How to create longtext or blob data types in SQL using labview

Hello,
I am fairly new to SQL, and I'm using the labview database connectivity toolset.  Using labview 6.1
I am using the DB Tools Create Table vi to create my tables.  I want the tables to hold 1000 character strings.  But the longest string that I can insert seem to be 255 characters.  I think It is a limitation of the "String" data type in SQL so I need to use text or blob types.  The problem is I created a control for the "Column Information" field and I see the following selections for the data type. (String, Long, Single, Double, date/time, binary).  I dont see any selection for text or blobs.  How do I define another data type that is not part of the selection in the control?
Thanks for any help.

I don't know about defining long text, but the equivalent of a BLOB should be the binary data type, which just holds the data you put into it without formatting it.
Try to take over the world!

  • How to create an item with date type mm/yyyy (no day)

    Hello,
    Is it possible to create an item with date type mm/yyyy (no day)? I want the pop-up date picker to just show month and year.
    Thanks,
    Jen

    Hi,
    you cannot pop-up date picker to just show month and year, but you can set your item format as MM-YYYY
    You can check this APEX_ITEM.DATE_POPUP2 at : http://docs.oracle.com/cd/E23903_01/doc/doc.41/e21676/apex_item.htm#CHDJHBCG (if using apex 4.1) else http://docs.oracle.com/cd/E10513_01/doc/apirefs.310/e12855/apex_item.htm#CHDFDDEI

  • Using a BLOB data type in a CMP Entity Bean: Error when send large files

    I've successfully impleenting BLOB in my EJB. But the main prob is, it can only work on small file which is around 3K. Any larger files than that will caused error (refer below). I got info from a friend which is using normal JDBC call to insert a file into BLOB column that you can't use java.sql.Blob data type which will have this limitation. He suggested that by using oracle.sql.BLOB, this prob won't exist.
    The problem is I'm unable to use oracle.sql.BLOB in my CMP EJB because in the jbosscmp-jdbc.xml, I'm able to specify the normal BLOB only which is java.sql.Blob (Refer below).
             <cmp-field>
                <field-name>attachment</field-name>
                <column-name>attch</column-name>
                <jdbc-type>BLOB</jdbc-type>
                <sql-type>BLOB</sql-type>
            </cmp-field>So, how do I solve this problem? I need to store files which the size is much bigger than that. I'm using JBoss 4 as my app server and Oracle 9i as my DB. I can see that there's many ppl facing this prob, but no solution to it. Pls advise. Thanks.

  • How to set default value to date type attribute.

    Hi,
    How to set default value to date type attribute.
    E.g I want to set u201C01/01/1999u201D to date attributes.
    First i want to set value and then i want to fetch the same & want to check equals.
    please suggest solution.
    Regards,
    Smita

    Hi,
    In wdinit() method u can set the date
    DateFormat df = new SimpleDateFormat("MM/dd/yyyy");
    Date today = Calendar.getInstance().getTime();
    String reportDate = df.format(today);
    wdContext.currentContextElement().setFromDate(reportDate);
    Another way you have set the this formate like that
    1. Create a Simple type under "Dictionaries->SimpleType" called DateFormat
    2. Select the type as "date"
    3. Go to the "Representation" tab and set the format as "dd/MM/yyyy" (or whatever u want, but month should be MM)
    4.Bind the context attribute to the type created now.
    Hope this helps u.
    Best Regards

  • JDBC/RMI driver does not support BLOB data type

    WLS 5.1 JDBC/RMI driver does not support BLOB data type. It is said in the Weblogic e-doc.
    I am using DataSource for database connections, meaning JDBC/RMI driver is actually producing
    database connections. I need several columns of BLOB types in my Oracle tables.
    Should I use the "JTS" driver instead in order to have the BLOB types supported ?
    Thanks for help.
    [att1.html]

    The error java.rmi.UnmarshalException seems to indicate you are somehow accessing the data-source over RMI, this seems odd. Are you running TopLink on a client and trying to connect to a WebLogic DataSource on the server?
    Maybe try connecting directly to the DataSource without going through TopLink and see if you encounter the same issue.
    You could also look at the TopLink WebLogic Examples and see how their configuration is different than your own.

