ScriptUtils#splitSqlScript cannot deal with semicolons in stored procedures [SPR-15438]

[spring-projects-issues]

Phil Webb opened SPR-15438 and commented

Originally raised with Spring Boot the org.springframework.jdbc.datasource.init.ScriptUtils#splitSqlScript method cannot deal with semicolons that are part of a stored procedure.

For example:

CREATE FUNCTION count_clients() RETURNS integer
    LANGUAGE plpgsql
    AS $$begin
  select count(*) from clients;
end;$$;

Affects: 4.3.7

Like #19952, this is hard to address by default. Using a different quoting syntax or a different separator configuration is the easiest way out here for the time being.

Juergen Hoeller  fake separator is not cool. For example in my case app get schema sql file outside from app. And schema valid, but have sql triggers which does not correct compile by

I wonder whether the org.flywaydb.core.internal.database package can be leveraged. I believe there's about 6K+ lines of code the sole purpose of which is just to deal with this issue for about a dozen database engines.

See https://github.com/flyway/flyway/tree/e3c9adaac18f46017ad524cbe0df26d13ab33c00/flyway-core/src/main/java/org/flywaydb/core/internal/database for more details.

jhvhs hm...looks like acceptable for me. But I think that spring community will be glad if we fix this ticket

My solution: set spring.datasource.separator=^^^ END OF SCRIPT ^^^ .

By this setting, ScriptUtils does not separate the content of the SQL file into multiple statements.

ScriptUtils (spring version 5.2.5.RELEASE) failed parsing the following:

CREATE FUNCTION public.add_user(user_name character varying, user_id integer) RETURNS void
    LANGUAGE plpgsql SECURITY DEFINER
    AS $$DECLARE
BEGIN
	INSERT INTO tbl_users (username, id) VALUES(user_name, user_id);
END$$;

with error:

org.springframework.jdbc.datasource.init.ScriptStatementFailedException: Failed to execute SQL script statement....nested exception is org.postgresql.util.PSQLException: Unterminated dollar quote started at position....Expected terminating $$

Is there a solution for this, yet?

Great. Really works!

Hi team,
I am still not able to use ScriptUtils to execute a stored procedure. Receiving stacktrace that says "You have an error in your SQL Syntax" . Is there any way to resolve it?

Can you share the entire procedure, I am still not able to work it out
