mysql query to search multiple values in comma separated list with AND clause


By : hafiz
Date : March 29 2020, 07:55 AM
seems to work fine use FIND_IN_SET() -- a builtin function for mysql to search a string inside a CSV.
code :
SELECT  *
FROM    tableName
WHERE   FIND_IN_SET('2', Userdefined01) > 0 AND
        FIND_IN_SET('5', Userdefined01) > 0 

Select Query with IN clause - having duplicate values in IN clause

fixed the issue. Will look into that further The WHERE clause only filters rows. It does not multiply them.
So, if a row matches one condition or all conditions doesn't matter. The row simply is filtered or not filtered.
code :
select count(*)
from employee e join
     (select 121 as e_id union all
      select 234 union all
      select 536 union all
      select 234
     ) matches
     using (e_id);

Passing a list of values from Python to the IN clause of an SQL query

this one helps. As stated in the comment to the other answer, that approach can fail for a variety of reasons. What you really want to do it create an SQL statement with the required number of parameter placeholders and then use the params= parameter of read_sql to supply the values:
code :
x = ['1000000000164774783','1000000000253252111']
placeholders = ','.join('?' for i in range(len(x)))  # '?,?'
sql = "select * from Pretty_Txns where Send_Customer in (%s)" % placeholders
df = pd.read_sql(sql, cnx, params=x)

How to add a WHERE clause to BigQuery Query to find rows where a column value is not in a list of values


By : Johnnie.Lee
Date : March 29 2020, 07:55 AM
I wish this helpful for you I have a table in BigQuery named events that has a column named 'entitlement'. That column can have values such as 'lapb', 'lacf', 'lasg', 'laxy', 'laza' etc. It can also have 'null' or '' or other values that I don't know. It will only have 1 given value per row so it isn't a list of values. So for example, here is some sample data:
code :
#standardSQL
WITH events AS (
  SELECT 'alice' AS name, 'laxy' AS entitlement, '01072017' AS date UNION ALL
  SELECT 'bob', NULL, '01082018' UNION ALL
  SELECT 'charlie', 'lapb', '01092017' UNION ALL
  SELECT 'daniel', 'lacf', '01092017'
)
SELECT *
FROM events
WHERE entitlement NOT IN ('labp', 'lpaf');
+---------+-------------+----------+
| name    | entitlement | date     |
+---------+-------------+----------+
| alice   | laxy        | 01072017 |
| charlie | lapb        | 01092017 |
| daniel  | lacf        | 01092017 |
+---------+-------------+----------+
