Move Table, index, lob/long [ZT] When you move a table to another tablespace, the index will not be moved together and will become invalid. (Lob type exceptions) Table move, which is divided:* Move a common table* Move a partition table* Long and LOB large field types move for testing and description. Index move, which is implemented through rebuildSQL> select *

Query the size of a table with a lob field in the Oracle database Note: Because the lob field has an independent lob segment for storage, for a table with a lob field, you cannot only query dba_segments. The following scripts are from: How to Compute the Size of a Table containing Outline CLOBs and BLOBs [Article ID 11

Use the in-row storage option to achieve better performance.2) use cache for frequently-read data );3) If BLOB data is often inserted or deleted rather than updated frequently by ArcSDE, set the pct_version parameter to 0, telling Oracle that data of earlier versions does not need to be maintained on the lob segment.4) The

Query the space occupied by the LOB field query the space occupied by the LOB field in the Oracle table. Each LOB field in the table is stored independently on a segment with an index segment. Therefore, you need to query two segments to obtain the total space occupied. SQL code www.2cto.com select. owner,. table_name,. column_name, B. segment_name, ROUND (B. BYT

When using oracle10g, the entity class used the Clob field, and the result was thrown disabling contextual LOB creation as Createclob () method threw error exception. The JDBC driver used is the version of OJDBC14, each version will be an error! The reason should be to provide JDBC4 support, running above JDK6;Then, you should use Ojdbc6.jar. From the official view, this is the driver of oracle11g. But there's nothing wrong with using Ojdbc6.jar to or

I tried this method myself and found that if the Blob stores text files, there will be no problem. If it is a binary file, there will be a problem in transmission.Based on your experience and reading the official Oracle documents, you can use the following methods:1. Create a record and in

the BLOB type is Empty_blob (). The previously inserted record is then queried with the Select command and locked, and then the empty object is modified to the LOB object to be inserted. 3.

We all know that previous versions of Oracle were a pain in the way of manipulating lobs in Hibernate, but the JDBC driver in its new version of oracle10g has fixed the problem. The main points of operation are as follows: 1. First, the CLOB type in the datasheet corresponds to the string type of the Java persisted class, and the BLOB type corresponds to the byte[] type. 2. When defining a hibernate label, the hibernate type of the property correspo

Previously, the LOB fields were processed using the Dbms_lob package, and a recent document found that many of the commonly used character functions support lob fields.
