If I actually run it with property: spring.datasource.url = jdbc:h2:file:C:/Projects/Workspace IT Academy/M13 Simple Spring HTTP Service/H2DB, instead of jdbc:h2:mem:h2db;DB_CLOSE_DELAY=-1 it will start the app until I try to connect to http://localhost:8080/, then it breaks, and gives me a similar error, telling me that the table does not exist. Ideally, I would like to run it with datasource jdbc:h2:mem:h2db.
I have tried IntelliJ and SpringToolSuit and they give the exact same error. I have seen quite a few other threads about this, but I have not identified the error yet. Could it be that my Jar’s are corrupted? Is it a matter of versions? I have checked and rechecked dependencies, properties..tryed adding dev-tools, and spring-boot-starter-tomcat…but it gives me also errors…There must be something I am missing. Any help would be much appreciated!

From the stacktrace it is evident that, wehen springboot is starting up , it is trying to execute the schema.sql to create the tables that are necessary for the application and failing due to the syntax error :
ot/autoconfigure/jdbc/DataSourceConfiguration$Hikari.class]: Initialization of bean failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.boot.autoconfigure.jdbc.DataSourceInitializerInvoker': Invocation of init method failed; nested exception is org.springframework.jdbc.datasource.init.ScriptStatementFailedException: Failed to execute SQL script statement #2 of URL [file:/C:/Projects/Workspace%20IT%20Academy/M13SimpleSpringHTTPService/target/classes/schema.sql]: CREATE TABLE TBL_EMPLOYEES ( id INT AUTO_INCREMENT PRIMARY KEY, first_name VARCHAR(250) NOT NULL, last_name VARCHAR(250) NOT NULL, job_role VARCHAR(250) NOT NULL, salary DOUBLE(4,2) NOT NULL ); nested exception is org.h2.jdbc.JdbcSQLSyntaxErrorException: Syntax error in SQL statement "CREATE TABLE TBL_EMPLOYEES ( ID INT AUTO_INCREMENT PRIMARY KEY, FIRST_NAME VARCHAR(250) NOT NULL, LAST_NAME VARCHAR(250) NOT NULL, JOB_ROLE VARCHAR(250) NOT NULL, SALARY DOUBLE(4,[*]2) NOT NULL )"; expected ")"; SQL statement:
I think the issue is the DOUBLE datatype that you provided for salary column in your create table query. As per the H2 documentation it does not take a scale parameter. So , the syntax that you provided in the create table query might be wrong which causes the issue. Try using a numeric instead to confirm.
Try(I haven’t tried executing the query myself) :
DROP TABLE IF EXISTS TBL_EMPLOYEES; CREATE TABLE TBL_EMPLOYEES ( id INT AUTO_INCREMENT PRIMARY KEY, first_name VARCHAR(250) NOT NULL, last_name VARCHAR(250) NOT NULL, job_role VARCHAR(250) NOT NULL, salary DECIMAL(6,2) NOT NULL );
