Re: passing parameters to function

 

Hi All,

 

Suppose I have a store proc which accepts 4 input parameters

and I do a CallableStatement.setObject( 1, "..,,," );

and execute the query .

 

 

 CallableStatement functionCall = dbCon_.prepareCall("{call test1( ?,?,?,?) }");  
  functionCall.setObject( "param1","A10001" );
  functionCall.setObject( "param2","19830529" );
  functionCall.execute();

Exception raised

 

java.sql.SQLException: No value specified for parameter 3
        at com.mysql.jdbc.PreparedStatement.fillSendPacket(PreparedStatement.java:1253)
        at com.mysql.jdbc.PreparedStatement.fillSendPacket(PreparedStatement.java:1201)
        at com.mysql.jdbc.PreparedStatement.execute(PreparedStatement.java:710)
        at com.mysql.jdbc.CallableStatement.execute(CallableStatement.java:520)
 

 

during runtime. Should i set the other 2 input parameters to null,

even when I dont want to pass these parameters to the SP.

In this statement call test1( ?,?,?,?), should the number of parameters be the number

of parameters which the store procedure accepts or the number of parameters that i want

to pass.  How should this be done when my SP accepts 4 parameters and i want to pass

only any two of them

 

Thks
