SQL query to linked index server does not work w wildcards - sql

this statement I use in a sproc (where the search phrase 'reiseportal*' is a parameter) does not work with a wildcard, as I recognized:
DECLARE #strSQL NVARCHAR(MAX)
SELECT #strSQL= 'SELECT FileName, path, size, vpath from "GRIP-SERVER"."Web2"..SCOPE() where contains
('SELECT #strSQL=#strSQL + CHAR(39) + CHAR(39)+ 'reiseportal*' + CHAR(39) + CHAR(39)+')'
SELECT #strSQL='SELECT DISTINCT DOC.ID_Kandidat, IDXS.* FROM
OPENQUERY([GRIP-SERVER],'+ CHAR(39) + #strSQL + CHAR(39) +') AS IDXS INNER JOIN
tblK_Dokumente AS DOC
ON DOC.Link = IDXS.[FileName]
ORDER BY ID_Kandidat'
EXEC sp_executesql #statement = #strSQL
these are the contents of the #strSQL variable:
after 1st select:
select FileName, path, size, vpath from "GRIP-SERVER"."Web2"..SCOPE() where
contains(''reiseportal*'')
2nd select:
SELECT DISTINCT DOC.ID_Kandidat, IDXS.* FROM
OPENQUERY([GRIP-SERVER],'select FileName, path, size, vpath from "GRIP-SERVER"."Web2"..SCOPE() where
contains(''reiseportal*'')') AS IDXS INNER JOIN
tblK_Dokumente AS DOC
ON DOC.Link = IDXS.[FileName]
ORDER BY ID_Kandidat'
GRIP-SERVER is the linked Index Server (=Microsoft Server 2003 - our file server).
I don't get it ... it returns results with "reiseportals" but not "reiseportal*" or "reiseportal%". Do you have any hints for me?
Your help is greatly appreciated, thanks a lot!

I found the answer myself.
The problem is not the wildcard, but the string-markers. The index server does not use apostrophes but quotation marks. So the correct SQL should be like:
SELECT DISTINCT DOC.ID_Kandidat, IDXS.* FROM
OPENQUERY([GRIP-SERVER],'select FileName, path, size, vpath from "GRIP-SERVER"."Web2"..SCOPE() where
contains(''"reiseportal*"'')') AS IDXS INNER JOIN
tblK_Dokumente AS DOC
ON DOC.Link = IDXS.[FileName]
ORDER BY ID_Kandidat

