Creating a SQL Expression Formula

Post Author: edt11
CA Forum: Formula
I need to due a lookup on name(stored in a different table). I want to display the name result on the report.
I have tried using the following SQL:
SELECT distinct(a.short_name) FROM FUND A, FUND_EXTERNAL BWHERE A.FUND_NUMBER = B.CUSTODIAN_KEY
And I keep receiving an ORA-00936 error (Missing Expression). If there is a way to retrieve this info in a normal formula that would be great as well. But the SQL above gives me the results I am looking for so I didn't exhaust all solutions in the Formula Workshop.
Thanks

SQL Expression Field - Combine Declared Variable With Case Statement

Hello All, I have been using Crystal & Business Objects for a few months now and have figured out quite a bit on my own. This is the first real time I have struggled with something and while I could do this as a Formula Field I would like to know how to do this as a SQL Expression. Basically I want to create a SQL Expression that uses a CASE statement but I wanted to make the code a little more efficient and employ a variable to hold a string and then use the variable in the CASE statement. The expression editor accepts the CASE statement OK but I don't know how to declare the variable. Please assist with the syntax?
This is what I have:
CASE
   WHEN u201CDatabaseu201D.u201DFieldu201D = u2018Hu2019 THEN u2018Hedgeu2019
   WHEN u201CDatabaseu201D.u201DFieldu201D = u2018Pu2019 THEN u2018PVIu2019
   ELSE u2018Noneu2019
END
This is what I want:
DECLARE strVar AS VARCHAR(25)
strVar = u201CDatabaseu201D.u201DFieldu201D
CASE
   WHEN strVar = u2018Hu2019 THEN u2018Hedgeu2019
   WHEN strVar = u2018Pu2019 THEN u2018PVIu2019
   ELSE u2018Noneu2019
END

Hi Todd,
Please use the following for loop; your problem will be solved.
Local StringVar str := "";
Local NumberVar strLen := Length ({Database.Field});
Local NumberVar i;
For i := 1 To strLen Do
       if {Database.Field} <i> = "H" then str := "Hedge"
        else if {Database.Field} <i> = "P" then str := "PVI"
        else str := "None"; exit for
str
Let me know once done!
Thank you,
Ashok

SQL Expression Fields

In crystal report 2008,I create a SQL Expression Fields，but how to write the SQL query in the formula workshop,
Edited by: nylethx1 ye on Jul 23, 2008 9:48 AM

Select count(*) from Table
Your query must return a unique value.
From Don: SQL Expressions were not designed to run SELECT statements. Use a Command object for selects.

SQL Expression field with parameter

Hello,
I am trying to create a SQL Expression Field that will give me the maximum status date of an employee before a certain date entered in parameter.
ex: select max(status_date) from status where status_date < formula field or parameter
Since I can not put a paramter or a formula field in a SQL Expression field, I might need a template or an example of something that works ?
Thank's
Steph
Edited by: Stephanie Charest on Aug 4, 2008 7:59 PM

Ok,
The only way I found to get the maximum status date of an employee with the date entered in parameter was to litteraly put each employee ID, and Status Date in the Detail section.
Then in the select expert create the parameter date.
Then I created a running total field that counts the employees and resets on change of employee sorted by status date.
Then I created a formula that gets all the first occurences of this running total field and if the running total field equals 1, a new formula field shows 1 and if not (2 and more), it shows 0.
But I can't find the way to give me the total that I need for each group sections.
It's ok if the SQL expression field does not work, but I need to find a way to get the max date.
Thank's for your help for the SQL Expression field.

SQL Expression Field Help

Need to create a SQL Expression Field based on this query - or can someone tell me how to do it CR syntax?
SELECT Count("ordhdr"."ACCT_NO")
FROM ordhdr
WHERE (dt_in between '2011-01-01 and '2011-10-31')

create a group, group off of account number.
Your select statement should be close to this.
in Date (2011, 01, 01) to Date (2011, 10, 31)
You can drop your fields into the detail section.
Right click the ordhrd select insert summary, group 1, and change it from sum to count.
You can suppress the details.
The corresponding SQL would look something like this.
SELECT `ordhdr`, `acct_no`, `DT`
FROM `Datasource name`
WHERE (`DT`>=#2011-01-01 00:00:00# AND DT`<#2011-10-31 00:00:01#)
ORDER BY `acct_no`

