Call DB procedure

Description

The Call DB Procedure transform allows you to execute a database procedure (or function) and get the result(s) back. With MySQL and JDBC, it is not possible to retrieve the result set of a stored procedure. Stored procedures and functions can only return values through their function arguments and those arguments must be defined in the Parameters section of the DB Procedure Call configuration.

Options

Option	Description
Transform name	Name of the transform; this name has to be unique in a single pipeline
Connection	Name of the database connection on which the procedure resides
Proc-name	Name of the procedure or function to call
Find it	Click to search on the specified database connection for available procedures and functions (Oracle and SQL Server only)
Enable auto	In some instances you want to perform updates
commit	in the database using the specified procedure. In that case you can either have the changes performed using auto-commit or not. If auto-commit is disabled, a single commit is being performed after the last row is received by this transform.
Result name	Name of the result of the function call; leave blank if this is a procedure
Result type	Type of the result of the function call; not used in case of a procedure.
Parameters	List of parameters that the procedure or function needs Field name: Name of the field. Direction: Can be either IN (input only), OUT (output only), INOUT (value is changed on the database). Type: Used for output parameters so that Hop knows what returns
Get Fields	Fills in all the fields in the input streams to make your life easier; delete the lines you don’t need and re-order the remaining lines
