SQL Expression Fields

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 Fields button not visible in Field Explorer

    Hi,
    On my Crystal Reports installation I can see the button SQL Expression Fields in Field Explorer but it is not visible on client's installation.
    How do I make it visible? I need to create a new report with SQL query for client.
    Thanks,

    Commands are intended to replace the standard linked tables that must users are accustomed to.
    I suppose Commands would be considered an "advanced" feature, considering that they require the developer to be able to hand write SQL (our at least copy it from another SQL editor).
    If you are comfortable writing reading, writing & editing SQL, Commands will open a the door to a whole new level of control when it comes to creating your data sets.
    The biggest problem w Commands is also it's greatest strength... If you're using a Command, CR will assume that you know what you're doing and will not try to rewrite or optimize your SQL in the background. You write it, CR sends it. That means if you write crappy SQL, CR will send your crappy SQL to the db server...
    It also means that you can use join types that aren't available in CR and use sub-queries in in your SQL... Basically anything you can do in the db's native editor.

  • SQL Expression fields do not display when no records are returned

    I have a report that uses SQl expression fields to summarize in the Report footer.  When the main report does not contain any records the SQL expression fields are blank.
    Is there a way to force these SQL expression fields to be evaluated evn when the main report does not contain any records.
    Thanks

    Hi,
    You can try this :
    Under Report Options, check "Convert Database Null values to Default".

  • Passing a variable to an SQL Expression Field

    Is it possible to pass a value or variable to an SQL Epression field?  I want to sum the values of open invoices for a particulat customer and want to do this using an SQL Expression Field.  I need this sum in a  subreport and since I can not put a subreport in a subreport I want to do it using an SQL Expression.
    Thanks.
    Ralph

    That would require a SELECT statement in the expression and they really are not designed to do that.
    If you can't do this client side write a stored procedure then you have full control and CR is just used to display the data.

  • Select Expert or SQL Expression Fields help

    I am trying to do something I would consider very simple but can figure it out.
    I have two tables.  FDC_Trips & Facility.  On the report I can get the FDC_Trips.DivertedbyFacility field to populate a number value because that field is an integer.  But we need the name to show up.  That field is the ID (foreign key) of a Facilty which matches with the field Facility.Code.  Instead of it displaying the DivertedbyFacility number/ID I would like it to be able to show the Facility.Name value.  If I place the filed Facility.Name field on my report it is blank. 
    How can I write a where clause to query the Name of the Facility where the Facility.Code = FDC_Trips.DivertedbyFacility?
    Do I use the Select Expert or SQL Expression Fields.
    Please advise.

    Actually you'll use the Links tab in the Database Expert. If CR did it's stupid auto linking thing... delete them. It usually get's it wrong.
    Now just link the fk field in FDC_Trips to the pk field in Facility. Once you have that done you'll be able to simply drop Facility.FacilityName directly onto the report.

  • Sql expression fields in subreports (CR XI)

    Is it normal that the sql expression fields don't show up in a subreport?
    I don't see any. Does anyone know how? Thanks!

    Sorry for the delay getting back to you all.
    I set up a report against the xtreme database sample. Added the Customer table, and put the columns "Customer ID" and "Customer Name" on the report. I then created a new SQL Expression and entered the following:
    ( SELECT SUM(`Orders`.`Order Amount`) FROM `Orders`
      WHERE `Orders`.`Customer ID`=`Customer`.`Customer ID`)
    I could save the new SQL Expression, which is farther than I got in the real report. I added the SQL Expression field to the report. But when I try to preview the report, I get an error:
    Error in compiling SQL Expression :
    Failed to open a rowset.
    Details: ADO Error Code: 0x800004005
    Source: Microsoft JET Database Engine
    Description: Unspecified Error
    Native Error: 62411
    I suspect that's the MS Access version of the error I was getting with MySQL.

    V361 is mistaken, SQL Expression fields are available in CRXI.
    As with previous versions though, it turns off depending upon the type of database and connectivity used.
    Try using a real SQL database, or if MS Access, set up an ODBC connection to the database.
    In the future include your database in your post to avoid guess work on our part.

  • SQL expression field is not displayed on the page header if no records

    Hello
    I'm creating a quite simple report. In this report I've got a SQL expression field which returns a DateTime
    I display this field on the page header section.
    Everything is working fine except when my principal query doesn't return any records my SQL expression field is not displayed. It doesn't seem to be evaluated.
    So, I would display this field even if my Details Section doesn't contains any record.
    I hope you understand what I mean.
    Can someone help me?
    thanks

    Hello,
    I thought about creating a formula but the value I need is stored in a database.
    So i created a simple SQL expression field.
    SELECT CONVERT(DATE,j_1) FROM VW_STD_DATEFIXING
    And this expression doesn't have any dependencies.

