Bonjour à tous,
 
Je commence en même temps le c et le precompilateur suscité d'oracle...
 
J'ai tatonné pas mal mais là j'aurais besoin d'un coup de main de la part d'une bonne âme  :D .
Je n'arrive pas à trouver d'explication aux erreurs qui me restent...

globalement deux erreurs quoi...
 
par ailleurs, la version linux du même precompilateur me retourne carrément :
 

Citation :

Error at line 202, column 2 in file /home/oracle/grant_role.pc
}
.1
PCC-S-02010, found end-of-file while scanning string literal
Error at line 0, column 0 in file grant_role.pc
PCC-F-02102, Fatal error while doing C preprocessing


 
 :??:  
 
Je vois pas ou, et en plus, comment ce fait-il que la version windows ne m'insulte pas de la même maniére ?
 
A vot bon coeur messieurs, dames...

Fais plutôt :
 

Code :
  1. EXEC SQL SELECT COUNT(*)
  2. INTO :rec_nr
  3. FROM SYS.ALL_TABLES
  4. WHERE owner = :owner_name;


 
Pour les curseurs, il faut faire :
 

Code :
  1. EXEC SQL DECLARE CURSOR my_cursor FOR
  2. SELECT TABLE_NAME FROM SYS.ALL_TABLES
  3. WHERE owner = :owner_name;
  5. EXEC SQL OPEN my_cursor;
