In current database systems, users have to group and replace data for queries by writing CASE statements using Structured Query Language (SQL) code. Writing SQL CASE statements by hand requires users to know CASE syntax, as well as to know the data and the data's underlying structures that are to be processed. The CASE statement also has different syntaxes for different situations. For example, the CASE statement has different syntaxes depending upon whether the user is replacing discrete values and/or replacing a range of values.
