Why a HOLE exists — which producer limitation created it.

Enum Constant Summary

Enum Constants
Enum Constant and Description
`FLOW_DEPENDENT_VARIABLE` A variable whose value depends on control flow the evaluator cannot decide: assigned inside an undecidable IF / WHILE branch, declared there, or assigned by a driver loop whose iteration is unknown.
`INEXACT_TRANSFORM` A transform was folded for display but its output is not proven byte-exact against vendor runtime semantics (CAST/CONVERT padding and styles, collation-aware REPLACE/UPPER/LOWER, whitespace-class TRIM, non-default QUOTENAME delimiters, numeric rendering).
`NON_VARIABLE_IDENT` A bare (non-variable) identifier used as a value — data-dependent.
`OPAQUE_CALL` A function call the evaluator does not fold.
`QUERY_ASSIGNED_VARIABLE` A variable whose last visible assignment read from a query (`SELECT @v = col FROM t ...`): its value is runtime data.
`RESOURCE_LIMIT` Evaluation hit a configured resource bound.
`UNBOUND_VARIABLE` A variable/parameter never bound and never assigned a foldable value.
`UNSUPPORTED_EXPR` An expression form the evaluator does not model.

  - UNBOUND_VARIABLE
```
public static final SqlFragment.HoleOrigin UNBOUND_VARIABLE
```
    A variable/parameter never bound and never assigned a foldable value.
  - NON_VARIABLE_IDENT
```
public static final SqlFragment.HoleOrigin NON_VARIABLE_IDENT
```
    A bare (non-variable) identifier used as a value — data-dependent.
  - OPAQUE_CALL
```
public static final SqlFragment.HoleOrigin OPAQUE_CALL
```
    A function call the evaluator does not fold.
  - UNSUPPORTED_EXPR
```
public static final SqlFragment.HoleOrigin UNSUPPORTED_EXPR
```
    An expression form the evaluator does not model.
  - RESOURCE_LIMIT
```
public static final SqlFragment.HoleOrigin RESOURCE_LIMIT
```
    Evaluation hit a configured resource bound.
  - INEXACT_TRANSFORM
```
public static final SqlFragment.HoleOrigin INEXACT_TRANSFORM
```
    A transform was folded for display but its output is not proven byte-exact against vendor runtime semantics (CAST/CONVERT padding and styles, collation-aware REPLACE/UPPER/LOWER, whitespace-class TRIM, non-default QUOTENAME delimiters, numeric rendering).
  - QUERY_ASSIGNED_VARIABLE
```
public static final SqlFragment.HoleOrigin QUERY_ASSIGNED_VARIABLE
```
    A variable whose last visible assignment read from a query (SELECT @v = col FROM t ...): its value is runtime data. The hole keeps the assignment's own rendering (the source column name as a placeholder) but is named after the VARIABLE, and SqlFragment.valueOrigin describes the column / expression the value would come from.
  - FLOW_DEPENDENT_VARIABLE
```
public static final SqlFragment.HoleOrigin FLOW_DEPENDENT_VARIABLE
```
    A variable whose value depends on control flow the evaluator cannot decide: assigned inside an undecidable IF / WHILE branch, declared there, or assigned by a driver loop whose iteration is unknown.

  - values
```
public static SqlFragment.HoleOrigin[] values()
```
    Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:
```
for (SqlFragment.HoleOrigin c : SqlFragment.HoleOrigin.values())
    System.out.println(c);
```
    Returns:
    
    an array containing the constants of this enum type, in the order they are declared
  - valueOf
```
public static SqlFragment.HoleOrigin valueOf(String name)
```
    Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
    
    Parameters:
    
    name - the name of the enum constant to be returned.
    
    Returns:
    
    the enum constant with the specified name
    
    Throws:
    
    IllegalArgumentException - if this enum type has no constant with the specified name
    
    NullPointerException - if the argument is null
