       --创建表reason。
openGauss=# CREATE TABLE tpcds.reason ( 
    CD_DEMO_SK          INTEGER          NOT NULL,
    CD_GENDER           character(16)            ,
    CD_MARITAL_STATUS   character(100)
)
;

--插入数据。
openGauss=# INSERT INTO tpcds.reason VALUES(51, 'AAAAAAAADDAAAAAA', 'reason 51');

--创建表reason_t1。
openGauss=# CREATE TABLE tpcds.reason_t1 AS TABLE tpcds.reason;

--为一个INSERT语句创建一个预备语句然后执行它。
openGauss=# PREPARE insert_reason(integer,character(16),character(100)) AS INSERT INTO tpcds.reason_t1 VALUES($1,$2,$3);

openGauss=# EXECUTE insert_reason(52, 'AAAAAAAADDAAAAAA', 'reason 52'); 

--删除表reason和reason_t1。
openGauss=# DROP TABLE tpcds.reason;
openGauss=# DROP TABLE tpcds.reason_t1;
