JAVA调用存储过程

注意，以下使用数据库为sql2000，驱动jtds1.2.2 一、调用存储过程(无结果集返回) Connection connection = ConnectionHelper.getConnection(); CallableStatement callableStatement = connection.prepareCall("{ call procedureName(?,?) }"); callableStatement.setString(1, "xxxxxxxx"); callableStatement.setString(2, " ;xxxxxxxx"); callableStatement.execute(); //获得sql的消息并输出，这个估计很多人都需要 SQLWarning sqlWarning = callableStatement.getWarnings(); while (sqlWarning != null) { System.out.println("sqlWarning.getErrorCode() = " + sqlWarning.getErrorCode()); System.out.println("sqlWarning.getSQLState() = " + sqlWarning.getSQLState()); System.out.println("sqlWarning.getMessage() = " + sqlWarning.getMessage()); sqlWarning = sqlWarning.getNextWarning(); } //close ConnectionHelper.closeConnection(callableStatement, connection); 二、调用存储过程，返回sql类型数据（非记录集） Connection connection = ConnectionHelper.getConnection(); CallableStatement callableStatement = connection.prepareCall("{ call procedureName(?,?,?) }"); callableStatement.setString(1, "xxxxxxxx"); callableStatement.setString(2, "xxxxxxxx"); //重点是这句1 callableStatement.registerOutParameter(3, Types.INTEGER); callableStatement.execute(); //取返回结果,重点是这句2 //int rsCount = callableStatement.getInt(3); //close ConnectionHelper.closeConnection(callableStatement, connection); 三、重点来了，返回记录集，多记录集 注意，不需要注册返回结果参数，只需要在sql中select出结果即可 例如：select * from tableName 即可得到返回结果 Connection connection = ConnectionHelper.getConnection(); CallableStatement callableStatement = connection.prepareCall("{ call procedureName(?) }"); //此处参数与结果集返回没有关系 callableStatement.setString(1, "xxxxxxxx"); callableStatement.execute(); ResultSet resultSet = callableStatement.getResultSet(); //以上两个语句，可以使用ResultSet resultSet = callableStatement.executeQuery();替代 //多结果返回 ResultSet resultSet2; if (callableStatement.getMoreResults()) { resultSet2 = callableStatement.getResultSet(); while (resultSet2.next()) { } } //close ConnectionHelper.closeConnection(callableStatement, connection); 提示：多结果返回可以使用如下代码(以上主要让大家明白，单一结果和多结果的区别)： Boolean hasMoreResult = true; while (hasMoreResult) { ResultSet resultSet = callableStatement.getResultSet(); while (resultSet.next()) { } hasMoreResult = callableStatement.getMoreResults(); } ;xxxxxxxx"); callableStatement.execute(); //获得sql的消息并输出，这个估计很多人都需要 SQLWarning sqlWarning = callableStatement.getWarnings(); while (sqlWarning != null) { System.out.println("sqlWarning.getErrorCode() = " + sqlWarning.getErrorCode()); System.out.println("sqlWarning.getSQLState() = " + sqlWarning.getSQLState()); System.out.println("sqlWarning.getMessage() = " + sqlWarning.getMessage()); sqlWarning = sqlWarning.getNextWarning(); } //close ConnectionHelper.closeConnection(callableStatement, connection); 二、调用存储过程，返回sql类型数据（非记录集） Connection connection = ConnectionHelper.getConnection(); CallableStatement callableStatement = connection.prepareCall("{ call procedureName(?,?,?) }"); callableStatement.setString(1, "xxxxxxxx"); callableStatement.setString(2, "xxxxxxxx"); //重点是这句1 callableStatement.registerOutParameter(3, Types.INTEGER); callableStatement.execute(); //取返回结果,重点是这句2 //int rsCount = callableStatement.getInt(3); //close ConnectionHelper.closeConnection(callableStatement, connection); 三、重点来了，返回记录集，多记录集 注意，不需要注册返回结果参数，只需要在sql中select出结果即可 例如：select * from tableName 即可得到返回结果 Connection connection = ConnectionHelper.getConnection(); CallableStatement callableStatement = connection.prepareCall("{ call procedureName(?) }"); //此处参数与结果集返回没有关系 callableStatement.setString(1, "xxxxxxxx"); callableStatement.execute(); ResultSet resultSet = callableStatement.getResultSet(); //以上两个语句，可以使用ResultSet resultSet = callableStatement.executeQuery();替代 //多结果返回 ResultSet resultSet2; if (callableStatement.getMoreResults()) { resultSet2 = callableStatement.getResultSet(); while (resultSet2.next()) { } } //close ConnectionHelper.closeConnection(callableStatement, connection); 提示：多结果返回可以使用如下代码(以上主要让大家明白，单一结果和多结果的区别)： Boolean hasMoreResult = true; while (hasMoreResult) { ResultSet resultSet = callableStatement.getResultSet(); while (resultSet.next()) { } hasMoreResult = callableStatement.getMoreResults(); }
