[英]PHP Syntax Error with Postgresql INSERT query
我已經使用了幾個小時的代碼,只是看不到哪里有錯誤。 這是令人討厭的代碼
$answercreatequery = pg_query("INSERT INTO answer (answerid, questionid, adescription, afilelocation, iscorrect) VALUES( default, '".$thisquestionid."', '".$adescription1."', '".$afilelocation."', '".$iscorrect1."' ");
這是報告的錯誤
警告:pg_query()[function.pg-query]:查詢失敗:錯誤:輸入行1末尾的語法錯誤:...打開,不正確)VALUES(默認值,'37','kyfhdkj','none', 167行/ceri/homes1/m/mtp4/public_html/mmp/Quizmaker/Clientside/questioncreatescript.php中的^
我想知道是否缺少一些簡單的東西? 我懷疑這是因為$ iscorrect1是boolean類型,並且我嘗試了多種編輯方式,但是仍然遇到相同的錯誤。
/ d答案表
Column | Type | Modifiers
---------------+------------------------+-----------------------------------------------------------
answerid | integer | not null default nextval('answer_answerid_seq'::regclass)
questionid | integer | not null
adescription | character varying(200) | not null
afilelocation | character varying(200) | not null
iscorrect | boolean | not null
Indexes:
"answer_pkey" PRIMARY KEY, btree (answerid)
Foreign-key constraints:
"answer_questionid_fkey" FOREIGN KEY (questionid) REFERENCES question(questionid)
您在查詢末尾忘記了)
:
$answercreatequery = pg_query("INSERT INTO answer (answerid, questionid, adescription, afilelocation, iscorrect) VALUES( default, '".$thisquestionid."', '".$adescription1."', '".$afilelocation."', '".$iscorrect1."' ");
........................................................................................................................................................................................................insert ) here ^
除此之外,您可以簡單地省略要使用默認值的列:
$answercreatequery = pg_query("INSERT INTO answer
(questionid, adescription, afilelocation, iscorrect) VALUES
('".$thisquestionid."', '".$adescription1."', '".$afilelocation."', '".$iscorrect1."')");
另外,您應該真正使用pg_query_params
(而不是轉義或具有sql注入孔):
$answercreatequery = pg_query_params('INSERT INTO answer
(questionid, adescription, afilelocation, iscorrect) VALUES ($1, $2, $3, $4)',
array($thisquestionid, $adescription1, $afilelocation, $iscorrect1));
這樣做還使您的代碼更具可讀性。
