Query to find zip codes with ending '0000' - sql-server

I need to find all zip codes in the database that end with '0000'. Using the below query, I was able to return all zip codes that are 9 digits in length. But how do I add return back only those zipcodes that have are 9 digits in length AND have 0000? I'm sure it's simple but I'm still really new to querying. :)
example: 922340000
Select Addresszipcode
from dbo.CR_MEMBER_AllMemberDetails
where len(Addresszipcode) = 9

Select Addresszipcode
from dbo.CR_MEMBER_AllMemberDetails
where len(Addresszipcode) = 9
and Addresszipcode like '%0000'

SELECT Addresszipcode
FROM dbo.CR_MEMBER_AllMemberDetails
WHERE LEN(AddressZipCode)= 9 AND RIGHT(AddressZipCode, 4) = '0000'

You need to use a combination of the LEN() function and the LIKE operator.
SELECT Addresszipcode FROM dbo.CR_MEMBER_AllMemberDetails
WHERE LEN(AddressZipCode)=9 AND AddressZipCode LIKE '%0000'
The LEN(AddressZipCode) part of the WHERE clause will only return rows with a length of 9. The AddressZipCode LIKE '%0000' will only return rows that end with 0000. When using the LIKE operator, the percent sign % acts as a wildcard. In essence, you're saying "WHERE AddressZipCode starts with anything and ends with 0000".
EDIT
In response to your comment, here is the SQL to trim the 0's:
SELECT CASE WHEN LEN(AddressZipCode)=9 AND AddressZipCode LIKE '%0000'
THEN LEFT(AddressZipCode,5) ELSE AddressZipCode END AS AddressZipCode

How to check if a numeric column value is in ascending or descending order. eg. 12345 or 654321

I need help with a SQL query to check if a numeric column contains a number in ascending or descending order.
eg. 123456 or 654321
This is to avoid people entering some random values in a customer phone number column, users are required to give valid phone number input.
I want to achieve this without using a function.
UPDATE: #LukStorms had kindly answered my question. Many thanks. Thanks to others who looked at my question and left comments. However I would really appreciate if the comment helps solve the problem. My scenario is different, I cannot post the entire use case here. The ask is I must validate the column in the same way.
To check if it's like a sequence of digits?
Then you can simply use LIKE
select num
, cast(case
when '1234567890123456789' like concat('%',num,'%')
then 1
when '9876543210987654321' like concat('%',num,'%')
then 1
else 0 end as bit) as isSequence
from (values
(123456),
(765432),
(797204)
) nums(num)
num
isSequence
123456
True
765432
True
797204
False
Or use CHARINDEX
select num
, cast(case
when 0 < charindex(concat(num,''),'1234567890123456789') then 1
when 0 < charindex(concat(num,''),'9876543210987654321') then 1
else 0 end as bit) as isSequence
from (values
(123456),
(765432),
(797204)
) nums(num)

SQL Server - How to get last numeric value in the given string

I am trying to get last numeric part in the given string.
For Example, below are the given strings and the result should be last numeric part only
SB124197 --> 124197
287276ACBX92 --> 92
R009321743-16 --> 16
How to achieve this functionality. Please help.
Try this:
select right(#str, patindex('%[^0-9]%',reverse(#str)) - 1)
Explanation:
Using PATINDEX with '%[^0-9]%' as a search pattern you get the starting position of the first occurrence of a character that is not a number.
Using REVERSE you get the position of the first non numeric character starting from the back of the string.
Edit:
To handle the case of strings not containing non numeric characters you can use:
select case
when patindex(#str, '%[^0-9]%') = 0 then #str
else right(#str, patindex('%[^0-9]%',reverse(#str)) - 1)
end
If your data always contains at least one non-numeric character then you can use the first query, otherwise use the second one.
Actual query:
So, if your table is something like this:
mycol
--------------
SB124197
287276ACBX92
R009321743-16
123456
then you can use the following query (works in SQL Server 2012+):
select iif(x.i = 0, mycol, right(mycol, x.i - 1))
from mytable
cross apply (select patindex('%[^0-9]%', reverse(mycol) )) as x(i)
Output:
mynum
------
124197
92
16
123456
Demo here
Here is one way using Patindex
SELECT RIGHT(strg, COALESCE(NULLIF(Patindex('%[^0-9]%', Reverse(strg)), 0) - 1, Len(strg)))
FROM (VALUES ('SB124197'),
('287276ACBX92'),
('R009321743-16')) tc (strg)
After reversing the string, we are finding the position of first non numeric character and extracting the data from that position till the end..
Result :
-----
124197
92
16