How to select into table as string builder instead of using cursor in SQL

I am wondering if there is a faster way to handle the following code in SQL. Currently I am using SQL cursor to do a select and build a string of delimiter values, as a dynamic value of suggestion items?
Here is the snippet of SQL:
begin
set #cursor = cursor for
select top 5 Manufacturer,ManufacturerPartNumber,Description as ManufacturerDescription, CONVERT(money,Price) as Price,fms.Score
from Products_OurProducts_Products_View
open #cursor
fetch next from #cursor
into #CURSOR_Mfr,#CURSOR_Model,#CURSOR_Desc,#CURSOR_Price,#CURSOR_Score
while ##FETCH_STATUS = 0
begin
set #suggestionsStringBuilder += #CURSOR_Mfr + ',' + #CURSOR_Model + ',' + #CURSOR_Desc + ',' + convert(varchar(20),#CURSOR_Price) + ',' + convert(varchar(4),#CURSOR_Score) + '^'
fetch next from #SuggestionsListCursor
into #CURSOR_Mfr,#CURSOR_Model,#CURSOR_Desc,#CURSOR_Price,#CURSOR_Score
end
insert into BASE (Manufacturer, ManufacturerOrig, ManufacturerPartNumber,ManufacturerPArtNumberOrig,ManufacturerDescription, QWDescription, Serial,AssetID,Price,Score,ItemType,MfrFound,ModelFound,trained, SuggestionList,LineNumberIn)
values(#objectORIGMfr,#objectORIGMfr, #objectORIGModel, #objectORIGModel, #objectDescription, #objectDescription, '',#objectAssetID,'0.00',#topMaxScore,'NA','1','0',#trained,#suggestionsStringBuilder,#objectLineNumber)
close #cursor
deallocate #cursor
end
The code above is trying to build a dynamic column of delimiter values such as shown below:
Object Example:
Mfr,
Model,
Price,
Score,
Description,
Suggestions = 'Mfr,Model,Desc,Price^Mfr,Model,Description,Price^
A return model would truly be as follows:
BaseMfr:Fluke,
BaseModel:Tb1,
BaseDescription:'Multi meter item',
BasePrice:120.00,
Suggestions: "Fluke, Tc1, 'Desc', '120.00' ^ 'Fluke', 'T11', 'Desc', 220.00"
Can I do the string builder / cursor section without having to use a looping cursor? The idea behind this is we send in items to be priced. If the item is not found, we then build a list of suggestions to bring back to the user of what they may use in the system or so they can see if there is a typo in the data.
The suggestion list is just the rows found, separating the columns by a "," and separating entities by a "^".
Thanks very much in advance!
Thanks you all for the feedback and I appreciate the help even though I know I had a rough time explaining the question correctly. Thanks to the suggestion from Sean Lange, I was able to be directed in the correct direction and came up with this. Now I will test the performance of it to see if it is better or not. Here is the code:
select
SUBSTRING(
(select top 5
Manufacturer + ',' + ManufacturerPartNumber + ',' + Description +',' + CONVERT(VARCHAR,Price) +',' + CONVERT(varchar,fms.Score) +'^' as [text()]
from Products_OurProducts_Products_View
CROSS APPLY (
select
dbo.FuzzyControlMatch('Flooke', Manufacturer) AS score
) AS fms
order by fms.score desc
FOR XML PATH ('')
), 2, 1000) [Suggestions]
The above code produces the following string:
ARD BROOKE,WB808 10UNF,TORQUE SCREWDRIVER,70.00,50^WARD BROOKE,WB808 1146,TORQUE SCREWDRIVER,70.00,50^WARD BROOKE,WB808 1246,TORQUE SCREWDRIVER,70.00,50^WARD BROOKE,WB808 6UNC,TORQUE SCREWDRIVER,70.00,50^ROKEM TECHNOLOGIES,FIRESET,RC STANDARD,105.00,50^
Now I am not sure if I am handling this the best way, but this is what I was searching for. I will post a comment update to let the feed know if the performance is better or worse.

SQL HTML email showing blank when one table has no results

The following code sends 2 diferent tables based on an sql query through the function sp_send_dbmail , the catch is , if both tables return results , the email shows up without any problem , perfectly. If one of the tables has NO results, the email comes up completly blank.
How can i fix this?
Thanks
declare #tableHTML NVARCHAR(MAX);
set #tableHTML = N'Este foi o resultado de Faturas Emitidas: <br><br><table border ="1">' +
N'<tr><th>Documento</th></tr>' +
cast (( select td = cc.tx
from cc
for xml path ('tr'),type) as nvarchar(max)) +
N' </table><table border ="1"><tr><th>Valor Total Vencido</th></tr>'
+
cast (( select td = fx.tc
from fx
for xml path ('tr'),type) as nvarchar(max)) +
N'</table>';
EXEC sp_send_dbmail
#profile_name ='xx_SqlMail',
#recipients ='ccccc#hotmail.com',
#subject ='Resumo',
#body =#tableHTML,
#body_format='HTML';
I would suspect that part of your query is returning a NULL value. Concatenating any value with a NULL will always result in NULL.
SELECT 'A' + NULL + 'B' will return NULL.
As you are doing multiple concatenations it would mean that if any value is NULL then #tableHTML will be NULL. Try wrapping your selects in an ISNULL().
select ISNULL(td, '') = cc.tx ...
Any table in your concatenation that returns a NULL will make the entire concatenation NULL.
To resolve this, just wrap each section that could potentially be NULL with an ISNULL().
I had a similar issue where I was running two separate queries and building two tables that I wanted to include in the body of the email. One would occasionally return no values and the email would come back blank. Using ISNULL fixed it for me.
See the code below for an example of what I did:
set #tablesHTML = **ISNULL**(#tableOneHTML,'NO RESULTS')
+ **ISNULL**(#tableTwoHTML,'NO RESULTS')
exec XXXXXX.[XXX].[sp_send_dbmail]
#profile_name='Mail'
,#recipients = #EmailRecipients
,#copy_recipients= #EmailCopyRecipients
,#subject = 'Email Subject Here'
,#body = #tablesHTML
,#body_format = 'HTML'

