clob

问题 While I try to set the value of over 4000 characters on a field that has data type CLOB , it gives me this error : ORA-01704: string literal too long. Any suggestion, which data type would be applicable for me if I have to set value of unlimited characters although for my case, it happens to be of about 15000 chars. Note : The long string that I am trying to store is encoded in ANSI. 回答1: What are you using when operate with CLOB? In all events you can do it with PL/SQL DECLARE str varchar2

问题 I have posted the similar question before but the solution to this question seems like it will be completely different, thus I hope this does not qualify for a repost. Req: I have 2 columns in a table named SETUPS with the following columns: ID INTEGER NOT NULL RPT_SCRIPT CLOB NOT NULL RPT_SCRIPT has select statements in each record. Below is a statement in the clob column WHERE ID = 1 : SELECT ID, Title, Desc, Type, LVL_CNT, TYPE_10 VALUE_10, TYPE_9 VALUE_9, TYPE_8 VALUE_8, TYPE_7 VALUE_7,

问题 I am currently trying to extract value from the clob column but always getting the result as null . I tried out many possible scenarios but for me it is always returning as null .

问题 We are running an older Oracle Server, 10.1.0.5... yes, we will upgrade soon. Some relevant NLS Settings are as follows... NLS_CHARACTERSET IS 'US7ASCII' NLS_LENGTH_SEMANTICS IS 'BYTE' Onto the question... We have well formed XML stored in CLOB columns. When trying to pull XML Element data I am using syntax like select XMLTYPE(I.CLOBFIELD).EXTRACT('/Record/RecordID/text()') as Record_ID from iTable I Where I.CLOBFIELD is the CLOB containing some XML. This works great, usually . We sometimes

问题 I would like to save a large XML string (possibly longer than 32K or 64K) into an AS400 file field. Either DDS or SQL files would be OK. Example of SQL file below. CREATE TABLE MYLIB/PRODUCT (PRODCODE DEC (5 ) NOT NULL WITH DEFAULT, PRODDESC CHAR (30 ) NOT NULL WITH DEFAULT, LONGDESC CLOB (70K ) ALLOCATE(1000) NOT NULL WITH DEFAULT) We would use RPGLE to read and write to fields. The goal is to then pull out data via ODBC connection on a client side. AS400 character fields seem to have 32K

问题 I need to display a CLOB field with longer than 4000 characters in a text field using in iReport. I am using iReport version 5.5.0, I tried converting the CLOB to InputStream but it did not work, all I get is: java.io.ByteArrayInputStream@43842a66 I tried getSubString(long,int) but it only works for strings smaller than 4000 chars. stringValue() and toString() also did not work. Thanks for any help. EDIT: Clob.getSubString(long,int) method worked fine in my latter tests, I don't know why it

问题 My question is: Is there a UTL_MATCH-like function which works with a CLOB rather than a VARCHAR2 ? My specific problem is: I'm on an Oracle database. I have a bunch of pre-written queries which interface with Domo CenterView. The queries have variables in them defined by ${variableName} . I need to rewrite these queries. I didn't write the original so instead of figuring out what a good value for the variables should be I want to run the queries with the application and get what the query

问题 I have a table with a java.sql.Clob column in Hibernate The hbm file: <class name="com.model.ClobModel" table="table1"> <id name="id" column="id"> <generator class="assigned"></generator> </id> <property name="clobData" type="clob"> <column name="ClobData"></column> </property> This is the ClobModel : private Integer id; public Integer getId() { return id; } public void setId(Integer id) { this.id = id; } private Clob clobData; public Clob getClobData() { return clobData; } public void

问题 I have a table with one column of CLOB type data, they are all very short no more than 20 bytes, however I cannot see the actual string in the CLOB data. For example if I use SELECT * , under the CLOB type every data is like: CLOB, 8 Bytes CLOB, 15 Bytes CLOB, 9 Bytes But I just want to see the content of the CLOB data. I tried: SELECT DBMS_LOB.SUBSTR(ClobColumnName, 20 ,1) And it doesn't work, error is: Error Code: 4121, SQL State: S1000 Cannot find either column "DBMS_LOB" or the user

问题 Environment: oracle 11g, spring-jdbc-3.2.2-RELEASE.jar, JDK 1.7, Oracle UCP driver. I have a stored procedure which insert record to a table with CLOB column. The SP has a CLOB input argument among other IN and OUT arguments. My Java code uses Spring StoredProcedure to call the stored procedure: public class MyClass extends StoredProcedure { public MyClass(){ ..... declareParameter(new SqlParameter("content", Types.CLOB)); ..... } public void insert(){ HashMap<String,Object> params = new
