使用 BTEQ 插入到 teradata 时的无效时间戳

Question

所以我想在之前用 bteq 创建的 table 中插入一些东西。我已经用谷歌搜索了这个（例如 here），但是我已经在该列上进行了投射并且没有消除错误。

创建语句如下所示：

.logmech LDAP
.logon databae/user_id,pwd
.set width 256
.set retcancel on database libname;
DATABASE libname;
create MULTISET table libname.IRIS( "SEPAL_LENGTH" FLOAT,  "SEPAL_WIDTH" FLOAT,  "PETAL_LENGTH" FLOAT,  "PETAL_WIDTH" FLOAT,  "TARGET" FLOAT,  "TIMESTAMP1" TIMESTAMP(6) FORMAT 'YYYY-MM-DDBHH:MI:SS.S(6)' DEFAULT NULL ,  "NULL_VALUES" FLOAT) UNIQUE PRIMARY INDEX("TimeStamp1");
.QUIT
.LOGOFF
.EXIT

插入语句如下所示：

.logmech LDAP
.logon databae/user_id,pwd
.set width 256
.set retcancel on database libname;
DATABASE libname;
.IMPORT VARTEXT FILE =/path_to_file/data.csv, skip=1;
.REPEAT *
USING "SEPAL_LENGTH" (varchar(2000)),  "SEPAL_WIDTH" (varchar(2000)),  "PETAL_LENGTH" (varchar(2000)),  "PETAL_WIDTH" (varchar(2000)),  "TARGET" (varchar(2000)),  "TIMESTAMP1" (varchar(2000)),  "NULL_VALUES" (varchar(2000)) 
INSERT INTO IRIS_delete VALUES(cast( :"SEPAL_LENGTH"  as FLOAT), cast( :"SEPAL_WIDTH"  as FLOAT), cast( :"PETAL_LENGTH"  as FLOAT), cast( :"PETAL_WIDTH"  as FLOAT), cast( :"TARGET"  as FLOAT), cast( :"TIMESTAMP1"  as TIMESTAMP(6) FORMAT 'YYYY-MM-DDBHH:MI:SS.S(6)'), cast( :"NULL_VALUES"  as FLOAT));
.QUIT
.LOGOFF
.EXIT

通过执行插入语句我得到错误：

*** Failure 6760 Invalid timestamp. Statement# 1, Info =0

以下是 csv 的一些示例：

|sepal_length|sepal_width|petal_length|petal_width|target|TimeStamp1|Null_values 0|5.1|3.5|1.4|0.2|0.0|2018-09-18 13:26:30.583216|

1|4.9|3.0|1.4|0.2|0.0|2018-09-18 13:26:30.583216|

2|4.7|3.2|1.3|0.2|0.0|2018-09-18 13:26:30.583216|

3|4.6|3.1|1.5|0.2|0.0|2018-09-18 13:26:30.583216|

4|5.0|3.6|1.4|0.2|0.0|2018-09-18 13:26:30.583216|

5|5.4|3.9|1.7|0.4|0.0|2018-09-18 13:26:30.583216|

6|4.6|3.4|1.4|0.3|0.0|2018-09-18 13:26:30.583216|

7|5.0|3.4|1.5|0.2|0.0|2018-09-18 13:26:30.583216|

8|4.4|2.9|1.4|0.2|0.0|2018-09-18 13:26:30.583216|

9|4.9|3.1|1.5|0.1|0.0|2018-09-18 13:26:30.583216|

你知道时间戳有什么问题吗？

Answer 1

Mimi，您的 bteq 脚本中的列数和顺序与数据文件不匹配检查以下示例中脚本中指定的列和文件中的列数

"SEPAL_LENGTH" (1),  "SEPAL_WIDTH"(2),  "PETAL_LENGTH"(3),  "PETAL_WIDTH"(4),  "TARGET"(5),  "TIMESTAMP1"(6),  "NULL_VALUES"(7)

col1->0|  col2->5.1|  col3->3.5|  col4->1.4|  col5->0.2|  col6->0.0|  col7->2018-09-18 13:26:30.583216|  col8->

您可以通过在 table 和 bteq 脚本中的时间戳列之前再添加 1 列来解决您的问题，如下所示，我在时间戳列

之前添加了 "TARGET1"

USING "SEPAL_LENGTH" (varchar(2000)),  "SEPAL_WIDTH" (varchar(2000)),  "PETAL_LENGTH" (varchar(2000)),  "PETAL_WIDTH" (varchar(2000)),  "TARGET" (varchar(2000)),  "TARGET1" (varchar(2000)),  "TIMESTAMP1" (varchar(2000)),  "NULL_VALUES" (varchar(2000)) 
INSERT INTO IRIS_delete VALUES(cast( :"SEPAL_LENGTH"  as FLOAT), cast( :"SEPAL_WIDTH"  as FLOAT), cast( :"PETAL_LENGTH"  as FLOAT), cast( :"PETAL_WIDTH"  as FLOAT), cast( :"TARGET"  as FLOAT), cast( :"TARGET1"  as FLOAT), cast( :"TIMESTAMP1"  as TIMESTAMP(6) FORMAT 'YYYY-MM-DDBHH:MI:SS.S(6)'), cast( :"NULL_VALUES"  as FLOAT));

使用 BTEQ 插入到 teradata 时的无效时间戳
