Folks,
Can you please advise on following.
I am trying to display values in native format - Cyrillic.
Below is my query
db.session.query(items.item_name).join(item_ship, item_ship.item_id == items.id).join(house_shipment, house_shipment.id == item_ship.shipment_id).first();
Result: (u'\u041c\u0443\u0436\u0441\u043a\u0430\u044f \u043e\u0431\u0443\u0432\u044c',)
Default collation for table items is set to utf8_general_ci and my connection string is following.
mysql://root:Abc123#localhost/test?charset=utf8
Please help.
Thanks,
Your encoding is right:
>>> print(u'\u041c\u0443\u0436\u0441\u043a\u0430\u044f \u043e\u0431\u0443\u0432\u044c')
Мужская обувь
>>> print(repr(u'Мужская обувь'))
u'\u041c\u0443\u0436\u0441\u043a\u0430\u044f \u043e\u0431\u0443\u0432\u044c'
Your main problem that you are getting not a string but object that contains first result row. So you are getting repr of object.
Change .first() at the end of query to .scalar(). Scalar will return first column of first row.
As another variant you may access to row object and extract string from it.

How can I concatenate a string inside of a concatenated jsonb object in postgresql? In other words, I am using the JSONb concatenate operator as well as the text concatenate operator in the same query and running into trouble.
Or... if there is a totally different query I should be executing, I'd appreciate hearing suggestions. The goal is to update a row containing a jsonb column. We don't want to overwrite existing key value pairs in the jsonb column that are not provided in the query and we also want to update multiple rows at once.
My query:
update contacts as c set data = data || '{"geomatch": "MATCH","latitude":'||v.latitude||'}'
from (values (16247746,40.814140),
(16247747,20.900840),
(16247748,20.890570)) as v(contact_id,latitude) where c.contact_id = v.contact_id
The Error:
ERROR: invalid input syntax for type json
LINE 85: update contacts as c set data = data || '{"geomatch": "MATCH...
^
DETAIL: The input string ended unexpectedly.
CONTEXT: JSON data, line 1: {"geomatch": "MATCH","latitude":
SQL state: 22P02
Character: 4573
You might be looking for
SET data = data || ('{"geomatch": "MATCH","latitude":'||v.latitude||'}')::jsonb
-- ^^ jsonb ^^ text ^^ text
but that's not how one should build JSON objects - that v.latitude might not be a valid JSON literal, or even contain some injection like "", "otherKey": "oops". (Admittedly, in your example you control the values, and they're numbers so it might be fine, but it's still a bad practice). Instead, use jsonb_build_object:
SET data = data || jsonb_build_object('geomatch', 'MATCH', 'latitude', v.latitude)
There are two problems. The first is operator precedence preventing your concatenation of a jsonb object to what is read a text object. The second is that the concatenation of text pieces requires a cast to jsonb.
This should work:
update contacts as c
set data = data || ('{"geomatch": "MATCH","latitude":'||v.latitude||'}')::jsonb
from (values (16247746,40.814140),
(16247747,20.900840),
(16247748,20.890570)) as v(contact_id,latitude)
where c.contact_id = v.contact_id
;
I am trying to update a JSONB field in one table with data from another table. For example,
update ms
set data = data || '{"COMMERCIAL": 3.4, "PCT" : medi_percent}'
from mix
where mix.id = mss.data_id
and data_id = 6000
and set_id = 20
This is giving me the following error -
Invalid input syntax for type json
DETAIL: Token "medi_percent" is invalid.
When I change medi_percent to a number, I don't get this error.
{"COMMERCIAL": 3.4, "PCT" : medi_percent} is not a valid JSON text. Notice there is no string interpolation happening here. You might be looking for
json_build_object('COMMERCIAL', 3.4, 'PCT', medi_percent)
instead where medi_percent is now an expression (that will presumably refer to your mix column).
I've try to use where and like conditional on phone number or digital number actually this query will retrieved all the rows in my tables even those field is empty.
$cont = ClientCbcContact::where('contact_number_number', 'like', '%'.Request::input('phone').'%')->get();
However I use with string as below to retrieve my family_name which contain data heng sopheak, heng2 sopheak, heng, heng sopheak4 ** and **Request::input('name')= equal to heng sopheak. it select only one rows name heng sopheak.
ClientCbcGeneral::where('family_name', 'like', '%'. Request::input('name') .'%')->get();
MySQL LIKE queries require a string, not an integer, you could try casting the number to a string before performing the query.
Am trying to insert date from a table to another table using vba in access, But one of the date values from the table is blank. So while inserting the date to new table it shows Invalid use of null exception Run-time error 94.
If writing DAO code to clear a Date field, I found that I had to use "Empty". Null and "" won't work. So for field dtmDelivery (type Date), I had to use the following. strDelivery is just a string with the date in it.
Set rst = dbs.OpenRecordset("tblSomething", dbOpenDynaset)
If (strDelivery = "") Then
rst!dtmDelivery = Empty
Else
rst!dtmDelivery = strDelivery
End If
rst.Update
you can use the NZ() function to define a value that should be used instead of NULL. Internally a date is a float value where the number represents the days between 01.01.1900 and the date that should be stored. The part behind the decimal point represents hours/minutes (.25 for example is 6 AM). So you can use the NZ() funtion to replace NULL bei 0 (what would be interpreted as 01.01.1900).
Another solution would be to configure the target table in a way that it allows NULL values. You can do this easily in the design view of the table.
I think i figure it out , declare the variable to string. Then check whether value from the table is empty, then assign null to it.Other wise assign the value from the table.
for example
Dim newdate As String
Check whether the fetched values is null or not
If IsNull(rst![value]) Then
newdate = "null"
Else
newdate = rst![value]
End If
I encountered this problem and solved it this way.
SQL = "update mytable set mydatefield = '" & txtdate & "'"
On the txtdate on your form, put a date format to ensure date is either a real date or just blank.
I am trying to execute a native query and pass run-time parameters and get the result as a List. When I try to process the Object [], one of the columns fetched is a String. But it comes out as java.lang.Character instead of String. Here is the query below:
SELECT CASE
WHEN (TRUNC(abm.credit_card_expiration_date) BETWEEN trunc(SYSDATE) AND
trunc(last_day(SYSDATE))) THEN
'Expires'
ELSE
'Expired'
END EXP_STATUS,
TO_CHAR(abm.credit_card_expiration_date, 'MM/YY') EXP_DATE
FROM account_billing_methods abm
WHERE abm.account_id = 201103
AND abm.billing_type_id = 1
AND TRUNC(abm.credit_card_expiration_date) <= TRUNC(LAST_DAY(SYSDATE))
The EXP_STATUS column could not be typecasted into String as it is of type Character. Any ideas of why it does not work?

I had the same problem and changed the select clause of my query to:
EXP_STATUS || '' as EXP_STATUS
Then it is a VARCHAR instead of a CHAR and JPA will return it as a String instead of a Character.
If someone knows a better/more elegant solution, I would appreciate if you could share it.