Logic to prepare SQL statements dynamically

So i have a requirement where I need to read through records of all records of a file and insert them into another file if they meet a set of rules which are described in another table as shown below..
A record after it has been read from the first file has to meet all the sequences of at least one Rule to make it eligible to be written into the Second table.
For example once a record is read from CAR file, the rules below have to be checked till all sequences of atleast one rule set is satisfied. For this I was planning to Create a dynamic SQL program something of this sort. But this does not work as Prepared SQL does not support host variables.
If any body can suggest or provide any guidance on how to create SQL statemtns dynamically and check if records satisfy the required rules for them to be entered into the second file, it would be great
So basically what I am looking for is once I select a field from a table, how do I store it somehere to do further validation and checking.
Update
:
Based on the intelligent advice from Danny117, I have come up with the below code:
H Option(*NoDebugIO:*SrcStmt)
D RULEDS E DS EXTNAME(RULESTABLE)
D MAXRUL S 1 0
D MAXSEQ S 1 0
D STMT S 512
D WHERESTMT S 512 INZ('')
D FullSqlStmt S 512 INZ('')
D RULINDEX S 1 0 INZ(1)
D SEQINDEX S 1 0 INZ(1)
D APOS C CONST('''')
/Free
Exec SQL SELECT MAX(RULENO)INTO :MAXRUL FROM RULESTABLE;
Exec SQL DECLARE RULCRS CURSOR FOR SELECT * FROM RULESTABLE;
Exec SQL OPEN RULCRS;
Exec SQL FETCH RULCRS INTO :RULEDS;
DoW (Sqlcod = 0 AND RULINDEX <= MAXRUL);
Exec SQL SELECT MAX(SEQNO) INTO :MAXSEQ FROM RULESTABLE
WHERE RULENO=:RULINDEX ;
DoW (SEQINDEX <= MAXSEQ);
If (Position <> '');
Field = 'SUBSTR('+%Trim(Field)+','+%Trim(Position)+','
+'1'+')';
EndIf;
WhereStmt = %Trim(WhereStmt) + ' ' + %Trim(field)+ ' ' +
%Trim(condition) + ' ' + APOS + %Trim(Value) + APOS;
If (SeqIndex < MaxSeq);
WhereStmt = %Trim(WhereStmt) + ' AND ';
EndIf;
Exec SQL FETCH NEXT FROM RULCRS INTO :RULEDS;
SeqIndex = SeqIndex + 1;
EndDo;
FullSqlStmt = %Trim('INSERT INTO ITMRVAT SELECT * +
FROM ITMRVA WHERE '+ %Trim(WhereStmt));
Exec SQL Prepare InsertStmt from :FullSqlStmt;
Exec SQL EXECUTE InsertStmt;
RulIndex = RulIndex + 1;
EndDo;
This produces SQL statement as shown below which is what I want. Now let me go ahead and look at the other parts of the code.
> EVAL FullSqlStmt
FULLSQLSTMT =
....5...10...15...20...25...30...35...40...45...50...55...60
1 'INSERT INTO ITMRVAT SELECT * FROM ITMRVA WHERE STID = 'PLD' '
61 'AND ENGNO LIKE '%415015%' AND SUBSTR(ENGNO,1,1) = 'R' AND SU'
121 'BSTR(ENGNO,5,1) = 'Y' '
181 ' '
241 ' '
301 ' '
361 ' '
421 ' '
481 ' '
But the issue is now as I mentioned in my comment to Danny, how to handle if a new rule involving second table is specified..
Embedded SQL does allow for 'dynamic statements' in ILE languages. You are able to have a query within a character field and then pass it into the Embedded SQL.
Dcl-S lQuery Varchar(100);
lQuery = 'SELECT * FROM CUST';
EXEC SQL
PREPARE SCust FROM :lQuery;
EXEC SQL
DECLARE SearchCust CURSOR FOR SCust;
//Continue working with cursor..
You may want to just prepare, execute and return a result set:
lQuery = 'SELECT * FROM CUST WHERE ID = ' + %Char(CustID);
EXEC SQL
PREPARE SCust FROM :lQuery;
DECLARE c1 CURSOR FOR SCust;
OPEN c1;
FETCH c1 INTO :CustDS;
CLOSE c1;
Optional extra: You may also want to use field markers (?) in your query.
//'SELECT * FROM CUST WHERE CUSTID = ?';
EXEC SQL OPEN SearchCust USING :CustID;
//'INSERT INTO CUST VALUES(?,?)';
EXEC SQL EXECUTE CUST USING :CustID;
You have to translate the rules into a join statement or a where clause. The join statement is more complex so go that route.
If you were smart (and you are) consider saving the rules as a SQL clause that you can join or use in a where clause. Its infinitely flexible this way a more modern design.
rule 1 / car.year = 1990 and car.engno like '%43243%' and substring(car.vin,12,1) = 'X'
eval statement =
insert into sometable
Select car.* from car
join sysibm.sysdummy1
on car.year = 1990
and car.engno lile '%43243%'
...etc on to rule 2 starting with "OR"
or car.year = PLD
and car.engno like '%1234%'
...etc other rules starting with "OR"
exec immediate statement

