把这段代码改为doris的建表语句CREATE TABLE `aa_ccd` ( `ID` varchar(20) CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci NOT NULL, `CCDCODE` varchar(20) CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci NULL DEFAULT NULL, `ICNNAME` varchar(107) CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci NULL DEFAULT NULL, `ISDISEASE` varchar(20) CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci NULL DEFAULT NULL, `ENNAME` varchar(20) CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci NULL DEFAULT NULL, `PARENTID` varchar(20) CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci NULL DEFAULT NULL, `YEAR` varchar(4) CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci NULL DEFAULT NULL, `NOTE` varchar(200) CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci NULL DEFAULT NULL, `LEFTSPACE` varchar(10) CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci NULL DEFAULT NULL, `LIMITED` varchar(4) CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci NULL DEFAULT NULL, `LEVEL1` varchar(4) CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci NULL DEFAULT NULL, `LEVEL2` varchar(4) CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci NULL DEFAULT NULL, `LEVEL3` varchar(4) CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci NULL DEFAULT NULL, `LEVEL4` varchar(4) CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci NULL DEFAULT NULL, PRIMARY KEY (`ID`) USING BTREE, INDEX `index1`(`CCDCODE`) USING BTREE, INDEX `index2`(`ICNNAME`) USING BTREE, INDEX `index_yes`(`YEAR`) USING BTREE ) ENGINE = InnoDB CHARACTER SET = utf8mb4 COLLATE = utf8mb4_general_ci ROW_FORMAT = Dynamic;

您好!以下是将代码改为Doris建表语句的结果:
CREATE TABLE aa_ccd (
ID VARCHAR(20),
CCDCODE VARCHAR(20),
ICNNAME VARCHAR(107),
ISDISEASE VARCHAR(20),
ENNAME VARCHAR(20),
PARENTID VARCHAR(20),
YEAR VARCHAR(4),
NOTE VARCHAR(200),
LEFTSPACE VARCHAR(10),
LIMITED VARCHAR(4),
LEVEL1 VARCHAR(4),
LEVEL2 VARCHAR(4),
LEVEL3 VARCHAR(4),
LEVEL4 VARCHAR(4)
) DISTRIBUTE BY HASH(ID) BUCKETS 8 PROPERTIES("replication_num"="1");

根据报错信息,可以看到是在第25行出现了语法错误,缺少了逗号。具体来说,是因为在第24行的最后缺少了一个逗号,导致第25行的语句被解析为一个新的字段,而不是原本的字段属性。因此,应该在第24行最后加上逗号,即在 `LEVEL4` varchar(4) CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci NULL DEFAULT NULL 后面加一个逗号,就可以解决这个问题了。
mysql建表语句改为doris建表语句
要将 MySQL 数据库的建表语句转换为 Doris(Apache Doris)数据库的建表语句,需要了解 Doris 数据库的语法和支持的数据类型。以下是一个示例,将 MySQL 建表语句转换为 Doris 建表语句的过程:
假设有以下 MySQL 建表语句:
```sql
CREATE TABLE my_table (
id INT PRIMARY KEY,
name VARCHAR(100),
age INT,
salary DECIMAL(10, 2)
);
```
将其转换为 Doris 建表语句,可以使用以下代码作为参考:
```sql
CREATE TABLE my_table (
id INT,
name VARCHAR(100),
age INT,
salary DECIMAL(10, 2),
PRIMARY KEY (id)
)
DISTRIBUTED BY HASH(id) -- 根据 id 列进行数据分布
PROPERTIES (
'storage_type' = 'columnar' -- 指定存储类型为列式存储
);
```
上述代码中,我们将原始的 MySQL 建表语句进行了几个修改:
1. 移除了 `PRIMARY KEY` 关键字,将主键约束放在最后的 `PRIMARY KEY (id)` 中。
2. 添加了 `DISTRIBUTED BY HASH(id)`,根据 `id` 列进行数据分布。这是 Doris 的分布式表设计中的一个关键概念。
3. 添加了 `PROPERTIES` 子句,用于指定一些特定的表属性。在这个例子中,我们指定了存储类型为列式存储。
请注意,这只是一个示例,您需要根据实际情况进行修改和调整。Doris 支持的数据类型、表属性等可能与 MySQL 有所差异,您需要根据 Doris 的文档和要求进行相应的调整。
