) -> Result<()>
pub async fn insert_or_update_batch<T: Model>( &self, models: &[&T], ) -> Result<()>
批量插入或更新记录(遇到重复键时更新) turso 不支持 ON CONFLICT,因此通过 DELETE + INSERT 实现 upsert 语义。

&self,
models: &[&T],
) -> Result<()>
pub async fn insert_or_ignore_batch<T: Model>( &self, models: &[&T], ) -> Result<()>
批量插入或忽略记录(遇到重复键时忽略) turso 不支持 ON CONFLICT,因此通过捕获约束错误实现忽略语义。

Sourcepub async fn execute<T: Model>(&self, sql: &str) -> Result<Vec<T>>
pub async fn execute<T: Model>(&self, sql: &str) -> Result<Vec<T>>
执行原生 SQL 查询并返回模型列表 执行原生 SQL 查询并返回模型列表
Sourcepub async fn exec_table<T: Model>(&self, sql: &str) -> Result<Vec<T>>
👎Deprecated since 0.1.0: 请使用 execute 方法
pub async fn exec_table<T: Model>(&self, sql: &str) -> Result<Vec<T>>
请使用 execute 方法
执行原生 SQL 查询并返回模型列表(向后兼容)
Sourcepub async fn exec_non_query(&self, sql: &str) -> Result<u64>
pub async fn exec_non_query(&self, sql: &str) -> Result<u64>
执行原生非查询 SQL 并返回影响的行数
