECT
count(build_number)
FROM (
SELECT
project_name,
build_number,
build_result
FROM
"jenkins_data"
WHERE (
"project_name" =~ /^(?i)(test1|test2)$/ AND
"project_path" =~ /.*(?i)Playground.*$/
)
ORDER BY time DESC
LIMIT 15
)
WHERE (
"build_result" = 'SUCCESS'
)
ORDER BY time DESC
will give result as 15 which is not correct I am doing anything wrong here?
Influxdb version used - InfluxDB v1.8.6 (git: 1.8 v1.8.6)

I could able to solve the issue by adding DISTINCT in count functions.
used below query
SELECT
count(DISTINCT build_number)
FROM (
SELECT
project_name,
build_number,
build_result
FROM
"jenkins_data"
WHERE (
"project_name" =~ /^(?i)(test1|test2)$/ AND
"project_path" =~ /.*(?i)Playground.*$/
)
ORDER BY time DESC
LIMIT 15
)
WHERE (
"build_result" = 'SUCCESS'
)
ORDER BY time DESC