SQL Query Optimization taking 20 - 30 secs to run

AND (qh.ConfirmedDate <= #CutOff)
Please help me to optimize it. This query is used in a stored procedure.
This is too long for a comment.
ORs in WHERE and ON clauses are very hard to optimize. Often with a query like this, it is better to construct the query based on the components and use dynamic SQL.
For instance, the condition on #OnlyOpenOrders would be included like this:
declare #sql varchar(max);
set #sql = ' . . .';
declare #where varchar(max);
set #where = 'where . . .';
if (#OnlyOpenOrders = 0) begin
set #where = #where + ' and qh.IsCancelled = 0 and h.IsCancelled = 0'
end;
set #sql = #sql + ' ' + #where;
exec sp_executesql #sql;
You need to have similar logic for all the variables you are using.
There are a couple of things, although as others have said without all the required information such as a full execution plan, and schemas of the tables involved it is mostly guidelines/guesswork;
1.) In this part, it would appear you build a string from QuoteStatusId and StockStatusId in order to compare them;
('Q'+ CAST(Qh.QuoteStatusId AS VARCHAR(3)) + 'S' + CAST(h.StockStatusId AS VARCHAR(3))
IN
(SELECT 'Q'+ CAST(QuoteStatusId AS VARCHAR(3)) + 'S' + CAST(StockStatusId AS VARCHAR(3))
FROM t_VirtualStatusMap
WHERE (#VirtualStatusId IS NULL
OR #VirtualStatusId IN (0,-1) OR VirtualStatusId = #VirtualStatusId)))
If you skipped building the strings, since they are comprised of the same two columns and just compared the two columns directly that may speed things up.
2.) Have you tried adding the index which it suggests in the picture you attached? Without seeing your schema and an execution plan it is hard to suggest appropriate ones but it might be worth adding the one suggested (right click the green writing and it will generate the code to add the suggested index). I would read up on indexes and ensure there is an appropriate index for the query to use. ConfirmedDate seems like an obvious one, as well as all the join keys.
3.) As Gordon suggested using dynamic sql or if you are not comfortable with that - maybe splitting the query out into a few queries and switching between each using an IF statement, could help SQL generate a good plan for each scenario, instead of trying to find a generic plan to work for all cases.

