X-Git-Tag: v1.70~233 X-Git-Url: http://git.shadowcat.co.uk/gitweb/gitweb.cgi?a=commitdiff_plain;h=fe3ae272650700ebb68d179d50b7d137f2d8e855;p=dbsrgits%2FSQL-Abstract.git Fixed behaviour of 'literal SQL with bind' feature (ie. \[$sql, @bind]) to expect @bind in the same format as returned by ->where(). Added some tests for the above feature. --- diff --git a/lib/SQL/Abstract.pm b/lib/SQL/Abstract.pm index 3e6e5cf..dc28d48 100644 --- a/lib/SQL/Abstract.pm +++ b/lib/SQL/Abstract.pm @@ -110,18 +110,7 @@ sub _insert_HASHREF { # explicit list of fields and then values my @fields = sort keys %$data; - my ($sql, @bind); - { # get values (need temporary override of bindtype to avoid an error) - local $self->{bindtype} = 'normal'; - ($sql, @bind) = $self->_insert_ARRAYREF([@{$data}{@fields}]); - } - - # if necessary, transform values according to 'bindtype' - if ($self->{bindtype} eq 'columns') { - for my $i (0 .. $#fields) { - ($bind[$i]) = $self->_bindtype($fields[$i], $bind[$i]); - } - } + my ($sql, @bind) = $self->_insert_values($data); # assemble SQL $_ = $self->_quote($_) foreach @fields; @@ -137,18 +126,48 @@ sub _insert_ARRAYREF { # just generate values(?,?) part (no list of fields) $self->{bindtype} ne 'columns' or belch "can't do 'columns' bindtype when called with arrayref"; + # fold the list of values into a hash of column name - value pairs + # (where the column names are artificially generated, and their + # lexicographical ordering keep the ordering of the original list) + my $i = "a"; # incremented values will be in lexicographical order + my $data_in_hash = { map { ($i++ => $_) } @$data }; + + return $self->_insert_values($data_in_hash); +} + +sub _insert_ARRAYREFREF { # literal SQL with bind + my ($self, $data) = @_; + + my ($sql, @bind) = @${$data}; + $self->_assert_bindval_matches_bindtype(@bind); + + return ($sql, @bind); +} + + +sub _insert_SCALARREF { # literal SQL without bind + my ($self, $data) = @_; + + return ($$data); +} + +sub _insert_values { + my ($self, $data) = @_; + my (@values, @all_bind); - for my $v (@$data) { + foreach my $column (sort keys %$data) { + my $v = $data->{$column}; $self->_SWITCH_refkind($v, { ARRAYREF => sub { if ($self->{array_datatypes}) { # if array datatype are activated push @values, '?'; - push @all_bind, $v; + push @all_bind, $self->_bindtype($column, $v); } else { # else literal SQL with bind my ($sql, @bind) = @$v; + $self->_assert_bindval_matches_bindtype(@bind); push @values, $sql; push @all_bind, @bind; } @@ -156,6 +175,7 @@ sub _insert_ARRAYREF { # just generate values(?,?) part (no list of fields) ARRAYREFREF => sub { # literal SQL with bind my ($sql, @bind) = @${$v}; + $self->_assert_bindval_matches_bindtype(@bind); push @values, $sql; push @all_bind, @bind; }, @@ -165,7 +185,7 @@ sub _insert_ARRAYREF { # just generate values(?,?) part (no list of fields) #TODO in SQLA >= 2.0 it will die instead belch "HASH ref as bind value in insert is not supported"; push @values, '?'; - push @all_bind, $v; + push @all_bind, $self->_bindtype($column, $v); }, SCALARREF => sub { # literal SQL without bind @@ -174,7 +194,7 @@ sub _insert_ARRAYREF { # just generate values(?,?) part (no list of fields) SCALAR_or_UNDEF => sub { push @values, '?'; - push @all_bind, $v; + push @all_bind, $self->_bindtype($column, $v); }, }); @@ -186,19 +206,6 @@ sub _insert_ARRAYREF { # just generate values(?,?) part (no list of fields) } -sub _insert_ARRAYREFREF { # literal SQL with bind - my ($self, $data) = @_; - return @${$data}; -} - - -sub _insert_SCALARREF { # literal SQL without bind - my ($self, $data) = @_; - - return ($$data); -} - - #====================================================================== # UPDATE methods @@ -229,14 +236,16 @@ sub update { } else { # literal SQL with bind my ($sql, @bind) = @$v; + $self->_assert_bindval_matches_bindtype(@bind); push @set, "$label = $sql"; - push @all_bind, $self->_bindtype($k, @bind); + push @all_bind, @bind; } }, ARRAYREFREF => sub { # literal SQL with bind my ($sql, @bind) = @${$v}; + $self->_assert_bindval_matches_bindtype(@bind); push @set, "$label = $sql"; - push @all_bind, $self->_bindtype($k, @bind); + push @all_bind, @bind; }, SCALARREF => sub { # literal SQL without bind push @set, "$label = $$v"; @@ -536,18 +545,19 @@ sub _where_hashpair_HASHREF { ($sql, @bind) = $self->_where_field_op_ARRAYREF($k, $op, $val); }, - SCALARREF => sub { # CASE: col => {op => \$scalar} + SCALARREF => sub { # CASE: col => {op => \$scalar} (literal SQL without bind) $sql = join ' ', $self->_convert($self->_quote($k)), $self->_sqlcase($op), $$val; }, - ARRAYREFREF => sub { # CASE: col => {op => \[$sql, @bind]} + ARRAYREFREF => sub { # CASE: col => {op => \[$sql, @bind]} (literal SQL with bind) my ($sub_sql, @sub_bind) = @$$val; + $self->_assert_bindval_matches_bindtype(@sub_bind); $sql = join ' ', $self->_convert($self->_quote($k)), $self->_sqlcase($op), $sub_sql; - @bind = $self->_bindtype($k, @sub_bind); + @bind = @sub_bind; }, UNDEF => sub { # CASE: col => {op => undef} : sql "IS (NOT)?
