Dynamically Delete Entire Columns' Values
Aug 3, 2004
Hello all,
I was wondering if anyone knew of a way to dynamically delete all of the values for a group of columns. What I mean by this is that lets say a table (TableA) has five fields (Field1, Field2, Field3, Field4, and Field5) with 100 rows of data. I want to delete all of the data in Field1, Field2, and Field4. I do not want to delete any of the data in Field3 and Field5. I would then end up with a table with 5 fields and 100 row, but only 2 fields (Field3 and Field5) have data.
The catch is that I can't hardcode the field names of the fields I want to clear out (Field1, Field2, and Field4) into the SQL. This is because if any new fields are eventually added to the table I want them to be cleared out as well without modifying the SQL.
I can hardcode the field names of the fields that I want to keep values for (Field3 and Field5) in the SQL.
If anyone has any idea how to do this, I would greatly appreciate it.
Thanks in advance!

Hi Guys!
This SQL statement, though carefully written to delete only selected rows, deletes the entire A_Shift_Times table:
DELETE FROM A_Shift_Times
WHERE EXISTS (
SELECT 1
FROM
Users
WHERE
(A_Shift_Times.time_in >= CONVERT(DATETIME, '2000-05-29 00:00:00', 102)) AND
((Users.User_Password LIKE N'mrr%') OR (Users.User_Password LIKE N'work%')))
What gives? What am I doing wrong here?

I need to create some kind of log file or table that will record whenever an insert, update or delete is made to any table in a database. I have seen triggers that do this kind of thing on a table level. Can this be done with a trigger or a stored procedure on a database level? If so some kind of example or syntax would be great.
TIA.
Mike

I have a database that has a table that contains basic demographics
•First_name
•Last_name
•Address
•City
•State
•Zip phone
•email
•dob
•etc
•etc
Contained in this table are a lot of duplicate names, and even different addresses. I would like to return an entire row of UNIQUE information based upon “first_name + last name”. Now I know just enough of sql to pull out unique first + last names, but not the entire row based upon this unique information.

I have a script that I use after some amount of data massaging (not shown). I would like to be able to change the
1) denominator value (the value 8 in line 32 of my code) based on how many columns are selected by the where clause:
where left(CapNumber,charindex('_', CapNumber)-1) = 1where capNumber is a value like [1_1], [1_4], [1_6]...[1_9] capNumber can be any values from [1_1]...[14_10] depending upon the specialty value (example: Allergy) and the final number after the equal sign is a number from 1 to 14)
2) I'd like to dynamically determine the series depending upon which values correspond to the specialty and run for each where: left(CapNumber,charindex('_', CapNumber)-1) = n. n is a number between 1 and 14.
3) finally I'd like to dynamically determine the columns in line 31 (4th line from the bottom)
If I do it by hand it's 23 * 14 separate runs to get separate results for each CapNumber series within specialty. The capNumber series is like [1_1], [1_2], [1_3],[1_4], [1_5], [1_6], [1_7], [1_8],[1_9]
...
[8_4],[8_7]
...
[14_1], [14_2],...[14_10]
etc.
Again, the series are usually discontinuous and specific to each specialty.
Here's the portion of the script (it's at the end) that I'm talking about:
--change values in square brackets below for each specialty as needed and change the denom number in the very last query.
if object_id('tempdb..#tempAllergy') is not null
drop table #tempAllergy
select *
into #tempAllergy
from
dbo.#temp2 T
[Code] ....
If I were to do it manually I'd uncomment each series line in turn and comment the one I just ran.

I'm trying to create a query that searches an entire database for keywords inside of the columns for each table within the database. For instance my tables have 2 columns one named ID and the other Permission, I'd like it be able to return all the lines that are associated with that keyword. So if I search "Schedule" it returns all the lines containing that word in it within that database.

I have 2 higher level column groupings of month name and year above my actual date groups. It looks a little weird aligning them left but there is no guarantee that centering them will even allow them to show until I've scrolled right to the middle of the cell width that they occupy.
Is there a feature that comes with, or a well known trick for making them center in the area that is being viewed instead of the potentially very wide cell that they occupy?

