I have read about a dozen articles here and I am still stumped with this issue.
I am building a dynamic select statement that will update a view on a monthly schedule.

I have read that others have had problems with this type of truncation and I have tried multiple suggestions but in the end the I am getting capped at 68274 in this code with nvarchar(max). For troubleshooting, I am saving the results of the variables and the len of these variables to a table to eliminate the SSMS cap on the display of strings.
I have tried cast(#varible as nvarchar(max)) on the right side of the = sign. I have changed the data type lengths (as the select that is being built is not that large, it is just large after it has been union for each unique customer)
I am open to any suggestions as I have tried many variations of datatype declarations for these variables.
This is NOT about using a table variable - this is about using a local variable to carry a db address within a dynamic SQL cursor which theoretically would work as follows:
-- Assume the global variables #sql, AnalysisLocation, and #sp_executeSql have been declared.

This creates no syntax errors when compiling the dynamic code, however when calling this procedure: Msg 1087, Level 15, State 2, Line 27
Must declare the table variable "#ServerAndDB_for_pfcAppended".
When I use this type of structure passing the location variable in as a global variable from outside the procedure it accepts it correctly, however as a local variable it seems to default to presuming I intend it to be a table variable.
I do NOT want to create a table variable. Is this an impossible structure?
The error is caused by the fact that you are attempting to have a parametrised table name. This is not possible, and whenever a table name should be a parameter, a dynamic query is used, basically like this:
SET #sql = 'SELECT … FROM ' + #tablename + ' WHERE …'
I think, in your situation the cursor should be taken out of the dynamic query, except for the part that uses the parametrised table name. Something like this should probably do:

I have a table with over 120 columns and need to determine which column is used the least. I tried using sql queries to do this, but found T-SQL a bit simpler.
I tried the following but my count comes out as 0 for every column.
Declare data1 Cursor for select column_name
from information_schema.columns
where table_name = 'repository'
Declare #mField nvarchar(255)
Declare #count int
Open data1;
fetch next from data1 into #mField;
set #count = -1;
while ##fetch_status = 0
begin
select #count = count(#mField)
from repository where tablereference =
'central' and ( #mField!= null )
print #mField+' ' ;
print #count;
Fetch next from data1 into #mField;
end
close data1;
deallocate data1;
You can't count values like this because you are only testing if #mField is NULL. The column name isn't substituted.
COUNT ignores NULLs anyway so if you want to count non-null values, do this:
DECLARE #sql varchar(4000)
SET #sql = 'SELECT COUNT(*) AS Total '
SELECT #sql = #sql + ', COUNT(' + QUOTENAME(column_name) + ') AS ' + QUOTENAME(column_name)
from information_schema.columns
where table_name = 'repository'
SET #sql = #sql + ' FROM repository'
EXEC (#sql)
This queries the table once for all columns
You need to use some dynamic sql in the middle to acheive your aim here.
Declare data1 Cursor for select column_name
from information_schema.columns
where table_name = 'repository'
Declare #mField nvarchar(255)
Open data1;
fetch next from data1 into #mField;
while ##fetch_status = 0
begin
exec ('
declare #count int
select #count = count([' + #mField + '])
from repository where tablereference =
''central'' and ( [' + #mField + '] is not null)
if #count < 10
begin
print ''' + #mField + ' '' ;
print #count;
end
')
Fetch next from data1 into #mField;
end
close data1;
deallocate data1;
Your count(#mField) is a count of the litteral value that happens to be in #mField, its not resolving the field name into COUNT(fldBlah), you would need to use dynamic SQL for that.