Returning values from dynamic SQL by using sp_executesql with an output variable (Or) Error in appending the variable data at the end name dynamically

I just face a problem while working on a stored procedure,
My situation is as below,
I'm calling a stored procedure inside another stored procedure like for example,
EXEC [SP_ADMIN_INSERT_ITEM_STOCK_DETAILS]
#stk_tran_no = #cash_purchase_no,
#stk_tran_date = GetDate(),
#tran_type = 'Cash Purchase',
#item_code = #item_code,
#quantity = #quantity
Currently in the above code we are passing current date to the parameter #stk_tran_date.
But now I need to pass date to #stk_tran_date by fetching that from some other table like,
select #stk_tran_date = Convert(datetime,cash_purchase_date,103) from Cash_Purchase_14 where cash_purchase_no = 'GOH-9/2014'
If you observe my table name is like Cash_Purchase_14 where 14 is a dynamic value which changes every year, as this is 2014 financial year so it looks like Cash_Purchase_14, next year it will be Cash_Purchase_15.
Because of this i use to write these quires first as string then I'll execute them as shown below,
declare #SQL nvarchar(4000)
set #SQL =N' Declare #cash_purchase_date1 datetime
set #cash_purchase_date1 = (select cash_purchase_date from Cash_Purchase_'+ #Financialyearpart +' where cash_purchase_no = ''' + #cash_purchase_no + ''')
print #cash_purchase_date1'
exec executesql #SQL
But I need the value of the variable #cash_purchase_date1 outside this block like below,
EXEC [SP_ADMIN_INSERT_ITEM_STOCK_DETAILS]
#stk_tran_no = #cash_purchase_no,
#stk_tran_date = #cash_purchase_date1,
#tran_type = 'Cash Purchase',
#item_code = #item_code,
#quantity = #quantity
but it is giving an error like, "declare the variable #cash_purchase_date1"
In Other case i tried like calling the stored procedure in side the string like,
SET #SQL =' Declare #cash_purchase_date1 datetime
set #cash_purchase_date1 = (select cash_purchase_date from Cash_Purchase_'+ #Financialyearpart +' where cash_purchase_no = ' + #qt + #cash_purchase_no + #qt +')
print #cash_purchase_date1
EXEC [SP_ADMIN_INSERT_ITEM_STOCK_DETAILS]
#stk_tran_no = ' + #qt + #cash_purchase_no + #qt +',
#stk_tran_date = #cash_purchase_date1,
#tran_type = ''Cash Purchase'',
#item_code = ' + #qt + #item_code + #qt +',
#quantity = ' + #quantity
exec executesql #SQL
In this scenario the value of #cash_purchase_date1 is not replacing it simply retains the same.
Please help to get the value of the variable outside the block.
Or
How can I append the value 14 at the end of the table name dynamically using a variable.
I Tried like
Declare #cash_purchase_date1 datetime
set #cash_purchase_date1 = cash_purchase_date from Cash_Purchase_+ #Financialyearpart
I think i made the problem bit complicated while explaining. Please help me in solving the issue.
Thanks in advance.
You can return values from dynamic sql by using sp_executesql with an output variable:
declare #SQL nvarchar(4000);
declare #cash_purchase_date datetime;
set #SQL = N'select #cash_purchase_date = cash_purchase_date from Cash_Purchase_' + #Financialyearpart + ' where cash_purchase_no = ''' + #cash_purchase_no + '''';
exec sp_executesql #SQL, N'#cash_purchase_date datetime OUTPUT', #cash_purchase_date = #cash_purchase_date OUTPUT;
I think this will solve your problem.