  • BLOB Data Type

    Hi
    I have stored some images in my table using blob data type. Can anyone plz tell me how to fetch those images using oracle forms.
    Thanks.

    once you base you DataBlock in forms on this table with BLOB column you will automatically get an image item in the forms for this column.
    rest is same as usual, when you do an execute query you should get the records.
    but the images you have stored in the database should be as one of the following types.
    BMP, CALS, GIF, JFIF, PICT, RAS, TIFF, TPIC.
    set the appropriate value in the property of the Image item for the "Image Format" property.

  • How to create tables for control data

    HI
    How to create  tables for controls of types of data (screen control)? what is the process for this
    Regards,
    Anil

    Well, do you want to do it the easy way?  If so, then just create a table maintenance program.  You can do this via SE11, utilites, table maintenance generator. The table maintenance will be generated and you can then maintain the table via SM30. 
    If you want to go the more challenging way, you can write your own table maintenance program using a table control on your screen.  You can use the table control wizard to help you along.

  • How to create an extension for generated type idoc

    Hi all,
    Can u please look into this
    How to create an extension for generated type idoc ?  for example Idoc type BATMAS02

    Enter transaction WE30 (ALE->Extension-> IDOC types->Maintain Idoc type)
    - Type in your name of the extended IDOC type (usually starting with 'Z') and click on the Basic IDoc type, click the create icon.
    - Click on Create new and enter a description and press enter.
    - Click on ZIDOCTYPE01 and then on the Create icon.
    - Enter ZIDOCTYPE as the segment type, click on Segment Editor.
    - Enter a description for your segment type and create.
    - Enter a description for your segment, enter each field required in your IDoc and press enter to validate.
    - Save and generate, press back
    - To release the segment choose Goto, Release from the menu.
    - Check the box on the line of your segment.
    - Save, back and enter.
    - Your Idoc type structure should be displayed with your new segment.
    - Save and back.
    - To release the Idoc type choose Extras, Release type from the menu and Yes.
    ALE FUNCTION MODULE ENHANCEMENTS
    Having extended the IDOC type to contain additional fields for an inbound or outbound application, you now want to enhance ALE function modules for populating the additional segment on the outbound or applying the additional segment data on the inbound application.
    The core working code for ALE processes for a given application area is always encapsulated in ABAP/4 function modules. These function modules are associated with such control information as message types and process codes. So the ALE process checks this control information and derives the name of the function module to invoke for that particular IDOC processing from certain database tables. These function modules contain objects known as customer functions, which can be considered SAP Enhanced user exits. A function module is called at a particular point during the processing of the main program or function module, and it can be used to influence data processing at that point by adding code to the customer function. The customer function behaves like a normal function module and has import and export parameters, tables (internal tables) statement, and exception processing. Unlike a conventional user exit, customer functions give you the ability to modify only data available to you by the function moduleâs parameters and internal tables. While most ALE/EDI function modules are supported by customer functions, there are ALE/EDI processes that still use conventional user exits. There are a few ways to determine which function module to enhance for a given message type/process code:
    • For master data distribution, from SALE go to Extensions -> Master data distribution -> Setup additional data for message types. Search for message type DEBMAS in this example. You see an entry for DEBMAS associated with function module MASTERIDOC_CREATE_SMD_DEBMAS. This data is stored on table TBDME. The function module names for all master data message types follow this pattern: MASTERIDOC_CREATE_SMD_messagetype. This function module calls another function module of name MASTERIDOC_CREATE_DEBMAS or MASTERIDOC_CREATE_messagetype. Search for the words customer function, and you find several hits that can be used to add code to the function module.
    • From WEDI got to Control -> Inbound process codes -> Inbound with ALE service -> Processing by function module (transaction WE42), or from WEDI go to Control -> Outbound process codes -> Outbound with ALE service -> With function module (transaction WE41). There will be function modules associated with the process codes. For inbound, the function modules usually follow this pattern: IDOC_INPUT_messagetype: for example, IDOC_INPUT_CHRMAS for inbound characteristics master.
    • Use transaction WE57 or from WEDI go to Development -> Message/Application Object. The entries list the function module, Business Object, message type, and IDOC type that are used for inbound ALE/EDI interfaces.
    Customer functions are not specific only to ALE and EDI but also to all programs/modules in SAP R/3. Customer function is a SAP enhancement component; the other two types are menu and screen enhancements.
    All customer function exits are maintained in SAP enhancements and are found by using transaction SMOD. After executing transaction SMOD, pull down (F4) on the enhancement name field, and execute again. This provides you with a list of all SAP enhancements available. SAP enhancements are grouped by development class pertaining to an application area. Choose Application development R/3 SD master data distribution for development class VSV to lead to a screen that lists VSV00001 as an enhancement (see Figure 5). Press Component +/- to display its function exit components. There are four possible components listed, all of which are function exits (and are function modules) that are called from the ALE function modules in the form Call Customer Function Î001â. This is a special occurrence of the ABAP statement Call. Go to item Exit_SAPLVV01_ 001, which you need to enhance for the Customer Master outbound example of an IDOC extension. In the ALE-function module MASTERIDOC_CREATE_DEBMAS, the statement CALL Customer Function 001 is translated in the background to call component EXIT_SAPLVV01_001. Although this function exit can be edited using transaction SE37, you will use a simpler approach.
    When you use SAP enhancements and their components, you manage them with an SAP object known as a project, which is like an envelope containing the selected enhancements and their components. A project can be used to control the execution of components and to transport them to other clients and instances in SAP. Basically, the process involves creating a project, including enhancements and components that are to be enhanced, editing the components, and then activating the project. The following process creates a project for our example Customer Master IDOC extension:
    • Execute transaction CMOD.
    • Enter name of project, say CSTMAST1.
    • Click on Create.
    • Enter a description of the project.
    • Save.
    • Click on SAP Enhancements.
    • Enter VSV00001 for Enhancement.
