Teradata sql Select 失败 [2616] 计算期间发生数字溢出
Teradata sql Select Failed [2616] Numeric Overflow occurred during computation
我得到：
Error 2616 (Numeric overflow occurred duing computation)
当我运行下面的代码。我开发了 2 个单独的查询，每个查询 运行。当我将它们放在一个查询中并使用 UNION 时，我收到了错误消息。联合的一侧 returns 274 条记录，另一侧 returns 277 条记录。当我收到此消息时，我正在使用 Teradata SQL Assistant。我们正在使用版本 14.10.0.07.

我假设您的两个查询 运行 都可以。 UNION 运算符：
Combines the results of two or more queries into a single result set
that includes all the rows that belong to all queries in the union.
The UNION operation is different from using joins that combine columns
from two tables.
The following are basic rules for combining the result sets of two
queries by using UNION:
The number and the order of the columns must be the same in all queries.
The data types must be compatible.
我看不到你的数据并复制它，但我猜你有 DECIMAL/NUMERIC 列与第二个 SELECT 不兼容。检查它的最简单方法是注释两个语句中的所有列，除了一列和 运行 您的查询每次都取消注释一列。当您找到导致错误的列时，请使用：
CAST(col_name AS type) -- where type is broader type

可能您需要转换硬编码 0.00 AS BANK_AMT ，它被视为 DECIMAL(3,2):
CAST(0.00 AS DECIMAL(18,2)) AS BANK_AMT
来自@anwaar_hell评论和Teradata UNION:
All SQL statements being combined with UNION, have to return the same
number of columns, furthermore, the datatypes of all columns across
the participating select statements have to match. If they don’t
match, the data types of the very first SQL select statement will be
the relevant one and not matching columns of the other select
statements will be implicitly casted to the same data type the very
first select statement has.
Keep this in mind, especially if your column is a character data type,
as this could cause hidden truncation of text columns; This is a
problem which is very difficult to discover.
在其他 RDBMS 中，例如 Oracle/SQL 服务器，数据类型被隐式转换为更广泛的类型。
更正这个
CAST(0 AS DECIMAL(18,2)) for BANK_AMT
