73 | Used as: |

75 | on_connect_call => 'datetime_setup' |
193590c2 |

77 | In L<connect_info|DBIx::Class::Storage::DBI/connect_info> to set the C<DATE> and |
78 | C<DATETIME> formats. |
193590c2 |
79 | |
b0a4cf8e |
80 | Sets the following environment variables: |
193590c2 |
81 | |
b0a4cf8e |
82 | GL_DATE="%m/%d/%Y" |
83 | GL_DATETIME="%Y-%m-%d %H:%M:%S%F5" |
193590c2 |
84 | |
b0a4cf8e |
85 | The C<DBDATE> and C<DBCENTURY> environment variables are cleared. |
86 | |
87 | B<NOTE:> setting the C<GL_DATE> environment variable seems to have no effect |
88 | after the process has started, so the default format is used. The C<GL_DATETIME> |
89 | setting does take effect however. |
90 | |
91 | The C<DATETIME> data type supports up to 5 digits after the decimal point for |
92 | second precision, depending on how you have declared your column. The full |
93 | possible precision is used. |
94 | |
95 | The column declaration for a C<DATETIME> with maximum precision is: |
96 | |
97 | column_name DATETIME YEAR TO FRACTION(5) |
193590c2 |
98 | |
b0a4cf8e |
99 | The C<DATE> data type stores the date portion only, and it B<MUST> be declared |
100 | with: |
101 | |
102 | data_type => 'date' |
103 | |
104 | in your Result class. |
105 | |
106 | You will need the L<DateTime::Format::Strptime> module for inflation to work. |
