I am using regex in drool for validating the password.
rule "Reset Password"
when
$event : IIPEvent ( name == 'save')
$vm : Login(userProfile != null)
then
if($vm.getPassword().getValue() != null && $vm.getPassword().getValue().matches('^(?=.*[A-Za-z])(?=.*\d)[A-Za-z\d]{8,}$'))
outcome.addFieldError('password', 'Password minimum eight characters, at least one letter and one number', $vm, false);
end
When I deploy this in Tomcat server, I am getting following exception
line 11:104 no viable alternative at character 'd'
line 11:113 no viable alternative at character '\'

If any one know that how to resolve it, please let me know
You should be doing your matching on the left hand side, not the right hand side. That's what the 'matches' operator is for.
rule "Reset Password"
when
exists(IIPEvent(name == "save"))
$vm : Login( userProfile != null,
password != null,
password matches "(?=.*[A-Za-z])(?=.*\\d)[A-Za-z\\d]{8,}$")
then
outcome.addFieldError("password", "Password minimum eight characters, at least one letter and one number", $vm, false);
end
As to why you were getting the error -- you have \d instead of \\d. You need to escape the backslash for character classes within strings. You can tell this is the issue from the error messages: no viable alternative at character 'd' and then no viable alternative at character '\'.

I want to create a goto expression as follows
//label
<bb 2> :
//goto
goto <bb 2>;
The following grammar works fine for a simple ID. I have no idea how to reference the <ID INT>
in the goto expression.
Goto returns Goto:
{Goto}
'goto' goto+=[Label] ';'
;
LabelDef returns LabelDef:
{LabelDef}
label+= Label ':'
;
Label returns Label:
{Label}
name= ID
;
Do have any idea how to that?
the feature you are looking for is a DataType rule
Goto returns Goto:
{Goto}
'goto' goto+=[Label|IDandINT] ';'
;
LabelDef returns LabelDef:
{LabelDef}
label+= Label ':'
;
Label returns Label:
{Label}
name= IDandINT
;
IDandINT: ID INT;
you may also introduce / customize DefaultTerminalConverters/IValueConverter for the datatype rule to normalize whitespace
I think you want a terminal that is essentially "ID INT" and then use it to crossreference your Label.
I think this is going to be a lot of work just to be able to allow "spaces" in your labels. Why not simply rely on terminal "ID" and users may name them "bb2" if they wish?
Error getting while insert bulk rows with Pentaho Data Interrogator. I am using PostgreSQL
ERROR: invalid byte sequence for encoding "UTF8": 0x00
"UTF8": 0x00 = "null character". You can use "Modified Javascript" step, and then apply a mask pattern as follows:
function removeNull(e) {
if(e != null)
return e.replace(/\0/g, '');
else
return '';
}
var replacedString = removeNull(fieldToRemoveNullChars);
Select the new field for the Modified Javascript output, and voilla!. Use to have this problem with AS400 incoming data.
PostgreSQL is very strict content of text fields, and doesn't allow 0x00 in utf8 encoded fields. You should to fix your input data.
Some possible solution https://superuser.com/questions/287997/how-to-use-sed-to-remove-null-bytes
Finally I got the solution:
In Table Input, check the "Enable lazy conversion" option
Enter the "Select Values" step Select all fields and on the forced "Metadata" tab by entering the "UTF-8" encoding for all fields.
i am trying to get values from database by using following query
SELECT Distinct org.name AS org, sto.ad_org_id AS wh_nearstoredetails_id, sum(sto.qtyonhand) AS qty, pro.name AS product
FROM ad_org org, m_storage_detail sto, m_product pro
WHERE sto.ad_org_id::text = org.ad_org_id::text
AND (sto.m_locator_id::text IN ( select cast(m_locator.m_locator_id as text)
from m_locator,m_warehouse
where m_warehouse.isactive = cast('Y' as varchar)
and m_warehouse.em_ai_warehouseparent::text not like cast('' as text)
and m_warehouse.m_warehouse_id::text = m_locator.m_warehouse_id::text
and m_locator.isdefault = cast('Y' as varchar)))
AND sto.m_product_id::text = pro.m_product_id::text
AND sto.qtyonhand >= cast(1 as numeric)
AND sto.ad_org_id::text IN ( SELECT cast(m_warehouse.ad_org_id as text)
FROM m_warehouse
WHERE m_warehouse.em_ai_warehouseparent::text not like cast('' as text))
GROUP BY org.name,sto.ad_org_id,pro.name
ORDER BY org.name, pro.name;
after creating this i also created a class to call this query and get data but when i deploy my project i am getting following error
WARN - SQL Command failed with: ERROR: operator does not exist: character varying !
