Pull request overview
This PR fixes a bug in the Oracle driver where lowercase table names were not supported. The issue stemmed from the driver removing all double quotes from SQL statements, which prevented Oracle from preserving case-sensitive identifiers (Oracle uses double quotes to maintain case sensitivity; without them, identifiers are converted to uppercase).
Key Changes:
- Removed the code in
oracle_do_filter.gothat stripped all double quotes from SQL statements - Updated test utilities to use double-quoted table names to preserve case sensitivity

背景：在Oracle中，双引号用于标识区分大小写的标识符，包括表名。当表名用双引号括起来时，Oracle会保留其大小写，否则，Oracle会将标识符转换为大写
问题：oracle_do_filter.go文件DoFilter函数中newSql, err = gregex.ReplaceString(""", "", newSql)会将sql语句中“”全部删除，导致无法支持表名为小写的表。
解决：删除newSql, err = gregex.ReplaceString(""", "", newSql)
