Обсуждение: Inserting variable into

Hello,

I'd like to use a variable for 'Big Company' (e.g. account) or where = statements generally in my cur.execute
statements:

cur.execute("SELECT SUM(revusd) FROM sfdc where saccount = 'Big Company' AND stage LIKE 'Commit%';")
commitd1 = cur.fetchone()
conn.commit()

but I don't know the proper syntax with the cur.execute statement to use a variable.

I imagine others do  - thanks!

Best,

Hagen

So if I understand this correctly my new cur.execute would read:

account = 'JPMC'

 cur.execute("SELECT SUM(revusd) FROM sfdc where saccount = %s AND stage LIKE 'Commit%';",(account ))

and that would translate to

cur.execute("SELECT SUM(revusd) FROM sfdc where saccount = 'JPMC' AND stage LIKE 'Commit%';")

is that right?



Note You can use a Python list as the argument of the IN operator using the PostgreSQL ANY operator.
ids = [10, 20, 30]
cur.execute("SELECT * FROM data WHERE id = ANY(%s);", (ids,))
Furthermore ANY can also work with empty lists, whereas IN () is a SQL syntax error.

Since you are using a tuple this (account ) would need to be (account,) 
per the docs at link previously posted:

"For positional variables binding, the second argument must always be a 
sequence, even if it contains a single variable (remember that Python 
requires a comma to create a single element tuple):"

Hello,

I finally got around to trying to implement this code and I am running into an "IndexError: tuple index out of range" problem.

I am running a function with parameters from a list:

def def_acct_analysis(sht,acct):    print(param[par][0])    print(param[par][1])    sheet = "sheet"+str(sht)    print(sheet)    account = acct    print(account)

par = 0
param = [(1,'ACCT0'),(2,'ACCT1'),(3,'ACCT2'),]

for p in param:    def_acct_analysis(param[par][0], param[par][1])
    par += 1

#Print statements above output:

1
ACCT0
sheet1
ACCT0

cur.execute("SELECT COALESCE(SUM(revusd),0) FROM sfdc where stage LIKE 'Win%' AND saccount = %s", (account,))
wind1 = cur.fetchone()
conn.commit()

Traceback (most recent call last):
  File "/home/datasundae/PycharmProjects/Registration_Reports/sfdc_Account_Tab_Analysis_Function.py", line 333, in <module>
    def_acct_analysis(param[par][0], param[par][1])
  File "/home/datasundae/PycharmProjects/Registration_Reports/sfdc_Account_Tab_Analysis_Function.py", line 96, in def_acct_analysis
    cur.execute("SELECT COALESCE(SUM(revusd),0) FROM sfdc where stage LIKE 'Win%' AND saccount = %s", (account,))
IndexError: tuple index out of range

You have to escape the percent in the like as %%.

FYI, the above can be simplified to:

param = [(1,'ACCT0'),(2,'ACCT1'),(3,'ACCT2'),]

for p in param:
     def_acct_analysis(p[0], p[1])
