I have four fields to get concatenated with comma separator but if any of the field is blank, additional comma will not be added.
For example - Var1 + Var2 + Var3 + Var4
If Var1 is blank then output should be
Var2, Var3,Var4
I am using Java 6
I tried to follow the link but getting version issue. Please share solution which is compatible with lower version of java
Join comma if not empty or null

Input String : ["http://info.wealthenhancement.com/ppc-rt-retirement-planning"]
Output String : info.wealthenhancement.com/ppc-rt-retirement-planning
Please help to get output string.
Thanks
Use the substr function to only take characters from the 8th character to the end:
select
'http://info.wealthenhancement.com/ppc-rt-retirement-planning' as orig_value,
substr(orig_value, 8) as new_value
The output is:
+-------------------------------------------------------------+-------------------------------------------------------+
|ORIG_VALUE | NEW_VALUE |
+-------------------------------------------------------------+-------------------------------------------------------+
|http://info.wealthenhancement.com/ppc-rt-retirement-planning | info.wealthenhancement.com/ppc-rt-retirement-planning |
+-------------------------------------------------------------+-------------------------------------------------------+
This will work for http and https URLs by splitting using // as a delimiter. Only the last statement is required. The other two show how it's done built into steps:
-- Set a session variable to the string
set INPUT_STRING = '["http://info.wealthenhancement.com/ppc-rt-retirement-planning"]';
-- Trim leading and trailing square brackets and double quotes
select (trim($INPUT_STRING, '"[]'));
-- Split using // as a delimiter and keep only the right part and cast as string
select split((trim($INPUT_STRING, '"[]')), '//')[1]::string as URL
I have a very long string that must be broken into multiple lines. How can I do that in zeppelin?
The error is error: missing argument list for method + in class String:
Here is the more complete error message:
<console>:14: error: missing argument list for method + in class String
Unapplied methods are only converted to functions when a function type is expected.
You can make this conversion explicit by writing `$plus _` or `$plus(_)` instead of `$plus`.
val q = "select count(distinct productId),count(distinct date),count(distinct instock_inStockPercent), count(distinct instock_totalOnHand)," +
In Scala (using Apache Zeppelin as well as otherwise), you can write expressions covering multiple lines by wrapping them in parentheses:
val text = ("line 1"
+ "line 2")
Using parentheses
As Theus mentioned. One way is parentheses.
val text = ("line 1" +
"line 2")
Actually all multiline statements which break by semantics can be included by parentheses. like.
(object.function1()
.function2())
Using """
For multiline string. We can use """, like this,
val s = """line 1
line2
line3"""
The leading space before line2 and line3 will be included. If we don't want to to have the leading spaces. We can use like this.
val s = """line 1
|line2
|line3""".stripMargin
Or using different strip character
val s = """line 1
$line2
$line3""".stripMargin('$')
I am comparing two string.I am reading String 1 i.e expectedResult from excelsheet and String 2 i.e actualResult i am getting from web page by using " getElementByXPath("errorMsg_userPass").getText();
but when i equate two string even though they are same result of comparison are coming false i.e they are not same.
enter image description here
I don't know why it is happening like this .Please Help
use trim() to remove leading and trailing spaces!!
I recommend you looking at the exact bytes of the actual and expected strings. There might be for instance an unbreakable space instead of a regular space and then they will look the same but won't be the same for equals.
You can see the difference by running the following snippet:
String a = new String("a\u00A0b");
String b = new String ("a b");
System.out.println(a + "|" + Arrays.toString(a.getBytes()));
System.out.println(b + "|" + Arrays.toString(b.getBytes()));
Which will output:
a b|[97, -62, -96, 98]
a b|[97, 32, 98]
I have a database that has multiple columns populated with various numeric fields. While trying to populate from a CSV, I must have mucked up assigning delimited fields. The end result is a column containing It's Correct information, but also contains the next column over's data- seperated by a comma.
So instead of Column UPC1 containing "958634", it contains "958634,95877456". The "95877456" is supposed to be in the UPC2 column, instead UPC2 is NULL.
Is there a way for me to split on the comma and send the data to UPC2 while keeping UPC1 data before the comma in tact?
Thanks.
You can do this with string functions. To query the values and verify the logic, try this:
SELECT
LEFT(UPC1, CHARINDEX(',', UPC1) - 1),
SUBSTRING(UPC1, CHARINDEX(',', UPC1) + 1, 1000)
FROM myTable;
If the result is what you want, turn it into an update:
UPDATE myTable SET
UPC1 = LEFT(UPC1, CHARINDEX(',', UPC1) - 1),
UPC2 = SUBSTRING(UPC1, CHARINDEX(',', UPC1) + 1, 1000);
The expression for UPC1 takes the left side of UPC1 up to one character before the comma.
The expression for UPC2 takes the remainder of the UPC1 string starting one character after the comma.
The third argument to SUBSTRING needs some explaining. It's the number of characters you want to include after the starting position of the string (which in this case is one character after the comma's location). If you specify a value that's longer than the string SUBSTRING will just return to the end of the string. Using 1000 here is a lot easier than calculating the exact number of characters you need to get to the end.
I have a string "I love McDonald's burgers. it's the best."
and I would like to insert it into a column breaking them into 15 character strings.
Hence I need the result as string inserted in 3 rows
I love McDonald
's burgers. it'
s the best.
But if I use ' ' to include the ', an extra ' is present in the string which will affect my calculation of 15 character breakage.
Is there any other way to include ' without having to use one more ' to escape it?
Please help.
You don't need to add an extra ' if you're breaking the string into a variable:
DECLARE
mcdonald_string VARCHAR2(50) := 'I love McDonald''s burgers. it''s the best.';
BEGIN
WHILE LENGTH(mcdonald_string) > 0 LOOP
INSERT INTO your_table(your_field) VALUES (SUBSTR(mcdonald_string,1,15));
mcdonald_string := SUBSTR(mcdonald_string,16);
END LOOP;
COMMIT;
END;
Doubling the quotation marks within a complicated literal,
particularly one that represents a SQL statement, can be tricky. You
can also use the following notation to define your own delimiter
characters for the literal. You choose a character that is not present
in the string, and then do not need to escape other single quotation
marks inside the literal:
-- q'!...!' notation allows the of use single quotes
-- inside the literal
string_var := q'!I'm a string, you're a string.!';
