to look at the new patch set (#2).
Change subject: UDU-1945 Add C++ example for non-unique PK
......................................................................
UDU-1945 Add C++ example for non-unique PK
This patch adds an example C++ file to showcase the main operations
performed on a table having non-unique primary key.
STDOUT of the example:
Created a client connection
Created the schema:
(
non_unique_key INT32 NOT NULL,
auto_incrementing_id INT64 NOT NULL,
int_val INT32 NOT NULL,
PRIMARY KEY (non_unique_key, auto_incrementing_id)
)
Created the table
Inserted some row(s) into a table:
(int32 non_unique_key=3, int64 auto_incrementing_id=1, int32 int_val=0)
(int32 non_unique_key=3, int64 auto_incrementing_id=2, int32 int_val=1)
(int32 non_unique_key=3, int64 auto_incrementing_id=3, int32 int_val=2)
(int32 non_unique_key=4, int64 auto_incrementing_id=4, int32 int_val=0)
(int32 non_unique_key=1, int64 auto_incrementing_id=1, int32 int_val=0)
(int32 non_unique_key=1, int64 auto_incrementing_id=2, int32 int_val=1)
(int32 non_unique_key=1, int64 auto_incrementing_id=3, int32 int_val=2)
(int32 non_unique_key=2, int64 auto_incrementing_id=4, int32 int_val=0)
(int32 non_unique_key=2, int64 auto_incrementing_id=5, int32 int_val=1)
(int32 non_unique_key=2, int64 auto_incrementing_id=6, int32 int_val=2)
Demonstrating scanning ...
Scanned some row(s) from table, WHERE non_unique_key = 1:
(int32 non_unique_key=1, int64 auto_incrementing_id=1, int32 int_val=0)
(int32 non_unique_key=1, int64 auto_incrementing_id=2, int32 int_val=1)
(int32 non_unique_key=1, int64 auto_incrementing_id=3, int32 int_val=2)
Demonstrating UPDATE ...
Updated row(s), WHERE non_unique_key = 1 AND int_val = 2,\
to int_val = 98
