I have been working on this on for months. I just cannot get the natural (True alpha-numeric) results. I am shocked that I cannot get them as I have been able to in RPG since 1992 with EBCDIC.
I am looking for any solution in SQL, VBS or simple excel or access. Here is the data I have:
299-8,
3410L-87,
3410L-88,
420-A20,
420-A21,
420A-40,
4357-3,
AN3H10A,
K117GM-8,
K129-1,
K129-15,
K271B-200L,
K271B-38L,
K271D-200EL,
KD1051,
KD1062,
KD1092,
KD1108,
KD1108,
M8000-3,
MS24665-1,
SK271B-200L,
SAYA4008
The order I am looking for is the true alpha-numeric order as below:
AN3H10A,
KD1051,
KD1062,
KD1092,
KD1108,
KD1108,
K117GM-8,
K129-1,
K129-15,
MS24665-1,
M8000-3,
SAYA4008,
SK271B-200L
The inventory is 7800 records so I have had some problems with processing power as well.
Any help would be appreciated.

In native Excel, you can add multiple sorting columns to return the ASCII code for each character, but if the character is a number, then add a large number to the code (e.g 1000).
Then sort on each of the helper columns, including the first column in the table, but not in the sort.
The formula:
=IFERROR(CODE(MID($A1,COLUMNS($A:A),1))+AND(CODE(MID($A1,COLUMNS($A:A),1))>=48,CODE(MID($A1,COLUMNS($A:A),1))<=57)*1000,"")
The Sort dialog:
The results:
You can implement a similar algorithm using VBA, and probably SQL also. I dunno about VBS or Access.
You could try using format for left padding the string in order by
select column
from my_table
order by Format(column, "0000000000")
Add a sorting column:
, iif (left(fieldname, 1) between '0' and '9', 1, 0) sortField
etc
order by sortField, FieldName
Lets say you have your data in column "A". If you put this formula in column "B" =IFERROR(IF(LEFT(A1,1)+1>0,"ZZZZZZZ "&A1,A1),A1), it will automatically add Z in front of all numerical values, so that they will naturally appear after all alphabetical values when you sort A-Z. later you can find&replace that funny ZZZZZZ string...
There a number of approaches, but likely the least amount of work is to build two columns that split out the delimiter (-) in this case.
You then “pad” the results (spaces, or 0) right justified, and then sort on the two columns.
So in the query builder we have this:
SELECT Field1,
Format(
Mid(field1,1,IIf(InStr(field1,"-")=0,50,InStr(field1,"-")-1)),
">##########") AS Expr1,
Format(
Mid(field1,IIf(InStr(field1,"-")=0,99,InStr(field1,"-")+1)),
">##########") AS Expr2
FROM Data
When we run the above raw query we get this:
So now in the query builder, simply sort on the first derived column, and then sort on the 2nd derived column.
Eg this:
Run the query, and we get this result:
Edit:
Looking at you desired results, it looks like above sort is wrong. We have to RIGHT just and pad with 0’s.
So this 2nd try:
SELECT Field1,
Left(Mid(field1,1,IIf(InStr(field1,"-")=0,30,InStr(field1,"-")-1))
& String(30,"0"),30) AS Expr1,
Left(Mid(field1,IIf(InStr(field1,"-")=0,99,InStr(field1,"-")+1))
& String(30,"0"),30) AS Expr2
FROM Data
The results are thus this:
Given your small table size, then the above query should perform quite well.
The query I start out with has 40,000 lines of empty rows, which stems from a problem with the original spreadsheet from which it was taken.
Using CF16 server
I would like to do a Query of Queries on a variably named 'key column'.
In my query:
var keyColumn = "Permit No."
var newQuery = "select * from source where (cast('#keyColumn#' as varchar) <> '')";
Note: the casting comes from this suggestion
I still get all those empty fields in there.
But when I use "City" as the keyColumn, it works. How do the values in both those columns differ when they both say [empty string] on the query dump?
Is it a problem with column names? What kind of data are in those cells?
where ( cast('Permit No.' as varchar) <> '' )
The problem is the SQL, not the values. By enclosing the column name in quotes, you are actually comparing the literal string "P-e-r-m-i-t N-o-.", not the values inside that column. Since the string "Permit No." can never equal an empty string, the comparison always returns true. That is why the resulting query still includes all rows.
