In this example,myprocedureis used to insert just two values into a table. As the table structure gets more complicated, and you want to include error checking, the body of the stored procedure would be more complicated. But, the user's call would still just need to pas...
Summary: in this tutorial, you will learn how to call PostgreSQL stored functions using JDBC. Calling a built-in stored function example We will call a built-in string function initcap() that capitalizes the first letter of each word in a string. To call the initcap() function, you follow...
create or replace procedure p1(p_a in int, p_b in int, p_c out int) language plpgsql as $$ begin p_c := 30000; raise notice '% % %', p_a, p_b, p_c; end; $$; do $$ declare a1 int; a3 int; begin a1 := 10; call p1(a1, 20, a3); raise notice 'a3: %', a3...
PostgreSQL , CREATE PROCEDURE , CALL , 增强 , 11 背景 PostgreSQL一直以来都是通过create function来创建函数和存储过程(return void),通过select或者perform(plpgsql内部调用函数)来调用函数。 通过inline code来模拟类似procedure的用法: do language plpgsql $$ declare -- ... begin -- ... end; $$; ...
1. Creating the PostgreSQL stored procedure The example program will call the following stored procedure, which adds two complex numbers and returns the result in INOUT parameters. Let's start by creating a stored procedure: CREATE OR REPLACE PROCEDURE add_complex(IN real_1 INTEGER, IN imaginary...

CALL procedure_name '('[argument_list]')' 说明 使用CALL 语句调用存储过程。要使用 CALL 语句,您必须对 CALL 语句调用的存储过程具有 EXECUTE 特权。 参数 参数说明 procedure_name procedure_name 是(可能是 schema 限定的)存储过程名称。 argument_list argument_list 指定存储过程所需参数的列表,以逗号分隔。
CALL语句1.CALLsp_name([parameter[,...]])1.CALLsp_name[()]CALL语句调用CREATEPROCEDURE定义的存储过程。如果存储过程不带参数,调用时可以在不带括号。也就是说,CALLp()和CALLp是等价的。CALL可以使用声明为OUT或INOUT的参数将值回传给它的调用者。当过程返回时,客户端程序还可以获得例程中执行的最后一条...
