In Linux, the database name, table name, column name, And alias are case-sensitive: 1. The database name and table name are case sensitive; 2. Table aliases are case sensitive; 3. The column name and column alias are case-insensitive in all cases; 4. Variable names are case sensitive; MySQL is case insensitive in windows. Therefore, in different operating systemsProgramAnd the database can run normally, the best way is to co

I have seen a lot of such situations. Since we all know that we should not use reserved words, why? DBAs or other users who are used to using command lines and w

very troublesome. Because the database name is also written into the control file and the control file is stored in binary format, you cannot modify the control file content. Assume that you have modified the database name in the parameter file, that is, the value of DB_NAME. But at Oracle startup, because DB_NAME In the parameter file is inconsistent with the database name in the control file, causing database startup failure, a ORA-01103 error is returned.
