## Description
- This PR introduces support for prepared statements to the Oracle
integration that is currently behind a feature flag.
- Fixed a bug with PL/SQL cmd due to semicolon.
- Fixed a bug with reading Array type.
- The following tasks will be taken up separately and will not be part
of this PR. They will be resolved before lifting the feature flag:
- DB structure and query templates
- Error messages infra
- JUnit TC
- The following data types were tested: `char, varchar, array, int,
float, double, raw, timestamp, timestamp_tz, interval` . The following
cmd was used to test the feature:
```
select * from TYPESTEST4 where c_varchar2={{'varchar2'}}
and c_nvarchar2={{'nvarchar2'}}
and c_number={{1}}
and c_float={{11.22}}
and c_date={{'2002-10-03'}}
and c_binary_float={{11.22}}
and c_binary_double={{11.22}}
and c_timestamp=TO_TIMESTAMP({{'01-01-1997 09:26:50.124'}})
and c_timestamp_tz=TO_UTC_TIMESTAMP_TZ({{"1997-01-01T09:26:56.66+02:00"}})
and c_interval_day=NUMTODSINTERVAL({{1}}, {{'HOUR'}})
and c_char={{'char '}}
and c_raw=utl_raw.cast_to_raw({{'raw'}})
```
- `JSON` type could not be tested because it was only recently
introduced in version 21c. However, the Oracle test instance credentials
available on Notion are for 19c. Tracking it
[here](https://github.com/appsmithorg/appsmith/issues/20796).
Fixes#20533
## Type of change
- New feature (non-breaking change which adds functionality)
## How Has This Been Tested?
- Manual
## How to Test
```
(1) Create a Table with various data types like:
create table typestest4 (
c_varchar2 varchar2(20),
c_nvarchar2 nvarchar2(20),
c_number number,
c_float float,
c_date date,
c_binary_float binary_float,
c_binary_double binary_double,
c_timestamp timestamp,
c_timestamp_tz timestamp with time zone,
c_timestamp_ltz timestamp with local time zone,
c_interval_year interval year to month,
c_interval_day interval day to second,
c_raw raw(256),
c_rowid rowid,
c_urowid urowid,
c_char char(256),
c_nchar nchar(256),
c_clob clob,
c_nclob nclob,
c_blob blob
)
(2) Insert data into the table:
insert into TYPESTEST4 values (
'varchar2',
'nvarchar2',
1,
11.22,
'03-OCT-02',
11.22,
11.22,
TIMESTAMP'1997-01-01 09:26:50.124',
TIMESTAMP'1997-01-01 09:26:56.66 +02:00',
TIMESTAMP'1999-04-05 8:00:00 US/Pacific',
INTERVAL '1' YEAR(3),
INTERVAL '1' HOUR,
utl_raw.cast_to_raw('raw'),
'000001F8.0001.0006',
'000001F8.0001.0006',
'char',
'nchar',
'clob',
'nclob',
utl_raw.cast_to_raw('raw')
)
(3) Run the following select cmd with prepared statement toggle on:
select * from TYPESTEST4 where c_varchar2={{'varchar2'}}
and c_nvarchar2={{'nvarchar2'}}
and c_number={{1}}
and c_float={{11.22}}
and c_date={{'2002-10-03'}}
and c_binary_float={{11.22}}
and c_binary_double={{11.22}}
and c_timestamp=TO_TIMESTAMP({{'01-01-1997 09:26:50.124'}})
and c_timestamp_tz=TO_UTC_TIMESTAMP_TZ({{"1997-01-01T09:26:56.66+02:00"}})
and c_interval_day=NUMTODSINTERVAL({{1}}, {{'HOUR'}})
and c_char={{'char '}}
and c_raw=utl_raw.cast_to_raw({{'raw'}})
```
