As you know by now, each time an application opens a cursor, Oracle hard-parses the statement on the first encounter (or if the statement is no longer in the shared pool), and then soft-parses it on subsequent encounters. In this section, we will look at how a statement is parsed within a loop. To see the inner workings of our programs in this chapter, we will set SQL trace from Java by executing the method JDBCUtil.startTrace(). The method startTrace() of the JDBCUtil class is as follows: /** * starts SQL trace for a JDBC program. The SQL trace is * automatically disabled when the program ends */ public static void startTrace ( Connection connection ) throws SQLException { String setTimedStatisticsStmt = "alter session set timed_statistics=true"; String setTraceStmt = "alter session set events '10046 trace name context forever, level 12'"; Statement stmt = null; try { stmt = connection.createStatement(); stmt.execute( setTimedStatisticsStmt ); stmt.execute( setTraceStmt ); } finally { stmt.close(); } } As you can see, the method simply sets the timed statistics on and alters the session to enable SQL tracing. Subsequently, we will use tkprof to look at the trace file data. The concept of soft and hard parses in a loop is illustrated by the following program, DemoParse, with interspersed explanatory comments: import java.sql.SQLException; import java.sql.ResultSet; import java.sql.Connection; import java.sql.PreparedStatement; import oracle.jdbc.OracleTypes; import book.util.JDBCUtil; class DemoParse { public static void main(String args[]) throws Exception { Connection conn = null; PreparedStatement pstmt = null;

PreparedStatement pstmt1 = null; ResultSet rset = null; ResultSet rset1 = null; try { // get connection - auto commit is off conn = (Connection) JDBCUtil. getConnection("scott", "tiger", args[0]); We start the trace, as we will use tkprof to demonstrate the concepts: JDBCUtil.startTrace( conn ); The first statement string has a tag enclosed within /*+ and */: String stmtString = "select /*+ prepareStatement() within loop */" + " empno, job from emp where ename = "; Why do we need the tag We need it because we will be comparing execution of the same statement (select empno, job from emp where ename= ) for two cases: Case 1: We execute prepareStatement() within a for loop that loops five times. Case 2: We execute prepareStatement() outside a for loop that loops five times. When we look at the tkprof output, we need to distinguish between the two cases; otherwise, tkprof will combine the statistics for both at one place, since the statements will be identical. When we use a tag of the form /*+ <some identifying string that is not a valid hint>*/, Oracle treats the tag as a no-op SQL hint (i.e., a null operation) and ignores it since it is not a valid hint, but still treats any two statements that have a different tag as different. Using a tag like this is a very useful trick to compare identical statements in a SQL trace, but distinguish their alternative execution profiles in the trace file. This technique will become clearer once we look at the tkprof output.

In this script, two variables of type Number and Date are instantiated and assigned initial values. After that, the DisplayTypeInfo function is called to display the type information for these two variables. The getType method is called here for the type of the variable followed by the getTypeName to get the name of the variable type. As you can see in Figure 4-5, the type contains more information than the type name.

Note Instead of enclosing the tag between /*+ and */, you could enclose it within /* and */, which constitutes a comment. However, this works only in 9i; in 10g, as an optimization, Oracle strips out the comments before processing the statement, thus defeating the purpose of the tag.

From the tag value of prepareStatement() within loop, we can make out that we are going to execute case 1 first. We do that in the following code by executing our statement five times within the loop (note that the invocation of prepareStatement() is within the for loop): for( int i=0; i < 5; i++ ) { pstmt = conn.prepareStatement( stmtString ); pstmt.setString( 1, "SCOTT" ); rset = pstmt.executeQuery(); while( rset.next() )

{ } } Next, we prepare an identical statement except for the tag, which indicates that this time we prepare the statement outside the loop: stmtString = "select /*+ prepareStatement() outside loop */ " + "empno, job from emp where ename = "; pstmt1 = conn.prepareStatement( stmtString ); for( int i=0; i < 5; i++ ) { pstmt1.setString( 1, "SCOTT" ); rset1 = pstmt1.executeQuery(); while( rset1.next() ) { } } } finally { // release resources associated with JDBC in the finally clause. JDBCUtil.close( rset ); JDBCUtil.close( pstmt ); JDBCUtil.close( rset1 ); JDBCUtil.close( pstmt1 ); JDBCUtil.close( conn ); } } } Following is the relevant portion of the tkprof output for case 1: select /*+ prepareStatement() within loop */ empno, job from emp where ename = :1
