sqlserver建表sql语句:'entertained_end_date' bigint(20) DEFAULT NULL,中(20)报错原因

在 SQL Server 中,`bigint` 数据类型不需要指定长度,因为它总是占用 8 个字节的存储空间,所以不能使用 `(20)` 这样的长度限定符。如果你想让 `entertained_end_date` 字段为 `bigint` 数据类型并且可以为 `NULL`,可以使用以下 SQL 建表语句:
```
CREATE TABLE your_table_name (
-- 其他字段...
entertained_end_date bigint NULL,
-- 其他字段...
);
```
