如何在 postgres 中调用带参数的存储过程函数 sql

Question

我正在为 如何使用传递参数调用 PostgreSQL 存储过程函数而苦苦挣扎。我不知道，我弄错了传递参数调用 function.Please 建议我。

这是我的php文件calling.php

      include('connection.php');
      echo  $hud='15';
      echo $phc='80001';

      echo $Firstdate='2015-08-01';
      echo $Seconddate='2015-10-01';
      echo $Todate='2015-10-31';
      $dvn_sql =<<<EOF
      select * from prisonparam($hud text
      ,$phc text
      ,$Firstdate Date
      ,$Seconddate Date
      ,$Todate Date);
      EOF;
   $dvn_ret = pg_query($db, $dvn_sql);
      while($row = pg_fetch_array($dvn_ret))
      {   
      echo $ben_st=trim($row['sc']);
      echo $round=trim($row['scupto']);
      }

这是我的存储过程函数

       CREATE OR REPLACE FUNCTION prisonparam(dvn_cd text
      ,phc_cd text
      ,Firstdate Date
      ,Seconddate Date
      ,Todate Date) 
      RETURNS table (round text,sc bigint,scupto bigint)
      AS $$

      WITH a
      AS (
      SELECT round AS round
      ,Sum(ben_sc) AS SC

FROM prison_issue
WHERE (
        DATE BETWEEN Firstdate
            AND Todate
        )
    AND dvn_cd = dvn_cd
    AND phc_cd = phc_cd

GROUP BY round ORDER BY round
)
,b
 AS (
SELECT round AS round_up
    ,Sum(ben_sc) AS SC_up


 FROM prison_issue
WHERE (
        DATE BETWEEN Seconddate
            AND Todate
        )
    AND dvn_cd = dvn_cd
    AND phc_cd = phc_cd
GROUP BY round ORDER BY round
)
  SELECT b.round_up AS round
 ,coalesce(a.sc, 0) AS SC
 ,coalesce(b.sc_up, 0) AS SCUPTO

 FROM a
 RIGHT JOIN b ON a.round = b.round_up

 $$ LANGUAGE sql;

错误是

Warning: pg_query(): Query failed: 
ERROR: function prisonparam(integer, integer, integer, integer, integer) does not exist 
LINE 1: select * from prisonparam(15,80001, 2015-08-01,2015-10... ^
HINT: No function matches the given name and argument types. You might need to add explicit type casts.

Answer 1

尝试替换查询

select * from prisonparam($hud text
      ,$phc text
      ,$Firstdate Date
      ,$Seconddate Date
      ,$Todate Date);

与

select * from prisonparam('$hud','$phc','$Firstdate','$Seconddate' ,'$Todate');

或

$dvn_sql ="select * from prisonparam('".$hud."','".$phc."','".$Firstdate."','".$Seconddate."','".$Todate."')";
