All Implemented Interfaces:

FrostlakeVisitor<Expression>, org.antlr.v4.runtime.tree.ParseTreeVisitor<Expression>

public class ExpressionAstBuilder
extends FrostlakeBaseVisitor<Expression>

Builds Expression AST nodes directly from the ANTLR parse tree.

This replaces the round-trip in which an expression sub-tree was flattened back to source text (via getOriginalText) and then re-parsed, once per row, by the hand-rolled ExpressionParser. The grammar already parses every expression into a labeled parse tree; this visitor maps each labeled alternative of the expression rule to the corresponding Expression node. It mirrors SQLCommandVisitor (which builds statement-level objects) but is typed to produce Expression.

A few constructs intentionally fail loudly via notPorted(java.lang.String, org.antlr.v4.runtime.ParserRuleContext) because they are not row expressions that reach this builder — each is handled by another path: window OVER (resolved by the window operator before row evaluation), function named arguments (f(x => 1), used by table functions via TableFunctionOperator), bind variables (:name, substituted by the JDBC / procedural layer), and EXECUTE IMMEDIATE (procedural). There is no longer a legacy-parser fallback, so if one of these ever does reach row evaluation it throws — port it to a real node at that point. Any other unexpected node reaches visitChildren(RuleNode) and also fails loudly.

Constructor Details

ExpressionAstBuilder

public ExpressionAstBuilder()

Method Details

build

public Expression build(FrostlakeParser.BooleanExprContext ctx)

Build an Expression AST from a parsed booleanExpr (top) context.

visitValueExpr

public Expression visitValueExpr(FrostlakeParser.ValueExprContext ctx)

Boolean tier value alternative: drop straight through to the underlying value expression.

Specified by:

visitValueExpr in interface FrostlakeVisitor<Expression>

Overrides:

visitValueExpr in class FrostlakeBaseVisitor<Expression>

Parameters:

ctx - the parse tree

Returns:

the visitor result

visitParenExpr

public Expression visitParenExpr(FrostlakeParser.ParenExprContext ctx)

Description copied from class: FrostlakeBaseVisitor

Visit a parse tree produced by the ParenExpr labeled alternative in FrostlakeParser.expression().

The default implementation returns the result of calling AbstractParseTreeVisitor.visitChildren(org.antlr.v4.runtime.tree.RuleNode) on ctx.

Specified by:

visitParenExpr in interface FrostlakeVisitor<Expression>

Overrides:

visitParenExpr in class FrostlakeBaseVisitor<Expression>

Parameters:

ctx - the parse tree

Returns:

the visitor result

visitLiteralExpr

public Expression visitLiteralExpr(FrostlakeParser.LiteralExprContext ctx)

A literal, STAMPED with where it was written. The position is what lets a refusal point at an ARGUMENT rather than at the call — live's bad-rounding-mode sentence carries both, the call's offset on the prefix line and the argument's inside the detail.

Specified by:

visitLiteralExpr in interface FrostlakeVisitor<Expression>

Overrides:

visitLiteralExpr in class FrostlakeBaseVisitor<Expression>

Parameters:

ctx - the parse tree

Returns:

the visitor result

visitQualifiedNameExpr

public Expression visitQualifiedNameExpr(FrostlakeParser.QualifiedNameExprContext ctx)

Description copied from class: FrostlakeBaseVisitor

Visit a parse tree produced by the QualifiedNameExpr labeled alternative in FrostlakeParser.expression().

The default implementation returns the result of calling AbstractParseTreeVisitor.visitChildren(org.antlr.v4.runtime.tree.RuleNode) on ctx.

Specified by:

visitQualifiedNameExpr in interface FrostlakeVisitor<Expression>

Overrides:

visitQualifiedNameExpr in class FrostlakeBaseVisitor<Expression>

Parameters:

ctx - the parse tree

Returns:

the visitor result

visitOuterJoinColumnExpr

public Expression visitOuterJoinColumnExpr(FrostlakeParser.OuterJoinColumnExprContext ctx)

column(+) — the Oracle legacy outer-join marker. The (+) is a JOIN directive handled by the executor (which detects it at the parse-tree level and rewrites the comma-join into an outer join); as an expression the marked reference is just its plain column, so evaluation drops the marker.

Specified by:

visitOuterJoinColumnExpr in interface FrostlakeVisitor<Expression>

Overrides:

visitOuterJoinColumnExpr in class FrostlakeBaseVisitor<Expression>

Parameters:

ctx - the parse tree

Returns:

the visitor result

visitPriorExpr

public Expression visitPriorExpr(FrostlakeParser.PriorExprContext ctx)

PRIOR <column> — the parent-row side of a CONNECT BY step. Snowflake resolves only the bare column here (live-verified: a qualified PRIOR e.id fails with "invalid identifier"), so any qualifier is dropped and the reference binds to the parent row's copy of that column.

Specified by:

visitPriorExpr in interface FrostlakeVisitor<Expression>

Overrides:

visitPriorExpr in class FrostlakeBaseVisitor<Expression>

Parameters:

ctx - the parse tree

Returns:

the visitor result

visitConnectByRootExpr

public Expression visitConnectByRootExpr(FrostlakeParser.ConnectByRootExprContext ctx)

CONNECT_BY_ROOT <column> — the hierarchy root row's value of that column.

Specified by:

visitConnectByRootExpr in interface FrostlakeVisitor<Expression>

Overrides:

visitConnectByRootExpr in class FrostlakeBaseVisitor<Expression>

Parameters:

ctx - the parse tree

Returns:

the visitor result

visitSessionVarExpr

the visitor result

visitAnsiSubstringExpr

public Expression visitAnsiSubstringExpr(FrostlakeParser.AnsiSubstringExprContext ctx)

The ANSI SUBSTRING(<x> FROM <a> FOR <b>) spelling, which Snowflake refuses for every function name there is — SUBSTRING included. It reaches the builder at all so the refusal can be put on the FROM, which is where live puts it; the grammar alternative accepts nothing.

visitTypedLiteralArgExpr

public Expression visitTypedLiteralArgExpr(FrostlakeParser.TypedLiteralArgExprContext ctx)

An IDENTIFIER followed by a STRING inside a call, which live reads as a TYPED LITERAL and refuses by NAME rather than by syntax: TRIM(BOTH ' ') is "Unsupported data type literal 'BOTH ' ''" there, and UPPER(FOO ' ') is the same sentence with the same shape — so it is not a TRIM rule, it is the DATE '2020-01-01' form with an unknown word in front.

The whole point of the alternative is that it CONSUMES the pair. Without it the parse died on the string, so TRIM(BOTH ' ' FROM v) was refused there instead of on its FROM, where live refuses it. Nothing it matches is ever accepted.

Specified by:

visitTypedLiteralArgExpr in interface FrostlakeVisitor<Expression>

Overrides:

visitTypedLiteralArgExpr in class FrostlakeBaseVisitor<Expression>

Parameters:

ctx - the parse tree

Returns:

the visitor result
