Yes, the sql_yacc.y is used to generate the sql parser. The
parser is used more to "run" the sql rather than to break it into its
tokens. Using the lex files would be closer to your stated goals. The
file lex.h in the same directory as sql_yacc.y contains all the tokens
mysql uses to break apart an SQL statement. sql_lex.cc is the lexer for
mysql, although it is non-trivial code. If your needs are for your
editor to fully understand the SQL statement, look into the lex files.
If your editor only needs to color code stuff, you could possibly get
away with just using the published list of mysql keywords for
highlighting.-----Original Message----- From: Carl Karsten [mailto:[EMAIL PROTECTED] Sent: Sunday, November 09, 2003 12:49 AM To: [EMAIL PROTECTED] Subject: sql parser I am looking for code that will take an SQL command and break it into it's parts. I have found some attempts, but none that use the code from an actual SQL engine, and big surprise, they don't work 100%. I have a few goals: 1) developer tool: cut/paste the SQL command and get a pretty format display - color, each component on a separate line, sub selects indented, etc. How often have you done this by hand and missed a paren? 2) part of an app: user is given a form with a bunch of textbox's. The form has a 'basic query' and each textbox has properties defining how to augment the basic query. For each input the user gives, augment the query. This would be much easier if I had something to break the basic query up into it's parts. I am guessing that such a thing does exist, so before I go spelunking through the source code, perhaps someone can point me somewhere. It looks like sql_yacc.y is what is used to define the syntax that MySql uses. It has been a while sense I took a compiler class, so forgive my ignorance. is sql_yacc.y used to generate the parser which is then compiled, or is it used at runtime? The goal is to be able to hook into the MySql code without having to copy it. That way as MySql evolves, so will my tool. http://www.personnelware.com/carl/resume.html -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe: http://lists.mysql.com/[EMAIL PROTECTED] -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe: http://lists.mysql.com/[EMAIL PROTECTED]
