Description

现象描述： 1.第一次代码执行过程：C++连接数据后，创建一张新表，接着直接往新建表中插入一些数据，会报【failed to execute taos_stmt_bind_param_batch. error: column type mis-match with buffer type】 image image

2.第二次直接插入数据（表已存在），插入成功，不会报错。 image image

3.删除表，在【新建表】后添加睡眠10秒的逻辑，再次执行代码，现象与第一次相同。

Contributor guide

Research direction
Investigate the timing between table creation and data insertion in the C++ client. Check if the schema is fully propagated before the bind call. Look for any race conditions or caching issues.
