CREATE TABLE命令用于在Teradata中創(chuàng)建表。
CREATE <SET/MULTISET> TABLE <Tablename> <Table Options> <Column Definitions> <Index Definitions>;
CREATE SET TABLE EMPLOYEE,FALLBACK ( EmployeeNo INTEGER, FirstName VARCHAR(30), LastName VARCHAR(30), DOB DATE FORMAT 'YYYY-MM-DD', JoinedDate DATE FORMAT 'YYYY-MM-DD', DepartmentNo BYTEINT ) UNIQUE PRIMARY INDEX ( EmployeeNo );
創(chuàng)建表后,可以使用SHOW TABLE命令查看表的定義。
SHOW TABLE Employee; *** Text of DDL statement returned. *** Total elapsed time was 1 second. ------------------------------------------------------------------------ CREATE SET TABLE EMPLOYEE ,FALLBACK , NO BEFORE JOURNAL, NO AFTER JOURNAL, CHECKSUM = DEFAULT, DEFAULT MERGEBLOCKRATIO ( EmployeeNo INTEGER, FirstName VARCHAR(30) CHARACTER SET LATIN NOT CASESPECIFIC, LastName VARCHAR(30) CHARACTER SET LATIN NOT CASESPECIFIC, DOB DATE FORMAT 'YYYY-MM-DD', JoinedDate DATE FORMAT 'YYYY-MM-DD', DepartmentNo BYTEINT ) UNIQUE PRIMARY INDEX ( EmployeeNo );
