I am trying to write a SQL query that only returns rows where a specific column (let's say 'amount' column) contains numbers comprising of only one digit, e.g. only '1's (1111111...) or only '2's (2222222...), etc.
In addition, 'amount' column contains numbers with decimal points as well and these kind of values should also be returned, e.g. 1111.11, 2222.22, etc
If you want to make the query generic that you don't have to specify each possible digit you could change the where to the following:
WHERE LEN(REPLACE(REPLACE(amount,LEFT(amount,1),''),'.','') = 0
This will always use the first digit as comparison for the rest of the string
If you are using SQL Server, then you can try this script:
SELECT *
FROM (
SELECT CAST(amount AS VARCHAR(30)) AS amount
FROM TableName
)t
WHERE LEN(REPLACE(REPLACE(amount,'1',''),'.','') = 0 OR
LEN(REPLACE(REPLACE(amount,'2',''),'.','') = 0
I tried like this in place of 1111111 replace with column name:
Select replace(Str(1111111, 12, 2),0,left(11111,1))

Here is my problem statement:
I have single column table having the data like as :
ROW-1>> 7302-2210177000-XXXX-XXXXXX-XXX-XXXXXXXXXX-XXXXXX-XXXXXX-U-XXXXXXXXX-XXXXXX
ROW-2>> 0311-1130101-XXXX-000000-XXX-XXXXXXXXXX-XXXXXX-XXXXXX-X-XXXXXXXXX-WIPXXX
Here i want to separate these values from '-' and load into a new table. There are 11 segments in this string separated by '-', therefore, 11 columns. The problem is:
A. The length of these values are changing, however, i have to keep it as the length of these values in the standard format or the length which it has
e.g 7302- (should have four values, if the value less then that then keep that value eg. 73 then it should populate 73.
Therefore, i have to separate as well as mentation the integrity. The code which i am writing is :
select
SUBSTR(PROFILE_ID,1,(case when length(instr(PROFILE_ID,'-')<>4) THEN (instr(PROFILE_ID,'-') else SUBSTR(PROFILE_ID,1,4) end)
)AS [RQUIRED_COLUMN_NAME]
from [TABLE_NAME];
getting right parenthesis error
Please help.
I used the regex_substr SQL function to solve the above issue. Here below is an example:
select regex_substr('7302-2210177000-XXXX-XXXXXX-XXX-XXXXXXXXXX-XXXXXX-XXXXXX-U-XXXXXXXXX-XXXXXX ROW-2>> 0311-1130101-XXXX-000000-XXX-XXXXXXXXXX-XXXXXX-XXXXXX-X-XXXXXXXXX-WIPXXX',[^-]+,1,1);
Output is: 7302 --which is the 1st segment of the string
Similarly, the send string segment which is separated by "-" in the string can be obtained by just replacing the 1 with 2 in the above query at the end.
Example : select regex_substr('7302-2210177000-XXXX-XXXXXX-XXX-XXXXXXXXXX-XXXXXX-XXXXXX-U-XXXXXXXXX-XXXXXX ROW-2>> 0311-1130101-XXXX-000000-XXX-XXXXXXXXXX-XXXXXX-XXXXXX-X-XXXXXXXXX-WIPXXX',[^-]+,1,2);
output: 2210177000 which is the 2nd segment of the string
Say I have a table named 'Parts'. I am looking to create a SQL query that compares the first X characters of two of the fields, let's call them 'PartNum1' and 'PartNum2'. For example, I would like to return all records from 'Parts' where the first 6 characters of 'PartNum1' equals the first 6 characters of 'PartNum2'.
Parts
PartNum1
PartNum2
12345678
12345600
12388888
12345000
12000000
14500000
the query would only return row 1 since the first 6 characters match. MS SQL Server 2017 in case that makes a difference.
If they are strings, use left():
left(partnum1, 6) = left(partnum2, 6)
This would be appropriate in a where, on, or case expression. Note that using left() would generally prevent the use of indexes. If this is for a join and you care about performance, you might want to include a computed column with the first six characters.
you can try something like this. I am assuming datatype as integer. You can set size of varchar based on length of fields.
select *
from Parts
WHERE SUBSTRING(CAST(PartNum1 AS VARCHAR(max)), 1,6) = SUBSTRING(CAST(PartNum2 AS VARCHAR(max)), 1,6)
You can go for simple division to see if the numerator matches for those partnumbers.
DECLARE #table table(partnum int, partnum2 int)
insert into #table values
(12345678, 12345600)
,(12388888, 12345000)
,(12000000, 14500000);
select * from #table where partnum/100 = partnum2/100
partnum
partnum2
12345678
12345600
i have a dataset in SQL server which has a column i wish to parse out.
Looking to get positive and negative values onto different columns and also if there is a multiplier to put in different column against the value it is to be multiplied against.
EG of how the column looks that i want to parse out
create table #temped (
originalstring varchar(100)
)
insert into #temped
select 'SUM([S720]) - SUM([S719]) * 2 + SUM([S719])'
insert into #temped
select 'SUM([R382]) + SUM([R989])'
insert into #temped
select 'SUM([S716]) * .295'
I would like to put the positive values in one column, the negative in another and the multiplier in another. the multiplier should be on the same row as the one it is to be multiplied against.
Example output of the first insert above would be
Col_positive Col_Neg Multiplier
S720 S719 2
S719
So far i've tried charindex and split string with also doublesplit which i found here: TSQL: Nested split/parse of string into table (multiple concatenated Tag:Value in one string)
I have a pretty hard request to do in SQL Server 2008, but I'm not able to do the whole...
I have two kind of records :
16HENFC******** (8 numbers after more 'FC')
16HEN******* (7 numbers after more 'EN')
I have to select the * (which are in fact numbers), and add a 0 at the beginning of the second form of record to just have 8 long selected values.
Then I have to insert the result in a empty table.
I think I did the first part which is :
SUBSTRING(SELECT mycolumn1 FROM mytable1 WHERE mycolumn1 LIKE '16HENFC%', 5, 8) ;
In summary,
I have those records in my column :
'16HENFC071052'
'16HEN5130026'
I want to select them and transform them to insert those ones in an other column :
'05130026'
'FC071052'
[EDIT]=>
CREATE TABLE nom_de_la_table
(
colonne1 VARCHAR(250),
colonne2 VARCHAR(250)
)
INSERT INTO nom_de_la_table (colonne1)
VALUES
('16HEN5138745'),
('16HENFC071052v2'),
('16HENFC78942878'),
('16HEN4830026'),
('16HEN7815934'),
('16HENFC74859422'),
('16HEN9687326'),
('16HENFC74889639'),
('16HEN9798556');
[etc...]
So two different types of records, and I want to insert the result of what you did first with just two records in an other column but for the 956 records of my table. And this is the result with the two examples :
'05130026'
'FC071052'
Left-Filling a string is a relatively easy request. Here's an example:
select right(replicate('0',8) + right(test,len(test)-len('16HEN')),8)
from (
select '16HENFC071052' as test
union all
select '16HEN5130026' as test
) z
Use replicate to left-fill your string with the amount of digits you wish to end up with. Append your desired string, in this case, slice your prefix off by taking the right X characters where X = len(target) - len(prefix). Finally, take the right characters of the whole string equal to your desired length.
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...
