I have a User_Id column with data DOMAIN\USERID
I need it to be DOMAIN\userid
Whats the (sql server) sql?
Update:
Answer from #David McEwing
update UserTable
set [User_Id] = SUBSTRING( [User_Id], 0, CHARINDEX('\', [User_Id])+1)
+ lower(SUBSTRING( [User_Id], CHARINDEX('\', [User_Id])+1, len( [User_Id])))
SELECT LEFT(User_Id, CHARINDEX('\', User_Id)) -- grabs DOMAIN and '\'
+ LOWER(RIGHT(User_Id,
LEN(User_Id) - CHARINDEX('\', User_Id))) -- concat with lower of userid
FROM MyTable
This should do the trick:
declare #name varchar(50)
set #name= 'DOMAIN\USERID'
select SUBSTRING(#name, 0, CHARINDEX('\', #name)+1)
+ lower(SUBSTRING(#name, CHARINDEX('\', #name)+1, len(#name)))

I'm currently doing a data conversion project and need to strip all alphabetical characters from a string. Unfortunately I can't create or use a function as we don't own the source machine making the methods I've found from searching for previous posts unusable.
What would be the best way to do this in a select statement? Speed isn't too much of an issue as this will only be running over 30,000 records or so and is a once off statement.
You can do this in a single statement. You're not really creating a statement with 200+ REPLACEs are you?!
update tbl
set S = U.clean
from tbl
cross apply
(
select Substring(tbl.S,v.number,1)
-- this table will cater for strings up to length 2047
from master..spt_values v
where v.type='P' and v.number between 1 and len(tbl.S)
and Substring(tbl.S,v.number,1) like '[0-9]'
order by v.number
for xml path ('')
) U(clean)
Working SQL Fiddle showing this query with sample data
Replicated below for posterity:
create table tbl (ID int identity, S varchar(500))
insert tbl select 'asdlfj;390312hr9fasd9uhf012 3or h239ur ' + char(13) + 'asdfasf'
insert tbl select '123'
insert tbl select ''
insert tbl select null
insert tbl select '123 a 124'
Results

CTE comes for HELP here.
;WITH CTE AS
(
SELECT
[ProductNumber] AS OrigProductNumber
,CAST([ProductNumber] AS VARCHAR(100)) AS [ProductNumber]
FROM [AdventureWorks].[Production].[Product]
UNION ALL
SELECT OrigProductNumber
,CAST(STUFF([ProductNumber], PATINDEX('%[^0-9]%', [ProductNumber]), 1, '') AS VARCHAR(100) ) AS [ProductNumber]
FROM CTE WHERE PATINDEX('%[^0-9]%', [ProductNumber]) > 0
)
SELECT * FROM CTE
WHERE PATINDEX('%[^0-9]%', [ProductNumber]) = 0
OPTION (MAXRECURSION 0)
output:
OrigProductNumber ProductNumber

