Re: [HACKERS] Definition of function base_yylex in version 8.1.4
I am trying to implement materialized views using trigger which will be used to maintain the views which will be generated. For this I am required to add a new command for the creation of a materialized view, which is already done by modifying the grammar in the gram.y file. However, I need to know where exactly the function base_yylex is defined. This function seems to return the next token from the command. Any help is appreciated, Ashish Mehra [EMAIL PROTECTED] wrote: Hi Sayali, What project is this that you are working on, any details that you provide will help Regards Ashish On 10/27/07, sayali k [EMAIL PROTECTED] wrote: Hi all, I am having a project in Postgres where I need to modify some code in the parser section of the code base.
