SQLSelect — union array not initialized & name mismatch

[Ben-Gonzalez-97]

SQLSelect: initialize aUnion and fix name mismatch

• Component: src/ClassModules/SQLSelect.cls (declarations and initializer)

Problem

• Declares sUnion() while other code references aUnion(); not initialized in Class_Initialize.

Expected

Private aUnion() As Variant

Private Sub Class_Initialize()
    ReDim aJoin(0)
    ReDim vFields(0)
    ReDim aOrder(0)
    ReDim aUnion(0)
    ' ...
End Sub

Steps to Reproduce

1. Use UNION features without prior array setup.

Actual

• Append/iteration fails or produces wrong SQL.

Proposed Fix

• Rename to aUnion and ReDim in initializer.
