CREATE TABLE¶

Description¶

Creates a new table in the current database. You define a list of columns, which each hold data of a distinct type. The owner of the table is the issuer of the CREATE TABLE command.

For more information, please refer to CREATE TABLE documentation.

TEMPORARY TABLES¶

Description¶

In Sybase IQ GLOBAL | LOCAL TEMPORARY is used to create temporary tables that exist only for the session. These tables are session-specific and automatically deleted when the session ends. They help store intermediate results or work data without affecting the permanent database schema. It also can be created only by adding an # at the beginning of the name.

Warning

This syntax is partially supported in Snowflake.