    • Save.
    Once youâve created the project, edit the function exit components and activate the project. Remember that the code in the function exit enhancement will execute only if the project is activated. In fact, this is a convenient SAP enhancements feature, whereby the work in progress (developing code in the customer function) will not affect users of that application. When the code is completed, the project can be activated so the enhanced functionality takes effect. It can also be deactivated for maintenance.
    As mentioned earlier, customer functions (function exits) are embedded in ALE function modules and can be used to influence the creation and modification of IDOC data on an outbound application or to post additional or modified IDOC data to an inbound R/3 application. Function exits are similar to regular function modules, with import/export parameters, tables (internal tables), and exceptions.
    The two important factors to consider while developing the customer function are:
    1. The point in the ALE function module where the function exit occurs
    2. The data made available by the customer function that can be modified or posted to the R/3 application, based on the direction.
    Because some function modules have several customer functions, it is critical to choose the function exit best suited for that particular enhancement. Do not attempt to perform activities that the function exit is not designed for. The importance of this point is illustrated by the following description of enhancing function modules for outbound and inbound ALE interfaces.
    Outbound interfaces. In an outbound ALE interface you use function exits (customer functions) to populate additional segments created by an IDOC extension or to modify the existing IDOC data segments as per business requirements. Previously, you identified that enhancement VSV00001 has a component EXIT_SAPLVV01_001 (function exit), which can be used for populating the additional data segment Z1SADRX that you created in the IDOC extension ZDEBMASX (IDOC type ZDEBMASZ, based on Basic IDOC type DEBMAS02). You also learned that the ALE function module that calls this function exit is MASTERIDOC_CREATE_DEBMAS, which has a statement Call Customer Function 001.
    Browse the function module MASTERIDOC_CREATE_DEBMAS using transaction SE37. You will find that this customer function is invoked for every segment of IDOC type DEBMAS02. In fact, the function exit is called soon after the creation of an existing segment has been populated with data and appended to the IDOC data table (internal table). Also, the function exit is exporting the message type, IDOC type, and the segment name and is importing the IDOC extension type. It is also passing the IDOC data internal table. This indicates that the ALE function module is allowing you to populate additional segments for every existing segment and modify the existing segmentâs data.
    Letâs write ABAP/4 code to accomplish the task of populating IDOC segment Z1SADRX with a contact personâs business address:
    • From SE37, display function module MASTERIDOC_CREATE_ DEBMAS.
    • Find Customer Function 001.
    • Double-click on 001.
    • The function EXIT_SAPLVV01_001 will be displayed.
    • Double-click on INCLUDE ZXVSVU01.
    • You will be asked to create a new include object. Proceed as desired.
    • Enter code (as in Listing 1).
    • Be sure to perform a main program check (Function Module -> Check -> main program) and extended program check (Function module -> Check -> Extended check).
    Now that you have extended the IDOC and enhanced the ALE function module based on the requirements for the contact personâs business address on the Customer Master, letâs test the interface. You should create a logical system and define a port for this interface. You should also configure the Customer Distribution Model to indicate that message type DEBMAS is being distributed to this logical system. The only difference in configuration between a regular outbound ALE interface and an enhanced one is the partner profile definition. While maintaining the outbound parameters of the partner profile, make sure the IDOC type is ZDEBMASZ. The fields for Basic IDOC type and extension type are automatically populated with DEBMAS02 and ZDEBMASX, respectively.
    To maintain the contact personâs business address of a customer:
    • Use transaction BD12 or from BALE go to Master Data ->Customer -> Send and send that Customer Master record by executing the transaction after filling in the relevant fields such as customer number, message type, and logical system.
    • Use transaction WE02 or WE05 to verify the IDOC created. You should see the new segment Z1SADRX populated with the correct data.
    With SAP releases below 4.5B, you cannot capture changes to business address through change pointers because a change document object is not available for capturing business address changes, and also earlier releases have not been configured to write change documents for a contact personâs business address. If you would like this functionality, you can either create change document objects, generate function modules to create change documents, and perform ALE configuration to tie it in, or make a cosmetic change to the contact person screen data while changing the contact personâs business address so that it gets captured as a change to the Customer Master. Subsequently, the ALE enhancement that you performed captures the contact personâs business address.
    Inbound interfaces. The process for enhancing inbound ALE interfaces is similar for outbound, with a few exceptions; specifically in the coding of customer functions (function exits) for the ALE/EDI function modules.
    The first step is to create an IDOC extension for the specific Basic IDOC type by adding new segments at the appropriate hierarchy level: that is, associated to the relevant existing segment. Populate the data fields on the new segments with application data by the translator or external system/program before importing them into the R/3 System. Then, find the ALE function module that is invoked by the inbound processing. By browsing through the code or reading the documentation on the function exit enhancements using the SMOD transaction, identify the function exit in which you should place your code. The technique used in the code to post the additional or modified IDOC data to the application can vary based on the application rules and requirements, the data available at that point in processing, and the application function modules available to update the application tables. It is important to search first for application modules that process the data and see if they can be called within the function exit. If the additional data in the extended segments in specific to a custom table or resides in nonkey fields of a single or small set of tables, you may be able to update it directly by SQL statements in the function exit. This approach should be carefully evaluated and is certainly not highly recommended.
    Another option is to use Call Transaction from within the function exit to process the additional data. For example, in the case of message type WMMBXY for inbound goods movements from a warehouse management system, the standard interface creates batches for materials, but does not update its characteristics. In such a case, you can use Call Transaction MSC1 to create the batch and assign characteristic values to it from within the function exit provided.

