db_insert_batch	function	go	infra	1.0.0	impure	func DBInsertBatch(db *sql.DB, table string, columns []string, rows [][]any) (int64, error)	Inserta multiples filas en una transaccion usando prepared statement. Retorna el total de filas afectadas. Mas eficiente que llamar DBInsertRow en un loop.	database sql insert batch transaction bulk	db_insert_row_go_infra			false	error_go_core	database/sql strings	false			functions/infra/db_insert_batch.go

Ejemplo

cols := []string{"name", "score", "ts"}
rows := [][]any{
    {"Alice", 95.5, 1700000000},
    {"Bob",   87.2, 1700000001},
    {"Carol", 91.0, 1700000002},
}
n, err := DBInsertBatch(db, "results", cols, rows)
if err != nil {
    return err
}
fmt.Printf("insertadas: %d filas\n", n)

Notas

Usa tx.Prepare() + stmt.Exec() en un loop dentro de una transaccion. El rollback es automatico si alguna fila falla. Valida tabla y columnas con regex. Cada fila debe tener exactamente len(columns) valores — retorna error descriptivo si no coincide.
