| <h2 id="introduction">2. Introduction</h2> |
| <div class="sectionbody"> |
| <div class="paragraph"> |
| <p>This chapter introduces stored procedures in Java (SPJs) in Trafodion |
| and covers these topics:</p> |
| </div> |
| <div class="sect2"> |
| <h3 id="what-is-an-spj">2.1. What Is an SPJ?</h3> |
| <div class="paragraph"> |
| <p>A stored procedure is a type of user-defined routine (UDR) that operates |
| within a database server and typically performs SQL operations on a |
| database. The database server contains information about the stored |
| procedure and controls its execution. A client application executes a |
| stored procedure by issuing an SQL CALL statement. Unlike a user-defined |
| function, which returns a value directly to the calling application, a |
| stored procedure returns each output value to a dynamic parameter in its |
| parameter list or returns a set of values to a result set array.</p> |
| </div> |
| <div class="paragraph"> |
| <p>Trafodion supports stored procedures written in the Java |
| programming language. The Trafodion implementation of stored procedures |
| complies mostly, unless otherwise specified, with SQL/JRT (Java Routines |
| and Types), which extends the ANSI SQL/Foundation standard. A stored |
| procedure in Java (SPJ) is a Java method contained in a Java archive |
| (JAR) file on Trafodion, registered in the database, and |
| executed by the database engine when a client application issues a CALL |
| statement.</p> |
| </div> |
| <div class="paragraph"> |
| <p>The body of a stored procedure consists of a public, static Java method |
| that returns void. These Java methods, called <em>SPJ methods</em>, are |
| contained in classes within JAR files on the cluster hosting Trafodion.</p> |
| </div> |
| <div class="paragraph"> |
| <p>An SPJ method must be registered as a stored procedure in the database before a |
| client application can execute it with a CALL statement. You upload the SPJ to |
| the cluster where Trafodion is running |
| and then you register the SPJ as a library object using the |
| <a href="http://trafodion.apache.org/docs/sql_reference/index.html#create_library_statement">CREATE LIBRARY</a> |
| statement. Next, you register the library object using the |
| <a href="http://trafodion.apache.org/docs/sql_reference/index.html#create_procedure_statement">CREATE PROCEDURE</a> |
| statement.</p> |
| </div> |
| </div> |
| <div class="sect2"> |
| <h3 id="benefits-of-spjs">2.2. Benefits of SPJs</h3> |
| <div class="paragraph"> |
| <p>SPJs provide an efficient and secure way to implement business logic in |
| the database. SPJs offer these advantages:</p> |

| <div class="sect3"> |
| <h4 id="java-methods-callable-from-sql">2.2.1. Java Methods Callable From SQL</h4> |
| <div class="paragraph"> |
| <p>With support for SPJs, Java methods are callable from any client |
| application that connects to Trafodion. For example, you can |
| invoke the same SPJ method from JDBC client applications and ODBC client |
| applications. By using the database engine to invoke Java methods, you |
| can extend the functionality of the database and share business logic |
| among different applications.</p> |
| </div> |
| <div class="paragraph"> |
| <p>For more information, see <a href="#execute-spjs">Execute SPJs</a>.</p> |
| </div> |
| </div> |
| <div class="sect3"> |
| <h4 id="common-packaging-technique">2.2.2. Common Packaging Technique</h4> |
| <div class="paragraph"> |
| <p>Different applications can invoke the same SPJ to perform a common |
| business function. By encapsulating business logic in an SPJ, you can |
| maintain consistent database operations and avoid duplicating code in |
| applications.</p> |
| </div> |
| <div class="paragraph"> |
| <p>Applications that call SPJs are not required to know the structure of |
| the database tables that the SPJ methods access. The application does |
| not need to use any table or column names; it needs only the name of the |
| stored procedure in the CALL statement. If the table structure changes, |
| you might need to change the SPJ methods but not necessarily the CALL |
| statements within each application.</p> |
| </div> |
| </div> |
| <div class="sect3"> |
| <h4 id="security">2.2.3. Security</h4> |
| <div class="paragraph"> |
| <p>By using SPJs, you can conceal sensitive business logic inside SPJ |
| methods instead of exposing it in client applications. You can also |
| grant privileges to execute an SPJ to specific users and restrict the |
| privileges of other users. For more information, see |
| <a href="#grant-privileges">Grant Privileges</a></p> |
| </div> |
| </div> |
| <div class="sect3"> |
| <h4 id="increased-productivity">2.2.4. Increased Productivity</h4> |
| <div class="paragraph"> |
| <p>Use SPJs to reduce the time and cost of developing and maintaining |
| client applications. By having several applications call the same SPJ, |
| you need only change the SPJ method once when business rules or table |
| structures change instead of changing every application that calls the |
| SPJ.</p> |
| </div> |
| <div class="paragraph"> |
| <p>Using the Java language to implement stored procedures increases |
| productivity. Given the popularity of the Java language, you can |
| leverage the existing skill set of Java programmers to develop SPJs.</p> |
| </div> |
| <div class="paragraph"> |
| <p>The portability of the Java language enables you to write and compile |
| Java class files for SPJs once and deploy them anywhere.</p> |
| </div> |
| </div> |
| <div class="sect3"> |
| <h4 id="portability">2.2.5. Portability</h4> |
| <div class="paragraph"> |
| <p>Because SPJ methods are written in Java, and SPJs conform to the ANSI |
| SQL standard, SPJs are portable across different database servers. With |
| minimal changes to SPJ methods, you can port existing SPJ JAR files from |
| another database server to Trafodion and register the methods |
| as stored procedures in a Trafodion database. You can also port client |
| applications that call SPJs in other databases to Trafodion SQL with |
| minimal changes to the CALL statements in the application.</p> |

