With formid : 1
With FieldValue : Paul

With FielValue : Bern

My problem how to make my request phpMyAdmin with multiple select?

Answer 1

It looks like your data is a bit over-normalized, with a separate row for each field. I thnk the best way to access this data is by aggregation, assuming that field names are not repeated for any formid:

select formid, submissionId,
       max(case when fieldName = 'FullName' then fieldvalue end) as FullName,
       max(case when fieldName = 'Date' then fieldvalue end) as DateStr,
       max(case when fieldName = 'ville' then fieldValue end) as Ville
from t
where formid = 1
group by SubmissionId

If you want to select the information on a filter, then try:

select *
from (select formid, submissionId,
             max(case when fieldName = 'FullName' then fieldvalue end) as FullName,
             max(case when fieldName = 'Date' then fieldvalue end) as DateStr,
             max(case when fieldName = 'ville' then fieldValue end) as Ville
      from t
      group by SubmissionId
     ) t
 where formid = 1 and FullName = 'Paul' and DateStr = '01/10/2013' and Ville = 'Bern'
