   Flex/Bison: Unable to parse multiple SQL   
   12 Jan 08 14:00:31   
   
   From: sumeet.sl@gmail.com   
      
   Hi,   
      
   I have created an SQL parser, which works fine when I enter commands   
   from the terminal. When I enter multiple commands, it parses and   
   executes each one of them. No problems with grammar, etc. But when I   
   try to read them from a file, it just parses the first command and   
   ignores the rest of them, an ftell on yyin after the yyparse()   
   indicates that it has read the entire file.   
      
   In the flex file, I'm switching to another state when I encounter a   
   ';' In that state, if I get a '\n', I switch to the default state and   
   return 0. In the default state, all \n's are ignored.   
      
   I have tried a lot of things, but I'm unable to parse all the commands   
   from the file. Any suggestions to solve this problem?? Please help!   
      
   Thanks,   
   Sumeet
