I am trying to use the Internationalization feature of the Play Framework.
It involves the creation of a new conf file for each language that we want to support. Example for french we create a messages.fr file in the conf folder.
Inside it we define key-values like this:
Hello.World = 'Bonjour le monde'
Now the issue is that I have lines that contain characters like "," and "(" and if these are included in the key then we get the error in parsing from the MessageApi
Example
Hello.(World) = 'Bonjour (le monde)'
Here the "(" before and after World is throwing an error while parsing.
Anyone having any idea how we could achieve this?
Try to escape these special characters:
Hello.\(World\) = 'Bonjour (le monde)'
Other examples:
string_one = String for translation 1
string_two = one + one \= two
# String key with spaces
key\ with\ spaces = This is the value that could be looked up with the key "key with spaces".
# Backslash in value should be escaped by another backslash
path=c:\\wiki\\ templates
Also, you can try to escape special characters by using Java Unicode:
Hello.\u0028World\u0029 = 'Bonjour (le monde)'

“VENKATA,KRISHNA”
I want output like below
VENKATA,KRISHNA
Can anyone help me with this
Check out the Ereplace function - it allows to replace certain characters so you could rplace " with '' (empty string).
An alternative is TRIM - you can specify which character the command should trim and also if All occurrences or Both (from both sides of the string) plus more.
When I tried to copy the text from before the first comma in the first column to the second column using the following command:
UPDATE Table_Name
SET second_column = SUBSTRING_INDEX(first_column, ‘,’, 1);
I got the error message:
Error Code: 1582. Incorrect parameter count in the call to native function 'SUBSTRING_INDEX'
What is going wrong?
Thanks in advance.
The error came from copying and pasting the command from a non-programming text editor (i.e. Word):
The quotes around the delimiter were changed from two normal single quotes (') and (') to left and right single quotes (‘) and (’).
Changing the delimiter to two normal single quotes around the delimiter solved the problem:
UPDATE Table_Name
SET second_column = SUBSTRING_INDEX(first_column, ',', 1);
I bet it's totaly simple and i just don't see it, but i don't get it ..
I execute the following command in DB2 command line processor:
DB2 LOAD FROM "DB_ACC_PASS_REGEXP.del" OF DEL METHOD P (1, 2, 3, 4, 5) MESSAGES "DB_ACC_PASS_REGEXP.del.msg" INSERT INTO DB_ACC_PASS_REGEXP (APP_ID,APREGEXP,EXPLAIN_TEXT,ID,OPT_KZ) NONRECOVERABLE INDEXING MODE REBUILD
Which loads the Data specified in following File into the database.
1,"[a-z]",,1,0
1,"[A-Z]",,2,0
1,"[0-9]",,3,0
1,"[!|\"|§|$|%|&|/|(|)|=|?|`|´|*|+|~|'|#|-|_|.|:|,|;|µ|<|>| |°|^]",,4,0
^
Here is the Problem
The Problem is, that only 3 of these 4 inserts will be accepted. The last one will be rejected, because DB2 Load doesn't notice the escape character before the double quotation mark.
if I change the last line to:
1,"[!|x|§|$|%|&|/|(|)|=|?|`|´|*|+|~|'|#|-|_|.|:|,|;|µ|<|>| |°|^]",,4,0
^
Here is the changed character
there is no problem ..
WHY doesn't the escape character "\" work??
edit
Okay.. I just tryed it the oracle way now and that works ... I escape " with another " so my Line looks like
1,"[!|""|§|$|%|&|/|(|)|=|?|`|´|*|+|~|'|#|-|_|.|:|,|;|µ|<|>| |°|^]",,4,0
But that's only a way to do it .. That doesn't explain why IBM offers the Backslash as an escape character (http://pic.dhe.ibm.com/infocenter/db2luw/v9r7/index.jsp?topic=%2Fcom.ibm.db2.luw.admin.cmd.doc%2Fdoc%2Fr0008305.html)
Using LOAD with ascii / delimited files requires to tune the file type modifiers (look on Table 6 and Table 8 of the docu page you linked). I am not quite sure, but I can't remember using backslash as escape character in DB2.
You can either use another character delimiter as double quotes with chardel option or force no character delimiter with nochardel option.
BUT ...
In your case you need special characters as regular expressions, so you will always need to escape " with "" and ' with ''. I think there is no other way to get this working.
I need to update a record, which contains literal percent signs, using PostgreSQL in Railo. The query looks like
<cfquery>
update foo set bar = 'string with % in it %'
</cfQuery>
It throws error as ColdFusion normally interprets it as a wildcard character. I can escape it using the following query.
<cfquery>
update foo set bar = 'string with escaped \% in it \%'
</cfQuery>
However, the record now contains "\%" in the database and will be displayed on the page as "\%".
I found a documentation with an example of escaping percent sign in a SELECT. But it does not work for me: syntax error at or near "ESCAPE".
SELECT emp_discount
FROM Benefits
WHERE emp_discount LIKE '10\%'
ESCAPE '\';
Is there a better to achieve the same goal? The underlining database is PostgreSQL. Thanks!
Queryparameters escape special characters. Yet another reason to use them.