Declare data1 Cursor FAST_FORWARD for select column_name
from information_schema.columns where table_name = 'repository'
Declare #mField nvarchar(255)
Declare #SQL varchar(1024)
Declare #results table (col_name varchar(128), non_nulls int)
Open data1;
fetch next from data1 into #mField;
while (##FETCH_STATUS = 0) begin
set #SQL = 'SELECT ''' + #mField + ''', count(' + #mField + ') from repository where tablereference = ''central'''
insert #results
exec(#SQL)
Fetch next from data1 into #mField;
end
close data1;
deallocate data1;
select * from #results
For an output like;
col_name non_nulls
[tablereference] 5
[another_col] 1
Where there are 5 non-null values in column tablereference etc
You need to use IS NOT NULL instead of != NULL
I've been asked to create history tables for every table in a database. Then create a trigger that will write to the history table whenever the primary table is updated.
The history tables have the same structure as the primary table, but with a couple of extra rows ('id' and 'update type')
I've never done anything with triggers before, but I would like to do is dynamically go through the columns in 'Inserted' and construct an insert statement to populate the history table.
However I cannot work out how to read the names of the columns and their individual values.
My half finished trigger currently looks like...
CREATE TRIGGER tr_address_history
ON address
FOR UPDATE
AS
DECLARE #colCount int
DECLARE #maxCols int
SET #colCount = 0
SET #maxCols = (SELECT COUNT(column_name) FROM INFORMATION_SCHEMA.columns WHERE TABLE_NAME = 'Inserted')
PRINT 'Number of columns = ' + CONVERT(varChar(10),#maxCols)
WHILE (#colCount <= #maxCols)
BEGIN
DECLARE #name varchar(255)
SELECT #name = column_name FROM INFORMATION_SCHEMA.columns WHERE TABLE_NAME = 'Inserted'
DECLARE #value varchar(255)
SELECT #value = #name FROM Inserted
PRINT 'name = ' + #name + ' and value = ' + #value
SET #colCount = #colCount + 1
END
PRINT 'Done';
When the trigger runs it just says "Number of columns = 0"
Can anyone tell me what's wrong with :
SELECT COUNT(column_name) FROM INFORMATION_SCHEMA.columns WHERE TABLE_NAME = 'Inserted'
Thanks...
First solution proposed by Beenay25 is good, but you should use affected table instead of 'inserted' pseudotable.
This is:
SELECT #name = column_name FROM INFORMATION_SCHEMA.columns WHERE TABLE_NAME = 'AFFECTED_TABLE'
Instead of 'INSERTED'
Also, you should use dynamic SQL.
This will be a complete working solution:
ALTER TRIGGER [dbo].[tr_address_history]
ON [dbo].[address]
AFTER Insert
AS
DECLARE #ColumnName nvarchar(500)
DECLARE #TableName nvarchar(500)
DECLARE #value nvarchar(500)
DECLARE #Sql nvarchar(500)
Set #TableName='address'
DECLARE ColumnsCursor CURSOR FOR
select column_name FROM INFORMATION_SCHEMA.columns WHERE TABLE_NAME = 'address'
OPEN ColumnsCursor
FETCH NEXT FROM ColumnsCursor into #ColumnName
WHILE ##FETCH_STATUS=0
BEGIN
select * into #tmp from inserted
Set #Sql= 'SELECT #value =' + #ColumnName + ' FROM #tmp'
EXEC sp_executesql #Sql, N'#Value nvarchar(500) OUTPUT', #Value OUTPUT
DROP TABLE #TMP
print '[' + #ColumnName +'='+ ltrim(rtrim(#Value))+']'
FETCH NEXT FROM ColumnsCursor into #ColumnName
END
CLOSE ColumnsCursor
DEALLOCATE ColumnsCursor
The 'inserted' table is a pseudo-table; it doesn't appear in INFORMATION_SCHEMA.