I've seen several posts that begin to address this problem, but havenot found a simple, elegant solution that will accomplish this goal.The important part of this solution is that it must be completelydynamic - I have over 40 different categories of devices, each withdifferent fields, and each search will return only one category. Ihave no knowledge of the number or datatype of these field namesbeforehand and must use the sp to dynamically create the table and thentranspose the data.Here is an exampleI have normalized data in this format (this is a simplification)deviceId fieldName fieldValue1 color red1 shape square1 weight(kg) 2.02 shape round2 weight(kg) 1.53 color blue3 shape oval3 weight(kg) 1.0I would like to convert this to the format: (note that it must handlenulls - deviceId 2)deviceId color shape weight(kg)1 red square 2.02 round 1.53 blue oval 1.0Anyone with any thoughts on how best to accomplish this?thanks,Matt

I have a report that displays data based on the last 12 months. Is there a way I can order the columns (header and data) based on the month it was run. eg. If I were to run the report in March, I want the columns to be ordered like this:
MAR, APR, MAY, JUN, JUL, AUG, SEP, OCT, NOV, DEC, JAN, FEB
If run the report in April, I want the columns to be ordered like this:
APR, MAY, JUN, JUL, AUG, SEP, OCT, NOV, DEC, JAN, FEB, MAR
So, the columns in the report are always ordered (12 months backward) based on the month it was run.

I have a situation in SSRS to get the common values between the two columns where the values are sorted comma separated as below.Ex:
ColumnA : abc,cde,efg
ColumnB : cde,xyz,abc
the result in
ColumnC : cde,abc
similarly Column A and B will have n number records. I need to right an expression or the Code function to get the required result in ColumnC. I am using SharePoint Lists as Datasource. Cannot write SQL query to achieve this requirement.

I've got some records like this:
ID_________Jan Feb...........................Dec
0000030257 0 0 0 0 0 0 1 1 1 1 1 0
where each month field has a 0 or 1, depending on if the person was enrolled that month.
I'm being asked to generate a table like this:
ID_________ Start_Date End_Date
0000030257 July 1, 2014 Nov 30, 2014
Is there some slam dunk way to do this without a bunch of If/Then statements?
The editor compressed all my space fields, so the column headers are off in some places.

I have a requirement where in I have to concatenate the fields based on their sequence given in another table along with respect to their lengths.
eg..
Input 1:
Table A: (below are the fields and their respective values, not all fields will have values)
-----------
KSCHL - ZIC0 (KEY)
KOTABNR - 521 (KEY)
MATNR
KUNNR-->1234567890
LIFNR
VKORG-->a234
PRCTR
KUNRE-->4355325363
LIFRE-->88390234
PRODH
---------
Table BSadIt contains the same fields as in table A and will have sequence number in which the concatenation should happen. The length field(LEN) will have corresponding field lengths(pipe delimited) should be considered in concatenation)
---------
KSCHL - ZIC0 (KEY)
KOTABNR - 521 (KEY)
MATNR
KUNNR-->1
LIFNR
VKORG-->3
PRCTR
KUNRE-->2
LIFRE -->4
PRODH
LEN--> 10|10|4|10
Expected Result:
---------------------
KSCHL - ZIC0 (KEY)
KOTABNR - 521 (KEY)
MATNR
KUNNR1234567890
LIFNR

LIFRE0088390234
PRODH
Concat_String12345678904355325363a2340088390234
Note: If the field length given in Table B doesn't match with actual size of the fields then, the field should be filled with 2 left spaces while concatenation.. Eg. In above example say LIFNR value = 88390234(len =icon_cool.gif
then after concat the value should be like below:
12345678904355325363a234 88390234
Note:The fields are not constant..I have around 40 fields like that in which any combination of fields can be possible...eg..
KSCHL - ZIC0 (KEY)
KOTABNR - 521 (KEY)
MATNR -->2
KUNNR--> 4
LIFNR
VKORG-->1
PRCTR
KUNRE
LIFRE --> 3
PRODH
I am not sure which field has the value 1, 2 etc.. and how many fields are forming the combination..It can be sometimes 3/40 fields or it can be 10/40 fields...I have to dynamically get those values and concat...
I can have any number of fields for concatenation..above example is just for 4...it should be dynamic enough to handle any number of fields..