| <h4 id="no-transaction-required">8.2.2. No Transaction Required</h4> |
| <div class="paragraph"> |
| <p>In some cases, you might not want the SPJ method to inherit the |
| transaction from the calling application. Instead, you might want the |
| stored procedure to manage its own transactions or to run without a |
| transaction. Not inheriting the calling application’s transaction is |
| useful in these cases:</p> |
| </div> |
| <div class="ulist"> |
| <ul> |
| <li> |
| <p>The stored procedure performs several long-running operations, such as |
| multiple DDL or table maintenance operations, on the database. In this |
| case, you might want to commit those operations periodically from within |
| the SPJ method to avoid locking tables for a long time.</p> |
| </li> |
| <li> |
| <p>The stored procedure performs certain SQL operations that must run |
| without an active transaction. For example, INSERT, UPDATE, and DELETE |
| statements with the WITH NO ROLLBACK option are rejected when a |
| transaction is already active, as is the case when a stored procedure |
| inherits a transaction from the calling application. The PURGEDATA |
| utility is also rejected when a transaction is already active.</p> |
| </li> |
| <li> |
| <p>The stored procedure does not access the database. (For an example, |
| see the <a href="#totalprice-procedure">TOTALPRICE Procedure</a>.) In this case, |
| the stored procedure does not need to inherit the transaction from the |
| calling application. By setting the stored procedure’s transaction |
| attribute to NO TRANSACTION REQUIRED, you can avoid the overhead of |
| the calling application’s transaction being propagated to the stored |
| procedure.</p> |
| </li> |
| </ul> |
| </div> |
| <div class="paragraph"> |
| <p>In these cases, you should set the stored procedure’s transaction |

| <div class="paragraph"> |
| <p>If you select <code>No</code> for the Transaction Required attribute when creating a |
| stored procedure and if the SPJ method creates a JDBC default |
| connection, then that connection has autocommit enabled by default. You |
| can either use the autocommit transactions or disable autocommit |
| (<code>conn.setAutoCommit(false);</code>) and use the JDBC transaction methods, |
| <code>Connection.commit()</code> and <code>Connection.rollback()</code>, to commit or roll back |

| <h3 id="troubleshooting-common-problems">9.1. Troubleshooting Common Problems</h3> |
| <div class="paragraph"> |
| <p>To resolve problems that occur when you register or execute an SPJ, |
| follow these guidelines:</p> |
| </div> |
| <div class="ulist"> |
| <ul> |
| <li> |
| <p>Note the SQLCODE or SQLSTATE value of the error messages and locate |
| the information in the |
| <a href="http://trafodion.apache.org/docs/messages_guide/index.html">[Trafodion Messages Manual</a>], |
| which provides cause, effect, and recovery information for all SQL errors.</p> |
| </li> |
| <li> |
| <p>Check that the user has the appropriate permissions to create or call |
| the SPJ. See these sections:</p> |
| <div class="ulist"> |
| <ul> |
| <li> |
| <p><a href="#required-privileges-for-creating-or-dropping-an-spj">Required Privileges for Creating or Dropping an SPJ</a>.</p> |
| </li> |
| <li> |
| <p><a href="#required-privileges-for-calling-an-spj">Required Privileges for Calling an SPJ</a>.</p> |
| </li> |
| </ul> |
| </div> |
| </li> |
| <li> |
| <p>Check the code of the SPJ method. See <a href="#develop-spj-methods">Develop SPJ Methods</a>. |
| Fix any problems.</p> |
| </li> |
| <li> |
| <p>If you successfully compiled, deployed, and registered the SPJ but are |
| receiving errors when calling the SPJ, check that the output parameters |
| in the Java method are specified as arrays. See |
| <a href="#returning-output-values-from-the-java-method">Returning Output Values From the Java Method</a>.</p> |
| </li> |
| <li> |
| <p>Verify that someone did not alter the library by selecting a JAR file |
| that contains a different class name, method name, or method signature |
| than the original JAR file, without dropping and re-creating the SPJ.</p> |
| </li> |
| <li> |
| <p>Check the syntax of the CALL statement in the application. See |
| <a href="#execute-spjs">Execute SPJs</a>. Fix any problems.</p> |
| </li> |
| <li> |
| <p>If the SPJ is supposed to return result sets, but the result sets are |
| not being returned to the calling application, then check that the SPJ method |
| does not explicitly close a <code>java.sql.Connection</code> object. See |
| <a href="#Use-of-java-sql-Connection-Objects">Use of java.sql.Connection Objects</a>.</p> |
| </li> |
| <li> |
| <p>If a <code>java.lang.ArrayIndexOutOfBoundsException</code> occurs, then check that the |
| SPJ method is not trying to insert more than one array element into a |
| <code>java.sql.ResultSets[]</code> array. For more information, see |
| <a href="#returning-stored-procedure-result-sets">Returning Stored Procedure Result Sets</a>.</p> |
| </li> |
| <li> |
| <p>To identify Java-related errors, execute the SPJ method outside Trafodion |
| by invoking the Java method directly in a Java application that you run on a |
| client workstation, using the Trafodion JDBC Type-4 driver to connect to Trafodion.</p> |
| </li> |
| <li> |
| <p>If you are using JDBC tracing and logging, then follow these guidelines:</p> |
| <div class="ulist"> |
| <ul> |
| <li> |
| <p>Execute the SPJ method outside the database by invoking the Java |
| method directly from a Java application that you run on a client |
| workstation, using the Trafodion JDBC Type-4 driver to connect to the Trafodion |
| platform.</p> |
| </li> |
| <li> |
| <p>Verify that the file directory specified in the <code>T4LogFile</code> property |
| exists on the client workstation and that you have write access to it.</p> |
