It is possible in MS SQL Server to store the results of query into a table, and most importantly, have the query create the table:
SELECT an_existing_column
INTO table_xyz
FROM an_existing_table
This is also possible in MySQL using:
CREATE TABLE table_xyz
SELECT an_existing_column
FROM an_existing_table
I have searched the Apache Derby Reference Guide and cannot see a method for achieving similar behaviour.
Does anyone know if this possible in Apache Derby?

Store the results of a query into a table:
INSERT INTO table_xyz (an_existing_column) SELECT an_existing_column FROM an_existing_table;
Create a table from another table:
All Columns:
CREATE TABLE table_xyz AS SELECT * FROM an_existing_table WITH NO DATA;
Specific Column:
CREATE TABLE table_xyz AS SELECT an_existing_column FROM an_existing_table WITH NO DATA;

For all columns:
Step 1: Create a new table with a different name. for example, my_new_table:
CREATE TABLE my_new_table AS SELECT * FROM original_table WITH NO DATA;
This statement creates a new table from original table in the same format and no data copied. It is required to specify WITH NO DATA
for it creates a new table with the same columns.
Step 2: Copy data from orig_table to my_new_table using INSERT INTO
.
INSERT INTO my_new_table SELECT * FROM orig_table.
Then you will have all the data copied.
