ORA-06537 OUT bind variable bound to an IN position

Question

Sir,
we have migrated our database from oracle 9i to 10g (Release 10.1.0.2.0)..
but while executing a procedure we are getting the following error
ORA-06537:OUT bind variable bound to an IN position
this same procedure is not throwing any error wen we connect the 9i database
we are giving two parameters for this procedure
in that second one is an IN OUT Parameter
another procedure which use the same parameters working properly in 10g and 9i.
we are using PowerBuilder 10 as front end
plz help me to get ride of this prob...

Answer 1

You get that error even in 9i if the parameters to the procedure calls are not bound correctly. Check the powerbuilder application to make sure it is binding the parameter types correctly.
