I'm trying to build a H2 database using Spring, but I'm running into errors. I've so far followed the steps from this channel, but I'm running into this error:
2022-12-30T22:04:01.054 11:00 WARN 18528 --- [ main] o.h.t.s.i.ExceptionHandlerLoggedImpl : GenerationTarget encountered exception accepting command : Error executing DDL "INSERT INTO courses VALUES (id, code, coursename) VALUES (1, 'CS150', 'Intro to Computer Science')" via JDBC Statement

SQL statement
INSERT INTO courses VALUES (id, code, coursename) VALUES (1, 'CS150', 'Intro to Computer Science')
I've tried changing what's in application.properties
, dependencies (javax to jakarta).
CodePudding user response:
Mistake in the SQL statement. Facepalm..
I missed the "caused by" in the error logs which helped answer the problem.
Caused by: org.h2.jdbc.JdbcSQLSyntaxErrorException: Syntax error in SQL statement "INSERT INTO courses VALUES (id, code, coursename) [*]VALUES (1, CS150, Intro to Computer Science)"; SQL statement:
Fixed SQL statement with:
INSERT INTO courses(id, code, coursename) VALUES (1, 'CS150', 'Intro to Computer Science')