Sql expressions field option not available in field explorer

Hello:
I would like to create a sql expression field in my report. however when I go to the field explorer panel, a sql expression fields node is not available to create one. Does anybody know why is this not an option?
Thank You Very Much

Also if you are creating based off any stored procedure or View you can't see Sql Exprn under field explorer. I think it is also databse specific. What is the databse you are using ? also what is your datasource ?
Thanks,

Trouble with SQL Expressions

Hello everyone,
I'm having trouble with this SQL expression that works in 8.5, and XI R2 runtime and designer, but I cannot edit the expression. As soon as I open the SQL Expression and click the X-2 check button, the error following
SQL Expression I'm trying to run:
(Select Distinct b1.CandEmploymentType
    from ceistaffing a1
    inner join ceisubmittal b1 on a1.submittalid = b1.ceisubmittalid
Where a1.Staffingchainid = CEIHRPROJECTEDACTUAL."STAFFINGCHAINID"
    and b1.createdate in (Select max(b2.createdate) from ceistaffing a2 inner join ceisubmittal b2 on a2.submittalid = b2.ceisubmittalid where a2.staffingchainid = a1.staffingchainid))
The Errror I Receive After Clicking the X-2 button:
Crystal Reports
Error in compiling SQL Expression :
Failed to retrieve data from the database.
Details: ADO Error Code: 0x
Source: SalesLogix OLE DB Provider
Description: The multi-part identifier "CEIHRPROJECTEDACTUAL.STAFFINGCHAINID" could not be bound.
Native Error: [Database Vendor Code: 181797304 ].
OK
This is the SQL statement passed to the database:
SELECT (Select Distinct b1.CandEmploymentType
from ceistaffing a1
inner join ceisubmittal b1 on a1.submittalid = b1.ceisubmittalid
Where a1.Staffingchainid = CEIHRPROJECTEDACTUAL."STAFFINGCHAINID"
and b1.createdate in (Select max(b2.createdate) from ceistaffing a2 inner join ceisubmittal b2 on a2.submittalid = b2.ceisubmittalid where a2.staffingchainid = a1.staffingchainid))
If I reverse the order of the where clause as follows, I do not get the error
(Select Distinct b1.CandEmploymentType
from ceistaffing a1
inner join ceisubmittal b1 on a1.submittalid = b1.ceisubmittalid
Where CEIHRPROJECTEDACTUAL."STAFFINGCHAINID" = a1.Staffingchainid
and b1.createdate in (Select max(b2.createdate) from ceistaffing a2 inner join ceisubmittal b2 on a2.submittalid = b2.ceisubmittalid where a2.staffingchainid = a1.staffingchainid))
This is the working SQL statement passed to the database.
SELECT (Select Distinct b1.CandEmploymentType
from ceistaffing a1
inner join ceisubmittal b1 on a1.submittalid = b1.ceisubmittalid
Where CEIHRPROJECTEDACTUAL."STAFFINGCHAINID" = a1.Staffingchainid
and b1.createdate in (Select max(b2.createdate) from ceistaffing a2 inner join ceisubmittal b2 on a2.submittalid = b2.ceisubmittalid where a2.staffingchainid = a1.staffingchainid))
FROM   "sysdba"."CEIHRPROJECTEDACTUAL" "CEIHRPROJECTEDACTUAL"
I figured I would just reverse the where clause statements, but then I came to this one that I couldn't get to work:
(Select case when tmp.restartcount = 0 then 'F' else 'T' end from
(Select Count(b.restart) as restartcount from ceistaffing a inner join ceihrprojectedactual b on a.staffingchainid = b.staffingchainid
where a.candcontactid = (Select distinct candcontactid from ceistaffing a2 where a2.staffingchainid = CEIHRPROJECTEDACTUAL."STAFFINGCHAINID")
and b.restart = 'T'
and a.createdate = (Select min(a1.createdate) from ceistaffing a1
               where a1.createdate > (Select max(a3.createdate)
                              from ceistaffing a3
                              where a3.staffingchainid = CEIHRPROJECTEDACTUAL."STAFFINGCHAINID")
               and a1.candcontactid = a.candcontactid)) as tmp )
I've burned an entire day trying to find some solution. Are there any patches out there that will fix this?
I'm running Crystal Report XI Release 2 SP2 - Version 11.5.8.826
Thank you, ...Rob

