Wie informix Datum Fehler beheben?

Question

Ich habe die unten SQL-Abfrage in meinem Code

String sql = "select t.card_num, \n" +

Jetzt, als ich das Abfrageergebnis in meinem SQL-Editor ausführen , erhalte ich eine SQLException:

"ERROR java.sql.SQLException: It is not possible to convert between the specified types" 

kann jemand bitte helfen Sie mir, habe ich versucht, Anführungszeichen um die Datumsfelder setzen. Aber das hat nicht funktioniert.

Answer 1

Auch wenn sie nicht mit Jonathan Leffler Kommentar über das eigentliche Problem nicht einverstanden mit dem Lärm verdeckt wird, denke ich, Ihr Problem ist diese Linie:

" where t.trans_date between "+ getParam("jrs.param$p_startDate") +" and "+ getParam("jrs.param$p_endDate")+"\n" 

, die diese parst:

where t.trans_date between 2016-09-26 and 2016-10-10 

Datum Felder müssen in Anführungszeichen eingeschlossen sein, damit sie nicht als arithmetisch interpretiert werden (2016 - 9 - 26 = 1981), daher wird Ihr Prädikat auf:

where t.trans_date between 1981 and 1996 

reduziert

... eindeutig nicht das, was Sie wollen, und das erklärt die Beschwerde des Servers über Datentypen. So versuchen entkommen Zitate hinzu:

" where t.trans_date between \""+ getParam("jrs.param$p_startDate") +"\" and \""+ getParam("jrs.param$p_endDate")+"\"\n" 

Als Nebenwirkung, Informix ist Agnostiker über einfache oder doppelte Anführungszeichen, so können Sie Ihren Code viel mehr lesbar mit einfachen Anführungszeichen, wo immer Sie sich gerade doppelt entkam haben -quotes. Andere Engines, die sich damit befassen (zum Beispiel SQL Server), erwarten sowieso einfache Anführungszeichen für Strings.
