SQL request with list is not iterated in python

Question

i have a list that a created after executing the sql request:

for w in ws.iter_rows (min_row = 1, min_col = 1, max_col = 1):
               
 for cell in w:
      termowner = cell.value
      zinput.append(str(termowner))

The list consists of values that i need to use in next sql query, but some reason the query is not iterate, so i get sql query result consists of a single value:

for j in range(len(zinput)):
 print(j,zinput[j])
 print(counter)

 cursor.execute ("select phone_number from clients where clients_id = ?",zinput[j])

Pls, does anyone know how to solve the problem.

The whole code:

zinput=[]

for w in ws.iter_rows (min_row = 1, min_col = 1, max_col = 1):

 for cell in w:
      termowner = cell.value
      zinput.append(str(termowner))
                

print(zinput) counter = 0

for j in range(len(zinput)): print(j,zinput[j]) print(counter)

 cursor.execute ("select phone_number from clients where clients_id = ?",zinput[j])
        
 results = cursor.fetchall()
 counter +=1
 print(results)
 print('iter',counter, 'done')
