First, create a new module in the project directory called call_function.py: Second, define a new function called get_parts() that calls the get_parts_by_vendors() function in PostgreSQL: import psycopg2 from config import load_config def get_parts(vendor_id): """ Get parts provided by ...
调用expand_function_arguments补充CallStmt->FuncExpr->args,加入指向参数和默认参数。 自己拼接List outargs记录输出参数 【2】CallStmt是如何使用的 (《Postgresql源码(79)plpgsql中多层调用时参数传递关键点分析(pl参数)》问题四:内层ExecuteCallStmt如何构造fcinfo->args?) 第一步:ExecuteCallStmt时遍历CallStmt->Fu...
Third, execute the function call and obtain the result. The following example creates a new class named Util and defines a static method properCase() that calls the initcap() function in PostgreSQL: import java.sql.SQLException; import java.sql.Types; public class Util { public static String ...
1. 走FunctionCallInvoke进入plpgsql_exec_functions开始执行被调用函数。实验用例 代码语言:javascript 代码运行次数:0 运行 AI代码解释 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...
使用php连接PostgreSQL,报错Call to undefined function pg_connect(); 跟换成pdo之后也报错,’PDOException’ with message ‘could not find driver’PDOException’ with message ‘could not find driver 检测环境: 首先php.ini已经开启了extension=php_pdo_pgsql.dll和extension=php_pgsql.dll扩展已经打开,但是不...

function.registerOutParameter(1, Types.BIGINT); function.setLong(2, 1L); function.execute(); returnfunction.getLong(1); } } ); assertEquals(Long.valueOf(2), commentCount); When calling a PostgreSQL function through the JDBC API, parameters must be supplied by index and not by name, as ...
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 $$ declare -- ... begin -- ... end; $$; PostgreSQL 11不知道出于什么原因,新增了两个语法create proced...
