Thread: passing parameters to function

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
 
PS: Looking for an early reply

You would have to set them to NULL

Hi All,
 
Is there anyway i can get the list of parameters which the store proc accepts from the java end after i make the prepareCall.
 
Thks

You might want to look at
DatabaseMetaData dbmd = con.getMetaData();
ResultSet your_funk_args = dbmd.getProcedureColumns(...);
I dont know (or looked) if it is supported by the current
7.4 pgsql jdbc.
