Java Class Reference 246 err DhSQLException Writes a message to the log. The following Java classes write to the log: • SQLIStatement • SQLPStatement • SQLCursor • DhSQLResult Set • DhSQLException Extends the general java.lang. exception class to provide detail about errors in SQL statement execution. Any such errors raise an exception with an argument that is an SQLException class object. The getDiagnostics() method retrieves details of the error. Constructors public DhSQLException(int ecode, String errMsg) Parameters ecode errMsg The error number associated with the exception condition. The error message associated with the exception condition. Example In this example, the DhSQLException constructor creates an exception object called excep and then throws the excep object under all conditions: CREATE PROCEDURE sp1_02() BEGIN // raising exception DhSQLException excep = new DhSQLException(666,new String ("Entered the tst02 procedure")); if (true) throw excep; END DhSQLException.getDiagnostics Returns the requested detail about an exception. Format public String getDiagnostics(int diagType)
Returns Java Class Reference A string containing the information specified by the diagType parameter, as shown in Table 55. Parameters Throws diagType One of the argument values listed in Table 55. DhSQLException Example This code fragment illustrates DhSQLException.getDiagnostics: DhSQLResultSet Table 55: Argument values for DhSQLException.getDiagnostics Argument value Returns RETURNED_SQLSTATE The SQLSTATE returned by execution of the previous SQL statement MESSAGE_TEXT The condition indicated by RETURNED_SQLSTATE CLASS_ORIGIN Not currently used; always returns NULL SUBCLASS_ORIGIN Not currently used; always returns NULL try { SQLIStatement insert_cust = new SQLIStatement ( "INSERT INTO customer VALUES (1,2) "); } catch (DhSQLException e) { errstate = e.getDiagnostics (RETURNED_SQLSTATE) ; errmesg = e.getDiagnostics (MESSAGE_TEXT) ; . . . } Provides the stored procedure with a result set to return to the application that called the procedure. The Java code in a stored procedure does not explicitly create DhSQLResultSet objects. Instead, when the SQL server creates a Java class from a CREATE PROCEDURE statement that contains a Result clause, it implicitly instantiates an object of type DhSQLResultSet, and calls it SQLResultSet. 247
