4.3 How do I匬ut comments on a table and its columns?</font></b><P><B>Problem</B><p>With the large number of tables used in our applications and the number of developers working in our organization, it is important that we document tables and their columns contained in the database. How do I put comments on tables and their columns?<p><B>Technique</B><p>The COMMENT statement is used to create comments on tables and columns. The comments are stored in the data dictionary and can be queried through the ALL_TAB_COMMENTS and ALL_COL_COMMENTS data dictionary views. <A HREF="image/04oht04.gif" TARGET="_blank">Figure 4.4</A> shows the syntax of the COMMENT statement.<p>If the user account connected to the database is not the owner of the table, the user account must have the COMMENT ANY TABLE system privilege in order to put a comment on the table.<p><B>Steps</B><p><B>1.</B> Run SQL*Plus and connect to the WAITE user account. CHP4_4.SQL, shown in <A HREF="image/04oht05.gif" TARGET="_blank">Figure 4.5</A>, creates a sample table that is used throughout this How-To.<p>Run the file to create the sample table.<p><code><b>SQL> START CHP4_4.sql<p>Table created.</b></code><p>2. Load CHP4_5.SQL into the SQL buffer. The file contains a statement to put a comment on the DEPT4 table created in the previous step.<p><code><b>SQL> GET CHP4_5.sql<p>1 COMMENT ON TABLE DEPT04 IS 2* 慏epartments in the Organization.⌨️ 快捷键说明