Hint: No operator matches the given name and argument type(s). You might need to add explicit type casts.
please help to solve this issue.
i finally found the mistake what i made.
the problem in the above query is i'm trying to make type cast of null value
now i changed the condition to check 'is not null' than "not like ''"
and even i don't need to add cast operation it's useless.
anyways thanks for you response. :)
I'm doing a little application for the work and it includes a form. When the person using the form doesn't put a value in a data type "numeric" (lets say a PIN number) or even a date in one of my "date" Data Type fields (lets say his anniverssary), it returns me with the errors as follow:
Error Type – Type d'erreur
_Microsoft OLE DB Provider for ODBC Drivers (0x80004005)_
ERROR: invalid input syntax for type numeric: ""; Error while executing the query
Error Type – Type d'erreur
_Microsoft OLE DB Provider for ODBC Drivers (0x80004005)_
ERROR: syntax error at or near ")"; Error while executing the query
So it seems that when the person using the form enters nothing, it returns the string "empty" that is "".
Why can't the numeric type and data type read that as a NULL entry? These fields are not mandatory and so I need to have them be sometimes blank.
How can I make it possible? Is their a way to keep using "numeric" and "date" type so that when the user enters nothing in those fields, the table fills with a blank case insted of giving me this error?
Here is my sql statement :
trsConn.EXECUTE "INSERT INTO ""TRS"".employeetbl ( "& _
"""firstName"", " & _
"""lastName"" , " & _
"""detContract"", " & _
"sle, " & _
"""posNumber"" "& _
") VALUES (" & _
"'" & Request.Form("empFirst") & "', " & _**
"'" & Replace(Request.Form("empLast"), "'", "`") & "', " & _
"'" & Request.Form("dateContract") & "', " & _
"'" & Request.Form("sle") & "', " & _
"'" & Request.Form("posNum") & "');"
(The posNum and dateContract are both respectivly of type "numeric" and "date"
Thanks so much for the help. Looking forward for hearing what you geniuses have to say.
The concept of NULL in SQL is pretty muddled and inconsistent ... but it's very clear that '' is distinct from NULL.
'' isn't NULL, it's '', the empty string. You can't convert it to a date, number, etc:
regress=# SELECT CAST('' AS DATE);
ERROR: invalid input syntax for type date: ""
LINE 1: SELECT CAST('' AS DATE);
^
regress=# SELECT CAST('' AS NUMERIC);
ERROR: invalid input syntax for type numeric: ""
LINE 1: SELECT CAST('' AS NUMERIC);
^
Some products - notably Microsoft Access and old versions of MySQL - are confused about that matter. NULL is NULL, '' is the empty string; they aren't the same thing. You can't convert one to the other.
So it seems that when the person using the form enters nothing, it
returns the string "empty" that is "". Why can't the numeric type and
data type read that as a NULL entry? These fields are not mandatory
and so I need to have them be sometimes blank.
That's your application's job. When your app it sees the empty string come in on a form field for a numeric, date, or similar, it should send NULL to the database, not ''. That's normally a routine part of converting data from user input before it's supplied to the database. It is vital that you do such conversion; you should never just send values from the user straight to the database.
A quick search suggests that asp classic uses null or undefined as its null values; you should be able to pass them into your prepared statements when something is null.
The fact that you get a syntax error after the error about '' suggests that you're building your SQL statements as strings, not using prepared statements with placeholders. (Thanks JayC for the SO question ref). This is begging for SQL injection; in other words your application is critically insecure. Imagine what happens if the user enters the "date":
2012-01-01'); DROP SCHEMA public;--
and your app happily turns that into
INSERT INTO sometable (blah, blah, blah) VALUES (1, 2, DATE '2012-01-01'); DROP SCHEMA public;--');
The DROP SCHEMA then merrily executes and whoops, splat, there goes your database. That's just the dumbest, simplest kind of SQL injection attack too.
I have a field named rspec in a table trace.
So for now the field is like "Vol3/data/20070204_191426_FXBS.v3a".
All I need is a query to change it to the format "Vol3/data/20070204_191426_FXBS.V3A".
Assuming the current version:
select left(rspec, - 3)||upper(right(rspec, 3))
from trace
For older versions:
select substr(rspec, 1, length(rspec) - 3)||upper(substring(rspec from '...$'))
from trace
Or, to cover all possibilities like
file extensions of variable length: abc123.jpeg
no file extension at all: abc123
dot as last character: abc123.
multiple dots: abc.123.jpg
SELECT CASE WHEN rspec ~~ '%.%'
THEN substring(rspec, E'^.*\\.')
|| upper(substring(rspec , E'([^.]*)$'))
ELSE rspec
END AS rspec
FROM (VALUES
('abc123.jpeg')
, ('abc123')
, ('abc123.')
, ('abc.123.jpg')
) ASx(rspec); -- testcases
Explain:
If the string has no dot, use the string.
Else, take everything up to and including the last dot in the string.
Append everything after the last dot in upper case.