Hi,
I am wondering if someone has some experience with hiding columns in a Matrix report. I have got two details columns: "Yr to Yr Credits Growth? and "Yr to Yr Credits Growth %" and those two columns return only one value "N/A" for the earliest year since there is nothing to compare to. Thus, I don't really need them for the earliest year. On top of detail columns, I have got three matrix groups: matrix1-Year, matrix1-Quarter and matrix-Date. Once those two detail columns are hidden, I would like obviously resize (shrink) those three matrix groups columns to reflect the fact that the detail columns were hidden.
Thanks!

Hi,
I have a sproc that returns somevalues and everything is working fine... and in my reports i am assigning the header data (in a detail column) based on the some feilds in the sproc... and there around 20 feilds that i want to show... but at a given time i am pretty sure that there wont be more than 10 fields that will have data.
So is it possible that show only the columns that have data in it and sometimes if there is less that 5 - 6 fields.. i want to realign the widths in those tables..
any help is appreciated..
Regards
Karen

Basically, I'm given a daily schedule on two separate rows for shift 1 and shift 2 for the same employee, I'm trying to align both shifts in one row as shown below in 'My desired results' section.
Sample Data:
;WITH SampleData ([ColumnA], [ColumnB], [ColumnC], [ColumnD]) AS
(
SELECT 5060,'04/30/2015','05:30', '08:30'
UNION ALL SELECT 5060, '04/30/2015','13:30', '15:30'
UNION ALL SELECT 5060,'05/02/2015','05:30', '08:30'
UNION ALL SELECT 5060, '05/02/2015','13:30', '15:30'
[Code] ....
The results from the above are as follows:
columnAcolumnB SampleTitle1 SampleTitle2 SampleTitle3 SampleTitle4
506004/30/201505:30 NULL NULL NULL
506004/30/201513:30 15:30 NULL NULL
506005/02/201505:30 NULL NULL NULL
506005/02/201513:30 15:30 NULL NULL
My desired results with desired headers are as follows:
PERSONSTARTDATE STARTIME1 ENDTIME1 STARTTIME2 ENDTIME2
506004/30/2015 05:30 08:30 13:30 15:30
506005/02/2015 05:30 08:30 13:30 15:30

I have created dynamic sql to declare variables based on columns from the table and i set values to those variable now here is the issue . i want to check the variable values how do i do that dynamically
drop table test
create table test
(
id varchar(10) not null,
col1 varchar(10) ,
col2 varchar(10)
[Code] .....
Now my next step is verify if the variable is blank or not how do i do that ?
How do i verify all of the columns one after the other .
I am after the statement like this dynamically
-- IF NOT (@col1 = '') THEN set @SQL = @SQL + '[col1] = ' + @col1 + ' '
--IF NOT (@col2 = '') THEN set @SQL = @SQL + '[col2] = ' + @col2 + ' '
I need to check if the columns are blank or not dynamically as i do not want to hard code the column names there.

How to handle this kind of scenario in the SSIS ?

hi,
it is my first post on this forum, please be patient if i miss any important bit of information.
i am transporting data from a legacy system into mssql 2k5 using SSIS.
among those column of a dataset there are 13 columns, all necessary for operational reasons, that i need to ensure data consistance.
i believe i could do this check using the lookup data flow item, but surely there must be a way to do it in a more streamlined fashion.
since column names contain numbers to distinguish the version, eg; col01, col02, col03 .. col13.
i thought i could include the lookup within a loop and use a couple of variables to do this trick, but since i have not done it before i am asking for some sort of guidance from a guru among you folks.
please let me know if further clarification is necessary.
regards,
nicolas

I have created some dynamic sql to check a temporary table that is created on the fly for any columns that do contain data. If they do the column name is added to a dynamic sql, if not they are excluded. This looks like:
If (select sum(Case when [Sat] is null then 0 else 1 end) from #TABLE) >= 1 begin set @OIL_BULK = @OIL_BULK + '[Sat]' +',' END However, I am currently running this on over 230 columns and large tables 1.3 mil rows and it is quite slow. How I can dynamically create a sql script that only selects the columns in the table where there is data in a speedier manner. Unfortunately it has to be on the fly because the temporary table is created on the fly.
