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!

Using oracle.sql.BLOB data type in Java Class to pass in a Blob

All,
I'm trying to pass in a BLOB from PL/SQL to a Java Class, but the BLOB isn't passed correctly.
When I check the length of the BLOB in PL/SQL its different from the length of the BLOB in java.
I'm using DB 11g and the ojdbc5.jar file in my java classes.
The java function uses the oracle.sql.BLOB type to get the parameter.
The java class is loaded into the DB and called via a PL/SQL function.
Kind regards,
Nathalie

The question is indeed a little ambigious defined ;o)
When I pass the BLOB to the java method and invoke BLOB.getBytes() and then get the length of the BLOB in java the length of the BLOB is bigger than in PL/SQL.
When I use the method 'getBinaryStream' and write this to a buffer, the code works.
I will log a tar regarding the getBytes()-method to ask for more detailed information regarding the methods provided using the JDBC Drivers.
Kind regards,
Nathalie

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 migrate SQL Server image data type to Oracle 8 BLOB data type?

Hi,
I have to migrate data from sql server to Oracle 10 g.
I am unable to migrate image data type from sql server to blob data type in oracle.
Iam using Oracle Heterogenous Services to migrate the data,Using Merge statement and database link.
I am getting the following error-
ERROR at line 7:
ORA-00932: inconsistent datatypes: expected BLOB got LONG BINARY
Can any one suggest me how to migrate Image datatype to BLOB???

Hi you might want to post your question in General Forum.

How we handle CLOB and BLOB Datatypes in HANA DB

Dear HANA Gurus,
We have would like to build EDW using HANA base on our source system Oracle and it's supports CLOB and BLOB datatypes
Would you please suggest how do we handle in HANA DB.
Let not say it's oracle specific.
Regards,
Manoj

Hello,
check SAP HANA SQL Reference Guide for list of data types:
(page 14 - Classification of Data Types)
https://service.sap.com/~sapidb/011000358700000604922011
For this purpose might be useful following data types:
Large Object (LOB) Types
LOB (large objects) data types, CLOB, NCLOB and BLOB, are used to store a large amount of data such as text documents and images. The maximum size of an LOB is 2 GB.
BLOB
The BLOB data type is used to store large binary data.
CLOB
The CLOB data type is used to store large ASCII character data.
NCLOB
The NCLOB data type is used to store a large Unicode character object.

How to convert CLOB to BLOB with SQL Developer migration wizard?

Hi,
According to our requirement, we need to only migrate data from SQL Server 2008 to Oracle 11. I use the SQL Developer 3.0.04 migration wizard to do it.
I do migration from SQL Server (database name: SCDS41P2) to Oracle (User name: HCDS41P2).
My migration steps are as below: (I need to modify the target schema, so I add the steps 2) and step 3) )
1) Do migration by SQL Developer migration wizard;
2) Remove the Converted Database Objects node from migration project;
3) Re-do convert by SQL Developer migration wizard (contains changing the target schema);
When do step 1), the DBO_SCDS41P2 user is created automatically. CLOBTOBLOB_SQLDEVELOPER procedure is also created in this user.
I continued to run step 2) and step 3) with online mode. And find the table data which contains BLOB column can be moved into the target table. But from the Logging Page, I can't see the other detailed error info, so that I can't check which tables don't move data successfully.
Could you please tell me where the detail log file (e.g. contains every table's migration status) is if I use the online mode?
Additional, If I use offline mode to do step 3), I found the CLOB data can't be converted into BLOB automatically. Because in the load script (that is oracle_ctl.bat), only copy the source data to the CLOB column. After copy, it don't deal with the converting from CLOB to BLOB.
So could you please tell me how to convert CLOB to BLOB with offline mode?
Thanks so much.

Hi,
For your first question about logging - after the migration there will be an entry in the right hand panel for the migration project. If you open this there are various fields that give information about the status of each part of the migration. Does this give you the information you need ?
For the second problem about offline moving blob data have a look at the SQL*Developer documentation -
Oracle® SQL Developer User’s Guide Release 3.0
in the section -
2.2.8.1.4 Populating the Destination Database Using the Data Files
which describes the problem and how to get round it.
Regards,
Mike

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.

New Effective CAL essay: How do I create an abstract data type in CAL?

