If we want to save the case to the data warehouse, we can use clob and blob in JDBC to separate the text and binary statements for further saving, in spring, clob and blob can be handled through jdbctemplate. For example, the table for setting up your MySQL data is as follows: 12345 CREATE TABLE test ( id INT AUTO_INCREMENT PRIMARY, txt TEXT, image

now.The LOB type can be BLOB or CLOB: BLOB is a Binary Large Object. It is suitable for storing non-text byte stream data (such as programs, images, audio and video ). CLOB, a Character-Type Large Object (Character Large Object), is related to Character sets and is suitable for storing text-type data (such as historical files and big part-head books ).The follow

1. Read and write LOBIn addition to numbers, strings, and dates, many databases can store large objects, samples, or other data. In SQL, a binary large object is called a blob, and a large object of characters is called a clob.To read the LOB, the SELECT statement needs to be executed, and then the GetBlob or Getclob method is raised on resultset, so that objects of the

Expert analysis: correctly export LOB data in DB2 For example, there is a table (USER_INFO) for employee information. This table contains three fields: employee ID, employee name, and employee ID card copy. Because the size of the employee ID card copy is relatively large, the LOB data type is used in the database. When you need to export the data in this table to a specific file, as long as the size of co

Everyone knows that the previous version of Oracle operating lob in Hibernate is quite painful, but the JDBC driver in its new version of Oracle10g has fixed this problem. The operation points are as follows: 1. First, the clob type in the data table corresponds to the string type of the Java persistence class, And the Blob type corresponds to the byte [] type. 2. When defining the hibernate tag, the hi

Today, we have a function that requires operations on the clob field. If you encounter several problems during this period, you can solve them. Remember to avoid repeating the same mistakes in the future.
