Oracle stored procedure -PLS-00103: Encountered the symbol \"\"



I am trying to call a Oracle Stored procedure from Microsoft flow, but keep getting below error. I tried creating a dummy procedure with no paramters and not much code inside, still getting same error. I tried calling other existing procedure in database which is working and still getting same error whichever procedure I call.


I was able to call stored procedure in my trial version before in my personal laptop's database and I dont think this issue is due to specific error in procedure, since same error is thrown for all procedure.


Can you somoene please assist with this error?

Hi @itsgowthaman,


I am afraid there is an unexpected character in your code.


When you create the Stored procedure, have you used the escape character (“\”)?


Please take this doc on Oracle Database for a reference:

Hi @v-yamao-msft,


That was my first thought, but this character is not present in the procedure. Also same error is being thrown for any procedure which I use from flow, but it is working fine when I execute the procedure directly from Toad. I think the issue is not with the procedure. I tested by creating a dummy procedure as below, this is very simple one with no logic. I still get the same error when I call it from flow.


create or replace procedure generate_errors_test

On further testing, this is an issue with connecting to older version of Oracle. The issue I faced is with Oracle 10g. No matter which procedure I called, same error is returning. So there is some settings or calling style which is causing this issue. Not sure if there is any solution to this.


I tried calling a procedure from Oracle 12C and it is working without any issues.
