Methods Summary
public static voidgenerateScalarColumns(org.hibernate.hql.ast.tree.HqlSqlWalkerNode node, java.lang.String[] sqlColumns, int i)
Generates the scalar column AST nodes for a given array of SQL columns

		if ( sqlColumns.length == 1 ) {
			generateSingleScalarColumn( node, i );
		}
		else {
			ASTFactory factory = node.getASTFactory();
			AST n = node;
			n.setText( sqlColumns[0] );	// Use the DOT node to emit the first column name.
			// Create the column names, folled by the column aliases.
			for ( int j = 0; j < sqlColumns.length; j++ ) {
				if ( j > 0 ) {
					n = ASTUtil.createSibling( factory, SqlTokenTypes.SQL_TOKEN, sqlColumns[j], n );
				}
				n = ASTUtil.createSibling( factory, SqlTokenTypes.SELECT_COLUMNS, " as " + NameGenerator.scalarName( i, j ), n );
			}