Okay, to simplify the illustration of the problem Iu2019m facing, Iu2019ve created a bare bones example as described below:
I've created a report that returns all contacts from our "CONTACT" table. On the report, I've created a SQL expression to return a count of all contacts with the similar last name, as shown below:
(Select count(a1.ContactID) from CONTACT a1 where a1.LASTNAME = "CONTACT"."LASTNAME")
When I try to save the SQL expression, I get this error:
Crystal Reports
Error in compiling SQL Expression :
Failed to retrieve data from the database.
Details: ADO Error Code: 0x
Source: SalesLogix OLE DB Provider
Description: The multi-part identifier "CONTACT.LASTNAME" could not be bound.
Native Error: [Database Vendor Code: 205193720 ].
OK
This SQL expression works fine in CRW 8.5, but no luck in XI R2 SP4 - As mentioned above in the thread, this seems to be an issue solely with how XI R2 is parsing the SQL Expression. If I remove the "A1" alias from my expression all is good, but that will not work for some of the more advanced SQL expressions I have that are using joins and sub queries.
What will it take to get this recognized as an issue worthy of a hot fix? I'm at a stand-still here, facing the unfortunate possibility of having to re-architect many of my reports. Please help.
Thank you, ...Rob

I am NOT an expert in Visual Studio but I would guess that when you have build your package, would have a checkbox somewhere to mention SQL 2005 as pre-requisite. something which should
say check for prerequisites for SQL server 2005 express edition??
On this machine, since you have SQL 2008 R2 installed, the check is failing and hence installation?

PL/SQL Expression of button

HI, please help me
how to create PL/SQL expression of button to redirect to another page in the application on Oracle 10 g
in PL/SQL i create this code but can not continue
BEGIN
select password from user where user_name='john';
if password='123' then
in the above page must be redirected to another page
end if;
END;
Edited by: 912303 on Apr 6, 2012 9:47 AM

Is this query the 1st thing you do on the current page?
If so, then one way to do that would be to create a Before Header Branch to redirect to the target page and make the branch condition EXISTS
and enter the query
Select NULL
From user_table
Where user = 'John' and password = '123'

Putting Parameter into SQL Expression or convert to formula Basic or Crystal

Hello,In my old report I got something like thisSELECT MIN(cast("ParDyn"."ParVal" as integer))FROM "result".ParDyn WHERE "ParDyn"."ParNo" = (SELECT Max("Piece"."ParDynNo") FROM "result"."Piece" WHERE "Piece"."RequestNo" = XPARAM1 And "Piece"."PieceNo" = XPARAM2) And "ParDyn"."ParIdent" = 'Trace.Assignment' This report are viewed from VB component - at old VB they read SQL from report, input XPARAM1 and XPARAM2 and put it into report again and the show report.Because now I want to make my aplication I convert this report to use it not only at this old aplication, but with CR Viewer too.I see I can not insert Parameter into SQL Statement, so I need to use Basic or Crystal Formula.I try to make something like this : minimum({ParDyn.ParVal})and {ParDyn.ParNo} = 0of cource zero should be exchange with next statement, but this not working.What I would like to get is only one record, I do not want get whale table into CR engine and then evaluate becouse this report must work on slow connection, so I need take from database only records witch I need. Can someone help me, or show how to insert into formula value as parameter taked from another table dynamicly ?? Best Regards Bartłomiej Jóźwiak

SQL Express 2008 R2 - CREATE DATABASE permission denied in database 'master'

I have created a setup application with SQLEXpress 2008 as a prerequisite. On test SQLExpress installs OK
after the application is installed it must create and install a database using a mixture of SMO and Scripting. I used SMO to add the current user (who is a Windows Administrator) as a Login to the SQL Express server.
Dim l As Login = New Login(srv, My.User.Name)
                l.LoginType = LoginType.WindowsUser
                l.AddToRole("sysadmin")
                l.DefaultDatabase = "MASTER"
                l.Create()
It fails on srv.CreateDatabase with error message "permission denied in database MASTER"
this thread talks about converting the server to single user mode before adding a login
http://social.msdn.microsoft.com/Forums/en-US/sqlexpress/thread/86daf5f5-d333-40b1-ae6f-0da052a96600
how is it possible to scrip this? there is no documentation i can find.
the database must be installed in the ProgramData folder. Is there a permissions issue with this. Do I need to assign permissions to this folder somehow?
bear in mind this will be a remote install and the user expects it work flawlessly.  No manual interventions

