List of makeFieldAccess() Examples

Examples of makeFieldAccess()

org.eigenbase.rex.RexBuilder.makeFieldAccess()
Creates an expression accessing a given named field from a record.
NOTE: Be careful choosing the value of {@code caseSensitive}. If the field name was supplied by an end-user (e.g. as a column alias in SQL), use your session's case-sensitivity setting. Only hard-code {@code true} if you are sure that the field name isinternally generated. Hard-coding {@code false} is almost certainly wrong.
@param expr Expression yielding a record @param fieldName Name of field in record @param caseSensitive Whether match is case-sensitive @return Expression accessing a given named field
