根因分析

提供给预编译语句的参数数量与查询中的占位符数量不匹配。

解决方案

  1. 90% 成功率 Use named parameters with sql.Named 
    stmt, err := db.PrepareContext(ctx, "INSERT INTO users(name, age) VALUES(@name, @age)")
if err != nil { return err }
_, err = stmt.ExecContext(ctx, sql.Named("name", "Alice"), sql.Named("age", 30))

无效尝试

常见但无效的做法:

  1. Counting placeholders manually 70% 失败

    Error-prone for complex queries; use named parameters or helper functions.
