Postgresql错误代码：错误编号对应的错误信息
|
Postgresql执行器在执行SQL时，如果出现无法执行的SQL，将会报告出错误信息。 错误代码使用一般在编写PL/pgSQL函数时，使用EXCEPTION抛出异常信息时。 如下例子： --例一：使用EXCEPTION捕获异常 create or replace function fn_exception() returns void as $$ declare x int default 1; y int; begin x = x + 1; y = x / 0; exception when division_by_zero then -- 与 when SQLSTATE '22012' then 等价 raise notice '除数不能为0'; end; $$ language plpgsql; --例二：不使用EXCEPTION捕获异常 create or replace function fn_no_exception() returns void as $$ declare x int default 1; y int; begin x = x + 1; y = x / 0; end; $$ language plpgsql; 当我们调用例一函数时： 当我们调用例二函数时 由上面结果我们可以看到：当例一捕获异常时，调用函数不会报错（虽然该函数存在错误，而是输出异常中的提示内容）， 而例二没有捕获异常，当我们调用例二函数时，将导致函数执行失败，抛出ERROR：除数为零 的错误信息。 报错信息编号：22012 与报错详细信息：division by zero，我们可以通过下面错误信息对应列表查到。 EXCEPRION中异常捕获when后面的内容为列表内容。
