See SQL::Abstract for hash options. .Sp .Vb 1 \& $class\->search_where(\e%where,\e%attrs); .Ve .Sp Takes hash reference to specify \s-1WHERE\s0 clause. See SQL::Abstract for hash options. Takes a hash reference to specify additional query attributes. Class::DBI::AbstractSearch uses these attributes: .RS 4 .IP "\(bu" 4 \&\fBorder_by\fR .Sp Array reference of fields that will be used to order the results of your query. .IP "\(bu" 4 \&\fBlimit_dialect\fR .Sp Scalar, \s-1DBI\s0 handle, object class, etc. that describes the syntax model for a \s-1LIMIT/OFFSET SQL\s0 clause. Please see SQL::Abstract::Limit for more information. .IP "\(bu" 4 \&\fBlimit\fR .Sp Scalar value that will be used for \s-1LIMIT\s0 argument in a query. .IP "\(bu" 4 \&\fBoffset\fR .Sp Scalar value that will be used for \s-1OFFSET\s0 argument in a query. .RE .RS 4 .Sp Any other attributes are passed to the SQL::Abstract::Limit constructor, and can be used to control how queries are created. For example, to use '\s-1AND\s0' instead of '\s-1OR\s0' by default, use: .Sp .Vb 1 \& $class\->search_where(\e%where, { logic => \*(AqAND\*(Aq }); .Ve .RE .SH "AUTHOR" .IX Header "AUTHOR" Tatsuhiko Miyagawa with some help from cdbi-talk mailing list, especially: .PP .Vb 3 \& Tim Bunce \& Simon Wilcox \& Tony Bowden .Ve .PP This library is free software; you can redistribute it and/or modify it under the same terms as Perl itself. .SH "SEE ALSO" .IX Header "SEE ALSO" Class::DBI, SQL::Abstract, SQL::Abstract::Limit