RichardTheKiwi's script in a function for use in selects without cross apply,
also added dot because in my case I use it for double and money values within a varchar field
CREATE FUNCTION dbo.ReplaceNonNumericChars (#string VARCHAR(5000))
RETURNS VARCHAR(1000)
AS
BEGIN
SET #string = REPLACE(#string, ',', '.')
SET #string = (SELECT SUBSTRING(#string, v.number, 1)
FROM master..spt_values v
WHERE v.type = 'P'
AND v.number BETWEEN 1 AND LEN(#string)
AND (SUBSTRING(#string, v.number, 1) LIKE '[0-9]'
OR SUBSTRING(#string, v.number, 1) LIKE '[.]')
ORDER BY v.number
FOR
XML PATH('')
)
RETURN #string
END
GO
Thanks RichardTheKiwi +1
Well if you really can't use a function, I suppose you could do something like this:
SELECT REPLACE(REPLACE(REPLACE(LOWER(col),'a',''),'b',''),'c','')
FROM dbo.table...
Obviously it would be a lot uglier than that, since I only handled the first three letters, but it should give the idea.
I have a database with several tables and I need to search every varchar column across the database, for columns that simultaneously contain lower and upper case characters.
To clarify:
If one column contains helLo the name of the column should be returned by the query, but if the column values only contain either hello or HELLO then the name of the column is not returned.
Let's exclude all UPPER and all LOWER, the rest will be MIXED.
SELECT someColumn
FROM someTable
WHERE someColumn <> UPPER(someColumn) AND someColumn <> LOWER(someColumn)
EDIT:
As suggested in comments and described in detail here I need to specify a case-sensitive collation.
SELECT someColumn
FROM someTable
WHERE someColumn <> UPPER(someColumn) AND
someColumn <> LOWER(someColumn)
Collate SQL_Latin1_General_CP1_CS_AS
It sounds like you are after a case sensitive search, so you'd need to use a case sensitive collation for there WHERE clause.
e.g. if your collation is currently SQL_Latin1_General_CP1_CI_AS which is case insensitive, you can write a case sensitive query using:
SELECT SomeColumn
FROM dbo.SomeTable
WHERE SomeField LIKE '%helLo%' COLLATE SQL_Latin1_General_CP1_CS_AS
Here, COLLATE SQL_Latin1_General_CP1_CS_AS tells it to use a case sensitive collation to perform the filtering.
I think I understand that you want to find any varchar column with mixed case data within it?
If so, you can achieve this with a cursor looking at your column types, which then executes some dynamic SQL on the varchar columns it finds to check the data for mixed case values.
I thoroughly recommend doing this on a non-production server using a copy of your database, not least because you need to create a table to deposit your findings into:
create table VarcharColumns (TableName nvarchar(max), ColumnName nvarchar(max))
declare #sql nvarchar(max)
declare my_cursor cursor local static read_only forward_only
for
select 'insert into VarcharColumns select t,c from(select ''' + s.name + '.' + tb.name + ''' t, ''' + c.name + ''' c from ' + s.name + '.' + tb.name + ' where ' + c.name + ' like ''%[abcdefghijklmnopqrstuvwxyz]%'' COLLATE SQL_Latin1_General_CP1_CS_AS and ' + c.name + ' like ''%[ABCDEFGHIJKLMNOPQRSTUVWXYZ]%'' COLLATE SQL_Latin1_General_CP1_CS_AS having count(1) > 0) a' as s
from sys.columns c
inner join sys.types t
on(c.system_type_id = t.system_type_id
and t.name = 'varchar'
)
inner join sys.tables tb
on(c.object_id = tb.object_id)
inner join sys.schemas s
on(tb.schema_id = s.schema_id)
open my_cursor
fetch next from my_cursor into #sql
while ##fetch_status = 0
begin
print #sql
exec(#sql)
fetch next from my_cursor into #sql
end
close my_cursor
deallocate my_cursor
select * from VarcharColumns
You can check the hash compared to its upper and lower values... here is a simple test:
declare #test varchar(256)
set #test = 'MIX' -- Try changing this to a mix case, and then all lower case
select case
when hashbytes('SHA1',#test) <> hashbytes('SHA1',upper(#test)) and hashbytes('SHA1',#test) <> hashbytes('SHA1',lower(#test))
then 'MixedCase'
else 'Not Mixed Case'
end
So using this in a table... you can do something like this
create table #tempT (SomeColumn varchar(256))
insert into #tempT (SomeColumn) values ('some thing lower'),('SOME THING UPPER'),('Some Thing Mixed')
SELECT SomeColumn
FROM #tempT
WHERE 1 = case
when hashbytes('SHA1',SomeColumn) <> hashbytes('SHA1',upper(SomeColumn)) and hashbytes('SHA1',SomeColumn) <> hashbytes('SHA1',lower(SomeColumn)) then 1
else 0
end
I have a sql query to form a parent/child structure to a tree-like view, the outcome is like this:
lvl1a
lvl1a/lvl2a
lvl1a/lvl2b
lvl1b/lvl2a/lvl3a
lvl1c
lvl1d/lvl2a/lvl3a/lvl4a
...
the query itself doesn't have a limited range, for instance, if i only want to get this tree-like view for the first and second level
can someone modify the sql query to add such function? tks
;with cte as
(
select
labelID,
Title,
ParentLevel,
cast(Title as varchar(max)) as [treePath]
from TestTable
where ParentLevel = 0
union all
select
t.labelID,
t.Title,
t.ParentLevel,
[treePath] + '/' + cast(t.Title as varchar(255))
from
cte
join TestTablet on cte.labelID = t.ParentLevel
)
select
labelID,
Title,
ParentLevel,
[treePath]
from cte
order by treePath
All we did here was add lvl 0 for the first part of the union in the CTE
then increment it by 1 each time the recursion occurs (after the union all)
then add a where clause to the select to eliminate levels beyond 2.
Though I find it odd this works since t isn't aliased in your code...

