Implementations§

Source§

impl TableService

Source

pub async fn list_tables( db: &DatabaseConnection, schema: Option<&str>, ) -> Result<Vec<TableInfo>, TableError>

获取所有表信息(PostgreSQL)

§注意

此方法需要 PostgreSQL 数据库,并且需要能够执行查询操作。 由于 SeaORM 的 DatabaseConnection 不直接支持复杂查询结果解析, 建议使用 sqlx 连接池或通过其他方式获取查询结果。

§参数
  • db - 数据库连接
  • schema - Schema 名称(可选,默认为 “public”)
§替代方案

如果需要获取表列表,可以:

  1. 使用 sqlx 连接池直接查询
  2. 使用 SeaORM Entity 查询(如果已定义表 Entity)
  3. 通过数据库管理工具查询
Source

pub async fn get_table_info( db: &DatabaseConnection, schema: Option<&str>, table_name: &str, ) -> Result<TableInfo, TableError>

获取指定表的信息

§注意

此方法需要 PostgreSQL 数据库,并且需要能够执行查询操作。 由于 SeaORM 的 DatabaseConnection 不直接支持复杂查询结果解析, 建议使用 sqlx 连接池或通过其他方式获取查询结果。

§参数
  • db - 数据库连接
  • schema - Schema 名称(可选,默认为 “public”)
  • table_name - 表名称
Source

pub async fn get_table_columns( db: &DatabaseConnection, schema: Option<&str>, table_name: &str, ) -> Result<Vec<TableColumnInfo>, TableError>

获取表的所有列信息(PostgreSQL)

§注意

此方法需要 PostgreSQL 数据库,并且需要能够执行查询操作。 由于 SeaORM 的 DatabaseConnection 不直接支持复杂查询结果解析, 建议使用 sqlx 连接池或通过其他方式获取查询结果。

§参数
  • db - 数据库连接
  • schema - Schema 名称(可选,默认为 “public”)
  • table_name - 表名称
Source

pub async fn table_exists( db: &DatabaseConnection, schema: Option<&str>, table_name: &str, ) -> Result<bool, TableError>

检查表是否存在