Check last bit in a hex in SQL

I have a SQL entry that is of type hex (varbinary) and I want to do a SELECT COUNT for all the entries that have this hex value ending in 1.
I was thinking about using CONVERT to make my hex into a char and then use WHERE my_string LIKE "%1". The thing is that varchar is capped at 8000 chars, and my hex is longer than that.
What options do I have?
Varbinary actually works with some string manipulation functions, most notably substring. So you can use eg.:
select substring(yourBinary, 1, 1);
To get the first byte of your binary column. To get the last bit then, you can use this:
select substring(yourBinary, len(yourBinary), 1) & 1;
This will give you zero if the bit is off, or one if it is on.
However, if you really only have to check at most the last 4-8 bytes, you can easily use the bitwise operators on the column directly:
select yourBinary & 1;
As a final note, this is going to be rather slow. So if you plan on doing this often, on large amounts of data, it might be better to simply create another bit column just for that, which you can index. If you're talking about at most a thousand rows or so, or if you don't care about speed, fire away :)
Check last four bits = 0001
SELECT SUM(CASE WHEN MyColumn % 16 IN (-15,1) THEN 1 END) FROM MyTable
Check last bit = 1
SELECT SUM(CASE WHEN MyColumn % 2 IN (-1,1) THEN 1 END) FROM MyTable
If you are wondering why you have to check for negative moduli, try SELECT 0x80000001 % 16
Try using this where
WHERE LEFT(my_string,1) = 1
It it's text values ending in 1 then you want the Right as opposed to the Left
WHERE RIGHT(my_string,1) = 1

Natural sort for SQL Server?

I have a column that is typically only numbers (sometimes it's letters, but that's not important).
How can I make it natural sort?
Currently sorts like this: {1,10,11,12,2,3,4,5,6,7,8,9}
I want it to sort like this: {1,2,3,4,5,6,7,8,9,10,11,12}
IsNumeric is "broken", ISNUMERIC(CHAR(13)) returns 1 and CAST will fail.
Use ISNUMERIC(textval + 'e0'). Final code:
ORDER BY
PropertyName,
CASE ISNUMERIC(MixedField + 'e0') WHEN 1 THEN 0 ELSE 1 END, -- letters after numbers
CASE ISNUMERIC(MixedField + 'e0') WHEN 1 THEN CAST(MixedField AS INT) ELSE 0 END,
MixedField
You can mix order parameters...
Cast it. Also, don't forget to use IsNumeric to make sure you only get the numbers back (if they include letters it IS important ;).
SELECT textval FROM tablename
WHERE IsNumeric(textval) = 1
ORDER BY CAST(textval as int)
Also, cast to the datatype that will hold the largest value.
If you need the non-numbers in the result set too then just append a UNION query where IsNumeric = 0 (order by whatever you want) either before or after.
Have you tied using:
'OrderBy ColumnName Asc'
at the end of your query.

valid record in SQL query

I have a table with few columns and one of the column is DockNumber. I have to display the docknumbers if they confirm to a particular format
First five characters are numbers followed by a - and followed by 5 characters. The last but one character should be a alpha.
12345-678V9
How can I check in SQL if the first 5 characters are numbers and there is a hyphen and next 3 are numbers and last but one is an alpha.
Building on #gbn's answer, this checks to make sure the length is 11 (in case the #val is not a char(11) or varchar(11) and also checks to make sure the second to last char is alpha
DECLARE #val VARCHAR(20)
SET #val = '12345-678V9'
SELECT CASE WHEN LEN(#val) = 11 AND #val LIKE '[0-9][0-9][0-9][0-9][0-9]-[0-9][0-9][0-9][A-Z0-9][0-9]'
THEN 'isMatch'
ELSE 'isNotMatch'
END AS [Valid]
you can use this, you will have to figure it out on how to use this...
SELECT Case when
Cast(ISNUMERIC(LEFT(#Str,5)) as int) + case when substring(#str,6,1)= '-' then 1 else 0 end +case when substring(#str,10,1) like '[a-z]' then 1 else 0 end =3
THEN 'Matched'
Else 'NotMatched'
End
Regular Expressions can be your friend.
LIKE '[0-9][0-9][0-9][0-9][0-9]-[0-9][0-9][0-9][A-Z][0-9]'
Now, this allows lower case a-z too. You'd need to coerce collation if you wanted upper case only
Value COLLATE Latin_General_BIN
LIKE '[0-9][0-9][0-9][0-9][0-9]-[0-9][0-9][0-9][A-Z][0-9]' COLLATE Latin_General_BIN
PATINDEX is probably the ideal solution.
Select ...
From Table
Where PatIndex('[0-9][0-9][0-9][0-9][0-9]-[0-9][0-9][0-9][A-Z][0-9]', DockNumber) > 0
Where DockNumber Like '[0-9][0-9][0-9][0-9][0-9][-][0-9][0-9][0-9][a-z][0-9]
should work, but i would suggest using Regular expression in code. Much easier if it is possible.
The regex should be '^\d{5}-\d{3}[A-Z]\d$', because without ^ and $ it would find longer strings that contain that sequence (122 12345-678V9 34).
Use rule
CREATE RULE pattern_rule
AS
#value LIKE '[0-9][0-9][0-9][0-9]-[0-9][0-9][0-9][0-9][A-Z][0-9]'
Then bind rule to column