Unless it was fixed in ColdFusion 2016, QoQ's do not support column names containing invalid characters like spaces. One workaround is to use the "columnNames" attribute to specify valid column names when reading the spreadsheet. Failing that, another option is to take advantage of the fact that query columns are arrays and duplicate the data under a valid column name: queryAddColumn(yourQuery, "PermitNo", yourQuery["Permit No."]) (Though the latter option is less ideal because it may require copying the underlying data internally):
I'm trying to take a regular expression and split it by a pre-determined character, and then extract the final value of the returned list.
For example, my string may take the form:
name
WAYNE.ROONEY.226
ROSS.BARKLEY.HELLO.113
ADAM.A122
Pythonically, what I'm trying to do is:
for x in list:
my_val = x.split('.')[-1] #Return the last element of the list when split on .
e.g. desired output:
name value
WAYNE.ROONEY.226 226
ROSS.BARKLEY.HELLO.113 113
ADAM.A122 A122
Can anyone provide me any pointers in either Hive or Impala please?
If I can create this as a view, ideally, that would be perfect, but am also happy with generating actual output with it and then re-uploading to a table
Thank you!
For Hive:
select regexp_extract(NAME, '\\.([^\\.]+)$', 1) as VALUE
from WHATEVER
And pleeeease [edit] learn the power of regular expressions...
I am looking for a way to take data from one table and manipulate it and bring it to another table using an SQL query.
I have a Column called NumberStuff that has data like this in it:
INC000000315482
I need to cut off the INC portion of the number and convert it into an integer and store it into a Column in another table so that it ends up looking like this:
315482
Any help would be much appreciated!
Another approach is to use the Replace function. Either in TSQL or as a Derived Column Expression in SSIS.
TSQL
SELECT REPLACE(T.MyColumn, 'INC', '') AS ReplacedINC
SSIS
REPLACE([MyColumn], "INC", "")
This removes the character based data. It then becomes an optional exercise in converting to a numeric type before storing it to the target table or letting the implicit conversion happen.
Simplest version of what you need.
select cast(right(column,6) as int) from table
Are you doing this in a SSIS statement, or?...is it always the last 6 or?...
This is a little less dependant on your formatting...removes 0's and can be any length (will trim the first 3 chars and the leading 0's).
select cast(SUBSTRING('INC000000315482',4,LEN('INC000000315482') - 3) as int)
I found a weird problem with MySQL select statement having "IN" in where clause:
I am trying this query:
SELECT ads.*
FROM advertisement_urls ads
WHERE ad_pool_id = 5
AND status = 1
AND ads.id = 23
AND 3 NOT IN (hide_from_publishers)
ORDER BY rank desc
In above SQL hide_from_publishers is a column of advertisement_urls table, with values as comma separated integers, e.g. 4,2 or 2,7,3 etc.
As a result, if hide_from_publishers contains same above two values, it should return only record for "4,2" but it returns both records
Now, if I change the value of hide_for_columns for second set to 3,2,7 and run the query again, it will return single record which is correct output.
Instead of hide_from_publishers if I use direct values there, i.e. (2,7,3) it does recognize and returns single record.
Any thoughts about this strange problem or am I doing something wrong?
There is a difference between the tuple (1, 2, 3) and the string "1, 2, 3". The former is three values, the latter is a single string value that just happens to look like three values to human eyes. As far as the DBMS is concerned, it's still a single value.
If you want more than one value associated with a record, you shouldn't be storing it as a comma-separated value within a single field, you should store it in another table and join it. That way the data remains structured and you can use it as part of a query.
You need to treat the comma-delimited hide_from_publishers column as a string. You can use the LOCATE function to determine if your value exists in the string.
Note that I've added leading and trailing commas to both strings so that a search for "3" doesn't accidentally match "13".
select ads.*
from advertisement_urls ads
where ad_pool_id = 5
and status = 1
and ads.id = 23
and locate(',3,', ','+hide_from_publishers+',') = 0
order by rank desc
You need to split the string of values into separate values. See this SO question...
