BTEQ工具命令

分享
更新时间:2020/08/05 GMT+08:00

BTEQ工具提供以下命令:

LOGOFF和QUIT

LOGOFF命令结束当前RDBMS会话,但不会退出BTEQ工具。

QUIT命令结束当前Teradata数据库会话,并退出BTEQ工具。

输入

SELECT 'StartDTTM' as a
            ,CURRENT_TIMESTAMP (FORMAT 'HH:MI:SSBMMMBDD,BYYYY') ;
.LOGOFF;
.QUIT;

输出

SELECT 'StartDTTM' as a
            ,CURRENT_TIMESTAMP (FORMAT 'HH:MI:SSBMMMBDD,BYYYY') ;
.LOGOFF;
.QUIT;

Gauss不支持上述命令,需要加注释。

.IF ERRORCODE和.QUIT

BTEQ命令,指定.IF和.QUIT。

输入

COLLECT STATISTICS 
 USING SAMPLE 5.00 PERCENT 
 COLUMN ( CDR_TYPE_KEY ) , 
 COLUMN ( PARTITION ) , 
 COLUMN ( SRC ) , 
 COLUMN ( PARTITION,SBSCRPN_KEY ) 
 ON DT_SDM.FCT_OTGO_NTWK_ACTVY_DAILY ;
 

输出

SET
default_statistics_target = 5.00 ;
ANALYZE DT_SDM.FCT_OTGO_NTWK_ACTVY_DAILY (CDR_TYPE_KEY) ;
ANALYZE DT_SDM.FCT_OTGO_NTWK_ACTVY_DAILY (PARTITION) ;
ANALYZE DT_SDM.FCT_OTGO_NTWK_ACTVY_DAILY (SRC) ;
ANALYZE DT_SDM.FCT_OTGO_NTWK_ACTVY_DAILY (PARTITION,SBSCRPN_KEY) ;
 RESET default_statistics_target ;

.IF

输入

.IF END_MONTH_FLAG <> 'Y' THEN .GOTO LABEL_1; 

输出

IF END_MONTH_FLAG <> 'Y' THEN
               GOTO LABEL_1 ;
END IF ;

.QUIT

输入

.IF ERRORCODE <> 0 THEN .QUIT 12;

输出

IF ERRORCODE <> 0 THEN
          RAISE EXCEPTION '12' ;
END IF;

.IF 与.QUIT

将.IF与.Quit移入语句块。

.Export FILE

将.EXPORT FILE修改为COPY,并将teradata实用程序设置为false。

Oracle语法

迁移后语法

.export file = $FILENAME;
select empno, ename from emp where deptno = 1;
COPY (select empno, ename from emp where deptno = 1) TO '$FILENAME' CSV HEADER DELIMITER E'\t';

.Export

当teradata实用程序设置为true时,应将.EXPORT FILE修改为$q$COPY,并移入语句块。

Oracle语法

迁移后语法

print BTEQ <<ENDOFINPUT;
   DATABASE HPBUS;
.export file = $FILENAME;
select empno, ename from emp where deptno = 1;

.QUIT 0;
