Now my requriement is i want count of alerts that is when alert option value of the fieldname from first table matches that particular column value then count of alert comes
i.e is ChildrenBoth:Yes is alert if this matches in second table ChildrenBoth column then it is alert count of alert will be 1 and soon as per first table alerts .I have worked on this using dynamic query by getting alerts filednames but not able to get
option values
i worked
Declare @lststr varchar(max)
set @lststr=(select FieldName + ',' from Table_Form46_MasterInfo_Log where Alert='ON' for xml path(''))
print @lststr
Not sure about your requirement, it seems that you want to get AlertOptionValue count from the second table and show the count ?
If so , not sure whether it is the best way , but you could try cursor.
Below is my sql.
First my table.
Masterinfo_Log
InfoId FieldName AlertOptionValue
1 ChildrenBoth Yes
2 ChildrenAllowedTelephone As and when required
3 FrequencyManagementCommitteMeeting Monthly
Full_InspectionForm
inspect_id ChildrenBoth ChildrenAllowedTelephone FrequencyManagementCommitteMeeting
1 Yes As and when required Monthly
2 No empty yearly
3 Yes empty yearly
4 Yes As and when required yearly
CREATE TABLE #Temp --declare a template table to store the result
(
fieldName nvarchar(200),
optionValue nvarchar(200),
alertCount int
)
Declare @fieldName nvarchar(200),@optionValue nvarchar(200),@alertCount int, @sql nvarchar(max)
-- declare @fieldname to store fieldname, @optionValue to store alterOptionValue, @alertCount to store alertCount
declare infolog_cursor CURSOR FOR --declare a cursor
Select FieldName , AlertOptionValue
from Masterinfo_Log;
open infolog_cursor --open the cursor
fetch next from infolog_cursor -- fetch the first row and store the value to @fieldName,@optionValue
into @fieldName,@optionValue
while @@FETCH_STATUS = 0 --loop through Masterinfo_Log
begin
set @sql = 'insert into #Temp select @fieldnameInner as fieldname, @optionValueInner as alertOptionValue ,(select count(*) from Full_InspectionForm where '+@fieldName+'=@optionValueInner) as alertCount '
-- insert into the temp table optionValue, fieldname and count of alert using dynamic sql
execute sp_executesql @sql,N'@optionValueInner nvarchar(200),@fieldnameInner nvarchar(200)',@optionValueInner=@optionValue,@fieldnameInner=@fieldName
fetch next from infolog_cursor
into @fieldName,@optionValue
end
close infolog_cursor; --close the cursor
deallocate infolog_cursor
select * from #temp --select the final result
drop table #temp --drop the temp table
The result.
fieldName optionValue alertCount ChildrenBoth Yes 3 ChildrenAllowedTelephone As and when required 2 FrequencyManagementCommitteMeeting Monthly 1
Here I assume all your optionvalue is of type varchar , if not , you should manually convert int to varchar.
