Python/SQL - WHERE-Klausel nicht für alle Zeilen

Question

Ich habe ein Problem mit dem folgenden Code in einem Python-Programm, das ich gebaut habe. Das Programm ruft Daten aus einer Datenbank ab und speichert sie in einer Excel-Tabelle basierend auf einer Liste von Referenznummern 'GrantRefNumber', die sie eingeben.

Es funktioniert, aber aus irgendeinem Grund nur die erste Referenznummer hat die 'a.reporting_period_id like 'none-' angewendet, den Rest nicht.

Ich verwende eine Variablensubstitution im SQL-Code, um die Liste der Referenznummern in die Zeichenfolge einzufügen.

Jede Hilfe wäre sehr willkommen!

SQL:

"SELECT a.fa_reference as [GrantRefNumber], 
a.fa_name as [Award Title], 
a.location as [RO], 
ISNULL(cat.grant_department_name, '') as [Department], 
a.funding_start_date as [Start Date], 
a.funding_end_date as [End Date], 
a.[pi] as [PI ID], 
a.pi_initials as [PI Name], 
a.pi_surname as [PI Surname], 
r1_2 as [Type], 

DATEADD(s, cast(last_submitted_date as int), '1970-01-01 00:00:00') as [Submitted Date] 

from keywordagreements a inner join entries_publications p on a.id = 
p.agreement_id left outer join mrc_categories cat on a.origid = cat.id and cat.centre not in ('2') 

where a.[pi] NOT LIKE 'S%' and response_code not like 'Test' and Closed is null 
and a.reporting_period_id like 'none-' 
and a.funding_organisation not like '%UKSA%' and {}' 

Order by [RO], [PI ID], [GrantRefNumber]".format(finalList) 

finalList (variable Substitution):

Die finalList ist eine Liste der Referenznummern, die ich von dem Benutzer in Python erhalten genannte 'Artikel'

items = dfCall['GrantRefNumber'].values.tolist() 
refList = " OR ".join(["a.fa_reference LIKE '%s'" % num for num in items]) 
finalList = refList[:-1] 

Ich verwende PYODBC, um die Daten zu extrahieren.

Der SQL in meinem Code sieht wie folgt aus (ich die Anführungszeichen entfernt (und einige der Spalten) in dem vorherigen Code leichter lesbar zu machen):

stringQ = "SELECT a.fa_reference as [GrantRefNumber], a.fa_name as [Award Title]," \ 
      " a.location as [RO], ISNULL(cat.grant_department_name, '') as [Department]," \

      "ISNULL(r1_2_26, '')" \

Answer 1

Ich bin nicht zu sehen, wo Ihr format Befehl ersetzt. Hier sind ein paar Beispiele für die Format-Befehl:

'This is a {} string.'.format('formatted') 
'This is a {0} {1}.'.format('formatted', 'string') 
'This is a {replace_me} {replace_me_2}.'.format(replace_me='formatted', replace_me_2='string') 

Ausgänge This is a formatted string.

Sie werden ändern müssen Sie SQL finalList in die SQL einzufügen. Da wir nicht den ganzen Code sehen können, auch wie es erscheinen Sie Triple-Zitat Formatierung für Multi-Line-Support verwenden möchte:

sql = """ 
    SELECT * FROM table 
    WHERE blah = '{string_to_compare}' 
""".format(string_to_compare='blah') 

Seien Sie sehr vorsichtig, sind Sie für SQL-Injection zu öffnen, wenn Zeichenfolge mit Substitution in jeder SQL-Abfrage. Viel Glück!

Answer 2

Ok, ich denke, ich habe es behoben. Ich habe die {}' in Klammern, d. H. ({}'), da es die anderen Referenznummern als eine separate Anweisung wegen der OR-Befehl behandelt.