How do I create an abstract data type in CAL? An abstract data type is one whose internal representation can be changed without needing to modify the source code of client modules that make use of that type. For software maintainability, it is a good idea to make a type that is subject to change or enhancement into an abstract data type. Another reason to create an abstract data type is to enforce invariants for values of the type that can only be ensured by using constructor functions (i.e. functions that return values of that type). In principle it is simple to create an abstract data type in CAL. For an algebraic data type, make the type constructor public and all data constructors private. For a foreign data type, make the type constructor public and the implementation scope private. If a scope qualifier is omitted, the scope is taken to be private. For example, the Map algebraic data type has the public type constructor Map and the data constructors Tip and Bin are each private, so it is an abstract data type. /** A map from keys (of type {@code k@}) to values (of type {@code a@}). */ data public Map k a = private Tip | private Bin size :: !Int key :: !k value :: a leftMap :: !(Map k a) rightMap :: !(Map k a); There are a number of invariants of this type: the size field represents the number of elements in the map represented by its Bin value. The keys in leftMap are all less than key, which in turn is less than all the keys in rightMap. In particular, non-empty Map values can only be created if the key parameter type is a member of the Ord type class. Values of the Map type can be created outside the Cal.Collections.Map module only by using constructor functions such as insert: insert :: Ord k => k -> a -> Map k a -> Map k a; public insert !key value !map = ... The owner of the Cal.Collections.Map module must ensure that all invariants of the Map type are satisfied, but if this is done, then it will automatically hold for clients using this function. Some examples of foreign abstract data types are Color, StringNoCase and RelativeDate: data foreign unsafe import jvm private "java.awt.Color" public Color; data foreign unsafe import jvm private "java.lang.String" public StringNoCase; data foreign unsafe import jvm private "int" public RelativeDate; The private implementation scope for Color means that a foreign function whose type involves Color can only be declared in the Cal.Graphics.Color module where the Color type is defined. A foreign function declaration involving the Color type relies on the compiler knowing that the Color type corresponds to java.awt.Color to resolve the corresponding Java entity i.e. it must know about the implementation of the Color type. Having a private implementation scope means that the Color type can be changed to correspond to a different Java class, or indeed to be an algebraic type, without the risk of breaking client code. In all these three cases there are useful, and different, design reasons to adopt a private implementation scope: For RelativeDate, the Java implementation type int represents a coded Gregorian date value in the date scheme used by Crystal Reports. Not all int values correspond to valid dates, and the algorithm to map an int to a year/month/day equivalent is fairly complicated, taking into account things like Gregorian calendar reform. Thus, it is desirable to hide the implementation of this type. For StringNoCase, the implementation is more straightforward as a java.lang.String. The reason to adopt a private implementation scope is to ensure that all functions involving StringNoCase preserve the semantics of StringNoCase as representing a case-insensitive string value. Otherwise it is very easy for clients to declare a function such as: foreign unsafe import jvm "method replace" replaceChar :: StringNoCase -> Char -> Char -> StringNoCase; which does not handle case-insensitivity correctly, but is a perfectly valid declaration. This declaration results in a compilation error when it is placed outside the module in which StringNoCase is defined because of the private implementation scope of StringNoCase. For Color, the issue is somewhat more subtle. The java.awt.Color implementation type is semantically the same as the CAL Color type. The problem is that java.awt.Color is mutable (since it can be sub-classed to create a mutable type). It is preferable for a first-class CAL type to not be mutable, so we simply make the implementation scope private to ensure that this will be the case. A somewhat less encapsulated kind of abstract data type can be created using friend modules and protected scope. For example, if an algebraic type is public, and all its data constructors are protected, then the data constructors can be accessed in the friend modules of the module in which the type is defined. Effectively this means that the implementation of the semantics of the type stretches over the module in which the type is defined, and all of its friend modules. These must all be checked if the implementation of the type is modified. Given the merits of abstract data types discussed above, it is perhaps surprising that most of the core types defined in the Prelude module are not abstract data types. For example: Boolean, Char, Int, Double, String, List, Maybe, Either, Ordering, JObject, JList, and all record and tuple types are non-abstract types. There are different reasons for this, depending on the particular type involved. For example, Boolean, List, Maybe, Either and Ordering are all rather canonical algebraic data types with a long history in functional languages, with many standard functions using them. They are thus guaranteed never to change. In addition, their values have no particular design invariants that need to be enforced via constructor functions. Exposing the data constructors gives clients some additional syntactic flexibility in using values of the type. For example, they can pattern match on the values using case expressions or let patterns. Essentially the same explanation holds for record and tuple types. Although non-tuple record types are less canonical, they do correspond to the fundamental notion of an anonymous named-field product type. The "anonymous" here simply means that the programmer can create an entirely new record type simply by creating a value; the type does not have to be declared anywhere prior to use. Char, Int, Double, String, JObject and JList are foreign types where in fact part of the semantics of the type is that we want clients to know that the type is a foreign type. For example, we want clients to know that Prelude.Int is essentially the Java primitive unboxed int type, and has all the semantics you would expect of the Java int type i.e. this is quite different from RelativeDate which is using int as its implementation type in a very tactical way that we may choose to change. One can think of a public foreign type declaration with public implementation scope as simply introducing the Java type into the CAL namespace. One interesting point here is with CAL's naming convention for public foreign types. We prefix a type name by "J" (for "Java") for foreign types with public implementation type such that the underlying Java type is mutable. This is intended as mnemonic that the type is not a pure functional type and thus some caution needs to be taken when using it. For example, Prelude.JObject has public Java implementation type java.lang.Object. In the case where the underlying Java type is not mutable, we do not use the prefix, since even though the type is foreign; it is basically a first class functional type and can be freely used without concern. For example, Prelude.String has public Java implementation type java.lang.String. In the case where the implementation type is private, then the fact that the type is a foreign type, whether mutable or not, is an implementation detail and we do not hint at that detail via the name. Thus Color.Color has as its private Java implementation type the mutable Java type java.awt.Color. When creating abstract data types it is important to not inadvertently supply public API functions that conflict with the desired public semantics of the type. For example, if the type is publicly a pure-functional (i.e. immutable) type such as Color, it is important not to expose functions that mutate the internal Java representation. A more subtle case of inadvertently exposing the implementation of a type can occur with derived instances. For example, deriving the Prelude.Outputable and Prelude.Inputable type classes on a foreign type, whose implementation type is a mutable Java reference type, allows the client to gain access to the underlying Java value and mutate it
(by calling Prelude.output, mutating, and then calling Prelude.input). The solution in this case is to not derive Inputable and Outputable instances, but rather to define a custom Inputable and Outputable instance that copies the underlying values.

Hi Pandra801,
When you create a the external content type, please try to add a filter based on your select statement.

Or, try to create a stored procedure based on your select statement, then create ECT using the SQL stored procedure.

BLOB data type. Will it be available in BO XIR4?

Hi,
Does any know if we will be able to use BLOB data type in the new coming release of BO?
Currently the only way you can use images is copying your image files physically to a folder because BO doesn't recognize BLOB data type from the database. Is there another way around this? Please share it!
Thanks,
Katia.

i dont think BO will support BLOB data
