15 | DBIx::Class::Storage::DBI::SQLAnywhere - Driver for Sybase SQL Anywhere |
db8f81cf |
16 | |
17 | =head1 DESCRIPTION |
18 | |
19 | This class implements autoincrements for Sybase SQL Anywhere and selects the |
20 | RowNumberOver limit implementation. |
21 | |
22 | You need the C<DBD::SQLAnywhere> driver that comes with the SQL Anywhere |
23 | distribution, B<NOT> the one on CPAN. It is usually under a path such as: |
24 | |
2b0076be |
25 | /opt/sqlanywhere11/sdk/perl |
26 | |
27 | Recommended L<DBIx::Class::Storage::DBI/connect_info> settings: |
28 | |
29 | on_connect_call => 'datetime_setup' |

90 | Used as: |
91 | |
92 | on_connect_call => 'datetime_setup' |
93 | |
94 | In L<DBIx::Class::Storage::DBI/connect_info> to set the date and timestamp |
95 | formats (as temporary options for the session) for use with |
96 | L<DBIx::Class::InflateColumn::DateTime>. |
97 | |
98 | The C<TIMESTAMP> data type supports up to 6 digits after the decimal point for |
99 | second precision. The full precision is used. |
100 | |
101 | The C<DATE> data type supposedly stores hours and minutes too, according to the |
102 | documentation, but I could not get that to work. It seems to only store the |
103 | date. |
104 | |
105 | You will need the L<DateTime::Format::Strptime> module for inflation to work. |
