Given this Java regex code for a PSQL statement, I'm having some issues trying to match everything but the comments in the statements. This is not getting the lines with the comments in them.
^(?!.*?(?:-- [a-z]*-[a-z]*: [a-zA-z]*)).*$
This is the PSQL:
CREATE TABLE "test_table" (
"user_id" serial PRIMARY KEY,
"username" VARCHAR (50) UNIQUE NOT NULL, -- foreign-key: t_supply_type
"password" VARCHAR (50) NOT NULL,
"email" VARCHAR (355) UNIQUE NOT NULL, -- foreign-key: t_supply_type
"created_on" TIMESTAMP NOT NULL,
"last_login" TIMESTAMP
);
What am I missing?
One simple approach for your exact data would be to just remove all occurrences of --
until the end of the line. Consider:
String line = "\"username\" VARCHAR (50) UNIQUE NOT NULL, -- foreign-key: t_supply_type";
line = line.replaceAll("\\s*--.*$", "");
System.out.println(line);
This prints:
"username" VARCHAR (50) UNIQUE NOT NULL,
Assuming you have already read the entire SQL query into a single string, the above replacement should also still work.