This is a T-SQL related question. I am using SQL Server 2012.
I have a table like this:
I would like to have output like this:
Explanation:
For each employee, there will be a row. An employee has one or more assignments. Batch Id specifies this. Based on the batch Id, the column names will change (e.g. Country 1, Country 2 etc.).
Approach so far:
Un-pivot the source table like the following:
select
EmpId, 'Country ' + cast(BatchId as varchar) as [ColumnName],
Country as [ColumnValue]
from
SourceTable
UNION
select
EmpId, 'Pass ' + cast(BatchId as varchar) as [ColumnName],
Pass as [ColumnValue]
from
SourceTable
which gives each column's values as rows. Then, this result can be pivoted to get the desired output.
Questions:
Is there a better way of doing this?
At the moment, I know there will be fixed amount of batches, but, for future, if I like to make the pivoting part dynamic, what is the best approach?
Using tools like SSIS or SSRS, is it easier to handle the pivot dynamically?
Screw doing it in SQL.
Let SSRS do the work for you with a MATRIX. It will PIVOT for you without having to create dynamic SQL to handle the terrible limitation of needing to know all the columns.
For your data, you would have EMP ID as the ROW Group and PASS as your column grouping.

There are many possible solutions to achieve what you want (search for Dynamic Pivot on multiple columns)

I have a database with some tables in it and I want to make dynamically generated insert and select statements without the need to use the case statement in the select clause for each table.
The select statement is quite easy, the challenge is with the insert one because I have to deal with each column and its data type. I managed to overcome it by means of a case statement, but I think it's hard working for tables with lots of columns and for databases with many tables.
I wish it was possible to change hardcoded table and column names for each table and column I need the dynamically generated SQL command.
I worked out in the following select statement for the given tables of the database (testDB) I have:
use testDB;
go
set dateformat dmy;
select
'select * from ' + s.name + '.' + t.name + ';' as cmd_select,
'insert into ' + s.name + '.' + t.name + ' (' +
stuff(( select ', ' + column_name
from information_schema.columns
where table_name = t.name and ordinal_position > 1
order by ordinal_position
for xml path(''), type).value('.', 'nvarchar(max)'),
1, 2, '')
+ ') values (' +
case t.name
when 'Person' then '''xxx'''
when 'WeightHistory' then '0.0, ''' + convert(varchar, current_timestamp, 103) + ''', ''' + left(convert(varchar, current_timestamp, 108), 5) + ''', 1'
when 'WorkTime' then '''' + convert(varchar, current_timestamp, 103) + ''', ''' + left(convert(varchar, current_timestamp, 108), 5) + ''', 1, null'
when 'TimeReference' then '''07:00'', ''' + convert(varchar, current_timestamp, 103) + ''', null'
end
+ ');'as cmd_insert --,
--t.lob_data_space_id
--, s.name, t.name, *
from sys.tables as t
inner join sys.schemas as s on t.schema_id = s.schema_id
where t.lob_data_space_id = 0; /* tables that don't have LOB columns (sysdiagrams, varchar(max), xml, etc.) */
What exactly I want to know is:
Is there a better way of making the dynamically generated insert statement without using a case statement for each table and column of the database?
