I have been using a standard block of TSQL for auditing of various tables for some time now. However I now have a problem when running the trigger on a new table: "Error converting data type varchar to numeric". This occurs when running the EXEC (#sql) line. I've determined that the code for #sql is:
insert Audit_AppointmentsWS
(Type,
TableName,
PK,
FieldName,
OldValue,
NewValue,
UpdateDate,
UserName)
SELECT 'U',
'AppointmentsWorkshop',
+convert(varchar(100), coalesce(i.UniqueID,d.UniqueID)),
'[JobHours]',
convert(varchar(1000),d.[JobHours]),
convert(varchar(1000),i.[JobHours]),
'20220816 12:32:43:410',
'DELLXPS\ian'
from #ins i full outer join #del d on i.UniqueID = d.UniqueID where ISNULL(i.JobHours],'') <> ISNULL(d.[JobHours],'')
I've tried deleting the trigger & the audit table and then recreating them but no joy. I've also tried copying an existing trigger and just changing the table details but I still get the same error. I'm completely stumped on this and would appreciate some feedback. Many thanks in advance!
Here is the trigger:

Well I finally figured it out. The error is being generated with columns of data type 'decimal' and it is down to the ISNULL section of the last SELECT. I've fixed it by checking for the decimal type and then using the following code (which included a zero rather than an empty sting):
+ ' where ISNULL(i.[' + #fieldname + '],''0'') <> ISNULL(d.[' + #fieldname + '],''0'')' --Skip identical values and excludes NULLS vs empty strings
Hi I have the following dyanmic stored procedure which returns a normal result set at the end however crystal reports is not returning any fields along with it might anyone have an idea what is wrong.
When I run the proc in studio management it works fine. This is a report using the sap version of crystal in case that makes a difference.
I would normally output the results to excel and it runs correctly but for crystal its not allowing me to select any fields in the field explorer.

Weird I copied the entire proc and declared the date from and date to elements and it worked fine. So why when it being called from a stored proc is it working ok.
If the stored procedure does not return any data Crystal Reports won't be able to show you the columns. Make sure it returns the data.
Anyways, you can always try to remove the stored procedure and add it again in the database assistant. Crystal Reports is not very good updating the fields when you use a stored procedure, or at least it wasn't in older versions.
I am attempting to use dynamic sql to select a value based on a field. I have a table of field references I am using for the column names. What I am having troubles with is of course the dynamic sql. My return result is (SELECT ecoa_code FROM CRA_METRO2_BASE WHERE id = 568470) for example. But I really want it to run that select statement. Executing only returns the last row.
DECLARE #BaseCol VARCHAR(250)
SELECT
#BaseCol = '(SELECT ' + FR_base.field_name + ' FROM CRA_METRO2_BASE WHERE id = ' + CONVERT(VARCHAR(15), B.id) + ')'
FROM CRA_INNOVIS_AUDIT_ERROR_FIELDS E
LEFT JOIN CRA_METRO2_BASE B
ON B.id = E.base_id
LEFT JOIN CRA_METRO2_FIELD_REF FR_base
ON FR_base.id = E.base_field_ref
WHERE E.audit_id = #audit_id
EXEC(#BaseCol)
I am not sure I understand your premises correctly and without a mock-up...; so please take this answer with a grain of salt:)

So I used my above query and now I am using a CTE to build my basic result list. And in my cte I create update statements which then are all put into a temp table.
I extract the update statements and execute them on the temp table. And walla, I have my results!
IF(OBJECT_ID('tempdb..#Temp') IS NOT NULL)
BEGIN
DROP TABLE #Temp
END
CREATE TABLE #Temp

