I feel stupid for asking this because it seems that MYSQL code isn't working the way that I think it should work.
Basically I wrote code like this:
select * from `Test_DC_Trailer` HAVING max(DR_RefKey);
Where the DR_RefKey is a unique numeric field that is auto iterated (like a primary key)... (7 Replies)

select_into
SELECT INTO(7) SQL Commands SELECT INTO(7)NAME
SELECT INTO - create a new table from the results of a query
SYNOPSIS
SELECT [ ALL | DISTINCT [ ON ( expression [, ...] ) ] ]
* | expression [ AS output_name ] [, ...]
INTO [ TEMPORARY | TEMP ] [ TABLE ] new_table
[ FROM from_item [, ...] ]
[ WHERE condition ]
[ GROUP BY expression [, ...] ]
[ HAVING condition [, ...] ]
[ { UNION | INTERSECT | EXCEPT } [ ALL ] select ]
[ ORDER BY expression [ ASC | DESC | USING operator ] [, ...] ]
[ LIMIT { count | ALL } ]
[ OFFSET start ]
[ FOR UPDATE [ OF tablename [, ...] ] ]
INPUTS
TEMPORARY
TEMP If specified, the table is created as a temporary table. Refer to CREATE TABLE [create_table(7)] for details.
new_table
The name (optionally schema-qualified) of the table to be created.
All other inputs are described in detail for SELECT [select(7)].
OUTPUTS
Refer to CREATE TABLE [create_table(7)] and SELECT [select(7)] for a summary of possible output messages.
DESCRIPTION
SELECT INTO creates a new table and fills it with data computed by a query. The data is not returned to the client, as it is with a normal
SELECT. The new table's columns have the names and data types associated with the output columns of the SELECT.
Note: CREATE TABLE AS [create_table_as(7)] is functionally equivalent to SELECT INTO. CREATE TABLE AS is the recommended syntax,
since SELECT INTO is not standard. In fact, this form of SELECT INTO is not available in PL/pgSQL or ecpg(1), because they interpret
the INTO clause differently.
COMPATIBILITY
SQL92 uses SELECT ... INTO to represent selecting values into scalar variables of a host program, rather than creating a new table. This
indeed is the usage found in PL/pgSQL and ecpg(1). The PostgreSQL usage of SELECT INTO to represent table creation is historical. It's
best to use CREATE TABLE AS for this purpose in new code. (CREATE TABLE AS isn't standard either, but it's less likely to cause confu-
sion.)
