Dameng database case_sensitive

[baoyachi]

The docker image :dm_single run default ignore case_sensitive, and when there are double quotes in the table creation statement, it will not be converted to uppercase by default. If there are no double quotes, it will be automatically converted to uppercase.
E.g:

CREATE TABLE SYSDBA.T4 (
	id INT NOT NULL,
	useR_ID CHARACTER VARYING(8188) NOT NULL,
	user_name TEXT NOT NULL,
	"role" TEXT NOT NULL,
	"source" TEXT NOT NULL
);

Then,query table describe about code:

let cursor_impl = connection.conn.execute(r#"SELECT A.NAME, A.ID, A.COLID, A.TYPE$, A.LENGTH$, A.SCALE, A.NULLABLE$, A.DEFVAL, B.NAME AS TABLE_NAME, B.CRTDATE FROM SYSCOLUMNS AS a LEFT JOIN SYSOBJECTS AS B ON A.id = B.id WHERE B.name IN ('T4') AND B.SCHID IN (SELECT ID FROM SYSOBJECTS WHERE name = 'SYSDBA');"#, ()).unwrap().unwrap();

cursor_impl.print_all_tables().unwrap();

Output:
