Root Cause

The database driver does not support a specific Go type passed as a query argument, such as []byte without proper conversion.

generic

中文

数据库驱动不支持作为查询参数传递的特定 Go 类型，例如未正确转换的 []byte。

Workarounds

  1. 90% success 
    Convert []byte to a driver.Valuer: type ByteArray []byte; func (b ByteArray) Value() (driver.Value, error) { return []byte(b), nil }
  2. 80% success 
    Use a driver-specific type like pq.ByteaArray for PostgreSQL: args = append(args, pq.ByteaArray(data))

Dead Ends

Common approaches that don't work:

  1. 60% fail

    May not preserve binary data and can cause encoding issues.

  2. 80% fail

    Doesn't solve the underlying type mismatch.