  • How to create a variance on data that exists iIn only one database column

    How to create a variance on data that exists iIn only one database column?
    I'm trying to create a calculation to show the difference between the budgets for two different years in a Discoverer crosstab query.
    I'm using the lag function to repeat the value of a column for the current year and the year before.

    Lag and lead seems to be the only choice and they work excellent. Checkout the new 10g Database features. There is new SQL modal clause which might give additional and powerful analytics but in this case lag and lead should be sufficient.

  • How to Get Default Value of a Data Type in SQL Query.

    Hi all,
    I am creating a procedure which will take input the table name and Column Name.
    In the Output i would like to have the data type and default value of that data type which will be used by a another procedure to blank the selected column in the database.
    I tried with SET NULL on the column but as the database is of navision the table have property set to NOT NULL.
    Here is what i have done till now.
    Create Procedure Get_Column_type
    @parm_table_name nvarchar(200),
    @parm_column_name nvarchar(20),
    @parm_result nvarchar(20)OUTPUT
    AS
    BEGIN 
    select @parm_result =
    DATA_TYPE from INFORMATION_SCHEMA.COLUMNS IC
    where TABLE_NAME = '[' + @parm_table_name +']' and COLUMN_NAME = '[' + @parm_column_name + ']'
    END
    GO
    Now instead on write a case statement for so many data types in SQL, i was thinking is it possible someway that above procedure also returns the default value which i can set in another procedure.
    Let me know if its possible or not? Thanks in advance.

    Do you looking for something like this?
    create table t10 ( c int default 1)
    SELECT so.name AS table_name, 
              sc.name AS column_name, 
              sm.text AS default_value
         FROM sys.sysobjects so
         JOIN sys.syscolumns sc ON sc.id = so.id
    LEFT JOIN sys.syscomments SM ON sm.id = sc.cdefault
        WHERE so.xtype = 'U' 
          AND SO.name = 't10'
     ORDER BY so.[name], sc.colid