I have created stored procedure which creates pivoted table as below. The problem is that it doesn't work as expected because it doesn't change nulls to zeros. Could You please show me the right direction?
create procedure sp_system_counts
as
declare #columns nvarchar(max)
declare #columnscondition nvarchar(max)
declare #query nvarchar(max)
select distinct systemgroup, systemgroupsortorder into #temp_table_system_group
from systemgroups
where systemgroup not like 'N/A'
order by systemgroupsortorder
select #columns = isnull(#columns + ',', '') + '[' + convert(varchar, systemgroup) + ']' FROM #temp_table_system_group
select #columnscondition = + isnull(#columnscondition + ' or ', '') + '[' + convert(varchar, systemgroup) + '] <> 0' FROM #temp_table_system_group
--select #columns
create table #temp_systems (
systemid int,
systemnane varchar(max),
region varchar(50),
systemgroup varchar(50),
remsid int,
remscode int)
insert into #temp_systems
select distinct sy.systemid, sy.systemname, co.region, syg.systemgroup, re.remsid, re.remscode
from systems sy
inner join servers se on sy.systemid = se.systemid and sy.systemid = sy.systemid
inner join rems re on se.remsid = re.remsid
inner join cities ci on re.cityid = ci.cityid
inner join countries co on ci.countryid = co.countryid
inner join systemmodels sym on sy.systemmodelid = sym.systemmodelid
inner join systemtypes syt on sym.systemtypeid = syt.systemtypeid
inner join systemgroups syg on syt.systemgroupid = syg.systemgroupid
where syg.systemgroup not like 'N/A'
order by syg.systemgroup
set #query = '
select region, ' + #columns + '
from (
select distinct region, systemgroup, cnt = isnull(count(systemid),0) from #temp_systems
group by region, systemgroup
with rollup) p
pivot (sum (cnt) for systemgroup in (' + #columns + ')) as asd
where (' + #columnscondition +')'
execute(#query)
drop table #temp_table_system_group
drop table #temp_systems
I'm not sure, about logic implemented here, but may be it will help, if you change:
select #columns = isnull(#columns + ',', '') + '[' + convert(varchar, systemgroup) + ']' FROM #temp_table_system_group
select #columnscondition = + isnull(#columnscondition + ' or ', '') + '[' + convert(varchar, systemgroup) + '] <> 0' FROM #temp_table_system_group
to
select #columns = isnull(#columns + ',', '') + 'isnull(' + quotename(convert(varchar, systemgroup)) + ', 0) as ' + quotename(convert(varchar, systemgroup)) FROM #temp_table_system_group
select #columnscondition = + isnull(#columnscondition + ' or ', '') + 'isnull(' + quotename(convert(varchar, systemgroup)) + ', 0) <> 0' FROM #temp_table_system_group
i.e. doing isnull(.., 0) over pivoted data, not before pivoting
I have a script that creates and populates a bunch of tables from data we receive as
text files. After loading the data into sql server 2008, I want to add indexes. The cut-and-paste-created script I'm using is shown below.
Is
there a way in TSQL to create a function that will generate and then
evaluate the DDL commands? The function would take parameters
of table name, column name(s) and clustered/not. If there would have
to be a separate function for 1 column/2 column indexes, I'd still
be interested.
I'm envisioning something like:
hypotheticalFunction('clustered', 'precCdaEarn', 'account', 'seq')
hypothericalFunction('nonClustered', 'flats', 'vendorAcct')
and that would check if an acct called "idx_acct_seq" exists on table
precCdaEarn, and drop it if so, then create it as clustered index. (dropping it just
in case i change the definition). And create/recreate a nonclustered index on dbo.flats named "idx_vendorAcct"
========= this is what have now using cut & paste, apologies for the erratic spacing ==============
IF EXISTS (Select 'X'
FROM sysindexes
WHERE id = (SELECT OBJECT_ID('precCdaEarn'))
and name = 'idx_account_seq')
DROP index precCdaEarn.idx_account_seq
Create nonclustered index idx_account_seq
ON precCdaEarn(account, seq)
;
IF EXISTS (Select 'X'
FROM sysindexes
WHERE id = (SELECT OBJECT_ID('acct'))
and name = 'idx_c_precAcct_precMod')
DROP index acct.idx_c_precAcct_precMod
CREATE CLUSTERED INDEX index idx_c_precAcct_precMod
ON acct(precAcct, precMod)
AFAIK you cannot create a function for this, but with a stored procedure it's no problems.
Something like:
IF(OBJECT_ID('PRC_CREATE_INDEX', N'P') IS NOT NULL)
DROP PROCEDURE PRC_CREATE_INDEX
GO
