问题 Closed . This question needs to be more focused. It is not currently accepting answers. Want to improve this question? Update the question so it focuses on one problem only by editing this post. Closed last year . Please suppose that I have a package creation script stored inside a table ALPHA, in a column BETA of type CLOB. The CLOB length is > 32767 characters. Using PL/SQL code, I would like to "execute immediate" the package creation script. I could I achieve this? Thank you in advance

Unable to store CLOB data in to CLOB defined column in DB2

问题 It's a repeated issue i guess, but couldn't find a proper solution yet. Basically I am trying to insert bit huge XML i.e. 32000+ characters in to a CLOB column through DB2 procedure. Insertion is failing with the below error looks DB2 is considering the input as String rather than CLOB datatype. Can you please suggest what needs to be done?

Count CLOB Duplicates in a large Oracle Table

由 霸气de小男生 提交于 2019-12-02 10:06:48
问题 I have an Oracle database table LOG_MESSAGES with a CLOB column called MESSAGE . Some of the rows contain the same MESSAGE . For each MESSAGE which has at least a duplicate, I'd like to know the number of duplicates. Quite a number of these CLOBs are huge (> 100 kB), so converting to VARCHAR2 is out of question. Since many traditional methods such as GROUP BY do not work with CLOB , could someone please enlighten me? For information, the table is very large (around 1 TB). So an optimised

使用JDBC处理LOB大型对象

转载自 http://www.cnblogs.com/xdp-gacl/p/4009399.html 一、Oracle中大数据处理 　　在Oracle中，LOB（Large Object，大型对象）类型的字段现在用得越来越多了。因为这种类型的字段，容量大（最多能容纳4GB的数据），且一个表中可以有多个这种类型的字段，很灵活，适用于数据 量非常大的业务领域（如图象、档案等）。 　　LOB类型分为BLOB和CLOB两种：BLOB即二进制大型对象（Binary Large Object），适用于存贮非文本的字节流数据（如程序、图象、影音等）。而CLOB，即字符型大型对象（Character Large Object），则与字符集相关，适于存贮文本型的数据（如历史档案、大部头著作等）。 二、搭建测试环境 2.1、建立两个测试用的数据库表 　　建表SQL语句为： CREATE TABLE TEST_CLOB ( ID NUMBER(3), CLOBCOL CLOB) CREATE TABLE TEST_BLOB ( ID NUMBER(3), BLOBCOL BLOB) 2.2、搭建测试项目架构 　　 2.3、编写db.properties配置文件 oracleDb_Driver=oracle.jdbc.driver.OracleDriver oracleDb_Url=jdbc:oracle

DB2 query error during the retrieval of a CLOB field

From Java I am doing the following query on DB2: SELECT * FROM PRV_PRE_ACTIVATION WHERE TRANSACTION_ID = ? The field TRANSACTION_ID is a VARCHAR of length 32. I set the parameter in the preparedStatement using the setString method.

JDBC 4's java.sql.Clob.free() method and backwards compatibility

由 心不动则不痛 提交于 2019-12-01 21:32:15
I'm investigating an interesting performance issue, where there are no calls to java.sql.Clob.free() on a frequently used resource. This method on Clob was introduced in Java 6 / JDBC 4, so it might well be that this is actually a regression introduced when upgrading from JDBC 3 to JDBC 4. Is this a known issue in the Oracle JDBC driver? Can it be said that before, Clobs somehow magically freed themselves, whereas with JDBC 4, they MUST be freed manually? Or is there a driver setting that can be used to stay compatible with JDBC 3? Note, the same applies to Blob , of course. Our application

Extract specific value from CLOB (containing XML) while creating one delimited string per row of a table. CLOB value may be null on some rows

Some Context: The DB is Oracle. I am trying to create one delimited string per row of a table. Some of the values of the delimited string must come from CLOBs (containing XML). The CLOBs may be null on some rows and this is where the issue lies. For example, I have a Table: 'Item' with the following rows: 'Item_ID', 'Item_CD', 'Item_TXT' (CLOB). The table has two rows. One row has the following XML stored within 'Item_TXT', the other row's 'Item_TXT' is null. <OuterTag> <InnerTag>test</InnerTag> </OuterTag> I created the following SQL to return the first 3 elements of the delimited string:
