创建表时，你可以使用 VECTOR 数据类型声明指定列为向量列。 例如，要创建一个带有三维 VECTOR 列的 embedded_documents 表，可以使用 MySQL CLI 执行以下 SQL 语句： USE test; CREATE TABLE embedded_documents ( id INT PRIMARY KEY, -- document 列存储文档的原始内容 document TEXT 预期输出如下： Query OK, 0 rows affected (0.27 sec) 第 3 步：向表中插入向量 向 embedded_documents 表中插入三行，每一行包含数据和数据的向量嵌入： INSERT INTO embedded_documents VALUES (1, 'dog', '[1,2,1]'), (2, 'fish', '[1,2,4]'), (3, 'tree' 在实际应用中，嵌入模型通常会生成数百或数千维的向量。 第 4 步：查询向量表 要验证上一步中的三行数据是否已正确插入，可以查询 embedded_documents 表： SELECT * FROM embedded_documents; 预期输出如下： +----+----------+-----------+ | id | document | embedding | +--
