Oracle How to check the table space to which a table belongs

Oracle database is a powerful relational database management system. Table space is used to manage data in Oracle database. Important concepts of storage space. In Oracle, each table needs to be stored in a specific table space. By viewing the table space to which the table belongs, it can help the database administrator better manage the storage structure of the database. The following will introduce how to view the table space to which a table belongs in the Oracle database and provide specific code examples.

In the Oracle database, you can view the table space to which the table belongs through the system view DBA_TABLES. The DBA_TABLES view stores information about all tables in the database, including table names, owners, table spaces, etc. You can query this view to obtain table space information for a table.

The following are the specific steps and code examples to view the table space to which the table belongs:

Step 1: Log in to the Oracle database as a system administrator

In SQL*Plus or other databases In the client tool, use the system administrator account (such as SYS user) to log in to the Oracle database.

Step 2: Execute the SQL query statement to view the table space to which the table belongs

Execute the following SQL query statement to view the table space information of the specified table through the DBA_TABLES view:

SELECT table_name, tablespace_name 
FROM dba_tables 
WHERE owner = '表拥有者' 
AND table_name = '表名称';

In In the above code example, you need to replace "table owner" and "table name" with the owner and table name of the table you want to view. After executing the above SQL statement, the query results will be returned, in which the "tablespace_name" column is the name of the table space to which the table belongs.

For example, if you want to view the table space to which the table named "EMPLOYEE" belongs, you can execute the following query statement:

SELECT table_name, tablespace_name 
FROM dba_tables 
WHERE owner = 'HR' 
AND table_name = 'EMPLOYEE';

Through the above steps and code examples, you can easily view the Oracle database The table space information of the tables in the database helps database administrators better manage the storage structure of the database.

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
