query建议使用 ` ` 引用

Line 85 in 7a9f824

query := "SELECT COLUMN_NAME, DATA_TYPE, COLUMN_KEY, " +

建议改为

query := `SELECT COLUMN_NAME, DATA_TYPE, COLUMN_KEY,
		IS_NULLABLE, COLUMN_TYPE, COLUMN_COMMENT 
		FROM COLUMNS WHERE TABLE_SCHEMA = ? AND TABLE_NAME = ?`

如果使用 " " 引号，可能出现 dbModel: GetColumns err: Error 1054: Unknown column '...' in 'field list'的 error
