SQL::S...::Term(3pm)

💖 SQL::S...::Term — the tea ☕

okay bestie, sit down, because today we're talking about SQL::S...::Term(3pm) — that's the SQL::Statement::Term family, three whole modules of term-y goodness, all documented in this one page. it's giving "abstract base class energy" and honestly? we're obsessed. 🫶

---

✨ NAME ✨

SQL::Statement::Term — bestie, it's the base class for all terms. the blueprint. the blueprint-est. 👑

---

✨ SYNOPSIS ✨

# create a term with an SQL::Statement object as owner
my $term = SQL::Statement::Term->new( $owner );
# access the value of that term
$term->value( $eval );

---

✨ DESCRIPTION ✨

SQL::Statement::Term is an abstract base class providing the interface for all terms. it doesn't do the actual work itself, no ma'am — it's the vibe-setter, the group-chat admin, the one who says "here's the interface, y'all go implement it." 🎀

---

✨ INHERITANCE ✨

SQL::Statement::Term

---

✨ METHODS ✨

new

Instantiates a new term and stores a weak reference to the owner. lowkey important that it's weak, okay? 💅

value

Abstract method which will return the value of the term. it must be overridden by derived classes — like, if you don't override it, that's not a vibe. do not skip this step bestie. 🙈

DESTROY

Destroys the term and undefines the weak reference to the owner. clean exit, no loose ends, we love to see it. ✨

---

🌸 NAME 🌸

my $term = SQL::Statement::ConstantTerm->new( $owner, 'foo' );

---

🌸 DESCRIPTION 🌸

---

🌸 INHERITANCE 🌸

ISA SQL::Statement::Term

---

🌸 METHODS 🌸

new

Instantiates a new term and stores the constant to deliver and a weak reference to the owner. two things, one constructor, slay. 🫶

value

---

🦋 NAME 🦋

SQL::Statement::ColumnValue — the term for column values. it's the one that actually looks stuff up in your data, a real researcher, a real academic, a real "let me check my notes" girlie. 📚

---

🦋 SYNOPSIS 🦋

# create a term with an SQL::Statement object as owner
my $term = SQL::Statement::ColumnValue->new( $owner, 'id' );
# access the value of that term - returns the value of the column 'id'
# of the currently active row in $eval
$term->value( $eval );

---

🦋 DESCRIPTION 🦋

SQL::Statement::ColumnValue implements a term which will return the specified column of the active row. yes bestie, the active row, the row that's currently having its moment. 🌈

---

🦋 INHERITANCE 🦋