  • 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 Expression Fields not showing

    Hello,
    I want to use "SQL Expression Fields", however, it doesn't appear in the Field Explorer.
    The only options that appear in my Field Explorer are:
    - Database Fields
    - Formula Fields
    - Parameter Fields
    - Running Total Fields
    - Group Name Fields
    - Special Fields
    I am connecting to Oracle 10g Rel.2 with ODBC.
    I have no problems creating reports with queries that access the database.
    Do you have any idea about why the option doesn't appear?

  • "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,

  • Sql expression fields - odbc drivers

    We are using Crystal 2008 with SAP ECC 6.0, and the database is sql server 2005. We had Integration kit installed. We have developed few reports with this one from ECC 6.0.
    My problem is, I am not able to see the SQL EXPRESSION FIELDS in the FIELD EXPLORER of CR 2008. From the replies for my
    previous postings in other forums here and from the feed back of Don Williams, I understood there is a problem with odbc drivers.
    I checked trying with new report and tried using ODBC(RDO) but found no drivers. The ODBC data source window showing "dBASE Files, Excel Files & MS Access Database" in the data source Names field.
    Even from my machine, I checked the ODBC drivers and found only the above three were present in the user DSN tab of ODBC data source administrator window. Shall I have to add ODBC drivers for SQL Native client OR SQL server OR both (FROM THE DRIVERS TAB)?
    Will there be any other ODBC is required for SAP INTEGRATION?
    What are the steps to resolve this and to activate and use the drivers? so that I can see SQL Expression fields & also "Show sql query".

    Hi,
    So by establishing the connectivity through the proper transports and authorizations done to CRM, can I build
    single report by getting the data from two tables one from ECC and another from CRM?
    >> which then means for SSO you need to configure 2 SAP systems on the BusinessObjects Server
    And one more question, If I could not succeed in getting the connectivity through the proper transport & authorization to
    CRM, (lack of basis resources) then can I use BAPI / RFC'S to pull the data from CRM into ECC and then into CRYSTAL(as, ECC is working fine with crystal through the integration kit)? Is it a good practice? Thanks in advance.
    >> for CR then the ECC system would become the single point of entry. sure - that would work as well - but shoulnd't be necessary

  • 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 Command/SQL Expression Fields

    CR XI R2
    Hi All,
    Here's the situation.
    There is an SQL table of lookup codes.  The columns in the table are "FIELD", "VALUE", and "DESCR".
    The data looks like
    CRA_TYPE      RV     Receiving
    CRA_TYPE      AJ      Adjustment
    CUST_TYPE    MD     Medical
    CUST_TYPE    RT      Retail
    The main datatables contain a "VALUE" in a particluar "FIELD" and I need to be able to retrieve the appropriate "DESCR" to output on the report.
    There is a stored procedure that takes 'FIELD" and "VALUE" and selects "DESCR" but I can't figure out how to set it up as a formula field and pass parameters to it for each line.
    It is basically
    SELECT DESCR FROM tbLookUp WERE [FIELD]=@FIELD AND [VALUE]=@VALUE
    The "FIELD" parameter would be static (in this case "CRA_TYPE") and the "VALUE" parameter would be the value of the CRA_TYPE field in each datarow.
    I can't just use the "VALUE" since more than one field might have the same "VALUE" but a different "DESC".  Only the combination of "FIELD" and "VALUE" is unique.
    I've been playing with SQL Commands and SQL Expression Fields with no success.  There aren't a lot of samples to look at especially the SQL Expression Fields.
    I could create a new stored procedure that would just send in the translation but I don't want to create a stored procedure for every report and almost all the reports will need a similiar transaction scenario.
    Any help would be greatly appreciated.  
    Thanks in advance.
    Larry

    Yes, I am pretty familiar with Crystal, at least in the routine stuff and pretty good in VB and SQL.
    In normal SQL I would retrieve it with a join to the LookupTable.
    like: JOIN tbLookUp ON tbLookUp.FIELD = 'CRA_TYPE' AND ( tbLookUp.[value] = tbCRA.CRA_TYPE)
    and then just add to the SELECT statement:   tbLookUp.DESCR
    However, I can't find anyway to use the Database Expert to add the FIELD='CRA_TYPE" to the linking process
    I was hoping the "SQL Expression Fields" might hold the answer but the documentation and examples on their use is pretty slim.
    I was hoping for a way to run something like:  SELECT DESCR FROM tbLookUp WHERE FIELD = 'CRA_TYPE' AND [value] = {tbCR_AUDIT.CRA_TYPE} which would evaluatefor each record like a Formula Field which I could then just insert into the report.
    Everything I've tried in the formula editor for an SQL Expression is no good, but run just fine in the SQL Server Management Studio.
    I could just skip the "Database Expert" completly and write an SQL Expression as a "SQL Command" that would retrieve it but I'm trying to use the "Database Expert" for ease of maintenance by other people later on and keep as much as I can in CR.
    Maybe I'm asking CR for too much.
    Thanks
