[BUG] JSQLParser 4.7-SNAPSHOT(+4.6) PostgreSQL(+others) Enum error on ReferentialAction.Type.valueOf() when delete/update keyword is lowercase

[daredevil2033]

Failing SQL Feature:

Parsing CreateTable statement fails if the "delete/update" keyword in outline foreign key constraint is lowercase.
Technically not supported but in practice everything except this works in either case.

SQL Example:

CREATE TABLE DATABASES
(
NAME VARCHAR(50) NOT NULL,
OWNER VARCHAR(50) NOT NULL,
PRIMARY KEY (NAME),
FOREIGN KEY(OWNER) REFERENCES USERS (USERNAME) ON delete CASCADE
);

Software Information:

• JSqlParser version 4.6 and 4.7-SNAPSHOT
• Database PostgreSQL (and probably most others)

Problem

CCJSqlParser.java lines 17281, 17302, 20970, 20991 in 4.7-SNAPSHOT:
fkIndex.setReferentialAction(ReferentialAction.Type.valueOf(tk.image), action);
Lines 20900 and 20921 are affected as well:
alterExp.setReferentialAction(ReferentialAction.Type.valueOf(tk.image), action);

Solution

changing tk.image to tk.image.toUpperCase() should work

Thanks, I will fix that tomorrow.

Thank you again, there were quite a number of similar problematic calls to other Enum.
I have refactored all of them into Enum.from(...) with an implementation like:

public static Type from(String name) {
    return Enum.valueOf(Type.class, name.toUpperCase());
}
