How to add quotes around items in a List.

deleted-user-yC5VkbyXzrQR — Sat, 11 Dec 2021 10:51:48 GMT

How do I put quotes around the items in the variable ?

b = ['23','25']
a = ['003','030']


sql = "{} IN ({}) AND {} IN ({})".format("STATE_CODE",", ".join([str(m) for m in b]), "CNTY_CODE", ", ".join([str(n) for n in a]))
‍‍‍‍‍

It will spit out something like this

'STATE_CODE IN (23, 25) AND CNTY_CODE IN (003, 030)'

I need the quotes around the numbers. mapping.DefintionQuery does not like the zeros for some reason. I believe its because there's no quotes around the number.

So I need it to look like below.

SQL = "STATE_CODE IN ('23', '25') AND CNTY_CODE IN ('003', '030')"

Thanks

like this?

sql = "{} IN ({}) AND {!s:} IN ({!s:})".format("STATE_CODE", b, "CNTY_CODE",  a)

sql
"STATE_CODE IN (['23', '25']) AND CNTY_CODE IN (['003', '030'])"‍‍‍‍

or like this?

sql = "{} IN ('{}', '{}') AND {} IN ('{}', '{}')".format("STATE_CODE", *b, "CNTY_CODE",  *a)

sql
"STATE_CODE IN ('23', '25') AND CNTY_CODE IN ('003', '030')"‍‍‍‍‍‍‍‍

or perhaps specify what the string should look like when complete

Hey Dan thanks for the reply.

The problem with the first one is that the SQL expression doesn't like the [ ] brackets around the results. Could i do a remove "[" "]" from the string or something like that. ?

The problem with the second one is that, the list can have more than 2 variables, it can have say from 1 - 15. So the list length will change each time.

"or perhaps specify what the string should look like when complete "I'm not sure how to do this.

tuple your list

b = ['23','25', '27', '29']
a = ['003','030', '300']

sql = "{} IN {} AND {!s:} IN {!s:}".format("STATE_CODE", tuple(b), "CNTY_CODE",  tuple(a))

sql

 "STATE_CODE IN ('23', '25', '27', '29') AND CNTY_CODE IN ('003', '030', '300')"‍‍‍‍‍‍‍‍

Hey Dan thanks for the help. We ended up with a script like below. I realized that the SQL query was not right doing it the above way.

li2 = [['40', '153'],
 ['40', '043'],
 ['40', '003'],
 ['40', '093'],
 ['40', '151'],
 ['40', '047'],
 ['40', '011'],
 ['50', '073'],
 ['50', '099']]
lst_fips = li2

length = len(lst_fips)-1
output = ""
#iterate through list and format output
index = 0 
for i,j in lst_fips:   
    state_code = '(\''+ str(i) +'\')'
    county_code = '(\'' + str(j) + '\')'
    sql = "(STATE_CODE IN {} AND CNTY_CODE IN {})"
    if index < length:
        output = output + sql.format(state_code, county_code) + " OR "
        index += 1
    else:
        output = output + sql.format(state_code, county_code)


print (output) 
(STATE_CODE IN ('40') AND CNTY_CODE IN ('153')) OR (STATE_CODE IN ('40') AND CNTY_CODE IN ('043')) OR (STATE_CODE IN ('40') AND CNTY_CODE IN ('003')) OR (STATE_CODE IN ('40') AND CNTY_CODE IN ('093')) OR (STATE_CODE IN ('40') AND CNTY_CODE IN ('151')) OR (STATE_CODE IN ('40') AND CNTY_CODE IN ('047')) OR (STATE_CODE IN ('40') AND CNTY_CODE IN ('011')) OR (STATE_CODE IN ('50') AND CNTY_CODE IN ('073')) OR (STATE_CODE IN ('50') AND CNTY_CODE IN ('099'))‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

sounds like you should add a query field (eg. STATE_CNTY) and concatenate the state code and county code (eg. '40_153'), then use that field for your queries if you have to do it often.

Yeah I've been trying to get that fips field in there for a while now.

Unless you restructure your data, as Dan suggests, the performance of your query will be poor. Since performance is already out the window, I suggest a different approach than building a series of massive AND OR statements:

>>> fips_fields = [
...     'STATE_CODE',
...     'CNTY_CODE'
... ]
>>>
>>> fips_values = [
...     ['40', '153'],
...     ['40', '043'],
...     ['40', '003'],
...     ['40', '093'],
...     ['40', '151'],
...     ['40', '047'],
...     ['40', '011'],
...     ['50', '073'],
...     ['50', '099']
... ]
>>>
>>> sql_fields = "CONCAT({})".format(", ".join(field for field in fips_fields))
>>> sql_values = "('{})'".format("', '".join("".join(i) for i in fips_values))
>>> sql = "{} IN {}".format(sql_fields, sql_values)
>>>
>>> print(sql)
CONCAT(STATE_CODE, CNTY_CODE) IN ('40153', '40043', '40003', '40093', '40151', '40047', '40011', '50073', '50099)'
>>> ‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

The above assumes STATE_CODE and CNTY_CODE are already TEXT fields; otherwise, you will have to add in CAST operators to cast numbers to text.