if i connect to the sqlexpress instance (local)\SQLEXPRESSS using SQL Management Studio and try to modify the Windows User Login I get the error message:
"User does not have permission to perform this action. (Microsoft SQL Server, Error: 15247)"
how is this possible. it seems to be at an impasse. can't go forward or backward
Now try launching Managenment Studio by right clicking on shortcut and choosing "Run As Adminitstartor".
If above works then you are running on Windows 2008 family OS (Vista, 2k8 or Win7) which has
UAC feature.
If above does not work then you really don't have permission then follow below.
Troubleshooting: Connecting to SQL Server When System Administrators Are Locked Out
Start the instance of SQL Server in single-user mode by using either the
-m or
-f options. Any member of the computer's local Administrators group can then connect to the instance of SQL Server as a member of the
sysadmin fixed server role.

"SQL Expression Fields" branch missing from Formula Workshop/Field Explorer

Hello,
I am using Crystal Reports XI R2 SP3. Some recent information I have seen suggests that I should use a feature called "SQL Expression Fields". If I search the built-in Crystal Report help for "SQL Expressions", on the help pages I see that there is a "SQL Expression Fields" branch in the left pane of the Formula Workshop, just under Formula Fields and just above Selection Formulas (it's unfortunate that I cannot embed a bitmapped screen print of this). The left pane of the Formula Workshop looks like this:
Report Custom Functions
Repository Custom Functions
Formula Fields
SQL Expression Fields
Selection Formulas
Formatting Formulas
However, in my local copy of Crystal Reports the SQL Expression Fields branch does not exist - the left pane of the Formula Workshop looks like this:
Report Custom Functions
Repository Custom Functions
Formula Fields
Selection Formulas
Formatting Formulas
Is there some special patch, add-in or plug-in that's necessary to enable this functionality?
Thanks in Advance,
Bob Gardner

I set up a DSN to a local MS Access database and used it for an ODBC connection. Once connected, the SQL Expression Fields branch was available in Field Explorer and Formula Workshop.
But I am developing reports for an ERP system that uses Oracle 10g databases - I have no choice but to use Oracle 10g databases as data sources for my reports. I am not sure how to set up an ODBC connection to an Oracle database as I have never had to do so - will SQL Expression Fields not work with the native Oracle driver?
Thank you,
Bob Gardner

First time an SQL expression is placed on report a DB SELECT executes

The same problem can be created using the normal Crystal Reports XI Release 2 developer environment and/or code (not only a code issue). I'm using CR XI.
Symptom:
We dynamically auto generate SQL Expressions, Tables, Joins, Formula's and anything through C# and place it onto the Crystal Report through code via run-time user input in a web environment. I recieved a notification from one of my DB admins that crystal reports is causing massive memory consumption via unknown SELECT statements that have no joins and/or WHERE criteria.
Some Detective Work/More Info:
After using Microsoft "SQL Profiler" along with Crystal, I understand what is happening but don't know the "work around" to make Crystal stop executing the following SELECT scenario.
Anytime I create a new "SQL Expression" for the first time and then physically "drag and drop" it onto the report then Crystal is executing a "silent" SELECT statement against the database in the design environment. I'm calling it "silent" because I need MS SQL Profiler to see it happen. I'm guessing that this is used for validation or something but this is causing problems when automatically generating a report in a production environment.
Steps to re-create:
1. Open MS "SQL Profiler" and get it running. (will show Crystal Engine silently executes the SELECTS)
2. Add a new "SQL Expression" to your report.
3. Drag and Drop your new "SQL Expression onto your report
4. You will see that Crystal has created an SQL query and executed it against your database in design environment.
The Problem:
I can see under normal circumstances why you might want this funtionality (if it's actually used for the Crystal Engine to validate your SQL Expression). But, What also makes this functionality horrible is that on my behalf Crystal is creating these SELECT statements and using cross joins which is a major problem in a production environment. As a result, huge record sets are being created on our DB Server. I don't believe that this has any purpose in a production evironment when the cross-joins can create huge amounts of results just for the sake of Crystal Internally validating a new SQL Expression placed onto a report. It would be nice to disable this functionality in production. I don't know a "work around" since these SELECT queries are created on my behalf by the Crystal Engine at design time (via code auto generation in production).
Questions:
Can this functionality be disabled to prevent a production server from incurring the execution of these queries?
Anybody else notice this and have a "work around"?
