Update statement working in SQL Developer but not in C# -


i have small update query works in sql developer.

update people set months = 8 number = 599

fairly straight forward. , works - works in c#. problem moment want use parameters (which works on number not on months) stop working.

i have code in c#:

 using (oracleconnection con = new oracleconnection(connectionstring))         {             con.open();             oraclecommand command = con.createcommand();             command.commandtype = commandtype.text;             command.commandtext = "update people " +                               "set months = :months " +                               "where number = :number";             command.parameters.add(":number", oracledbtype.int32).value = number;             command.parameters.add(":months", oracledbtype.int32).value = months;              command.executenonquery();         }

they both of type number in oracle, , i've tried changing oracledbtype decimal, , pretty without success. odd thing is, :number parameters works, months doesn't updated (it won't crash, doesn't update). if change :months parameter, static value 7 - work.

you should add parameters without leading ':' (look here), try this:

using (oracleconnection con = new oracleconnection(connectionstring)) {     con.open();     oraclecommand command = con.createcommand();     command.commandtype = commandtype.text;     command.commandtext = "update people" +                       "set months = :months " +                       "where number = :number";     command.parameters.add("number", oracledbtype.int32).value = number;     command.parameters.add("months", oracledbtype.int32).value = months;      command.executenonquery(); }

also missing space after :months in query.

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
