- * if the deprecated option <var>optimize</var> gets set to
- * <samp>portability</samp>:
- * + oci8
- *
- *
- * <samp>DB_PORTABILITY_RTRIM</samp>
- * right trim the data output by <kbd>get*()</kbd> <kbd>fetch*()</kbd>
- *
- *
- * <samp>DB_PORTABILITY_DELETE_COUNT</samp>
- * force reporting the number of rows deleted
- *
- * Some DBMS's don't count the number of rows deleted when performing
- * simple <kbd>DELETE FROM tablename</kbd> queries. This portability
- * mode tricks such DBMS's into telling the count by adding
- * <samp>WHERE 1=1</samp> to the end of <kbd>DELETE</kbd> queries.
- *
- * This mode gets automatically turned on in the following databases
- * if the deprecated option <var>optimize</var> gets set to
- * <samp>portability</samp>:
- * + fbsql
- * + mysql
- * + mysqli
- * + sqlite
- *

- *

- * + oci8
- *
- *
- * <samp>DB_PORTABILITY_ERRORS</samp>
- * makes certain error messages in certain drivers compatible
- * with those from other DBMS's
- *
- * + mysql, mysqli: change unique/primary key constraints
- * DB_ERROR_ALREADY_EXISTS -> DB_ERROR_CONSTRAINT
- *
- * + odbc(access): MS's ODBC driver reports 'no such field' as code
- * 07001, which means 'too few parameters.' When this option is on
- * that code gets mapped to DB_ERROR_NOSUCHFIELD.
- * DB_ERROR_MISMATCH -> DB_ERROR_NOSUCHFIELD
- *
- * <samp>DB_PORTABILITY_NULL_TO_EMPTY</samp>
- * convert null values to empty strings in data output by get*() and
- * fetch*(). Needed because Oracle considers empty strings to be null,
- * while most other DBMS's know the difference between empty and null.
- *
