The ORA-01084 invalid argument in OCI call error is always reported when data is inserted into the Oracle database because one of the field types in the table is CLOB and can be empty when the error is thrown when a null value is inserted into the field. Later, if you decide whether to use DBNull.Value for null values, this resolves the problem.Null refers to an invalid object reference, whereas DBNull is a class, and DBNull.Value is its only instance

The ODAC component supports the BLOB and CLOB data types of Oracle 8. You can use the Toraquery component to get the value of the LOB field, and you can also get a long or long ROW field using the same method. When you need to use SQL DML and PL/SQL statements to access these fields, you will find that the use of LOB data types is significantly different. Blob and CLOB data types are stored in table column

Today, I encountered A problem. In database A and database B, the table structure is the same. to export some records to table A of database B,The problem is that two identical tables in the two databases contain BLOB and CLOB fields. After thinking about it, I found a method for the moment,Of course, I do not know whether there are any better tools, that is, using the exp and IMP of oracle itself, the method is: 1 exp XXX/XXX @ XXXX tables = (xxxx)

During full-text ORACLE search, the updated fields cannot be retrieved. Prerequisites: 1. This field is of the CLOB type. 2. the keyword used for retrieval is CONTAINS. The SQL statement is as follows: Select * from tableAwhereCONTAINS (globle, 'China '); * Note: if the search field contains '-' data, add '\' to it '\' Select * from tableAwhereCONTAINS (globle, 'China-Beijing '); After updating the value of the globle field, you can

1. First, we will introduce the corresponding configurations of hibernate. For database fields, how do we define HBM. xml and pojo of hibernate, corresponding to blob and clob? We define HBM. XML as follows: Blob à org. springframework. Orm. hibernate3.support. blobbytearraytypeClob à org. springframework. Orm. hibernate3.support. clobstringtype Using the corresponding method above, the corresponding type in pojo is BlobIt is define

I use dblink to access a remote database table to read data, The ORA-22922 error is reported when there is a clob field in the database table, Check on the network to find a solution. The description is as follows: 1. Use create global temporary table tb_tmp to create a local Table with the same structure as the remote database table. 2. Use insert into tb_tmp select * from TB @ remote database connection. This allows you to import data from a

When processing the clob character field, if the string is directly passed to oracleparameter, an exception occurs when the string length exceeds 4000: ORA-01460: conversion requests cannot be implemented or unreasonable Because the maximum length of Oracle characters is 4000, You need to construct an oracleclob object and write the string to be passed into oracleclob. The following code is used: Command. commandtext = "select * from table (analyse

Inserting a piece of article (1000~2000) into the CLOB attribute of a database in a project today will report an error with a string that is too long.

Issue background: Recently, the company database server is centralized to one machine (252) for the unified management of the databases distributed on each server. For the difference in the last section of the IP address as the name of each machine. One of the decentralized servers is 98. One of the database is relatively small, with exp export, with IMP import is an error, there are clob field table (for example: T_news) has failed to import. I do no
