NAME

SQL::Object::Interp - Yet another SQL condition builder with SQL::Interp

SYNOPSIS

    use SQL::Object::Interp qw/isql_obj/;
    
    my $sql = isql_obj('foo.id =', \1, 'AND', 'bar.name =', \'nekokak');
    $sql->as_sql; # 'foo.id = ? AND bar.name = ?'
    $sql->bind; # qw/1 nekokak/
    
    my $class = 5;
    $sql->and('baz.class =', \$class);
    $sql->as_sql; # 'foo.id = ? AND bar.name = ? AND baz.class = ?'
    $sql->bind; # qw/1 nekokak 5/
    
    my $bar_age = 33;
    $sql->or('bar.age =', \$bar_age);
    $sql->as_sql; # '(foo.id = ? AND bar.name = ? AND baz.class = ?) OR bar.age = ?'
    $sql->bind; # qw/1 nekokak 5 33/
    
    my $cond = isql_obj('foo.id =', \2);
    $sql = $sql | $cond;
    $sql->as_sql; # '((foo.id = ? AND bar.name = ? AND baz.class = ?) OR bar.age = ?) OR (foo.id = ?)'
    $sql->bind; # qw/1 nekokak 5 33 2/
    
    $cond = isql_obj('bar.name =',\'tokuhirom');
    $sql = $sql & $cond;
    $sql->as_sql; # '((foo.id = ? AND bar.name = ? AND baz.class = ?) OR bar.age = ?) OR (foo.id = ?) AND bar.name = ?'
    $sql->bind; # qw/1 nekokak 5 33 2 tokuhirom/
    
    $sql = isql_obj('SELECT * FROM user WHERE ') + $sql;
    
    $sql->as_sql; # 'SELECT * FROM user WHERE ((foo.id = ? AND bar.name = ? AND baz.class = ?) OR bar.age = ?) OR (foo.id = ?) AND bar.name = ?'
    
    my $sql_no = isql_obj;

    $sql_no->as_sql; # 'foo.id = ?'
    $sql_no->bind; # 2

DESCRIPTION

SQL::Object::Interp is an extension of raw level SQL maker "SQL::Object".

SQL::Object::sql_obj is incompatible with SQL::Interp::sql_interp which returns ($stmt, @binds).

SQL::Object::Interp::isql_obj is a substitute of sql_obj which is compatible with SQL::Interp (like DBIx::Simple::iquery).

METHODS

SQL::Object::Interp inherits SQL::Object.

my $sql = isql_obj(args for sql_interp)

create SQL::Object::Interp's instance.

Uses SQL::Interp to generate $stmt, $bind(s). See SQL::Interp's documentation for usage information.

my $sql = SQL::Object->new(sql => $sql, bind => \@bind); # SQL::Object's method

create SQL::Object::Interp's instance

$sql = $sql->and(args for sql_interp)

compose sql. operation 'AND'.

$sql = $sql->or(args for sql_interp)

compose sql. operation 'OR'.

$sql = $sql->compose_and($sql)

compose sql object. operation 'AND'.

$sql = $sql->compose_or($sql)

compose sql object. operation 'OR'.

$sql->add_parens() # SQL::Object's method

bracket off current SQL.

$sql->as_sql() # SQL::Object's method

get sql statement.

$sql->bind() # SQL::Object's method

get sql bind variables.
