I. Differences in the types of BLOBs and CLOB in OracleBLOBs and Clob are large field types, blobs are stored as binary, and CLOB can store text directly. The two are interchangeable, or you can use LOB fields directly instead of the two. But in order to better manage the Oracle database, usually like pictures, files, music and other information in the Blob field

In oracle, if a column type is varchar2, it cannot be directly converted to the clob type. It can be modified indirectly. The following is an experiment: In oracle, if a column type is varchar2, it cannot be directly converted to the clob type. It can be modified indirectly.

JDBC 2.0 provides new data types introduced in the sql3 standard, such as blob (Binary Large Object), clob (character large object), array object, ref (Object reference, supports object reference and UDT (user-defined data type, user-defined datatype. These new data types are combined to allow database designers to create richer modes and simplify the processing and persistence of complex data. For example, to insert a user's photo into the tbl_user

This article illustrates the method of PHP handling Oracle's CLOB. Share to everyone for your reference. The specific methods are as follows: 1. Write DataWhen using the preprocessing method of PDO, if you use Bindparam () without specifying the data type of the field or using Execute (), PDO defaults to string type and limits a default length So you must use Bindparam () or Bindvalue () when you save the Clob
