SQLSTATE [42883]：未定义的函数，您可能需要添加显式类型强制转换

Question

I'm using Laravel with postgres and i'm having this error:

SQLSTATE[42883]: Undefined function: 7 ERROR: function paymentrun(integer, date, double precision, text) does not exist LINE 1: SELECT paymentRun( ^ HINT: No function matches the given name and argument types. You might need to add explicit type casts. (SQL: SELECT paymentRun( :buyer_id::integer, :payment_date::DATE, :paid_amount::double precision, :paydetails::text);)

Where I have this function: EDIT::the function is way bigger, but i think it's not needed to show

CREATE FUNCTION "paymentRun"(buyer_id integer, payment_date DATE, paid_amount double precision, payDetails text) RETURNS VOID AS
$$
DECLARE
row_STab "SearchTable"%rowtype;
curProd  "KeysForSale"%rowtype;
totalPrice double precision;
returnedPID integer;
BEGIN

And I'm calling the fuction in this way:

DB::select("SET TRANSACTION ISOLATION LEVEL SERIALIZABLE;");
DB::select('BEGIN TRANSACTION;');

$sendToSQL = '';

for($i = 0; $i<session('cart_number'); $i++)
    $sendToSQL .= '(' . $cart_array[$i] . '),';
$sendToSQL = rtrim($sendToSQL,",");
$sendToSQL .= ';';

DB::select('INSERT INTO "SearchTable"(product_id) VALUES' . $sendToSQL);

//DB::select(DB::raw('SELECT paymentRun'))->where(Auth::id(), date('Y/m/d'),'PayPal', 10000, 'qualquer');
DB::select('SELECT paymentRun(
    :buyer_id::integer,
    :payment_date::DATE,
    :paid_amount::double precision,
    :paydetails::text);', 

    ['buyer_id' => Auth::id(), 
     'payment_date' => date('Y/m/d'),
     'paid_amount' => 10000, 
     'paydetails' =>'qualquer'
 ]);
//DB::select('DELETE FROM "SearchTable";');
DB::select('COMMIT;');

What i'm doing wrong? I tried several aways, but no a single one has come to a decent result.

Thanks

You created the function with the name within double quotes and different cases.

CREATE FUNCTION "paymentRun" ...

If you do so casing matters when the object is subsequently addressed. So you need to change

DB::select('SELECT paymentRun(

to

DB::select('SELECT "paymentRun"(

in order to address the function correctly.
