Java调用Oracle存储Package

Oracle的包Package中能够有不少存储，可经过该包的总调入口在java中直接调用。

//java调用oracle的package代码
public boolean cal() throws java.lang.Exception { CallableStatement cstmt = null; String procedure = "{call G_IMPORT_CAL.g_entry(?,?,?) }"; cstmt = conn.prepareCall(procedure); cstmt.setString(1,organkey); cstmt.setString(2,this.getT18_task_fac().getGranularity()); cstmt.setString(3,this.getT18_task_fac().getStatisticdate()); cstmt.executeUpdate(); cstmt.close(); return true; }
