/**
|
|
|
50 |
* MDB OCI8 driver
|
|
|
51 |
*
|
|
|
52 |
* Notes:
|
|
|
53 |
* - when fetching in associative mode all keys are uppercased which is not the
|
|
|
54 |
* intenteded behavior. Due to BC issues this will not be changed in MDB 1.x
|
|
|
55 |
* however.
|
|
|
56 |
*
|
|
|
57 |
* - createDatabase and dropDatabase are not supported
|
|
|
58 |
*
|
|
|
59 |
* - Text fields with unspecified length limit are created as VARCHAR with an
|
|
|
60 |
* optional limit that may not exceed 4000 characters.
|
|
|
61 |
*
|
|
|
62 |
* - date fields are emulated with date fields with time set to 00:00:00.
|
|
|
63 |
time fields are emulated with date fields with the day set to 0001-01-01.
|
|
|
64 |
*
|
|
|
65 |
* - The numRows method is emulated by fetching all the rows into memory.
|
|
|
66 |
* Avoid using it if for queries with large result sets.
|
|
|
67 |
*
|
|
|
68 |
* - Oracle does not provide direct support for returning result sets restricted
|
|
|
69 |
to a given range. Such support is emulated in the MDB oci8 driver.
|
|
|
70 |
*
|
|
|
71 |
* - Storing data in large object fields has to be done in two phases: first the
|
|
|
72 |
fields are initialized using a INSERT or UPDATE query that sets the fields
|
|
|
73 |
to an empty value, then the data values are uploaded to the large objects
|
|
|
74 |
returned by reference from the executed queries.
|
|
|
75 |
* Besides the fact that only INSERT and UPDATE queries are supported to
|
|
|
76 |
upload large object data values, only UPDATE queries that affect only one
|
|
|
77 |
row will set the large object fields correctly.
|
|
|
78 |
*
|
|
|
79 |
* - The driver alterTable method does not implement table or column renaming.
