Pentaho Flow Input->Output->Input not working


Pentaho Flow Input->Output->Input not working

I wish this helpful for you Found the issue. Inserting the "select values" was the solution but I forgot to reset the step after it to get data from the "select value" step, so it was still trying to get data from the step before that.

Hope that helps Transformations in Kettle run asynchronously, so you're probably looking into needing a job for this.
Files to create Create a transformation that performs the SQL query you're looking for and populates a variable based on the result Create a transformation that pulls data from the Excel file, using the variable populated as the filename Create a job that executes the first transformation, then steps into the second transformation

wish helps you It's because of lazy conversion. Turn it off. This is behaving exactly as designed - although admittedly the error and user experience could be improved.
Lazy conversion must not be used when you need to access the field value in your transformation. That's exactly what it does. The default should probably be off rather than on.

With these it helps I have a stored procedure with two varchar input parameters and one int output parameter. The idea is that I pass in the table name and an unique string, check the table to see if that string already exists in the table and return the id of that record if it does. Currently the sproc looks like: , Try a stored procedure like the following:
code :
DROP PROCEDURE IF EXISTS `sp_GetRecordID`;

DELIMITER //

CREATE PROCEDURE `sp_GetRecordID`(
  `tablename_In` VARCHAR(64),
  `formSecret_In` VARCHAR(32),
  OUT `id_Out` BIGINT UNSIGNED
)
BEGIN
  SET @`query` := CONCAT('SELECT `id` INTO @`id_Out`
                          FROM ', `tablename_In` ,' 
                          WHERE `formSecret` = \'', `formSecret_In`, '\'');
  PREPARE `stmt` FROM @`query`;
  EXECUTE `stmt`;
  SET `id_Out` := @`id_Out`,
       @`query` := NULL;
  DEALLOCATE PREPARE `stmt`;
END//

DELIMITER ;

it helps some times You can rename the fields right in your MS-Excel-Input step, and you can reorder the fields in Text-File-Output. Also, a Select-Values step allows you to rename and reorder fields in one sweep on the Select & Alter tab.