There is the UPDATE() operator for use in triggers:
CREATE TRIGGER trigger_name ON tablename
FOR UPDATE
AS
SET NOCOUNT ON
IF (UPDATE(Column1) OR UPDATE(Column2))
BEGIN
your sql here
END
COLUMNS_UPDATED
UPDATE()
There is a way to do what the questioner requires:
I have made something inside a trigger that tests whether all the columns of a particular table actually participated in an insert to that table. If they did, I later copied them to a history table. If they did not, then rollback and print only complete rows may be inserted into the report table. Perhaps they could adapt this to their needs:
here it is:
[
if exists (select 1 from inserted) and not exists (select 1 from deleted) -- if an insert has been performed
begin -- and we want to test whether all the columns in the report table were included in the insert
declare #inserted_columncount int, #actual_num_of_columns int, #loop_columns int, #current_columnname nvarchar(300),
#sql_test nvarchar(max), #params nvarchar(max), #is_there bit
set #actual_num_of_columns = (
select count(*) from (
select COLUMN_NAME
from INFORMATION_SCHEMA.COLUMNS
where TABLE_NAME = 'renameFilesFromTable_report') as z)
set #inserted_columncount = 0
set #loop_columns = 1
declare inserted_columnnames cursor scroll for -- these are not really the inserted ones, but we are going to test them 1 by 1
select COLUMN_NAME
from INFORMATION_SCHEMA.COLUMNS
where TABLE_NAME = 'renameFilesFromTable_report'
set #params = '#is_there_in bit output'
open inserted_columnnames
fetch next from inserted_columnnames into #current_columnname
select * into #temp_for_dynamic_sql from inserted -- this is necessary because the scope of sp_executesql does not include inserted pseudo table
while (#loop_columns <= #actual_num_of_columns) -- looping with independent integer arithmetic
begin
set #sql_test = '
set #is_there_in = 0
if exists (select ['+#current_columnname+'] from #temp_for_dynamic_sql where ['+#current_columnname+'] is not null)
set #is_there_in = 1'
exec sp_executesql #sql_test, #params, #is_there output
if #is_there = 1
begin
fetch next from inserted_columnnames into #current_columnname
set #inserted_columncount = #inserted_columncount + 1
set #loop_columns = #loop_columns + 1
end
else if #is_there <> 1
begin
fetch next from inserted_columnnames into #current_columnname
set #loop_columns = #loop_columns + 1
end
end
close inserted_columnnames
deallocate inserted_columnnames
-- at this point we hold in two int variables the number of columns participating in the insert and the total number of columns
]
Then you can simply do if #inserted_columncount < #actual_num_of_columns ..........
I did this because i have a sp that inserts 1 complete line to the report table every time it runs. That's fine, but i don't want anyone else touching that table by mistake. not even myself. I also want to keep history. So i made this trigger to keep the history but also to check if an insert was attempted without values for all the columns in the report table, and further down the code it checks if an update or delete was attempted and it rollbacks.
i was thinking of expanding this to allow an update but in which all the columns are set.
this could possibly be done as follows:
if update was attempted,
and exists (
select possibly_excluded.COLUMN_NAME from (
select COLUMN_NAME
from INFORMATION_SCHEMA.COLUMNS
where TABLE_NAME = 'renameFilesFromTable_report') as possibly_excluded
group by possibly_excluded.COLUMN_NAME
having COLUMN_NAME not in (
select COLUMN_NAME
from INFORMATION_SCHEMA.COLUMNS
where TABLE_NAME = 'renameFilesFromTable_report' and
sys.fn_IsBitSetInBitmask(#ColumnsUpdated, COLUMNPROPERTY(OBJECT_ID(TABLE_SCHEMA + '.' + TABLE_NAME), COLUMN_NAME, 'ColumnID')) <> 0)
)
begin
rollback transaction
print 'Only updates that set the values for a complete row are allowed on the report table..'
end

I simply want to create the alter table statement when there is a #FK value and to skip it if it's ''.
Can someone point me in the right direction?
You have to uase an IF ELSE statement.
Also, Formatting the code a little, will make it a LOT easier to read X-)
Replace the WHILE loop with
while ##FETCH_STATUS = 0
Begin
IF #FK <> ''
BEGIN
Set #SQL = N'alter table dbo.'+ #ActTable + ' ADD FOREIGN KEY (' + #FK + ') References DBO.' + #TblRef + '(' + #FK + ')'
Print #SQL
fetch next from M2M_AddFK into #ActTable,#FK,#TblRef
