Using mysql_fetch_array function if submit an query with left join
es.:
select * from A left join B on (A.index_c=B.index_c)
the resulting array contains fields of table B with NULL value if
condition is not matched
es.:
A table:
----------------------------
| index | index_c | X | P |
----------------------------
| 1 | 1 | 1 | 1 |
----------------------------
| 1 | NULL | 1 | 1 |
----------------------------
B table:
-------------------
| index_c | P | D |
-------------------
| 1 | 1 | 2 |
-------------------
Array result:
---------------------------------
| index | index_c | X | P | D |
---------------------------------
| 1 | 1 | 1 | 1 | 2 |
---------------------------------
| 1 | NULL | 1 |NULL|NULL|
---------------------------------
with command line mysql:
---------------------------------
| index | index_c | X | P | D |
---------------------------------
| 1 | 1 | 1 | 1 | 2 |
---------------------------------
| 1 | NULL | 1 | 1 | |
