To create triggers and stored procedures in PostgreSQL, you need to use SQL statements. Below are the basic steps for creating triggers and stored procedures.<\/p>\n

    \n
  1. Create a stored procedure.<\/li>\n<\/ol>\n
    CREATE<\/span> OR<\/span> REPLACE FUNCTION<\/span> my_function()\r\nRETURNS<\/span> VOID AS<\/span> $$\r\nBEGIN<\/span>\r\n   -- \u5199\u5165\u5b58\u50a8\u8fc7\u7a0b\u7684\u903b\u8f91\u4ee3\u7801<\/span>\r\n   -- \u53ef\u4ee5\u5305\u542bSQL\u8bed\u53e5\u3001\u6d41\u7a0b\u63a7\u5236\u8bed\u53e5\u7b49<\/span>\r\nEND<\/span>;\r\n$$ LANGUAGE<\/span> plpgsql;\r\n<\/code><\/pre>\n
      \n
    1. Create a trigger:<\/li>\n<\/ol>\n
      CREATE<\/span> TRIGGER<\/span> my_trigger\r\nAFTER INSERT<\/span> ON<\/span> my_table\r\nFOR<\/span> EACH<\/span> ROW<\/span>\r\nEXECUTE<\/span> FUNCTION<\/span> my_function();\r\n<\/code><\/pre>\n
      In the example above, we created a stored procedure named my_function and wrote the logic code for the stored procedure within it. Then, we created a trigger named my_trigger, which executes the my_function stored procedure when a row of data is inserted into the my_table table.<\/p>\n
      Please note that the above is just an example code. In actual applications, the logic code for stored procedures and triggers should be written based on specific requirements. When writing stored procedures and triggers, it is recommended to read the PostgreSQL official documentation for more detailed information and usage.<\/p>\n","protected":false},"excerpt":{"rendered":"
