	Table Properties	Specifies a list of key-value pairs used to tag the table definition
	Using	Specifies the file format for the CTAS	For example, TEXT.
	Options	Specifies the table options to optimize table behavior	You can enter key-value pairs to define options for the table.
	Version As	Specifies the version of a Delta CTAS	This option is part of temporal specification and references a Delta table using its version.
	Timestamp As	Specifies a timestamp of a Delta CTAS	This option is part of temporal specification and references a Delta table at the specified point in time.
Storage	Fields Terminated By	Specifies a character that defines column separator	For example, comma ' , '.
	Fields Escaped By	Defines the escape mechanism
	Collection Items Terminated By	Specifies a character that defines collection item separator	For example, underscore ' _ '.
	Map Keys Terminated By	Specifies a character to define a map key separator	For example, colon ' : '.
	Lines Terminated By	Specifies a row separator character	For example, new line ' \n '.
	Null Defined As	Defines a value for NULL	For example, ' foonull'.
	Serde Handler Class	Specifies a fully-qualified class of a custom SerDe	Default classes are available when Stored As is set to ORC, AVRO, or PARQUET.
	Stored As	Specifies the file format for the CTAS
	Input Format	Specifies the input format for the CTAS	Default input formats are available when Stored As is set to TEXTFILE, SEQUENCE FILE, ORC, PARQUET, AVRO, or RCFILE.
	Output Format	Specifies the output format of the CTAS	Default output formats are available when Stored As is set to TEXTFILE, SEQUENCE FILE, ORC, PARQUET, AVRO, or RCFILE.
	Stored By	Specifies a non-native table format using a storage handler	For example, org.apache.hadoop.hive.hbase.HBaseStorageHandler
	Serde Properties	Specifies a list of key-value pairs used to define SerDe properties
Select	Available Tables and Views	Specifies a list of tables and views selected under From	Under Available Tables and Views, select the columns that you want to include in CTAS. Then, click .
	Columns	Specifies the selected CTAS columns
	Select Type	Specifies the expression type to indicate whether duplicate rows are returned	All: Indicates that the statement returns all rows, including duplicate rows Distinct: Indicates that the statement discards duplicate rows and returns only the remaining rows
	Alias	Specifies a temporary name given to a table, column, or expression present in a query based on the selected column
	Expression	Specifies the expression for a selected column	Available only when the selected column is a user-defined function expression
From	Available Tables and Views	Specifies a list of available tables and views	Under Available Tables and Views, select the tables or views from which you want to select columns. Then, click .
	From	Specifies a list of selected tables or views from which columns are selected
	Alias	Specifies an alternate name for the selected table or view
User Defined SQL	User-Defined SQL	Specifies whether the SQL code used in Forward Engineering is defined using the User Defined SQL tab
SQL		Specifies the SQL code used during Forward Engineering

Selecting User-Defined SQL check box ensures that SQL code on the User Defined SQL tab is used in Forward Engineering. Hence, if you have selected the User-Defined check box and made changes in CTAS properties then, you must alter the User Defined SQL accordingly to reflect the changes in Forward Engineering.
