Usage
Use this statement to create a new table. Use the TEMPORARY clause to specify that the table should be created as a local temporary table that is only visible to the current session. You may only use the following DDL statements on temporary tables:

   DROP TABLE
   RENAME TABLE
   EMPTY TABLE
   CREATE INDEX
   CREATE TEXT INDEX
   DROP INDEX
   RENAME INDEX

Use the READONLY clause to specify that a table is always read-only. Doing so can improve multi-user performance on a table because ElevateDB will not need to perform any locking on such a table.

FROM UPDATES Clause

Use the FROM UPDATES version of the CREATE TABLE statement to create a table that contains the contents of a replication update file. The format of the table created will be as follows:

"TableName" VARCHAR(40) COLLATE "ANSI_CI",
"UpdateType" VARCHAR(15) COLLATE "ANSI_CI",
"UpdateTimeStamp" TIMESTAMP,
"Manifest" CLOB COLLATE "ANSI_CI",
"KeyData" CLOB COLLATE "ANSI_CI",
"RowData" CLOB COLLATE "ANSI_CI"

The UpdateType column will contain one of the following values:

UpdateTypeDescription
InsertThe update is an insert operation. The RowData column will contain a CRLF-delimited list of column:value pairs.
UpdateThe update is an update operation. The KeyData column will contain a CRLF-delimited list of primary key column:value pairs, and the RowData column will contain a CRLF-delimited list of column:value pairs.
DeleteThe update is an update operation. The KeyData column will contain a CRLF-delimited list of primary key column:value pairs.

The Manifest column contains a CRLF-delimited list of published table IDs that serve to tell ElevateDB which published tables have loaded this update already.

For more information on replication, please see the Replication topic.

Examples
-- The following statement creates the Customer table

CREATE TABLE "Customer"
(
"ID" INTEGER GENERATED ALWAYS AS IDENTITY (START WITH 0, INCREMENT BY 1),
"Name" VARCHAR(30) COLLATE "ANSI_CI",
"Address1" VARCHAR(40) COLLATE "ANSI_CI",
"Address2" VARCHAR(40) COLLATE "ANSI_CI",
"City" VARCHAR(30) COLLATE "ANSI_CI",
"State" CHAR(2) COLLATE "ANSI_CI",
"Zip" CHAR(10) COLLATE "ANSI_CI",
"CreatedOn" TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
CONSTRAINT "ID_PrimaryKey" PRIMARY KEY ("ID"),
CONSTRAINT "ID_Check" CHECK (ID IS NOT NULL),
CONSTRAINT "Name_Check" CHECK (Name IS NOT NULL)
)

-- The following statement creates a temporary table containing
-- the contents of an update file

CREATE TEMPORARY TABLE "MainOfficeUpdates"
FROM UPDATES "MainOffice-2010-12-14 17-57-12.0306"
IN STORE MainUpdates

Required Privileges
The current user must be granted the CREATE privilege on the current database in order to execute this statement. Please see the User Security topic for more information.
